Question Can figure out if my DDR5 memory is running correctly...

[fransimon]

I ma trying to figure out if my DDR5 memory is running at the correct speed. What I am seeing in CPU-Z looks wrong. Can you confirm if this looks correct and if not have any idea what might be wrong? I bought the Hardware as a bundle from MicroCenter.

Harware

• Asus TUF B650-e mother board
• Ryzen 7 7800X3d CPU
• Flare X5 Series 32GB (2 x 16GB) DDR5-6000 PC5-48000 CL32 Dual Channel Desktop Memory Kit F5-6000J3238F16GX2-FX5.

BIOS shows

• EXPO enabled DDR5-6000 32-28-28-96-1-1.35v-1.35v (I tried EXPO I and EXPO II in advanced)
• Memory 32768 MB (DDR5 6000MHz)
• DRAM Status it shows G Skill Intl 16384 MB 4800MHz in slot A2 and B2

In CPU_Z running in windows 11

• Type DDR5
• Size 32 GBytes
• Channel # 2x32-bit
• Uncore Frequency 299.1 MHz
• DRAM Frequency as 2997.3 MHz
• FSB : DRAM 1:30
• CL 32.0 docks
• tRCD 38 docks
• tRP 38 docks
• tRAS 94 docks
• tRC 134 docks

Hey there,

Simply open up CPU-z and post the 'SPD' and 'Memory' tabs and post a picture here using imgur.

We can then tell you.

Edit: Sorry, yes, your ram is running at it's rated speed of 6000. The dram frequency is DDR (Double Data Rate) which is 2 x 2997.3 = 6000 (well technically 5994.6mhz)

Yup, as I mentioned your ram is running perfectly as expected. Nothing to worry about.

 

[Roland Of Gilead]

As above. Running exactly how you want them to run.

 

[fransimon]

Thank you, I get it now.

Cpuz in the field of describing ram speed should be labelled as MT/s not frequency, as that is what cpuz it's actually reading and it just confuses people not in the know.

Dram status in Bios is reporting default spd speed of the ram prior to expo/xmp. Kind of like an ID tag but isn't the actual effective speed. Like how processors are reported in system information in Windows, the turbo aspect is ignored and instead base speed is described. Similar thing with cpuz and DDR.

Yeah, very true. I keep it in mhz for ease of understanding sometimes, but I really should explain the two terms simultaneously.

That's not your fault, it's just a way many programs try to simplify things but doesn't quite work sometimes.

MT/s vs MHz Explained | CORSAIR

RAM speed used to be measured and expressed in megahertz (MHz). However, this measurement is now being reconsidered and could be expressed in megatransfers per second (MT/s).
