Memory write speed is good.
Since DDR4 uses 8-bytes (64-bits) bus for data transfer, its maximum speed in bytes per second will be equal to eight times the number of data transfers per second. Or in other words; the maximum speed of a DDR4-3200 memory module will be 8 × 3200 million bytes per second, or 25600 MB/s.
You have it at 25595 MB/s.

Memory read speed wise, the theoretical max for 3200 Mhz is 50 GB/s. But latency also adds to that, drawing the max number down.
So, your ~45.8 GB/s seems right, when also considering latency.

Thanks for info, I have seen other ram benchmarks on userbenchmark with the same ram modules reaching 40000mb/sec at write, but on r7 5700x 5800x not on my 5600. Does ram benchmarks is done just on one stick? I have 16gb. 8 gb X 2 sticks. These are on a r9 5900x :

Userbenchmark RAM "Multi core" values are reached by:

Maximum memory throughput using multiple processor cores.

You get that pop-up when you hover over the ? mark just after "Multi core".


Also, the screen you shared, shows the all time 2nd best score for that RAM. You can not take the 0.003% percentile and imply it to be as "average" for that RAM.
That RAM results in Userbenchmark,
link: https://ram.userbenchmark.com/SpeedTest/1612519/Kingston-KF3200C16D48GX-2x8GB

Scroll down and at 1st, you'll see latest benches of that RAM. After the list of latest, click on the "36,835 MORE >>" link, to see best runs. And the screen you shared, is 2nd best bench by USA-User 4 days ago.

Main diff between your R5 5600 and their R9 5900X is cores/threads amount. They have it double over you. 12c/24t vs your 6c/12t. And since "Multi core" performance directly ties down to CPU cores/threads, they also have it better than you have it.

One more question. Why does an I5 10400f reach 40k mb/sec write speeds? it has 6 cores i think. Amd 1000 series reach 40k too. All ryzen 5600 cpus reach max 27k mb/sec. Is that a problem with 5000 series?

My old setup, Even gpu is better there: Gigabyte GA-B450 AORUS ELITE Performance Results - UserBenchmark

AMD Ryzen is far more capricious with RAM than Intel is. With this, AMD plays catch-up with BIOS updates.

It is unknown what BIOS version all the tested users use, but it's common that most people aren't updating their BIOS. Instead they use whatever BIOS MoBo came with. With AMD, that is a bit of bad idea, since AMD has to optimize the CPU with BIOS updates. For some reason AMD can not offer the same out of the box, high performance quality, as Intel does with their CPUs.

For example;
I'm running 6th gen Intel (i5-6600K) and the BIOS i have, is the one that came with MoBo. I do have newer BIOSes available but for the most part, those give my Z170 chipset MoBo support for Intel 7th gen CPU. Since i haven't had the need to upgrade my CPU for the past 7 years, i haven't had the need to update my BIOS either. More so, because my CPU is offering me the most it can and i don't have to do "optimization" updates.
For Ryzen, it is common that once new chipset launches, it is incapable of supporting faster RAM speeds than JEDEC standard (2667/2933 Mhz). Instead, users have to wait until AMD releases new BIOS update, that enables them to use e.g 3200 Mhz RAM or faster. Among other optimization features, which, IMO, should be available off the bat (as it is with Intel).

My old setup, Even gpu is better there

Could be iffy GPU driver version.

Sometimes, i've had issues with latest GPU drivers, whereby i had to revert back to older version.

Btw, GPU drivers, as such, are the ones that i haven't updated for a long while. I'm running Nvidia 516.94. Since when it isn't broke - don't fix it.

Thanks! Ryzen 5 5600 is a beast in gaming, but a little slower than intel in Windows tasks, app opening time is a little longer than with a intel cpu. Probably amd will get better in future. Intel always replace sockets, amd doesn’t do that, they made 4 generations on am4. I use a beta bios version. Have a good day! Sorry for my bad English

Intel always replace sockets, amd doesn’t do that, they made 4 generations on am4.

Intel does it's tick-tock cycle, max 2 gens per one chipset.

AMD did try to push AM4 for 4 gens but as tech advances, it is going to be more and more complicated to make the old tech (e.g Ryzen 1000 series) be compatible with latest 500-series chipset, despite sharing the same AM4 socket. Same is vice-versa, making newer Ryzen 5000 series compatible with old 300-series chipset.

Full compatibility list here: https://www.amd.com/en/products/chipsets-am4
For example;

• Ryzen 1000 series CPUs will not work with 500-series chipset, at all.
• Most of Ryzen 2000 series CPUs won't work with 500-series either. Only when you have non-G Ryzen 2000 CPU and X570 chipset MoBo, it works. Otherwise it won't.
• Same goes when you have Ryzen 3000 series with G suffix (e.g R5 3400G), it won't work with 500-series MoBos, except X570 chipset.
• But R5 3500 has 0 problems working with 500-series MoBos, be it A520, B550 or X570 chipset MoBo.
• On the flip side, Ryzen 3000 series without G suffix (e.g R5 3500) won't work with A320 chipset MoBo. And works with B350 and X370 with select beta BIOSes.

So, overall, there is no universal support from Ryzen 1000 to 5000 CPUs and 300-series to 500-series chipsets. Only B450 and X470 chipsets support all 5 gens of Ryzen CPUs. The rest have sporadic support.

With Intel, you do not have to go and figure out which chipsets, within the same series, work with which CPU.
E.g 100-series chipsets (H110, H150, B150, H170, Z170) work with ALL 6th gen CPUs (Skylake), be it Celeron, Pentium, Core i3, Core i5 or Core i7. And with latest BIOS update, all 100-series chipset support ALL 7th gen CPUs (Kaby Lake). Intel does not fiddle around, by dropping support to cheaper chipsets, while giving support only for high-end chipset, like AMD has done it.
