DDR3-12800 (1600MHz) on XPS 15/17?

We know i7 2720QM & i7 2820QM have support for DDR3 1600MHz, but Have Dell XPS too?

Let me know if anyone has tried to install this type of memory in its XPS.

Of course, test must be make without other kind of memory installed in your system, because the system will adjust the performance to satisfy module with lower freq.

I have found these:
Datasheet Kingston

Link to buy Kingston
Newegg.com - Kingston HyperX 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model KHX1600C9S3K2/8GX

but maybe intel XMP can be a problem?

I also found these:

(sorry for my English)

 

I have just read that 1600MHZ ADATA modules have XMP profile like Kingston modules , so if DELL XPS not supports XMP profile can be a problem?

Without XMP profile these modules can work at 1600MHz?

Patriot memory modules are at 1600MHz too, but have horrible CAS.

No one is interested in memory upgrade to 1600MHz?

 

I installed HyperX and it runs at 1333mhz.

 

Probably looking like at this point we would have to wait for Dell to enable XMP from a BIOS update.

 

from ADATA website FAQ

5. Why my DDR3 1600G only show 1333Mhz on my system ?

Ans: because of DDR3 1600G adata products that SPD is setting by default 1333mhz.All the setting follows JEDEC definition. It is to ensure your system keep working if your MB,CPU can’t support 1600 memory products.

from Intel website
Extreme Memory

"First boot" with default JEDEC setting on a platform that supports DDR3 standard JEDEC specification (your standard DDR3 memory frequencies), ensuring base functionality. Then user can enter BIOS and manually change settings or use the Windows*-based Intel® Extreme Tuning Utility.

So, if there aren't memory setting in XPS Bios, maybe we have to search Windows*-based Intel® Extreme Tuning Utility, to set memory profile by Windows.

Do you know if this thing has never happened in the past?
At this moment I believe there isn't one setting for memory in the XPS BIOS and I do not think Dell will even enable XMP profiles.

 

I just had a response ( from this blog) to my question on the support 1600MHz by XPS:

 

I'm hoping Dell will add the support too. I was also disappointed in that the BIOS wasn't GUI.

 

I won't hold my breath for a BIOS update to enable XMP.

 

would there be a significant performance increase with 1600 mhz?..could it cause timing issues?

it is disappointing that only 2 ram slots are available in the non 3D option..i went for non 3D for the optimus option with a 2730qm being concerned with heating issues..8 gig ram is ok with me though

 

Me too, however my WEI memory score went up significantly. I went from 5.9 to 7.6, probably due to the faster timings. Also there are utilities I'm researching which I hope one of them will allow me to run the memory at 1600MHz.

 

sure that wasn't from increasing amount of ram? My scores increased like that when I went from 4 to 8 GB

 

This.

Timing has nothing to do with it.

 

Same as well upgraded fro 4 GB to 8 and WEI went up from 5.9 to 7.6

 

You won't notice any real life benefit with the same amount of memory but going from 1333MHz to 1600MHz since memory bandwidth is never the limiting factor (except when you do not have a discrete GPU and game on integrated graphics).

 

Kingston HyperX 1866 works at 1866 with no issues in my xps15... WEI went from 7.6 to 7.9. Also, the Lenovo y460P with the 6230QM worked at 1866 speeds with this memory as well with no apparent issues and again wei went from 7.6 to 7.9

Noticeable difference in video editing in regards to system responsiveness when realtime editing compared to the stock 1333 ram. Encode times are the same though.
