Been playing with 2600K today on a Gigabyte P67A-UD4.
Currently @ 4833MHz 1.37Volts

And this thing loves the SLI setup and/or probably Xfire.
OC is far too easy, move the multipier up the voltage. Done. Gone are the days of tweaking and FSB adjustments.:mad:

My GFX card SLI % usage has moved from 80-95 into 90-98% and it shows.
I5-750@4GHZ vs [email protected]
800-1800 SLI 470GTX

More benches to follow.
 
Sorry to go off on a tangent Skyrocket but been thinking about going for the P67A-UD4 over the Asus P67. Did your build go smoothly? Any problems with the BIOS, stability in Windows etc?

Fair enough there has been a lot of talk amongst members going for the Asus and subsequently problem posts with Asus P67 builds which has me concerned but thought I ask anyway. Thanks :)
 
Yeah SLI/Xfire love a fast CPU, not so much single cards, once you whack up the AA CPU speed is less important, well 4.8Ghz is not necessary IMO for 24/7 use but still a nice overclock. 1.37v, OK for benchmarking but no 24/7 running on the 32nm chips, hell I don't like running my 920 Do at 1.37v for 4.4Ghz when benchmarking.
 
thought some people were haven problems cooking these cpu's in that section there is a thread on it they thought it was tied into memory voltage or something, good to see its only a few that are affected.

No problems with the P67A-UD4. Using f5 bios and its smooth sailing.
The mobo does have 1-2 probs though.
A) Front audio plug is right by the rear IO ( Why so far away I will never know )??
B) CPU fan control is possible but not SYSTEM FAN which is a bit annyoing.
C) No IDE connector on the board.

Apart from these minior faults the mobo is rock solide and stable with 8GB of Ripjaw memory.
I dont need EFI bios of ASUS I perfer the old style bios, and I perfer the all black mobo design.
Quality board.

Intel says that anything up to 1.4 should be fine.
I think 1.4++ you could start cooking the cpu.
I am also keeping my memory low as I can at 1.5V @ 1887 9-9-9-24-CAS1mhz.
I will probably back the baby down a bit.

The 266.35 drivers explain most of the Heaven gains. These work extremely well for SLI and gave me a nice 10fps for my GTX580-SLI over the old 260.99's. CPU makes very little difference. If I clock my 950 from 4GHz to 4.5GHz it makes less than 1fps difference.

Try reloading the old 260 drivers on your SB and see.

edit: Sorry, just checked and the gain was 6fps for my 580's and not 10fps as posted above. Still a nice gain for a driver refresh.

And how many hundreds of pounds did you spend for that extra 5 min fps?

Faster computer is faster, and captain obvious is obvious.

Bleh I'm not kidding anyone here, I'm just jealous ;) Nice rig you got there.
 
To be fair it would be a useful comparison were it not for the fact that practically everything has changed between the two systems. The CPU is clocked faster, the drivers are different, etc.

EVERYTHING is CPU dependant, not everything is CPU LIMITED.

Benchmarks are variable, they don't have a constant FPS rate thats 100% gpu based, there are ups and downs, cpu limited and gpu limited parts, at some stage most benchmarks will have points that are CPU limited, where either something ultra complex is being done on the CPU and minimum framerates can be improved by that being done faster, or the opposite end of the spectrum and easy scenes where the gpu is only limited by how much data the CPU can churn out which can limit max frame rates.

Considering of course you've changed mobo, cpu, drivers its rather pointless as it could all be in the driver, it could be slower with the same driver, or faster, who the heck knows.

I really really wish people wouldn't use Uniengine for anything though, its a benchmark, nothing more or less, doesn't tell us crap about the 480gtx vs the 5870, doesn't tell us anything about the 5870 vs the 6870/6970.

GO benchmark a game, before and after an upgrade and see what the difference is, it seems only to have become the standard on OCUK as it was a heavily company dependant benchmark(amd vs Nvidia) so gained traction.

It needs to be banned, at least till theres a ridiculously good tesselated game out.

Sandybridge seems nice, even if mobo choices are horrible(not individual boards, the fact you pay for a gpu but to overclock you can't use it) but gaming performance, is sli faster in say Crysis with a better cpu at settings you'll likely use.

If the Z68 mobo's were out now, and were sanely priced(expecting they won't be :( ) I'd be soo tempted to pick up a 2500k/mobo combo right now.

Maybe if you did OC your CPU you would have the chance to see a difference for yourself

Ok, OC cpu from stock 3.0Ghz to 3.4Ghz and heaven scores changed as follows:

FPS: stock = 40.4 OC = 40.9
Score: stock = 1017 OC = 1030
Min fps:stock = 27.8 OC = 28.6
Max fps:stock = 82.8 OC = 83.6

So yeh you were right OC the cpu does make a difference, a very tiny one.:D

Yup 266.35 state "Up to 8% in Unigine Heaven v2.1 (SLI 1920x1200 4xAA/16xAF)" over 260.99.

nVidia seem to be working hard with the next couple of driver releases pushing SLI gains which seems to indicate to me they could be building up to the release of another "GX2" type card, looks like any leads CF might have in scaling will soon evaporate.

+1

If you're going to make comparisons between the cpus, make sure everything else is exactly the same. Particularly gpu drivers, as heaven is very gpu dependant as you say.

A clock for clock comparison and a max overclock comparison for both chips would also be nice, just to put things in more perspective :)
