8800GT overclock help.

Have you soft volt-modded the card yet?

I don't think COD4 is going to stress the 8800GT to the limits though. My 7900GTX could max that game out, so an 8800GT will do it easy. Crysis GPU bench will stress it to the max.

Mine's running 702/1750/2000 stable on the GPU test in crysis. I've programmed the fan in rivatuner to hit 100% duty@65c. It does this within 30seconds of any game starting. It never goes over 70c. It is noisy at that speed, but i wear headphones, or play it so loud i cant hear the fan because lets face it, crysis NEEDS to be played LOUD! Those grenades sound awesome and scare the **** outta me lol

My 24 hour Orothis CPU overclock doesnt seem to be stable anymore according to Crysis and i'm getting no where near the gains I originally thought I had from ATI Tool regarding GFX overclocks.

Unless someone else can say that they ve had no problems with the ATI tool, i wouldnt use it. I did the same as you. got a nice OC using the ati tool, but the screen just went crazy 3 secs into the crysis benchmark.

so, just stick with crysis. :) http://downloads.guru3d.com/download.php?det=1791 if you didnt see the update to my previous post.

and how come your cpu is unstable? are you sure its not you GT?
 
Mines likes 702/1728/1998 well enough! :D

Scared to try higher!

Have the fan fixed at 60% now due to folding, seems to be inline with the noise the case fans already make... it hits just shy of 80oC :)

I'm preety sure its my CPU as computer just restarted when normally well everytime so far if I push my GPU it shows artifacts first then just stops with blurred bits all over the screen.

I have soft voltmodded my card, temps never above 60C on my VF900 so very safe could even hard voltmod it I reckon as I have Zalman heatsinks on the mosfets.

Did a quick try, passed 23 loops on 730 core, when i'm back from work i'll figure out the memory first, then the core then the shader. After all that and I get my new case next month i'll sort out my final CPU and ram overclock. Running the lot in a coolermaster wavemaster which is not ideal.

COD4 barely stresses this card I think, I was playing it the other day when I thought 1040 on the ram was stable and it never picked up anything, core was at 730 aswell without the voltmod, crysis fined my core to be no good at 710 without the voltmod, not sure the top core in crysis after the software voltmod.
 
What settings do you all use to play Crysis for best performance/looks ratio? I'm on a 1680 X 1050 monitor at the moment. For the benchmark I use full details 16XQADASS whatever it is, but that hovers from 23-30 fps which isn't playable for me
 
I play Crysis in DX9 using the Natural Mod and it looks damn good and runs around 30-50 fps for me for the most part @ 1080p. Not got to the (in)famous snow levels though yet. (lolz)
 
Right found my max core and mem that runs stable after 99 loops of the Crysis benchmark.

Core: 745
Mem: 980

So i'll run both at 740/975 for extra stability, now to find the max shader!
 
I dont think 99 loops is really necessary :D unless you dont mind waiting. since any of my unstable over clocks would crash Crysis after the first few seconds.
but to each his own ;)

Your CPU ok now?

nice to see you had some success with the soft modding. :) thats a nice core OC. Your shaders should easily got to 1750-1800 or more.

As for crysis, ive only got a 19" so 1400x900, but i wouldnt be using any form of AA. But using AA for the benchmark/stability test is probably not a bad idea.
I think i have everything on high, except for Game Effects, Postprocessing, and Particles Quality to medium. Makes for much smoother, quicker gameplay comepared to when i 1st played through it.

I know it maybe a bit extreme but i've had clocks crash around 60 loops before, i'm not one of these people who test it a bit and think yeah thats ok I like to know its exactly stable 100% all of the time lol, takes a lot of time but I just leave it on when I goto the gym/work/sleep etc.

I'm trying to find the shader at the moment but its quite alarming as i've done 3 loops adding 50 each time and i'm upto 1950 and it's not found anything yet - not sure if its working or it is, will have to push it some more.

I'm going to leave my CPU and RAM for now as my case is a joke and even at 3.4ghz the temps were too high, i'll wait until next week when I have my Antec 900.
 
well you could do your 3 loops with stock shaders and then put it up to 1950, do the same and check if the fps has gone up. cause it should... quite a lot :D 1950 is very impressive :D hope it turns out stable for you!

*edit. looks like you have a nice GT ;)

it makes me want to try soft modding, but I only have the stock cooler, so not too sure about it really. for temps and fanspeed/noise reasons.

I wouldn't bother with stock - I wasn't even happy with the temps of the stock cooler with stock clocks, the VF900 does a brilliant job, temps around 60C max - thats after softmodding in my crap case so leaves like 30C of safety room more than enough. I've put big Zalmans on the mosfets though as that always worries me, they're slightly bigger and fatter than the ones you get to put on the VRam.

EDIT: I'll take a pic sometime to show you what I mean.
 
Right, think I found my max shader overclock but i've only been able todo 40 loops due to time constraints, will have to leave it on tonight when back from work to see if it truly is the limit, 1915, thats quite high i'm very happy. If that's the limit i'll run it at 1910 for a bit of safety.
