Capacity and speed

This is an 8 GB DDR3 desktop memory module rated at 1600 MT/s with a CAS latency of 11. It uses a 240-pin unbuffered DIMM layout and is organised as 2Rx8 for standard consumer platforms. The PC3-12800 designation matches the 1600 MHz data rate for straightforward identification.

Who this suits and who should look elsewhere

Builders upgrading or repairing older DDR3 systems that accept 8 GB single-rank sticks will find this module a direct fit. Buyers who need more capacity per slot, error-correcting ECC functionality, or a newer DDR generation must choose a different product.

Deciding specification

The single figure that determines compatibility is the DDR3 1600 speed with CL11 timing on a 240-pin unbuffered form factor. If the motherboard requires a different DDR generation, a different pin count, ECC support, or a lower latency bin, this module will not work.

Questions about this item

Will the CL11 latency become the bottleneck during long rendering jobs?

CL11 at 1600 MT/s gives a fixed cycle time; sustained workloads are limited by the 12800 MB/s peak bandwidth of the PC3 12800 rating.

How much heat does the 2Rx8 module produce when running 24/7?

The unbuffered 2Rx8 DDR3 1600 stick operates at standard JEDEC voltage, so heat output stays within normal DDR3 thermal limits for continuous use.

Does my motherboard need a 240-pin DDR3 slot for this stick to work?

Yes, the module is a 240-pin DDR3 DIMM; it only fits motherboards with a matching DDR3 slot.
