I think these are your two issues. For one, having a high ambient is going to yield higher temps. And since your HSF is a HDT cooler, it would be best to use two short lines as shown here.

well i been running this clock and voltages for 2 days now after the p95.....this is defiantly folding stable....what you think of the temps and the voltages?


i guess that doesnt show voltages....rofl....they are 1.3 idle, 1.324 under full load

Just upgrade to an 3820. Waited a couple days to make sure everything was good with my OS before I tried to OC.
Unfortunately due to a miss calculation in Newegg's inventory I didn't get PK-1 thermal paste. I'm using the stock stuff that came with my EVO.

My goal is to get to 4.6ghz as many have in the thread. (I've been reading from the beginning, at page 85 now.)
So far I'm trying the 125 BCLK with 37 Multiplier. Had to raise my voltage to 1.36 in bios. Stable so far (25min in P95.) with a top temp of 81c.

What settings for vtt do you recommend not going over and the LLC what should I set that to? I don't think I even changed that yet. The voltage droops down to 1.344 when stressing it.

Update: Sorry for long post.

My Intel 330 180gb SSD couldn't be accessed in the Intel SSD Toolbox. I was doing benchmarking trying to extract every last ounce of speed from my system. I then read about Intel C600 chipset drivers for the x79 board having issues. As with any software issue, if the time required to remedy the problem is estimated to be longer than full reinstall, do the latter. Long story shot, full reinstall, Windows 7 64bit, proper drivers, all 100%. I can access the tool box, cpu-z and coretemp are reporting correct cpu id.

At this point I'm benchmarking a score of 5,200 on passmark.com and ~5,800 on PCMark7. Right in line with other systems of similar specs. Here's where it gets weird.

All my overclocking specs were done by setting various modes/numbers in the bios, booting, and running Prime95 WITH (as Ive been told) SUM ERROR CHECKING AND ROUND OFF CHECKING enabled. I also do the custom test using 95% available memory (29,000megs). If it can pass for more than a few minutes, I refine my voltage and memory timings. Once Ive determined my voltages (manual mode) and ram timings. I ran prime for about 30-60minutes. All good. I ran Passmark about 30 times over night to get a good rounded score. Found here -> http://www.passmark.com/baselines/V8/display.php?id=2271957229. While this isn't a full stress test, it ran through the night with no issues.

This morning I shut down and left for work. When I returned the computer was running. I thought that was weird and found out windows was asking if it could force close open windows before shutting down. It was waiting for user input. I clicked shut down and off she went. I powered up a hour later and BSOD up the bum! Code 0x0000007E, which the forum tells me is Corrupt OS files. I call bull****. Shut down about 3 times, pull power cable, hold power button to kill all power, then reboot. Everything is fine??????? WTH! Ran sfc /scannow and found some errors but nothing major, chkdsk /r with no issues.

Don't get me wrong, in overclocking the system it BSOD'd about 40 times, going into the bios after each to refine and test.

At this point, I'm in windows prime95ing, and 5/8 threads crap out with fatal errors. IE: 2.5 of my 4.0 cores **** the bed. Prime95 continues to churn along. I cant get it to BSOD to tell me what the issue is. All 5 threads died within 12 minutes of prime95 running, the other threads went on for almost an hour no problem.

System is stable playing games and general usage. REMEMBER, I use SUM and ROUND OFF error checking in prime95.

I don't know where to start! Do I switch to offset voltage? Raise something, lower something? I just don't know.


RIGHT CLICK SAVE AS TO VIEW MY LARGE IMAGE PLEASE smile.gif

Forgive TurboEVO for report wrong voltages etc. I think it conflicts sometimes when you have multiple monitors voltages open.





Here are my bios screen captures.

llc extreme or ultra is a start
post #1786 of 6506
I ended up changed my settings to:
Vcore: 1.31
BCLK to 121.125
Multiplier to 38 which gives a 4.6ghz clock speed.
Ram is 1615mhz @1.5v
CPU PLL is 1.8125
Says cpu strap is at 125. I left it at auto.
LLC is set to ultra high with 130% I think.

It passed 13 hours of Prime 95 Small FFT. Got to max of 76c on core 0. Stayed mostly at 73-74 the whole night.
I stopped it so I could play a game.

Anything I should change or make better?
I might be able to lower the voltage one notch. 1.3v failed just after an hour.

I see the 121.125 bclk, but keeping it at 125 nets me a 5000mhz FSB which gets my benchmark scores higher.

  • Correctly apply TIM if you haven't already.
  • Buy some better TIM like the NH-T1.
  • I've had the NH -D14 for around 6 months now and it still hasn't grown on me. If i'd found a H100 cheaper than the NH - D14 or Phanteks at the time then I probably would have gone for it. If i had to choose again then I would choose the phanteks as they seem to perform better and is hands down the better looking of the two- http://www.xbitlabs.com/picture/?src=/images/coolers/silverstone-heligon-he01/zchart_table_big.png

I'll be needing the HT but not all the time. Though I don't want to turn it off then on again.
Will try to lower the voltages again but I remember when I increase (-) offset of 0.020 - 0.025, OS BSOD. Is there other setting that I should consider?
Just guessing maybe the thermal paste is not enough to touch the cores inside the SB-E die.
I'm already eyeing on Tuniq TX-4 paste.
Still positive with my coolermaster hyper evo that can do better.

Will post the result soon! Thanks!

Already considered this since I was using the exact same base with Xigmatek SD1283 on my previous Q6600.
But changed my mind when I saw different.



Thanks for bringing this up, Instead I will try to put 4 small lines on each pipes and see thumb.gif

XWhoo started ocing my new stuff. I'll definitely give more details but doing stability stuff right now and increasing the clock.

I LOVE my cooler , it's a thermalright true spirit 140

Current overclock:
4.2ghz, with 25-27 degrees C normal load, and 50 on prime 95 torture test load.
