A8N-SLI/General Overclocking question

So I'm pretty new at overclocking (mainly doing things I know my hardware can handle/keeping a close eye on temps). But I have a few questions... First off, my setup:

Athlon 64 3200+ 90nm
A8N-SLI Deluxe
Kingston HyperX PC3200 (2x512)
nVidia 6600GT

Now for the questions. Concerning memory, in the bios I can set the MAX setting for the ram by choosing from a list (DDR266, DDR333, DDR400 etc). Now I know this translates to 133 166 200 and such. Now, if I leave this on AUTO configuration, and raise the HTT from 200 to lets say, 220, that in turn raises my memory to that speed as well correct?

Now lets say I set the MAX ram speed to DDR400 and tighten the timings at that speed, then raise the HTT to 220, does that mean my ram will not surpass DDR400 speeds, while my cpu speed will increase?

Also, does AMD Cool 'n Quiet technology hinder overclocking ability? Just raising my HTT to 220 with it on I get the "CPU failed due to overclocking" message.

Another question.. how do the HTT, HT multiplier, and RAM speeds all relate, if they do at all?

Thanks in advance.

Check this thread, this should answer some of your questions. The first few post are extremely helpful. From there we kind of drift on and off subject. Newbie Overclocking

Your first question regarding auto memory setting. Your memory won't raise to match you cpu overclock it will change the memory timing so your DDR400 will not go above the 200mhz that is rated.

Cool n Quite.. I did few load test to see how this would react. With the CnQ enabled the cpu heated up quiker but still maintained its peak temperature.


My experience. I managed to get my memory speed to DDR466 and left the overcock to auto. After booting I use AI to step up the overclock. After setting everything in AI it will retain all the settings even though it still set to auto in the bios. The only item of concern is the voltage. I have to set voltage each time I boot with AI. The bios keeps maxing the voltage during post.

Just pay close attention to GuitarDaddy"s post in the link above. Good Luck

AUTO = automatic memory divider that kicks in at 217 and keeps ram at 200 or less
DD400 = 1:1 Ram speed = HTT as you increase HTT ram speed increases (this board tops at 240, this setting won't work with HTT over 240)
DDR333 = 6:5 divider 288HTT = 240RAM
DDR266 = 3:2 divider 300HTT = 200RAM

HTT x HTT multi = FSB ie 200x5=1000FSB (as you raise HTT, lower HTT mutlti keeping FSB < 1100)
