Hi,

I'm just going through my last *stability* tests, and would like to begin
testing the overclocking aspects of my new rig.

I wanted to get the machine *Rock-Solid* using stock settings, now I got a
solid base to work from on my overclocking!

Intel® Pentium® 4 - 2.6GHz
Intel® Retail HSF
ABIT AI7 (BIOS #16)
512MB CORSAIR PC3200 (on Loan)
ANTEC TRUE550

I also have a THERMALRIGHT SP-94 + 92mm YS-TECH on standby, but I wanna see
what I can do with the retail unit first.

What would you say is the standard procedure for testing your CPU and mobo's
FSB?. I know I should take the memory out the equation by setting loose
timings, and also running the 5:4 divider, but what about the CPU?.

This is my first attempt at overclocking a Intel® P4, so I wanna take it all
in. Do you guys say just push up the FSB like 5MHz at a time, and then try
to boot up and run some Prime95, then if you fail that, nudge up the vCore a
bit?.

I read some reports of people running great overclocks using stock vCore
(1.525v). I don't expect that myself, but I have been reading that up to
1.65v is fairly safe, as long as proper cooling is in place.

So is that what I should do, relax the memory and start pushing 5MHz at a
time, then if I hit problems just bump up the vCore?

I have almost the same setup, AI7 (BIOS 16), P4 2.6C (800MHz), 1GB Kingston
PC3200, Coolermaster Aero 4 (copper, 2800RPM, very quiet), currently running
218MHz (1:1).

Be forewarned, the AI7 is a fine mobo, but the OC'ing ability of this
particular mobo has proven to be inconsistent, more than I can recall w/ any
other Abit mobo. It seems either you get a GREAT mobo (insane OCs to 250,
260, or more), or mediocre results (230, if you're lucky). Unfortunately,
I'm with many others in the latter category, the system simply will not run
stable above 218MHz sync. I can just barely run 230MHz FSB w/ 5:4 without
XP hanging on boot-up, so it's not the memory. And believe me, I'm VERY
experienced and worked on this mobo for TWO MONTHS, to the point of
exhaustion, it just won't do it. So just beware, keep your fingers crosses.

As I said, I can't run the CPU FSB above 230Mhz, and can't run the memory
past 218MHz. So that leaves me little choice, either run CPU FSB 230MHz
(5:4), and thus seriously underclock the memory, or run 218MHz (1:1) and
sacrifice some CPU OC'ing to keep the memory tapped out, and sync'd. Not a
great situation, my only option being to get some PC4000 perhaps. But at
today's prices, and given I don't think I'll being seeing anything more than
CPU FSB 230MHz anyway, I decided to stay put. I was *hoping* to run CPU FSB
250 (5:4), apparently this is a pipe-dream. Even tried water cooling, no
dice. Yet others run the mobo 250 and up, I'm stumped.

Since the P4 CPU is far more likely to be overclockable, I like to isolate
the memory by overclocking the CPU FSB and memory in sync (1:1). IOW, try
running 210, 220, 230, etc. In most cases, you'll tap out memory before the
CPU (for me, that was 220MHz). I determined this using Memtest-86, NOT
Windows. Windows is too demanding, takes to long to reboot, etc. And just
because Memtest-86 runs clean, doesn't mean Windows will. Many attempts to
OC in Memtest-86 ran fine, then hung Windows within seconds.

I usually keep the memory at SPD until I tap it out, then start losening the
timings, to see how much more I can gain. At that point, that's my upper
memory limit. I then return to the SPD settings, then start tightening the
timings, again, until it becomes unstable under Memtest-86, that's my lower
limit. When completed, I have a low/high range for the memory. Of course,
during this process, I'm adjusting vDimm to see if it helps, within reason,
as necessary.

Now I turn to the CPU. In this case, I suggest runnung 5:4 so that memory
now doesn't hinder the results (i.e., it's always underclocked, at least
until CPU FSB 250MHz). As with memory, I'm increasing voltage within
reason, as necessary when instability occurs.

Again, all this is under Memtest-86. When completed, I have a pretty good
idea what the the CPU and memory can do, individually. I now try running
Windows, which invariably can't handle the maximum OC under Memtest. I
start working backwards, reducing CPU and memory OC's until Windows
stability returns. Once Windows loads and run (or appears to run) stable, I
run Prime95. Ultimately, I never accept OC'ing results until Prime95 runs
24 hours, no errors.

I strongly suggest keeping a diary, it really helps. You're adjusting a lot
of variables, and it can get awfully difficult to keep track. The last
thing you want to do is spend two hours mucking w/ the system, then lose
track of where you are. List all the variable (FSB, memory, voltages,
etc.), I even track memtest wall time to see if perhaps the OC is higher,
but results are deminishing (sometimes happens on asynch CPU/DRAM ratio!).

Hi Jim,
thanks for that detailed reply, I found it very useful! Obviously I'm not
sure what to expect, but I was kinda hoping to reach 250MHz-FSB with a 5:4
memory ratio, but I guess that depends on whether the CPU or Mobo can handle
those figures.

Reading your story it sounds like your CPU may be in question. If only you
had a different P4 to test, or some different RAM.

I finally got my rig *Bullet-Proof* (12Hours Prime95 + 3DMark01) using stock
settings. Had a nightmare trying to run some brand-new OCZ Platinum PC3200
Limited-Edition at any decent timings, took me 8 days of ranting/testing to
finally see it wasn't gonna happen, and sent the memory back for testing and
*loaned* a stick of nice Corsair.

Anyway I figure that I will set the memory to 5:4, then bump up the FSB by
10MHz a time to 230MHz, then slowly begin pushing from there.

I too had doubts about the AI7, but actually I am beginning to like it now.
.. .my first Pentium board since my trusty BE6-II v1.1. I been chatting to a
guy called *Navig* over in the ABIT forums, and he running his AI7 at
300MHz-FSB with a P4c 2.4GHz.

Also I'm aware of something that happens on different ABIT systems that I
have built. Basically if you are trying to work your way upwards in an
overclock (CPU/FSB whatever) you will get to a stage which you cannot pass,
and will need to *leap-frog*. The last time I had this was with working on
a recent AMD build using an AN7. I was trying to test out a T-Bred XP2400+
CPU on a 200MHz-FSB BUS (10x200), this CPU normally uses a 133MHz BUS
(15x133). Anyway no matter what I tried it just wouldn't boot at 10x200=
2GHz which was the CPU's default GHz, so after some head-scratching I
thought Sod-it, lets try higher and changed the settings to 11x200 (2.2GHz)
and wouldn't you know it the PC booted and was stable. This scenario will
catch out people like me who like to work their way *linearly* upwards, but
sometimes you just need to skip this patch and resume on the other side.

In the case of the AMD system, I was able to get that chip up to 2.4GHz
stable using nearly 1.9vCore, but temps were a bit too much for the retail
HSF :p 

Anyway I hope what I said made some sense, and I will let you know how I get
on. . .

I usually start by bouncing the FSB up a fair chunk without getting greedy
just to get the first "chunk" out of the way. from there, I increment by 2
Mhz until I find instability and back off a bit.

at this stage, you have to decide what your approach is going to be...
upping the voltage to the CPU and continuing forward or what...

Hi Tom,
thanks for reply, I promise not to bite your head off today :p 

One thing I was wondering, how can you separate your CPU and FSB when you
start to hit errors?

I can adjust vCore if I think my CPU is getting a bit ragged, but what can I
do if I suspect my boards FSB is getting wobbly? is there anyway to adjust
northbridge voltages? or any other tools to help stabilize a overclocked
system bus?

thanks as always

Well, if I can't run, say, FSB 235 (5:4), thereby underclocking PC3200 to
188MHz (vs. 200MHz spec), yet, I can run FSB 218MHz (1:1), no problem, I
think it's safe to say memory is at least an issue. Even totally relaxed
memory timings maxs no difference. Now, is it possible that running asynch
(vs. sync) is itself causing a problem?! Maybe. IOW, if perhaps I had
PC4000, maybe I *could* run FSB 250 (1:1). I've certainly considered it.
Problem is, at these prices, who wants to run out an get PC4000 only to end
up tapping out a 230 (1:1)! That's my dilemma. Perhaps if I found a deal
on PC4000, I'd give it a whirl, but right now, it's not even a remote
possibility. I originally got the PC3200 for a mere $176! Even that's now
$286, on sale! no less.

Trust me, I didn't go into the half of it regarding everything I tried. I
reseated the Northbridge, disabled overdrive features, reduced memory
timings, water cooling, changing DIMM slots, running HSF full bore, running
default BIOS settings, vDIMM up to 2.8v, vCore up to 1.8v!, to name a few,
even took to literally blowing an 80mm fan directly on the Northbridge, it
just doesn't matter. Unless my CPU is simply a dud, something on this mobo
is holding me back, I'd sure like to know what.

Hi,

I am running 13x 231 (3GHz) with 1.6vCore with 57°C Max-Load running Prime95
stable now for a few hours.

I can boot WindowsXP Pro at 240/250MHz-FSB but Prime95 will fail in the
first minute?

The AI7 is indeed *undervolting* the vCore, so even though I have 1.6v set
in BIOS, it is reading 1.57-1.59vCore in uGuru.

Not sure if my CPU has maxed out *or* the mobo is having trouble with the
240-250MHz-FSB? but Windows loads fine, just Prime95 will error out very
quickly.

The PC3200 Memory is running 5:4 with very slow SPD timings and GAT is
A-A-A-D-D, so I don't think that is causing any issues *unless* the board
doesn't like SLOW timings?

Hehe so much for reaching 3.25GHz-CPU & 1GHz-FSB :p 

Hmm what else, the AGP is still default 1.55v, the PSB strap is 800. I feel
like I want to give the northbridge/chipset some more juice but I don't
think I can?

How high can I go with the vCore? is 1.75v getting risky (as long as the
cooling is ok?).

Or maybe I just hit the ceiling of my humble SL6WS Costa P4c 2.6GHz (@3GHz)?

Jim, Wayne,
I'm really interested to see how you make out w/ the various settings as I'm
about to build a similar PC. Please post back w/ your results.
Waiting on UPS...tap,tap,tap.

IC7
P4 2.4c stock HS&f
OCZ EL Gold 3700 rev.2 (2x256mb)
(2) Hitachi 80gb SATA hd's
Radeon 9100 128mb AGP
Thermaltake 420w PSU

I used to overclock w/ my BE6-II and liked to think I was semi
knowledgable on the matter, but all these new mobo/ram settings
really have me confused...PBWM
I will definately follow your suggestion on how/where to start OC'ing.
Do either of you have any input for me concerning the actual build of the
PC? How about ideas on loading XP. I heard there is a definite right &
wrong order of things to do....mostly w/ drivers.

TIA for any help
Keith

Hi,
well I have my own way of building, which is to start fairly bare-bones (no
HDD or Optical) just the floppy. I roughly arrange the cables and stuff,
but I keep it a little rough to start, as normally I rebuild the system
completely after I know it is rock stable and overclocking well. I don't
take off the northbridge fan or anything like that, until I am certain that
everything is working at stock.

So on my current build, the cables are pretty neat, and allot of then are
sheathed, will make it perfect soon. This time I did start with the retail
INTEL HSF, so I can test it out and learn how it performs, but I have just
bought a nice looking Thermalright SP-94 + YS-Tech 92mm fan to take the
place of the stock unit.

As far as Windows installation and drivers, well I let XP partition and
format my RAID-0 boot drive for me, all done from the WindowsXP CD-ROM.
Once Windows was installed I:

1) Installed chipset drivers from my CD
2) Installed my graphics-card drivers (CAT 3.7)
3) Install DX 9.0b

simple really, I also have the INTEL IAA RAID edition installed, dunno what
it does? :p

Keith,

The basic build isn't all that complicated, but managing the OC is time
consuming and requires *some* sort of methodology to make sure you're
drawing the proper conclusions. I find many people OC too quickly, never
taking the time to insure the system is stable. I'm not even interested in
OC'ing for at least a couple weeks, I'm looking for stability initially.

Regarding the install...

On a new build, I always install BootIt NG ( http://www.bootitng.com ), even
if I don't have a need for multi-booting right now. Easier to deal w/ on a
clean system than dealing w/ *after*. It provides partition management,
boot manager, and backup/imaging, all in one package. If you have this
installed and available, it will make long term management of your PC much,
much easier. Just some friendly advice.

XP installs directly off the bootable CD and provides partition management
features, but I never do it that way. I use BootIt NG to build a 4-6GB
FAT32 partition, align it for NTFS conversion, add a menu item for that OS,
give it a one-time option to boot from next device (CD), boot it, and
install XP there. After XP is installed, I run convert.exe under XP if I
want NTFS (I usually do for the OS partition). When completed, I then
image the XP partition using BootIt NG and store it at the end of the HD.
Now I have a bootable, restorable, working image of the initial install
available to me at all times. So if I mess up further with installation, or
future drivers, I don't have to go through the entire XP install again! I
can also clone the XP installation whenever I want to experiment w/ new
software, have suspicions about new drivers, want to save a snapshot, etc.
I do this two or three times a month. Because I use this methodology, I've
disabled XP restore, it's useless. If I want *long* term protection of my
partitions, I use BootIt NG and image them to CD-R or DVD+-R media.

As far as drivers, XP is incredibly good, unless you have something truly
*new*, the OS is uncanny at finding and correctly configuring the PC, it's
really miles above any prior Windows OS. I used to have to take out PCI
cards and such under Win98, NT, etc., but this is rarely the case w/ XP.
Defaults drivers are rarely a problem, and I've had ZERO problems
configuring on-board audio, lan and other drivers I had to download from
Abit.

Regarding the OC...

Since you have PC3700 (230MHz), I would advise running sync (1:1) first,
thus underclocking memory (200MHz). Your only other option will be a 5:4
CPU/DRAM ration, which means you'll be underclocking memory (230 / 5 * 4 =
184 MHZ). PC2700 is only useful if you intend to OC the FSB, presumably
230MHz, but I'd advise against this initially. Keep it all 200Mhz (1:1).
Then when stability is acheived, and since we can assume the memory will run
230MHz, start slowly increasing the FSB, keeping the CPU/DRAM ratio (1:1).
This is likely to be successful, even *I* get 230MHz. If that's stable, now
you can start running above 230MHz (1:1) to see how far you can push the
FSB. Of course, your memory may hold you back at some point, perhaps VERY
soon. Memory above PC3200 often has a much smaller margin of
overclockability compared to PC3700, PC4000, and higher. You may be able to
relax timings and add vDIMM to get a little further, but w/ PC3700, you'll
probably top out at 240-250MHz FSB (1:1). Above 250MHz FSB (1:1), you;ll
probably have to switch to 5:4, provide additional cooling, more vCore, etc.
Of course, your memory suffers in the process, so it all boils down to how
much you can achieve above 250MHz to warrant the hit on memory. Of course,
don't count on 288MHz FSB (5:4) in hopes of bringing memory up to spec
(230), extremely unlikely.

If I had to speculate, you'll probably end up either running 230-240MHz 1:1,
and remote chance of 250 (1:1), depending on quality of memory, OR,
250-255MHz 5:4, if lucky. At that point, it's just a matter of benchmarking
the two and seeing which produces the best results.

I see your point. based on my experience with Corsair XMS3500, at 5:4 I was
able to do 244 FSB on a 2.8C CPU (IC7-G board) and with Corsair XMS4400, I
am able to do that same fsb with ram at 1:1, albeit slightly looser timings.

however, with your experience with being able to do 218 at 1:1, that sort of
indicates that the ram is not the limiter...

no way to adjust NB voltages without hardware mods, at least that I am aware
of. if the ram is async (5:4) and timings loose, you haven't tried to play
with PAT/GAT yet, and the ram is well rated to begin with, then you can
*assume* (careful, there... it is not always a safe assumption...) that the
ceiling you run up against is the CPU.

then you try to tighten the ram timings and in most cases, unless the ram is
something like the XMS4400 (or similar) Richard Hopkins was talking of, you
won't be able to do 1:1. so, again, you tighten the timings or try to
accomplish something with PAT/GAT. if really fast ram, then 1:1 with the
ram and more testing but timings are usually a little looser...

1.75 seems mighty aggressive to me for CPU core... tighten the ram timings
way up as a test to se if the system starts to fall over based on the ram
tweak... if not, that may tell you that you have some overhead in the ram
still available.

Hi Tom,

I'm not quite sure what tightening up the ram timings will do to help me
achieve a higher overclock, but as it running at 5:4 its only running 185MHz
(370DDR).

I just read something on HARD-OCP that says they couldn't get there test
board above 235MHz FSB until they took off the North-bridge HSF and
re-applied the thermal compound. Hmm I wonder if my northbridge HSF has the
same badly applied thermal-compound?. The northbridge HSF doesn't feel very
warm to the touch, I would expect it to be a little hot while running a
231Mhz FSB?

Anyway Prime95 is churning away, no errors yet after three hours so I will
leave it to run-in overnight and see how I get on tomorrow.

by tightening up the ram timings, I was only trying to suggest an indicator
of whether the ram is already at or near limits. if you can tighten the
timings with no ill effects, then that would indicate to me that the ram
still had some overhead...

Here's my stats:
RAM ratio = 5:4
P4C 2.6 @ 3.125
vcore = 1.55
HSF = stock
Goop = Arctic Silver
M/B = ABIT AI7
FSB = 240
Kingston HyperX PC3500
2x512Meg
timing = 2-3-3-7
ddrv = 2.6v (stock)
G.A.T. AAADD
P.S.U. = 400w Enermax
TEMPS: CPU NB PWM
IDLE 39 34 37
LOAD 61 39 56

or

RAM ratio = 1:1
P4C 2.6 @ 2.862
vcore = stock (1.525)
HSF = stock
Goop = Arctic Silver
M/B = ABIT AI7
FSB = 220
Kingston HyperX PC3500
2x512Meg
timing = 2-3-3-7
ddrv = 2.8v (Max Manufacturer spec)
G.A.T. AAADD
P.S.U. = 400w Enermax
TEMPS: CPU NB PWM
IDLE 37 33 35
LOAD 57 38 50

* extra case fan on top of M/B cpu pwr supply area helps alot

How much of a performance difference did you see by switching to a
1:1 ratio? Is the difference all in memory bandwidth? It sounds like
if you were running your PC3500 at a FSB of 244 with a ratio of 5:4,
you were underclocking it to 195, correct? How high did the PC3500
go at 1:1? So many questions...

With the ram at 1:1, I could not get anywhere near the 244 that I could run
at with the ram at 5:4 so I didn't do a lot of testing as I felt that
overall, the system was suffering from the lower FSB.

memory bandwidth went from 5159 with the XMS3500 to 5625 without any real
tuning (yet) by going to 1:1 with the XMS4400 and I will be trying to tweak
timings and such as time goes on... FSB remained unchanged between those
two tests. realizing that it is not a massive jump in bandwidth, it is
still not insignificant and Richard Hopkins has posted that he was able to
get the bandwidth numbers up in the 6000's.

I was just wondering about the capabilities of the Corsair PC3500
in the Intel setup. I have a couple sticks that are topping-out at 213
MHz on my NF7-S. I wonder if the chipsets or something else can
cause some of these boards to not run as fast.

my XMS3500 seemed to top out and I was unable to use 1:1 at anything above
stock FSB.

My stats then: :-)

*Processor*
P4 2.6C @ 3250
VCore at 1.7V (yeap.. high :-( )
T_idle about 30°C
T_stressed about 46°C
Cooled by Zalman WB2 (water...)

*Memory*
4*256 MB Corsair XMS 3000
runing at CAS 2.5/3/3/8
Ratio: 5:4 (200MHz)
V_DDR: 2.7 V
This scores about 5400 MB/sec Sandra buffered.

*Vid card*
Radeon 9500 non-Pro 128 MB
softmod to 9700
O/C to 380/321 with Swiftech MCW50 (water)

*PSU*
365Watt Enermax
active PFC

Hi TomG,

well surprise, surprise! I think you may be onto something here?. My
overclocks very *failing* when I used 5:4 memory ratio with *LOOSE* timings
(2-8-4-4), but I somehow discovered that by tightening the memory I am
making headway?

I don't understand that? how come with loose timings my Prime95 was failing
after a few minutes, but now I tightened the memory it seems to be working
well?

confused?

well, I have to admit that I thought that tightening the ram settings at a
given clock would only do either nothing at all, showing that the ram was
still "comfortable" and not the cause of any current instability, or help
the system fall over and demonstrate that you had pushed the ram out of the
envelope.

I did not expect that one of the results would be to improve performance...
