Question Problem with RAM on old motherboard ?

[mujinfaye]

Hello,

I have an old Asus P7P55 LX motherboard and I have trouble regarding RAM.

Slots 1 and 2 are the same RAM.
Slots 3 and 4 are different.

Tried:
1. Reseating Rams.

G.SKill only works on Slot 1 and 2. -> Won't work if moved to 3 and 4.
The other two rams (KINGSTON) don't work on Slots 1 and 2. -> If used by themselves. The PC will turn on but won't boot. No Ram light.

** Note that KINGSTON RAMS work fine on my other unit (Just bought them)

2. MemOK -> Didn't do anything.
3. BIOS Reset


-- Like Pleaaaaaaaseeeee

** Issue is that only G.Skill gets recognized in BIOS. But all four are recognized by windows and cpu-z. The problem is windows tagged both Kingston as Hardware Reserve.

mixing RAM kits is not recommended.

even if they were the same exact make & model there is no guarantee that they will function together.
and even if they do it can lead to other issues with the system.

you should always verify within the motherboard compatibility lists what specific models are accepted.

So what's the issue? Everything seems to work.

You may want to increase DDR voltage. Do not go above 1.65V.

Re-edited the main post to specify the problem.

Both models are not listed on the Motherboard Manual that I found, but Surprisingly, the G.Skill works. I have no idea why the Kingston won't work even though it was recognized.

Can you show screenshots from BIOS?
Also a new screenshot from Task Manager Performance/Memory section.

Increase DRAM voltage.
1.55V, 1.6V, 1.65V.

See if, ram gets properly detected.

Still 8GB detected in BIOS. Windows and CPU Z Still detects all 4
