M17XR2 Overclocking Guide

What would be a good setup as far as multipliers and voltages that would get me the same 3.5Ghz in Throttlestop as with the 5% OC from the BIOS?

 

26x133 = 3458 or 27x133 = 3591

but my guess is that either of them will require at least +75mV, probably even 150mV for near 3.6Ghz

I won't consider either of the 2 above setup for a daily use, or anything that need overvolt

 

most of the time i dont do anything because the stock 3.2 ghz of my 920xm
is already a monster and i dont need to because max what i can reach is 25*133=3,33Ghz without volt increase i just need th.stop@105/83
the systems making problems when i want to go further than 3,33Ghz
i guess its because of heat issues.
in normal life and in gaming you wont notice the difference between the stock 3,2 and the highly oc'ed 3,5 because there are no cpu limit in games!!maybe in 2 years we can talk about that stuff.
i would recommend to buy an 920/940xm ES put it in your allmighty and love it thats all.

 

Edit: made a new thread

 

sorry,

someone merged my post in here, it was a question specifically for i7 940 xm cpu owners.

question deleted.

 

wich was the question you had?

Lately i've seen moderators merging threads too easily imo... without realizing that too often merged threads doesn't get any attention nor answer..

 

imo you are 100% correct

 

I haven't Overclocked my system in a while, so i tried out this guide. I put the multipliers to 27x and used the bios for the 5% boost and added the tdp boost to 85/70. My fans are constantly swapping between really loud and loud. And to top that off in HWinfo64 the cores show up as red. You guys know what is wrong?

 

Holy Shiatzu , 3,8Ghz! i think even HWInfo says you should not be doing this hahaha

btw.....are all the 920 and 940 users using a OEM QS or ES CPU's?

 

Im considering getting a new processor for the r2, is a big difference between 920 and 940?

 

No, just consider the price difference and there is non.
OC the 920XM and you have 940 XM ( i think they OC to the same freq. anyway)

 

Im using 940 QS. Can do 5% and no voltage increase playing black ops 2 or running vantage etc using computer for hours.
Will run at > 3500 per core.

Have also experimented with trottlestop to run at 28x with the 5%, that makes it a bit unstable.
At 30 it will almost always bluescreen me.

 

5% from unlocked Bios or....?

 

from unlocked BIOS yes.

 

Guys yesterday i finished setting up throttlestop with mu m17 r2 and my 920xm

For everyday use I have it at 27x/26x/25x/24x . Full stable with no extra volts and 90C max

Also I use 2 x 5870 crossfire

I setup 3 profiles in throttlestop one with the multies I told you one with rurbo boost of 15x multi and one for battery at 9x multi

So I made a test . I run hawken and bf3 and tried switching the throttlestop profiles with the hotkeys ingame.
I found out that whether at 25x multi or just 15x there was no difference in game fps. So the games ate not cpu bound-throttled. Next week I will install my 7970m so I will check with it too. If even with it the games are not cpu bound then it means that our r2s with 920xm or 940xm will hold their own for several years to come.

 

What you say does not make sense. Throttle stop will use your lowest multiplier (just start the ts benchmark and see for yourself)

You are oc'ing with a multiplier of x24

Using more the 2 profiles is lost to me.
Power consumption on a R2 is always high. If you unplug it tou cant game on it because it will throttle almost at the beginning.
Your battery can deliver i think, 90watts your cpu alone (oc'ed) will consume more the your battery can supply...i am not even talking about the screen and gpu(s) power consumption... So gaming on battery powered R2 is not done.

All your power saving will safe you 10 minutes of battery life... Why would you want to do that anyway... Total battery life could be 1,5 hours max....the R2 uses the battery mode to finish up work, should your ac adapter fail or something.

So you basicly oc x24 or use battery settings... Get it

 

You are right about battery. I just made the 3rd battery profile in throttlestop to keep the CPU max at 1.1 ghz , this combined with all power settings to low ( brightness , led lights shut down) managed to keep the r2 running on battery surfing the web for 1:37 mins

That was better than the 1 hour 15 mins I get without throttlestop battery profile
Ps. I never game on battery, I just want to be able to surf the net for 1-2 hours with that beast,
Gaming on battery is not recommended or practical :thumbsup:


Battery profile aside , I made the other 2 profiles in throttlestop to either push 4 cores at 24x multi or lock them at 15x multi and see if that makes any difference in gaming. And with 5870cf it doesn't. So the bottleneck are the gpus. And because these cards in cf are the same as a single 6970 then if you have one again the CPU is not the bottleneck.

That's why I will test my new 7970 next week to see when handicapping the CPU at 2ghz or letting it run full at 3,3 will change anything in game. If not then even the 7970is not enough to overshadow a 920xm or 940xm

I don't know about 7970m cf or 8970m

 

You better read up on the XM cpu's and 7970m in CF or 680m in SLI.....you will see that it won't work as you will expect it too.....you will reach the peak of 240W when you are not even oc'ing...

 

i know the problems with cf or sli, thats why i am going to get only one 7970. And after 3 years hopefully i will again buy only a single 9970 or a 980gtx, because (i hope) they will be mxm3 and 100w cards. So they will work flawlessly with my oced 920xm without any power sortage.

as you know the sli and cf problems are said to be power ones. the 240w brick cant keep up with them

PS. Please could you clarify the throttlestop setting of TPL , in which you give TDP and TDC limits? i mean i understand that you tell the program how much you want the cpu to be able to use from power BUT when the cpu reaches these limits what does throttlestop do?

 

I think you better ask this question to Unclewebb, He designed it

 

has anyone been able to overclock a 920xm to a stable 3.5 Ghz? im having problems getting it stable. even with the .15v increase in the bios and 5% increase in speed, i cant get my cpu to be stable at 3.4ghz. it doesnt give me a bsod error as well. it just restarts on its own. im using throttlestop with 25x multiplier on all 4 cores and 100 tdp and 100 tdc. anyone know what im doing wrong?

 

You havent read this thread have you.
Common knowledge that you just use the multiplier and don't touch the BIOS 1~5% settings.
You can use the increase mvolts.
The rest i will leave for you to use the search feature.
Many OC settings have been poster over and over. Many OC settings have been posted over and over.
x26 is the max ever achieved with stock cooling to run stable ingame. Good luck

 

ive been playing alot more with my cpu and so far i have hit 3.7ghz on all 4 cores while running hitman absolution benchmark. when i try to use the benchmark on throttlestop, it throttles my cpu to 3.4ghz as soon as the benchmark starts. while testing i had a hardware failure, nmi_hardware_failure, bsod. since then, i increased the voltage in the bios. i did not change anything else other than the cpu voltage. so far, no bsod and temps are in the high 70s to low 80s. to wrap it all up, the only time i hit a wall is during synthetic benchmarks. in games, it performs well.

 

Real world gaming does not push your cores 100% all the time. Synthics benchmarks however will push 100% and this is why more then one benchmark must be used to prove stability.
Having XM cores reach 90~100 degrees C is normal.

 

For me BF4 makes my CPU work really hard.

Settings giving me extreme results in benchmark is unusable for playing BF4 over time.
Can easilt hit 100 deg if i try more than 95/95 TDP/TDC.
I can go way higher during benchmark of course not counting 1024 test for T-stop.
