Kingmax PC2700 5ns cas2.5 - 2x 256mb
(all cas settings by SPD)

SciSoft Sandra Memory Test
100fsb 1:1 200ddr cas2,2,2,5 = 1487 / 1463
133fsb 4:3 200ddr cas2,2,2,5 = 1466 / 1439

100fsb 3:4 266ddr cas2,3,3,6 = 1994 / 1967
133fsb 1:1 266ddr cas2,3,3,6 = 1966 / 1933

100fsb 3:5 333ddr cas2.5,4,4,7 = 2275 / 2242
125fsb 3:4 333ddr cas2,3,3,6 = 2473 / 2439
133fsb 4:5 333ddr cas2.5,4,4,7 = 2474 / 2437

132fsb 3:4 352ddr cas2,3,3,6 = 2593 / 2560

Overclocking
116fsb 3:5 386ddr cas2.5,4,4,7 = 2635 / 2600
120fsb 3:5 400ddr cas2.5,4,4,7 = 2720 / 2685
128fsb 3:5 425ddr cas2.5,4,4,7 = 2902 / 2870 !!!!!

116fsb/386ddr was the memories maximum obtainable speed on 2.5v.
128fsb/425ddr was the memories maximum obtainable speed on 2.7v.

VERY NICE!

I have mine at 148 FSB, vcore 1.6500

My memory ratio is set to auto in the bios. I am getting 2600/2600 or so in Sandra Memory benchmarks

I have the same motherboard, memory and a 1.6A Chip

Nice!
Thanks for the info, mine seems to be on par for a 1.6a then.

145/181 A
145/181 B
145/181 C

133/166 A
133/166 B
133/166 C


Memory by SPD also.

Edit-
A is CPU Arithmetic
B is CPU MultiMedia
C is Memory Bandwith
