CPU upgrade T5600

The  2687W is a validated CPU for the T5600 so it's not a compatibility issue. If you add back the original CPUs does it still work ok? If so, try the new ones one at a time in socket CPU1. If they work ok in CPU1, it looks like it may be a power issue. You could then try disconnecting other components (HDDs, PCI cards etc) to see if then powers up with both new CPUs.

Do you know the size of the PSU you have fitted? (It'll be 635W or 825W)

These CPUs are the V2.  Would that matter? I was wondering if the E5-2687W first versions was the only compatible option.  Is there anyway to figure out the power supply info remotely? I'm not at my home office right now to look at it physically.  When I put the original E5-2620's back in the computer works fine.

I also upgraded to the latest Bios Dell listed for this machine which is A15.  Could it be the V2 isn't compatible, only the version 1?

Hi, are you sure T5600 will works with V2? Is it because of new BIOS update?

I know that dual CPU of E5-2687W, E5-2690 need PSU 835W. However, I am not sure about PSU of dual E5-2660, E5-2670 and E5-2680. Can you confirm whether 635W work with these dual CPUs? Thanks

Do 2 differet heatsinks exist for the High end. on my awaiting replacement of e5-2609 for e5-2687's x 2 - T5600 the front heatsink is lower so it squeezes under the CD Cage

Wow, you bought some nice cpu's! Although they are probably hot runners eh? You are going to have to check up above. I believe one of the earlier comments is about needing better heatsinks.

Also, I wonder if the OP found out that E5 V2 cpu's are or are not compatible with V1's? I thought they were in some instances if the BIOS would support it.

V2 shouldn't be a problem. Do you know if the system had the original hardware configuration when you acquired it? If so, send me a PM with the service tag and I can check the PSU part number and rating for you.

Another thing to consider are the heatsinks There is one for low end CPUs and another for high end ones. I can check them from your service tag too. However, the heatsinks are highly unlikely to cause a no POST situation.

(the heatsink part numbers are 9YYVV - low end, 1TD00 - high end)

I think this information is wrong. I don't think V2's work in same socket as V1 because although they are both 2011, the pin outs are different.

"Different variants (or generations) of the LGA 2011 socket and associated CPUs come with different ILM keying, which makes it possible to install CPUs only into generation-matching sockets. CPUs that are intended to be mounted into LGA 2011-0 (R), LGA 2011-1 (R2) or LGA 2011-v3 (R3) sockets are all mechanically compatible regarding their dimensions and ball pattern pitches, but the designations of contacts are different between generations of the LGA 2011 socket and CPUs, which makes them electrically and logically incompatible. Original LGA 2011 socket is used for Sandy Bridge-E/EP and Ivy Bridge-E/EP processors, while LGA 2011-1 is used for Ivy Bridge-EX (Xeon E7 v2) and Haswell-EX (Xeon E7 V3) CPUs, which were released in February 2014 and May 2015, respectively. LGA 2011-v3 socket is used for Haswell-E and Haswell-EP CPUs, which were released in August and September 2014, respectively

Hello,

Were you able to fix the CPUs issue?

I am having the exactly same issue. I have T5600 and am trying to upgrade the CPUs to E5-2687W V2.

Any help would be highly appreciated.

Hi Guys,

I've checked on this and although the documentation I have states that the T5600 supports Ivy Bridge CPUs, in reality it's not until the next generation of systems (T5610) that Ivy Bridge is supported. Apologies for any confusion.

Thanks.

V2 will not work. they are 602 chipsets and V1 are 600 chipsets

Hello,

Which CPUs require which heat sinks?  You mentioned "9YYVV - low end, 1TD00 - high end" in your post.  I'm considering a CPU upgrade but I'd like to know which heat sinks work with which CPUs.

Thanks in advance,

Rob

This is old but the new A19 bios should work.

A19 bios should work .

O know this is old but did you try the new A19 bios?
