Zxian Posted January 23, 2007 Share Posted January 23, 2007 So here's something for people to scratch their heads over...I recently got my hands on a nVidia Ti4200 that I was planning on using to upgrade my old system (from a RIVA TNT2) . After installing it, I noticed a decrease in performance.After quite a bit of digging, I realized that I was suffering from the dreaded PIO Mode problem... I tried to do the whole thing of uninstalling the IDE Controllers, setting that registry entry to reset the error count, etc etc etc. No dice. I checked in BIOS, but all settings were correct. Tried changing some settings - no dice.Swapping the old card back into the system made the drive run at UDMA-4 (the max of this mobo). I can't really figure out why this is the case. Could it be a lack of power for the AGP 4x slot? The PSU checks out, and isn't running anywhere near it's limits (drawing about 90W from a 300W PSU). MBM is showing my 12V as pretty high (12.7), but I'm going to check the BIOS when I get home (I trust BIOS more than software). Link to comment Share on other sites More sharing options...
nmX.Memnoch Posted January 23, 2007 Share Posted January 23, 2007 (edited) Odd...You should have plenty of power going to the AGP slot for that card.Which NVIDIA drivers are you using?And what are the specs of the rest of the system (mobo chipset mainly)?

puntoMX Posted January 24, 2007 Share Posted January 24, 2007 Problem with VIA chipsets for PIII and Athlon.I had the same problems with a FX5200 few years ago. Only thing you can do is to reinstall the 4 in 1 drivers from VIA, if that doesn´t help remove the controllers in your hardware list and restart you computer...Let us know what you found out .

Zxian Posted January 24, 2007 Author Share Posted January 24, 2007 Well that was dumb of me... at least I think I have the problem fixed... AGP Aperture size was set to 64MB... this is a 128MB card... I've set it to 256MB now - and both drives are running in UDMA. @puntoMX - you're right - it's a VIA chipset. It's the ASUS CUV4X motherboard with a PIII 700 and 1.5GB of PC133 (I know - totally lobsided).I'll let you guys know how Mechwarrior III goes...

puntoMX Posted January 24, 2007 Share Posted January 24, 2007 Who could have thought that? By setting the AGP Aperture size to 128MB or higher fixed it... freaking VIA chipsets... Link to comment Share on other sites More sharing options...
Zxian Posted January 24, 2007 Author Share Posted January 24, 2007 Well... kinda makes sense... 128MB card = 128MB aperture or higher. All the other video cards around here are 32MB, so the usual default of 64MB has been fine for me. Link to comment Share on other sites More sharing options...
