Bulldozer need AM3+, not compatible with AM3 board.

[JF-AMD]

AM3: AM3 processors - yes; Bulldozer no
AM3+: AM3 processors - yes; Bulldozer yes

There is no way that BD will work in an AM3, there is nothing to "shut off"

[Mechromancer]

I will definitely wait for an AM3+ motherboard then. Guess I will get a 1090T for my AM2+ system now, get the AM3+ board and ram together next year, and then get a Bulldozer later in 2011. The most important question now is when do AM3+ mobos come out and will they come out well before Bulldozer?

[wuttz]

this plan to have AM3+ incompatible with AM3-
is it mostly a marketing or engineering decision?

i dont see why AM3+ BD shouldnt work with AM3,
since the pinouts/power requirements are just about the same.

I am not a client guy.

I have tried to stay out of this and I need to bow out of this thread. The statements above are all I can say.

I understand...

stay cool guys, it doesnt look bad

[wuttz]

thank you anyway jf.
i really think that since BD is a compelling new uarch,
a lot of independent system builders/enthusiasts will be making new AMD builds in 2011.

but as for OEM's where a large chunk of sales go to, i bet llano/ontario/socket FM1 will make up the majority of profits instead.
either way, i see this as AMD playing its hand on maximizing profits.

( hey, AMD needs to make money asap.)

Isn't the quad channel coming from two MCMed chips each having it's own dual memory channel controller? So there is no way AMD would put MCM chip in desktop space, thus we should stop that nonsense about desktop 4 channel controllers. Who needs them anyway? Today we can clock CPU NB to 2.8-3ghz which is more than enough for 1600Mhz ram. I suppose BD will have higher clocking NB and support way higher clocked RAM, thus there is no need for quad or triple channel controllers

each module in BD can be power-gated.
perhaps the modular power-gating is what makes BD AM3 incompatible?

ps. look who i found!

Modular power gating hey.. I'm thinking exactly the same thing. I called it "fine grained power management" (including refined turbo) in my post, same idea though. If AM3 CPUs work in AM3+ motherboards, but BD CPUs don't work in AM3 boards (like JF confirmed for us above), this is the most likely explanation.

[mmarq]

I wonder what are those new features, though? We know turbo core is an existing feature and once it's setup by BIOS the CPU takes care of the rest, so it shouldn't affect socket compatibility. Maybe additional or faster HT links? PCIe? More power planes? ......

just an example..ok!?

botom line: turbo might not be the cause... neither power gating!... Asus turbo unlocker actually surpasses the original one for "thuban" most probably by "programing" the power microcontroller for more push!...

It even has the possibility of unlocking a core in those 3 core CPUs.... for a full 4 core CPU(many had sucess)

power planes isn't the cause either, this boards implement more that the ones needed for the CPU... and the socket is AM3 (+)... physically the same socket with the same pins!... or no!? (it must, either wise AM3 CPUs wouldn't work on them)

I wouldn't be surprised if we could see yet a version of Asus AM3 with "BD unlocker"...

just a thought...

One question i have... i'm not really a fun of OC.. if we OC a thuban with the "FS HT" frequency.. not the multiplier because the chip is not an unlocked BE... we lose the possibility of "cool n' quiet" ?
.. that is the CPU will never "throttle" down while with this OC ?

[Pietro sk]

ah taiwan mobo makers...
maybe they will find workaround about bd in am3..
they are capable of core unlocking and other crazy stuff

Having just invested in a nice AM3 board and a 1055T earlier in the year I can't say I'm too happy about this....but I knew it was somewhat of a gamble to take. Guess I'm just wondering what possible upgrade scenarios I'll see going forward. Kinda seems like AM3 at this point would be considered a 'dead' platform for much in terms of future releases.

Only thing I could see are future Thubans with higher frequencies, and even then it seems like the number of those would be very small.

[muziqaz]

well at least AMD had a guts to come out 1 year in advance and say that they will release new socket. I was thinking on buying couple of am3 8 series motherboards, but stooped my plans when I heard the news. If AMD waited till later to announce it, I would have gone on buying my two motherboards, now I will just stay put with what I have now and wait till next year when they start releasing bulldozer compatible motherboards.

Thanks JF.

No need to say more. It's a new architecture. It's not a current processor that has been either speed up and /or refined in some form.
