im new to overclocking and i want to experiment overclocking my computer. i have a asus a8n sli premium motherboard, amd athlon 64 3500+ venice processor, 2gb simpletech ram 3-3-3-8, and acpi bios revision 1009. i also installed aibooster v2.00.68 for the CPU tuning i can set the external frequency and multiplier up or down, for the voltage i can set the cpu and memory up or down. i tried setting it to 240 external frequency and 10x multiplier, i left the cpu and memory voltages at default click apply and my computer froze. now im not sure if im doing it correctly or not so any help would be appreciated thanks.

Uninstall AIBooster. Overclock manually thru the BIOS, not thru software.

CPU Freq = 250MHz
CPU multi = 11x
HT multi = 4x
PCI-e = 100MHz
PCI = 33MHz
RAM = DDR333
Spread Spectrum = disabled
Cool 'n Quiet = disabled
RAM timings = 2.5-3-3-7

- increase CPU voltage only if necessary to stabilize the overclock

Results: CPU at 2.75GHz, RAM at 208MHz, HT bus at 1000MHz.

Adding to the above....

Depending on how overclock-friendly & the speed rating of your RAM, you may be able to run your overclock synchronously -- 1:1 -- by setting the RAM at DDR400. Also you should try 1T command rate for the RAM unless you can't get a stable overclock with that setting.

A minor correction to my post....

With the settings I provided, your RAM may run at approx 197MHz instead of 208MHz. It depends on the CPU multi setting. A small program called 'A64 MemFreq 1.1' will help you to sort things out. You can find it, along with several other good tools, here:

what do you mean by 1T command rate for my RAM?.

The Command Rate setting helps with maximum theoretical memory bandwidth. It's the time needed between when a chip is selected & when commands can be issued to the selected chip. You have the option to set this at 1T or 2T (slower clock). Check your BIOS for the setting & as I said before if your RAM can do 1T without any problems, then go for 1T.

SDRAM Command Rate

Don't mean to hijack his thread, but I was reading about the command rate thing. Just curious about something.

I have 768 or so DDR SDRAM total, a 256 Samsung pc2700 and a 512 Micron pc2700. I was looking on my BIOS and it had the command rate thing, and I set it to 1T and my system seems to be running alright. Should I keep it like it is since it seems to be stable?

Again, sorry for hijacking the thread, I just figured since this was what everyone was talking about, it'd be better to ask on here than start a whole new thread.
