Isn't that supposed to be a bit looser? I read that I could run my ram at higher mHz with 2.5 instead of the default 2. There must be more to it than I have read. Not sure what to set my ram speed at to begin with. My system specs are viewable if you care to try to figure my problem out.:toast:

thanks mates
 
2.5 is looser but whats the point theres a performance drop with 2.5 over 2, i wouldnt change unless your sure your ram is causing you a problem

thats good ram looking at your specs whats your problem with it?
 
I don't really have a problem with it I just would like to be able to OC my system to nearly it's maximum potential and I am just trying to cover all the bases. I have read many articles about all this stuff but as a beginner some of it is complicated to understand fully. I read reviews of my ram and saw that people were getting higher mHz with 2.5-?-?-? and I of course would think that is a good thing. :confused: Should I just drop the ram speed down to 166 so that I may OC? My multiplier won't go above 11. Thanks:respect:
 
you can in most cases oc higher with looser timings (i had some old 266 that maxed out with 2.0 timings and it didnt matter if it was 3.0 it wasnt going 1mhz higher) but i dont know a reason it wouldnt work at 2.5 thats odd email the manuf. about and see what they say
