Could it be typical misspelling or there is more into it??
I'm almost certain Phenoms B2,B3 will work on AM3, but old Athlons or Semprons??

PS. Just noticed another wired misspell: "AMD PhenomTM FX"

[chew*]

Hard to tell is there a better picture? it looks like that has the extra pin for am3.

EDIT thats definitely got 941 pins. Now if the info is accurate then I guess my source is preety reliable

[G0ldBr1ck]

that is weird, if thats true it means that AM2, AM2+ has had DDR3 IMC the whole time........tho im guessing its an error

[flippin_waffles]

Bluetooth has a first look article up on OCW claiming this board supports DDR3 1333. There's also a review there of the DFI LP Jr with a PII and 9550.

[G0ldBr1ck]

why does the PCIE switch card say SLI/Xfire? do they just use the same card on diffrent platforms?

[FischOderAal]

Not remotely possible. No AM2 or AM2+ proc supports DDR3 yet (only Deneb will). AM3-procs fit in Socket AM2(+) but it doesn't work the other way round.

Well, that's what we've been told for a long time now.
Recently though I'm hearing more and more hints to the opposite

I know it doesn't seem likely, but just look at the socket. First we heard that AM3 will be 938 pins which would automatically locked older AM2(+) 940pin CPUs from fitting into it. Now we know that AM3 is 941 pin and there is nothing physically holding older AM2(+) processors from being plug into it....

I hope 9 Jan we will know for sure

AM2+ processors as Deneb only .No other AM2+ CPU has DDR3 capable IMC (apart Barcelona/Agena which was never "functional").

edit: Ok i've just read the specs for this board and I'm perplexed?! The board is DDR3 only and the list of CPUs supported extends to AM2/AM2+ K8/K10 based dual cores/QCs,wth?!? So according to Asus,even K8 X2s can work with DDr3 memory since the board doesn't support any other DRAM standard apart from DDR3 one.It's getting interesting by the day... Either AMD had DDR3 support with RevG/F from the start or someone at Asrock made a fubar mistake

[aGeoM]

My feeling was right http://www.xtremesystems.org/forums/...1&postcount=35

What I didn't expect, was the Athlons and Semprons working at DDR3.

Well done ASRock/AMD.

[azraeel101]

Maybe AMD can use the same IMC for DDR2 and DDR3, only a bios update being needed? Kinda far fetched, but it could explain this thing...

[justapost]

Would be amazing if they can add DDR3 support to AM2 chips with an microcode update!

Specs say tripple crossfire. The switch card says 1x16 or 2x8 so I assume tripple crossfire will be 8x8x4 then.

I like AOD790GX/128M may stick with asrock on am3 also.

I'm missing mouting holes for an pwm cooler, but never had issus with a fan on that area.

AOD used DDR2 for the sideport mem I assume M3A... will stick with that. So onboard gfx speed is abit slower than for example the gbt790gx with faster ddr3 mem for sideport.

Thanks for sharing Lightman

[demonkevy666]

IDE connector lol such an odd placement.

it' also says shared memory 512mb and side port 128mb ? wth ???

Here is a bigger pick, and the TM is for trade mark on the Phenom name. Note the board actaully says DDR3 1333 on the right side of the board.
Also, right below the socket it says AMD_AM3, and "something"_AM3

[Cybercat]

If an AM2+ CPU could do DDR3, what would be the point of the P2 925 and 945?

how about higher ram speed support.

[flippin_waffles]

I wonder what fast DDR3 would do for something like FASN8.

[Daveburt714]

I'm assuming you guys have noticed already, but the "keys" on those memory slots are definetly DDR3. I checked it against the DDR2 slots on the Asus 79-T...

So either Tweaktown or Asrock totally borked the abilities of this board, or aGeoM, myself and a few others were correct about AM2+ chips (even B2) having an IMC capable of both memory types....
Hell, They even listed DDR3 registers/controls in the B2 white papers back in 2007.

I agree 100% about the Athlon/Sempron chips.
But, at least to me, it would make sense for AMD to plan ahead and have chips capable when DDR3 prices come down...

I'm no engineer, but I don't think the IMC would require that many more transistors to support both mem types...

[cdawall]

hey not burst any bubbles but the name of the mobo is photoshopped onto it


and isn't DDR2 pinned the same as DDR2? maybe its goign to be interchangeable? or maybe the change from DDR2 to DDR3 isn't enough to warrant a new mem controller or there could be new sempy's and A64's coming out for AM3 thats my guess they can't all be phenoms

[kenofstephen]

The board......nothing special at all...

the controller is within the CPU, think about it.

Well, I can't comment on the photoshop thing.. I'll leave that up to other folks. But, DDR2 and DDR3 are not keyed the same way, so they're not interchangable.

DDR2 has the key closer to the middle of the slot, while DDR3 has it more offset to one side.

Heres a link to a pic of the Asus 79-T. If you compare the pic to the Asrock board you can see the difference in the key position..

But yes DDR2 is pinned the same as DDR2...

i tohught they were keyed the same woops thinking lappy ram :p

and nice catch on my typo

[Daveburt714]

I understand that man. What I was trying to get too was the fact that the boards specs says it supports AM2/AM2+ and AM3, and yet all Mem slots on the board are keyed for DDR3 memory.

Who knows? I'm not going to insist that I'm right, only time will tell..

But it appears that alot of chips have an IMC capable of DDR3 memory support. Athlon 64's and Semprons seem kind of pushing it to me, so it may be a typo or pure BS...

I still belive ALL Phenoms have an IMC capable of DDR3. Just my opinion...

[cdawall]

on OCW now

buying board with a "AM3 socket" is the only way to ensure.

Thanks for bigger pic Charged!

But in that bold Phenom name I was after FX moniker and not TM . This is another source mentioning return of FX
