Odd GPUs from XFX maybe

post #1 of 7
Thread Starter 
Well I was wondering why I couldnt OC my new 4850 from xfx
http://www.newegg.com/Product/Produc...-482-_-Product
Then I started wondering if maybe I could OC my 4830 to be the same speeds BUT! something very interesting showed up.

Now we all know the 4830/4850/4870 all use the RV770 chipset right?
WELL the latest GPUz shows


What gets more interesting is that IT STILL Runs both gpus in CFX
Buuut when I searched up that GPU , it turns up as a Mobile processor
http://www.techpowerup.com/68008/ATI...he-Making.html Why in the world did XFX give out a bunk gpu and not the real deal? This might be why I cant overclock it for ****

Well that is rather interesting. What kind of results do you get in crossfire?

Maybe but theres too much of a coincidence (however you spell it) that the M98 is the mobile version of the RV770

GPUz gets it's info from the BIOS on the card.

Since XFX is probably using a custom bios, GPUz is confused, and read it as a M98.

Most likely since according to some people that the drivers on the disk allow overclocking and the official amd drivers dont.

Here's the results from DX9 Lost Planet 2 Benchmark TestA

4830: AVG=17.2 Run1:14.2 Run2:18.4 Run3:18.9
4850: AVG=35.4 Run1:34.5 Run2:37.5 Run3:34.7
CFX: AVG...oops Run1:41.9 Run2:35.8 Run3:49.4

Noted that in CFX that the 4850 only runs at 75% on run1, then 40-60% on 2 and 3 while the 4830 is running at 99% all the time

Settings: All Maxed at 1920x1080 8xMSAA
