MSI B350 Tomahawk / AMD ?

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

I task man it shows my speed at 1067 can i get some help with my speed
It should be as simple as enabling X.M.P in BIOS.

According to where you are looking and with what the 2133 and 1067 numbers are actually representing the actual (speed) value. "dual data rate" remember.

Go into the motherboard settings and see what 'XMP' options are available to you. First gen were not known to be able to run beyond around 2400 and I never had one run better than around 3K no matter what tuning I tried. YMMV.

Actual speed is 2133MHz because memory is DDR (Double Data Rate)

im not able to get past 2133

1st gen Ryzen + b350 MB is troublesome combo for fast RAM. 2933-.3000MHz is just about maximum expected. If there's no XMP profile for those frequencies, you will have to tune it manually.
This can help

I have the preset for the speeds from a-xmp but will not take them

First gen Ryzen was really picky with XMP and RAM speeds above 2933. I would not use XMP, manually set the speed to 2933, and see if it boots with that. If it does, then i would tweak the rest of the settings. Personally, id just leave it at 2933 with default settings if it works.

DRAM Calculator for Ryzen v1.7.3 Download

DRAM Calculator for Ryzen helps with overclocking your memory on the AMD Ryzen platform. It suggests stable memory timing sets optimized for your m

Use this to calculate values, print it or write values down and change to those in BIOS. Make sure you know how to reset CMOS in case those changes do not work.
XMP is just a set of instructions to BIOS written in the RAM modules to make settings appropriate to particular memory, in essence to overclock it and memory controller in the CPU. If it doesn't you have to do it manually. If you can't than we can't help from distance.
PS. Which BIOS version and is it updated ?

I couldn't get my Ryzen 2600X to boot with a pair of DIMMs rated at 3,000MT/s. The 2600X is specified by AMD up to 2933MT/s and it refused to work with the default XMP 3,000 timings in the SPD chips on my RAM.

The solution was simple. I selected XMP 3,000, then manually adjusted the CL/CAS timing from CL=16 to CL=18. This raised the Column Access Strobe (CAS) delay from 16 clock cycles to 18 clock cycles. At CL=18, my 3.000MT/s RAM is stable.

Check the CL(CAS) speed of your RAM and increase the setting by 2. for example, if your RAM is CL=18 at 3200MT/s, increase it to CL=20. If it's CL=20 at 3,200MT/s, set it to CL=22.

If increasing the CL value by 2 doesn't work, try adding 3 to the setting. More clock cycles = longer delays = slower memory, but can result in more stable RAM.

Make the changes on all DIMMs installed, save the settings and reboot. If you're lucky, you might get your CPU to run at 3,200MT/s.

If you cannot achieve stability at XMP 3,200, try reducing the speed to XMP 3,000 and add 2 to the CL(CAS) settings.

When you think you've achieved stability, run a full MemTest86 suite of tests (several hours). If you get even one error in MemTest86, your RAM isn't stable. Carry on tweaking the timings.

N.B. The default JEDEC speed for your RAM is probably 1,067MHz (true clock speed). Since you're using DDR (Double Data Rate) RAM, the memory is usually specified as DDR4-2133, also known as 2,133MT/s (Mega Transfers per second).

The real memory clock frequency is 1067MHz (JEDEC), but DDR means data is transferred on both the positive going (rising) and the negative going (falling) edges of the clock waveform, so the RAM appears to be running at twice the true clock rate.

Hence 2 x 1,067MHz = 2,133MT/s.

Most people use the DDR number, but programs like Aida64 and some BIOS display true RAM clock frequencies, which are half the DDR rate. This can be confusing at first, as can JEDEC and XMP.

DDR4-3200 has a true clock frequency of 1,600MHz, but a DDR rate of 3,200MT/s.
