Hey Guys,

Firstly: if this has been posted/discussed anywhere else in the forums, please spank me soundly and point me in the right direction.

In any case - I've had this 'board for a few weeks now, along with my new PC Power & Cooling 510 Express and an AMD64 3500+ (90nm). I've been VERY busy with work and school, and therefore haven't had much time to mess around with it. Except, of course for immediately overclocking the processor to 250x10 (which was successful) and trying to run my memory at 1:1 with 2.5-3-3-7 timings (which, sadly, was not) .

So I set it to "automatic" and it seems to be running at 208 (?) at 2-2-2-8. I wondered about my memory not achieving the not-entirely-outrageous overclock of 250, it being the new-fanglinest $hit on the block and all...but, whatever, I figured I'd mess with it later. After all, I did get a good 'clock outta my proc, right? Maybe...

So I ran the requisite MemTest and Prime95 for a few hours apiece, and all was good in the kingdom. Until I crashed from the infamous "IRQ_LESS_THAN_OR_EQUAL_TO" blue screen of death a few days later. In fact, many, many more times in the past few weeks. And it wasn't during anything particularly taxing. Maybe a game and Windows Media Player or something. Or basically whenever I was running more than one or two applications at once. Which, to me, sounds like a memory error. Especially considering the particular blue screen I'm getting.

So, I double and triple-checked all my BIOS voltages: Vcore - 1.50 (later 1.55); Memory - 2.80. Kewl, right? Wrong.

I thought that CPU-Z might just need to update (I've got 1.24) because it was reporting only 1.40-1.45 in my Vcore. Even after I went back in and raised it to 1.55! So I then downloaded the latest PC Probe and Motherboard Monitor. They agreed: 1.45 Vcore.

WTF?!

Are they all right? Is this bios not holding/applying my voltage changes? Is there something in the BIOS I haven't set? Have you already discussed this ad nauseum elsewhere in the forum? Have I put you to sleep yet?

Arrrggghhh.

Help an old computer geek out, wouldja?

...hello? Anyone? Anybody? Beuller?

...I got the latest beta BIOS from Asus' German FTP site (1008.003) and it seems to have done the trick - I'm running at 250x10.5 on the proc and the memory at 1:1 @ 2.5 - 3 - 3 - 8.

Now can anyone point me to the thread that shows all the bloody memory timing adjustments for this board? I'm frigging LOST beyond the basic four (CAS TRAS TRCD TRAP).

Thanks in advance!

Beyond the first four, the only other timing that's really of any significance is the Command Rate, which can be 1T or 2T. If you can get that to run stable at 1T, you get a decent boost in memory performance. It might not be stable at higher speeds, though (like all timings.) On my board, the setting was called something like "2T mode" : Auto/Enabled/Disabled. Setting that to Disabled set the cmd rate to 1T.
