HP Pro 3120 new CPU is not recognized (beeping).

[eskilla]

Hello.

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/Hp-Pro-3120-Minitower-Pc.html?page=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.

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.

SOLUTION: So apparently this was a memory issue - the new cpu booted with one of my sticks (http://www.electrobyt.com/index.php?main_page=product_info&products_id=6129#.VpD5BFLlnyF) and that one only. No other combinations or singles of my sticks worked. I even tried different dimm-slots for everything.

But now comes the part where I need to find new memory... And I'm so confused on what type I should buy because the one stick that works has the same specs as one that doesn't work.

How come the new CPU only works with: http://www.electrobyt.com/index.php?main_page=product_info&products_id=6129#.VpEPHFLlnyH

And not with: http://www.electrobyt.com/index.php?main_page=product_info&products_id=622#.VpEOclLlnyE

The other CPU were fine with both, and a third one that differs from both the Hynix and Kingston; an A-Data DDR3 4GB 1333MHzDDR3-1333, PC3-10666. It worked (and loaded all 3 sticks á 8gb total) with all combined.

thing is when you deal with a prebuilt like hp anything you do over what it came with out of the box is all your own risk

there only gurenteed to work as is as you bought it ?? [why when you put all the original stuff back its fine ]

also todays newer memory ic may not be supported on that old chipset

example

Hi, I'm Jewel with Kingston Technical Support and would like to offer our assistance. It is possible that the HyperX 4GB memory modules are Single Rank as the latest builds of that part number are Single Rank. Up until recently 4GB modules were standard Dual Rank. Basically, the issue that can occur is that the memory module uses high capacity individual memory chips (DRAM) that the motherboard is not equipped to recognize. Usually, if a motherboard is able to recognized standard 8GB modules it should not have an issue recognizing Single Rank 4GB modules. A "1R" may be printed on the label which would indicate it as single rank. Otherwise, we can confirm this based on a reference number printed on the memory label that we can look up in our system. Other common issue with the DDR2/DDR3 combo motherboards that can be overlooked is that it only supports DDR2 OR DDR3 memory. This means you cannot have both DDR2 AND DDR3 memory installed at the same time, it is an either/or option. We do not currently support your PFG41C-M LX motherboard as we no longer manufacture memory that would be compatible with that motherboard. For any further assistance, please call us at 1-800-435-0640 (USA and Canada only) M - F 6am - 6pm PT and I or another available Technician will assist you. Please be sure to have the part in question on hand when you call

this memory may work on that chipset still ?

best thing to do is contact the memory's vendors support and ask them what memory is still compatible with your chipset
