Please give me your thoughts.

I have a Radeon 8500 and was running the 6043 drivers. I am using an Intel 1.8a P4 and an Intel 2.4ghz Northwood B Engineering Sample (both produce the same bug). The rest of my system specs are below.

My card is pencil tricked (1.9 Vcore, 3.85 Vmem) -- the card has an Alpha 1U CPU Heatsink on the core and Aluminum Ramsinks (it runs very cool).

When I run the sytem at 100 fsb with either chip the system is stable and completes 3dMark no problem.

However, when I run the system at 133 fsb (with the Rambus at 3x or 400 mhz -- not overclocked). The system will eventually blue screen and give show an error on the ati2dvag.dll. So at 133 fsb (which by the way is stock fsb for the ES chip) the system will crash even when not doing graphically intense programs (i.e., jsut browsing and running Prime 95).

I uninstalled the 6043 drivers and did not load any new ATI drivers -- I am using just the standard VGA adapter drivers. With no ATI drivers the system is rock stable at 133 fsb on both chips. I ran torture test for 8 hours on the 1.8a and have been running for about 6 and counting on the 2.4 ghz ES. With the ATI drivers installed the system will blue screen within minutes.

BTW, the Card is running at stock speed and the AGP ratio is set to fixed at 66mhz (a nifty feature on the Abit TH7II). I do have Fast Writes enabled in the bios (could that be the source of instability). I have a 128MB aperture, and the other settings I can't remember but they are default.

My PSU is a PC Power & Cooling 450ATX and the 3.3V and 5V rails never vary from 3.3 or 5 respectively. The 12v rail does dip to 11.85 on occasion -- but I do not see how that could effect the card.

I believe my instablity is Radeon and/or Radeon driver related -- but I can't figure out a work around. Please help!!!!

I am about 1 day way from jsut giving up and selling the card (an excuse to upgrade to a Ti4600). Please prevent me from going Nvidia.

I will try those -- but I hear they are buggier than the 6043's (i.e., texture and polygon errors in Max Payne).

Skrill,

Read my post about the infinite loop issue, there's something in there you should note:

The driver developer I spoke with at ATi support told me that the AGP Aperture MUST by set to 64MB in the BIOS,
or the ATi drivers will NOT install correctly. That should be your first step, after you try that, get back to me with your
results.

The unofficial 6052 drivers are what I'm running right now, and they're fantastic, although I had to disable the VIA 4x
to make it stable. (The performance hit was so unbelievably small that I won't even bother to mention it.)
