Heh, well actually although I have started doing a manual overclock, I still am relying on a few auto settings here and there... In that sense, this biostar mobo is very nice.
(though I WILL get a screenie of the memory tab of CPUZ uploaded in a moment)
As with most shortcuts though, I understand that there's a good chance it's not the best route to take. My thoughts behind it was I could set everything else up and leave memory divider and timings on auto (memory is the one area I don't fully understand yet). From there I can find FSB and multipier settings that work effectively, then go back and test to see which memory dividers work best with the other settings I cherry picked myself.
What I currently understand about overclocking is the following:
is the main variable in the formula, which I symbolically see as "x
" (like in a "mx + b
" formula, where b should equal 0).
is the "m
" and the solution to the formula is my predicted clock speed in MHz.
" in a second formula, and "mx" should be <=1000 (can be a little higher, though there's no point. also, now I understand why you said a HTT multi of 2x is fairly unideal in most scenarios, joe
. I'd quote the post, but that had to be a year ago)
(to me) is something you lower to make your overclock work
. I understand it's affected by the FSB (everything is), though I am unsure of what kind of formula to use to figure out what need. IF I am understanding it correctly, if you take DDRx
and do x
/2, you (ROUGHLY) get the stock FSB of the motherboard you're using. So since I'm using DDR400, that would be 200MHz which is the default of both the 939 motherboards I own.
With that said, if I increase my FSB to 216, wouldn't that mean my RAM is running at DDR433? (using the formula I pictured, it would technically be 432, but I assume I would round up). If I'm toying with my overclock and memory dividers, am I trying to find a sweet spot (and rounding down when necessary)?
The main thing I want to know is how much over the stock ram speed in MHz (effective FSB) is typically okay to push. I'm getting the idea that my ram chokes a little if I push it past DDR433 without changing the divider, as 216 used to be the highest point i'd see stability at (...at least, before i came across OCN
). It's also highly possible I answered my own question from above without fully realizing it.
I'll leave that to the most of my questions for the time being and work on understanding memory timings next. But hopefully someone else will benefit from my mathematical approach and basic questions associated as well.
In the meantime I'll be trying what you suggested Joe, and then if need be, i think I may WRASTLE with some memory timings and information too.
EDIT: @blitz: Ouch! Sorry to hear about the traffic stuff, but no worries on my end on roster updates. Hope tomorrow works out better, traffic wise. Also, you reminded me of this track
, so if you happen to be an electronica fan at all, enjoy. Edited by timxirish - 7/10/09 at 4:08pm
