Also...I don't think I did a very good job mounting the TRUE. Usually I do it 2-3 times to get the temps really nice, but I was lazy and didn't do that lol.

What's your ambient temp? That could explain the differences as well, and what Prime 95 test were you using? Blend or Small FFTs?
Blend. As for ambient temp... I don't know honestly. Probably somewhere around 70F.

Ah ok, quite a bit cooler than my ambient. Also, Small FFTs is what I was using and it gets it a bit hotter than blend.

One more thing. Do you have HT turned on or off? Having it off makes temps drop a lot.

HT is on.

Just finished my overclocking , will lower my QPI/DRAM voltage a bit more , but i'm currently stable at
4Ghz 200x20 HT off
Ram @ 1600 with 9-9-9-24 T1 timings

vCore 1.225V
QPI/DRAM 1.2875V
NB(IOH) 1.16V
DRAM 1.65V

Rest @ lowest possible voltage.

Case temp // 23C by speedfan
Load temps using LinX is maxed @ 67 / 66 / 64 / 61 using realtemp

Going to lower my QPI/DRAM some more and test stability.

Hi,

Just got my D0 a couple days ago, and since it's been great! I'm @ 4.01Ghz. 4 hours prime 95 stable, 4 hours small fft Orthos stable, and one hour OCCT stable. 201 X 20 and my max temp is 69c with HT off. My problem is whenever I put them computer to sleep it wont wake up. I press the button and the fans run, but that's it. It used to work just fine before the 4Ghz, but now I am not sure what to do with it. I use this feature a lot and would really like to get it going again. Any thoughts on where I've gone wrong? Thanks!

I believe this is an issue on the Deluxe that simply won't be fixed. Which is why they somply released different versions. I believe you can cross flash your BIOS if it really bugs you.

Also, make sure any power saving options and speedstep is disabled.

Robilar,
I've got the same setup as you and I'm going to be trying my hand at overclocking for the first time. What are your current settings in BIOS? My goal is to get to 4Ghz stable on air.
Thanks man!

I finally got mine up and running again.

This is my overclock so far :

I am 24/7 stable on OCCT Small, OCCT Large, and OCCT 64-bit Linpack 90% Free Memory. I ran 4 passes of MemTest86+. There is a discrepancy between my memory/timings and QPI/NB speeds shown in the verification because my real RAM is being RMA'd as it was apart of that world-wide recall. So I am using my friends crappier RAM until I get my stuff back, I'll do another verification when I get my good RAM back!

CPU 210x21 = 4400MHz
RAM 210x8 = 1680MHz (7-7-7-20)
NB 210x19 = 3990MHz
QPI 210x18 = 3780MHz (7.56 GT/s)

Motherboard: X58 Classified
Batch#: 3849B041
**VCore: 1406mv
**VTT: 1400mv
**DRAM: 1530mv
Cooling: Water, (CPU + Chipset)

All other voltages at Stock. The DRAM is at stock but my mobo puts it about 30mv higher than it's setting of "1.5v". Both my VTT and VCore are set to 1.4, however the VCore measures 1.406 under load. The BIOS reports my VTT being 1.49v, which is a lot higher than it really is.

**(measured with mutli-meter under full load 0.5% +/- accuracy)

My temps are 72c during Linpack, and 65c during OCCT. My VREG's are pretty cool and stay around 50-55c depending on load. I live in an non-air conditioned dorm room with higher than normal ambient temps in the summer.
