So yeah, then the initial goal should be as follows:

FSB = 400
Multi = 9

9 x 400 = 3.60GHz

If that stays under 62C or so on full load with both cores (run prime95 twice; one instance on each core), then tick it up 2 notches on the FSB at a time.

Memory, obviously, run whatever divider will get you to DDR ~1100Mhz. Don't tighten timings until everythign else is stable.

Attempt to hit 650Mhz Core on each vid card. Tick higher if stable.;

Attempt for DDR 2100Mhz on the vid card mem - tick higher if stable.

If all goes well, then maybe try dropping your multi and raising the FSB even more to compensate.

On my system, all other variables being equal, using a FSB increase versus a multiplier increase gave me about a 3% gain in points with the exact same net processor speed. It should do even more for this setup considering the massive FSB bottlenecking occuring.

i scored around 15k with 2 8800GTX superclocked(stock speeds) with e660@3.4ghz. You score is definitely way too low for what you have.

At The Very Least Your Score With One 8800gtx On 3dmark 6 Should Be At Least 14k+ If You Have Two On Sli You Should Be Getting Around 17k+

CHANGING YOUR PROCESSOR WOULD GREATLY LOWER YOUR SCORES EVEN IF YOU HAVE YOUR e6600 OVERCLOCKED MORE THAN THE QX6700 THE QUAD CORE IS STILL MUCH FASTER. MY FREIND HAS HIS DUO CORE AT 4GHZ AND MY QX6700 AT 3.2 IS STILL FASTER BY FAR ON BENCHMARKS .SO I RECOMMEND TO STICK WITH YOUR QUAD CORE ...

Tsk tsk. Please don't post in all caps. Thanks.

In 3DMark06, yes, the Quad Core wins. In other benchies, and in most current games, a higher clocked dual core wins.

Can I make the suggestion, Nitteo, that you edit your original post to show that you hit close to 15,000 when you OCed your proc?

Underneath the cooler we have a G80 core on a reference PCB/memory design. Despite the reference layout the cards detailed specifications are anything but reference. The core is running at 650MHz, this is 75Mhz more than the GTX's reference 575Mhz. The memory clock on the XXX is an incredible 2260Mhz, around 460Mhz faster than the stock GTX (20% increase). As with the GTX the Ultra uses a 384bit memory bus and GDDR3. The memory chips used on this model are Samsung K4J52324QE-BJ08 and rated at 0.8ns/1250Mhz. Finally we have an increase in the shader clock from 1350MHz on the GTX to 1620MHz.



These are hugely impressive statistics and that's probably understating things quite considerably! So how does this compare to the reference 8800 Ultra, here's a quick run-down:

when are ppl gonna accept the fact that sli is not worth it. from what i have seen, this has been proven/stated numerous times, as it just was again

errrr no its not....

I had the QX6850 at 3.55Ghz running benchmarks
and I have the 6600 at 3.85 running benchmarks

What you have written is a massive generalisation.

The quad does better in 3dmark06 (see this is called being specific) because it scores highly in the cpu test, bloating the score out.
All the other tests in the benchmark will actually be lower because the 8800 cards prefer the higher overclocked chip.
So...my 6600 at 3.8 will score better than a quad at 3.4 on all other tests apart from the CPU test.

New Silicon

While the GeForce 8800 Ultra is based on the same G80 GPU as the GeForce 8800 GTX, it uses a revised G80 silicon. The new silicon, and the 90nm process used to create it, had been tweaked by NVIDIA and TSMC to improve timings and clock speeds.

In other words, this is the same GPU, only tweaked to run at faster clock speeds and lower timings. This revised silicon also has a slightly smaller thermal output. Although NVIDIA was not forthcoming about the thermal dissipation of this new GPU, they did say that the new GeForce 8800 Ultra graphics card will consume slightly less power (2W or 1.13%) than the GeForce 8800 GTX.

NVIDIA also did not say if the same improved GPU will be used in current GeForce 8800 GTX, it stands to reason that NVIDIA would switch the GeForce 8800 GTX to this improved GPU, instead of maintaining the older silicon. If so, new GeForce 8800 GTX cards will have real overclocking potential.
