Best RAM for Gaming: Top Picks and Live Prices

Which gaming RAM should you buy?

Short answer: for a new gaming PC, buy 32GB of DDR5 as a kit of two 16GB sticks. Current platforms such as AMD AM5 and Intel Core Ultra 200S only take DDR5. If your PC has a DDR4 motherboard, stay on DDR4 and add capacity instead.

We do not test RAM in a lab, so these are not reviews of single products. We compare kit types on their specifications and on price. The table pairs each kit type with the gaming PC it suits and shows the lowest price we found this week in UK shops.

Prices are including VAT, checked on 2 November 2026. Every kit in each class, with the shops side by side, is on our 32GB RAM prices and DDR5 RAM prices pages.

What RAM size is right for gaming?

For most players, 32GB. RAM is the fast working space your PC fills with the game and everything else you have open, so the amount matters more than the label on the box. Newegg splits needs into three rough tiers. 16GB covers browsing, office work, school work and most gaming at 1080p. 32GB is for gaming with a browser and chat open, photo editing, light video work and the odd virtual machine. 64GB only pays off for serious video editing, 3D rendering, large datasets or local AI models.

The Steam Hardware Survey points the same way. In September 2026, 32GB was the most common amount of system RAM among Steam users, at 42.22%. For a fuller breakdown by use, see how much RAM you need.

16GB still works for gaming, especially on a budget build. The margin gets thin once Discord, a browser and recording software run next to the game. This week the cheapest 16GB DDR5 kit costs £184.99 and the cheapest 64GB DDR5 kit £729.95. Our 16GB RAM prices and 64GB RAM prices pages list every kit.

How the capacity is made up counts too. Mainstream desktop platforms are dual channel, so two sticks give you the full bandwidth. Newegg advises a matched kit such as 2 x 16GB rather than two sticks bought separately.

Does faster RAM help in games?

Less than the marketing suggests. Engadget notes that no game needs a particular DDR5 speed: anything that runs on DDR5 runs fine on the slowest DDR5-4800 kits. Going from the slowest kit to a mid range one may add a little performance. According to Engadget, DDR5-7200 and DDR5-8400 kits only marginally raise frame rates in CPU bound games, and they cost a lot more.

Speed is given in MT/s and latency as CL, a number of clock cycles. A higher CL is not automatically slower, because the clock speed goes up with it. To compare kits, convert to nanoseconds: CL x 2000 divided by the speed in MT/s. That puts DDR5-6000 CL30 at 10 ns, the same as DDR4-3200 CL16, while a DDR5-4800 CL40 kit sits at nearly 17 ns according to Engadget. Crucial adds that at equal latency in nanoseconds, the faster kit wins. Our guide to RAM speed and latency explains the maths in more detail.

The table below sets the common 32GB DDR5 speeds side by side with the lowest price we found this week.

So DDR5-6000 CL30 is often better value for a gaming PC than a pricier 7200 MT/s kit. Every kit in that class is on our DDR5-6000 CL30 page.

Best gaming RAM for AMD AM5 and Intel

On AM5 with a Ryzen 7000 or 9000 chip, buying guides usually point to DDR5-6000 CL30. AMD itself guarantees less: DDR5-5600 for Ryzen 9000 and DDR5-5200 for Ryzen 7000. Engadget says almost every AMD build still uses a DDR5-6000 kit. The memory controller can run at the same clock as the memory up to roughly 3,000 MHz; above that it drops to half the memory clock, which adds delay. Engadget cites Tom's Hardware results in which DDR5-6000 CL30 finished ahead of a DDR5-6400 CL32 kit.

On Intel, Core Ultra 200S processors only take DDR5, officially up to 6400 MT/s. Engadget adds that DDR5-6400 applies to CUDIMMs, modules with their own clock driver, while regular sticks are rated at DDR5-5600. Newegg recommends DDR5-6000 to 6400 for these builds. Intel 12th to 14th gen Core chips come on both DDR4 and DDR5 boards, so there the motherboard decides.

Stick to two sticks rather than four. For the Ryzen 7 9800X3D, AMD lists DDR5-5600 with two modules but only DDR5-3600 with four. If you want 64GB, a 2 x 32GB kit is the better buy than 4 x 16GB.

Gaming RAM by brand: which lines to look at

Brand matters less than the specs printed on the kit, but the big lines differ in height, lighting and profiles. These are the main desktop DDR5 gaming lines, as their makers describe them, with the lowest 32GB DDR5 price per brand this week.

Look closely at the CL rating within a line. G.Skill's 32GB DDR5-6000 Ripjaws S5 kit is rated CL36, against CL30 for its Flare X5 kit at the same speed. A low module height also helps if you run a large CPU air cooler. Corsair and G.Skill both note that their kits boot at a lower default speed and need the XMP or EXPO profile switched on to reach the rated speed. Our Corsair RAM prices and Kingston FURY prices pages track each brand.

Upgrading a DDR4 gaming PC

DDR4 and DDR5 do not fit the same slot, because the notch sits in a different place. A DDR4 motherboard only takes DDR4, whatever the CPU. The typical upgrade for a DDR4 gaming PC is going from 2 x 8GB to 2 x 16GB of DDR4-3200. The cheapest 32GB DDR4 desktop kit costs £174.99 this week.

If your RAM fills up while you play, a bigger DDR4 kit fixes that and the board and CPU stay where they are. Moving to DDR5 is really a decision to buy a new platform, not a memory upgrade. Every DDR4 kit we track is on our DDR4 RAM prices page, and the basics are in our guide to what RAM is.

What we do not know yet

We measure prices, not frame rates. Our data cannot tell you how big the gap between two kits is in a given game. For that we point to the sources above, and even there the result depends heavily on the CPU, the graphics card and the resolution.

We also do not know where gaming kit prices go in the coming weeks. Our UK price series is still young. Change in the median price per GB over 4 weeks: not measured yet. Change since 13 October 2026: not measured yet. Once enough weeks are in, these lines will show firm figures.

Common mistakes

• A DDR5 kit for a DDR4 board. The sticks will not physically fit. Check the motherboard manual before you compare prices.
• Forgetting the BIOS profile. Without XMP or EXPO, a DDR5-6000 kit stays at its default speed, so you pay for speed you do not use.
• Adding two more sticks later. Four sticks on two channels pull the speed down, as AMD's figures for the Ryzen 7 9800X3D show. Buy the right two stick kit from the start.
• Ordering laptop memory for a desktop. SO-DIMM is the small format for laptops and small form factor PCs and does not fit a desktop slot. Laptop kits are on our laptop RAM page.
• Paying for the fastest kit to chase FPS. Engadget found that very fast kits add little in CPU bound games. If your memory fills up while gaming, more capacity helps more than more speed.
