Targeted DDR3 upgrade

This 8 GB kit delivers two 4 GB DDR3 1600 modules built specifically for the Acer Predator AG3-605-UR2E, AG3-605-UR3B and AG3-605-UR1A desktops. It suits owners of those systems who need a straightforward capacity increase without compatibility guesswork. Builders working on other platforms or requiring ECC or registered memory should look elsewhere.

240-pin unbuffered DIMMs

Each stick uses the standard 240-pin DDR3 form factor at 1.5 V with CL11 11-11-11 timings and a 2Rx8 organisation. The modules are unbuffered and non-ECC, matching the native slot specification of the listed Predator models. No heat spreaders are fitted, so clearance inside compact chassis remains unchanged.

Two-module kit only

The package contains exactly two memory sticks and no additional cables, tools or software utilities. Installation is limited to seating the DIMMs in the available slots; no driver or firmware steps are required. Users needing a single 8 GB module or a four-stick population must source a different kit.

Questions about this item

What speed does the PC3 12800 rating actually deliver?

The kit runs at 1600 MHz, which is the standard data rate for PC3 12800 DDR3 memory.

Will these 240-pin DIMMs fit the four slots on my Acer Predator AG3-605 motherboard?

Yes, each module uses the standard 240-pin DDR3 DIMM form factor that matches the board's memory sockets.

Do I need to enable XMP in BIOS for the CL11 11-11-11 timings to apply?

DDR3 1600 CL11 is a JEDEC standard speed; the modules will operate at those timings at 1.5 V without any XMP profile.
