Since I don't have that board I can only say the bios setup should be the same.

Your Northbridge cooling is not as effective. So if you increase the "NB voltage to 1.4V" you might have heat issues. If you could put a fan on it would probably work out. Hopefully there might already be someone out there who has tried it and can give you a better answer.

Nice overclock considering you haven't even raised your voltage much. Your setup has a lot of potential  

Now running my E6400 at 362.5 x 8 = 2.9GHz,
with CPU temps of 46c/45c @stock voltages, though
I've loosened the timings to CAS 5 (5,5,5,15,2T).
Smooth, fast, quiet!

Two questions for you iluv2fly;

Can you monitor your voltages and temps in Windows?
My mobo doesn't report any sensor(s) other than the temps shown in CoreTemp.
I've tried SpeedFan, nTune, and RivaTuner with no luck.
DualCoreCenter won't run at all for some reason.

Second question, what do you luv to fly?
I'm a 6000hr pilot, mostly helicopter (Huey/Blackhawk/OH-58/MH-6),
though I do have a few SE/ME/IP Airplane hours as well.

Blue skys!

TonyB.

your settings state-

System Clock Mode Manual
FSB Clock (in my case, 1460mhz)
Mem Clock (in my case, 800mhz) pc-6400
CPU ratio (in my case, 9 ) E4300 cpu

How do you determine your effective core speed?
It looks to me like you have 2920MHz (9x324.4), instead
of 3333MHz. Isn't the CPU speed 2x the FSB? eg. 2 x 1460 = 2920.
(Host bus*CPU ratio=CPU Speed)
What am I missing here?

Temperature monitoring software

Google the following software

"Core temp 0.95"

"Intel thermal analysis tool"

"PC Wizard 2007"

"Speedfan"

There are more of course.

The temperature can be read several different ways. By the motherboard, software estimated or on the cpu it self. On top of that different programs use different ways of calculating temperature. Some measure directly inside the cpu (Digital Thermal Sensor). Some estimates the cpu case temperature. And some uses motherboard sensors. That is why you will see different temperatures using different programs. Which one is correct is up to debate!

Google "ClockGen" to check bus speed.

It is going to be very interesting to see what the new E4400 can do when it is released. It has a 10X multiplier.

If the E4300 will do:

CLOCK=(1460/4)x9
CLOCK=(365)x9
CLOCK=3285mhz

Then the E4400 will do:

CLOCK=(1460/4)x10
CLOCK=(365)x10
CLOCK=3650mhz

with the same settings.

The rumors are saying that Intel will lower their prices April 22. AMD's price cuts are coming April 9. So Intel might cut their prices sooner.

Just failed to boot to BIOS setup with the following:

E6400
FSB clock mode: Manual
FSB clock: 1600
Memory clock: 800
CPU ratio: 8

DRAM settings: 5.0-5-5-15-2T

CPU: 0.0125v* Is this 'additional voltage' or desired voltage;
ie. 1.296 + o.125v = 1.421v .OR. 0.0125v total??
NB: 1.25 (default)
SB: 1.5 (default)
FSB VTT: +4%

Currently back at 2666.7 (333.3X8) 1:1.

Any suggestions? RE oc'ing that is! :wink:

TB

U need to give it more voltage. Try 0.05v. Correction to your math below:

"CPU: 0.0125v* Is this 'additional voltage' or desired voltage;
ie. 1.296 + o.125v = 1.421v .OR. 0.0125v total?? "

1.296v + 0.0125v = 1.3085v yes, total

I needed to add more voltage (0.05v worked) to move past 2.8 Ghz (1400 fsb), now at 1500.

Now cool AND fast at 2.66GHz/1333MHz FSB/5:6 800DDR!

hello everyone!
i have a p6n sli platinum borad as well :wink:
my current specs:
e6400 2.13 oc'd @ 3.0 ghz 1.34v
1500mhz fsb
2-gigs corsair xms2 675mhz oc'd @ 750 mhz (5-5-5-15) 2.1v
1:1 mem/fsb ratio

this current setup i have runs perfectly stable for me!
i have tried to raise the fsb higher than 1500 mhz and i am unable to boot :?
i noticed flyer has had this issue, has anyone else? i am wondering if this is due to limitations of the mb? it shouldn't be a heat issue. the cores are at 45c-47c (~25c ambient/monitored with speedfan) using TAT @ 100% which should be well within the thermal capacity of this chip. i've also tried increasing the vcore to no avail.

there's a good thread with a bunch of links at the [H]ardForums concerning all things MSI P6N Platinum

http://hardforum.com/showthread.php?t=1164174

thanks bud  

Awsome Link!  

Good news gentlemen! There is a light at the end of the tunnel  

There is definately a fsb 'hole' around 400mhz fsb! Mine seems to range between ~376 and 420mhz. You must go beyond this 'hole' to achieve more than 3ghz OC. It is also VERY important to maintain a 1:1 ram/fsb ratio at the higher OC's or it wont be stable at all!
I'm currently running voltages on the high side to ensure stability.

Try setting your SB to 1.6v... this might let you drop that high vCore down some at your current FSB, or allow you to crank the FSB higher.

My stable settings at 3.0GHz with the E6400 were:

FSB: 375 x 4 = 1500
Mem: 375 x 2 = 750
Mult: 8x
vCore: +0.0625 (<--- !!)
vNB: 1.35v
vSB: 1.6v
VTT: 4%

...I also bumped my memory up to 1.95v (normally runs at 1.9v), but I'm not sure if I had to do that or not (I was running the memory pretty loose at the time, just to take it out of the equation).

Another person used very similar settings to the above, but with the SB still at 1.5v and he had to bump vCore up by twice as much as me (+0.1250) to get stable.

We both also ran into problems higher than 375 (up to at least 400), so thanks for the info on finding the other side  .

Hmmm.. (re)reading a few of the posts higher up, it sounds like some of you were using even less of a vCore bump than me at 3.0GHz... so I guess there's some variation (you may have had different NB values, etc).

yeah spanki...mine were a bit different than yours at 3ghz (i have the e6400 too)
i bumped the cpu up .025v
nb was set at 1.3v
sb was at 1.5
i am running my mem at 2.0v (mushkin extreme ddr2 800 4.4.3.10) set at 750mhz for 1:1
vtt at 2%

i am currently able to run the cpu stable up to 3.56ghz 1780mhz fsb
at the same voltage settings i tried at 3.44 ghz.
i seem to have hit another wall at 3.6 ghz 1800fsb...TBC...
p.s. i turned the AC on (~72F) and its just touching 50C at 100% load  

manged to get up to 450 fsb and 3.6ghz on my e6400!
i ended up rasing the sb to 1.6 to stabilize and bumpd the vcore up to +.200

i noticed whan i bumped up my sb to 1.6v speedfan showed my vram being incredibly high?? i dont know whether speedfan was reading properly. i didn't want to fry my memory so i reduced the sb to 1.5v making the 450fsb clock unstable and reverted back to 430fsb....
if anyone can help a brutha out it would be greatly appreciated TIA!

Snagged one of the new E6420 processors, and am happy with it on my MSI board. I can't seem to get it past 3.4GHz, but it looks to be quite stable at 3.4, and that's not too shabby - a 60% overclock! Some people on other message boards had questions as to whether it would retain OC capabilities with the larger cache over the E6400, and it would appear so.

I have it at +.100V, and it's running cool with my Cooler Master HyperTX unit (with Arctic Silver 5) on it; CoreTemp reports it at about 20C idle, 45 - 50C during peak ORTHOS Blend stressing.

Memory is doing well, also - I have G.Skill 2G PC6400 rated at 4-4-4-12, and I have it testing great at 850MHz (FSB 425, 1:1), 4-4-4-10 2T at 1.95V. PCMark05 score on the system is 8311.   3DMark05 score is not quite as nice, at 7502, because I only have a GeForce 7600GT card.

All in all, I'm loving the P6N SLI Platinum board. This system fired up beautifully on first power button - the rest has just been playing with it! :wink:

what kind of temps are you getting?

....using TAT idle 42-44.....full load 52-56 degree celsius ....i,m using this set up playing games for 2-3 hrs

is this using tat to run full load? and did you raise any voltages?
as a general rule of thumb, the goal is to stay below 60c...can you post your specs hardware/bios?

nice lookin rig bud!
you should be fine with those temps (although Iwouldn't run it much more than 10c higher than what you're getting at full load)... thats not too high of an oc for that chip...its even better that you can run that at stock voltages! that'll keep your temps down. if you want to go higher, i'd suggest getting a better cooler for your cpu. i hear thermaltake makes a nice air cooler, although i'm a fan of liquid cooling myself :wink:
*note*installing the northbridge fan really helps cool off that triple heatsink ALOT
..btw, your idle seems a little high though, what kind of case cooling setup do you have?

.....by the way i'm using icute atx 9 not aluminum)...this case have a 250mm fan on side and 120mm fan on front..both intake..and for may exhaust i have a 120mm located on the rear and my power supply dual fan.

....for my video card i oc it to 600/920 settings using rivatuner..

.....do you think thermalright ultra 120 fits on our board?

.....during summer here in my country it reaches 36 deg. celsius upt 40 deg. celsius i think...very hhhoooottttt.....lol

that's freakin hot!!!
you probably can't do much about your ambient temp then...

i was reading some other posts on another forum that said the thermalright fits ok, so you should be alright. it looks like it has a pad in the middle of the back support to help it clear the electronics on the back.

HELP!!!

I can't get to anything above 3.0 without being unstable

I've tried the following;

NB - 1.5 - 1.5
SB - 1.5 - 1.7
CPU 1720 clock, 1600 clock, 1604 clock @ 8 and 6
(I'm unable to get to 3.2 without going to 6, and it's still unstable).

RAM - 750 @ 1500 - 800 @ 1600 - 860 @ 1720
Ram is set for 1.9v and 5-5-5-12 (Corsair XMS2)

I set my vcore +0.1, 0.0750, 0.150 and everything in between (won't be stable at 3.2 (my goal)

I've set VTT @ 2%,4% and 6% and still untable.

Any ideas?

Other than my VTT problem(having to be at +16% to be stable), I cannot seem to link my memory and be stable. Everything I have read says 1:1 ratio is the best for stability, but I can run 3.0ghz and 333mhz memory and I'll fail prime95 after a few hours. Put the memory at factory 400mhz and it is rock solid. I tried this on the 3.2 overclock as well, linked up the memory and actually had my pc reboot after 30mins. I've run memtest for 4+hours without a single error so I'm really lost with whats up with my memory and it being linked causing stability issues.

Initially I couldn't get into windows at all with OCing to 3ghz. It would post but not boot into windows xp. Bumping the FSB VTT to 2% allowed it to boot up all the way but BSOD after a few hours. 4% on the VTT same thing only longer before BSODs, 6% same.

Bumped the NB volts up one notch with the VTT at 6% and it all seems stable now. I also noticed that the BIOS was running the mem volts at 1.8 when my memory is rated at 1.9 so I adjusted that as well to reflect that.

Ran Prime 95 for 12+ hrs over 3 different tests and all were stable. I'll try a longer prime 95 test with large FFTs to make sure it is truly stable.

This is an incredible source of info for me, the complete noob overclocker. I have a P6N Platinum with a E6600 C2Duo 2 gig of G-Skill DDR2 800 RAM in 2 5-5-5-15 1t OC'd to 4-4-4-12 1t sticks, 2X 8800 GTS 640 cards in SLI, an Antec case with about 5 or 6 fans in it. Stock cooling. I am planning on OCing manually for the first time. I tried it a bit last night and screwed the system by trying to set my FSB to 1600 from 1333 in the Cell menu. Four reboots and I was back in business. I didn't know anything about unlocking that option in the CPU section of the bios so I am looking forward to trying that out. Going to be trying to set the voltages up a bit as well on the southbridge as well as the VT. Thanks again for such good info.

Hi all.

Well I own a P6N SLi Platinum like all the others here, but I believe to run a different system then most of you.
I´m running Mac Leopard OS X on my computer, and after following the steps to overclock my PC Leopard is always giving kernel panics and my computer hangs and I need to restart.

Does anybody here runs the same OS than mine or have any tips for me to make the overclock works like a charm??

Cheers.
