Will an LGA775 Pentium 4 650 (3.40ghz + Hyperthreading) cpu work in a present-day LGA 775 mobo that uses DDR3 or DDR2?
I have a CPU from 2005 that doesn't seem to play well with Windows 7 in its current configuration. i blame this on the motherboard it is in, and also want to use DDR3 with it. The socket type is still in circulation, LGA775, and the motherboards i have seen can support both DDR3 and DDR2. i would prefer to go for one that only accepts DDR3, but the hybrid will allow some flexibility in what RAM i buy. The CPU is a P4 650 with Hyperthreading, @3.40Ghz. will it work in the newer model LGA775 socket motherboards? The mobo it is in still uses AGP and DDR, only 2 slots. The face of the chip reads as follows: INTEL (M)(C)'05
PENTIUM (r)4
650 SL8Q5 CHINA
3.40GHZ/2M/800/
H618A133 (04) or it looks like 04.
so, i take it that means 2M cache, 800mhz FSB, so will this work in any LGA 775 motherboard that supports an 800Mhz FSB?
upgrading for performance reasons, additional RAM storage capability, and newer features/phasing out of legacy connections, such as AGP and Floppy cable (hopefully, what else would you use a floppy cable for?
hmm.. searching newegg, it appears that 800mhz fsb went the way of the 939. is it possible to find a new, compatible mobo for this Prescott? http://www.cpu-world.com/sspec/SL/SL8Q5.html

Yes, it will work with an LGA 775 motherboard that supports 800 MHz FSB and Pentium 4. It is usually mentioned what hardware the motherboard supports on its box. But, I suggest you to upgrade the CPU as well.
If you don't want to spend too much money, try AMD products. They offer better performance for money.

Yeah +1 to that I was able to build an AMD computer for $425 (using black friday deals). 3GHz Quad Core, 4GB DDR3 1333, Radeon HD 5670 512MB, 2 1TB HDDs.
If you go the AMD route, I would suggest it with AM3/DDR3 for better future-proofness.
yeah i usually go AMD. Sadly, i did not do my research last time and got a socket 939. i don't think i need a new motherboard for the LGA 775 anymore, because it turns out that every cpu except mine is a 800mhz 775. so tomorrow, i am adding 2gb ddr2 to a gx280 that has a 3.2ghz cpu, then swapping the 3.2ghz with a 3.4ghz i bought when building the system the question was about, then i will swap the 3.2ghz into a system that i just added 1gb of ddr2 to (and a pretty nice video card that i bought for my 939 but was incompatible) and i will take the 2ghz celeron and put it in the overclocking motherboard that is having issues with windows 7, since it uses DDR anyway. so, the gx280 will have 3/4gb ddr2, although the new 2gb are faster and i should probably remove the existing 1gb to allow the memory to go full speed. it will also get a HD4350 with 512mb ddr3 that i picked up for $35 on newegg. (raised to $40 now) hopefully the gx280 won't have the same issue as the socket 939, which i expect was due to the memory controller built into the cpu only supporting DDR, but i read somewhere that someone had used a HD4350 with DDR2 in the same board, so the problem isn't that it is pcix-16-2.0 card in a 1.0 slot. and the gx280 gets the best CPU, 3.4ghz 1 core 2 threads, 64bit support, etc. the others have 1 core 1 thread. i know this is all 5 year old hardware and i'm due for an upgrade but i'm currently seeking employment so i can't really afford to even put $300ish into a new cpu/mobo/ddr3, which is the plan, keeping my case, drives, and psu.
