New i7-940XM ES installed

Quick question. Before I go about messing with throttlestop and whatnot.. I just cranked the chip to 5% in the bios and the cores are now going to 3.5 instead of 3.3.

Just a safe basic OC? Do I need to mess with the voltage?

Thanks
Helm

Ack.. should of posted this in the m17x forum... please move!

 

Oles chiefs the 5% stock bios OC is fine oles. No need to apply anything else to it. If you want to tinker more and stuff then you will need to set the Vcore to 150mv and use trottlestop as well.

Enjoy your new found POWER eheheh oles!
I want the 940XM oles. Do you have a link to the one you just bought? Thanks.

Cheers.

He'll go down to $520

Thanks for the info!

 

My 940 is also Shirley's.
What is your cpu temperature?

 

It's idling around 52. With furmark running it goes up to 76. I put this stuff on the chip.

Nice chiefs,

Thats some good stuff. Great thermal paste. I use that and Tuniq TX-4. Both provide great thermal conductivity.

Thanks for the link.

Cheers.

 

Furmark is for GPU
Prime is for CPU^^

Prime 95 pushed it up to 86. I'll mess around with it for a bit.

 

Don't forget to put your Wprime to 8 treads, it will stress it really hard, giving you a real idea of the highest temp you can encounter.

I may add that you should use Throttlestop, instead of your 5% OC, it can give you a real boost in multi-Cores/Treads applications without rising your FSB (so no ram overclock).

Cheers, and wonderful CPU !

 

And now to the question that every body want the answer to. Do you see any performance boost in games.. Big i hope if so , becuase im standing between building a gaming computor and il be selling this one.. Or, upgrading to a 920 or 940xm cpu. Whould be great if someone had, lets say a 720 and tested some games and installed a 920 and compared same games, tracks and settings just to see how many fps it boosts.. I realy would like to keep this beauty because it finaly works perfect.. But it seems that some games realy rely on higher clocks on the cpu to work as they should.

 

i'll say this. after using a qx9300 on the r1 (the extreme quad core) and using the 940xm..

there is virtually no difference in performance that i see.
if anything i think the r2 is slightly slower, but that's mostly on booting and what not, so different things can effect it.

i haven't been able to run games at any better of a speed/settings with the r2 than i was with the r1.

both laptops are in my sig.

 

I use to have the qx9300 version and the difference in boot time is huge if you have a ssd. the i7 version is also way quicker if you do video/music converting and editing. games like starcraft 2 will show some differences because CPU plays an important role.

 

I just got done with my i5 -> i7 940xm upgrade. Wow what a difference. Only did some benchmarks so far but I can't beleive the difference it made. That i5 CPU must of really been holding back my GPU's because of the way my GPU scores went up as well. I have not even touched any sort of CPU or GPU overclock yet either!

1st thing I should have done... magnetize my screwdriver. I dropped one of the tiny keyboard screws and had to tear it completely down again to find it. Not sure what I would have done if I didn't find it. Also I found a stripped screw on the metal plate above the left GPU, no idea how that happened because I hadn't even tightened it yet, maybe it was already that way from the factory. I was very careful with the outside because I didn't want any blemishes and I think I suceeded with that at least.

When I put it all back together the second time I was so worried that it wouldn't boot up, but so far so good. I just did a quick prime95 just to make sure the CPU temp wasn't high and everything seems good.

On the first boot windows had to find all the devices again and locate drivers etc, I didn't expect that to happen.

 

You might notice better scores in benchmarks but in the vast majority of games, you will not notice anything at all. Aside from GTA IV and maybe a few CPU intensive RTS titles or poorly optimised ports, I would be very surprised if you notice any differences between the i5 -> i7 940xm upgrade in real gaming performance.

 

i7 720 => 940 XM, huge difference in CPU dependent games like Wow, SC2...

Overall my P4G is more aggressive than before, boot time is shorter, even the alienhead boot screen shows itself less longer.

But I play mainly Wow so for me and my gaming experience (25 format raid with an heavy interface) it's a virtual-life changer.

 

I learned of few things taking apart my R1 and putting it back together a few times. Dont be in a rush!

WOW does seem snappier at 3.5 than 3.0!

Now if only my 5870's would ship from dell.... *sigh*

 

I have a 940xm installed (laptopmonkey) and my temps under load are 95-99 DegC with AS5

Ive ordered some Tuniq TX-4 so going to try that.

 

That (TX-4) is what I used. I didn’t like the way it spread, it stuck to the card really bad and I couldn’t keep it on the die. I ended up just mushing a little of it all over the die. I’m sure I put a little too much on, but I didn’t want to put too little. I tried warming it up a little but probably didn’t give it enough time. The funny thing is I was trying to get MX-4 that I’ve read about on the forums bit kept messing up ordering the wrong stuff.

I had some really old AS5 that I was afraid to use
I had the free stuff that came with my 940 cpu – did not even want to use
I bought some stuff off Newegg thinking it would be good enough
Then I bought some TX-3 off Newegg thinking it was the close enough to the MX-4 that I could not find.
Finally found TX-4 and then later realized it was supposed to be “MX-4” that I really wanted. Doh!

I haven't done too much testing, just a quick 5 min test with prime95 and it got up to 92 I think. I might have to redo it eventually but I will do some more testing to see if it's good enough for me or needs to be better.

 

I´ve got mine from him as well, I´ve been running Prime95 for an hour and temps are these (see image). I'm using Innovation Cooling Diamond

 

I agree with this. The games I care about (basically WoW and SC2) benefit tremendously from the 940XM. Even coming from a 820QM it is still like a whole new machine.

 

IC Diamond is the stuff. Thats what I perfer when I've quit benching and switching CPUs and just use the system for gaming and every day stuff.

 

Hello

Is my 940xm broken?

This is behavior the last 2 days.

Run Prime95
1-2 min Ca.

Is the CPU broken, pls help me.

Hi Guys,

First of all ... a VERY BIG THANK YOU to the community for all the tips, tutorials and tricks in this forum! It's been a wonderful source of information.

Now ... I need some advice.

I just completed upgrading my CPU to the 940XM "ES". I replaced the thermal paste and pads with some TX-4 thermal paste and Fujipoly Premium Thermal pads (1.5mm).

The job took about an hour and a half and the system booted first time, but, when I attempt to run HWiNFO32 I get a BSOD.

I haven't captured the details of the BSOD yet, but does anyone have an idea as to what might be causing this?

Just did that! It worked, Thanks.

 

I've seen that before too and I even tried to google "hwinfo clocks" to figure out what the clocks mean and how they work. I don't think your CPU is broken. Your temps are OK yet in those shots. In 5 minutes does it ever get above 100 or does it stabilize below that? You can try to see what Throttlestop says your clock is, and also CPU-Z. For mine HWinfo32 and CPU-Z say 3500 mhz, and Throttlestop is constantly fluctuating between 1700-3000 while sitting idle.

Do a wprime 32m test and see what your time is. I think about 13 seconds is normal for the 940xm. That will tell you that the CPU is computing at the right speed and number of cores.

***Just thought of something. Try changing your power scheme from "balanced" to "high performance" then see what your clocks show in HWinfo32. Press the windows key + "x" button for the shortcut to it. I bet they will show the max now.

 

The clock from
core0 91°C
core1 76°C
core2 95°C
core3 76°C

between core 2 and core 1 are 19°C difference.

 

Could be a bad paste job.Attached pic my temps after running Wprime on 1024M stability test without laptop cooler.That's with bios 5% oc & TDP/TDC @ 62watt

 

Oh I see now. I thought you meant the clock speed bars showing a low number. Looks like mine are usually withing 10 degrees of each other. Would those being further apart mean an uneven paste job, or maybe the heatsink has uneven pressure on the die?

 

thank you

I repaste the CPU and my max. temperatur in WPrime 1024M is

Core0 82°C
Core1 78°C
Core2 84°C
Core3 78°C

This is ok?

LG, Nafura

 

Nafura

That looks more than acceptable 100c TJ max before throttling so good job

 

good temps for M17x without cooler. did u raise the back of the laptop or is it really cold in scotland now? any tips to share?

 

Alex no special stuff going on got my M17x in my dinning room on a big glass dinning table .Room is warm don't know temp but i am wearing t/shirt right now.Just checked local ambient temp's min 9c max 13c.The power of MX-4

 

absolutely right, MX-4's the secret weapon.

 

If anyone is repasting the CPU, do yourself a favor and don't just tighten the four screws and button everything up.
This is from personal experience:
Leave the keyboard and power strip open so you still have access to the four screws holding the CPU heatsink. Start the computer up like you normally would. After the computer is fully loaded, start you favorite CPU testing and temperature monitoring program up. I use Everest Ultimate while others use Prime 95. Everest Ultimate heats my CPU faster and higher than Prime 95 running 8 ever could for me. After a few minutes, the temperature should stabalize out (not max yet) but you can see the difference between the cores. If you want, let it run for at least 15 minutes before attempting the next step.
Now, use a screw driver and readjust the four screws holding the CPU heat sink. Do a very small amount of turning at a time and give the program monitoring the temperature to catch up. You may have to tighten some while loosen some with others. What you want is to have all four cores temperatures as close to each other as possible. Tighten/loosen the screws until you achieved optimum temperature (by that I mean if anymore adjusting will only yield higher temperature).
I have 940 XM and all four cores are between 74 and 77 after an hour of Prime 95 (trying to use same program as most people do).

I am not trying to tell anyone what to do as I am no expert at this matter. Just passing on my experience.

 

ils - Great advice! +1 That is definately a trick that works and that I do myself as well.

 

dont really work for me. are u doing retention mod? because according to joker, this method will only work if retention mod is in place.

 

Just completed my 3rd re-paste on my 940XM "ES" and I'm gradually lowering temps. Not using the retention mod and only some TX-4 and new thermal pads, I've managed a maximum of 84 degrees Celsius running Prime95 for 15 minutes running both small and large FFTs.

I'm not keen on trying the retention mod. Can't afford to crack the CPU and/or MB.

I might try some MX-4 or IC Diamond next.

Saving for an SSD now.

 

I am not doing any kind of mod. Just AS5 and a little patience.
Bios is OC with 5% and the back is raised about half an inch. Ambient temperature is ~ 72 F. And as I mentioned earlier, my 940 XM is running between 74 and 77 among all four cores. The chip is from DELL.
