facing ram speed issue

I've recently changed my 2400mhz Corsair ram to 3000mhz Corsair ram, Everything swapped and installed fresh windows 10 1903, My ram speed is showing 2133mhz in task manager, So I've upgraded my bios and enabled xmp and the ram speed is changed to 2933 mhz in bios and it's showing 1457mhz in taskmanager and any other app, I used some ram benchmark tools and it says "Corsair 2900mhz clocked at 1457mhz" My ryzen 3 1300x processor only supports upto 2667mhz so it couldn't be running at 2900mhz , I previously used 2400 mhz stick and it worked perfectly it showed 2400mhz in task manager and every where but I'm facing issue with this, My specs are R3 1300x Msi b450 tomahawk Mobo 8gig Corsair 3000mhz 120gig ssd Please help me.

my gaming performance has also been decreased

Re: facing ram speed issue

Memory clock and memory speed are two different measurements. Memory clock of, say, 1600mhz equals an effective memory speed (as it's DDR, Double Data Rate) of 3200mhz.

Re: facing ram speed issue

chanu_9873, I did not even know that the task manager showed the memory speed.  Obviously it does not know how to do that and your beef is with MS to get it fixed.  Please post a screenshot of Ryzen Master (RM) - simply drag-n-drop the image into your reply.  Did it occur to you that 1457 is really close to half of 2900?  The memory clock is actually half of the memory speed.  DDR means Double Data Rate and in DDR data is transferred on the up transition as well as the down transition.  RM will show the Memory Clock - it will be half the Memory Speed.  Enjoy, John.

Re: facing ram speed issue

i know the memory clock is half the total speed cuz of ddr,

but i have three doubts here

1. my previous ram 2400mhz one showed 2400mhz in task manager but this shows only half

2.after searching online ive seen that the maximum ram frequency r3 1300x could support is 2667mhz but mine running at 2933mhz how?

3.my gaming performance has been decreased compared to my previous 2400mhz ram ive lost like 10-12 fps

amd ryzen master says memory clock is 1457mhz and ive checked in command prompt its shows 2993mhz 

and userbenchmark says "8gb dimm ddr4 2933mhz clocked at 1457mhz"ive attached the photo

thanks for your time and help please check theseAnnotation 2019-06-07 204917.png

Re: facing ram speed issue

From MSI Support showing your motherboard's Spec: Specification for B450 TOMAHAWK | Motherboard - The world leader in motherboard design | MSI Global 

I see only one Corsair RAM MEMORY at 3000 Mhz listed for your Ryzen 1xxx Processor. Is this the one you have installed? The Motherboard Supported Speed is 2933 Mhz.

If it isn't it is possible that the RAM is not fully compatible with the motherboard or Processor.

I would remove all the RAM Module installed EXCEPT one and see if it shows correctly. I would do this with all the RAM Modules. Possibly one is defective.

You might want to run MEMTEST86 and see if any errors shows up. If they do remove all but one to find out which RAM is showing the error(s).

Re: facing ram speed issue

chanu_9873, again, I say if you do not like what MS says about RAM speed, talk to them.

Please DO NOT believe everything you read on the Internet!  You have read nonsense.  The maximum RAM speed is just that.  If the user wants to spend the time to tune the RAM, the sky may be the maximum.  A user posted the other day that he had some memory running over 4000 MHz.  Play with it if you like but DO NOT believe everything on the Internet.  userbenchmark  got it correct!  It also said 1 of 4 slots occupied.  You realize your machine has dual memory channels.  With only one stick, you have given up 50% of you memory data rate.  If you really believe your gaming performance is lower, chase that problem and get a DUAL channel memory kit.  Enjoy, John.

Re: facing ram speed issue

I only have one ram module and it is this,

What should I do now I'll run memtest 86 and see any errors pop up,

Thank you.

Re: facing ram speed issue

Well I couldn't buy an another stick anywhere in the near feature cuz I spent my money on this ram and new tomahawk Mobo,

Are there any alternatives to fix my ram speeds or any place I could do more research and fix this,

Thank you.

Re: facing ram speed issue

Yeah, noticed that you only have one RAM installed after I reread your original post.

Is your Ram listed on MSI Motherboard's QVL List?

There is no harm running MEMTEST86. At least it will eliminate obviously defective RAM. But the RAM can pass with flying colors but not still be fully compatible with your Processor or Motherboard.

The reason why your original 2400 Mhz RAM ran at 2400 Mhz is because in the QVL List it shows that it will run at 2400 Mhz. But the RAM you have now, even thought it is 3000 Mhz, the Motherboard will only support 2933 Mhz which is what you are seeing. Unless you use XMP Profiles to overclock the RAM automatically in BIOS.

If you notice your computer becomes unstable or crashes or doesn't boot after enabling XMP, then just do a Clear CMOS (remove Motherboard Battery) to put BIOS back into "default" or go into BIOS and click on putting BIOS back into "Default" Settings.

You mentioned you installed the latest NON-BETA BIOS for your Motherboard. So an BIOS update won't change anything. You should also update your Motherboard's CHIP Set to the latest.

Otherwise it is a good chance your RAM may not be fully compatible with the Motherboard or Processor. If it is listed, then I would contact MSI Support and see what they recommend.

Otherwise I am out of suggestions.

Good Luck!

Re: facing ram speed issue

chanu_9873, you could buy another identical stick and it would probably work.  It is always better to buy a matched kit, but many have done two singles with success.  I do not know what you mean by this:"Are there any alternatives to fix my ram speeds or any place I could do more research and fix this".   Except for the dual channel problem, you have not identified any memory or speed problem.  You have showed only that some applications report memory speed/clock correctly and others do not.  If you really think your performance is less now than before, please post some evidence and we will try to help you - do not know what you want to research, so cannot suggest anything.  Enjoy, John.
