I just finished reading some old threads here regarding the max RAM that will work on the CF-30 Mk3 being 8GB. I know that the Intel GM965 chipset in the CF-30 Mk2 will support more then 4GB, yet I also know that the BIOS may not support the memory remapping required to use all of it.
So now I have to know, will my Mk2 work with more. I have found 200pin DDR2 PC2-5300 RAM in two 4GB sticks, but has anyone here already done it on the Mk2?
I am sorry, this stuff is like hanging a red cape out in front of me!![]()

I am very curious also, but, I don't have the funds to invest in 4gb sticks for an experiment...Now if someone gave me 2 sticks, I would gladly try them out and report back...Might even load a 64 bit OS on a spare drive to try.
Anyone who wants to send me the 8gb of ram, send my a PM for the address

I have seen a screen shot of a cf 30 or a 19 mk2 with 8 gb of ram somewhere. Also look at the 74 mk3 and 52 models with the same chipset.

It's too late, wyrm73 and ADOR provoked me over at Toughbook Talk and I have pulled the trigger and intend to find out.
Now to work some overtime... - 
 
 are your 4GB sticks double-sided (low-density), i.e. memory chips on both sides of the stick ?
if they're not double-sided (i.e. single sided, high-density), then I don't think it will have much chance of working.
the kit I've used on the mk3 was double-sided, so that should be your best bet also, especially on the mk2, as it is an older chipset.Shawn likes this. - 
 
hold the presses! MK3 can have 8 gigs? any recommendations on brand? not that my 32 bit installation would use it, but I might install 64 bit windows if I ever have time and am bored silly.

 I am not sure that I am following your post. You seem to be advocating for low-density, which is what I went with. I ordered (2X4GB) of SODIMM 667MHz 200-Pin PC2-5300 DDR2 1.8V LOW DENSITY 16 CHIP, Notebook memory modules.
Thanks for the feedback! - 
 
Low density ram has historically been more compatible in all makes of computers. Low density ram always costs more. Usually quite a bit more. When in doubt or experimenting, Always go with low density.

Well when I took a glace at the Intel GM965 Specs sheet I conjectured that low density was my best bet, but we will know soon....
I appreciate any and all input I receive, including the ones where "they said that it couldn't be done..."

Please educate me...what specs indicated that low density was the correct choice?

If I am right you were told that 2GB would not work in a CF-29 but we all know how that went :laugh: - 
 
 you're welcome
     
I've edited my post anyway, but you've already got my point. :thumbsup:
look here, it's in the first pic.
the credit for choosing that particular model/brand goes to user BaRRmaley, who told me some time ago what he had used for his 8GB 19mk3.:hi2:
I had a bit of a saga when buying those sticks from the bay, as 2 sticks were DOA and one gave memtest86 errors. i got a refund, though.
you can use any good brand, as long as you go by the specs recommended in this thread. -

excerpt from thread
My 2x4GB is finally here
Elpida 4GB 2Rx8 PC2-6400S-666
I've already installed one of them, so now I have 2GB + 4GB and it works fine under 64-bit OS.
Will upgrade internal 2GB to second 4GB module soon, but it seems, while 4GB is not enough, 6GB is.enough. - 
 
 I have been searching for hours for what I referenced! I think it was in the Intel 965 Family Data Sheet, but I can't find exactly what I saw now. The System Memory Support is listed in section 1.1.2.
Anyway as I understood it the PM965 chipset with the latest update would recognize 4GB of Low density RAM(128Meg X 8 Modules). and the datasheet said that all features of the PM965 were supported by the GM965, unless listed otherwise. - 
 
when I have those moments, I use browser history. If I know the approximate time and correct date, I can find the bread crumbs..

It case you find this thread and wonder the answer, it can be done.
