Little OC'ing Problem (Video Card)

[JdPower]

Hey guys,

I just recently got my Sapphire X800GTO AGP card and I got it to 16 pipes. Well I wanted to go further and OC it. My first attempt was successful (450 / 400 [mem/core]). I launched CSS and started playing and it was awesome! Yet, I my mind wonder and wanted to do more OC'ing. So I opened ATItools and hit the "Find max mem" it shot up to about 475 and then slightly went down so I stopped it. Next I hit the "Find max core" and I watched the Lil 3D fuzzy box And all of the sudden the box just went lines of yellow. My understanding is that those are "Artifacts." So before it started that it was fine at 468 so I put it there! After that about 2 mins later my whole Computer just froze!! So I had to hit the restart button. Everything loaded up fine no errors or anything. I immediately went into ATI tools and turned each down to 450/450 and then waited for anything. Nothing happend for 5 mins. I then loaded CSS and started to play for about 10 - 15 mins and it just FROZE again! After that happend I decided that enough of that and loaded Trixx and turned on "Silent" setting. I then went to bed and put the computer to "Hybernate" and in the morning I did not wake up to a frozen screen and everything seemed fine!

So am I doing something wrong here? I havent had exp. with OC'ing Vid Cards just some exp. with OC'ing my AMD proccessor! I havent really explored ATItools so... Any suggested are greatly appreciated! Thanks

seems right
which driver?
so how long do you have ati tool running before using the clocks?

All drivers are up to date. Before I installed the Video card I reformatted so its a clean slate with ALL new drivers! And I have the ATI tool running (the first time) 2-5mins (the 2nd time) 10-15mins. Seems like I could OC it more tho... ?

I think I figured it out. I have ATI tool version 0.25 beta, and I honestly dont think my system liked that version. The box was laggy and seemed to run sluggish! So i uninstalled and installed beta 0.24 version and it seems like it works perfect. OC it to 440/569 and runs good at 40/39 at idle and at load 49. CSS runs smooth and clean @ max 100fps low 75fps.

its best to find your max core and memory manually.. raise the slider bar and set the speed.. do it one at a time.. watch the furry dice.. when u see artifacts knock it back a bit..

the memory will nearly always show artifacts well before crashing.. the core might just crash.. either way u know the limit of each for real..

run a few 3Dmarks to stability test then play some games.. if i all works its okay.. if not u have to slow thing down till it does.. run at least %5 slower than your actual artifact or crash points..

Thanks trog...

I played CSS on the 440/569 for some hrs and stability is good. No crash no exiting of the game. I did a stress test that they have (not like the 3dmark, but its something) and came back with an avrg. 85fps. You think I could bump it up some? I have 100% fan on and its idles at 40-45, at load the highest i've seen is 58. I have a PCI fan card w/ 2 fans (vantec) that I can plug in and I am sure it will help.

I adjusted the core clock first but I was doing it with the "Find Max Core" button. I will do manully. How high do you think I could go? same with Mem.

set either the memory or core at lower than known safe speeds.. slowly raise the other one in small steps at a time.. do it while running the dice it heats up your card and is a basic test.. u will find a point at which artifacts appear or the card simple crashes.. note that point.. lower the thing u have been testing down to that known safe speed or lower.. then do the same thing with then other part..

u find the max point for each.. core and memory.. knock %5 of of both max points and try em both together.. it takes a few days of real gaming usage before u find the nice sweet spot between max speed and stable running..

the gain from pushing to close to the edge is okay for benching.. but for normal gaming i always run about 7% below the instability points..

u wont damage anything.. just do it slowly and carefully..
