Re: Can a bad Core i7 940 processor (or poor placement in socket) cause memory to be lost?

Hello,

If the processor is bad or place it incorrectly on the socket, the system will not boot, but can't cause a memory lost. You could try the following:

1) 1) On the Intel* DX58SO desktop board populate one memory at the time, the blue DIMM close to the processor first and check if the RAM is visible on the BIOS screen then the second and third blue DIMM. If at the end of the test all the RAM is visible we can tell then the memory slots on the board are OK. If you see any problem in one DIMM try a tested good memory stick on it to confirm.

2) 2) If you see any problem, update the BIOS to the latest version 5561. You can get it from the following link: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel%C2%AE+5+Series+Chipset+Boards&ProductProduct=Intel%C2%AE+Desktop+Board+DX58SO

If you have the operating system loaded try the executable version (SOX5810J.86A.5561.EB.EXE) if you don’t try the BIOS recovery (SO5561C.BIO)

Can a bad Core i7 940 processor (or poor placement in socket) cause memory to be lost?

I was running a DX58SO mobo with i7 940 processor and 6 GB DDR-3 RAM. The Souh Bridge chip overheated because a tech knocked the heat sink off of the part. The event may have damaged my RAM and/or my processor.

I moved the processor and RAM to a P6T ASUS mobo (it was available). The system runs but is unstable. The BIOS reports 4087 Bytes of RAM. I removed each of the three 2GB DMIMs 1 at a time (keeping the ones I used in slots A2 and B2 as indicated by the manual. All combinations of DIMMs taken 2 at a time resulted in the BIOS seeing 2039 Bytes of RAM. (I was trying to isolate a bad DIMM)

I set the DRAM timing to 9 9 9 24 as indicated for the memory parts and the volts to 1.5V for the DRAM as indicated at the Mushkin site without any changes except the timings caused an overclock error.

The only thing I have not been able to check is the processor. Can a problem in the processor produce these memory symptoms? Is there something else I should try?
