~GX660(R) Owner's Lounge~

I sold my GT780DX. Still have to sell the 7970m..
I need to fix my car too..Once this is done i'll start saving for a new (and smaller) notebook
I just hope it comes out fast

 

You could always look out for a barebone I suppose with a low end GPU and pop you 7970M in it like the P150EM or its replacement.

 

Performance wise there's not so much difference between haswell and ivy bridge..I'll stick to ivy and 675mx for now

 

hi mates, i'd like to know if adding the third ddr bank (the under the keyboard one left) could increase memory bandwith with i7 840qm (i'm planning to get a i7 920xm now), now aida benchmark scores my 2x4gb kingston hyperx@1333mhz something like 14300 "points"...
I've read in the past that timings pass from t1 using 2banks to t2 using 3 banks, isn't it?

PS i don't need at the moment a larger amount of ddr but i'm wondering if this upgrade can increase raw performances someway, thx!

 

Hi,
I already got 920XM CPU (still waiting for some free time to install it in my GX660) and I'm wondering if I can upgrade GPU to 780M.
Someone said it's MXM 3.0 B so there shouldn't be problems, right? Won't the 920XM bottleneck the 780M?

 

most likely it wont work in GX660 series and GT680 series laptops because of yet unknown reasons just like 680m never worked, so its the same architecture and design card so expect the same outcome. Best shot is 7970m max performance money can buy for this machine!

 

Not really good news for me.

I've read here that people had problems with 7970M even when it was Dell card.
Would you please post some list of important attributes to look for?
I want to minimize the chance of getting wrong card.

 

well some newer dell cards dont work just because they have newer VBIOS require UEFI boot support, thats why

also my personal experience tells me card that has under 1.0v @ GPU from standard may not overclock well or may not be very stable at all, I may well be wrong but just my own past road of pain that i've went trough before.

For yous record - I have 7970m DELL OEM card that I can sell, I had it in my GT683R and my MSI laptop had no UEFI boot support and my card worked 150% perfect and overclocked when tried on benching like an animal to 1GHz for the test, also temps were very good at iddle, stock load and OC load never cross 78c+. PM me if interested, maybe some time later I may just put her up to the FS section, dunno yet.

So thats that

 

again you selling msi ?

 

again... just did :/

 

hello mates. i'm trading a i7 920xm for my gx660 and need some advices: i'm using an unlocked bios witch includes some options for extreme processors, i can change multipliers from here but if something goes wrong probably i need a clear cmos everytime i guess.
Most people uses throttlestop but i need advices how to set it properly: my aim is to set something like 2400/2600mhz in quad core but i dont know if some vcore increments is needed for that...

 

I wonder if anyone has successfully done so. I did not use unlocked bios, because stock bios already has options to configure just about everything (Using CRTL+shift+alt+delete I believe, UltraGSM probably remembers better) and I remember tweaking with it but I didn't get the proper configuration.

 

I never used bios OC menu options, they may be very inacurate, I always have used throttlestop and it was easy as piece of cake. OC on the fly and I was able to get more than 2.6 on all cores if cooling allowed if memory servers me right. If you read past pages of this thread you will see how many of us had XM chip and OCED it HIGH, look at debianik posts here, he has done some crazy OC on his MSI lately too all only via ThrottleStop

 

That sounds great! Dont know the gx660 capability of managing high oc with only one fan available, i'll search for some throttlestop guide.
Using my actual i7 840qm i can only set the turbo ratio to 15, gaining some MHz from 1867 to 2000 on 4 cores...

get the 940XM and get all the power of the beast your laptop can get! Prior getting XM chip buy yourself ICD24 thermal compound and you will thank yourself money well spent with temperatures lowest possible! Sometimes some mods and sacrifies needed but keep on reading this thread backwards you will see some nice results!

Best of luck

 

Thanks for you advices, i always use arctic mx 4 but if there's a noticeable gain in temps i'll search for it!

I recall 5 to 10 c difference , which is ALOT for my experiences in same laptop, Ive tried several, and I would prioritize only few of many I have went trough, and sort this way :

#1 ICD24
#2 Phobya Hegrease Extreme
#3 ICD7
#4 MX4

ICD24 cost alot I think for a reason, so as phobya hegrease extreme

 

Up to 10 degrees is a lot! very very good...
Someone had ever used coollaboratory liquid ultra? Don't know if it's quite famous but i'm posting their link: Coollaboratory Liquid Ultra - top performance for High-End systems!

I've bought it almost one year ago, for my i7 3770k on desktop but i've never opened it, since the product erases every signature writed on the cpu...i still have it and maybe it's time to try!
...but please stop me if i'm doing wrong risking to damage something...

 

since its made from 100% metal try to use minimally with the thinnest layer possible.

Because you're using it on a portable solution - laptop, I would imagine when it heats up and liquid agent evaporates you are only left with metal dust/bits of residue around the IC so it may get loose and fall on to other surrounding components within your laptop and may cause bizarre consequences. I would try to use only ultra-tiny dot of it since its metal formula it is very very highly conductive and can short your CPU as your CPU has exposed electronic components around the CPU die... I would be sceptic on this but I may be well wrong maybe it cures and does not have tendency to get loose like I imagine

 

Yes, for sure that was my primary fear about it, the product it's not so used and there are few feedbacks...of course looking at reviews this liquid metal seems to have great performance indeed...do you know someone in this community who have some confidence with this particular compound?

PS sry for my english, i suppose it sounds quite a torture for uk friends! lol

 

your English is just fine nothing I couldn't understand


I dont know anyone who has used it in the laptop. Was it like sky expensive when you bought it? ICD24 cost around 20EUR per small tube but works miracles and PhobyaHeGrease also is amazing solution performing close to ICD24 but slightly cheaper, I rather go safe than sorry

 

If i remember well, probably costed something like 20 euros, now i'm looking for innovation cooling diamond 24 but it seems hard to find here in Italy, according to some ebayer sellers (Germany and Uk) the price is a little under 20 euros but i have to add international shipping costs...i'll search better in my country, looking at stores specialized in watercooling and modding...by the way the tube is only 1,5 grams...really diamond made!!!

 

good stuff always cost! I dont know how truth about the diamond it is , but it works like a champ!

 

he he, for sure, and no problems when it worths! i'll try to find it and i appreciate your tips, i want to use every "trick" to squeeze the new cpu safely and managing good results.
I use also a zalman nc3000u cooler base, it allows me to reduce 5 degrees on my actual i7 840qm so i hope the mix of different techinques will allow me to reach a safe 2400-2600mhz setup without reaching 100 degrees in gaming!!

 

arctic mx2 6-7 dollars for 4ml

todays modification : bridge connecting both heatpipes with two heatpipes - not finished but results show big advantage

145W on ts bench on the wall, to 150W under hanbrake (but that not 100% cpu usage)
before without HT it hardly manage 140W under 90C and gpu temp was about 40C and sometimes lower (mean a lof of air not doing anything for cooling cpu like now)

ps
dont comment 0 and 3 core i know about that

 

simply incredible for me! i hope to reach something not so far from these results...but is this a 24/7 daily use setting? i always thought that far above 3000mhz on four cores meaned over 90 c degrees!

 

26 1-2 core and 25x 3-4 looks stable (27x like on screenshots not really working correctly because of too low voltage)
and i don't use HT then it's even more room

for better speed need overvolting that cpu (similar results get 940xm) - then no sense of buying 940xm if you get the same multipler on 920xm

of course that need:
polishing cpu heatsink,
drilling holes under fan,
use notebook on some cooling pads or something that move higher back of laptop to air goes without blocking to fan
and connecting both heatpipes helps in CPU only or GPU only working - mean always both radiators do something usefull

mine "cooling pad"

 

hey mate, you squeezed your system in a great manner, lot of useful tips, thx!
So using HT off probably 25 multiplier is the goal to reach, without adding steps to vcore i suppose.....by the way, what's the default value for i7 920xm voltage? have you increased it whitout issues?

 

Pushing an i7 920xm to new levels by increasing the CPU core voltage
measuring and overvolting

overvolting doesn't works when i test 720qm :/ measuring works and it's similar (only on load is lower)

 

i'll take the necessary time to read everything, very useful for sure....maybe would be a nice idea modding the back cover with a metallic mesh as alternative to adding holes, i'm thinking about it...
What about the added heatsink to bridge the to heatsinks...it seems a nice idea, maybe it will work even adding some copper sticks..

 

My 940xm is for sale if anyone interested - http://forum.notebookreview.com/computer-components/719540-fs-intel-i7-940xm-es.html

Was in my gx660r for a couple of years with no problems. The 7970m is also for sale but is probably sold already, if not will post here again.

I'm in contact with a friend, he probably will trade his i7 920xm for my i7 840qm plus money, we are trading this, but next week i'll have the definitive answer about it...in case of no trade i'll contact you if still available, by the way what's your experience overclocking that cpu? i'm planning to use my laptop at least one year more, then to switch to something else, so i want to be sure to squeeze it as far as possible...

 

Hello. I'm just wondering if what SSD should I buy for my GX660? There's too many SSD out there and most of them are SATA 3 interface. I know that it's backward compatible but if I'm going to buy a Samsung 840 Pro or Crucial M4, will it make any difference on my laptop? I've seen some benchmarks and clearly, the 840 is faster than the M4 but on my laptop with SATA 2 interface does it matter?

 

With both those drives at SATA2 speeds difference will be minimal (they both do more than 270MB/s normally). Only thing you will notice is battery life. The 840 Pro consumes much less energy than the M4. Since those are fast drives, they will be idling around 70% of the time. That is where the 840 Pro shines regarding energy consumption. Also with the 840 Pro, newer notebooks will be able to use it at it's fullest, if you plan on getting a newer system in the future. If you'll be keeping your notebook for some more than getting a M4 is cheaper.
It depends on what you plan on doing.

 

Samsung 840 pro series is an outstanding product line, the best balanced mix between price, performance and longevity, i'd choose one without doubt: both products will probably fill the sata2 bandwith, as for my corsair force 3 240gb, with "old" sandforce controller, but it doesn't matter since there are so big advantages even with this cap.

 

Both samsung and crucial are good solutions. As others have mentioned, the 840 pro might make more sense if you plan keeping the drive for a while as you can use it as a boot disk on a newer system unleashing its full potential.

 

Is $1000 for my setup in my sig a fair price? Looking for a quick sale.

 

Yeah it's more than fair. To be honest.

 

Thanks for the reply Ryzeki. I will probably post it in the marketplace later. I just don't want to get stuck parting it out.

 

It's a good price, in such level that I might even bother you to buy it x_x hahaha

 

hey mate, many congrats for your new monster in signature, i think your price for your upgraded gx660 is very fair, honestly i'd suggest you to resell the components but i know it would take time and it's not quick for sure, every part is quite requested since not very easy to find.
I.e i searched an i7 920xm for long time but is not easy to find and the ebay sellers are very expensive....best luck!

 

Yeah, the parts do mean you can reach a wider range of modders.

 

Thanks for the replies. I'm leaning towards the Intel 330 now because of reliability. I think I will stick to my laptop for 2-3 or more years and I really don't need the fastest SSD, I just want the SSD that will not give me any headaches.

My question now is, will it work on GX660 without updating the BIOS? I've read some post here long ago that some SSD doesn't work (I think it's Vertex)

 

Usually intel ssd old series worked correctly in ahci mode with official bios releases, but if needed you can use an unlocked bios version (in this thread you can find some versions)

 

just received and installed my i7 940xm, finally i can change the multipliers! cpu run fine at 3ghz on 4 cores, temperatures are quite high on 3d mark benchmark tests and synthetic ones. with ht enabled i hit 93 °C if i not force turbo fan, but during games i've never seen something higher than 85°c.
I need some explanations about throttlestop: i need to know if the settings run automatically in background when windows 7 starts or if i need to run manually Ts everytime.
Last, what are the safe settings for tdp power? i've set 65w-55w (looking on some images in techinferno ts thread guide) but don't know if needed.

 

create shortcut in autostart in START menu
rest you can set in TS

i'm not blocking TDP both 99/99

hmm good temp for 3GHz

 

thx for your advices, i've followed it! temperatures are unusual for me, never seen a cpu desktop or mobile touching 93 degrees, now i'm ready to cook my eggs!!! he he, joking of course, performances are great compared to previous i7 840qm, very happy indeed

 

Congrats on that new CPU. The XM series does tend to run warm. I never really had to OC mine for gaming. I usually only did that for 3dmark benching. That quad running at 2.2ghz should be adequate for all games and keeping it stock should keep the temps down as well. Good luck with the new beast.

 

stock XM ... what A JOKE - then better stay with i5 - for sure in many games you get more fps

 

No no! It's running 22x133 on 4 cores, otherwise no gain compared to i7 840qm i had...
