Question New ram cards no display, old ram shows display

May 9, 2020
Hi Sorry if this is a super long post but I wanted to detail everything if I miss something just ask, I’m not familiar with hardware
So I’ll try my best to answer.

I decided to buy more ram for my computer its running a

MSI X99S Sli plus Motherboard -
GeForce GTX 750 Graphics Card -
I7 processor (It might be 5 or 7 can’t remember but can check if needed)
Windows 7 OS

With current ram being;
Two 4g DDR4 ram cards
Specs: G-Skill Ripjaw 2400C15S-4GRR
DDR4-2400 CL15-15-35 1.20V
PC4-19200 4Gx1 Intel XMP 2.0 Ready
(Some info might be useless but wanted to provide as much as I can.)
They are inside Slot-1 and Slot 3.

I checked my motherboard manual and it said it would run 3200, I checked my
BIOS and overclock option and found my max frequency was 2666. I also found it
Supports Quad ram. I assume I can update the bios to meet that speed but would prefer
To keep it at its current version unless required.

I bought two new ram cards
G-Skill Trident 8g
F4-2400C 15D-15 GTZR
DDR4-2400 CL 15-15-15-35 1.20v
8Gx2 Intel XMP 2.0 Ready
I wanted to install them in Slot 7 and Slot 5 to match the Quad-channel-mode from the motherboard manual.
It possible I wanted to install two more ram cards but want these to work first.

I tried to keep my old ram and new ram with the same specs such as the speeds, CAS and voltage.

The issue I am having is my PC will turn on and pass a bios check if my old ram is inside, but
anytime I use my new ram my PC does not pass bios nor will it sound any beep codes, all it does is run with fans
And everything else after about 2-3 mins it will shut off reboot and stay and a stand-still until I power it off
I can remove the new ram and boot the PC without issue by using the old ram.

I've tried switching the ram cards around to test out different channels, switching both the old and new ram.

I've tried using the old and new cards on the same channel.

I've tied only using the new Ram cards with no luck,

I read somewhere that restarting the CMOS battery could help tied it and no luck, (I later used my old ram to correct the time and date)

I've tried using both sticks together and single testing them in each slot.

I've tested all slots with my old ram and have had my PC boot without issue, therefore I know the slots are working.

I've attempted to ensure they are always inside the slot as much as I can push without fear of breaking them. (The Lights on the new ram cards do come on, so I know it’s getting power to them.)

Did I miss an important detail when buying the new ram?
any help would be amazing thanks.
