I have a system based around a C2D e4300 (LS9TB Q705A195) now cooled by an AC 7 Pro air cooler, on an Abit IB9 MB with DDR2 PC6400 memory. I put this system together a few months ago and I have very happy with it. However I would like to see if I can increase the performance a little further but have been unable to do so without assistance. While I have read a lot about it, I am still a VERY rudimentary over-clocker. I am not sure if I have reached the capabilities of the hardware or just my ability to over-clock.
System is currently running a 340 bus speed x 9 multiplier resulting in 3060 Mhz. I could run 340x8 when setting N/B strap=1066 and cpu:dram=800 (2:3) but still couldn't get higher than that, even when maxing MCH voltage to 1.45. Whenever I try to increase the bus speed further it will generally boot but the bus will show either the previous setting or will revert to 199. I have experimented with many settings but I lack some basic understandings of how some of the settings interact, such as the memory speed.
Here are some settings I have been using. I am not sure this is right but when I change it I generally get bad results, like no post, the machine screaming and have to reset CMOS. I have also tried upping voltages and this has not helped. I might be able to back off on some of the voltage at current settings, I'm not sure, I will experiment with that later if I can't increase the bus any further. I am particularly unsure about top two settings below as I don't understand them and they don't LOOK right to me, but again, this is what has yielded my best results to far. I currently idle at around 47 degrees and load at 60. Also I do not see a memory multiplier setting which I often see referred to, I am thinking this is probably the equivalent of my setting “ CPU😀RAM”.
340x9=3060
N/B stap CPU as: PSB 1066
DRAM spec (CPU😀RAM) DDR2 533 (1:1)
CPU voltage: 1.4
Ram voltage: 2
MCH voltage: 1.4
Any suggestions on other setting combination I might want to try?
Thanks so much !
