680i SLI is too expensive? Asus as the solution : P5N32-E SLI PLUS

his cpu is at stock speed, it should definitely not need 1.5V

9x266, everythings stock, including Vcore. Auto in bios, 1.31v in PC Probe II

edit: OK, set all the default ram timings, upped a couple voltages (vtt, vcore)

try running ram or cpu by itself to see if you can isolate cpu or ram as the problem...if all fails, try prime 95!

Are you sure is not you CPU with problems?

My previous P5B Deluxe I used to get 3.4 with 1.57 Vcore. This board I get 3.6 with 1.60 Vcore, note that this CPU is a week 24, so it is the first batch of Coroes and what I can tell you people, this is the best board that I got so far. It is very stable. The P5B Deluxe used to get 1.63 bios and 1.57 so the V drop was about 0.05, with this board I do not get V drop at all, what I set in the bios I see right here in the monitor.Well maybe I'm just a lucky guy after all.

CPU is a week 32, retail. Lapped, think lapping could damage it? Or maybe not fitting the Tuniq tower correctly?

OK, restarted, set BIOS defaults.

Entered all RAM timings from the GSkill Tech
Set CPU VTT and NB to 1.25v and 1.35v
Everything else default, and its running fine so far

heres the 2 shots:

try using 1.38 vcore in the bios. I forgot you weren't OCing ignore my 1.50vcore comment earlier.

but what I think you should do is set a voltage for the top 6 things in the bios leave nothing on auto. use the voltage monitor to get an idea of what you set in the bios. most of all make sure your using bios 0602.

Cheers, for now, Vcore is at auto, and Orthos blend is 3 hours in.

Looking good but ill try 1.38 if this doesnt work.

Couple things, all voltages read by PC Probe are correct (measured by volt meter) except one, vDIMM is set at 2.375v in the bios, reported as 2.42v by PC Probe but is actually only 2.27v according to the volt meter, both at full load and idle. Weird.

Well, im'a head now and leave it on overnight. Will post results in the morning.

Crazy guy

Well I make my own assumptions about what is stable or not, Orthos is good but it does not tell you all. Well bit strange if you are not a programmer.

Well Orthos Small FFT's to stress CPU ran for 8 hours without fail.
Tried Orthos Blend, which lasted about 5 hours before i got a rounding error, i'll up the Vcore to 1.38 actual, not trusting PC Probe.

Also might up the vDimm a bit, since it seems to be about 0.1v out.

Cheers

EDIT: ok, raised vCore to 1.38v and vDimm to 2.45v, underclocked the cpu and the ram, and it fails Orthos after 5 seconds.

Argh.

Anyone know the vDimm read point, because either mine isnt right, or my vDimm is off, by a fair bit (0.2v)

BIOS: 2.25v
PC Probe: 2.29v
VoltMeter: 2.17v

BIOS: 2.375v
PC Probe: 2.41v
VoltMeter: 2.27v

BIOS: 2.45v
PC Probe: 2.50v
VoltMeter: 2.29v

[G.Foyle]

Any of you using Patriot 800MHz 4-4-4-12 2x1 GB LLK memory kit?
I have heard form a guy at local store that they won't work with most 680i boards, and they are not on ASUS QVL for any nForce 6x0 board...

raising voltages is the very last thing i do
putting too much voltage through your components will cause errors to appear as quickly as not enough

i only need around 2.1-2.2V for mem set in the bios to go from anywhere from 880 4-4-4 1T to 1000 4-4-4 2T to 1160 5-4-4 2T

Hmm I see. I was just raising the mem voltage a bit to see if the board possibly wasn't giving the ram enough power, as the vDimm point reads alot less than its set at. This ram is rated at 1066Mhz @ 2.4v so I didn't think 2.45v would bother it much.



Ok, the link you provided was a different vmem point, which reports 2.35v, when the BIOS is set to 2.45v, and PC Probe reads 2.50v.

[Pyr0]

strange, from what i've read, most people are finding these boards are overvolting memory, my board (non-plus) gives me approx 0.05V extra on the mem (measured with a meter)
does anybody else have any measured vdimm results for the plus boards? do they all undervolt?

have you tried tuning your memory timings yet?
try not to just rely on other peoples posted settings - g.skill tech included

[shimmishim]

well... i've gone from 11 hours orthos stable to 45 minutes then lockup orthos unstable.

my room temp has gone up about 5C's since I last tested and I have a feeling that the NB (though the stock one has been replaced) might be overheating.

i run blend test and it always locks up at 44-48 minutes, right when it transitions into the 896 length. hmm

[espionix]

Well i set vDimm to 2.35, and im reading 2.26v off the vDimm point.

I'll try messing with timings etc

[espionix]

I bear good news..




Saved all the BIOS settings, so I know what should be stable then.

Only thing underclocked was ram, running at 800Mhz instead of its rated 1066Mhz.

Note: 2.35v in the BIOS supplies 2.27v actual, not 2.4v like PC Probe Reports.

[Jultsu]

My board has now died. GODDAMMIT! Wont post, no matter what i do. I was feeding 2.4v @ memory 24/7 so maybe... http://www.evga.com/articles/350.asp ?

I am so goddamned pissed right about now. Hopefully I'll get a stick of DDR2 to test if the board or just the memory is broken.

[Jultsu]

Well...it was the RAM. I got some DDR2 533MHz sticks from a friend and the board booted happily. So kids, don't NEVER EVER feed 2.3+ volts 24/7

[espionix]

What are you kits actually rated at though? And did you measure what 2.4V was actually supplying with a volt meter?

[Jultsu]

Memory was rated at 2.1 - 2.3, and setting 2.35 in BIOS would turn out 2.40 in windows (measured with Everest ultimate)

[The Viper]

heh anyone know if I am suppose to enable something to run SLI on this board, just tried with my 7900gts, and was unable to do so, theres no option in the nvidia menu to enable SLI, IM going to tyry a different set of drivers

EDIT: Nevermind, I figured it out...I dont think the drivers I was using supported SLI

[safan80]

well... i've gone from 11 hours orthos stable to 45 minutes then lockup orthos unstable.

my room temp has gone up about 5C's since I last tested and I have a feeling that the NB (though the stock one has been replaced) might be overheating.

my system is orthos stable @ 3.6Ghz with the room temp at 30C. My NB has watercooling plus a 120MM fan over it. do not let the NB get above 39C.

[The Viper]

Can someone tell me where to measure the actual CPU and mem voltage with a volt meter?
