HP Pro 3120 MT CPU upgrade gets beeping.

Don't ask how to over-clock.

I upgraded my cpu but when I boot up the computer it gives me 1 short + 1 long beep repeating on a black screen. At first I thought this was an hardware issue - but after some research and asking around on forums it seems to be an BIOS-issue.

Apparently my mobo and chipset can handle the new cpu, but the BIOS are so poorly constructed that it won't allow it.

I was hoping some BIOS-genious knew a workaround... Here are all the necessary info (I hope):

My computer: http://www.manualslib.com/manual/435619 ... e=2#manual & http://www8.hp.com/h20195/v2/GetPDF.aspx/c04288430.pdf

CPU upgrade: from *E5500, 2-MB cache, 2.80 GHz* to *Q8400, 4-MB cache, 2.66 GHz*

Beep code: Memory issue.

Memory: 8gb (1x 4gb + 2x 2gb) PC3-10600 DDR3

wmic baseboard get: Manufacturer: Pegatron Corporation / Product: 2A94 / Version: 1.03

BIOS version: American Megatrends Inc. 6.09, 2012-01-16

SMBIOS version: 2.5

OS: Windows 7, 64-bit.

Tried: Running it with no memory sticks, running it with 1 stick (and switching sticks), reinstall BIOS, downgrade BIOS (since the version I already had was the latest), upgrade BIOS from the downgrade.

Additional: New thermal paste between changes and all that. The fan doesn't seem to run any faster than usual when I try to boot with the new processor. And when I boot up with the old cpu back everything runs fine.

Hopefully someone can help, thanks in advance.

Supports only 2GB modules so you need to change that 4GB with 2x 2GB. It seems that for the x8*** processors you need v6.09 of the bios

Do not assume anything

System error, strike any user to continue...
