Interesting.

Differences from X800:
X800 Pro memory clock
Apparently claimed to be an X800 Pro

Differences from X800 Pro:
110nm R430 GPU like the X800 and X800XL
X800 GPU clock speed (400 vs 475MHz)

You could probably just "over"clock the GPU to 475MHz and call it a day if you wanted. It seems unlikely we'd get to the bottom of why your card is like this.
(My guess: Palit got some lower-binned X800 GPUs to sell as x800 Pro cards and figured nobody would notice or care. It's hardly a big difference. That or they ran out of R420 dies and swapped in R430s for some cards and switched to a lower GPU clock.)

Thanks I think you're right. I did a bit of looking into the card and old emails. It is branded as an XpertVision and it seems it is simply a X800 non-pro with PRO speed memory. The photos of similar cards online all look like normal X800s.

I'm not concerned that it doesn't match 100% with the PRO. It ran great back in the day.

I recently picked up an X850 XT and it isn't that much faster (although I was testing on a P4 2.8 so CPU is probably a bottleneck).

You can't. R430 usually can be overclocked only to 450.

On many of those pros you can flash them to xt unlocking the 4 pipes

Try Atitool, https://www.techpowerup.com/atitool/ fast and easy, and lets see where it gets, don't forget to improve the cooling.

Depends on luck, I managed to run my R430 at 540 MHz, no mods or anything. https://hwbot.org/submission/2566166_havli_3d … ddr1_1514_marks

Btw - it is werid to see R430 on AGP card. There must be the Rialto bridge... and therefore more complex PCB. As far as I know R430 is native pci-e GPU.

Thanks guys. The cooling is really noisy on this card and I'm not sure why. So I'm not going to do any overclocking at this stage.

It runs like 50% fan usage all the time.

I have an X850 XT which I assumed would be way worse (due to higher clock speed and larger 130nm process) but it is actually much much better. The fan is normally running at 14% and is super quiet! It is a dual slot cooler so I suppose that helps.

I thought maybe thermal paste and I haven't replaced since 2005 but both GPUs run at 55-60c to very similar.

The cooler must just suck!

Here is the card. It even says just X800 which I missed before.

Ok, I've bought two X800GTO VIVO on R430 chip, but with intact X800XT/X850XT VRM and both can be oveclocked over 500Mhz. So looks like majority of R430 cards were just heavily undervolted. Same probably applies to AGP cards, if VRM looks sufficient enough and voltage is high.

Or all utilities just confuse R480 with R430, which commonly was used on GTO cards.

I can tell from experience, that these X850 cards tend to run rather hot, especially the higher clocked versions and die easily.
And if you happen to have one of the AGP cards with a native PCIe chip and the Rialto bridge (very often visible with a rubber-like frame around it), just make sure to cool that bridge!

So one card reached stable 600Mhz with R430 core, which is more or less identical to decent R480 OC numbers.
