PCI to DRAM prefetch

it seemed to make my system more stable running intensive 3d applications. What is it? nothing on rojakpot's BIOS optimization or anyother i could find out. does that make the DRAM to begin processing the next PCI data by prefetching it?

oTTO, you always ask tough questions, and sometimes have some tough answers... I was checking here for an answer to see you posted a tough question .

I'll check back later for an answer.

A bump cuz I wanna know too. I saw that in my BIOS

I found this info on the thread subject if it helps:

PCI-to-DRAM Prefetch (enabled)

In order to avoid repetitive accesses to the system memory for retrieving small pieces of data, an entire area of memory can be prefetched, based on the locality of coherent data. This means that the data are already in the buffer before they are needed and can be accessed with very low latency. This mode can enhance sound card and IEEE 1394 PCI card performance.

ok, it helps a lot. thanks.
