Biostar DDR4 upgrade kit

This 16 GB kit contains two 8 GB DDR4 DIMMs rated at 2666 MHz with CL19 timings. The modules run at 1.2 V and are unbuffered non-ECC parts built on major-brand chipsets. They are validated for Biostar boards including the B45M2, H310MHC, H310MHC2, H310MHG, Hi-Fi B350S1, TB350-BTC, TB360-BTC Expert and TB360-BTC PRO.

Matched pair for two-slot boards

The kit suits builders who want a simple capacity increase on a board with two DIMM slots and a 32 GB maximum. It is not for systems that need ECC error correction, registered modules or speeds beyond 2666 MHz. Buyers planning to fill four slots or exceed the platform limit should look elsewhere.

Drops into two 288-pin slots

Each stick occupies one 288-pin DDR4 slot and draws standard 1.2 V power without a heat spreader. The matched pair enables dual-channel operation on supported boards, leaving no spare slots on two-slot designs. A 64-bit operating system is required to address the full 16 GB.

Questions about this item

Will these 288-Pin DDR4 DIMMs fit a Biostar H310MHC motherboard with two memory slots?

Yes, the kit is listed as compatible with the H310MHC and the board has two DDR4 slots, so both 8 GB modules can be installed.

If I keep an existing 2666 MHz CL19 DDR4 stick, will this 2 x 8 GB kit run at its rated speed?

All modules will operate at the slowest installed speed; matching the same 2666 MHz CL19 timing lets the kit run at its rated 2666 MHz.

How can I verify the system sees the full 16 GB after installing the pair?

Open Task Manager or System Information in a 64-bit OS; both should report 16 GB of installed DDR4 memory.
