Ocing my little 3700....

[Gynuine69]

Thanks in advance to everyone who puts in their input. Ive tried everything to get this 3700 to OC and for some reason I can't get the thing to run stable at all... BIOS changes, loose timings, you name it. The processor is alil over a year old so i KNOW i can suck some more performance out of it. I tried settings from here: http://www.diy-street.com/forum/showthread...&highlight=3700 as he is using the same mobo and proc as me but I cant figure out the ram settings. Below is my sig as of now. Can anyone bring in some input? I would just like to OC to run a stable rig and get hopefully 15-25% more performance out of it. Thanks for the replies!

Yours memory have pritty tight timings, try to clock down on DRAM Frequency Set so you are on 166 in stead 200, LDT/FSB Frequency Ratio down to x4 an then you kan rise FSB Bus Frequency to the 250 before you are abouve PC3200 limit. Dont try with 250 at the start, its not 100% you kan get there only because som other people did. Try f.ex. with 220, 230, 235, 240 and so on. Dont push to much with Vcore, processor well be unsabile if its to hi. There is other thing, kould be you have to change yor BIOS it kould help for more stability?

thanks for the input.. i appreciate your words. quick question, should i strip down to an inital install (just mobo, proc and ram) before overclocking?

If you have important data back it up then start overclocking.

Gynuine69 if you used the format Kingfisher used and post your settings in this thread people would have an easier time suggesting ideas (maybe they are identical to KF?). Just a thought.

 

Did you drop ram down and test cpu oc then drop cpu then test ram oc ... sorry but can't tell if you did all the basic stuff. You are probably an OC guru so don't mean to talk down to you.

 

I like that strip down idea of yours for oc testing but if it's booting and running it probably wouldn't make a difference with the actual oc.

Thanks for the words.. By no means am I an OC guru and besides, even gurus have to ask questions every once in a while i started from scratch and I am back to testing my cpu OC. So far ive maxed out at 265 x 11 with stock voltage (1.4v). I've thought about upping the voltage a lil bit to see if i can get it higher but Im unsure if doing so will just cause it to become more instable... right now all i have been doing is the HTT or FSB BUS Freq leaving both the mulitiplier at x11 and the voltage at 1.4v. I guess I could ask this: when trying to find your max cpu OC, should i just up the HTT or also change the voltage? Thanks again for the words of input!

If those primary memory timings are too tight and unstable,

 

Try changing them to 3-4-8-3

which BIOS were you using with these settings?

[wevsspot]

Those were with the 623-1 BIOS. However, I feel like the two best BIOS versions for the Ultra-D board were the 0704-2bta or 0406 releases.

Well 2915 is better than good, going on sensational!

 

Are you prime or orthos stable? You can add vcore if you need stability but run Smart Guardian to watch temps. I don't remember what the top safe vcore is, maybe 1.6v but check it out. Heat will likely stop you anyway.

 

You have done well. You can luck out and put in numbers off forums and get great oc but learn nothing. (not that you did that and please don't be insulted, I don't mean it that way) But if you go through all the steps of ram first then cpu setting then tweaks, etc. you get a "feel" for what the system and parts like and you start understanding what the different settings do. I've done it both ways and the slow way is more rewarding but hey, you can't argue with success ... congratulations.

 

There is plenty opportunity for all that step by step stuff when things don't work ... maybe next build.

Haha, thanks for the words man. I actually am doing it the slow way and running prime right now at 2915MHZ to see if it is in fact my max cpu oc. I was tempted to try his settings but a) its a different BIOS and B) i figured since im already clocking higher than his settings at stock voltage and at 40c, might as well see if prime can run stable. And to my suprise, its been running stable for about 5 hours now. Does it matter which test i run by the way? Im running the first of three currently... I am going to run it through the night and see how it goes.. I am sure there will be more questions to come when i move on to my ram settings. Ill be back for an update.
