XFX HD4850 1GB using mobility chip?

post #1 of 6
Thread Starter 
I picked this up last week @ http://www.newegg.com/Product/Product.aspx?Item=N82E16814150482

A reviewer claims this model uses the 4800 series mobility chip "M98". GPUZ shows it as an M98. gpuz.jpg

If this is the case, Is there a performance/reliability issue using this chip? instead of a regular 4850 desktop one? I cannot overclock it with the latest 11.2 drivers, but can with the old 10.xx on the install disks.

I bought that card as well. I could not pass up the offer...47 dollars after rebates biggrin.gif I installed the newest drivers and just overclock it with MSI afterburner. You could use that as an alternative instead of installing the old drivers.

I have noticed though that the past few days I canno't overclock the memory clock. I am able to get the core clock to 700mhz, but if I move the memory clock even 5mhz I get BSOD's....

yeah, i have the same card, and i see some troubles. under pci-e x8 runs normal speed clocks, and under x16 are more slow. confused.gif

yeah and gpu-z show buggy this card. no OpenCL and Directcompute. frown.gif

i changue the vendor under bios to gigabyte. and now work normal the clocks under x16 and set the 1.123v

because using 1.158v default 625 993 clocks

i recently purchased this card for $40 from newegg... was wondering if i should use the 10.xx catalyst drivers to allow overclocking, or if I should just download the latest drivers to be safe and not overclock all together? Also, in both cases would i download the desktop or mobile version of the drivers?

Thanks in advance for all your help.
