Hello bobuser,   I see you are checking on CPU upgrade to 5600 series.  I was able to find two that we have validated for the T610. If neither of these are the one you are looking for you could contact sales to see if they have it.   Part# 0N8JG  -  1.86/4.8Ghz, 12M Cache Westmere-EP Processor, L5609 Part# F2YJ6  -  2.13/5.86Ghz, 12M Cache Westmere-EP Processor, L5630   I would also mention to make sure you system firmware is up to date: [URL]   Please let me know if this helps you.
Hi, I've been an extremely happy customer of Dell forever. I have a workhorse T610 and it's just the best. I even have a 2nd T610 just in case the main one falls over (which it never has) to get going right away. But, it is now feeling it's age - and I should upgrade to the latest. But, I really just use the box as a host for VMWare workstation. I've tried ESX, but I just like Workstation running under Windows for lots of reasons. But, the problem is that the latest VMWare Workstation won't support the T610 CPU that I have (only by one version). I have the Xeon E5506 @ 2,13Ghz (2 of them) and from the VMWare site only the 5600 is supported for the latest VMWare Workstation. [URL] Yes, I still run VMWare Workstation V12 - which is fine enough for now, but I would like to upgrade to latest version. One idea was to just upgrade the CPU to the next tiny version of the CPU. One the site it says: ---------- Systems using Intel processors based on the 2010 “Westmere” micro-architecture (e.g. Xeon 5600 ---------- So, do you think this is a valid idea?  Yes, I know I should upgrade to the latest server - but if I just wanted to keep everything as is, could this idea work? If so, can you point to a CPU that would work? (Amazon or ebay or Intel site) I know I can't just jump to any CPU due to DIMM requirements.   Thanks for all suggestions.
