ASUS P5N-E SLI 650i Thread

[Pumpkinhead]

MY FSB was at 1500 at the time.
My voltages were default.

Vcore1: 1.44v
Vcore2: 3.34v >>is this the MB voltage ?

Also , how much is a notch ? .100 V ?

I meant 1 step up, which I believe is .00625v.

And no that is not your nb voltage. In the bios you should set it to 1.39. 1500 is close enough to 1600 that it may need a little extra juice. But first try with the extra vcore.

edit: Wait, you have the vcore on auto?

Could I perhaps get a bit of help? :S

Start by setting your voltage manually for the cpu. You can use cpu-z to get an idea of where to start.
Then start raising the fsb in increments of 10.
If you become unstable raise the vcore a notch or two. You should test with orthos smallffts every few raises for 10min.
I would set the fsb to unlinked so you can oc the cpu individually of the ram.

edit: oh and disable energy saving features, and watch your temperatures as you raise the vcore.
edit2: also manually set the ram timings for extra stability

Now the Vcore is set 1 set up ( +.00625 ) to =1.406325v
it was =Auto.

currently....
the Memory V = auto
NB Core= Auto
Vcore Offset = Auto

Orthos is running now. CPU temps in the 52-54c range.
CPUz reading 3.0GHZ! I am keeping my eye on it.....

Should I keep these other voltages to AUTO ?

The others should stay on auto unless your ram needs more than 1.8v at stock. If you are unstable at 3ghz at your current setting, bump the vcore a little more. But if at 1.42 volts it is not stable then you should start to toy with the nb voltage. If it comes to that, try 1.39v first, and if that doesn't fix it you are going to need better cooling to go to the next voltage (1.56 iirc). At the least you should reseat the stock cooler with good tim.

Does anyone know the southbridge hole to hole distance?
Ive looked at several nb/sb heatsinks, but they have different h2h distances.
Im wanting to buy this enzotech CNB-S1L, that i can use with SLi since its low profile. the hole to hole distances are 54.6mm and 59mm, so could i use this with my P5n-E sli?

Another "Help, I'm new" question.

System specs:
E6600 B2 stepping (2.4GHz 1066FSB stock)
ASUS P5N-E
2 1GB Patriot Extreme PC-6400 4-4-4-12
EVGA 8800GTS 640 MB (G80, sadly)
Antec SLK-2650 with a Noctua 120mm 1200 and a jury-rigged 120mm fan on low voltage near (but not in) the front intake.
Jury-rigged ducting to isolate side vent to pull directly onto the stock CPU heatsink and separate the PS fan from the rear exhaust fan (the PS was pulling so hard it was reversing airflow through the rear case exhaust). Tested and this ducting does lower case, GPU and CPU temps.

Read through the various stickies (Intel chipsets, the P5N-E guide, and the temp guide).

Trouble with temperatures, which make me reluctant to up the Vcore any further as I OC.

Stock settings (auto everything except memory timings), Prime95 25.6 large FFT: core0 56C, core1: 56C, and what as far as I can tell is Tcase: 44C, ambient temp around 25C.

Re-seated the processor and the NB heatsinks with Arctic Cooling MX-2.

Running at 1600FSB (8x multiplier for 3.2 GHz), unlinked memory (1:1 ratio), 1.306 Vcore, 1.56V NB, 5xLTD, and everything I don't need disabled. Fails Prime95 small FFT after about four hours, oddly enough always on the core1 thread.

Idle temps at 1600:
Tcase: 43C
MB: 48C (figure this is due to the GPU never getting below 60C)
Core0: 50C
Core1: 52C
GPU: 64C
and just for comparison's sake:
HDD: 43C and 38C

Prime95 small FFT temps at 1600:
Tcase: 54C
MB: 48C (figure this is due to the GPU never getting below 60C)
Core0: 69C
Core1: 69C
GPU: 64C
HDD: 43C and 38C

From all reports, I should be able to run at 400x8 on this CPU/board set easily, and certainly not at the temperatures I'm seeing.

My next steps are to try a proper 80mm fan in the front intake to see if that improves the circulation and an old 50mm CPU fan on the NB, but the noise level's starting to get to me. If that doesn't work I'm considering cutting the grill out of the front intake (it's pretty thick).

While I'm disassembling my computer, any thoughts, ideas, warnings?

You need more vcore. Your nb voltage is plenty, I hope you have adequate cooling on it.
However, your temps are very high on the processor; try reseating the cooler, and possibly use less tim.

Have a 50mm fan sitting on it, pulling air off the northbridge and pushing it into the path of the case exhaust fan.

Oddity I noticed just now with my core temps, where under Prime95 they'd read 69-70C, but as soon as the program stopped they dropped to 59-60C. Not over a few seconds where the decline is noted, but from high to low with no stop in between, within less than a second. I'm rather surprised to think the temp climb can be watched, but not the decline -- slapping ice on burn doesn't cool that quickly.
