Best ram for the m15x

Recommended Posts

Hi All,

I'm considering to upgrade the cpu from the 620M to the 920xm and the memory will raise from 1066 to 1333, anyone ghave a good ram suggestion for me ? Does a low latency will help performance ? (gaming bench)

Thanks in advance !

Definitely 1333Mhz CAS 9 or CL9. If you can get CL7 that is even better (should be equivalent to another multiplier on the cpu) but its usually very expensive or hard to find.

I've heard different things about getting 1600Mhz CAS 9 RAM whether or not it runs at lower CAS due to downclocking to 1333Mhz.

Hopefully someone here knows more about that.

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...

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

Last year i installed two modules of Kingstons HyperX 1600MHz in my M15x. They're running with CL8-8-8-23 at 1333MHz. I'm very satisfied so far and they aren't too expensive.

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 :)

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

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.... :P 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 ;)

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

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 about the Crucial Ballistix Sport (2 x 8G) DDR3 1600? I've heard these will work if you clock them down.
