Plus I've read some posts here and at xtremesystems.org forums indicating some folks have better stability with lower vdimm.

So I made the ONE change to lower vDimm from 2.2 to 2.0 and I was stable in orthos small FFTs for over 7 hours - it's still running as I type this. This is with RAM at 800 MHz via Auto, Sync in BIOS.

Max temp I saw was 60c in the cores using Speedfan 4.32 with a +15 offset. This occurred periodically over the night, but the nominal temp seems to be 56-58c.
Good,now jump to the next step.this chip can run stable @ differents OC.Try my settings and report back.
Those settings are for 3.7 stable.

Hi
I am looking for a new board (my P5N-E have burn out).

Could anyone tell me shortly, how good/bad that mobo accepts voltages for CPU as 1.6 and up? is there a big Vdroop. And what about 1T timings for mem (last mb did only up to 840 Mhz). Is it very selective about the ram? Normaly, how high the FSb goes?
Anyhing else I should take under consideration exepts cooling - I'll have it changed anyway.

1.6 volt's for cpu ,if you have phase or a cascade no problem.But 24/7@1.6 volt's no a good idea.

that mobo would be only for benching - not to run 24/7

Revisiting case fans for a brief moment, has anyone come across any 120mm that are very low-profile (thin)?

When I installed my CM Aquagate, I had to take two fans out because of clearance issues with the radiator. I'm having problems finding dimensions of most fans online. If anyone has experience with thin ones, I'd love to hear about it.

Cheers,

you can do 1.6v 24/7 with water cooling and your ambient is relatively cold... although I wouldn't advise it... but it's possible. I see people do it all the time. This board has a relatively bearable vdroop, if ur on dual-core.

43C is low, don't worry until you hit the high 50s. up cpu vtt to 1.55 (max). You may need to up vcore slightly more as well.

With the E6750, leave the multi at 8x, and try running at 400 (which will give you 3.6). After that raise it in small increments.
OK I Im running 3.6, orthos stable for 8hours and 12 minuts..

I raised the cpu vtt to 1.5 and the vcore to 1.45 all other settings are the same. So far so good,, Thanks man! 48c avg, at full load running orthos jumped to 51 for a sec or to.

And its 450 x 8 is 3.6, 400x 8 is 3.2

treatment x . with Q6600 G0 it's possible go under the 365 fsb on p5n32-e sli ?
post #2539 of 5659
Yea, i think it's an accepted theory that GTL Ref Voltage has been pretty variable, pretty 0.3-0.5v, and that quad clocking has varied between 350-380FSB, I topped out at 375, but I run 24/7 at 363.5FSB.

First post here. I assume my system details will appear below. I am using a CM Stacker 830 and I have temperature problems. When I close the case the CPU temp rises 10+ °C, but the MB temp cools by 4-5°C. My CPU cooler is a Noctua with two fans in addition to the rear case fan for a total of 3 120mm Noctua fans speeding the airflow through the cooler out the back of the case.

Right now I have a stable system at 3.3GHz. RAM is at 1066/5-5-5-15-2T, CPU idles at 40°C, MB at 43°C. When I close the case CPU temp rise to 50°C and MB cools to about 38°C. I expect some differences, but the CPU heats up a lot. When I run Orthos now the CPU will max out around 70°C !! These numbers are read at room temperature ~25°C

I use ProbeII, CPU-Z, Core Temp and NVMonitor to read values. Seems NVMonitor only reports nominal voltages. Can I trust these apps? I am using all the latest drivers, nTune etc., but my BIOS is 1002.

Take a look at the images of my rig. Aren't my temperatures very high? I tried remounting the cooler, using arctic silver 5 paste thingy spreading even thin layer as I have done many times with excellent results. Screws are as tight as they can be.
