Finally a SB750 review

[bingo13]

And also what was that about PCI-E 1.1 support only...????

I will go back and reword that probably, although we never had questions in the SB700 review about it. The 790FX/780G NB offers PCIe 2.0 support for graphics. The SB700/750 A-Link Express II interface to the NB is via PCIe 1.1, there is still plenty of bandwidth available, just that we have been after AMD/ATI for two years now to get that link up to PCIe 2.0 to match the NB.

Well I love AOD,really..
It just keep getting better and better, the only problems
with it was the beta (2.1.1) version.
It fully works on 2 boards including the M2r it also "works"
on the Asus m3a however the only sliders I can change are:
cpu,HT multy,and the cpu&NB Vcore.
Guys (and girls) with the M2r use the 2.1.0 version of the AOD
and make a CMOS reloaded profile with all settings at default.
I mean certain things you can only do with AOD: like individual
core clocking and adding certain voltage levels to the cpu.
I do use XP32 however maybe Vista+BIOS+AOD is the
problem not just: AOD is sh*t end of story....
Waiting for a DFI-790gx here ....

Hey any possibilities to test older b2 revision phenoms ? non be models ofcourse

[kazgirl]

i don't think it is the sb600 that causes that:you dont even have sb600

Sorry I should have mentioned, my sig needs updating my current system is:

Phenom 9850BE @ 2.9Ghz (1.475v) - 3.0Ghz (1.5v - not stable)
ASUS M3A32-MVP Deluxe
2 x 2GB G.SKill PC2-8500 RAM @ 5-5-5-15 2T
2 x GeCube HD4850's CF @ 700/1100
Vista Home Premium 64-bit
2 x 160GB Samsung Spinpoints (RAID-0)
1 x 320GB Seagate 7200.10 (JBOD)
Thermaltake Toughpower 750W PSU
Thermaltake PurePower Express 250W VGA PSU

So I have got the SB600 at the moment..

There is a PCIE1.1 link between the NB and SB, this is what Anandtech was complaining about. It's not a big deal as PCIE1.1 is PLENTY for the amount of data going through the SB. The Northbridge supports PCIE2.0 as always.

Phew I thought that I was eithre missing something or that there was a typo or something.... !!! thaks for clearing that up....

The SB700/750 A-Link Express II interface to the NB is via PCIe 1.1, there is still plenty of bandwidth available, just that we have been after AMD/ATI for two years now to get that link up to PCIe 2.0 to match the NB.

It would be nice to see, definitely.... even if it was just for future-proofing etc... not that such a thing is possible these days...

Yes I got v. 2.1.1 at the moment looks pretty and all that, and the diagram is a novelty touch... I've never used AOD much, it just kept causing too many inexplicable locks ups, just upping the vCore a notch and applying and it would lock up, needing a reset... got fed up in the end... but maybe it'll be time to give it another chance with SB750...!!!

[illogical]

All I can say is WOW! wants one wants one wants one wants one NOWWWWW.
With luck this will put stinktell back where they belong, in mass market sheep products, following the leader in inovation into the next millenium and beyond.

[Phenomenalspeed]

Phew. So Andandtech have this confused?
I was going to say it's no bloody good giving with one hand and taking away with the other.
Upgrading overclockability and downgrading Graphics card potential.

So PCI-E 1.1 is between 790FX/GX and SB750?
I actually thought it was Northbridge------ Hypertransport----- Southbridge.

Why do you think that they kept saying "the thing that we dare not mention"?
It seems as though they are alluding to 790GX

Still no northbridge multiplier for AMD Overdrive though....

[Oliverda]

AMD's ACC Is Clock Skewing?

[possessed]

nothing i haven't thought also. not precisely that, but some control of the main cpu clock crossed my mind. So no big deal if it's that for me.

[Oese]

did imagine something like clock skewing.. makes pretty sense..

[Brother Esau]

LOL.........So more or less they are way behind in releasing a Vital Micro Code Update for Phenom . Well....Duh.... if we have not know that since the frigging Beginning of all this Hoopla Six Pins my ASS

[bingo13]

Hey any possibilities to test older b2 revision phenoms ? non be models ofcourse

Yes, will have an update tomorrow on the 9600BE, and a 9550.

That was my first question to AMD, no comment, in fact, we had a lot of no comments.

Its actually CPU->HyperTransport->Northbridge->PCIE1.1->Southbridge.

Really its not a big deal, Anandtech would like to see a PCIE2.0 link because Anandtech would like to see a bigger number. The southbridge only supports USB, SATA, PATA, Audio, and PCI. The 4 lane PCIE1.1 interface allows for 2GB/s of bandwith. It would be damn near impossible to use that kind of bandwith with these kinds of peripherals.

[informal]

Guys,don't ask me how i know ,but it's not "clock skewing" since that is related to memory channels.

[alexio]

Guys,don't ask me how i know ,but it's not "clock skewing" since that is related to memory channels.

Clock skewing is something that can be implemented on any bus (if the part that controls the bus supports it), so your argument is not valid.

[informal]

Yes it can,but it is not the case with K10 clocking and SB750.
Can you point me to a proof that Ed Stroligo's bs is valid?Thanks.

[kazgirl]

How do you know....????

But seriously it does make you wonder if its just not some strategy to boost their sales....

They were in a lot of trouble last year.... so...

1. Launch a crippled Phenom + RD790 with SB600 knowing that some would sell because of the wait for them...
2. Launch Black Editions which will then sell further and in all likelihood those who bought initially will also buy to replace the previously bought useless chips
3. Launch AM2+ mobo's with SB700, people with SB600 replace mobo looking for better performance
4. Launch SB750, and now utilise a hidden means of releasing the handicap of previous versions, people again buy new SB750 mobos, to replace their previous models

All this time AMD are cashing in with sales of mobos, CPU's being bought and then replaced,..... how many here can say they still have their original Phenom and mobo combination....!!!

I know I've changed 2 different Phenoms and at least 1 mobo..and will be getting a new 790FX/SB750 as well.... ..!!!

Of course theres no gain to be made from them holding back the Phenom any longer, as now there's an alternative choice in the shape of the NV 780a boards being available so all of a sudden the SB750 'magic' fix suddenly appears.... though all those NV780a mobo buyers will be cursing now, as having just bought their new mobo, its the AMD SB750 that releases this hidden perfromance boost with Phenom.... and guess what it suddenly becomes available as NV chipset boards are more readily availalbe...

It could all be a strategy....we see this kind of thing in the GFX cards market all the time, with NV and ATI , NV release one card to counter a card launched by ATI and vice versa....

Could it be that AMD have been holding onto their Trump card, waiting for NV boards for Phenom to be released before then releasing the SB750 to boost their own chipset sales...??????

Who knows....bit of wild speculation....been bored so my minds been racing...: Flights of fantasy and all that...!!!! But it could be plausible to some extent..!!!

HMMmmmmm....!!!!

Can you point us to proof that it is invalid? Ed admittedly offered an educated guess as to what these 6 "magic" pins do. All you have offered is "knowledge" that this isn't the case along with a statement that is completely untrue (that clock skewing is only related to memory channels).

If it is, its an idiotic strategy. Fact is AMD isn't cashing in, they are hemorraging money (search for their Q2 financial results). A healthy Phenom and SB750 at launch time would have probably helped stave off Intel's price war for a while and helped AMD make some money off these chips. The bug with the B2s cost AMD a LOT in the high-performance computing environments where they still had an advantage due to superior scaling in multiple-socket machines.

[alexio]

No I can't, but you did accept that your own point was 'bs' and that's enough for me. Ed's article isn't 'bs', it contains a well supported theory, but at no point he states that he knows the theory to be true. But it seems you do, so despite your rather silly previous comment I believe you, naturally

LOL... I agree completely... as I said total flight of fantasy, I've been feeling a bit idiotic today...

I appreciate you clearing that up.
Much obliged.

@ Kazgirl

2.1.1 is the beta "problem" version
My "AMD cpu stepping" is set to P0 as well.

Did you all notice the "new AOD" in that Anand "review" ?
The other "thing" that some people have "missed" is
the fact that we'll need less voltage for higher clocks

I still have m3a with the original B2 9600be in it btw
well and the 790m2r with 9850be

[ChristmasGT]

God lets hope this week they get released, this is murdering me!

[Mechromancer]

God lets hope this week they get released, this is murdering me!

Me too. There better be news of a mass release of SB750 boards by the end of the day! AMD needs to put up some solid release dates.
