8.1 GB RAM out of 16GB showing as Hardware reserved

[Jaasskk]

So im running two different RAMs with different timings in my PC. one is 3000mhz and has timings 16-20-20-38 and other is 3200mhz and has timings 15-15-15-36. whenever i get out of the bios, i get 3 beeps twice and then a single beep and my pc boots up. in Task manager my Memory is showing 8.1GB as System reserved. what can i do to get rid of that ? do i necessarily have to get exactly similar RAM ?

Yes, you have to get the same exact RAM.

No you don't. It will all run at the speed/timings of the slower module, but they don't need to be identical.

 

@Jaasskk consult your motherboard manual to make sure you have the two (I am presuming it's two) sticks in the correct slots. Remove and reseat them in the slots.

Best thing to try is manually set everything to the lower of the 2 speeds in UEFI, so go in and force your ram to run at 3000 16-20-20-38, you'll lose a tiny bit of performance from downclocking the faster pair very slightly but it should work fine.

Sometimes a clear CMOS and a memory reseat can fix that

I know mixing speeds is mostly fine, but I've had mixed success with mixing timings.

Yeah i tried that... its actually running at the speeds of the faster module... do i need to manually change that ?

i tried removing and reseating them and i did check they are in the correct slots

i just tried that but it just beep 3 times, power cycles , does this 2 times more and then just boots up, and in CPU Z i see the timings of the Higher RAM

Specs?

 

Often if your system has an iGPU that will take some of the RAM, but 8gb is much for that. If it has an iGPU and also a GPU disable the iGPU in BIOS
