overclocking dilemma


Recommended Posts

I can't seem to get past 205fsb at 1:1 on my asus p4c800 deluxe w/ the twinx 1gig 3200llpt 1.2v (2,2,3,6 timings-2.75v) modules. i'm using p4 3.0c 800mhz at 1.625v.... i have to notch it (ratio) down a bit to 5:4......with this, i'm able to go up to 230fsb (from 3.0ghz to 3.45ghz)! haven't tried going past this yet.... i have another twinx 320llpt 512mb 1.1v (same setup) that's able to go up to 230fsb at 1:1, no sweat! can someone school me on this one? I don't get it...

Actually, it sort of makes sense... Rev 1.1's are Winbond Rev B IC's and Rev 1.2's are Rev C IC's, which have different "top" performances. I'd try relaxing your timings (2.5-3-3-6) and increasing the DDR voltage to 2.8 volts and see what that does for you. PLUR CK

Thanks for the reply CK. I tried your advice...unfortunately my comp won't POST if my ratio is at the 1:1, fsb of 210, timings and volts as you recommended. When i adjust the ratio to 5:4, everything works well. so... Rev1.1 twinx-1024 3200llpt modules can hit at a higher fsb then rev1.2 at ratio 1:1? Since i have the rev1.2 modules, am i limited to the 5:4 or lower ratio? Are there modules in the market right now that can achieve 1:1 ratio w/ fsb of 230+? I read an article in anandtech, that it's useless (overclocking) if the speed of your memory and cpu aren't in sync or 1:1 w/ each other...is that true? Once again, thanks for your help.

Im using a asus P4C800E-Deluxe with Corsair TWINX1024 PC3200LL Rev1.1 and they run 230+ FSB 1:1 ratio with PAT and Turbo on at 2.85v easy , Prime and Memtest error free. Note my last mobo (MSI 875 NEO FIS2R) wouldnt do past 223FSB with the same settings, Also my benchmark with the new mobo is really showing off this rams potential , getting over 5700 im Sandra (Old board 5100ish) Rev 1.1 use the "Famous" BH-5 IC's which would out perform the Rev 1.2's.
