Thread: Require help to include quickest quad core on HP xw640

Apparently the PLGA771 edition or descriptions processors decide to function in a LGA771 socket, extra than I have not tested that to facilitate now. The most current stepping is the G0 one, extra than the HP ones were the B3 stepping, LGA771 socket. If you select to get two, do not mix B3 with G0, and I would go by moreover 2 B3's with same sSpec code, or two G0's with similar sSpec code and assume the leap of faith with the purpose of the PLGA771 processors decide to be completely compatible by the LGA771 sockets on the xw6400 motherboard.

The 5100 serial double cores function, commonly, at 60 watts/processor. The exemption is the 5160 functioning with at 80 watts. The 5345 essentially is 2 5160's in same processor shell, mechanically undervolted to keep entire watts to 80. There are a number of reports of functioning not supported, for sure the higher wattage 5400's in the xw6400, extra than I personally may not risk that to facilitate mutually for heat consequences, and longer term CPU board part damage commencing from the higher recent required.

The innovative heatsink/fan for the 60 watt 5100 serial processors with the purpose of arrived by the xw6400 is the sames as for the 80 watt processors. I am functioning with two 5345's with the actual heatsink/fans only presently very well. It very fast, and functioning cool. Thermal probing with CPUID dot com's free HWMonitor demonstrates best temperatures exclusive of raise in fan velocity through the HP PWM fan control system.

Almost bang for the buck if your xw6400 is a solitary double core is to achoived an individual utilized 5345 commencing from eBay and scrap/sell your innovative 5100 series central processing unit and swap in the 5345. With the purpose of way you do not have to buy a second heatsink/fan assembly, which recently go for irregular minimum of 65.00 on eBay, utilized.

I would test to get a used 5345 for considering 110.00, and sell the 5140 after for 15.00. Investigate to ebay beneath the specification code you aspiration, plus xeon. Your entire investment may be approximately 95.00 to get to 7.1. Include in a number of Noctua heat sink compound commencing from Newegg or Amazon thin even layer atop the top contact surface of the processor, ended off by the edge of a credit card.
