Questions about CF-19 MK6

Hi,

I recently purchased a CF-19 MK6 and have a few questions about it's upgradability, as well as specific parts compatibility.

I'm located in the US, and the model I ordered is a US market model, so all the localization questions should be answered with that in mind.

I've read that the half extended antenna covers for the MK6 cannot be replaced with flush ones, is this true? I noticed that there are quite a few pictures of MK6s for sale, as well as promotional shots that show them with the standard flat antenna covers.

I can't seem to get a clear answer on ram upgradability either. All of the refurbishment websites I visit give you the option of selecting 16 GB of DDR3 ram for the MK6, but on this very forum, I've read posts from users that suggest the MK6 only has one SO-DIMM slot and cannot accept more than 8GB, assuming there isn't a software issue, you could only use 16 GB of ram for a MK6 if a 16 GB single DIMM is compatible.

Upon further research, it appears only the camera models of CF-19 MK6 have single DIMM slots, non-camera ones have two.

However I do still have a question about RAM, am I limited to 1333mhz max? I see that some retailers carry 1600/ 1866 mhz memory; Also is the L suffix on DDR3 important when ordering ram for this model?

 

The CPU is an i5-3320M and ARK says memory supported is DDR3/L/-RS 1333/1600.

I upgraded one MK6 with Crucial RAM 2x8GB PC3L-12800 (1.35V) and it works fine. I tested also with Samsung 2x4GB PC3-10600 (1.5V) modules and it also works but only used them for a few days so I cannot say how it performs in the long run.

Memory should also be the same for MK7 and MK8. 3rd Gen Intel CPU.

Regards!

 

the L suffix should not be important as i5-3320m is a 3rd gen cpu, which supports both.
you should still get the L version to prolong battery life by like 5-10%

Antenna covers can be swapped. Just make sure you get them for a later mk. As the earlier ones mount differently.

 

Are you sure? I don't have mk6 with factory gobi, but on mk3 antennas had a special design to make such a change (half ears to flat) impossible.

RAM works at 667 (1333)MHz, so 1333 or 1600MHz is ok. Mine is 1600@1333. 2x 8GB of DDR3L.

 

Post a photo of those antennas please

I have a CF-193xxxxx with flat covers on it.

 

Mk1 and mk2 antenna covers are the same as a CF18. Mk3 and later are a different design. I have swapped winged and flat on a mk3 and maybe on my mk4. I can not remember for sure about the mk4.

 

The flat and half wings on my Mk3 19 swap no problem.

 

It's possible to install wings instead of flat but not vice versa
I prefer wings (and install them on my current CF-19) because they are so cool for palms massage )

 

Do you have any pictures that illustrate this?

 

Right now I'm in mountains without those laptops, but I think I will check it on return (a few days).

 

I just pulled flat antenna covers off a CF 19 mk6 and replaced them with winged covers.
No issues.

 

Tom, thanks for the response, did you happen to see if the CF-19 was underclocking the 1600mhz ram to 1333mhz? All in all, the 1600mhz is cheaper at the moment, however I'm curious to see if it's utilizing those extra few hundred mhz the ram is capable of.

 

Here is a comparison photo of winged and non winged.
I see nothing that will prevent them from being interchanged.
Both types have a right and a left that are different for each side.
Also to install you must slide the top into a slot first, then push the bottom over and onto the lid.

 

Shawn, thanks for posting the picture, looks that way to me as well.

In order for there to have been an alternative antenna design that needed the winged covers, one would assume the half wing would have to be hollow to allow for more space; Looks solid or at least closed off to me.

I went ahead and ordered some mk3 flat covers.

 

Hope you will not have problems with that, but I had )

 

I just don't see where you had problems as long as you swapped 18 Mk1-5 and 19 Mk1 and 2 together or the newer body style 19 Mk3 and up.

Not that long ago I put a Mk1 bottom onto a Mk3 19. I had to take a plastic part out of the Mk3 and it dropped right in.

 

Got my MK3 antenna covers in a week or two ago, they installed identically to the existing half extended covers that it came with. No hiccups, nothing broken or forced.

Tom, did you happen to see if all 16gb of the Crucial RAM was recognized by the MK6?

I have an identical set of ram from Crucial and it's only recognizing 8gb with both DIMMs inserted. I've tested both DIMMs individually and the BIOS can see both of them, so they're both functional to at least that level.

 

It means I had a special "Monday" edition of cf-19khragam )

This is my MK6 with Kingston RAM. Had Crucial before - ok too.

 

Hmm...the only difference I see is you're running 1333mhz ram, I bought 1600mhz, even though ARK says it's compatible, it may not be.

However tomcatsniper said he was running the same 1600mhz Crucial ram in a MK6 and said it had no problems either...

 

Mine is 1600 too.

But you had no problems changing "wings" to standard antenna covers, so there is a parity )

 

Well I'm not sure what else it could be; I think I'll return these for a refund and actually go with Kingston like I should have in the first place.
