890FX is AM3+ Compatible?

[SkullCracka]

ya first round probly will not utilize those pins makes since. not gona jump on that waggon this time though since i just got a 1100T yesterday. first round im scared of since the what were the models 9600 and 9500 eeek then got a 9850 that wasnt much better.

I just read a response from JFAMD

AMD is not supporting BD on AM3 sockets. Period.

Ok, so officially, there is no support, however, using that tool I mentioned above, it will fit!

Maybe we will get unofficial support from AMD's partners.
I just find this odd that all the mobo makers are saying yes, and AMD says nope.

So any instability problems that may happen amd says "we do not support it, if motherboard manufacturers allow for them to be used in older boards it's not our fault" or something similar.

[Halk]

Ths really suits me. It means I can go BD right away and then pick and choose the best motherboard - or stick with the IV Formula if the new boards don't offer anything.

Ok, a little more info from kinc

Featured AM3 processors such PII X6 uses 938 of 940 AM3s connection entries (two of which were never and are not routed by default, except the cards ASUS lists in their press release). AM3 + socket has 941 connections. AM3 + CPUs, however, has 940 connections, the exact same number of AM3 socket. Hence it is suitable even reasonable physical. Just be aware that it "only" works in practice with the motherboards on ASUS list.
Important to say is that it's only those who work when they have the correct routing to the power circuitry to operate a AM3 + CPUs.

So there you have the explaination to why it doesn't work on ex: gigabyte boards before v3.1
Asus has routed the extra am3 socket pin-holes on the listed models, where the other manufacturers have not.

It doesnt matter if AMD don't support it. They didn't support core unlocking on the 800 series but the motherboard manufacturers still managed to implement it

Whats important is that the motherboard manufacturer will support it - And in this case Asus have made it clear they will with certain boards (and the beta bios proves they are working on it)

So everyone but Asus was being lazy... nice.
GJ, Asus, really. I would be really glad if I had an Asus board right now.
Looks like we can dismiss all the doubts about the new CPUs working in the old boards right now.

Its pretty much the same thing i have going with the Foxconn A79A-S ,1055T works fine, but turbo and cnq work like crap.But setting everything manually works like a charm.
AMD screwed up on this one in my books.They could just say that the official launch platform will consist of 9xx chipsets with AM3+ sockets and backwards compatibility while possible will be in the hands of mainboard manufacturers (which was anyway always the case with backwards compatibility).
Instead they went
1.Yay! AM3 will support BD`s go ahead and change from your current am2+`s!
2.Were sorry guys, it wont, we need new socket/chipset combo for it to work.
3.Actually we dont need new socket or chipset, even 7xx will work, however we wont tell you that, its gonna be a press release from a mb manufacturer(maybe).

Thats messed up.

EDIT and BTW.
It makes me a customer for future asus boards tho.Thumbs up for them this instance.

I don't understand why AMD want kill one of the best features that they have (platform compatibility), Intel says officially that IB will be supported by SB mobos, so, if AMD goes in this way is like kill himself in the market.

My current mobo is a Gigabyte 890FXA-UD5 Rev. 2.0, but the Rev. 3.0 says AM3+ but with the same 890FX and SB850 chipsets. Here are the pics.



Same chipset, so, that's no the problem for not be compatible.

If BD isn't compatible with my current mobo, I'll have to buy a new mobo soon.

And now its clear. Only one mistake from KINC...AM3+ socket = 942pins, not 941

its not! Looks at, ASUS made for 3/4 years AGO Cross IV Formula with activ all socket pins (940), normaly has AM3 socket only 938 aktiv pins, because Thuban and Denebs need 938.
And now ASUS know specifications etc and they have a few AM3 models with 940 activ pins in socket. There is the diferent. Very prudent move form ASUS.

PS: I have Cross IV Formula and new Extreme, but for Zambezi I want new one with higher performance for Bulldozer.

[NEOAethyr]

Somene had posted before that there was some kind of wattage increase on the next gen chipset?

If that were the case then wouldn't the 890fx be the better anyways?
Runs cooler, uses less power, has same functionality, etc.

[XRL8]

As for the northbridge, my bet is that its exactly same chip, just with enabled iommu which by default was off on most 890FX mainboards, and that slightly increases chipset load.
Same functionality with same process node leads me to believe that.Also, am3+ doesnt require new chipset (and im talking about proper am3+ socket mainboards, not just AM3 with a bios update)
I would be glad to be proven otherwise tho.

[Oliverda]

a speculation by me:

[charged3800z24]

See, I had this dream last night...
May be they wanted to launch Bulldozer based desktop chips earlier but there was a 990series based boards with chipset issues. manufatures, Like Asus, decided to gear up for 890 series support to keep from any further delay. After testing is finished, AMD will decide to do a suprised early launch of Zambezi CPUs...

oh well...

ASUS is one of the few board manufacturers that enables the use of unregistered ECC ram in it's bios. Most (maybe all) of the AMD cpu's support it, even non-Opterons. Other manufacturers just don't go to the trouble of enabling this capability in the bios.

So I would give ASUS a double good job.

[MacClipper]

Here's a thousand words.

[BeepBeep2]

Here's a thousand words.

How is that possibly a thousand words? Everyone knows the Deluxe5 is an AM3+ board

[duron]

^ yup! it's on the first page already :P

[saint19]

a speculation by me:

Can you see the difference? I can.

[Oliverda]

Can you see the difference? I can.

Actually I created the picture. So the answer is yes.

[zhadoom]

At Gigabyte Website a new AM3+ section with various boards based on amd 890,880,870 and 770 chipsets.

MSI have announced AM3+ compatibility for some boards too:

I saw that a couple of days ago too. Kind of exciting news , but then again we'll have to wait until June to know for sure. That would be nice if it were a definite though.

[duron]

^ why would they advertise that those mobo are AM3+ OK if it was not definite?
