The i7 will definately push your results a little more if clocked +5GHZ.
Another thing that I recommended to some pages ago was the 4Pin connector for the PCI area.
I am sure that if you connect it the increased PCI area stability for your cards will give you a little more headroom for your OC and keep it more stable in general.

950MHZ for Tri SLI Ref cards ir great, really.

Lastly, don´t be lazy and post the results in the format required [ ]

Other than that, great job

Your results will be updated.

If this were my club, I would eschew the use of Vantage 'Performance' mode, and make 'High' the 'standard' for the club.

Reason being, even the GPU score in Performance mode is HEAVILY impacted by CPU when you have SLI 580's (let alone tri-SLI or more). It probably makes a small difference even w/one 580. It's simply too old of a test, too easy to run ... for this much GPU power.

Basically, it runs so fast with cards of this caliber that the CPU starts to bottleneck due to the high FPS, esp. on test 1. And that shows up in the GPU score.

With High mode, however, the difference in GPU score between a stock 920 and an SB at 5.0GHz is probably only going to be like 1K points at MOST, even with SLI 580's (might be a bit more w/tri-SLI).

So, by using High, when tabulating results at the top, you get GPU scores that can be easily compared w/one another w/o having to compensate for CPU speeds all the time

'Extreme' mode, of course, would be even better, but unfortunately since Vantage came out, the entire world went 1080p crazy, and almost nobody ended up migrating to the (far superior ) 1920x1200 monitors.

Not being critical, just throwing it out there ... never too late to add another category

guys sadly my son decided he has other plans then me today and got up at 6:15 in the morning... needles to say i hadnt had time to take many photos, so here is a teaser and ill post the rest in the evening still i must say that its been a pleasure setting up wc in this case and I cant believe how easy and quick it was

wermad: I see you took it seriously bro and you keep pushing them very nice scores, now head for 980 im gone lay off benching for 2-3 days till i get enough tim then im gone freeze one of my lightnings

kung pow: I live to serve and spread the name of one true faith.... OCN Overclocking Team above all else btw im after taking the leap and moving over to the Xtreme Overclocking League on HWBOT only downside is I dropped from 15 to 223 but all in good time this week im getting my 5800mhz chip that plus the 2400mhz ram should boost my scores a fair bit

Actually that is brilliant.

Currently there aren´t really many benchmark options availble in order to determine one card´s maximum
I tried to orientate on HWBOT a little though with the choice of our benches.

I chose Vantage out of 2 reasons.
It is currently with 3DMark11 still one of the most popular and used benchmark media online.
And even though especially considering a GTX 580 the results it may bring are not as accurate as with 3DMark11, due to its popularity most people still run it and in order for our club members to be able to compare to most of them I have to offer it the same way the majority runs it.

The influence of the CPU is the negative factor though, yes.

But I figured out something in order to clearly determine the CPU influence of each members CPU with their scores
In my Benchmarksheets in which the scores and therefor CPU influence problems will become more relevant I have created an extra column for the members CPU type and speed.
Since all members are required to post a screen of CPU Z too that isn´t a problem to find out.
Now I have started working on creating a graph based on all the information I have gathered so far from members in possession of LGA 1366 and 1155 from 4GHZ-5.2GHZ in order to measure the influence of the CPU.
OF course for that I had to take in account the members RAM, board,GPU of course, applied OC, cooling,CPU OC, etc etc in order to create an accurate pattern of how the GPU scores of people with higher CPU OC behave.

From what I have gathered so far it clearly shows that not the CPU type is the most relevant for this issue but the extent of the CPU Overclock.
Also it seems that the cooling of both the card and the CPU is highly relevant.

Still this is no scientific analysis which could possibly deliver absolute and 100% accurate results, but I do believe that through this method at least a certain pattern is clearly determinable

Offering an Xtreme preset though isn´t a bad idea at all.
I will consult with our members and ask what they think about it

I am too
For Tri SLI this is absolutely great
And the scores speak for themselves, obviously

You are a beast
Extremely looking forward to how to GPU will behave among those circumstances

Also, seeing your pictures makes me wanna get a bay res too
My fittings suck ...got I love those Bitspower compressions
Really nice job on the tubing, and color theme so far
When I get my PSU already I will surely challange your build^^
Mine is white/green yours is black/red

Edit:sry doubler...thought I was editing

thanks bro and its on, challenge accepted im collecting ideas about what could be changed or improved in this build which psu did you go for? btw did you notice the mounting screws on the K370? they are my ss units screws with the backplate for the mb and everything and they actually fit so when ill want to bench on the ss i just need to disconnect the cables, take the block off (ive left enough loose tubing that it comes off np reconnect cables and put the ss block on (insulate the cpu socket) and im ready to go

Update needed on my entry =)

[Skoobs] [EVGA GTX 580 Reference] [955/2070@1.100v] [ID30c/LD50c]



i have decided that the cards are not what is limiting my overclock- i believe that it is my settings in the BIOS or something. I am not sure what settings affect the GPU overclock though... probably the PCI voltage or something, but i am terribly noob at this stuff.

also, i noticed that there are two #19s and #20s on the spread sheet. is there a reason for this?

First of all we are a polite club
*Update please

Secondly, there are many things that could manage to inhibit the GPU in its performance.

I would start with the most obvious and common problems.

1.)A too low GPU overclock in most cases causes a GPU performance loss also known as bottleneck , so a corresopndingly high CPU overclock benefits the GPU performance greatly.
With your 950MHZ on the core I would recommend your i7920 to at least be clocked to 4GHZ+ since that is the absolute border.

2.)Secondly, there is of course the aspect of instability.
An unstable GPU overclock can cause performance flucuation and in the worst case loss.
So make sure through various benchmarks and stress tests that your GPU overclock is absolutely stable.

3.)Also, often the case is the software environment most people tend to forget
Make sure that before every benchmark run you close all other running processes and give the bench process the highest priority in the task manager.
This should ensure no other programm eating up resources during the run and letting your rig take full focus on the bench that is being executed.

So please check those points, if none of them apply we will dig deeper and find out the problem

Your entry will be edited .

Edit:sorry I read you had performance problems, just saw that you wrote OC limiting.
Here the question of what is causing it is a little shorter^^
The GPU OC itself is completely determined by the core and marginally by the cards power inductive means and abilities.
So up to the point your card shows artifacting,display driver crashes , performacne loss and no voltage increase can help your core has probably reached its maximum OC.
The CPU and other means are only relevant to the scores though.
The correct driver could just play a small roll too though.
Currently the most oc friendly driver is the 266.
