Is this normal for DDR3?

I was wondering cause I saw the DDR5-4800 speeds are like 38 GBs. I saw mine at 40 GBs and was like what???

Here's mine by way of comparison. ECC Registered as I run a workstation.

I am some similar RAM, let me run this and post my results.

Hold Please!

Normal is Subjective. DDR3 1600 in QuadCH.
Quad channel isn't typical for most systems on DDR3 (Dualchannel) is the norm mainstream setup.
x79-x99 and HEDT platforms use Quad channel, less mainstream though.

EG My 2133Mhz Dualchannel kit does 33GB/s Read, 31GB/s Write and 30GB/s Copy (I'd post my screens, but currently PC is actively rendering)

Maximums - Asus Z97-K /w i5 4690 Bclk @106.9Mhz * x39 = 4.17Ghz, 8GB of 2600Mhz DDR3,.. Gigabyte GTX970 G1-Gaming @ 1550Mhz

What exactly are you asking?

 

You have Dual Channel DDR3-1547 on each CPU, because of your overclock.

 

By the way, many people would love to own that motherboard. Take care of it.

Main: AMD Ryzen 7 1700X, Nvidia GTX 780, 16 GB 2667 MT/s DDR4 Fedora 33 x86_64

Secondary: Intel Xeon X5670, Nvidia GTX 660, 24 GB 1333 MT/s DDR3 Windows 10 Home x86_64

Server: Intel Xeon X5670, 60 GB 1333 MT/s DDR3-R Ubuntu Server 20.04.1 LTS x86_64

Laptop: Intel Core i5-3320M, 16 GB 1600 MT/s DDR3 Fedora 32 x86_64

You could pump that number up further by getting the two other channels involved, for a Hex-Channel operation.

 

Practically, it isn't as good as true "quad channel" due to the CPU-CPU latency.

Theoretical bandwidth I remember and scale from dual channel 3200 runs to about 50GB/s (doesn't matter DDR generation, although for DDR5 we should talk per-module due to configuration changes). It scales with channels, it scales with speed, so both have to be taken into consideration. It should further be noted that the practical bandwidth as measured by tools will be lower than the maximum possible.
