furmark is potential GPU killer tool, why would you use that... crazy ;D

 

not in my case that's rumor repeated by ppl that don't know anything about own laptops/pc

mounted case panel , around half hour in gta4 max temp 85C of course on 26x
very nice but loud :/

 

Ok I wish you all the best with that theory

your temps are very good, take in account its winter and its colder than any other seazon of the year lets hope it will stay same great in temps during summer too. I got to admit temps are impressive! BIG IMPROVEMENT

 

mostly blocking gpu heatsinks helps create more air on cpu heatsinks side for sure
and yes temperature now is lower than in summer but from non-possible 26x i can run it with case closed
later need to drill more holes also to be more safer with air condition

 

good idea as long as both stay within good temperatures

now I got to say your 920xm is about as fast as my 2670qm haha very impressive

 

back back back


no acces panel
no fan plate
no blocking of gpu heatsinks
asus fan that i show few days ago but with cable soldered [yes it's possible] to have 3wire with regulations [on 2 works with regulations but stop and runs] - now it's works like should be
almost 8cm wide - nothing bigger we can put inside and even if he blows to keyboard that to heatsinks directions it's works beautifully for what i testing
thats not 100% speed

 

Now it's time to slap a 7970M in there after all that cooling work!

 

Hi Guy's, After a very successful upgrade to the 7970m thanks to the good folks on here ... I am selling my 5870 with un touched 2 pipe heatsink. Thought i would post here before ebay.

 

that would be beneficial buy for someone building barebone laptop etc, but you need to post that in FOR SALE forum and not here.

 

Ahh ok sorry didnt know ultra. Apologies.

 

No problem savier

so went tinker little bit with my unlocked bios settings and made it to last longer on turbo boost, also managed raise secondary power limit to 72W

here are my TS bench and Wprime209 best scores I could achieve, with temps showed on i7-2670QM



comment what do you think?

@ Savier1

did you get that 180w Targus PSU I linked you to?

 

No, they sent a replacenet for my faulty one so didnt bother. It works s treat.

 

sure thing as long as it works and makes no sound

what brand was the faulty one? or was it just "replacement charger" brand?

 

Hello people

I kinda miss my GX660 since I gave it to my friend and moved to a GT780DX
Now he's asking me some questions. Since I'm upgrading to a 7970m he wants to get my GTX570m.
Question is does it work on his GX660 ?
Anyone tried upgrading?

Thanks in advance

 

Yea It will work, only Nvidia GTX 680m (and the remaining kepler based cards may not work)

 

looks like 920xm is to weak :/

 

its nooo way to weak man, youre just mere few seconds behind in all tests, 920XM is great cpu that can even up to sandybridge and if cooling allows can compete in higher speeds

I was soo disapointed in ivy bridge in my m18x r2 with 3610qm that wasnt anywhere far from my 940XM cpu in TS and wprime I started regretting I sold my baby

So ran today some quick tests with new 2860QM OEM CPU and here are the results:

 

little update
cpu heatsink polished but still get 10C differencie between cores [or even near 20C with hardcore prime95 test] with only 23x
problem is in the CPU core - it;s crooked in any way then only 2 inside cores are almost 100% touch copper and both outside cores aren't really touch the heatsinks

need manual polishing - maybe i can do this 100% similar to cpu crooked core some day but it's harder than polishing to flat/curve plate
for that 2inside cores i get good temperature for 23C [or even really good around 80-85C for what i measure under prime ] bot rest ...

looks like polishing helps drop temperature for real - ofcourse especially for inside cores

and if someone interested all quad cores must be curve surface to protects the edges of core

@UltraGSM
don't kill my [and other] xM cpu
you buy 7970m maybe now ?

 

Yea waiting now for my 7970 delivery maybe next weekend... but need to find some extra time installing that one as I will be shaving off the entire NVIDIA heatsink and not buying AMD heatsink for mod fit 7970 this time.

Sorry didn't mean to defame the 1st gen i7 XM cpu's but at the same hand you can now see how close 920XM is to sandybridge i7 I had first 2670QM and now 2860QM is of course nice bit quicker than 2670qm but I cant sense major effect over the 2670qm just yet.

So if you have i7 920xm 940xm - IT IS MORE THAN ENOUGH FOR WHATEVER YOU DO (gaming etc) unless it goes to media editing that requires CPU then its out of question you'd probably want go desktop then


I have also bought backlit GT60 GT70 steelseries keyboard to fit this GT683R and will make backlight work too at any cost

 

man the 2670qm should be [in my point of view of course] close to 920xm with for example 26x multipler but that's different side or can i say the same performance - but only the same not better for XM that i paid a lot of money
the main problem is XM need a lot of more wattage, heat dissipation and SB can do the same with default cooling system mounted in MSI - that's is brutal
but yes - i get real [or somee games any ] performance jump

why you don't get alienware ? man is much quieter , much better even with one card ? you don't like quiet laptops ?
im now running on default fan because i can put in 23% of speed and i had quiet - i can hear hdd or electronics when cpu works

desktops - not if i not really need to work or something

 

I had two M18X R2 in last 3 months, there too overpriced to what it comes at the end of the day and yet probably the only AW I would like to own. Sure I would prefer one but it will sound like cr@p on the speakers compared to MSI Dynaudio, screen is fitted in deep clear plastic moulding box that works like a real mirror(imagine double glossy LCD), kinda didn't liked that so much but could have lived with it. Crosfire of 7970XM was somewhat ~40% + over single 7970m as I have compared, not extra at least 80% as Id Imagined and yet these laptops are still not well made, couldn't use my SSDs in RAID0 because of manufacturing flaws in HDD ribbon connector cable, 1866MHz RAM wouldn't work on random machines and etc, keyboard not the best as its old type backlit only, not even chicklet, the rest like ports layout and variety and features and CPU GPU capability options and magnesium aluminium casing is amazing stuff but I want stuff to work 200% perfect first time, and AW aint doing that for me yet, so I have pulled back for some time till maybe new M18X R3 is out but I will be keeping my MSI to have it to compare haha.

Plus I love add some of my own signature to hardware Im using and so this is extra bit why I turned back to MSI as it takes my moves well

also, polishing your heatsink with 2000 grit has done this damage, thats why I told you to go for at least 3000Grit or 4000Grit,

you have sanded off the corners or unwanted to sand off areas of copper heart. Now to make things right you need at least laser-cut glass and swipe across the copper core as many times as you need to make it all even, calling shave off out-of-level areas, or take paper cutter blade and just gently evenly swipe trough the surface and see marked areas and unmarked areas. so marked areas will need to be lapped, but now you will need to do it very carefully doing by hand just in marked areas only with gentle pressure and gently after every few polishings check for surface level over and over again. Plus, you will need to sand down aluminium blocks on the heatsink accordingly that go in contact with mosfets nearby CPU socket so your heatsink doesnt get fastened and tilted at the same time. When you see the copper is all nice and in one level take small brick of glass and wrap 4000grit around it then start slowly dragging the heatsink copper part over it while barely keeping your finger on to heatsink softly touching it down to sandpaper on even surface... I thought you knew how to do that..

 

SMOOTH surface of heatsink = BAD idea

 

@ULTRA: I see you are going to mod you gtx 560m heatsink to it hd7970m? Could you post a guide then? Because our card is the same Or you I have wrong about that? And it would be nice if you could get the G60 keyboard work with backlight

That is why i dont want to upgrade my gt 663. Because i need to order a hd5870m heatsink and the laptop does not have backlight keyboards.

But im not still sure if im going to upgrade it. I really want a desktop pc. :/ But at the same time i want a LAN computer xD I need to think about this again... But let me know if you get it work.

 

WRONG

bad lapping = BAD idea

its not simple as many may think

Yea Im going to shave off everything of that heatsink and see how it goes there is need of no guide , just take big dremmel tool and work your way out leaving just copper plate in the heatsink intact and the ramaining bits shaved off in the level of the heatsink base

Yea I will make that keyboard work have plenty of ideas, laptop stays laptop, its portable, thats the future of the personal computing, look at the cord lanline phones, how many of us use them these days? nearly everyone has mobile phone now, even my granmas and granpas do, and so nearly everyone nowadays has a laptop too

 

hehe

cpu core isn't flat then heatsinks can't be flat - flat surface is good but for lower dissipation when paste can do the job thab should do the copper heatsink
and that's not the badly polished job - simple always need to check how looks cpu - heatsink connection when you stick both together

my heatsink have visible recess [?] because cpu core have convex structure

 

No, its the heatsink that you have ruined, but you can still fix it.

mobile CPUs are all glass plated core and they are perfectly smooth even flat surface, the paste purpose is to fill any airgaps between crystal clear even flat CPU chip surface and not so clear copper heatsink assembly. Thermal conductivity of the copper is better than the paste, so lesser airgaps and imperfections - better heat dissipation, if you take a look factory finish is not polished but even flat, and if you look with your eye closely you will see surface is far from perfect glass like clear smooth, so more paste needed to fill the gaps more temperature travel is lost, less paste, better heat transfer=better cooling.

I have posted little guide several pages back how to do this properly and seek for best results, when polishing heatsink

 

Im not ruined anything
Now it works almost perfectly - still get 5-6C differencies in temperatures between cores but that's not 20C and 100C= shuthdown with 23x [or even 25 is possible but not measure for example 30Minutes like i do for 23x multipler in prime95 torture test]
temperature to 90C sometimes hits 91-92 because TurboFan starts from 90C

run 7zip packing in 8threads [ht disabled] on 25x and 91-92C max what i get but ofcourse that not cpu killer like prime95

Prime95 cannot be runned on 26x multipler - show error on 1core [like i mention i cannot run with HT on on 26x on TSbench then that's the End of this cpu - voltage mostly]

And other interestly things that temperature don's differ in blink of eye about 20-10C when start killing cpu or stop killing cpu with prime or similar tools
And all that test with original fan plate, acces panel mounted, little gpu heatssink bloked and original fan.

Maybe I do more lapping mean meaking more hole to fit better all cpu core - now i still not sticks in 100%
and my heatsinks is ruined he he but works - that's not possible for flat heatsink for sure or i had two quad cores cpu that have non flat core

 

everything is possible with patience and knowledge. If you have 5-6c differences between cores thats not great, it may be bad paste job but if its good, then its bad heatsink contact with CPU. Use laser cut glass plate to shave off evenly or use paper cutter blade and lap the marked areas using glass brick wrapped 3000-4000 sandpaper.

Dont forget to retrofit and measure cpu to heatsink clearances after every major polishing

 

@Ultra, the gtx 460m and 560m is the same card. Just that 560m is 100mhz more overclock Can i flash my vbios to 560m? Or would i brick the card then? :/

 

I have no idea which is which, I would rather just overclock and overvolt the 460m then flash it. I have mine runing pretty high and can play anything at pretty decent framerates , not even sure why I bought 7970m now haha

GTX560m is great mobile gpu being honest

you can see my OC details on my sig

 

Okey, how much do your fps increase? Stock compared to OC? Which program do you use? I need to use nvidia inspector and can only get from 675mhz to 780mhz at stock volt. But how do i unlock the card so i can increase the volt?

 

Ultra@ Could you also do a guide how to change to the backlight keyboard? Is it any extra cables?

 

I think increase was ~ 8-10fps on high settings, ultra ~5fps

I use nvidia inspetor, I havent overvolted my card to reach this. if 460m limit is what you hit, then you need to flash to 560m if its possible, and please search forum how to because I cant help with gpu flashing in this case.

For backlit keyboard mod , you will need to disassemble entire laptop to make successful mod, alot of little and precise work and it will be done. Untill I havent received keyboard I cant do it, cant do it - cant tell you what to do, so watch the space I will let yous know when this mod is in progress and etc.

 

About that polished heatsink. Doesnt polishing decrease the surface area. I thought thats why people actually scuff up both the cpu dye and heatsink with 700grit sand paper.

 

polishing off cpu dye is for desktops, for laptop-guess why did I mention 3500-4000 grit only? thats why I said you will now need to shave some of the aluminium blocks on the cpu heatsink too to fix the problem and finish off with only very fine grit paper

 

Hi guys. I will stay with my GX660. I bought Clevo P150HM on ebay, the guy cheated me,PayPal gave me back my money.I even bought 2860QM before I even get my new notebook. Meanwhile I have sold 180W PSU, 5870M modified heatsink, HD6990M card, I was so close of selling my 940XM CPU and even an MSI GX660, but I did not. So I will start again modding my machine. Already bought 3 heatpipe heatsink for 7970M, still looking for 7970M card, will keep my 940XM and will buy new PSU. The story begins again

 

Sorry to hear sad storey on being cheated but glad it all ended in your favour
congrats with gx660!!!

so you now have unmodified heatsink and are looking for 7970m, good there is one 7970m in nbr fs secttion cheap, 330e posted within eurpope but Im not sure if it has enduro bios or not, if it does you will need blind flash to dell vbios. bit worth a shot its brand new i have seen.

 

@vwrafi
you already sold 6990m - because still see you auction here

 

Will wait until price fall under 300 euro. And do you think, that backlit keyboard will work with GX660 ? I do not need to control the brightness of the keyboard since it was allways on max on my previous notebook.

It is there, but I will not gonna bump the thread again.

 

the keyboard will work only uncertain what colour but I have ideas how it works and how to set permanent colour, in worst case scenario it will have at least one unknown colour but lets hope its not a rainbow and not some pink purple etc...

300 or 330 not a big of a deal , sure if there is no need why rush buying it, wait another 6-12 months they willdefinately will be around 250-290eur but not seeing them costing less

 

hey guys, just got my laptop back from 2nd rma 4 weeks ago and the laptop keeps cutting out when plugged into the ac adapter, and the tip is ridicoulsy hot , naturally i assumed i need a new one so got a new ac adapter ,power supply and battery but still the same problem ? any ideas?

 

RMA again, demand for a replacement this time... can be loose DC plug hole check with tweezer and needle ... unlikely they have replaced with improper size DC jack

 

replacment unit? worth noting evrytime ive had to rma its been to do with the dc plug hole stopped charging , so yeh ill rma it asap

 

Dam, still no cheap 920xm's around.

 

what about this 940xm QS? Intel Quad Core i7 940XM Mobile 3.33Ghz 8MB CPU Processor QS Q4AP # | eBay

 

Looks good. Is that a good dealer? I am always suspicious of those army camo china retailers lol.

 

I duno how good or bad he is, I suppose if he is on ebay and taking payments via paypal, posting worldwide, I think there is not much to go wrong, sure you may wanna ask him if he can value item low low price when posting to you so you get away with customs import tax, otherwise it may not be worth attention either. Yea its little expensive, i remember picking my 940XM QS half year back for 180eur incl postage but that was pure luck on ebay. it comes and goes... that seller seem to have alot of stock, I may suggest you wait if you can, if you cant you can buy that on too... just keep on searching ebay daily I know its hard to find

Just bought these and hopefully getting a 940xm in the next week.
Excessive i know but i like the stickers on the ram sticks ..

 

haha nice one, but do you know your laptop board and CPU cant drive 1866 MHz memory? max 1333MHz and if ram has XMP profiles maybe you could overclock that from 1333... but Im very sceptical thinking you may not be able to boot your laptop with this memory... or maybe you will be able to but it will perform at the same speed as your previous RAM... You may as well be better of CL9 12GB DDr3 1333MHz Kingston ram for the same price, which I found good performer in my past GX660R ... or maybe you get to run that memory at that speed I dont know...

I just went in to an experiment yesterday where I have destroyed myth of "8GB and more is an overkill for everyday use" haha! so here I go, not that I also use VM's and some high scale data processing(and I was doing none of these at the time), I was archiving ~6GB files archive with 8threads on cpu, and just few lightweight processes in the background absolutely nothing major etc, messengers and firefox opera etc, so 7zip was doing the job and I see my gadget toolbar RAM status has jumped to 8.1GB RAM used of 32GB RAM available while it was archiving, and I wasnt doing anything serious yet, so here it is, myth busted

@savier

I hope your experiment goes well, then I may be tempted for 16GB 1866MHz kit for my own laptop

 

Will this processor work in the Gx660r?
