Alright guys and gals...It's been a while since I've been here. Hello to all of the old timers out there that remember a very different look in the forums and the "Other"!
I've run into an issue during an upgrade. Here's the system:
Athlon 64 X2 3800+
Asus A8R-MVP Rev 1.02G
Windows XP with SP3 and all high priority updates installed
2GB of G.Skill PC4000 (2x1GB)
Antec NeoHe 430W
Creative Audigy 2ZS
Samsung Spinpoint SP2004c
NEC DVD-RW
GPU: Sapphire X1800XT being upgraded to HiS HD 5770
Here's the basic timeline:
1. Prior to GPU upgrade all drivers for mobo and periphs were updated and flashed to most recent mobo BIOS.
2. Followed graphics card update procedure -> uninstalled old drivers, shut down PC, installed new card, booted machine, installed new drivers (ATI 10.3 came on install CD), rebooted.
3. After install was complete I noticed a performance degradation. Opened Task Manager and observed System Idle at 90-100%, but CPU usage averaging between 40-50%. Specifically, one of the two cores had nearly 100% usage and the other core had near 0% usage. No processes identified as eating the CPU cycles.
4. Googled the issue and found Process Explorer - great little program! Opened Process Explorer and discovered that Hardware interrupts were the cause of my high CPU usage.
5. Thought it might be drivers: uninstalled 10.3 drivers, rebooted, opened Process Explorer and found that hardware interrupts still present with no drivers installed. Installed ATI 10.7 drivers/Catalyst Control Center and then rebooted. Hardware interrupts still present with newest ATI drivers.
6. To verify that the source of the interrupts was the video card, I reinstalled the X1800XT. Hardware interrupts went away. Reinstalled HD 5770 - interrupts returned, therefore it is definitely the source.
7. Googled more and found that there was a possible cause from SATA trying to use PIO instead of DMA. Verified that DMA was selected for pri/sec SATA.
8. Banged head repeatedly on keyboard.
9. Logged onto THGC to ask...Has anyone seen this? Have a solution? Is this a known issue with a fix coming? Driver or hardware?
Any help would be greatly appreciated!
