Overclocking 1900+ on K7S5A Pro

[Guest]

Archived from groups: alt.comp.hardware.overclocking.amd (More info?)

Has anyone had any experience overclocking a Palomino core Athlon XP
1900+ on ECS's K7S5A Pro mainboard? I purchased both from NewEgg.com
just before christmas, and recently flashed the latest CheapoMan BIOS.
I can currently overclcock to a 2100+ by adjusting the FSB to
143/143, but at this speed stability is a severe problem (only half of
my RAM is recognized on most boots, requiring a restart, even with my
timings set very conservatively). Here are my specs:

ECS K7S5A Pro (rev. 5)
Athlon XP 1900+ (Palomino Core)
128MB of PNY Optima PC-133 SDRAM
Seagate Barracuda 80GB ATA-100 hard drive
ATI Radeon 9000 (AGP 4x)
Creative Labs Soundblaster PCI 128 (in PCI slot 2)

Any advice would be strongly appreciated.
Thank you,
-Hukuis

You can either unlock the cpu by closing the L1 bridges and then use the
pin mod to set a higher multiplier, or you can just change the default
multiplier on the cpu. You may also need to raise vcore. This can be done
with the pinmod, or by changing the default on the cpu. You will probably
max this cpu out at ~1800MHz up from the default of 1600Mhz, for an
increase of about 12%, so you can come to your own conclusion if the
effort is worth it. See link below. Personally, I'd just get a new cpu for
it and not waste the time for that little of a gain. Any /266 model should
work in it well, with a 2400+ probably being the best bang for the buck.

Palomino cores dont overclock very well at all, my old 2.1 palo would only
just about manage to get to around 2.2 ghz even then it didnt like it one
bit.

Since there is no 2.1 Palomino core, can we assume you mean a 2100+ model
that has a default speed of 1733MHz, and that you really mean you got it
overclocked to 2200+ speeds (1800MHz) instead of a true 2.2GHz?

Yes sorry I should of been more clear with the statement, I was posting as I
was going out for the night. You would need to conduct that OC at absolute
zero to get a 2100+ XP to run at 2.2ghz core clock : P

What is the best solution to use to connect the L1 bridges? Would
white-out work to fill the gap and then use a pencil to connect the
bridges? Do you know of anywhere i could buy a conductive pen?

I am looking for any performance gain i can get ahold of... I am still
in high school and have no job to provide for an upgrade, even one of
only $83 for a thorton core 2400+. Does anyone know where the 1/5 PCI
divider kicks in for FSB on this board?
thanks for your help everybody

Fill in the laser cuts, make a bridge with conductive paint.

Hmmm... White out might work, but the pencil probably wouldn't (too much
resistance).

Auto parts tore for rear window defoger repair kit usually has conductive
paint. Try yahoo shooping or whatever.

Do I need to unlock the L1 bridges to use the pinmod? OCInside.de
didn't mention it, but maybe it was supposed to go without saying.
What vcore do you think i should use to gain a 1.8 gHz clock? And does
anyone know if there is a way to get the PCI divider set to 1/5, and
if this might help me gain a higher clock speed? All your help so far
has been very useful.
Thanks everyone,

Yes

Hard to say. Might work at default 1.75 or may need 1.85.

I think there is a way, but I don't recall the details, other than it had
to be done after boot or something. It only took a few seconds with a
google search for k7s5a divider to find a lot, this was the first. There's
lots more.

Q1: So what is Chfsb?

A: The official ECS bios releases for the k7s5a only allow the standard 100
and 133 MHz front system bus (fsb) settings. Some time ago a few beta bioses
which included several additional fsb settings were leaked. These are known
as the "overclocking" or "OC" bioses. The programming for the extra fsb
options is still present in the newer official bioses, but they were removed
from the bios menu. Chfsb is a little program that makes it possible to use
these extra fsb settings with all bios versions. You can download it here.


Q2: Which are these extra settings?

A: Currently Chfsb supports frequencies of 112/112, 124/124, 138/138,
150/150 and 166/166 (fsb/memory), in addition to the official ones: 100/100,
100/133 and 133/133.

I have the CheapoMan BIOS which supports the following FSB options:
100/100, 100/133, 112/112, 124/124, 133/133, 133/100, 138/138,
143/143, 147/147, 150/150, 166/133, and 166/166

What I am searching for is a way to make the PCI clock be generated as
the FSB divided by 5 instead of the FSB divided by four. This might
allow me to overclock to a higher FSB. Also, what are the risks
associated with using the pinmod in lieu of BIOS multiplier settings?
If I set my multiplier too high will it fry my CPU? Or will it simply
not boot until I change the pin settings? Thanks a lot guys.

The 166/xxx settings would be worthless with a 4 divider. I doubt you'll
find any PCI/AGP components that will reliably work on 41.6/83.2 pci/agp
buses. My guess is that at the 166 settings, the buses are within a
resonable limit. I'm not sure how the SIS chipset handles pci/agp speeds,
since I have never seen a divider setting in any, but I know I've run a
sis 746fx chipset at 215MHz FSB without a problem when it is only rated
for 166MHz. I read somewhere that the pCI goes up until it gets half way
to the next setting then starts over with a 30MHz pci bus amd reaches the
nominal speed at the next 33Mhz increment of the FSB. As I siad, I've run
from at about all settings between 166 and 215Mhz without a problem, never
worrying aobut the divider since there was no setting for it.

The pinmod won't work unless you have an unlocked cpu. The 1900+ came in 3
models. The original Palomino core is locked and would need the L1 bridges
closed before the pinmod would work. If you want to try 166MHz FSB with
it, I'd set the multiplier to 9-10 to start with after you've unlocked it.
A tbred A core should work at 10x166 & 1.65v easily, and a B core should
work at 13x166 at 1.65v vcore fairly easily. I don't think you have any
multiplier settings on the K7S5A board.

Right, but I was wondering if using the pinmod would create any extra
risk that isn't involved in overclocking using a BIOS setting. I know
on my friend's board with an nForce-2 chipset when the settings for
multiplier and FSB are too high, it will refuse to boot. Will my
processor function in the same way using the pinmod, or was this a
special BIOS feature on the nForce-2? As i said in a previous post, I
am still in school and have no job, making it impossible for me to
simply upgrade. I don't want to have to replace a fried processor and
have to be without a computer until I have enough to buy a new CPU.
Thanks for the tips on PCI/AGP dividers, they really helped a lot.
Thanks,
-Hukuis

There's always the posssibilty of screwing something up, but the chances
of screwing up the cpu by raising the multiplier via the pinmod is no more
than doing it with a bios setting. IOW's, it's possibly, to blow it with
the bios too, but not likely in either case. As long as you know what you
have and stay within reasonable limits, there shouldn't be a problem.

Thanks for the help, but I'm just about at my wit's end. Does anyone
know where I can get a cheap T-Bred 1700+? I have heard stories about
overclocks faster than 2.2 gHz on these processors. This would almost
certainly be easier than working with what I've got. How much do you
think I could sell my 1900+ for at a swap meet or on eBay?
Thanks guys,

Just a note. It will have to be a Tbred B cire 1700+ to go over 2G, the
original A core won't do it. And it doesn't have to be 1700+. ANY Tbred B
core will work. The one below was is a 2100+. And you will need an
unlocked one and the pinmod (to change multiplier) with your board.

What is the cheapest T-Bred B core processor I can buy? And how much
do you think my 1900+ would fetch on eBay or at a swap meet?

Check prices on ebay. Last time I looked I found a couple of B core
2100+'s for about $20. You'll get at least 10-20 for the 1700+ if you
provide good info about it.

$20 is well within my price range, but are there any others that are
cheaper and would provide similar results? And I assume you mean
$10-20 for my 1900+ that I'm selling?

Yes. IOW's the final out of pocket would be less than $20.

Best way is to view the CPUID in software. That's definitive. 680=A 681=B.
If going by the stepping code, it Should end with a B as the last
character, as in AIUHB. This may not be definitive, but I don't think
they've found one that ended in B not to be a Tbred B, although there are
B cores that end in A also in the 2400+ and above range. there may be some
Palomino cores that end in B (I don't know), but the part number for them
would start AX<model number>ertc. while all Tbreds are AXDA<model
number>etc.
