Solved ATI Radeon X800 GTO crashing under load

January 28, 2015 at 13:32:24
Specs: Windows XP SP3, AMD Athlon 64 3200+, 1Gb DDR400
I recently grabbed a Sapphire Radeon X800 GTO card from a friends for only $5. I popped it into this old computer planning to run some older games that I previously got lousy FPS on. Although the system is single-core and is probably underpowered for the GPU, it's one heck of a lot better than the integrated chipset that's not worth the silicon inside it.

However, whenever the GPU is loaded (OCCT:GPU, Minecraft, etc) within about a minute it crashes. I'm sceptical of the computer's PSU (rated at 350w only) but the PC is only pulling a max of 140w from the wall at any given time. Under normal and light usage the system works fine. I rearranged the Molex connectors so the GPU has it's own set of wires while the HDD and CD drives run on a different set. There is no FSB overclock applied to the system. It is currently running Catalyst drivers ver. 10.2 from http://www.sapphiretech.com/present... . As far as I can tell all the caps look OK on it, and heat isn't an issue as the heatsink itself barely gets above lukewarm to the touch.

I have a Nvidia MX420 that I was using before, and it works perfectly. I don't have any other known working PSU's to swap with, and my Pentium 4 is out of commision while I wait for a new HD. Thoughts?

EDIT: I can hear a high-pitched whine from the GPU whenever the screen is updated, i.e a new frame is updated or I scroll up-down on a website. Somehow I feel that's not a good thing. I should also note that OCCT doesn't crash it now, but OpenGL programs do.

What is the brand & model of the comp?

✔ Best Answer
Terminology is important. GPU = Graphics Processing Unit. The GPU used on the X800 AGP is either the ATI R420, R430, or R480. It only supports Pixel Shader 2.0b so you may encounter problems with some "newer" games (2005 & up) but it will depend on the game. Can't beat it for $5 though.

A 350W PSU should be plenty for that card but it has to be a good one that's spec'd out appropriately. The AGP slot pulls the majority of it's power from the +3.3v & +5v rails & can supply a max of 48W. Some X800's required an aux power plug, others did not. If the noise you're hearing isn't coming from the fan, it might be coming from a capacitor or it could be coil whine.

Try uninstalling the Sapphire drivers & Cat Control Center, then install just the WDM Integrated driver:

Thanks for the replies.

GPU-z reports the GPU as an R430.
The PSU's nameplate is 20A 3.3V, 30A 5V and 15A 12V. As I said before, I have a dedicated Molex connector plugged into the card. Like I said, I'm suspicious of the PSU. It's branded as an "ISO-400". The Pc itself has no brand name, pretty sure it was a custom build.

After running Furmark (at a whopping 6fps) about half an hour, the temps reported by GPU-Z peak at 59.9C, sticking around at about 58C. No crashes amazingly. It also reports a GPU-BIOS verson of 009.009.001.004. Not that I think that matters.

As for coil whine I guess I'l just ignore it.

"The Pc itself has no brand name, pretty sure it was a custom build"

Ok, here is another tool.

I think 105C is max safe temp for the R430 so you should be OK at 60C under load. The PSU is apparently an older one with high amps on the +3.3v & +5v rather than the +12v. That's good for the AGP card but 15A on the +12v rail is on the low side. Which CPU? A64 3200+?

Specs exactly as listed on OP, including CPU.

I rolled back to the 9.xx version of Catalyst and it seems to be much more stable. We'll see in the morning, when I'll do some more burn-in.

Try as I suggested in response #2. Install just the 10.2 WDM Integrated driver. Do NOT install the Catalyst Software.
