which elite u refer to...
well, everybody is learning and share comments in forum. mayb everyone else realise the importance of GTL when new 45nm proc comeout while old chipset board default GTL values are meant for 65nm. I also in the learning process, just realise every proc are diff reference values i guess and if want to get precise GTL we really need a DMM as cstkl1 mentioned. Till nw i also not sure whether my gtl ref values are correct, but as long as its stable at my desired clockspeed + a bit lowerr vcore than w/o tuning i am happy with it...

agreed...learning is a process rite...everyone also a noob before...

lol..me no elite..me noob..wanna learn wats gtl...isit related to my oc stability?

Anyone have any links to any guides regarding GTL for quads?? I onli found references that are very general....

U r the man!!! Thx for the link.... But after reading a couple of times, I can't seem to understand.... Maybe I'll ask u in MSN...

New Intel P45 OC mobo in town : J & W P45D2-Ultra

@1st i thought its a P4 mobo by looking at the box from far

Wah, Raymond, you really buy it ar?

cryptik .. sish..

wrote that formula in the maximus 2 thread like a few months ago...

but he still doesnt get it..... gtl is just fine tuning for the vNB..
the main reason is this.. when u ure multiplier and bus to a certain vcore...
the previous FSB voltage NB voltage that works for the previous bus wont work..
reason is look at the gtl graph in www.edgeofstability.com

example for 533fsb i needed 1.16vtt, 1.32vnb gtl 0.63.. but its good up to 4.25ghz at 1.32v vcore..
because of the fact 4.5ghz i need more vcore the previous vtt voltage / vnb wont work..
even if i pum to 1.7v on vcore it wont work..i mean it will boot but wont pass any stress test to the cpu...

this is where gtl really comes in play..
its to maintain the same ratios or support resistance level ( hahahaha.. cant beleive i am actually using this word in overclocking) but the same GTL values..

i hope this explains a bit.

same thing for quads who require high vcore but not really high vNB.

cryptik wrote wrongly and took it out of text..
i wrote that just for one guy system.. not a general rule..and he is making a lot of general rules..
dont want u guys to fall into that.

another example which all of u i think must have not realize something..
previously when u ran orthos at a certain vcore for high mHZ speed u suddenly hit a brickwall that the vcore needs to be raised exponentially.
1.so ure answer is the proc scales well to that vcore... or 2. the most commonly answer is ure proc is too hot.. ( but already disapproved when u ran linpack to 80C.. )

what if i was to tell u its not that..
this is where vid numbers really come into play...
low vid procs has neeeds lower vcore to run.. but because of this it wont suffer easily like the above issue with vNB and vFSB.
but when u look at the speed to speed of a higher vid.. the heat output for both proc and different vcore is same.
but the difference is to go higher mhz he doesnt have to tax the mobo a lot or adjust a lot..

this is the difference..
and worst still each mobo i/o.. crossovers are different etc...
so yes for a certain speed its acheivable on all the mobos but for higher speed stability.. some mobo out there might suprise u
but it only might work for ure proc.. not a general rule to all procs..

anyone wanna help me? running e8200 c0 3.8ghz on 1.48v..i tinks its a bad batch..wat u ppl think? can boot at 4ghz at 1.56v but still failed ibt....usinog tpower

any more bios settings?

good explanation there, cstkl1

Good explanation but quite technical
Even bryan explain in layman term,I also can't understand

wah...no ppl help me ar?

wah..bryan sure good...come..tell me oso lar

I'm getting more confused as I continue to read on all the references I found..... Now I also wanna pengsan la....

@cstkl1: I roughly get wat u mean but I just dunno how to calculate the values and to determine how much voltage and GTL i need to set in order to run at a certain speed.....

dude... that thing that i posted and also crptik was only for asus mobos..

its the same with the striker 2 formula/maximus 2 formula/rampage extreme/striker 2 extreme..

but in the end for more accuracy use a vmm..
again gtl i only needed example for quadcores at high vcores
or dual cores at high mhz with high vcores...

when i say high i mean like 1.4v example depending on ure nb voltages to ure fsb voltages ratio..

thats when it really comes into play...

ure xfx 780 board.. god knows why u bought that board... works differently...and doesnt clock that well ..

Okok.... If I were to give u the settings that I'm on now, will u be able to give me an approximate setting??? Then from there at least I can tweak it and be able to understand more.... The onli thing I dun understand is how to get those calculations and how to set the appropriate voltages if GTL is applied.... I bought the XFX one coz I heard quite a lot of good reviews about it and it costs lesser..... If I got the chance to try out ASUS, I will try also but at the mean time I'll be sticking with this one...... I just need to get the right theory then no matter wat board I use next time, I will at least be able to tweak it as it is intended to be....

lol..pening pening..duno wat u ppl talking bout..haha

Wah, a bit hard to understand this gtl thingy

well all i can tell u guys

get a good mobo with a lot of good voltage adjustment features..

aka rog's... dfi's
get a VMM ..
test and document.... and u will understand ...

sorry dudes no shortcut on this..
hmm i wonder with i7 having a integrated mem controller.. gtl shouldnt be a factor anymore...

wonder wats i7 price like when its out...
