I have the following setup below. I want to overclock this baby to basically as much as I SAFELY can, but I don't know what all the voltages for the core, dram, etc. should be.. and I also don't know what multipliers and fsb speeds to use...?

Along with that I don't know what timings I shuold use on my memory.. so if some people can post their overclocking settings for me with the same exact setup or close to it, I would appreciate it. I don't want to go changing my voltages and timings and burn something up.. lol

Please see my profile below for all my system info..

You'll want better cooling before you overclock. You should be able to get to around 250MHz bus with a core voltage of 1.65v, if you can cool it enough. Give or take 10MHz bus...

Now, 250/200 would work with the 5:4 ratio. At having the memory operating at PC3200 speed like that would probably allow slightly faster timings.

what is the math equation that you use to figure out 5:4 and 3:2 ratios? I am not very good in math.. lol

So if for instance I wanted to figure out what the ram speed would be in a 5:4 ratio if I knew that maybe I wanted to take my FSB up to like 271mhz ... how would I figure this out with math equation?

My new case and cooling should be in by the end of this week.. I got the Thermaltake Xaser III with the Vantec Tornado 92mm fan... it's going to be LOUD, but cool..

5:4 CPU:RAM at 271MHz CPU bus...271/5*4=216MHz.

<font color=blue>Watts mean squat if you don't have quality!</font color=blue>

would this 271fsb 5:4 ratio be faster or would it be faster using the 1:1 ratio and keeping the FSB at 216mhz?
This is without chaging the stock Ram voltages or timings right?

What do you think the max fsb speed, the max voltages, and the max timings my HyperX pc3500 could handle? I have 2 x 512 modules by the way running in Dual Channel?
I don't want to blow them up you know..

Although your memory performance would surely suffer a small amount, your CPU performance would be increased by so high an amount that it would more than make up the difference.

The PC3500 modules you are using are rated at very long Cas Latency cycles in order to assure they work at the advertised 218MHz. Using smaller Cas Latency settings increases performance but can cause stability problems. It's probably better to use your modules at 200MHz and Cas 2-3-2-6, than to use it at 216MHz Cas 3-3-3-8, because of the faster response time. That is, as long as it's stable.

Hey Crashman.. I know that you know your stuff.. check out my thread on the Abit boards.. my name is Squale.. look at the timings and benchmarks that I am getting and comment on what you think thus far.. I have oc'ed anything yet..

I think it's time someone figured out how to make modules that support lower latencies...

<font color=blue>Watts mean squat if you don't have quality!</font color=blue>

you think it's the latencies that are holding me back from the f1 GAT settings?

What do you think the F1 sets your Ram timings to when you enable it?
