Make sure you only buy Xeons with a TDP supported by your motherboard
TDP is a measure of how much heat your processor’s cooling system will have to handle.
Some motherboards will not boot with processors over 95W (or 65W for low power boards).
TDPs for some common Xeon processors
- L54xx series has a max TDP of 50W
- E54xx series has a max TDP of 80W
- X54xx series with a 1333 FSB has a max TDP of 120W
- X54xx series with a 1600 FSB has a max TDP of 150W
A good way to check if your motherboard supports 120W and above processors is to check the CPU support list. If your system supports the 130W QX9650, you should be able to run the 120W X54xx series Xeons (and also probably the 150W Xeons with a 1600 FSB). However, if your system only supports the 95W Q6600 with a G0 stepping (and not the 105W B3 stepping), your system likely only supports 95W and below processors.
If you aren’t sure what TDP your motherboard supports, I’d recommend going with the 95W and lower Xeons only.
Mod warty świeczki przy dobrym wykręceniu xeona, a to już zależy od zasilacza, płyty, chłodzenia i rewizji proca. Generalnie streszczając to seria "e" ma TPD 80W co daje potencjał na duże oc ( "L" ponoć nie idą tak wysoko), a xeon e5450 ma 3GHz na starcie.
