Safe OC'ing for Crucial PC2100

Is it possible to get ddr 333 out of this ram?

I have ran my Crucial DDR2100 at 132fsb with a 3:4 multiplier or DDR352. I can't say your stick will do the same, but its definately a good possibility. Its currently only running DDR290....... It makes my tray pop out on my CD Burner when it boots into WinXP if I run it at 145fsb with a 4:5 multiplier (DDR362.5).

But I am running 2 6 2 2 timing at DDR290 so it ain't all bad.......

I don't have Crucial RAM specifically, but I have run Micron RAM(Same chips as Crucial but maybe a bit lower in quality) at higher than 166 with the memory timing at the most aggressive that I could set them to. I am running an Epox 8KHA+ for a mobo. I think that I got up to 170ish before I started to see instability.

The big trick is to turn up the voltage to your RAM as you start to see instability. I won't personally run the voltage any higher than 2.9 (2.5 is stock and 2.6 is default on most mobo BIOSes). There are comments and articles out there that say that 3.0 is fine and those that say that it is bad to go to that or higher. My suggestion would be that if you want to try going past 166(333), that you invest in some heat spreaders for your RAM. Thermaltake makes a decent kit.

Straight up, 166(333) should be no problem for the Crucial brand RAM. Micron reserves the best chips from the factory for that brand of RAM.

Play safe and have fun!!!!
