I have a Dell R510 used for a SQl server. Can I go from E5620 to X5690? They are both in the same Intel Xeon 5600 series. But the i did not know if a X (Performance) is interchangeable E (Mainstream). If not then the fastest upgrade i can make will be to another E.

thx

I can speak to the HP side of this. On the ProLiant DL380 G7 systems, I'd routinely make this type of switch, using the X5690 as a step-up for existing E5620 installations. This is a seamless switch and typically a safe upgrade. The only considerations were cooling requirements for 1U servers, but your R510 is a 2U box. You may also want to ensure that your server's firmware is up-to-date. Use Dell CPU kits/heatsinks.

I have had issues making this type of switch from Nehalem 5500-series CPUs to the newest of the Westmere line (X5690, 5649), even though some Westmeres (X5670) worked fine. Use the normal caution and be prepared to back-out if needed, but you should be fine.

Edit:

The only quick example I have of the CPU change performance impact (with my application) is the difference between Week 36 and Week 38 in the graph below.

ewwhite, what kind of performance gains have you seen going from E5620 to X5690? –  NJinPHX Oct 18 '13 at 3:04
    
@NJinPHX See edit above. –  ewwhite Oct 18 '13 at 13:15
    
@ewwhite is there a reason you chose to upgrade the CPU when the old one wasn't averaging higher than 50% utilization? Do you have some apps that aren't multi-threaded? –  MDMarra Oct 18 '13 at 13:20
    
This was a single-threaded app that relies heavily on clock speed (database lock-read/write-unlock cycles). It can't leverage the multiple cores. So it needs fast CPU and low-latency storage. Going to SSD at the end of Week 38 removed all of the iowait, so right now, the solution is as optimal as it will get. –  ewwhite Oct 18 '13 at 13:32
