Which slots are used for memory risers?
Did you tried to use memory without risers?
Try to install 8 DIMM to slots 1-8.

i just removed the memory riser & populated the 8 slots from 1 to 8 with 4GB modules. same result! tried with one processor, works like a charm!
I tried populating one DIMM, & then 2 DiMM's, same result. tried with one processor, works like a charm!
any other ideas before I reassemble?

Sorry, no more ideas.

I just installed 2 X5355 cpu's on my My171 A00 motherboard with A08 bios with no problems. Booted right up. I was worried with the info I found online but I tried it anyway. I unplugged the power cord and removed battery during the switch. Plugged battery and cord back in when new cpu's were in place. Fired it up and it booted to windows. Had to reboot once more before Windows recognized the quad core. I hope this helps!

These quad's are not slow by no means and are quite powerful if you used two of them... I have ran the L5320 1.86Ghz 50W, L5335 2Ghz 50W... They are not any slower that I can tell from a newer E5405 1333 12MB cache xeon...

Only 50 Watts.. so like 30-45C load across all cores and it it's in the low 40s full tilt, I have seen it auto-overclock to almost 2.1Ghz on the L5320 from 1.86Ghz... Couple megahertz to the fsb when running really cool.

http://www.cpu-world.com/sspec/SL/SLA4Q.html - 06F7h - 1.86Ghz - plenty fast for 1080p gaming on a solid gpu on just 1 cpu.
http://www.cpu-world.com/sspec/SL/SLAEN.html - 06FBh - 2.00Ghz - plenty fast for really anything you would realistically use it for.. especially 2x

I have two X5460 CPUs, so it's impossible to use these two CPUs in the latest revision of this board?

... Xeon 5400-series aren't supported by hardware.

Any word on anyone successfully running old school 1066 Quad Core's on this system? Thanks
