Re: M17X

Hi and thank you for your reply, o.k. this is what I've done so far.... I went onto Dell's Website and went to support and entered my 'Tag Number' for the memory selector and a picture of my laptop appeared and it showed my tag number under it, it has showed me this memory to buy for my system as follows --- (SNPFYHV1C/4G --- A6994452) and the specs are as follows --- DDR3-SDRAM-SODIMM 204PIN (NON-ECC) 1600MHz PC3-12800  DUAL RANK-UNBUFFERED 1.5V and so I went ahead and bought the brand new original Dell Manufactured memory cards for my system now and they should be here by Monday by the latest and I'm praying that the information I received from Dell is correct. Another question about the laptop in your message you wrote M17XR1 and where is the R1 coming from because when I enter the tag number on Dell it never shows a R1 and my laptop does not show a R1, so what is the R1 lol......... Let me know about the information I've sent you and thanks for the help

According to our records this system (M17xR1- Mid 2009) will support memories that run at DDR3 1333 or 1066 MHz SODIMMs, the one you bought is running at 1600MHz that might be the reason the system not posting with the new memories. 

A lot of machines are referred to as R1 for 1st revision, but on the site, it doesn't show this, just R2 and higher.

As for your memory, is it running proper voltage and latest BIOS? Do you get beeps or just black screen? Your mem being 1600Mhz should be fine since the DELL site offered PC3-12800 which is 1600Mhz... But if it wants to run at 1333Mhz, it would downclock the RAM to do the same, just with room to overclock now. :) But voltage can affect it if its supposed to be at 1.5, and the BIOS may not recognize it if it has a whitelist, and runs lower voltage.. :(

Check the SO-DIMMs that are in the machine that work, the speed and specs should be on the PCB side if there is a heatsink on one side. I've never used G.Skill so can't say much on reliability, but maybe a bad SO-DIMM? I use Corsair for all my machines personally and my M17xR2 worked fine with the Corsair.

You can try to reset your BIOS to defaults, then save and shut down and swap RAM, or try to add the new ram and do a CMOS reset and power drain (remove battery and adapter, hold power for 20 secs, put battery back in and AC adapter, then turn on)..

Hi again and thanks for the help, the bios is A07 version and I'm not sure about the voltage because I'm not sure how to do that and when I turn it on the keyboard lights come on with the fan and the screen stays black and the 'Cap' light begins to blink non-stop and the other lights next to cap light stay on solid with no blinking and no beeps at all. I guess for now it's a waiting game until the new memory arrives and another thing when I have the g.skill in I have to force a shut down because the screen not being on and I put the old cards in and start it back up it starts normal without it saying that the computer was shut dowm unexpectally.

Some boards and BIOS's are picky with the ram. Try one stick only and see what happens. Till you get the new ram, its all trial and error. :)

well if  it   is a M17x R1 ... it   supported 1066mhz and 1333mhz. some have gotten 1600 to  work  but  downclocked to 1333,  and  max supported was 2X4 gig   sticks..

anything above that is  hit and miss, you can try as stated above by reseting cmos, but from my understanding and reading 1600mhz, not all work some reported success with Kingston hyper X other with corsair value...   guess it  depends if   it was made  on a Monday or  a Friday thing lol
