Corsair is running a flash sale on a high-capacity kit of Vengeance RGB Pro DDR4-3000 memory, a 64GB kit consisting of a pair of 32GB modules, normally priced at $319.99, but apply coupon code "FLASH" at checkout for only $260.99.

This discount makes it one of the least expensive 64GB kits of DDR4 memory, especially if you choose two 32GB modules (as opposed to four 16GB modules). At Newegg, for example, even 2x32GB kits of slow RAM (DDR4-2666) without heat sinks, like TeamGroup's Elite 64GB DDR4-2666, cost more, at $289.99.

Do you need this much RAM? For gaming, 16GB is generally sufficient, and 32GB is a bit extravagant. So a 64GB kit is definitely overkill for most people. The exception is if the PC is also used for RAM-consuming content creation, such as high-resolution photo editing.

Or if you have multiple Chrome tabs running (although Chrome doesn't eat much memory).

However, if you want to set up a large amount of memory, we recommend purchasing a high-capacity kit like this one on sale. Plus, this kit also comes with RGB lighting; the Vengeance RGB Pro is a nice one, and Corsair makes some of the best RAM for gaming.

It should be noted that DDR5 platforms are coming, starting with Alder Lake later this year and Zen 4 next year; TeamGroup has also started selling DDR5 memory kits ($311 for 32GB DDR5-4800). If you are looking to get by until Alder Lake and Zen 4 arrive, it doesn't make much sense to spend money on a high-capacity DDR4 memory kit.

At the same time, the pending arrival of DDR5 platforms is not necessarily a reason to avoid DDR4. Now, building a new PC (good luck finding a GPU...) or or upgrading an existing PC and hoping it will last a few years, then splurge without fear of having buyer's remorse in a few months.
