soccrstar Posted December 24, 2002 Posted December 24, 2002 cooling problem perhaps the board dont Overclock u check current cpu temp? most common problem for overclockin' problem is RAM i have a 800 tbird downstairs and i can OC up to a certain point like 824mhz or somethn' if i try settin' the FSB to 133mzh it wont post its because of the ram i know that its bad. i got sold a defective ram. so try changin' ur ram and check timings. hope that helps Quote Share this post Link to post Share on other sites More sharing options...

mastermind Posted December 24, 2002 Posted December 24, 2002 greetings the situation described above by the esteemed psywar is actually my situation, i thought i'd add a little more information to see if it helps, first my setup: abit at7-max mobo, 512mb corsair 2700 ddr ram (2x256 sticks), athlon xp 1800 palamino core. thermaltake slk-800 w/ vantec tornado and arctic silver 3 for cooling. i'm pretty sure that cooling is not the issue here, i have been running at stock frequency since i put the new heatsink on and i have yet to see it go over 50c in any situation, it's usually around 38-40. as for the ram, it is corsair which is arguably some of the most reliable stuff on the market, and i'm not even going with really agressive timings on that either (cas 2.5, 3-5-2, 1T). like psywar said above i change the cpu settings in the bios and boot into windows fine, but as soon as i shut down i have to clear the cmos to get it to post again. and i've tried all sorts of combinations too, fsb's from 138 (a measly 5mhz oc) up to 166 (an even 33mhz oc), with various vcore settings and with and without ram tweaking. everything i do produces the above results. any suggestions would be greatly appreciated...

DevilMB3017 Posted December 24, 2002 Posted December 24, 2002 Have you tried setting the CPU/Memory ratio differently? A 4:5 setting or 4:3 setting might fix the problem. Quote Share this post Link to post Share on other sites More sharing options...
