Hello,I have a socket AM2 mobo I know the AM3's are not backwards compatible with am2 and am2+ due to the memory controller but are they making new flavors for the backwards compatibility? I have a Asus M2NPV-VM mobo, ddr 2 800 memory and are considering upgrades
According to this http://en.wikipedia.org/wiki/AM2%2B the am3 cpu needs the presence of the ddr3 memory to work. Also am3 cpu's have 941 pins. So its up to the mobo being compatible. I am considering getting a quad core vs a phenom need my pc more of a workhorse then a gaming machine. I would want to get a better cpu so it would be an easy fit when I get a new mobo down the road. Also when considering this cpu ddr3 has 240 pins could I just underclock the ram because I will be upgrading that 2.
Thanks for that great link!!!! Thats hit the nail right on head!!! My next question would be the ram, my current mobo does ddr 2 800 mhz up to 8 gig thinking ahead when I buy a new mobo down the road I wanna just swap in the newer parts can I right now buy ddr3 memory and will that work with my current mobo?
"AM3 processors work on AM2+ motherboards due to the presence of both the DDR2 and DDR3 memory controller"
"AM2+ processors do not work on AM3 motherboards due to the processor's lack of a DDR3 memory controller"
I wasn't questioning the backwards compatibility of the AM3 CPU if you notice It does say you "need" the presence of the ddr3 controller for the AM3 cpu to work and as long as your am2+ does then your all set but I have a older am2 mobo with just a ddr2 controller so thats why I am concerned.
You keep your DDR2 and Asus M2NPV-VM, flash the BIOS to 5005 and you can add the Athlon II X4 635 now.
You can move the Athlon II X4 635 over into a new AM3 motherboard with DDR3 when you get ready to continue your upgrading program.
because of this awesome knowledge I have to reconsider my upgrade options my 1 gig of Ram is holding my system back and need to decide whether to keep this mobo instead of getting a newer cpu. I could get a newer board, newer chip, newer ram and try to get what I can for my old stuff and use the money for the more newer upgradeable faster stuff
Damn you are the best!!! Thank You for the awesome info!!! Wish I could help you in some way. Been coming to this site for close to 10 years and it never fails!!! Thanks Guys and Toms hardware!
