nothing i'm building a pc and just recently bought a bundle of parts from tigerdirect.ca. i saw that the socket AM3 phenom II x3 is backwards compatible with AM2+ mobos, but i wanna know if there will be a significant difference in performance,(or if it will work at all)
got ya, yes the vast majority of AM2+ boards are backwards compatible with AM3 cpu's usually needing a bios update. what you lose in using a a AM2+ board is support for DDR3. however DDR3 is twice the cost and performance increase is minimal at this time. if your going to have the machine for a couple years it may be worth the 'future proof' investment. (notice the quotes around that phrase) LOL.
I guess i should have said 'forward compatible" to be more accurate.
depends on when it was manufactured, you may need to update it yourself as the phenom II are rather new cpu's.to answer your question about the performance difference between DDR2 and DDR3 the answer is negligible. nothing that you would notice in real world applications 1% territory. here is a review with benchmarks comparing the performance of the two http://www.tweaktown.com/articles/1782/amd_phenom_ii_ddr2_vs_ddr3_performance/index.html
wow thanks - thats just what i was looking for. The DDR3 performance will only go up in time though, and since my CPU supports AM3 as well, i guess it worked out pretty well that i got an AM2+ motherboard for now withh DDR2 since there isn't a huge difference in performance yet, but if i ever wanted to upgrade my mobo, i could.
Thanks again that benchmark was just what i googled for!
the spec page @ biostar says it supports all of the Phenom II x4's with latest bios. they don't always update the cpu support list in a timely manner, and the x4 965 did just come out. the reason i said that is because its not a good idea to just flash the bios"just in case' , there is a certain amount of risk if it doesn't go well, or the power is interrupted or such. you can end up with a very expensive bookend.
I have found that others have gotten the 9950BE to work, but there is a 15w difference from the 9950BE to the 965BE.
Others have complained that with new bios updates that they get a error during post for any processors over 95w and that there is no fix or ability to roll back to previous bios.
Would it be safe to run with same bios? (stock bios)
Also on the "CPU support" section for that board all the processors it says it supports except one, the "AMD Athlon™ 64 X2 Dual-Core 6000+" at 125w, are 95w or under. Makes me wonder.. Maybe that's why people have been getting that post error message and power off?
when I entered the board on biostars own site, it comes back no data....nice support, but from what i can find it doesn't support 125w CPU's. like i said, i just am not a big fan of flashing the bios,just to try something out, cause if something goes wrong , you can trash the whole thing
