Gigabyte EX58-UD5/Extreme Discussion Thread

[Carfax]

I raised the BCLK to 213...so far so good. Looks like this will be my new setting for everyday use.

Hey dude, you and I have almost the same set up. Could you help me out a bit?

I just put this rig together today, and it's the first time I've ever built a computer based on the Core i7 platform so I'm a bit of a n00b on this one...

I have a d0 chip, and I thought I could hit 4.2ghz easily, but I was wrong, or maybe my settings are screwed up, or the Prolimatech can't handle 4.2ghz.

When I run Prime, my temp sky rockets to 74c, which promptly crashes my computer..

I couldn't believe the temps would be that high, because from the reviews I've read, the Prolimatech Megahalems is supposed to be in the top three best heatsinks.

Anyway, I checked to see if it was mounted right, and it was.

Help would be much appreciated!

Hmm, 74c shouldn't crash the system, in fact it is reasonable temperature when using this high overclocking and air cooling, with my old EX58-Extreme and c0 920 CPU I could reach 85c @ 3.8GHz when using prime95 and coolermaster V8, the system was rock stable.

Do you think it could be because I have some kind of failure protection enabled or something?

OK I found the problem! It was the "Performance Enhance" option. I had it on extreme, and after I changed it to turbo, I can now run at 4ghz with stability

One strange thing though, is that unless my Vcore and VTT are in automatic mode, I can't even boot up. I've tried almost every setting, and I could never boot up until I put both in automatic.

Could you post you the voltages you set in the BIOS? Thanks

Yeah, I used 1.4v on the Vcore and 1.37 VTT. I also played with the IOH setting, though I have no clue what it does. I used 1.26v for that one..

At the time, I was just trying to get it to boot, but every time it would reboot during the boot up process, or BSOD.

Putting my voltages to auto fixed everything though.. Still, I'd like to get my voltages as low as possible.

BTW, I've got turbo enabled now. Running at 4.2ghz with no crashes or lock ups. It was that damn performance enhancement that messed me up!

[Carfax]

Bleh, I think I'm sending this board back and exchanging it for a Classified.

4ghz is rock steady, but with turbo on, I run into issues..

And I still can't figure out why manually setting the voltages causes my computer to crash or reset upon boot up.

Maybe I should flash to F9 bios, but I've heard bad things about it.
