Thank you so much. The dell community is so awesome. i am a newbie here and i got answers so soon. and the machine i use is also is kinda old (its still so good tho).
btw as i saw online, it says that the highest speed of DDR3 is the lowest speed of DDR4.
@JamesJAB1 I tried and no luck please advise me as to what am I doing incorretly : Intel Core i7-3520M CPU @ 2.90 GHz also channel mode at Dual interleave 4 ram sticks 1600-MHz, DDr3 Timetec new
Thanks I love this machine its been 4 years in the works restoring it from the recycling center
Hello, I have a problem with my RAM. I have a Dell Precision M4700 laptop, which has an Intel Core i7 3940XM quad-core processor, a motherboard 082H3V A00, BIOS A19, a 320GB HDD, an Nvidia Quadro K1000M, Windows 10 Pro, and 2 Kingston RAM modules of 8GB DDR3L (1.35V) with a frequency of 1600 MHz (12800) each, for a total of 16GB.
The problem is that I want to upgrade my laptop's RAM to 32GB, which is the maximum supported by this device. So, I bought 2 new RAM modules that are exactly the same as the ones I already had, from the same brand, capacity, model, and frequency. However, when I install these new modules in the empty slots, the laptop simply doesn't boot up. It doesn't show the Dell logo. It's worth mentioning that both the RAM modules and the slots are fine, as I tested each memory and each slot separately, and they work. Also, when I install 2 out of the 4 memory modules in slots A and C or B and D, they work. But if I install a third or fourth module, it simply doesn't work, which is illogical since my processor is quad-core, and theoretically, it should work without any issues. Any solutions? Regards.
Saw this info on another site where someone had the same problem......
Try running memtest86 on each of your ram sticks, one stick at a time, up to 4 passes. Only error count you want is 0, any higher could be cause of the BSOD. Remove/replace ram sticks with errors. Memtest is created as a bootable USB so that you don’t need windows to run it
I am updating this post after several months in case someone else is going through the same issue. It turns out that the problem I had was that the processor was too tightly secured to the motherboard, somehow preventing it from making contact with the dual-channel modules. I followed a Reddit post where they encountered the same issue with a different laptop brand, and what they did was loosen the processor a bit (or vice versa, according to other users), and the problem was resolved.
Now, I am enjoying 32GB in dual channel, and I hope this information can be helpful to someone in the future who might be experiencing a similar issue. Regards!

No. DDR4 won't fit into a DDR3 socket, much less work electrically.

Welcome to the Dell Community @MoosaImran
The "Notch" prevents you from using DDR4.

As stated in the other responses, your machine only works with DDR3 RAM.
Honestly for most computing tasks, you wouldn't notice any performance difference between DDR3 and DDR4.
If more RAM is your goal, the Precision M4700 can be upgraded to 32GB of DDR3 (4x8GB - 2 slots on the bottom and 2 slots under the keyboard)

@LittleJohnxxx73 In order for you to use the additional 2 slots under the keyboard is by upgrading your processor to a Quad Core processor.
Your processor is a Dual Core.
