    Fallout 3 Crossfire Problem 4850

    I've had the exact same issue with my 4850s in Vista x64 running the latest FC2 hotfix drivers......I'm running 1920x1080 with everything maxed (4X AA) and I get a solid 60FPS. After a little while I'll drop to 30-45.......I have to actually restart the game to get it back (well I haven't tried...

    The 4800 series Driver, OCing, Cooling and Tweaking Thread

    Well I've finally determined my max 24/7 stable OC.....stable in ATI Tool, Crysis, Clear Sky, etc. It's 735/1100 with 1.158V VGPU. I can bench 750/1150 and play Valve games, COD4, and other less demanding games, but I get driver resets in more demanding games. I'm going to try testing...

    The 4800 series Driver, OCing, Cooling and Tweaking Thread

    Well I installed Crysis again and played it for a few minutes at very high just to see how it ran and I got a driver reset about 5 minutes into the game......wondering if that's from unstable memory or GPU...I haven't put my sinks on a few memory chips yet (water block is in the way from...

    ati for video and nvidia for physx?

    Well considering that physics accelerated games are virtually non-existent it wouldn't be worth the hassle....however it may benefit you if you have a weak CPU.

    The 4800 series Driver, OCing, Cooling and Tweaking Thread

    Are you using an infrared thermometer or something? Well I have copper RAMsinks on mine with a 120mm fan sitting in front of my cards.

    The 4800 series Driver, OCing, Cooling and Tweaking Thread

    I'm actually going to do the VR mod, but I'm still not sure why I only get 1.17V in 3d mode when I flashed 1.21V....even 1.3V. I just edited my BIOS to have all voltages 1.3V and it's still 1.17 on both cards. :banghead:

    The 4800 series Driver, OCing, Cooling and Tweaking Thread

    Ok I've OCed my 4850s using BIOS flashing to 750/1150 and it's completely 24/7 stable. Mine are on water too. I finally got around to checking actual voltages with a DMM and found that I get 1.05 (probably 1.046, only 3 sig figs) and 1.17V at load..............however I flashed the BIOS to...

    ATI 4850 Overclock Results

    Well I'm going to test for higher memory clocks soon....I'm stable at 1125 so far....I ran vantage last night at 1200 and it was stable, but the score was lower..........I may have forgot to turn off my forced 16X AF though. Has anyone found an app to monitor the vGPU yet?

    ATI 4850 Overclock Results

    Well looks like I'm stable at 750/1125 @ 1.20V. I tried 775 and it was a no go. When I get my RAMsinks on Monday I'll try for higher memory clocks.

    4850 CF 8.6 hotfix Vantage distortion

    Yea I have Enzotech copper RAMsinks on the VRMs. I only had a few, and the VRMs get hotter than the memory......I have more sinks arriving Monday. The RAM seems to be doing fine naked.... Also the 8.6 hotfix is here

    4850 CF 8.6 hotfix Vantage distortion

    Well nevermind....I fixed it. Apparently a reboot is required if you disabled Crossfire, then enable it before running Vantage. LOL

    4850 CF 8.6 hotfix Vantage distortion

    Ok really strange problem here.......here is a quote copy/pasted from another forum. Anyone experienced distortion in vantage in the first test? Also when I get to my desktop Dreamscene is all wigged out, looking like a corrupted movie file download.....blockly with scattered textures, then it...

    ATI 4850 Overclock Results

    Well I have the cards installed, but I haven't benched them yet or anything...I just installed them and installed the drivers after removing my 2900XTs along with the water blocks and all the RAMsinks..... Tonight I'll test them for air cooled temps, then install the waterblocks and start...

    ATI 4850 Overclock Results

    I would advise against flashing in Windows.....use ATIFLash....much smaller chance of a bad flash. ATIflash can run on a small flash drive or CD.

    ATI 4850 Overclock Results

    Well I have two 4850s arriving between Mon-Wed and I'll have them on water.....so we'll see :D Anyone get over 900 MHz stable yet? What sort of (over)voltage are you guys running on these? How about memory OCing? I have some good Swiftech BGA RAMsinks that should allow for decent memory...

    PCIE Freq. in BIOS?

    It helps with stability if you're overclocking both of your graphics cards....if not then don't worry about it....you'll screw up your SATA drives or RAID array. I keep my at 113.

    ATI Catalyst 8.3, Hybrid CrossFire and CrossFireX Announced

    I take it back....I got AA working with Frontlines by changing the FFoW.exe to Oblivion.exe. BTW these drivers do not suck.....they own. Crysis DX10 performance is INSANELY faster.

    ATI Catalyst 8.3, Hybrid CrossFire and CrossFireX Announced

    It's still not posted....my guess is that it won't be posted on AMD's site until 12PM Eastern. That's typically when they release/announce things.
