Is my memory defined correctly in my motherboard? I thought it was 2400mHz memory but bios say 1600mHz?

[NeilF]

So I have an old Asus Z97-A mother board with 16GB of PC3-2400MHz = Kingston HyperX Savage Red 16GB (2x8GB) DDR3 PC3-19200C11 2400MHz Dual Channel Kit (HX324C11SRK2/16)

When I look in my bios it says the memory frequency is 1600mhz? I can also see in my bios settings I can change it from AUTO and manually select DDR3-2400Mhz?

So is my memory running at the right speed or not?

It's running at 1600mhz , set it to 2400mhz but be prepared to tinker if it's not stable.

enable xmp

That's interesting... Can't see any XMP in the bios menus. But looking at the manual, there is a switch on the motherboard:-

Not sure if it's it's current 'down' position (like the picture) that's supose to on or off though

EDIT:

i think up is the enabled position

That switch was down, now it is up, and light came on next to it.

Now:-

Does this mean for FIVE+ YEARS my memory has never been running at full speed? LOL!

there we go
1200x2 = 2400

and yes, for 5 years you were at jedec standard

Where's that meme for a double face palm when you need it

Wonder how much difference it'll make to those games that are struggling a bit on my old system

Haswell Real World Performance: DDR3-1600 is Not Enough

The prevailing wisdom in the enthusiast community has been, for generations, that DDR3-1600 is the sweet spot and that faster memory offers at best extremely limited performance improvement and that at worst, it’s snake oil. There’s an element of truth to that; AMD’s Bulldozer architecture and it...

Well it's increased my CoD:MW2 frame rate I recon by 15-20%! - https://forums.overclockers.co.uk/t...-ish-gpu-on-an-old-cpu.18979699/post-36760239

BTW! It's been wrong since I built the system NINE YEARS ago

Yes. 5 years of your RAM at a slow speed.

Look into RAM and try to understand how it works and so on.

You’ll get more out of it and understand RAM timings and so on.

Your current RAM latency settings are very slow and set to 2T command rate so you’ll see another performance boost by getting those timings down and setting the timing rate to 1T.

Do a BIOS update and google your RAM for overclocking support.

9yrs actually

I'd rather leave it set to standard. I fear overclocking it, eg: 2T->1T for what might be a few fps (from an overclocking post I read - "0.5% at most in games"), might just lead to blue screens and other risk.
