Hello, I just overclocked my nVidia GeForce 8500GT...

Core Clock: 459MHz to 727MHz
Memory: 800MHz to 930MHz

What I would like to know is, how much heat can a GPU handle before overheating?

PC1:
- Asus M2V-MX SE Motherboard
- AMD Athlon 64 4200 X2 Dual Core CPU, 2.2GHz
- 1GB DDR667 Memory Module, DDR2
- nVidia GeForce 8500GT 512MB

PC2:
- Core2Duo Laptop/1GB DDR2

The Overheating alarm on nVidia Monitor is set to 127C default, is that to high? I just ran a benchmarking program after overclocking, and the GPU hit over 70C, is that to hot?

I don't know much about overclocking so any help would be great. Thanks in advance.

The 8500GT isn't a very good card to begin with...overclocking will help performance somewhat, but it can't make up for the fact that it only has 16 stream processors. I'm guessing that the card you have uses GDDR2 memory. The "better" versions uses GDDR3.

But for about the same price, you can get an 8600GT w/32 stream processors.

BTW, lil leo, "u need ram to clock ur card too" is a pretty "amatuer-ish" statement in itself. Please honor us with your extreme PC knowledge & elaborate.

It all depends on your exact video card. No two cards will perform exactly the same. If you are going to do a big overclock like that, you really need to introduce more cooling. It might run fine when you're word processing, but it'll skyrocket when you get into high-intensive games.
