940xm or 920xm question

I have a question about these processors. They can be oc normally without using setfsb. Has anyone OC their 920xm or 940xm? If so, what kind of temperatures have you gotten and whats your thermal paste?

 

i think u can OC in BIOS... with throttlestop , u can lock 8 threads at 3GHz and above.. that's why 920xm and 940xm are awesome.. i think u can OC them in BIOS but throttlestop is best. .. don't about temps but should be normal.

 

Installed a 940XM two days ago, so i have just started fiddling around with it. At the moment the Turboboost multipliers is set at 28,28,23,19. Multiply by 133MHz to get the frequency for 1 - 4 cores usage. After a couple of 1024M runs in wPrime the temp tops out at 80C. Thermal paste is ICD7.

 

try throttlestop.. its maker is on the forum.. he's tested it with running i7-920xm and 940xm locked a 3.3GHz on 8 threads.. totallu unleashes power of i7 CPU's...

 

Running all four cores under full load at 3.3GHz generates massive heat and needs a lot of power. To reach those speeds without additional cooling is not going to happen. The 720QM has a TDP of 45W, the 940XM is 55W. Currently, mine is stable at 78W without additional cooling at 25C room temperature. In my opinion, that's pretty impressive. My goal is to have my G73 running completely stable for hours on full load without the CPU throttling down due to heat. I am not interested in running quick benchmarks with highest possible result. I want a stable system that is going to last for a couple of years.

 

wait, so your saying you are getting 4.6ghz on 4 cores? and your temps are only at 80c?

thats insane!! or did I do the math wrong? I have to be wrong since i think that isn't possible

isn't the 19 4 cores, so 133.33 x 19 + 2133?

 

Oh no, at 4.6Ghz it would probably melt or explode.
To clarify my somewhat fast and fuzzy answer. The TurboBoost feature changes the multiplier depending on how many cores being used.

1 or 2 cores, multiplier is 28, 133Mhz x 28 = 3724MHz
3 cores, multiplier is 23, 133Mhz x 23 = 3059MHz
All 4 cores running at 133 x 19 = 2527MHz

Cheers

 

maybe several decades from now, we will have notebooks that can reach 5ghz quad xD I predict that we will see something like 1.60ghz with 24 threads. wouldn't that be something.

thanks for clarifying that up.
