Melhisedek Posted March 15, 2006 Posted March 15, 2006 With my CPU? Up to 285 it is stable with prime and Super Pi running at the same time (1.5Vcore) but after that Prime fails after a short time, no matter the volts. At the same time RAM is doing just fine with some basic G.Skill DRAM settings I found in some thread. There are quite a few settings @ auto and some are a bit tight (comparing to others at same speeds) but RAM handles memtest without a hitch. Question is can RAM still affect stability even tho it passes memtest? In other words should I start tweaking DRAM settings for increased stability or have I reached CPU limits? Other question is should I increase NB and LDT volts. One is at 1.2 and other at 1.5. Any other stability settings I could try? Thank you for your time!

madu Posted March 15, 2006 Posted March 15, 2006 Did you try both x3 and x4 LDT multies? As far as I have experienced, upping the LDT voltage a notch can help the oc.. Quote Share this post Link to post Share on other sites More sharing options...
AP0ll0UK Posted March 15, 2006 Posted March 15, 2006 That's a nice system you got there I'm still a n00b at overclocking but I'd advise you to put your ram on a divider and then try running Prime again. You can also set Prime to test Small FFT's which will stress the CPU more so than the Torture Test which stresses the CPU and the Ram. Also, are you running one instance of Prime or are you running two, one for each core and then you would get an indication if you have one core weaker than the other. If your ram is passing memtest at 285 then it should be fine tbh and if your running 285 x 9 then that should give you about 2565 clock speed which isn't bad for a 165 from what I've heard. What kind of cooler are you using and what idle and load temps are you getting? Some people say that increasing the LDT voltage can help but other people have said it makes no difference so give it a go and see if things improve. Failing that you could always ask around for some ram timings from someone running a similar CPU and the same Ram and get those into the Bios and see if that helps. Over at XtremeSystems they have a G.SKill tech who will answer questions for you and he could probably suggest some ram timings:- http://www.xtremesystems.org/forums/forumdisplay.php?f=192 Good luck Quote Share this post Link to post Share on other sites More sharing options...
Melhisedek Posted March 15, 2006 Posted March 15, 2006 Sorry guys, forgot to mention I already run with divider. 166 (5/6) And am running x3 LDT. I started with that one to be honest, heard that it should never go over 1000 when multiplied with HTT. Well I'm not so sure about the temps :/ I had Smart Guardian installed but somehow it made my CPU fan stop (I fooled around with fan speeds and such and couldn't undo it anymore) so I uninstalled the bastard. But last I saw was 1.5V @ 2.66 and it was sitting on 47-48 Though my pwm temps were high as hell... about 56+ IIRC What other program could I use to monitor temps/voltages?

AP0ll0UK Posted March 15, 2006 Posted March 15, 2006 Smart Guardian upsets my systems and reports bizarre temps so I've only used it once and not for very long. The best program for monitor temps imo is MBM 5 which can be downloaded from http://mbm.livewiredev.com/ and you can download the NF4 config files from http://premium1.uploadit.org/soundx98//MBMDataFinal.rar What cooler are you using?

Melhisedek Posted March 15, 2006 Posted March 15, 2006 Stock cooler and open case, nothing else. But if I knew wall was because of heat, I would probably buy a better fan, and perhaps add another one blowing over CPU or something... Will check MBM now Quote Share this post Link to post Share on other sites More sharing options...
Melhisedek Posted March 15, 2006 Posted March 15, 2006 Update: Installed MBM and config files (hope it was only matter of putting them in "Data" directory) and running 295 HTT (it was 295 not 285 sorry was late last night) Temps are CPU=51C PWM=63C NF4=52C Vcore is 1.55. Will try and lower it a bit see if o/c stays the same... Quote Share this post Link to post Share on other sites More sharing options...
AP0ll0UK Posted March 15, 2006 Posted March 15, 2006 295 x 9 so that would give you about 2655mhz? If so then thats not a bad overclock I don't think as your now 55mhz faster than an FX-60 which is currently the top end chip that AMD has to offer. If I were you I'd invest some decent cooler. For the CPU the Scythe Ninja with a couple of decent fans can be very effective. I have a Big Typhoon which works well for me until I get a new case with some room for a water cooler. By all means get some fans to improve the air flow in your case as running it with the side panel off isn't always that effective. With the Opteron 144, 146 and 148's, a lot of people removed the IHS in case there was bad contact between the core and the IHS itself. Whether this is the case with the dual core Opteron's I have no idea but it might be something to remember for the future. I removed mine and it dropped the temps by about 7. Your temps do seem high imo but there again I'm not running a dual core CPU so I'd have a look around for other people running a 165 or 170 and see how your system specs, config and temps compare to theirs.

madu Posted March 15, 2006 Posted March 15, 2006 Not on the topic of this thread but wanted to give the link because Ninja cooler is mentioned above... Have look at this before buying a NInja.. http://www.dfi-street.com/forum/showthread.php?t=46674 Quote Share this post Link to post Share on other sites More sharing options...
Melhisedek Posted March 15, 2006 Posted March 15, 2006 Thanks guys. Well I think it might be my core that is the weak link :/ Core 1 to be exact. That is the one that always fails, sometimes faster sometimes slower but it is the one. Core 0 seems to go for ages with almost no regards to voltages. I like core 0 So I guess RAM is not the culprit than. Anything I can do ? I'll look into some more fans (hate loud fans x1900XT is killing me) although I don't have side panel anymore so air flow will not be optimal I guess :/ Quote Share this post Link to post Share on other sites More sharing options...
Smefeman Posted March 15, 2006 Posted March 15, 2006 iT IS most likely your ram since I HAD THE SAME PROBLEM.. my ram was at DDR550 @ 2.8V 2.5-3-3-7 4 hr mem test stable, but no matter what it would not prime stable past 5 seconds until i dropped the timings to 3-3-3-7 but maybe it isnt...

Melhisedek Posted March 16, 2006 Posted March 16, 2006 I see. I'll check it out as soon as I get home. Right now my timing are 3-4-4-8 @ 1T Should I loosen them still, drop multiplier or add some volts? (they are still at stock IIRC... 2.6 I think) Will look some more into DRAM tweaking, hope it helps 2700 is so close Quote Share this post Link to post Share on other sites More sharing options...
