1333 max with the quad cores

Ok so I'm upgrading my M15x, with I7 920xm, GTX 660M 2GB GDDR5 MXM 3.0b, Crucial Ballistix Sport (2 x 8G) DDR3 1600, and a 240w PSU. Is there a certain order that I should start with first? Any help would be appreciated. thanks! This is my first upgrade on this M15x and I don't want to screw it up.
First thing I would say graphics card, but take a look to a 770m if you want a good compromise of power cost and heat, than 920xm + PSU (the best is the 330W ) and then the ram.
-
How about the Crucial Ballistix Sport (2 x 8G) DDR3 1600? I've heard these will work if you clock them down.
I don't know, if you want I'm selling mine, PM me if interested

I upgraded my iMac 27" twice. First from the stock Radeon HD 5750 Mobility to the Radeon HD 6970m from the newer 2011 Model and a month ago to a Geforce GTX 780M. As expected i lost my initial boot screen with the upgrade to the Geforce GTX 780M because the card doesn't have UEFI Bios.
So, any card until the Geforce GTX 700 Series should work on an iMac which support MXM cards (2011 is the last model, graphics card in the 2012 and newer iMacs are soldered to the logic bord).
I'm going to put the m15x 780m into a 2011 iMac 27, I have Svl7 firmware installed on that card, do I need to do something else or just move it ? There's no way to put the 780m new iMac firmware into this card ?

Corsair 1866 is what I have. I would totally recommend it.
The problem with the corsair is that the D9 chips are not 100% sure as it happened to me
-
How do i check the chip is Micron D9? . I thought the ram were the same as yours, and because that, they would have it haha
They should, but better double check before make some mess, just lift the adhesive and read the chip, do it carefully
-
Ohh, thanks so much pal Astelith, for answering me so quick.
I already have them installed and ready for fight hehe. But they ar at cl8/133mhz for now, because i am a neophyte in Thaiphoon Burner i fear...
When i get to flash them to cl7 , i hope to achieve your excellent 3dmark11 score.... hahah ( i am at 75xx right now with the 680m and 920xm. I suppose the 780m is a holy cucumber XD)
Yeah, she kick hard ! Check the chip before attempting a flash
-
Hi Astelith.
So, did you flash that ram to Cl7 succesfully?? Did you notice a boost on 920xm?
I have found a cheap 8gb kit, and i'm going to get it, but i thought it reachs only cl8 1333 mhz.
This could be my very last upgrade for my dear grandpa ^^
( well, until maxwell 20nn appears xd)
Yes, I'm running CL7 but, honestly, we are not talking about a big performance leap.
For sure you can notice some differences in benchmarks but in the daily use it's more or less the same, the big job it's made by the 920xm, the 780M and the SSD.
If you can have it for real cheap take it, but don't set high expectation about performance
-
Nothing new for the corsair but I got for cheap this: http://www.kingston.com/datasheets/KHX1600C9S3P1K2_8G.pdf and surprise... with Micron D9 chips
-
Remember you are talking to a noob here... so could you be a little bit more clear with the modding of the inf of the driver?
To be able to install the driver you need to modify the inf inside the drivers installation directory, a good and easy guide is here :
Nvidia INF driver modding (Guide) - Guru3D.com Forums
You must do the Inf mod in order to get it working, the vbios flash is only the first step of the process.

Of Windows doesn't recognize the card it's normal, just mod the inf of the driver
-
Thanks for sharing your experiences. Unrelated but where did you purchase the IPS screen upgrade for your M15x?
Directly with the laptop on April 2011
-
Nvidia INF driver modding (Guide) - Guru3D.com Forums have you used this guide ? It seems is a inf driver problem, try to redo it, maybe you put something wrong in the inf file
-
Quick update so other can learn from this.
I bought the kit, the first boot ended up in a loop with a restart at windows loading phase, after that I flashed the modules with Thaiphoon burner using the downloadable preset (based on Micron D9 chips) but unfortunately I discovered that the chip inside is not a Micron D9 but a Spectek PEB12 15E (http://www.spectek.com/pdfs/fbgamark.pdf) with the consequence that the ram is now dead.
Now I'm trying to find someone with the same chip to be able to makes me a dump that allows me to revive my chips and make it works (so if you have it please help me )
I'll keep you posted...
-
Very nice ! So the 880M seems to be optimized to go higher in clock... how about the gpu voltage @ 1243 ?
-
What do you mean exactly ? To reflash it ?
-
Hi Daniel,
if you laptop can do the post you can try a blind flash, if not you have to change physically the bios chip, Svl7 can help you to obtain the chip and if you are good with soldering it's a 15 min job.
-
A single 780m will be better than those 675Ms. I dont know what games those guys with 2 overclocked 780Ms are playing, unless they are using multiple screens, 1440p or 120hz screen.
- - - Updated - - -
A single 880m is nowhere near a 780m sli or 680m sli.
For what I've seen the 880M is a 780M with higer default clock, a 780M with the 880M clock is the same card...
9026 graphics score at 3dm11 with the core @ 1000 @ 1V (can run the test even @ 0.975V)
http://www.3dmark.com/3dm11/7948950
Compared to this test http://www.techinferno.com/2014/01/31/review-nvidia-gtx-880m/5/ the performance is 100% the same

I'll take your word for it bro, but I perfectly remember going from the 580M overclocked (to about 3.6GHz) to the 920xm/940xm overclocked (to similar 3.6-3.8GHz) and I most of all remember everything going up from 'acceptable' performance to pretty much blazing fast, and having that pesky max 40fps average go to a solid 60fps, with only occasional slowdowns into the low 40's.
You're bottlenecking that beautiful beautiful overclocked card bro.
Really, I'd advise you to look into at least a cheap 720qm to see the impact of quad-core... you can get it pretty cheap on ebay: Original TOSHIBA A665-S6070 Intel Core i7 CORE I7-720QM 1.6GHZ Laptop CPU | eBay or if you're lucky, even cheaper on forums. I once saw one go for 35$.
Well, if you say so the 920xm will makes me very happy
So by the end of the next week I let you know !
-
Cool the world is small ! For the ram I have like 90 MHz more to go and probably I will keep it lower for daily use, there is not big differences anyway
-
I'm glad to hear it wasn't permanent. By the way, how does that dual-core CPU cope with a 780m?
The i7 620M it't not that bad, I can play almost everything on ultra (2048 x 1152 on Dell 23") with 40fps or more... at 1000 core 1v / 2900 mem the power draw is around 110/120W ...and for that I love the 620M !
But now I've found a good 920xm so let's see
- - - Updated - - -
I'm just interested, can you change that chip without soldering? Also: I've read about people screwing their vbios up that way and they could just do a blind flash.I recover the card soldering a new vbios chip.
-
Mine is Dell, I'm curious to go deep and understand if it's only a rebrand, if is this the case Good for us with the 780m
-
The performance of the 880M is the same of the 780M, with same clock we have the same score... my 780M (Blue pcb) can handle 1000 on the core with 0.975V rock solid granting 9K score on 3dm11
Maybe I have a lucky board...

I found this:
[HowTo] SO-DIMMs Extreme: Boost 1600 to 2133 and beyond / JEDEC & XMP
Basically to buy the Corsair 1866 CMSX8GX3M2A186<wbr style="color: rgb(51, 51, 51); font-family: Trebuchet, 'Trebuchet MS'; font-size: 18px; font-weight: bold;">6C10 kit and to flash it with Thaiphoon Burner
At this point the only thing is to try
M17XR4 upgrade GPU to GTX780M
in Alienware M17x / AW 17
Posted
Here I am
The card was mine, the bios is the one of svl7 so I don't think is a gpu problem, can be the main bios the source of the issue ?
