mother board compatibility

Hi i was wondering if a ASUS M5A97 would be compatable with a CORSAIR Vengeance 12GB

these are good modules .. they are 1.5v
they will work, compatibility: http://www.asus.com/Motherboards/M5A97_R20/#support

however i would recommend going for "a kit of two modules" for amd
3 module kits might be more optimized for intel timings since they had 3 channel mem on 1366 socket...
also in this case you would have dual channel interleaved mode... 8 gigs would go in dual channel and the other 4 in single or something like that...

however since they are 1600mhz cl9 there will be no problems ... am3+ cpu's have stock up to 1866mhz support with 2 slots / 1600mhz with 4

just activate x.m.p profile in bios

Thanks man

There's no "XMP" on AMD platforms.

tell that to my gigabyte GA-970A-UD3P motherboard... i'm running xmp profile1 right now...
xmp profiles are saved into the memory modules,
however the timings themselves might be more optimized for intel memory controllers...

 

[raja@asus]

That'r right. The profile is designed for Intel chipsets as it's their tech. The AMD IMCs may not be stable when used with such profiles...

pretty sure that apart from all the marketing nonsense it's just a way to save memory timings, select them manually yourself and there will be no difference, just a convenience feature... if my memory modules would be faster than advisable for my cpu then i would go in there and try to readjust them and do a bunch of stress testing etc. but since i have a kingston hyperx genesis 1600mhz cl9 kit of 2 i can't see any problems for my fx-6350

It's a plug-and-play feature designed for ease of use and IT IS specific to platform. Seeing as most users don't understand what timings mean - many are lost when it comes to setting them manually. Add in the mix of them being set by density and binned for specific modules, and you get into a grey areas - especially at higher frequencies. Case in point, try running DDR3-2133+ Intel binned kits on older AMD CPUs and see how close one gets to stability. If you don't know what to adjust, you're screwed. There is a reason, that reputable memory vendors stipulate which platforms a kit was binned on. It's not just marketing - it's because IMC architectures play a part in the achievable memory frequency and sub-timing set. On top of that XMP won't adjust CPU/NB voltage unless the mobo for the end user - it's not part of the XMP profile (MB vendor has to tie in their own routines that scale with DRAM ratio). At higher DRAM frequencies the older AMD are very sensitive to having the correct CPU-NB voltage applied. Features such as XMP and D.O.C.P features are designed for users that DON'T want to set things manually, not for those that do.



When you deal with LOTs of support cases like I do, you kinda get the lay of the land, rather than personal experience and observation of a few forum posts.

well yes - i didn't mean to come off as ignorant, honestly i wasn't far from buying a 2400mhz hyperx beast kit of 2 myself... last minute "budget cut" and christmas planning came up, now i see what trouble it would have brought upon me...
