My problem is this, my phenom is an old cpu and I love it, so I'm reluctant to swap it out, although the fx 81 looks tasty. When I build the system and did a dry test boot (no drives or cards just the psu and M/B with ram 1 stick of ram and cpu with cpu cooling block, the CPU led on the M/B lit and stayed lit, I tried powering down, and clearing the bios by hoping the jumpers, 1- to 2-3 then power up and and down reset to 1-2. I tried, reseating the cpu and re-apply AS5, i tried switching the ram, I exhausted everything I know and thinking of an RMA to dabs, I know it's not my cpu or ram as they work on another build. I've triedout of case booting, in case booting, dry and wet cooling, changed psu from my ocz 750 to a corsair 550w gold.
Is there any tricks to the sabretooth? besides throwing out the window!! This realy sucks, I got this little voice in my hed saying it's a DOA, but a louder voice saying ASUS would never do that to me lol.. Any suggestions would be great
The CPU LED stays on... why is that an issue? I have the same board with a x3 720 o/c to 3.4. I really think that you need to hook up at least your video and boot to BIOS. Your description is not completely, well, descriptive.
The CPU led is not supposed to stay red, I have hooked up my cards, 1 of them at least, it doesn't boot, it won't post or anything, the fans start, when I attach my mechanicals they spin, but the CPU led on my stays lit red and that's it. It goes no further.
Ok, you didn't specify that the LED was red. Can you get another PII CPU to try? Maybe take the board to a local shop and ask them to try another CPU? After that, it is likely DOA. An FX chip should run on the 0901 BIOS without an update. I picked up a Phenom II 980 a couple weeks ago on Newegg ($150) as insurance and really wouldn't bother with FX chips right now. Lots of posts about that discussion here.
