Upgrading processor on Precision T7500
Hello. I recently purchased a used Precision T7500 machine with dual L5518 processors. I didn't think the T7500 supported the lower power Xeon processors but it boots just fine. I then purchased two X5660 processors for a bit more speed. I removed the riser card and replaced just the single L5518 on the motherboard with a single X5660. The machine powers up but displays no bios whatsoever. The main power button on the front is steady green but the only number displayed is a "2" which is identified by the error "reserved" in the manual. The motherboard date is 2008. Is it too old to recognize the newer X5660 processor? Putting the L5518 back in allows it to boot successfully. I put a bunch of money into the two new processors and would appreciate any support I can get. The only card installed is a PCIe2 graphics card which works fine. Thanks.

Hi BIPD,
No need to be sorry! It's great that you came back and told everyone what resolved your problem - other customers may be in the same situation as yourself so your contribution is very valuable indeed. Thank you for that!
Tetrapackage - have you tried updating the BIOS for your system to see if this resolves the issue?
Hi,
I think I have exactly the same problem ... I have 6x motherboards - 2x looks to be permanently dead, 1x sometimes boots, sometimes not - bought it in this state, and 3x are booting perfectly fine with X5550 but won't boot with E5603.
I know I probably should update BIOS ... but I don't want to kill them ... and I'm not talking about power loss - will the latest BIOS version still support X5550 ?
thanks

I also have a motherboard that has been bought way back 2008. I also have the same problem and was thinking that it could be possible that the new processor is not compatible with the old board. Whenever I use the default one, everything works normal.
