Patriot Unveils Viper Xtreme 5 CKD, and First DRAMless Gen 5 SSD to Hit 14GB/s
Patriot Memory brought an updated line of M.2 Gen 5 NVMe SSDs, and PC overclocking memory products that leverage CKD (client clock driver) technology to achieve high data rates. We begin our tour with the company's flagship OC memory, the Viper Xtreme 5 CKD. Patriot set up a demo build showing off a 48 GB (2x 24 GB) kit doing DDR5-9600 at 46-58-58-154; with the Core Ultra 9 285K running in Gear 4 mode. The memory OC is y-Cruncher stable, both for versions 0.8.5 and Pi-1b. It may come as a surprise, but Patriot Memory has been around for a while in the market. In 2025, the company is celebrating its 40th year in business. All memory products and packaging have a special "40 Years" logo. The Viper Xtreme 5 CKD comes in RGB and non-RGB variants.
Besides Viper Xtreme 5 series, the company unveiled other, more cost-effective CKDIMMs, such as the Signature series CKD. These are bare modules that lack heatspreaders. The CKD helps these modules offer speeds of up to DDR5-6400. Switching gears to non-volatile memory, and we have what is probably the most interesting SSD we've come across this CES—the Patriot Viper PV563. This drive lacks any heatsink or heat spreader, and looks like it belongs in the entry-mainstream market segment, but don't be fooled by its looks. It is the first M.2 NVMe Gen 5 SSD with a DRAMless controller to claim sequential speeds of up to 14 GB/s. Gen 5 drives with DRAMless controllers such as the Phison E31T tend to offer speeds of up to 12 GB/s, but the PV563 uses a Maxiotek MAP1806 the fastest market rival to the E31T.
