LE: yep, 1.262V bios / 1.232 CPU-z and still stable at 7.5x500. This is really disorientating.

I've got my 515X8 somewhere. I will try and find them, but fill in the chart Grish the Dish posted.

Gah, I tried to stabilze my cpu at 3.6Ghz, and it won't do it no matter what. I tried 1.32V MCH, 1.58xxV Vcore, and CPU Term a few notches below Vcore, and ram running at 800Mhz with 400x9. Still crashes after priming. Any other ideas?

Hi

I don't know if i did it a bad way, but all i did was. Set my V-Core and Ram voltages and left the rest on Auto. And then played with the FSB

And tested with Intel Burn test and got stable, just playing with the V-Core.

Then i set the CPU voltage Term manually, and tested with IBT and got it stable.
Then the next and so on.

Just my

Some might say I'm a crazy fool

But i have not had any problems so far, and I'm only @ 4GHz cos that is all i wanted

I also have had it almost IBT stable @ 533MHz FSB Ram 1:1

^^^^^

AC,I am finding that there is no bad way and no hard fast rule for the settings. I have run into problems at higher FSB (500) and had to set my CPU Term higher than my v-core in order to get only 1 hour of prime. As much as I hate to say it, it looks like my theories of V-core and Term relationship don't hold up at higher levels. Sometimes you just have to punt the ball and hope it's the right thing to do

edit: I am going to give your method a go on my next attempt as I am not improving all that much with my strategy.

ACHILEE5 · 06-21-09

All i needed from this Board was 422 FSB and it gives me that so I'm a happy bunny

Oh, one thing!
The warranty on this board, how long is it?
And do i need to register with Gigabyte?
And do i deal with Gigabyte or the Shop i bought it?
This ones worth a Rep+

supa, good deal man... I just realized that you have OCZ 1200 RAM, so, uh, what's the big deal... haha, you should-a been running at 1200 from the git-go

Ha yeah I know. Well, for several days it seemed impossible to get it to even boot out of 1:1. Finally got passed that but then couldn't get it to stay stable. Even now a couple days later those settings have proved to not be 'truly' 24/7 stable. On some renderings I put it on it would bsod after 6-7 hours. At this point it seems that what it needed is more mch core. I know it seems like I'm already running a lot, but i've tried every nook & cranny on this board and 'moar mch' is the only thing producing any results. Have it at 1.46v now and I'm currently running a rendering on it to make sure it can last at least 24 hours. So far it's lasted far longer than anything else i've tried, so I hope this is it.

I am currently using a software RAMdisk (as of last night) with 1.5GB of RAM dedicated to it for my pagefile; haven't noticed any dramatic differences yet, though. But if I go hardware RAMdisk, then I will use it for something a little more substantial, maybe to house my browser...? Haven't decided yet.

I'm not at all familiar w/ that. What is it?

I got mine in the mail today... if my case dries quick I'll probably be reporting back for help tonight. ^^

Very cool your going to love it. Post your results as you go.
