ASRock939 AGP Rate?

[CFster]

I have a 6600GT on a ASRock 939Dual.

In display properties it's reporting 8X AGP for the BIOS, Hardware and Optimal, but it's showing 2X for OS. I'm getting some pretty lousy 3DMark05 and Aquamark scores too.

I did a fresh install of XP and immediately installed the ULi AGP driver, not the ASRock version - then the nVidia graphics driver.

It's set to 8X in the BIOS, along with Aperature set to 128MB. I've tried changing fast writes with no success too.

I've tried both the 1.2 and 1.3 BIOS.

What am I doing wrong?

what exactly are your scores for for benchmarks and what are the other components in your system

when you were installing the drivers, did u reboot between ULI intergrated and nvidia drivers???

also try using 78.01.

I just updated my ULI AGP driver to 3.0 and am having the same damn problem and i is absolutely killin me.. my frames are down in q4 and it is unplayable.. but i CANNOT get it to recognize 8x AGP

everything was fine before this.. I have uninstalled it, reinstalled and then reinstalled my card driversand the same thing.. this is BS.. anyone got any ideas?

oh.. my motherboard is a gigabyte ga-k8u-939

and im probably gonna send it back and get something else as i have had nothing but problems with this board

I had the same problem - not seeing my AGP as AGP, here is what I did:

1. Fresh OS install
2. Installed AsRock AGP drivers
3. Installed AMD X2 driver
4. Install vid driver. I have a 6800GT so I am using 81.85 drivers

everything now works like a charm.

I'm having a very similar problem....


1. I couldnt select anything other than PCI mode in the ATi CCC, when I tried 4x or 8x mode it booted up on AGP 0x again. I uninstalled all the drivers (ATi + the AGP 3.0 driver for the Motherboard) and let windows re-install them on reboot. 8x AGP then worked in the ATi CCC.... This may help you.

2. Now 8x was working I benchmarked and was happy to see nice increases - until it crashed. Every game I play (HL2/COD2/BF2/FarCry) crashes at a random time anywhere from 1-2 mins up to 10 minutes after starting.

With AGP 0x is wasnt crashing at all. It still crashes with default XP drivers for the card.
Edit: When I say crash, the computer freezes the picture and loops the sound for a couple seconds - then it requires a reboot.

Is there a chance my PSU is overloaded (or very close to being so) when I run a game because its in AGP mode? The only change before it became unstable was to change into AGP mode (though this may be a pure driver issue?).

Hardware concerned:
ASRock 939 mobo
Athlon X2 4200+
64-bit Windows XP

520Watt Vantec Stealth PSU (BIOS records 3.4v on +3.3 and 11.95v on 12v) (PSU runs 3 HDDs, 4 Optical Drives, 2 Delta fans, 6 other case fans, the new mobo and cpu, and my X800XTPE)

A couple of suggestions:
- Some report problems with AGP aperture value greater than 128.
- Some - myself included - have to run with 2T command rate for complete stability.

In my case, I have to run 2T command rate at any memory clock speed greater than 133MHz. It'll run Prime95 for hours at 1T, but will crash with page-fault error whenever a significant memory page-write is encountered.

Best test for 1T/2T problem is Memtest86 Test#8. I can't pass Memtest86 Test#8 unless memory set to 2T command rate.

Hope this helps!
