I recently got a PowerColor Radeon HD 2600xt 512mb AGP graphics card. It seems to be working fine, but when i look at my system information it reports it as a 256mb graphics card instead of a 512mb. Does anyone have any idea why this is happening? i have looked around for answers and the only one i could really find is that it might be my mother board not being able to suppose the full 512mb?

I don't buy that.

Download and run GPU-Z http://www.techpowerup.com/downloads/ . It will give specific info about your videocard.

i ran that program and it says 256 as well. i looked on the actual card and it has a tag that says 512 mb. idk what the deal is. think the card is marked wrong? or just says 512 because it is 256 ddr2?

Well, look at your memory type/speed on GPUZ. The only 256meg Powercolor 2600XT I found has GDDR4 memory at 1100/2200mhz. I didn't know DDR4 was even being used.

The 512meg card shows to have GDDR3 at 800mhz.

Sometimes cards are mislabeled, sometimes a memory controller takes a dump. You might be due a trade/refund if the card is a different one than you paid for. That being said, the 256 meg GDDR4 will be the faster card on most games unless you run out of memory.

Memory type is DDR2
Memory says 396mhz
i was thinking it might be mislabeled.
Its supposed to be 128bit and this program is telling me its only 64bit.
im guessing i should contact the place i bought it from and trade it in or get a refund.

If it is only 64-bit, and DDR2 memory, definitely trade it in even if it costs you some more money. You will have trouble playing newer games even on low settings with those specs. Try to get at least 128-bit and DDR3 memory. I don't think the 256mb instead of 512mb really makes a difference in your situation.

Are you positive it isn't a HD 2400PRO? That would fit all of the specs you have listed so far. If someone sold you that as an XT, by all means take action.

i bought it as the HD 2600xt. The box it came in was the HD 2600xt box. The system information says it is part of the 2600 series though.

Do you have the latest drivers installed from the ATI website? The ones on the cd are usually very outdated.

If so, I think the card may be a dud. How is the performance in games? Newer games probably won't play well on it at all, but most games from around 2005 (maybe 2006 too) should play well on medium-high settings.

Ditto. Update the drivers to 8.12 and run GPUZ again.

do you know where i could get this driver?
i cant seem to find it. I looked on the ATI website, but their 2600 series driver doesnt work. Keeps saying i dont have compatible hardware. I think it is for the PCIE version of the card only.

Time for an RMA. If you did get it from Newegg, it should be easy.
