So you think you're a vid card guru? what do you know about APG bios settings? See what Diamond Says the bios settings should be for the Viper V770 Ultra.

I know that this card is not the most current, but I finally got a mobo that will run at 4x and I'm having trouble getting it to work at that speed. It works fine at 2x.

Please look over the bios settings that were recommended and tell me if you've experienced anything different than what they told me.

"...You should also check these BIOS settings:

[BIOS SETTINGS: PCI/AGP]
- IRQ assignment [enable]
- Boot with PnP O/S [enable]
- Pallet snooping [disable]
- PCI bursting [disable]
- PCI latency timer [128]
- Peer concurrency [disable]
- Video BIOS shadowing [disable]
- Video BIOS cacheable [disable]
- Video RAM cacheable [disable]
- Byte-Merge [Disable]
- Decouple Refresh [disable]
- Hidden Refresh [disable]
- USWC options ["Uncache Speculative Write Combining" is similar to Video
BIOS Shadowing/caching]

[BIOS SETTINGS: AGP- specific]
- USB [enabled]
- PCI 2.1 compliance [enable- also may assign IRQ to VGA]
- Passive release/refresh [enabled]
- Delayed transactions [enabled - may also enable PCI 2.1 compliance]
- VGA BIOS Sequence [AGP-PCI, PCI-AGP, PCI]
- AGP/Graphics aperture size [Lowest possible setting]
- Write Cache Pipeline [disable]
- Read Around Write [disable]
- Primary Frame Buffer [disable]
- VGA Frame Buffer [disable]
- AGP Bus Turbo Mode [disable]
- AGP Transfer Mode [1x]
- AGP set to 2/3 instead of 1/1
- AGP Multi Trans Timer [disable]
- AGP Low Priority Timer [disable]
- AGP 2x [disable]
- AGP Turbo Mode [disable]

If the board has a soft CPU select, and there is a setting for the AGP
multiplier like 1/1 or 2/3, that needs to be set according to the front side
bus:

66 MHz FSB-- AGP speed =1/1 (66mhz)
100 MHz FSB-- AGP speed = 2/3 (66mhz"

Please let me know what you've experienced. For more details of the mobo that I'm working on you can check my thread under the motherboard topic. It's fairly new right now and should remain towards the top until I get some issues resolved.

Thanks, ALan

Sorry, The Viper V770 is an AGP card. Most of you will know that because that is the only flavor that the card came in.
