I want to replace my Sempron LE processor with an Athalon II Duo-core both 64 bit, both AM2+ and both 95 watt CPU's
Other than pulling the Sempron out and plugging the Athalon in, is there anything I need to do? Like edit anything in the Bios? or will it all just configure itself?
Desktop is a HP Slimline with a PEGATRON NARRA-5 MB, CPU is a 2200 Mhz 1.2 V
External clock is 200Mhz.
Answers to another thread indicated my Mobo would not support the 125 Watt CPUs. Most of the ones listed are for socket AM3 on Neweggs and TigerDirect sites. I haven't found any spec's for the NARRA-5 Mobo so I am not sure of the CPU wattage supported.
I'd much rather go Quad if the low wattage PS and mobo can support it.
TigreDirect has 2 good options: the AM2+ Phenom 2 X4 920 for $90 and the Athlon X2 7850 for $50. Both are AM2+ and both are 95W. They are OEM: no heatsink, limited warranty, but you all ready have one and I've never had a CPU die. Just make sure you buy some thermal paste to go with it.
I would not risk getting an AM3 955, if you look around you may find 95W AM2+ 940s.
The CPU should just detect. You might have to reinstall the OS, but the Windows license that came with the computer is tied to the motherboard.
I wondered about the AM2+ Phenom 2 X4 920. It is listed at 125 watts and I keep reading that I need to stay with the original wattage, in this case that's 95 watts. Some warn of damaging the mobo by installing a higher wattage (load) CPU than the mobo was designed for.
Some have stated that the Socket AM3 CPU's will work in AM2/AM2+ socket mobo's
IS THAT TRUE? CAN I PUT A AM3 CPU [Phenom II X4 945 Quad Core Processor - 3.00GHz, Socket AM3] IN MY MOBO (Phoenix -v, 5.49) OR NOT?
IF I AM STUCK WITH A 95 WATT CPU AND AM2 SOCKET, MY CHOICES ARE VERY LIMITED.
You're right the 920 is 125 W. The AM3 backwards compatibility is dictated by the motherboard. Generally, yes a AM3 will work in a AM2+ motherboard. HP is lazy or decides to build in planned obsolescence into their products and doesn't update the motherboards for newer CPUs.
