Question My mobo uses 2400mhz even though ram is 3200mhz

[Nahboys]

I have an ASrock b450m steel legend mobo and 16x2 of Kingstone 3200mhz of ram but today I realized in the task manager that my pc uses 2400mhz so I went into the bios and changed it to 3200mhz in oc section which was set to 2400mhz as auto . Will my pc now malfunction cause of this or anything ????

Task Manager is not a proper way to check ram speed.
Use CPU-Z instead.

Will my pc now malfunction cause of this or anything ????

You're overclocking your ram now.
Ram overclocking is not guarantied. You have to test overclock stability.

If overclock is not stable, then yes - you may experience malfunction.
Manual tuning of ram parameters may be necessary.

How do I test overclock stability and why would my bios set my ram MHz to 2400mhz by default ?
And how do I check ram ram speed in CPU-Z ?

How do I test overclock stability

Boot into windows,
test, if it is stable,
run some memory benchmarks,
boot with memtest86 and test your ram,

and why would my bios set my ram MHz to 2400mhz by default ?

Probably because that's default ram frequency, your cpu can use without ram overclocking.
What model cpu are you using?

And how do I check ram ram speed in CPU-Z ?

Look in CPU-Z - memory and spd tabs.
All the info is there.

 

[Nahboys]

What model cpu are you using?

I am using AMD Ryzen 7 5700G

 

[SkyNetRising]

Ryzen 7 5700G should be able to use 3200mhz ram without overclocking.

Your ram probably doesn't have spd entries for 3200mhz mode.
And that's why 3200mhz mode requires use of A-XMP/DOCP.

Can you show screenshot sfrom CPU-Z - memory and spd sections?

Spd tab and memory tab.

Your ram is running at 3200mhz ( =1596.9 x2 ).

But your ram modules are in wrong ram slots.
Therefore you can not activate dual channel mode.
This hurts performance.

is it cause I went into the bios and selected it on 3200mh so now its showing 3200mhz ?

 

[Nahboys]

But you have only single ram module.

what does that mean ?

 

[Nahboys]

Therefore you can not activate dual channel mode.

Is there any way I can activate it if so how

Yes. Sure.

Put ram modules in correct ram slots.
Slots - A2 and B2 (2nd and 4th counting from cpu).

I cant buy a new pare of ram's now
Will overclocking do anything to my pc It's not like I do much thing with it I am only overclocking the ram right and beside I only have 5700G an APU I only play games like nfs and forza 4 battlefield 5 CSGOI am not doing vid editing with it and my fps became real good after changing it to 3200mhz

 

[Nahboys]

Your ram modules are in wrong slots.

so the reason my mobo bios took them as 2400mhz is cause they are not it pair right

No. Your ram modules have highest SPD entry for 2400mhz.
They do not have spd entry for 3200mhz mode.
But they have 3200mhz mode as xmp profile.
Therefore use of 3200mhz mode requires overclocking (or activating A-XMP/DOCP).

Did you buy them as separate modules or as a dual channel kit (sold together in single package) ?

 

[Nahboys]

Did you buy them as separate modules or as a dual channel kit (sold together) ?

Nah they are not pair the seller did told me that
they were sold in individual packet

 

[Nahboys]

Can I use stress cpu in CPU z bench tab for stability check ?

 

[SkyNetRising]

Can I use stress cpu in CPU z bench tab for stability check ?

Sure.
But that is cpu test (not ram test).

Did you manage to put ram modules in proper ram slots yet?

 

[Nahboys]

Did you manage to put ram modules in proper ram slots yet?

Wait should I I have 4 ram slots and I only first two slots are in use should I like put one ram in number 3 slot ?

 

[Nahboys]

But that is cpu test (not ram test).

then name an nice good easy ram speed tester please

Please read user manual of your motherboard.

Dual channel mode requires ram modules to be installed in slots A2 and B2 (2nd and 4th counting from cpu).

So my performance will increase If I do that and my bios will put 3200mhz as default mhz in the bios right ? and wont put it in XMP
