L2 speed question on a Athlon 900

[DragonFire]

I was wondering if any one knew what speed (in ns) the l2 cache chips were on a Athlon 900?

The multiplier should be 2/5 on a non Thunderbird Athlon. Probably 2 or 3 ns.

actually, on classic athlons greater than 850mhz, the multiplier was dropped down to 1/3. To get the NS rating, you need to take the inverse of its clock speed, or 1/300mhz (because the clock is 1/3 of 900mhz), which turns out to be 1/300,000,000 which is 3.33 (repeating) NS. So you're pretty much garunteed to have cache that is rated for, at worse, 3.3 NS. Chances are, you have something better.

Better......ahahaha.....try 3.5 ns.....I was just wondering what the norm is for 900's.....

Well, I know that when they make cache chips, like everything else, they do have a bit of tolerance...but quite frankely, I'm suprised they'd do it that far. I thought that 3.4 would be the slowest that they'd do...sheesh.

Well, I guess you got cache chips with a crappy ns rating .
