Buying Guide
The Best RAM for Overclocking
Five memory kits ranked on CAS latency and rated speed; the Vengeance 16GB is the cheapest route in.
By The PC Journal editorial team
12 min read5 products evaluated
Overclocking-friendly kits ship with high speeds or tight timings and good heat spreaders. Every pick is 6,400MT/s or faster or DDR5 CL30, ordered by speed.
We ranked these memory kits on CAS latency, rated speed and capacity using manufacturer specifications; where a maker leaves out CAS latency, we say so rather than guess, since we have not benched them.

Kingston FURY Renegade RGB 32GB (2x16GB) DDR5-7200 CL38 on Amazon (opens in a new tab)
FURY Renegade 7200 offers 7200MT/s at CL38 with XMP, for Intel boards that support high memory speeds.
Best for
- Buyers who want Kingston's infrared RGB syncing.
Skip if
- Skip it if this is a deal-breaker for you: xMP profile only, so AM5 boards may need manual timings.
Why we like it
Its CL38 CAS latency is the loosest in this group; the Viper Elite 5 leads at CL30. It matches the Delta RGB 7200 on rated speed (7200MT/s). On capacity it ties with the Delta RGB 7200, the Viper Elite 5 and the Viper Venom 32GB at 32GB (2 sticks).
It shares XMP profiles with the Delta RGB 7200; the Vengeance 16GB goes with EXPO and XMP profiles. It also offers Kingston's infrared RGB syncing. Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed.
It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots. RGB heatspreaders are taller than plain ones, so check the clearance under a large tower cooler. It was priced above the Viper Venom 32GB and below the Delta RGB 7200 at the time of writing.

What to Look for in an RAM for Overclocking
Key buying criteria so you get the right fit the first time.
Rated speed
Here rated speed runs from 6000MT/s on the Viper Venom 32GB to 7200MT/s on the FURY Renegade 7200. Start with the FURY Renegade 7200 if rated speed decides it.
Capacity across these picks
Here capacity runs from 16GB (2 sticks) on the Vengeance 16GB to 32GB (2 sticks) on the FURY Renegade 7200. The FURY Renegade 7200 is the pick for capacity.
How much CAS latency you need
Here CAS latency runs from CL38 on the FURY Renegade 7200 to CL30 on the Viper Elite 5. Start with the Viper Elite 5 if CAS latency decides it. No figure for the Vengeance 16GB.
RGB
The FURY Renegade 7200 and the Delta RGB 7200 have it. Settle this first, then compare prices.
Fit and compatibility
