kid41212003AMD stated in their documents, that AM3 cpu will run on AM2+ mainboards.
People expect all the AM2+ mobo will support it. It's AMD's fault in my point of view.
Oh well, I'm not really expect my mobo would run AMD3 cpu (AM2 socket), because I'm going Intel soon anyway.

well we've already had that. AM2 boards that wont take AM2+(phenoms), AM2+ that cant take 140W AM2 (Athlon) CPU's.... AMD's CPU support is a total mess.

Intel's was worse when the 45's came out. Most P35 and under didn't support anything without a bios flash..

Remember this was the Same Situation Intel was in with the P4 and even the Early Core 2 Mobos cant support the quads.

eidairaman1Remember this was the Same Situation Intel was in with the P4 and even the Early Core 2 Mobos cant support the quads.

except that intel never said it *would* work, while AMD did.

Most Phenoms do work on AM2 boards. I know the 500 series chipsets had support along with some Nforce 500's.

well lets just hope amd does it right, heck we already know they are make Am2+ deneb anyways so I see honest reason to complain, now maybe everyone can't afford those but still I think its a bit better than nothing.

ShadowFoldMost Phenoms do work on AM2 boards. I know the 500 series chipsets had support along with some Nforce 500's.

i know of two people with boards that cant. ones my new housemate, the others my dad. ones an asus board, ones a gigabyte. Unsure chipsets used, i'm pretty sure they're Nvidia but no idea what ones.

AMD shouldnt make blanket claims, it all comes down to the chipsets used in the boards, and manufacturers do stupid things there (re-using Nforce 4 seems popular)

i think new AM3 mobos come with new product name , how we can recognize 790fx with AM2 and new one with AM3

hayder.masteri think new AM3 mobos come with new product name , how we can recognize 790fx with AM2 and new one with AM3

the chipset can be the same, the motherboards from the manufacturers will be named differently.

My old board, ASUS CROSSHAIR (nForce 590) was running just fine with
the 9850 BE- after ASUS made a BIOS update.. so it is maybe possible to get AM2 boards AM3 compatible?? or atleast AM2+ boards.
For what I can recall from ASUS's BIOS update, it was something about the memory speeds (800 - 1066 MHz)

Musselsall you people complaining about lack of AM3 support on your boards: you do realise that has nothing to do with asus, and all about the boards you chose? if you want an AM3 supporting board, WAIT til its known. its your own fault for buying unsupported boards.

The AMD promise: Every AM3 processor would be backwards-compatible with AM2+ and AM2 motherboards, AM2+ processors with AM3 and AM2, AM2 with AM2+ and AM3 (provided the supportive memory standard is there on the motherboard). So from AMD's side it's possibile, not from motherboard vendors' side, and not because it's impossible. They want you to buy a new motherboard each time you upgrade your AMD processor, which originally shouldn't be the case. Isn't that a put-off? Wouldn't you want to switch over to Intel since you're made to buy both the processor and motherboard anyway?

the AMD promise thats not holding true. is that the motherboard manufacturers fault, the chipset manufacturers fault, or AMD's fault?

Motherboard vendors'. AMD isn't doing anything on its side that causes incompatibility? What makes a M3A32-MVP incapable of AM3, when a M3A79-T is? (they're both AM2+ boards based on the same AMD 790FX). Chipset has nothing to do with CPU compatibility. All its job is, is to provide a HyperTransport connection to the rest of the system. Technically even a nForce 3 (that ran those s754 chips) is capable to run a Phenom II X4, although the socket doesn't permit that.

Isn't all those unsupported AM3 CPU mobo are AM2+?
AMD stated a simple thing, that AM3 CPU would run on AM2+ sockets. Aren't those unsupported AM3 CPU mobo are AM2+?
If they stated AM3 CPU would run on AMD Chipsit AM2+ mobo, then It would be different story.

Its all about BIOS coding, and also if they want to milk you of money or not, its not AMD that controls the Motherboard Manufacturers Compatibility with Certain CPUs but the Manufacturers Themselves, beyond that who has a 790FX with 600SB.

Neither BIOS, nor SB600 shouldn't have anything to do with AM3 compatibility. MSI enabled its 790FX + SB600 board to support AM3 chips. It's all about them sandbagging to milk you, which is a scam. It's not something restricted to ASUS, all vendors are guilty of this. A lot of people faced disappointent when their MSI AM2 nForce 570 SLI / 590 SLI boards didn't support Phenom.

Oh, and I just forgot: Crosshair II Formula doesn't support AM3 either. Shame.

yeah this is all about greed, bios are the only reasion, chipset has NO EFFECT on this, there are am2 boards with sis chipsets that came out long b4 the am2 socket came out(well use to be, havent seen any for a while but i have seen them and used them)

this isnt like am2 vs am2+, alot of am2 boards lacked enought room in their EEPROM's(bios chips) to accept the needed code to support k10, Really any am2 board could take a k10 IF u replaced the bios chip with one that was large enought containing the am2+ bios the board would support those chips.

Also talking about the 125 and 140watt cpu's and some am2+ boards, this was due to volt chips used, alot of boards blew out on 9850's at stock clocks due to power draw excceding what the boards chips could maintain, I have seen 790fx msi, asus, gigabyte and other brands burn out.

weird one was the biostar ta770's a cheap board thats managed to support the 9850be without blowing dispite being a cheapo board(but a great one for clockers)

board makers should have thought ahead and used better fets but they didnt, so well, rev2 boards had to come out to support 125 and 140watt chips.

cant wait to see the new chips, From what I understand biostar plans to offer bios updates to support new 45nm core chips, so they are a good bet if you want a kickass overclocking board, the ta790gx3 is a pretty sweet board :D

I have a 140W board, I bought it to support the current offering, plus one more upgrade later to the CPU plus crossfire. Now I am being told that they will NOT support it, and yet Deneb has been seen running in the same chipsets on different boards?



Sounds like a lawsuit brewing against AMD and some board makers for false advertising to me.

its not amd's fault here Steevo, board makers are the ones who have to supply the needed bios upgrade PERIOD, if they choose not to, then your welcome to try and sue them, but unless u can start somthing like a classaction your pretty much screwed.

best bet is to get enought outrage in the geek community to force/shame them into putting out the damn update, asus sucks for MOTHERBOARDS, at least for AMD boards, for intel i hear they are fine.

My advice just email Asus and tell them you wont be buying another ASUS product due to them not updating perfectly capable boards to support new cpu's.

if anybody wants to email somebody at asus to complain about this
MEGAN_NESMITH@asus.com

shes a NICE rma rep, and im sure would forword your emails to the proper person OR will give you the proper addy to address complains to :)

I think the reason why the M3A32-MVP is not supported is because of the South Bridge, it's not 700 or 750 to support AM3 like the rest. The M3A32 has SB600 so it can't be done with a BIOS update.

The only thing I would complain about is why they would release a Phenom Board with SB600; seems to me they just wanted to rush a release with something to get it flowing.

AphexDreamer, the chipset has ZERO to do with it, the 700 is just a 600 with some minor changes, mainly 2 more sata ports.

i think you need to try and understand the tech b4 you assume that the chipset matters.

truth is that an nf4 board COULD run an am2+ or even am3 chip just as the old first gen ATI crossire set with sb400/450 could run am2+(but who would do that, the usb perf on that set suckd!!)

its simply a bios update that is needed, nothing more.......

FudFighterits simply a bios update that is needed, nothing more.......

thats not true in all situations. as stated before, some boards couldnt handle higher power draw, some had physical limitations due to the BIOS chip. SOME boards only need a BIOS update, but how can you be sure that a hardware update isnt neccesary too?

one good example here from (past generations) is half multiplier support: some motherboards couldnt handle it right, and even with BIOS updates, they gave out some really whacky ram speeds due to not fully supporting it.

Sorry... Just an assumption really. Every board listed there has 700 or 750SB and the M3A32 doesn't so I figured that's why.

yeah i said that didnt i? about power limmits?

in this case the new chips use LESS power then the current ones so thats not an issue.

as to multi's in my exp, alot of that was the bios, i had 2 boards that had that problem with the first few bios, and you STILL get weird memory clocks with many newer boards at half multi's, just due to how amd's chips work, not really a big issue, infact a few times it was a good thing because i was able to get a little extra out of my chip where i wouldnt have been able to if the memory devider was proper(could get ram to its max and cpu to its or damn close for best balance)

if the chipset mattered you wouldnt see any 700 boards with am3 support, since the 700 is really just an updated 700, the 750 has some fearther improovements that make it better for clocking in some situations, but nothing really "drastic" from the specs i read.

700 has a clock bug that in some cases causes problems with raid when overclocking, again nothing most people would notice or be effected by.
