As the topic states, can a Xeon 7041 CPU be replaced with 7140M?

Mainboard chipset is E7520.

Thanks

Hello cuckoo2010;

It wouldn't be much of an upgrade - more like a sideways move. Both are dual core CPUs - only 400Mhz difference in CPU speed.
Xeon 7041 3.0Ghz 4MB L2 cache / Xeon 3.4Ghz 16MB L2 cache.

You didn't provide the necessary motherboard make and model. You'd need to check the CPU compatibility to be sure. Such as BIOS updates that support the newer 65nm 7140M.

There is a good chance the answer will be no. Xeon 7041 90nm VID Voltage Range =1.2625-1.4125V and Xeon 7140M 65NM VID Voltage Range = 1.10V-1.35V

Hello WR2,

Thank you for your reply.

The goal of the upgrade was to replace the current CPU with one supporting VT-x. The 7140M was the one closest in specs with VT-x support. Same socket, same FSB etc but since it's a different generation I figured it probably wouldn't work.

Thanks again!

It's worth checking the motherboard MFGR's website. It's possible a BIOS update provides the necessary corrections for the CPU VID voltage differences.

Xeon 7041 does support VT-x according to that Intel link above.

Oh my, you are absolutely correct. I had our specs totally mixed up!

Apparently the CPU we have is a Paxville DP (http://ark.intel.com/Product.aspx?id=27202).

I will check with the manufacturer to see if we can replace the cpu's with a pair of 7140M's or 7041's but to me the specs for 7041 looks very much like the DP version.

Thanks for your insight!!
