The top end 5400 series we validated was the X5472. If you want to buy the top end X5492 and test it in your system then you can, but we haven't validated it. The T5400 supports 5400 series Xeon processors, but we have not validated all of them. The 2950 II top series processor is the Xeon 5300 series quad core. You have one of the top CPUs for a 2950 II. A lot of unvalidated hardware will work fine, but when you put something in that is untested you need to be aware that functionality is trial and error. There are a lot of components that we do not validate for the equipment. If you buy a CPU at a different stepping than what we have validated then it may not work correctly. For best results you will want to buy processors that we have validated for the equipment. Intel and AMD do not make special processors for us. We do not run any kind of proprietary stepping on the CPUs. Yes, it definitely matters when running multiple CPUs as you already know. The X5365 at G0 is supported on the WS490.Īlso, does the "stepping code" matter? I know they must be a "matching pair", but are the processors Dell specific or generic? It should support all validated processors for the WS490. Yes, according to the information you have it is a G1 system board. so it's up to the X5365? I'm not going to go "all out" on this machine either,a balance between speed and cost. P/N: HR381 Assembly Chassis, G1, Precision Workstation, 490, PWA Integrated, ESMT I couldn't find the part # on the motherboard, but looked it up through Dell Product Support. The Precision 490 with the one 5140 shows the following: I checked the three that you mentioned and I show they are all validated(E5440, E5450, X5460) at G0 stepping. There are a few others that are not validated, but they may work. I was just pointing out that there are no 150w that are validated, so those would probably not work. No, I'm not saying that all 80 and 120w of that series will work. From your response it looks like I can use either "E's 80W" or "X's 120W", am I correct? If so, a relatively inexpensive solution would be a pair of E5440 or E5450, or X5460 for slightly more money and the extra watts.
