Serious issues with Gigabyte 3870.
Hi all. Im new here but back to topic. I received yesterday brand new Gigabyte HD3870 card from warranty which has GDDR4 memory.
This card also suffers for big powerplay issues. I carefully read all posts in this thread and tried the things and different bios`s and Catalyst 8.3 & 8.4 drivers. Powerplay issue is still there :(
My current rig is: Q6600 @ 3.6Ghz / Asus P5E / / 4GB 4-4-4-12 DDR2 800Mhz
With 3DMark06 i got only 12300 points. With my Club3D 2900XT i get 13500 points! How this is possible? Also i get with my 2900XT from Crysis benchmark avg. fps 35.5 while i got with this Gigabyte 3870 card avg. 28,46fps. What the heck? Should not 3870 be little bit faster than 2900 ..appearently not.
I even downloaded bios Gigabyte.HD3870.512.071123.bin and set fan to 40% speed and low3d gpu speed to 777MHz. It seems i still suffer for heavy powerplay issue or how it can be this is that much slower than my old and good 2900XT !?
By the way, you should guys use latest Radeon bios editor 110 instead of other tools.

This tool is very pro. because you can set the fan speeds etc.
With my 2900XT i can play Crysis MP with about 35-45fps pretty stable. I tried today with this 3870 card and fps were because of above issue 25-35 wich maded my game unplayable with Very High cvars.
This means i will likely sell this 3870 and put my old and good 2900XT back. What is even more ridiculous is that how came fan speed with stock settings for this card was all of 4% which maded this card temperature 60-65C when it was idle! Also this powerplay bug make me soon change to Nvidia cards ..i still can´t find any official fix for this issue.
If somebody might have any idea how to fix this issue, please tell me thanks.
PS. I forgot to mention, im using WinXP with SP3, so powerplay is not only Vista related issue.
