What causes the second slot RAM speed to display 1333 MHz?
What causes the second slot RAM speed to display 1333 MHz?
slot1 - ZION 4GB DDR3 PC1600
slot2 - Aarvex 4GB DDR3 12800U (2R - 1600Mhz)
slot 1 - 1600Mhz
slot 2 - 1333Mhz (incorrect, should be 1600Mhz...)
processor - i3 2120 {dh61ho motherboard} 3.3GHz
+ Graphics card: Palit Nvidia GeForce 210 1GB DDR3
Bios configured speed: Auto

Your RAM operates at 1333mhz.
Because your motherboard can't handle RAM overclocking, this is the highest frequency it can support.
It will never reach 1600mhz on this system with this CPU.
Verify RAM speed using CPU-Z – memory and performance tabs.

Reminder – DRAM frequency in the memory section must be doubled to obtain the actual speed. This explains how DDR technology functions.

I’d like to share a summary based on past experience.
Before, I installed AARAVEX RAM in slot 1 and ZION RAM in slot 2. After that, I encountered a blue screen error, but once I switched the ZION RAM to slot 1, everything worked properly.
However, I was unsure about the RAM speed differences. It felt like a puzzle, and I wasn’t sure if it was safe to proceed.
In CMD, this command displays the information you described. The data reflects what the BIOS recorded. The ARAXEV brand RAM DDR3 would appear at 1333 MHz because of the motherboard and processor configuration in slot 2.
What are you aiming for precisely?
The system is functioning as intended.
To achieve a 1600mhz RAM speed, you'd need to either
upgrade the CPU to an Intel Core 3rd generation (Ivy Bridge) model.
Here’s a list of Ivy Bridge CPUs:

or consider upgrading the motherboard to support RAM overclocking—options include Z68 or Z77.
One stick can handle 800 speed, while the other is limited to 666.
Observe the variation in JEDC ratings.
Ensure all RAM operates under identical speed, voltage, and timing requirements.
Adopt the lower speed as the most suitable common standard.
Because the sticks weren’t tested together, it’s fortunate they functioned at all.
For confirmation of correct operation,
Execute memtest86 or memtest86+
They launch from a USB stick without requiring Windows.
You can obtain them here:
MemTest86 - Official Site of the x86 Memory Testing Tool
MemTest86 is the original self-booting memory testing software for x86 and ARM systems. It supports both BIOS and UEFI, with the ability to boot from USB.

Memtest86+ | The Open-Source Memory Testing Tool
Memtest86+ is a sophisticated, free, open-source standalone memory tester designed for 32- and 64-bit computers (supports both UEFI and BIOS).

If you complete a full pass without any errors, your RAM should be functioning properly.
Performing additional passes occasionally may reveal problems, though it requires more time.
Unless you strongly suspect a RAM issue, this isn’t necessary.
I get the points, if I encounter a RAM issue then I'll try the RAM test method, thankfully with the knowledge I have.
