Help oc'ing my new rig

Hi guys, I've never overclocked an athlon 64 before so bear with me. Im running a gigabyte k8n-sli with a 3700+ san diego and 4*512 value ram. I understand that I shouldnt expect anything at all amzing from my ram but I don't seem to be able to oc at all. In my BIOS there are two menus I am using to overclock. "advanced chipset features" and a menu offering all the cpu settings. I cannot find a divider setting anywhere but it allows me to set the ram fsb speed and the processor one seperately which i assume is the same. leaving my ram at 200mhz and increasing the cpu to 220 leaves me unable to post. Even if i slacken every ram timing to the largest amount possible I barely get any where. Please help guys as I know i should be able to get something decent out of this cpu.

Drop the ram fsb speed - its just a different name for the divider, with 200 being 1:1. Drop the HTT to 4x to keep HTTxFSB < 1000 and up the CPU FSB.

ok, thanks for the reply. I also updated the bios and it seems to have many more features too.

okay, well with the BIOS update i now have the divider function and it shows the relative memory speed as you tinker with the cpu fsb which is nice. More to the point I still can't get anything out of my chip, is there a setting I'm missing, I assume I wouldn't need to alter any voltages for a 20mhz increase, and RAM timings can be ignored as im using the divider. ANy help is much appreciated guys.

I've managed to run at 250mhz fsb but I can only have HT at 2.5x or it refuses to boot, how much will this affect performance?

Drop the memory to 133 to take it out of the equation. Drop HTT to 3x and see. Use cpuz to see what speed the memory is running at.

ok, I'll try that when I get home from work. Thanks for the help :cool:

also try with just one stick of ram

surfsquid · 26 Mar 2006 at 19:48

well I tried both of those and still no go, I would like to use a higher HT multiplier as there seems to be no performance gain between running my processor at stock and running at 240FSB with a 2x HT multi.

Defcon5 · 27 Mar 2006 at 08:57

what benchies have you done to come to that conclusion?

surfsquid · 27 Mar 2006 at 12:40

Well to be truthful I've only run a couple of 3Dmarks, maybe i should use superPi?

Defcon5 · 27 Mar 2006 at 14:45

yes definatly, you are limited in your 3dmark score by your gfx card

i recnetly read an artical on HT multis and it seems that if it is set too low it hardly makes a difference but if its to high it will cause big problems so i wouldnt worry about setting it to low, 3x is fine
