New custom water cooled computer. Haven't tried higher. I'm happy with this as a 24/7 OC.

Anyone know the lowest volts for 3.8? I have no idea where to start

less than that mine would do that at about 1V...

Quick question.

I started from scratch (bone stock settings on everything) trying to OC my 3930k. I took a different approach this time, I am using the easytune program in windows to pick out settings and see what the effect is before transferring them to the BIOS for use, as rebooting 155 times an hour got really annoying. I started at my target folding frequency of 4.4ghz and 1.425v to be sure it would run, and I have been working backwards towards the lowest voltage it will run at. I am using IBT standard right now to basically weed out a very unstable OC before I try to run longer/more difficult tests, and I noticed that at a very specific voltage (1.355v) my output time drops by 2 whole seconds and increases by 10Gflops.

I'm wondering if this is the "sweet spot" for this speed on my CPU? 1.350 drops back to 17 seconds and 49gflops, so does 1.360, but 1.355 hit 15 seconds and 59gflops, my temps also drop by 5-6*C per core. Its been a long time since I had a CPU that was so fiddly, and I've never used IBT before so I'm not sure if what I'm seeing agrees with my thought process.

I am considering to be part of the club in the future. Gonna save money after Spring Break is over.thumb.gif

How long is it stable, and with how much memory?

I ran it on very high and it passed (4096MB), but I am going to run P95 for 12 hours once I decide on a voltage that seems like it will work. It finally destabilized at 1.330v and gave me a BSOD, so I'm going to work off of the 1.355 and see what happens. My question was just if the performance increase had any correlation to a voltage that makes the cpu "happy" at that speed.
post #908 of 2291
Yes its true you can find a sweetspot at lower voltage, but what I don't understand is you get 59 G flops when I get 165 G flops with IBT, are you sure you have the latest IBT and the latest windows framework?

I believe so. What version do you have? Also, I'm running my memory at 1333 11-11-11-28 2T right now (stock) because it was giving me all sorts of issues before. I'm going to be ordering some new RAM this weekend, the samsung low voltage seems to not play well with my system.
post #910 of 2291
I have intel burn test 2.53

Sorry I said latest framework but its service pack 1 thatyou need with the latest IBT
Quote:
ou need to have SP1 (service pack) for windows and also the newer version of IBT. This enables the use of AVX (the advanced vector extensions) which double the floating point throughput of Sandy Bridge CPUs.
