How to make Radeon X1300 work with NForce4 chipset
EDIT2: The bug is still not discovered. Well, in both cases the nForce4-4X chipset is used. I found today 4 different classes of nForce4 drivers. I will try further investigating there. (well, both MSI and ASUS boards do this, do you think Sapphire VGA is the cause???)
EDIT: most probable cause was thie BIOS from 10/2005 which did not recognize the AMD processor from 11/2005 - well, there may be some other fine-tunings too. So new rules are: if the BIOS doesn't know your processor's name, you HAVE TO upgrade! (this used to be an option before)
Problem: Call of Duty causes total freezing of computer while playing or doing rapid moves.
Suspected cause: I suspect some buffer overrun. The HTT is 201MHz by default, PCIe 100MHz.
See my post to ATi:
I found a fix for the X1300Pro which freezed even under the today released Catalyst 5.13 drivers. The solution was simple. As the computers I install the X1300Pro run all Nforce4 chipsets, the HTT of the CPU is 201MHz... so I thougth if 100MHz PCIexpress is enough. After increasing it to 115MHz no longer any crashes! (ASUS K8N4-E) With MSI K8N Neo 3, where I met the problem first, I decreased maximum payload size to 128 (from 4096 default) and number of links from 16up and 16 down to 8+8. Again, Call of Duty was fixed.
Since the ASUS does not have these settings in the BIOS I had to find the "increase PCIe frequency" fix.
