throttlestop setting advise

hi guys just replaced my 740qm with a 920xm
the 1st thing in my mind is overclock!!!
seen so much abt u guys's super pi 1m's benchmarks makes me so jelly~~
but i dun know maybe im dun have sucha luck to have a gd 920 or maybe i just dun know how to set the program

currently the tdp and tdc were 90/90
the TRL is all set to 25
i've tried 26,its not stable
just wondering how u guys tweak it
also i've tried the set multiplier options
but it never let me adjust to above 15
need sum help here~thX
PS:is it possible to run dailies with all 27?

 

For Set Multiplier, once it hits 15, click once more and it will go to Turbo. That's what you want. It means it will prevent or resist throttling via forced multi reduction below the multipliers set via the TRL table.

Settings of 26x across the board are often difficult depending on temps, load and total power demand. When conditions are right, most 920xm's can handle 26x, but at other times under different conditions, they can't. CPU's differ, and you have to feel your way to the limits of your particular chip by trial and error. However, a 920xm at 25x or 26-26-25-25 is a beast. Enjoy your new toy.

 

thx for the advice
i think the temp wouldnt be a problem since its still below 80 even if it is 100%full loading
power draw r at 85W
when i try 1024m it saids 1error
then i stop it and try to adjust the tdc to give more power
but still got errors,after 2more fail, BSOD 3b comes out
mostly are bsod 124 sum times 1e
this's the info i got
if even 26x is sucha pain to me maybe 27 is impossible?:'(

 

Do you have an OEM or ES chip? IF ES, which stepping?

I haven't seen a 920xm so far which was able to handle 27x on all cores without adjusting the voltage, only 940xm.
With a pinmod I managed 31x stable on all cores, but it gets HOT.

 

its an es,stepping=Q3B8
im interested on adding voltage,but how?
wt do u mean pinmod?
like the old days we use pencil on the chip to connect some places ?
hm....i just checked your post abt the voltage increase
i saw that when u running all cores on 30x
its still below 80c,wt cooling methor r u using
in my case i will go up to 87c if all cores r on 100% even its only at 25x
the compounds im using is liquid metal pad,i heard its 2c below as5
but why am i still going that hot
also,can u share the settings with set fsb or throttlestop?
i tot only throttlestop will be fine
thx

 

That's the same stepping I have, there's nothing wrong with it.
My voltage mod was mainly for benching purposes, and to see what the chip is capable of. Some pics and details can be found here, you will see that this method won't increase the voltage for all clock speeds, and running the CPU at 30x or above is nothing for daily use, too hot and an insane power draw.
But you could theoretically modify the voltage regulator to increase the voltage very slightly for all VIDs and this would allow you to run it at 27x, but it'd include some soldering on the mobo.

You have to see that 25x on all cores is already a great overclock and every 920xm will run hot at this speed when there's 100% load for a sustained period.

I don't use setfsb, unless for benching purposes. My 920xm becomes unstable when I use setfsb (unless I add some voltage). I recommend only going with the multiplicator for overclocking this chip, less trouble and very stable.

I use a lot of different settings for TS, depending on the application. I have a 6990m and therefore need to keep a good balance between the CPU and GPU settings.
When I had the 5850m I used most of the time 27x,26x,25x,24x at 85W, gave me a very good performance and heat balance.

 

thx for the advice...feel like i can always learn from u
sad that i dun have a good stable hand to do soldering work
