No AGP4x when overclocking CUSL2

[Knorp]

CONFIG:
Motherboard: Asus CUSL2 Rev 1.02
Bios: 1003 beta 2
Memory: PC100
CPU: P3-850 S370
Video: Creative Geforce 256 (SDR)
Drivers: Nvidia 6.26
OS: Win ME + Win 2000

COMPLAINT:
When running the system in standard mode, eg 100/100/33 (850Mhz), all AGP-modes are available, being 1x, 2x and 4x. Also Geforce is capable running 4x.
This has been detected by both WCPUID and Powerstrip.

However when overclocking anything above 105/105/35 (>892Mhz) a very annoying situation occurs, AGP-mode 4x is no longer there ! Only 1x and 2x remain. For a system capable of doing 120/120/40 (1020Mhz) i find it hard to buy that this AGP-mode 4x disappears by a whisker over standard clocking.

QUESTION:
Anybody else out there experiencing the same problem ?
Some hints or tips maybe ?

Thank you,
Knorp.

I heard that as soon as you hit 140 FBS, it switches to AGP2X all by itself. No idea if there's a fix.

how can I know my mobo's Revision no.? for me any BIOS other than 1001.a down grade my agp4x to 2x if I'm using FSB higher than 140 and I'm using the i815e drivers that came with the CD.

This drop down from AGP4x to AGP2x only occurs on BIOSes after 1001A.
