I was cleanin up my room today and i came across my old EVGA Nvidia Geforce 8500GT 256MB (Turbo Cached 512MB) PCI-E Videocard...I got curious as to what i could overclock it too...I checked around some forums read that people were overclocking their 8500's to a ridiculous and very unstable amount...So far with Riva Tuner...Ive got this...

Original Specs...

GPU Core 459MHz
GPU Shader Core 918MHz
Memory Clock 400MHz

Overclocked Specs...

GPU Core 630MHz
GPU Shader Core 1260MHz
Memory Clock 510MHz

Updated #1 Overclocked Specs...

GPU Core 650MHz
GPU Shader Core 1300MHz
Memory Clock 510MHz ( So far anything above 530 presented artifacts )

So far these are completey stable specs...Ive been running ATI Tool's Artifact's Scanner for 11mins now and 0 Artifacts (If you get artifacts after overclocking it means its unstable and need to tone it down)...I'm gonna try to overclock it a little more will post with update

Very very nice! What are your load temps? Without an aftermarket cooler, I'd imagine that thing going up in flames...

Thats quite a respectable overclock for an old 8500gt. Careful not to melt the cooling fan though like my friend did to his 6600gt LOL!

Here's my results for my EVGA 8500GT V-Modded

I saw your post where you had found an Evga 8500GT layin around and then tried overclocking it with nice results well i actually have results for my old 8500GT also benchmarked it with 3DMark 03 and have a compare link for it i had actually V-Modded the card to get extra voltage to oc it alot better and have it be able to benchmark stably and i had great success with it i was able to pump out GPU/700Mhz--Memory/492Mhz and Shader/1450Mhz!!!! Here's a compare link--> http://service.futuremark.com/compare?2k3=6066507 And i used the stock cooling that was already on the card no aftermarket cooling what so ever!!! Im gonna be putting it back in to see if i can go even higher because i now have a way better rig then what i was using before so we will see what happens!!

The driver i used was FM Approved by Futuremark it was the Omega Drivers there great for Overclocking i used RivaTuner to Overclock it and the NV Strap thats built into RivaTuner to do some Hardware Mask Enabling!!!

200 MHz home overclock is just SICK! Manufacturers make OC models of cards just 25 MHz higer on core than default and call it OC version and want to rip off a lot of cash for that...

Ok bout time to do some overclocking and benchmarking

Ok so i have just took out my XFX HD5770 XXX card and took it apart i put the XFX HD 5770 Heatsink onto one of my old EVGA 8500GT 256mb cards and that thing works like a charm compared to the stock crap heatsink+fan EVGA provides. So now im gonna see how high i can clock it this time around and benchmark it. Oh and i read the EVGA box for my 8500GT card and it says right on it Extreme HD Gaming ahahahhahahaha what a load of BS seriously like you can do Extreme HD Gaming with this P.O.S. that only has 256mb ram ddr2 on it and the Bandwidth is only 12Gb/s hahaahah Thats just wrong how they false advertise that like [email protected] I will be posting results sometime today!!! :comp: :fight:
