I recently bought three Sapphire HD3850 AGP video cards to upgrade three aging systems. The system configurations before and after the upgrade are:
3800X2 (939)
K8N Neo2 Platinum (NForce3 250)
2GB RAM
HD3850 (AGP) (was X800 AIW)
Antec Basiq 500W
XP2700 (462)
K7N2-Delta (was 8K3A+)
2GB RAM (was 512K)
HD3850 (AGP) (was Radeon 7000)
Coolmax CT-450
XP2800 (462)
NF7-S2G
2GB RAM
HD3850 (AGP) (was X800 AIW)
Antec Earthwatts 500W
The system that I had the least difficulty upgrading was the 3800X2 system. After uninstalling the old ATI software I was getting a message that I had to install the drivers from the 3850 CD from an Administrator account, when I was already in an account with administrative privileges. I ended up booting into the Administrator account in safe mode and installing the drivers through device manager. I?ve since updated the drivers to the Catalyst 8.10 AGP Hotfix drivers with no problems.
Here are the results from some tests that I ran:
3800X2 with X800 AIW (AGP)
3DMark2000 - 16830
3DMark2001 - 21038
3DMark03 - 11888
3DMark05 - 6021
3DMark06 - 2135
3800X2 with 3850 (AGP)
3DMark2000 - 16575
3DMark2001 - 22753
3DMark03 - 26735
3DMark05 - 10435
3DMark06 ? 6883
The socket A systems were a major pain to upgrade. Most of the discovery of the limitations of the socket A systems were done on the 2700 system. Four different power supplies were used, one was actually on the ATI approved list (which is now in my current system). Two different motherboards were tried, the other board was an 8RDA3+. The problems were not limited to the HD3850 upgrade but also showed up when the X800 AIW was used. Details on the testing process can be found here in the CPU forums. The only problem that I had was that the systems would blue screen at specific tests in 3DMark2001SE, 3DMark03, 3DMark05, and 3DMark06. The tests would always blue screen at the same point within the test.
After searching around I found two suggestions that worked:
1. Run the Catalyst 7.12 drivers with the file ati3duag.dll pulled from the Catalyst 7.7 drivers and inserted into the System32 folder.
2. Down-clock the CPU FSB.
I saw that most people were reducing the FSB from 166 MHz to 133 MHz, the resulting test results:
XP2700+ @ XP2100+ (1.733 GHz) speed with X800 AIW
3DMark2000 - 10112
3DMark2001 - 12797
3DMark03 - 9804
3DMark05 - 4912
3DMark06 - 1865
XP2700+ @ XP2100+ speed with HD3850
3DMark2000 - 10623
3DMark2001 - 14302
3DMark03 - 21065
3DMark05 - 5985
3DMark06 - 3830
Through experimentation I found that the limit that either the 2700 or 2800 CPU would run at (and not fail the 3DMark tests) was 1.9 GHz. I ended up settling on 1.872 GHz (144 X 13) on the 2700 and 1.875 GHz (150 X 12.5) on the 2800. The test results were:
XP2700+ @ 1.872 with HD3850
3DMark2000 - 11338
3DMark2001 - 15081
3DMark03 - 21848
3DMark05 - 6351
3DMark06 - 4034
EDIT: The following test shows that the 3850 is limited by the CPU.
XP2700+ @ 1.872 with HD3850 OD'd (709 core / 939 memory)
3DMark2000 - 11281

3DMark03 - 22207
3DMark05 - 6309

3DMark2000 - 11601
3DMark2001 - 14070
3DMark03 - 10050
3DMark05 - 5301

3DMark05 - 6776

Test results for using modified Catalyst 7.12 drivers are as follows:
XP2800+ @ default (2.083GHz) modified Catalyst 7.12 with X800 AIW
3DMark2000 - 12308
3DMark2001 - 13890
3DMark03 - 5502
3DMark05 - 4451
3DMark06 - 1515
XP2800+ @ default (2.083GHz) modified Catalyst 7.12 with HD3850
3DMark2000 - 12569
3DMark2001 - 17447
3DMark03 - 21787
3DMark05 - 7373
3DMark06 - 4673
Since the goal of the socket A systems was stability first, then speed ? I settled on the down-clocked CPU FSB option. This way the system could take updated drivers which incorporated fixes. The socket A systems are going to nephews, one of those being over 1200 miles away.
I took one of the X800 AIW cards and dropped it into another 2700 system that I have. The 2700 system is on an 8K3A+ system and is prime stable at default speeds. This system has the same symptoms as the nforce2 based systems.

EDIT: During my research I've found mostly AMD socket A systems to have problems. If any P4 systems had problems they were usually based on Nvidia or VIA chipsets.
