Getting i7 920 above 4.3Ghz

post #1 of 2
Thread Starter 
Hello all!

Here's my current setup:
205x21
i7 920 (can't remember the stepping--it's a week 38, I believe? 4Ghz @ ~1.2V)
MSI X58A-GD65 (have had it at 220BCLK, so that shouldn't be an issue)
G.Skill DDR3 1600 6GB 7-8-7-24-2T 1.5V

Currently, I'm stable at 4.3Ghz:
1.3V VTT, 1.65V Vmem, 108Mhz PCI-E, 1.35V Vcore, 1.89V PLL

The problem is, getting to 4.3 was quite difficult--for some reason, every time I get a minute or two into IBT, the computer starts making noises, which get more frequent until the computer crashes (usually just a hard reboot without a BSOD). I've tried increasing and decreasing voltages, you name it--without any success. Temperatures are reasonable--usually in the 70C range.

Am I satisfied at 4.3Ghz? I guess. However, since it is a great chip, I guess I was expecting a bit more out of it--I would like 4.4 or 4.5, or until it requires more Vcore than I want to put into it for 24/7 usage. Any ideas?

Sounds like you are close to the wall.

My chip behaves similarly. Needs only 1.28v for 4.2, 1.31 for 4.3, but needs almost 1.4 and 1.375VTT for 4.4.

After running my chip at 4.4 for a month and seeing my power bill, I decided to stay with 4.2 for 24/7. 4.0 would probably be even smarter.
