Ram performing way below expectations

Dank_8 · Jan 4, 2018

i tested my pc via userbenchmark and found out my ram is performing way below expectations

CPU: Intel Core i5-6600K - 80.5%
GPU: AMD RX 480 - 64%
HDD: Toshiba DT01ACA050 500GB - 77.3%
RAM: Corsair Vengeance LPX DDR4 2133 C13 2x4GB - 25.1%
MBD: Gigabyte GA-Z270M-D3H-CF

as you can see my ram is performing at 25% while the regular is at least 42%

i have no idea how to fix it pls help

What is the current speed of your RAM?
Sometimes MBs won't automatically run RAM at its rated speed and will drop down into compatibility mode.

how do i check?

Run CPU-Z and look at DRAM frequency.

Edit - if it says 1066Mhz then you are good on speed (1066Mhz x 2 = DDR 2133)

Use several benchmarks.
Sisoft's SANDRA is pretty good and you can compare with similar systems.

Does CPUz tell you you have all 8GB available? Does it also say that you are running in dual channel mode? Both of these can be found in the Memory tab.

RAM was bought in a kit right?

Userbenchmarks also compairs your memory to peoples that has been overclocked.
You need to go into BIOS and make sure the timings are set to the memory specks.

The lowest default speed of a Z270 board is 2133.

Zerk2012 :

True. This is the lowest 'supported' speed.
I have seen MBs POST at lower than the lowest-listed speed when going into compatibility mode though.

alceryes :

Not a Z270 board.
