I'll make graphs for them when I'm done.

Here is my rough outline of what I plan to do:

http://home.earthlink.net/~eckyx3/test results.doc

I'm trying to find out what the memory bandwidth requirements are for an X2, and I'm using two different speeds in order to see if that bandwidth requirement changes, and how much.

Any suggestions? Other tests? I don't mind doing more, it gives me time to watch some anime.

EDIT: Results will be delayed a bit due to excessive schoolwork and the fact that I have to re-do the video tests. My X1800 is coming in tomorrow, and I think that might skew results a bit.

interesting.

i'd add this info from the data sheet to the first post:

2x 1024MB Mushkin Black – 128bit - rated 250MHz @ 3-4-3-8 (timings are a constant)
Ati Radeon X800GTO² flashed to 16 pipes, clocked to 560/560

for easy reference at a glance for those who would come back to this thread...

Sounds interesting, and I'm looking forward to seeing the results, especially since I shall be making the X2 plunge sometime soon. Subscribed

sounds like alot of work,and an interesting read when all the research is done.
