I know that many people here are very familiar to nVidia products. I'm testing my new system and now have some proboems...

First, my system is...
TB 1G@1G, Abit KG7-lite, 256MB DDR, etc...
LG Studioworks 500 LC TFT 75 Hz max.
Win2k, Servicepack 2, DX8

Previously, I used Radeon LE o/c @ 183/183 MHz core/mem and enable HyperZ... no problem at all...
I tested this config by 2 approach...

1. I set Sachs 3D Aquarium to be the default screensaver at the log-in prompt instead of logon.scr. So when I log-off my PC and go back home my PC would run SS all night. With this Radeon LE = no problem.

2. I set Sachs's SS to be my screensaver. When I left a lot of work (Outlook Express, Excel, Word, etc...) or even no any other work and SS had been launched, it ran smoothly. Again Radeon LE = no problem.

Now I've bought GeForce2Pro 32MB DDR (OEM I don't know its brandname but it is made in Taiwan) and replaced my Radeon LE. I'm testing this card with 2 approaches above. I found that my PC always crash for #2 condition after long run, etc... 1 hr. #1 runs perfectly all night. I tried and tried many drivers (now stop at 12.90), even changed the GPU's heatsink and added heatsinks on each DDR chip + two big fans above the VGA card, with the same result.

Anyway, as I've tested I believe that it's the heat issue of GF2Pro card, especially of the DDR chips (simply check by touching at the heatsink of DDRs, very hot!!!!!). My assumption is that... Radeon LE is unable to be set to "disable V-sync" and so Sachs's SS ran only at 75 fps. For GF2Pro I "disable V-sync" and it runs at 200 fps with a lot of heat generated by each DDR chip. I now "enable V-sync" and, strange... Sachs's SS run at 60 fps (my TFT has the max. refresh rate at 75 Hz, coresponds to the fps at which Radeon LE runs...)

My questions are...
1. Does anyone have any experience like this and how could u cope with these issues. I would like to run Sachs's SS at the maximum frame rate, or ... at the maximum vertical refresh rate 75 Hz... if the max. fps is not possible for this card...

2. How could I "enable V-sync" GF2Pro and set it runs at 75 Hz (75 fps) as Radeon LE can do ??? At this moment when I press the menu button of the TFT monitor to let it shows the current monitor info. it shows that my TFT's running at 75 Hz !!! Why does Sachs's SS ON GF2Pro RUNS AT 60 FPS ? why why why ???

Thanks in advance....

PS: after a lot of tries... I found that Sachs 3D Aquarium is very good for the system test, especially for 3D VGA card run for the long long time. With "disable V-sync" and, no other work run, Sachs's SS could make a lot of load to VGA.

isn't it ???
