I have tried the softjumps, but since the CPU is HWblocked against overclocking, I can't change the CPU speed. The only thing I can do is to set the RAM speed to 124MHz. The stupid thing is that the next speedstep is 143MHz, and my RAM doesn't handle that

My videocard is a GeForce256 DDR-RAM (Asus V6800). If I try to activate the Fast Write (powerstrip) the machine just hangs, and I have to do a hard reboot. And it says u can use AGP 4x, but when I try to mark it, nothing happens (also powerstrip)
When I built my system, I just followed these points (from NTcompatible) and have had no problems with it.
Received the follow messages:
1)There are numerous problems with this
motherboard and Nvidia GeForce cards. Win2K will refuse to boot, giving
bluescreens, etc.
I managed to get mine operating, but it's
still somewhat flaky.
- Display DIMM interleaving in the BIOS
- Run the Nvidia 5.13 driver
2) I had all the same problems when I
started, but after I went through some newsgroups, I found out that by
disabling the DRAMM Interleave (I think it is set to "auto" by
default) it actually works pretty well.
3) Works well but need to change AGP and PCI drivers
otherwise you cannot install latest NVIDIA drivers. You need to change them by
the AMD751's one. Open the directory Patch/W2000 of the CD and install the patch.
Then manually install :
AMD751 Processor to AGP Controller
AMD751 Processor to PCI bridge
Let me know how your building goes, and also if u find anything about the AGP 4x.
