Overclocked Geforce 2 - Reboots

[Stiffler]

Hi there I am running a PIV 2.4B at 2.81GHz (Vcore 1.6) and a Gainward Geforce 2 Ti500 GS Card at 296MHz core & 507MHz Memory.

I have the system running totally stable at this and I have left it running programs for long periods of time withought any issues. There are no signs or any artifacts yet if I try and increase the Ram or core (independantly of each other) the system reboots while trying to load Game 2 or 3 in 3DMark2001SE. The Games run fine and it only every reboots during the loading. I was wondering if this could be anything to do with the AGP voltage ? Or has the Card just reached it maximum ?

The system is on a Asus P4S8X with 512MB or Corsair DDR 2700.

ps: Does anyone know why my CPU temp is reported at 27 idle and 37 under load (both in the BIOS and via Asus Probe? I believe this is wrong, but how much higher is my true temp ? HSF is a Thermaltake Volcano 7+ running at 5400rpm (not full speed)

First of all remove Asus PC-Probe and install MBM5 from <A HREF="http://mbm.livewiredev.com" target="_new">http://mbm.livewiredev.com</A> and use that as hardware diagnosing tool.

You can try to increase your AGP Voltage with jumpers of inside the BIOS. But I don't know what your normal videocard speeds are but maybe you just reached the max.


My peltier is so powerful I get Bose-Einstein Condensate beneath it .

What are the default speeds of that video card? and are you using any extra cooling for it?

BTW, just to remove confusion I think you have a GF3, not a GF2.

My sig's faster than yours, and it overclocks better too....

Well then he has to reinstall the drivers, because 3DMark2001SE sees it as a GeForce2 Ti.

Hi there

1. Thanks svol but I have used MBM for a long time now and if it worked on this Asus P4S8X I would be using it. There is still no support for the SIS chipset by Alex van Kaam. Besides the Bios readings of the temperature are exactly the same :/ !

2. Thanks for trying to confuse matters further tombance, but no you are not helping, it is a Geforce <b>2</b> Ti500 (Self titled by Gainward) essentially it is a normal Ti with some faster RAM and higher clock speeds. <A HREF="http://www.hitech-solutions.com/images/products/gainward_gf2ti500.jpg" target="_new">A Picture for the Non believers !</A>

I would appreciate not being treated like an Idiot...

Ok the default clocks are : 261MHz Core and 472MHz RAM

The card comes with a Gainward HSF and ram sinks so I haven't bothered with extra cooling, <A HREF="http://www.gamestar.de//graphics/bild_db/1700/1794/PopUp_640x480.idg" target="_new">A Picture of the card</A>.
Its housed in a Chieftec full tower with 6 System fans (one of which is a 80mm side fan blowing directly onto the top side of the card) and a PCI exaust below it.

My question is I suppose, what are the effects of adjusting the AGP voltage... it is something I have never had an option to do before and thus never tried, there are choices of 1.5, 1.6 and 1.7 available.

The default voltage of the AGP port is 1.5V and I think increasing it will do the following: if you increase the voltage the card can be supplied with more power, so if your card needs more power to run at a higher GPU speed or memory clock this can help you card get enough power to run it.
I would suggest increasing it to 1.6V and then trying to increase the GPU or memory... if this doesn't help you probably reached the cards maximum stable speeds.

Just my experience with Geforce 2 overvolting:

GF2 MX 400-D (32 MB DDR 64-bit) RAM heatsink and fan added to GPU/RAM
Default: Core: 200 MHz RAM: 200 MHz (400 DDR)

Overclocking at 1.5V: Core 250 RAM 495 DDR (3DMARK improved 17%)
Overclocking at 1.8V: Core 250 RAM 500 DDR (3DMARK improved 18%)


As you see the extra volts really don’t give any big OC/Benchmark improving.
