My PC accepts only single-slot cards, that is why I was looking for this HD 4850, because I considered it to be a good replacement for the card I was using before - Sapphire Radeon x1950 Pro. I would see if you could find the original BIOS and flash it back to the 4850 as the only thing I could find by searching the BIOS version was this: If I recall correctly the RV770 was used in both the 48, only differing by the memory available and the clocks that the GPU was binned for.Īccording to your core and memory clocks and from the picture, it looks exactly like a 4850.īiggest thing to note here: The 4850 had 512MB of VRAM, the 4870 had 1GB and clocks look like those for the 4850.Īpparently, there are 1GB versions of the 4850 and it's reading them as GDDR3. If it's crashing, it's probably flaking out when it tries to use the extra 512MB of memory that isn't there. The device ID in GPU-Z is wrong and doesn't seem to match the 4870, 1002-9442 is for the 4850, not the 4870 from my googling.Īccording to the device ID, it looks like the the previous owner flashed a 4870 BIOS to the GPU. So I got desperate and, being 100% convinced that it is a driver problem, I decided to try another driver, and somehow I came across the one you see in the photo below: XP - Professional/Home&RenderOnServer=trueīut the same thing happened, both with Return to Castle Wolfenstein and with Call of Duty 1. Well, that was way too much for me, so I re-installed Windows (I use XP Professional SP2) and re-installed the game too, and then installed the driver from the AMD site: And what do you know? The fps got as low as 30 in some places, and instead of being constant, like it always was before, this time it was variable, always changing depending on how I was moving in the game. Then I played Return to Castle Wolfenstein - the 2001 game which never lagged and almost always kept my fps at 91 - the maximum fps this game allows. Here is what happened: last night I got an incredibly low framerate in Call of Duty 1 and United Offensive, about half of the fps I normally got with my previous card - Sapphire Radeon x1950 Pro. I decided to create another thread about my problem here, since I am now convinced that there are some problems with the drivers for the card.
