well i finally have the cooler and time to spend figuring out overclocking.

system:
asus a8n-sli
opteron 170 lcbqe
2x 1gb mushkin cheap stuff running at 2t i think...will have to finish testing this fresh rma ram.
seasonic psu


so are my pci and pcie slots locked? i can just go ahead and start playing with fsb settings to isolate and consolidate?

does it make sense to use clockgen just to see a relatively safe oc? then i won't have to go in 10mhz increments...that would take forever!

It isn't just adjusting the FSB bus speed to the CPU. When you up the bus speed, you also turn up the speed of the memory. That is why most decent overclocking boards have multipliers for running your memory at a different divider. On my current board, this is numbers like 2, 2.5, 3 etc. On some boards, it bus speed numbers like 100, 133, 166, 200. The trick is to up the bus speed of the CPU, thus increasing the speed of the CPU, while at the same time keeping the bus speed of the memory as close to stock as possible. So you end up only overclocking the CPU and not the memory.

yes. for the most part, i understand the concept of overclocking. i created this thread because i don't know the specifics. like: what timings are safe to play with? 2x1gb mushkin sp3200 991130. if 1t is stable, should i go ahead and keep it at 1t but relax timings?

Yes, that Mushkin will run at 1T easy. If you are going to use a divider then set voltage at 2.8 for the memory and start it at 3-3-3-8 or just run it on Auto. I'm running 2.66ghz at 1.38v so you shouldn't worry about having to stick a lot of voltage to this chip. You'll want to set your HTT multiplier down on 4. A 4/5 divider should give you 2.5ghz to start.
