Vampire Posted May 20, 2004 Posted May 20, 2004 (edited) Ok, I wanna tighten my ram timings, at stock they are 2.5,4,4,8 (Kingmax ram... not too good), but I am running my PC3500 ram @ PC3200, so should I be right running them @ 2,2,2,5? (Heard thats best for P4) Will I need to increase the voltage? Also how do I check for memory stability? thx EDIT: Help! I set the ram to 2,2,2,7 and then rebooted... now its not even getting into bios so I can put the timings back to normal... what do I do... clear the cmos? I think thats what I gotta do but I dunno how to do it.. do I put the jumper to the reset position then turn the computer on... or leave it off or what?? HALP EDIT 2: Ok back to completely stock settings now after resetting the CMOS... guess my ram cant handle those sort of timings Edited May 20, 2004 by Vampire Share this post Link to post Share on other sites More sharing options...
kendellrt Posted May 20, 2004 Posted May 20, 2004 Your RAM may not be able to handle cas 2, keep trying with cas 2.5, and adjust the other settings acordingly. Share this post Link to post Share on other sites More sharing options...
Vampire Posted May 21, 2004 Posted May 21, 2004 Ok, what should I try to aim for... whats the best timings for p4 with 2.5 CAS? Share this post Link to post Share on other sites More sharing options...
TheSternMystic Posted May 24, 2004 Posted May 24, 2004 Hmm, is it a P4 or AMD? I've got an Old Dell laptop with some Micron ram that has timings of 2-2-2-5... Share this post Link to post Share on other sites More sharing options...
hardnrg Posted May 24, 2004 Posted May 24, 2004 you could always turn to maths... 3200/3500 is only about 91%... so you won't really be able to change your timings MUCH... you might be able to change them down by one if you get lucky with a bit of extra voltage... the timings that aren't CAS latency don't make much difference at all if you want 2-2-2-5 you'll have to buy some of the more expensive low-latency ram (or look into some cheap ram with decent memory chips) if your sig is up-to-date you might be better off giving your cpu a bit more juice than 1.55V (isn't that really low?) and nudging up the fsb...

Vampire Posted May 24, 2004 Posted May 24, 2004 Yeh well my chip doesnt like the FSB going too much higher... but it is rock stable as in my sig... It does 3.5ghz on stock vcore but after a while in prime95 crashes and also crashes on intense games such as farcry, UT2k4.. its perfect though as is. I know my ram is bad (kingmax), I didnt see a point to getting extremely expensive corsair stuff, but now I know I probly should have. Ok, I tried 2.5,3,3,7 @ 200mhz and its going ok... cant see a performance increase though. RAM these days is just so expensive! I could buy an X800 pro for the cost of premium ram (1Gb) Share this post Link to post Share on other sites More sharing options...
JackRussell Posted May 24, 2004 Posted May 24, 2004 if your sig is up-to-date you might be better off giving your cpu a bit more juice than 1.55V (isn't that really low?) Yea it's one notch above default. I've wondered about that vcore myself. Not that it's impossible to have 1.55v @3.5, but how many hours stable is that? Prime95 can turn up a rounding error even after several hours (or even days supposedly). I checked my 3.43 overclock with 29 hours (maybe overkill but nice to know).

Vampire Posted May 24, 2004 Posted May 24, 2004 8 hours... didnt bother going any further. Its stable in my books... cant see anything wrong with it Share this post Link to post Share on other sites More sharing options...
JackRussell Posted May 24, 2004 Posted May 24, 2004 Just thinking low vcore could be contributing factor (to why you had to resort to reseting CMOS). Share this post Link to post Share on other sites More sharing options...
Vampire Posted May 24, 2004 Posted May 24, 2004 possibly... I think Ill just have t accept I have bad ram and leave it @ 200mhz, 2.5-3-3-7 thx guys Share this post Link to post Share on other sites More sharing options...
hardnrg Posted May 24, 2004 Posted May 24, 2004 it is rock stable as in my sig... It does 3.5ghz on stock vcore but after a while in prime95 crashes and also crashes on intense games such as farcry, UT2k4.. its perfect though as is. if prime95 crashes it isn't stable!!!! man, i ran prime 95 and it crashed after 13 hours... on the same settings i ran UT'04 and it crashed in about 15 minutes. that's not what i call perfect! one notch above default??? at THAT o/c???? are you mad???! for the love of god, up that vcore! timings, schmimings... up the vcore til its stable at least, then try a further o/c... do-able and much more potential than fooling about with your timings... up yer vcore and use MBM5 to monitor yer temps and run prime95 for at least 12hours and more like 24+ hours when you think it's all stable... i really think UT'04 (and other new games like FarCry) are like accelerated torture tests... prime95 keeps testing the same thing over and over for ages and then switches to something else after a while... games just switch about more often i think... how can you live knowing that your game might suddenly crash at any time??? craziness!

Vampire Posted May 24, 2004 Posted May 24, 2004 LOL! Ok, well although extremely off topic, what vcore do you suggest? Share this post Link to post Share on other sites More sharing options...
