View Full Version : Testing the stability of an overclocked geforce
Core: 1. 200 2. 245Mhz 3. 261
DDR: 1. 460 2. 539 3. 558
2. Ran this during the weekend without problems.
3. Testing this now.
I have seriously pumped my rigs with oversized fans. The GeForce card alone have a 80cfm 120mm Titan Aluminium fan pointed at it (BEAST!) (sucking air from a hole in the left side of the dragontower), with a titan 'System Doubler Blower' 21 cfm mounted right under the original fan. The result is that my GPU runs very cool according to ASUS SmartDoctor (lowered about 25c something).
Now, what I wanted to ask is, running cool is one thing, but does anyone know a good way to test stability on a GPU to be sure it works ok? It currently runs at 58c (it ran on 75c non overclocked before I put in the new fans) with 35c ddr.

Best way I've found to test GPU stability is to run loops of 3DMark 2001 (that program actually is good for something ;) ). Back in my GeForce3 days, I tested my overclocking sucess by loading up 3DM and setting a really high number of times for all tests to loop. I went out to class and came back about 4-5 hours later. If the tests were still running, I deemed it a success, if my system was locked, I had to throttle the core speed down a bit.
Thats what I did so far. Not for 4-5 hours, but once. But perhaps I should set it looping instead. :)

Yeah, I would set it to loop each test 20 times. Even when my core was overclocked too high, I typically could complete up to 5 3DM runs in a row before my machine hardlocked.
I ran it an hour stright, thats 10 times. It feels a bit 'choppy' thou. It staggers once each 2-3 seconds. Hm.
Im going to test it outthrough. Thanks for the tip about 3dmark. :)

This is the sign I use to throttle back. The card isn't failing dramatically at that clockspeed, but it is failing.
I used to use 3DMark also, running once was enough, as it would always freeze on the advanced pixel shader test if it was too high. My vanilla GF3 is OC to 240/560 for the last 2+ years. My card is in my sig, but this one did come with a BlueOrb cooler which helps, also took off the fan and cleaned it all and cleaned the chip and added some silver thermal paste ;)
Anyone tried a program called "Artifact Tester 2.0" ?
It's meant to look for image problems on an overclocked card.
Sorry, don't have a link.
But it came with the latest Omega 43.45 drivers.
I didn't like the drivers, but this utility seems quite nice.
It seems like 5.0 is available. Nifty little utility. Ill try it more when I get back home. :)
The first number is the stock number, the second is the overclocked.
Note that v8200 is underclocked by default compared to other cards, if you wonder why a GF3Ti500 is that low.
Core: 200 -> 265
DDR: 460 -> 589
Taken right after 1 round of 3dMark 2001
Chipset heat: 55c -> 63c
RAM heat: 36c -> 28c
3dMark 2001: 7881 -> 8944
Side note: Tested with desktop set to 1024x768.
Having desktop set to 1940x1440 gave me 7802 marks at stock speed.
