here guys 12 hours os prime and very stable very low voltage and temps smile.gif , I used to have 8 Yate loons in my loop and i decide to replace every fan for a new Cougar Vortex fans even the 140mm 360 still in push pull configuration and the 240 only in push but i had fliped my rad facing to side panel

This is the kind of overclock I like to see. Proven stable screenshot with low voltage. Some of you guys are posting 1 minute prime temps on what could be really shoddy overclocks.
post #1963 of 6606
So I have been at 4.4 stable for months using:

fixed voltage @ 1.34v
load shows 1.33v
LLC 3
PPL - Auto (1.79v)

I tried switching to offset voltage and overclock to 4.6:

Tried offset +.005, +.010, +.015, and +.02
LLC 3
Voltage showed up to 1.36v

it always eventually crashed with the BSOD error code 124. Any ideas on what other settings to adjust or do I just keep increasing the offset (raise vcore)?

Thanks

You can post up your bios screen shots for us to take a look at. How long did P95 run before it crashed?

124 is stating vcore/VTT. The BSOD list is on the first page

Would you like the BIOS pics of my offset attempts? Also, I just ran folding@home as my test. It appeared to last a few minutes longer with each voltage increase/offset bump with the last one lasting for more than 2 hours. I'm running with an Antec h20 620 and my temps never got above 61C even at 1.36v

I'm at work now but I can post them when I get back. Any initial thoughts?

You can just post screen shots of your current bios setting so everyone can take a look. You probably just need a higher offset

I finally got around to doing a more than sufficient P95 run with my overclock. I stopped at 34 hrs at 4.8. Temps maxed out at 82 C and typical voltage was at 1.328 although it appears to have peaked around 1.35 briefly during testing. Here's the screenshots for those that may be interested.






Everything is stable with these settings, but I don't think I've seen anyone take the negative offset approach. My 2700k idles fine at these voltages, no lockups or stalls at all. I wanted to maintain a tight load voltage, so went with LLC level 2 and the negative offset was the only way I was able to attain the lower turbo load voltage. It seems to work but any input on consequences of this would be appreciated.

Edit: I may try for a 5Ghz run in the near future, but I want to upgrade my block and TIM before I do. Looking at getting a Koolance 380 and using Indigo Extreme. With that combo I look to gain at least 5 C on my temps, hopefully more but I guess we'll see.

Spidey81 - that's a very good OC. My 2700 (AC waterblock) never gets that hot (max 71oC in p95 or IBT on one hot core, rest under 67oC) BUT my offset is at +0.110 !! And turbo at +0.030 for 48x. It needs about 1.4v to be solid. The jump from 46 to 48 cost me 70 millivolts at load... So i keep it at 47x. 5h stable, no WHEA errors, and no patience for a longer run. Never a freeze or bsod.

No doubt - all chips are different.

With cooling, you may have a >5GHz chip there. The 380 is a very good block, check out the aquacomputer stuff too - not plated.

Hey Guys. I found this thread recently and i can't wait to go over this guide. I am new to overclocking and i have some questions that maybe some of you can answer quickly. I recently built a computer.

These are the specs:
i5 2500k
Asrock Z77 Extreme6
750W power supply
GTX 660 TI superclocked
G.SKILL Ripjaws X Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Enermax ETS-T40 T.B.APOLLISH CPU Cooler(Side Flow) With PWM Twister Bearing Fan Compatible with latest Intel

So now my problem: I used the preset setting for the 4.0 GHZ overclock and whenever i play BF3 i get stuttering and small lag. I read somewhere that you have to increase the Vcore voltage to make the overclock more stable. I am not trying to push the CPU over the limits i just want to give it a little more juice for gaming and CAD and 3D design. if i can get a good overclock at 4.0 i would be happy. Can you guys suggest some good settings to get a stable overclock at 4.0 ghz? Do i need to overclock the RAM? If anyone can help me out i would really appreciate it smile.gif
