Gigabyte MA790FX DQ6

250htt sounds pretty good to me.
I wonder if Vista is giving me the 233 wall, I have seen a lot of guys get stuck there.

Most of my testing on the MSI was done under Vista64. I only had a few hours under XP before the board died, but it did seem to offer better OC potential. If you don't have too much invested in your Vista install and you have a copy of XP it would probably be worth the switch.

I played with the HT Ref clock quite a bit last night, and I can still get close to 250 using AOD, but trying to get it to boot from BIOS above 235 was pretty much impossible, it may be a limit of my board...

I even cranked up the HTT/HTR/SB voltages and it still seemed to hit a wall..
I know the chip will do 250, cause 250x10x8x8 was my everyday stable on the K9A2... Just thought I'd let ya know my experiences..

From what I can just remember, it used to be that computers overclocked better under Win98 than under XP. I think that each succeeding release adds an extra level of complexity that means a previous-stable overclock cannot be maintained.

Hey Aussie, seems like you've had the Gigabyte board longer than I have, have you played with the "AutoExpress" features in Bios?

This is a very preliminary result, but it seems like setting the CPU Optimization function to enabled does help stability..

I'm still stuck at around 230ht, but it just seems to run a little smoother/more stable.



I do worry a little about the way this board handles CPU v's. My CPU is actually set at 1.325 in bios, and without load it will run close to that, but as you can see it's pushing 1.4 under full load (running Prime 4 core).... I may be a wuss, but I'm not sure I'm comfortable with that.

It may very well be a bios thing, but the K9A2 didn't seem to get squirley on the HT Ref clock until 250.
