skuzzy,
some interesting info for ya...
i have:
P3V4X
256meg PC133
PIII600E OC'd to 900mhz (150fsb)
Geforce2 ULTRA 64meg
ran 3dmark2000 with a score of ~7500
here's the somewhat interesting part...i had access to a PIII933 (slot1, and is NOT clock locked) for the night. Using the same setup as above (only now the 933 chip was installed) multiplier of 7.0 x 133fsb 1.75v.
3dmark200 score was ~7600 (i can't recall the exact numbers off the top of my head, but the first 2 digits are correct.)
all tests were done in AGP2X (AH locks up when in 4X mode, but 3dmark2000 WILL run through in 4X, i just didn't test it)
i know you are testing the cpus as is, no OCing. But i just wanted to throw some info at ya.
side note 2: Asus says that the P3V4X is for 733+ cpus. Since the 933 was not clock locked, and in the bios settings there was an option to set it at 866 (for auto mode). When i have my pIII600E in place i have the options of 400, 600, 800, or manual. I can only assume that if i had an 866 that the bios menu "should" show an option for it.
anyhow....can't wait to view your results on the testing! and a big thanks for knowledge and help!
