overclocking 680io mb need expert advice, guide not avaible

The 500 series were horible OCer, the 600 series is essentially a 500 with good OC feature!

His guide still kinda apply to you, not exactly tweaked for you but anything in there is pretty much good for any platform.

I would give Wusy's guide a shot, any question/uncertainties
post in here we will help you

The next thread is for more hardcore/tweaking action but it applies to you tottaly.
Not exactly clear but pretty straight forward.

I just read some reviews to get some clues, you will have to fill in the blanks, and ramp it up slowly and test it but hopefully this helps.

This article notes that you have to adjust the fsb multiplier, just like ram multipliers so keep that in mind when you overclock.

not touching the unlinked mode, what exactly do i change and in what order. aka do i change the fsb number up and will it auto change the timing to 1-1 or do i change that first then up the fsb to 4x333

ok i think im suposed to change it from auto to linked, memory to 1-1 and fsb to 1332. can i change all three at the same time or should i change one or two first save and exit then redo.

speaking of timings.

im using cruicials tenth aniversery memory cas3 667 ddr2. the default was cas5 so i went in and changed it and now its running 3-3-3-12 np i notice theres a second group of numbers under memory timing and those are

trrd
trc 20?
twr
twtr
tref

im noticing the second number trc is at 20 is this correct, do i change the first four of htose numbers to match the first batch of timings aka 3-3-3-12 as well ?

Wtf i did the above and i get this looong as beeeep then i notice the settings didnt take effectn then i notice why.

with 1-1
and linked on.
it tried to run the memory at 1333?

holy potential fried memory batman!

wusy where are you!

nope left volts at 2.2 which is standard. btw the bios didnt like that setting so didnt actually implement my changes lol thank god. i notice it also didnt implement the voltage changes either, anyone know why.

when i changed the voltages i got a long beep too, and they didnt implement. i then adjusted the 1-1 and t hen restarted and did fsb.

perhaps the voltage thingy is a problem i mean if you up your cpu core but its not needing that much will it still alow you to set it to such.

I have a 680i with E6600 overclocked to 3400 and stable. I am running in the unlinked mode which my memory (Corsair DDR2 CM2X5400C4) and it seems perfectly happy.
I know I would have to go to at least DDR2 800 if it were in linked mode. Is there any particular reason why I should not be in unlinked mode?

wow wonder where wusy mad jack and the others are no other replys suprised, im kinda gunshy now on the whole oc thingy anyone got some definative results

ok well i went ahead and after reading some used the linked/sync mode. which gave it a true 1-1 memory ratio. i left the voltages unchanged and the motherboard as you can see from ntune auto upped the voltages for me.

so im at 3ghz, my temps fluctuate from no load aka windows 45c to running bf2 on high and at the same time a nwn2 server, and cpuz and ntune to a high of 48c. i have freezer pro 7 on there and my coolermaster stacker has 8 fans.

anyone see any problem with leaving it like this, aka the auto voltage and the syncmode/linked. yes i used the rest of wusys guide as far as disabling things and so forth but the only voltage i touched myself was the memory voltage as the cruical likes 2.2 per the book.

as you can see the auto voltage has cpu at 1.46 and fsb at 1.4 shall i leave it on auto voltage, anyone?

1.46 is too high for a 6600 at that speed. Mine is stable at 3.2 Ghz at ~1.39.

Great Post, in the process of reading it... should be of some interest!
