Newbie overclocker

post #1 of 7
Thread Starter 
Well, broke down and tried my hand at this finally. Read thru lots of the threads here, and (hopefully) I've done it right. First, I tried the ASUS AI overclocking utility in the Bios. 5% o/c gave me3.21mhz, and things ran stable, and temps never got over 40C. After reading about the possibility of the progrram raising AGP/PCI voltages, I went into the bios, and made some changes myself.
Currently, running at core voltage of about 1.66v, (although my cheap POS PSU fluxuates to 1.55 sometimes. that's scheduled for replacement.)
FSB is at 599/600(149.9x4) So far, after 4 hrs of Prime95, the OCCT test and 1 hr of their stress test, temps never got over 42, with idle temps in the low 30's.
Anthing I'm overlooking? Any tips or suggestions? Anything that raises a red flag?

Looks like a decent beginnings--as long as your temps are stable and you have your PCI AGP locked you might want to try underclocking the RAM by choosing the next lowest speed in BIOS and pushing the FSB even further in small increments. Rasing the VDimm will help stabilize the system.

Good luck and keep us posted...
EDIT: add another stick of RAM to keep your Dual Channel thing happening...it only works in pairs and you have3 sticks

Sorry to sound dumb, but this ain't my area of expertise...I looked in the bios, and the only options I find for Dram Timing is 266, 333, and auto, which apparently defaults to 333, since my processor has a 533 FSB. Am I not looking in the right place? VDIMM? huh?

In order to change Ram timings and such, you need to get out of the Jumper Free config area and go to the chipset configuration, thats where all your ram adjustments are at, however your ram voltage is found int the Jumper Free config area.

Not to discredit you but I have found that you can force 400Mhz on the ram in the manual settings where you adjust the FS. I had a problem with the ram running a divider even when I changed the ram timings as you are saying to do and the only way I could get around that problem was to force the bios to run the ram at 400Mhz where you adjust the FS, that way I was at 1:1. This board could be different too. I am running the cheaper model so that may not be helpful but hope that helps.

Ok all I was saying is that if he wanted to change timings he had to go to a different part of the bios, in no way did I suggest to change anything, I was simply telling him where to find the rest of his ram adjustments. Also I know that you can change the speed of the ram in the Jumper free area but he has already found this on his own so I felt no need to explain this part. Anyways like you said the only way to keep the ram from running a divider is by ("forcing", or setting to manual) to run at the speed you want(timings will do nothing here). But like I said I, in no way, told him to adjust anything to stop it from doing a divider.

Thanks for the replies. Haven't messed with the timings in that section of the bios yet. I think I did see what you are referring to though, and MAY look into that later.
It's been suggested that 1.6v on the core is too high. I had read that as long as I stayed below 1.7v, there were no issues. Opinions? I certainly don't want to fry things by pushing it too high. Especially since per CPU-Z, I have a fair amount of voltage fluxuation as it is. I reduced the voltage this a.m. to 1.55, and I can watch it bounce from 1.535 to 1.552. Is that normal? Or is that an indication of a low quality PSU? It's also been suggested that perhaps it's "v-core droop" which many say ASUS boards are known for.
Thanks.
