Detonator infinite loop problem

[Tano]

Hi

I'm using WinXP with an Elsa Gladiac and i have a little problem. All versions of detonattor XP turn my sytem into BSOD with a message: display driver turn into an infinite loop

If i set my FSB back to 143 from 146 it works well.

Does anybody know how could i solve this problem? Somewhere i read a news that said there is a solution, but i forgot which website was that.

You didn't mention which board you're using, but if it uses the KT133x Host Bridge...you might want to give this patch a try. You could also use Wpcredit to manually change bits 5, 6, and 7 to 0 in register 55. Increasing the "AGP Driving Strength" value in the BIOS might also help to fix the infinite loop problem.

Quote from ViaHardware.com:

This patch detects the 0305, 3099, 3102, and 3112 (KT133x, KT266x, VT8662, and KLE133) *only*. On these chipsets, it will patch register 55 in the Northbridge, which will supposedly switch off a Memory Write Queue timer.

In the KT133A datasheet, register 55 is "reserved". But - yikes! - in the KT266, the documented MWQ register is register 95, not 55. Register 55 contains unrelated DDR timing adjustments and could actually be dangerous to program. For this reason, I do not recommend installing this driver on the KT266x chipsets until VIA examines this issue. For now, use WPCREDIT and set bits 5, 6, and 7 to zero in register 95 instead."
You can download the patch from here...

Sorry for my lack of information.:) I'm using a MSI K7T-Turbo mobo.
Unfortunately i can't set the AGP Driving STrenght in the bios, but i will try the patch you say.
Thanks a lot.:burn:

You can adjust the AGP Driving Strength value even though it's not an available option in the BIOS (MSI has obviously hidden it from the user). You can use Wpcredit to change the value of register B1, which is the AGP Driving Strength. As seen in the shot of Wpcredit below, register B1 is set to EA (it was DA previously).

Using a Decimal to Hexadecimal Conversion Table...

DA=218
EA=234

You can find this table at the following site...

...along with the correct *.PCR file for the KT133x Hostbridge.
