Pianist Posted February 9, 2006 Posted February 9, 2006 Hey all, I have a question. I am using a 4000+ san diego chip and while testing for max mhz, i could not pass 12x230 on 1.55 volts. Im now on 1.59 and its just finished Superpi 32M. What I want to know is could it be anything to do with the ram when i was on 1.55 that would stop me. I read the guide and have expiremtned with clocking before. Set the HTT to 3x, ram to 100. If not, is 1.595 an alright voltage to run pc at 24/7? Temps are no problem with big typhoon maxing out at 39 deg from superpi. Once I find the max mhz of 1.595 I will prime it. (Aiming for 2.8). Thanks edit - im actually using the 704/2 bta bios Quote Share this post Link to post Share on other sites More sharing options...
claydawg Posted February 12, 2006 Posted February 12, 2006 I am running 12x238 on my 4000+ SanDiego perfectly stable. My max CPU speed I found when starting to overclock 2916 @ 243x12. I'm only running 1.525V to my CPU. How much juice are you giving your RAM? I'm running 2.72V, but if you check my sig you'll notice that your RAM is better than mine. Running that high of a voltage to your proc should be ok as long as you have the cooling for it. I'm sure I could have maxed my CPU higher in my initial tests with more power, but I liked both the speeds and temps I was posting and there was no point b/c my RAM wouldn't go past 238mhz stable, unlike yours lol. Just watch your temps and you should be fine, there are several people on these forums I've seen running ~1.59-1.6 on SanDiego cores. Good luck man!

I have a similar setup and will be oc'ing in the near future, i wasn't expecting to be able to break 2800 on air. Quote Share this post Link to post Share on other sites More sharing options...

I have a similar setup and will be oc'ing in the near future, i wasn't expecting to be able to break 2800 on air. I was surprised, I highly recommend the Arctic Cooling Freezer 64 Pro. With my OC, I sit around 25-27C and on full load I'm at 38-41C. I'll start a thread and post pics if you like, I don't wanna hijack Pianist's thread.

olympic Posted February 13, 2006 Posted February 13, 2006 My 4000+ ran for about 2 months at 2700MHz with 1.65v on water. Then the memory controller fried and it wont run at anything over the stock 2400 now. Stay below 1.6v and you "should" be OK.

Pianist Posted February 13, 2006 Posted February 13, 2006 Ive tested the ram on memtest and its stable so Im pretty sure its just the cpu. Quote Share this post Link to post Share on other sites More sharing options...
claydawg Posted February 13, 2006 Posted February 13, 2006 Did you drop your LTD and Use a 1/2 divider on your RAM while testing CPU max? Quote Share this post Link to post Share on other sites More sharing options...
