GA-EP45-Extreme FSB strap issue?

[osmiumoc]

I have a big problem and I'm not sure if its the board or me being silly.

Took my EP45-Extreme out of storage and preparing for some cold runs but to my horror it somehow does no longer work with FSB above 399? Anyone else ever had a board break like that after a few months of just storing it?

It is not the RAM, I switched 3 kits, tried all slots. It's not the CPU (400FSB should not be an issue on any Wolfdale). I can run 399FSB all day with 32M runs at any memory speed or CPU multiplier. But as soon as I switch from 399 to 400 FSB the board power cycles (probably switching some internal strap) and stops posting. It hangs on C3 (memory issue / bios to DRAM copy). 

I did not change the bios, I did reset the bios, I did reflash the bios. Nothing works. I set all voltages and timings manually, I tried clock skews. Nope, suddenly hard wall at 400FSB.

Is there any component on the board that could provoke such a behavior? Anything I can check visually? There is no corrosion present, board looks clean and I made sure it dried before storing it. 


EDIT: I can even use SetFSB to go over 400FSB and it runs fine, it just wont post if I set it in bios and it switches some internal timing/setting that I have no control over. 

EDIT 2: Switched to a back-up EP45-Extreme and that board runs fine. Guess I'll prep this one and check back on this issue when I'm done.

I've seen this before with my stuff.
After it does this, I can let it sit again and the next time I run it, the board exceeds what it had done before.

Just remember chips and things can just die sitting on a shelf somewhere, I guess this plays in as well as an effect of just sitting around unused.

I figured it out, it was me being a total idiot. Forgot to set the settings for the second RAM channel. There are a bunch of things you can set individual for channel A and B and I only set A and moved on...

At least you figured things out, that's always a win.
