System:

Duron 800 (not overclocked)
Abit kt7A
Crucial PC133 CAS2 Ram
sblive
Fireball plus as 20.5gig
Fujitsu 6.5gig
Pioneer DVD 115 16x
Mitsumi CDRW 4x8x24

Just bought an ELSA Geforce 2 MX graphics card, and a simple job turned into a nightmare (sound familiar?).

I've installed the card but have some minor + major problems:

MAJOR

1) With the system at default speed and voltage, the stupid card refuses to work in 3D at AGP 4x with fast write support enabled.

Only when I reduce the settings to AGP 2x does the thing run games - WHY? I'm under the impression that this card supports AGP 4x and fast write. Please help!

2) I get some fantastic drivers with the card allowing overclocking and performance tweaking extreme - fantastic. Only these drivers install off the supplied CD with the card, and when I try and use updated detonator drivers off ELSAs official site, I lose all the fantastic tweaking software no matter which route I take when installing them.

I'm stuck with a choice - old drivers fantastic tweaking tools or new drivers no tools - GRRRR what are they playing at!!!! Please help!

MINOR

3) Should I have video ram/bios L2 cacheable enabled? It makes no difference to the above problem, but these are the only bios settings I'm not sure about setting (this is NOT shadow into RAM, but telling the computer to allow access to the CPU L2 cache for bios and video ram)

4) Currently I've got the AGP size at 64Mb. Tried it at 128Mb and no difference to the above problems. Should I leave it at 128Mb (half my system ram).

Anyone who can answer any questions please, please help. This is my first system build and I've learnt quite fast but lack veteran experience. The whole build went smooth up to now (apart from a few issues with the infamous 686b sblive! which the new via 4in1's fixed) but this stupid vid card is really getting to me.

PS I've tried installing with the live! Removed but that does not help.

Thankyou for your time. Anyone who can help me here is a star beyond belief, all comments are much appreciated.
 
Have you updated your mobo and vid card bios? Update both of those if not. That might help with the card not working at 4x and fast writes. You might wanna try pushing the i/o voltage up a little and see if that improves things.

As for the drivers and stuff, I don't know what to tell you, except the newer detonator drivers give a pretty good performance boost. I would install those to get the performance increase.
 
Hmm... I had a similar problem with my GF2GTS card and my Epox 8K7A..the video card would only run in 1x/2x and no fast writes... what it ended up being was a jumper set to 100Mhz and not to 133Mhz. The BIOS had a FSB clock adjust which was set to 100mhz initially (because of the jumper). So I set the FSB clock to 133... bad move. What it was doing was overclock the AGP and PCI bus. So setting the jumper correctly fixed the problem. I dunno if the Abit board has a similar jumper, but it's worth checking into.
 
The bios are new on the motherboard and card.

I can get the card to run agp 2x with fast write, so I think I'll leave it at that. The performance difference between 2x and 4x is not noticable anyway, benchmarks are the same - the card doesn't even come close to maxing out the port at 2x. Just look at the prophet 4500 kyro II, it runs 2x.

Anyone out there running an abit KT7A with geforce 2mx at 4x ?

My system is not overclocked and the fsb is at 133 while the pci/agp are at default values (4 divider).

Funny thing is I had the same problem with my last system - getting a matrox G200 to run 2x on a SS7 system was impossible. Had to settle for 1x in the end, even though Matrox claimed it should be at 2x with my board. Slapped the G200 in the KT7A and it ran 2x from the off. Guess some people have all the luck............
 
I seem to recall that I had trouble trying to get the fast write option to work on my board (Tyan S2380). I discoverd that Fast write only works on a few MBs, and mine wasn't one of them. Perhaps trying 4x AGP w/fast write disabled would work better for you?
 
All drivers based on nVidia's Detonator 2 or later have an AGP 4x bug. On VIA chipsets, you'll sometimes need to disable AGP 4x and/or fast writes. No big loss, though: those features have been shown to provide no tangible performance improvement.

As for the drivers, forget the manufacturer's customized crap and get them straight from nVidia. If you need core/mem tweaks, there is a registry setting to enable them, or you can get a PowerStrip-type program.
