Supermicro X8DTE-F Bios flash issue

[h0mez]

I had a X8DTE-F with the v1.0 BIOs on it, it wasn't working with my X5650(s). So I picked up a L5520, and it booted up fine. Downloaded the latest BIOS, flashed it, it flashed fine. Go to restart the mobo, won't post now.

Is it possible I did something? Is it possibly my L5520 isn't somehow compatible with the new BIOS, nor the x5650? I tried going through the BIOS recovery process on Supermicros site, and various instructions for the AMI BIOS itself, but it never lights up my USB key led.

Nevermind, must have fried my CPU(s) somehow. They won't work in other systems, not quite sure how I did it. Might have been the stupid all in one water cooler, hooks must have slipped and I didnt have it the heatsink pressured down.

But It doesn't quite explain how I go from updating the BIOS successfully, then hitting ctrl+alt+del, then no post. Theres no way a BIOs update could do something to my CPUs to cause them to not work in another system is there? I'm really grasping at straws here.

not to necro an old thread but i have the same board with two L5520s and during a swap to a Lian Li PC-8000 it went from working to not. The fans spin up for half a second and then nothing. No beeping either. Did you have something similar happen when you decided the cpus were fried?
