Finally a SB750 review

**robbicfc** · 07-21-2008, 01:09 AM

Hi All,

Kinda anyway. Full review is out tomorrow.

looks promising so far..

**largon** · 07-21-2008, 02:01 AM

Indeed. Looks good.
I'm gonna wait for 45nm CPUs until I dump this stupid Intel LGA775 platform & Q6600. I'm getting really tired of FSB, Intel's MCHs & the BIOS architecture of LGA775 boards. No more Intel for me.

**robbicfc** · 07-21-2008, 03:13 AM

The way I look at is it this way. If it helps Anandtech broach the 3Ghz barrier or 3.2Ghz in this instance then some of our more Xtreme members might even push 4Ghz

**Phenomenalspeed** · 07-21-2008, 04:52 AM

Nice.

Some good news. I thought that this new feature Advanced clock calibration was reserved for AMD Overdrive only. It's good to hear that it will be incoporated into BIOSes as well.
That should hopefully mean that the overclocking boost with Southbride 750 is not available only in Windows.

It will not help that much, if your CPU is already good, might see 100~150MHz out of it with some individual core tweaking. However, you will be able to run at lower voltages and higher NB clock speeds. It works best on those CPUs that have been poor overclockers, seeing about a 300MHz increase on a old 9850BE that would not do more than 2.7GHz today.

I really hope these SB750 boards improved overclocking is also present via BIOS.... I dont like AOD AT ALL.

Yeah, AOD is totally flaky. The idea is nice, but man oh man, each time I use it, I never know how its gonna turn out. It crashes the system more than I can even understand.

**D-Cyph3r** · 07-21-2008, 11:24 AM

Jesus, tell me about it! I can literally touch nothing other than the CPU multipliers and when I hit apply the HT link or PCI-E would just randomly shoot up into the red, giving instant BSOD goodness.... wtf is up with that?

Like you mine is watercooled, so I really want to get the most out of it (even if it takes 1.55v+, the cooling can take it). :/

Bingo can you confirm for me that the test on Anand was done under Vista x64? If that's the case then SB750 finally is bringing parity to overclocking under x32 and x64 systems

Yeah. It drives me crazy. Mine exhibits the exact same behavior. Just the multiplier works. Everything else is simply wrong, erroneous or broken. Something is just plain wrong with the software, I'm not sure what. NTune on the Nvidia boards sucked also, I had those for years.

I suspect that its written by AMD and is expected to run on every motherboard is part of the problem. But honestly, I only used it to fart around with limits. I still do everything with BIOS anyway, even though it takes longer.

**Particle** · 07-21-2008, 12:52 PM

The implementation is probably where the real fault lies, not the software. I know the software is the visible piece of the puzzle and thus is easy to blame, but it just doesn't seem correct.

**Tom128** · 07-21-2008, 01:31 PM

I have been waiting on a motherboard upgrade for SB750 in the event that the hype was real. It seems to be. I wonder how much longer it will take until a 790FX board is paired with it? That is idealy what I want, however from some articles I have read the 780GX also seems to be a potentially good overclocker. Any idea if those boards will have more than 5-phase power? I would LOVE a uATX mobo that I could push a phenom in. I want to make a nice travel computer

The Foxconn A79A-S being tested by Anandtech IS a 790FX with a SB750. We might see these BEFORE the GX boards.

I hope so... I want one NOW. And yes... it does seem that what some people considered the AMD smoke and mirrors show is ACTUALLY going to be something that might make some people green with envy.

Yes, Vista 64 is the OS of choice with 4GB of memory. I have not noticed a real difference between the two operating systems yet, testing Vista 32 right now.

**MrMojoZ** · 07-21-2008, 03:39 PM

Good clocks on Vista 64 is pretty important to me, hope the 750 solves that issue.

**MoF** · 07-21-2008, 10:05 PM

As posted by macci a few days ago at muropaketti.com:

17071
(screenshot)

Phenom 9600BE @ 3360 (210x16) 1.55V
CPU NB = 2520MHz
RAM = 560MHz CL4-5-5-15-16
2x Radeon 3870 GFX @ 945/1310
AMD "Betta" (SB750)

Pretty nice OC for a 9600BE...

**largon** · 07-21-2008, 10:46 PM

MoF,
And the cooling used was ?

As may be seen via the compareurl, Thermalright Ultra 120 Extreme.

The GPUs were with stock cooling, so aircooling all together.

And the system was inside a case (Antec 900)

**ChristmasGT** · 07-21-2008, 11:36 PM

Woa.

That's also a lot of voltage on air, but still...WOA.

Also any word if thats a BE or just a normal 9600?

BE. Just look at the multiplier.

**ChristmasGT** · 07-21-2008, 11:44 PM

That's just so much voltage for Air though, I wonder if we're seeing those 6 magic pins in action?

9600BE, as already posted on the first post about it.

The voltage is 1,55. Not 1,65 and not 1,25 as someone might think of the screenshot.

**ChristmasGT** · 07-21-2008, 11:52 PM

1.55 isn't too bad at least hes got great air cooling, I wonder how much tweaking he had to do to get it that high. I'm really hoping Anandtech goes deep into it today
