Fanatic Posted September 30, 2004 Posted September 30, 2004 Quick question. Will Prime 95 show the system stability? OK 2 quick questions then. If it does where can I get it? Share this post Link to post Share on other sites More sharing options...
cmac Posted September 30, 2004 Posted September 30, 2004 yes it will test the stability of your over clock if it runs 24hrs with no error your in great shape, http://www.mersenne.org/freesoft.htm cmac Share this post Link to post Share on other sites More sharing options...

serv Posted October 1, 2004 Posted October 1, 2004 been running for bout 16 hours so is it safe to assume that my slight OC is fine? and rdy to go higher? Share this post Link to post Share on other sites More sharing options...
Leldorion Posted October 1, 2004 Posted October 1, 2004 I would say so serv. Share this post Link to post Share on other sites More sharing options...
markiemrboo Posted October 1, 2004 Posted October 1, 2004 I run it for 5 or 10 minutes, max heat if i'm twiddling the multiplier, blend if i've twiddled the FSB (test RAM). If it doesn't poo up, raise more until it does. Try more voltage etc etc. Once i've found an overclock that doesn't poo up after 5 minutes i'll leave it overnight. It's worth leaving overnight too, i've had one that ran for only about.. 5 hours. I'm at 231MHz FSB but like a 9x multiplier 1.4v right now (need a new PSU) that's been folding for 2 weeks without error now... so i'd say my FSB is stable atleast Share this post Link to post Share on other sites More sharing options...
serv Posted October 1, 2004 Posted October 1, 2004 ok ready for another OC, currently 105MHz FSB 20x multiplier (i think lol), erm when wud i need 2 increase the voltage, think its currently set at 1.75 ? Share this post Link to post Share on other sites More sharing options...
markiemrboo Posted October 1, 2004 Posted October 1, 2004 When it fails prime rather quickly, then's the time to fiddle with voltages Share this post Link to post Share on other sites More sharing options...
serv Posted October 1, 2004 Posted October 1, 2004 Ok been messing about with my FSB settings to see what esle i can squeeze out of this CPU, currently 105MHz FSB 20x multiplier, so i changed it to 115MHz FSB 20x multiplier which would have given me 2.3GHZ, but PC just rebooted itself a few times, CPU temp was fine tho was a stable 42, so i adjusted the FSB to 110 x20 multiplier giving me 2.22ghz, running Prime 95 again to make sure its stable. when rebooting my PC i notice on the 1st screen of boot up it says my VCORE is 1.69v but Sisoftware says its 1.75v, ok my point is lol if the PC reboots shud i try altering the VCORE voltage ? and what way do i adjust it down or up ?

markiemrboo Posted October 1, 2004 Posted October 1, 2004 Yeah, i'd give it a try with more voltage. Don't go crazy with the voltage though!!! The 'safe limit' for an Athlon XP, which has a stock 1.65v, is 1.85v. Something like 10% more? I'd say don't go over 1.9v if stock is 1.7v, but only providing your temps stay lowish (under 55C?). More voltage... = adjust it upwards obviously I don't think BIOS and Software voltage readings are always all that accurate. What's it set to in BIOS? 1.7v? Is that it's stock setting?

serv Posted October 1, 2004 Posted October 1, 2004 ok just checked my VCORE voltage, its changed again its now 1.71 it was 1.69 last time i looked, in another setting it says VCORE Voltage DEFAULT, so im thinking that its automatically adjusting itself ? and yeah my CPU temp is fine still early 40`s with the CPU @ 100% with Prime95...
