Fastest Timing1 of 6
TEAMGROUP T-Force Delta RGB 32GB (2x16GB) DDR5-7200 CL34 on Amazon (opens in a new tab)
The Delta RGB 7200 kit offers 7200MT/s at CL34 with XMP, the fastest pairing of speed and timing here.
Best for
- Z790 boards that support 7200MT/s.
Skip if
- Look at the others if this bothers you: xMP profile only, so AM5 boards may need manual timings.
Why we like it
Its CL34 CAS latency ranks fifth of 6 here, behind the Vengeance 64GB (CL30) and ahead of the FURY Renegade 7200 (CL38). It matches the FURY Renegade 7200 on rated speed (7200MT/s). On capacity it ties with the FURY Renegade 7200, the Crucial Pro 6400 and the FURY Renegade RGB at 32GB (2 sticks).
It also offers SK Hynix A-die memory and XMP 3.0 tuning for Intel 600 and 700 series boards. 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 FURY Renegade 7200 and below the FURY Renegade RGB at the time of writing.

What to Look for in an RAM for Core i9-13900K
Key buying criteria so you get the right fit the first time.
Intel chips take faster kits
13th and 14th Gen Core chips handle 6400MT/s and faster DDR5 more readily than AM5, especially on Z790 boards. Check the board's memory support list above 6400MT/s.
32GB is the gaming default
32GB covers games with browsers and chat running. 64GB suits video editing, large projects and heavy multitasking.
Watch heatspreader height
Tall or RGB heatspreaders can clash with large tower coolers. Low-profile kits avoid the problem.
Check for EXPO or XMP
EXPO profiles set speed and timings in one click on AMD boards; XMP does the same on Intel. Many kits carry both.
16GB is the floor, not the target
A 16GB two-stick kit runs most games but leaves little room for a browser and chat in the background. Plan to move to 32GB when budget allows.
Buy one two-stick kit
Two sticks run faster and more reliably than four on DDR5. Buy the capacity you need in one matched kit.

Frequently Asked Questions
Why does a new DDR5 system take long to boot the first time?
The board trains the memory on first boot, which can take a minute or more. Let it finish.
What happens if I don't enable EXPO or XMP?
The kit runs at a slower default speed. Enable the profile in the BIOS to get the rated speed.
Is 32GB enough for gaming?
Yes, for current games with apps in the background. Choose 64GB for creative work or heavy multitasking.
Is DDR5-8000 worth it?
On AM5, rarely; it often runs out of sync with the memory controller. It suits Intel builds tuned for high speeds.
Can I mix two kits?
It often fails to run at rated speed. Buy one kit with all the capacity you need.
Does RGB memory perform differently?
No. RGB adds lighting and height, not speed.
Bottom Line
Delta RGB 7200 CL34 suits boards that list 7200MT/s. FURY Renegade 6400 is the safer choice, and Delta RGB 64GB adds capacity.
