Indeed. At this time, without your framerate report, I am going to have to blame your poor performance on the crap vista drivers.

Do the framerate tests and let us know.

.

I concur.

Hi there
its my first day posting here !!! hi everyone

Regarding to this topic, I have my E6600 @ 3.48 using Tuniq Tower with Silverstone 110CFM fan, temps idle 46 loaded 58 sometimes if my run is hot, may get to 60 wierd 61 but that only with orthos, no one single of my games/programs will stress the CPU like that, so must of the time is ~ 46 and 52

my Video Card is Evga 8800 GTX on Stock speed it was 60 loaded 75
i overclock it just for fun, because i am getting another one soon to do sli to 601/1007(2014) and Temps didnt change much now its 62 load 78

I get the memory Twin Corsair 5400 4 GB 4 stick 1 GB each, its overclock from 675 to 750
fsb for CPU 1500

I have no problem of stability at all, everything seens to be OK

my Case is Coolermaster Stacker, with 6 Fans 120mm 80CFM each
my power Supply is BGF 1000watts

I used ATi tools to monitor Video Card
and SpeedFan to monitor CPU
my motherboard is EVGA

any sugestion


CPU voltage is 1.49
FSB 1.4
Memory 2.00
everything else Auto

Chepin, welcome to HardwareLogic! :wavey:

As to your post, I guess I just can't quite get a handle on what exactly your question is. Could you clarify please? Also, what kind of gaming are you doing that requires 4GB of memory and two 8800GTX cards in SLI?!

[Chepin]

I play Battlefield 2
my monitor is 19inchs Xerox

my question is, if there anything i am doing wrong?
my first time overclocking, and I am afraid to damage something
but I follow Nvidia Guide of Overclocking, and Didnt pust further their recomended voltages

the Reason I add 4GB is because the place i buy the computer offer it with 4 GB, and the Sli is also part of the offer, for 4 000 us$ i think was good deal, so i buy it, they will ship me second Sli 8800GTX, because at the time of shipping, one of the card break a part (Thanks to the deliver company)
sorry my english I am spanish


thanks

Welcome to the forum. I don't think you should overclock those cards, at least not until there is a need.

I seriously doubt that a single 8800GTX is having a hard time running BF2 on a 19" screen. And two 8800GTX's?! That's an extremely good example of "overkill". But hey, you will be set for about any game that will come out for at least the next 5 years!

Well, the thing you really want to keep track of (especially on such a high-end card like the 8800GTX) is temperatures. nVidia's driver control panel should display the temperature of your GPU. If not, Rivatuner should. Rivatuner also gives you slider bars to overclock the core and memory of your card. If you really want to overclock it (which I don't suggest because you should be getting plenty of performance right now and there isn't much headroom in these cards), then start by increasing either the memory or the core clock by about 10 MHz (not both at the same time!). Once the speed has been increased, run RTHDRIBL and watch your temperatures. If they stay below 60º or 70º C, then that is a good sign. If they are higher than 70ºC, then that is pushing it and I would not suggest going any higher. Then run a 3DMark benchmark of some kind and do some gaming. Meanwhile, look for artifacts (odd jagged lines or geometry errors in the scene. EXAMPLE). If you see artifacts then that speed is unstable and you need to lower it down to your most recently stable clock speed.

So you will increase either the cards core or memory clock speed until your temps get too high or you get errors, artifacts, or your computer freezes. When that happens, record what speed it was, then reduce it back to stock. Then do the same thing to the other component of the card (if you were overclocking the core, then do the memory this time) until you find the highest stable clock speed of that part.

Now you should have two values, one being your highest STABLE core overclock and your highest STABLE memory overclock (both of which were discovered independantly of one another). Now, you will try to combine the two clock speeds for a total overclock on both the core and memory at the same time. Subtract 20 MHz or so from both the core and memory overclock speeds you found and set both at that value to start with. Now run your temperature testing and benchmarks for artifacts. If both complete without incident, then you can raise both 10 MHz and re-test. Continue this until you get instability, then back both the core and memory speed back 10 MHz just to give you a safe buffer and you have your highest STABLE overclock.

The biggest thing to remember is to watch your temperatures!!! Out of control temperatures for sustained periods of time will kill your card faster than anything else (except maybe forcing higher voltages to the card).

I post before, I raise the Memory and Core to 601/2014 Using Ati Tool and I use Ati tool to find artifacts, Temperature Without overclock are
IDle 60
load 75
with the overclock from 576/1800 to 601/2014
Idle 62
Load 78
Load for me, is using Ati Tool to find Artifacs for 1 hour or more
after running 3Dmarks the Temp on the card is ~68 72
either Overclock or not

how about my Memory and CPU are they OK ?
thanks in advance

Your memory voltage look fine, but your processor voltage is about as high as I would feel comfortable going. And I usually try and keep my processor temps at or below 50ºC and 60º is a too high for comfort. You might want to either lower your overclock a little to where you don't have to have the voltage so high or rework your cooling a little.

But we're starting to get off topic a little here with talking about your particular system's overclocking on all components. If you have any more questions regarding anything besides overclocking your 8800GTX, then please make a new thread in the appropriate section of the forums.

Raising voltage on video cards can be dangerous. Even with extra cooling most cards cannot sustain the stress created by hours of intense gaming with higher voltages. I say 10% max increase. Be careful.

I damaged a X1800XL with voltage, so I know the deal. The card ran, but it made little white dot looking thingies.
