Anyone have a 4850 x2?

Hey Guys I posted a problem i was having with windows vista x64 + my 9800gtx and decided it was time to upgrade anyways. Since i was getting a little tired of nvidias drivers i decided to pick up a saphire 4850x2 from the egg.

I have seen great things from the card in reviews and was wondering if anyone here had one and could tell me how it performs. Thanks!

i have and this happend 2 me

hi alll i am having this problem with my new rig



any game in example crashes when i start it fullscreen

i RMA'd the card for that and they where telling it was working well

i reinstalled vista sp1 32bit and xp 32bit + flash bios from mobo

removed 1 stick of ram took that out and placed in another one still thesame problem

then i just placed them back in and kept trying 2 uninstall drivers and reinstalling them with absolute 0 results

and all other games usuallly freeze and pc just restarts


1 time a managed it intoo GTA 4 and this happend http://kooola.ath.cx:1337/Crap/N95_558.jpg



when i run all games below in windowed mode there is absolute no crash @ all

only thing i notice then is that the card's second gpu is using 2-4% resources

and first 100% and the card's clock speed stays 507/500 while it is 750/900

i am about 2 give the card back and step over 2 Nvidia but i wanne give it another shot
and posting this around in forums hoping i find a sollution for my problem somewhere

its e8500 3.16ghz not oc
4gb OCZ 1066mhz
Asus p5q motherboard
Sapphire HD4870x2
600watt psu (olso had a 850watt while ago with same problem)

I own a 4850 x2.

-It worked fine when I used the 8.12 drivers, but the new 9.4 drivers screwed things up for me for some games. Since upgrading, I get massive distortion in some games (crysis, DiRT), none in others, and some minor distortions in GTA IV. Maybe the 9.5 drivers will help -- sure hope so.
When I bought it January, many reported problems with the drivers, but I didn't have any problems w/ the Sapphire drivers (ATI didn't start supporting this card until recently.)

-Koool - If the 2nd GPU isn't registering GPU activity when it should be, it means that you don't have crossfire enabled or the game you're playing doesn't support crossfire (which many don't.) I thought I had the same problem, but then checked it whilst playing Crysis and it was working fine.

-I get a lot of screen tearing and need to run Vsync on most any program (it's powerful enough to run Vsync w/o any noticeable drop in performance.) Not sure if this is a problem caused by the video card, however.

-I have a 750W Corsair PSU, and to my knowledge I have had no problems in relation to power.

-Positive: Overclocks well, runs pretty cool (usually in the 40's idle, 50s under load.)




If I had to do it over again, I would have just got a single card. The 4850 x2 will outperform the 4870 in games that support crossfire, but all in all, the 4850 isn't worth the extra cost. The new GTX 275 is about the same price as the 4850 X2, and if I were building a new system today, that'd probably be the card I'd go with.

Random question:

Where is GPU1 located on the 4850x2? Is it under the fan that's near or far from the DVI port?
