The primary laptop computer with LPCAMM2 reminiscence is lastly right here. The folks at iFixit acquired their arms on the Lenovo ThinkPad P1 (Gen 7), which makes use of LPDDR5X reminiscence in an LPCAMM2 module that you could improve or exchange by merely unscrewing from the laptop computer’s motherboard.

That’s a serious change from current LPDDR reminiscence in most fashionable laptops. This sort of reminiscence is usually soldered onto the motherboard, making it far more troublesome to improve. LPCAMM2 — or Low-Energy Compression-Connected Reminiscence Module — affords modularity with out shedding the facility effectivity of LPDDR.

Conventional DDR RAM makes use of SODIMM sticks that slot into the motherboard, very like on desktop PCs. As identified by iFixit, LPDDR is far more power-efficient, but it surely must be soldered on to the mainboard, as near the processor as doable. Up till now, producers have had to decide on between upgradeable RAM and power-efficient RAM. LPCAMM2 makes an attempt to separate the distinction by cozying as much as the motherboard with screws, slightly than solder. And in contrast to SODIMM sticks, every LPCAMM2 module is dual-channel, so that you solely want one, not two.

As proven within the hands-on video posted by iFixit, you possibly can exchange the LPCAMM2 in Lenovo’s new ThinkPad P1 by eradicating the laptop computer’s backing after which taking out the battery. From there, you possibly can take out the LPCAMM2 by eradicating three Phillips-head screws.
