Its PC133 CL2, and it will run at 133 at CL2.
I have the same sticks. actually, i have 1, plus the older part that was PC133 CL3, but they both run at CL2 on my system, settings turbo, 2-2-2.
I dont know how it will do above 133, but id set your ram to clk+33 and all settings to the fastest asap!
BTW, it *should* do about 140-145 on CL3, but think the performance hit from CL2 CL3 will make the profit doubtful.
