The Best RAM for Your PC (2025)

DDR4 vs DDR5

There are at present two requirements available on the market, and there in all probability will proceed to be for some time as DDR4 phases out. Likelihood is, in the event you’re upgrading an older system, you’ll want DDR4 RAM, and in the event you’re constructing a brand new system, you’ll be in search of DDR5. Test your motherboard mannequin to ensure, as a result of they aren’t appropriate with one another. You can too try an in-depth explainer on the differences between DDR4 and DDR5 in the event you’re curious.

Capability

As soon as you recognize whether or not you want DDR4 or DDR5, the following main resolution is how a lot reminiscence you need. Until you actually plan on simply looking the net and watching the occasional video, I like to recommend beginning at 32GB. Most reminiscence is offered in kits, so if you’d like 32GB you’ll sometimes purchase a pair of 16GB sticks, usually proven in listings as 2x16GB, and set up them in accordance with your motherboard’s directions for twin channel reminiscence. Some players might profit from 64GB of reminiscence, however something extra can be for particular use circumstances.

Velocity

The opposite quantity you’re prone to see prominently displayed on reminiscence is clock pace, measured in MHz. DDR5 begins at 3,200MHz, nevertheless it looks as if most DIY reminiscence falls within the 6,000-6,400MHz vary. Some fanatic RAM goes all the way in which as much as 8,000MHz, however I don’t assume the typical person will profit from that a lot pace.

Notably, if you wish to totally make the most of your RAM’s said pace, you’ll want to ensure XMP, or AMD’s EXPO, are enabled in your BIOS. Test your motherboard handbook for extra info on enabling the function and setting your MHz correctly.

Latency

Efficiency has one other measurable operate within the type of CL, or CAS Latency. Whereas the clock pace measures how briskly the RAM can transfer information, the CL denotes how shortly it could actually entry that information, with a decrease quantity that means quicker entry. Whereas clock speeds received an enormous bump with DDR5, the CL numbers may look excessive to of us who’ve expertise with DDR4. Simply know that the upper clock speeds make up for this distinction, so now we’re taking a look at 28-30 for the primary quantity as an alternative of the 12-16 we had earlier than.

Match and Compatibility

There are just a few issues you additionally might want to bear in mind when buying reminiscence on your system. Most modules are roughly the identical dimension, however when you’ve got a big CPU cooler chances are you’ll wish to make sure that any shrouds on the reminiscence aren’t too tall. Most DIY motherboards don’t have capability limits for reminiscence that ought to concern your common PC person, and even gamer, however in the event you’re upgrading an older system, you’ll wish to verify the handbook and motherboard mannequin to substantiate how a lot storage it could actually deal with.

Know that there are sometimes two sizes of reminiscence module. You’ll often discover DIMMs in desktop computer systems, and SO-DIMMs in laptops, however some very small desktop computer systems might go for laptop computer reminiscence.
