Speed and timings

7 of 8 differ

Rated speediData rate of the kit's fastest XMP or EXPO profile, the speed on the label. A kit without a profile shows its JEDEC speed. A speed the maker writes in MHz, such as 6000MHz, is the data rate, so it is 6000 MT/s.

Kits with two profiles at the same speed list the second set in the variant source note. The QVL tab of the product page differs from the sheet for some SKUs. The sheet is stored. QVL gives 36-46-46-110 at 1.35V where the sheet gives 36-36-36-68 (PVV516G56C36, PVV532G560C36K, PVV532G56C36) or 36-36-36-76 (PVV516G600C36GK, PVV532G600C36K, PVV548G600C36K, PVV564G600C36K, PVV58G600C36G), and for PVV564G560C40K the sheet gives 40-40-40-76. QVL gives 36-36-36-68 at 1.25V for PVV564G520C40K where the sheet and the page table give CL40 at 1.35V. QVL gives 1.25V for PVV516G520C36K, PVV516G52C36 and PVV532G52C36 where the sheet and the page table give 1.2V. QVL gives 32-40-40-84 for PVV564G640C32K where the sheet gives 32-42-42-84.

Overclocking profilesiProfiles stored on the modules. EXPO ULL is AMD's EXPO Ultra Low Latency profile. None means the kit has no XMP or EXPO profile and runs from its default SPD settings. This includes a faster default speed with no profile, such as Kingston Plug N Play. Every DDR5 kit listed as Intel XMP is XMP 3.0. Every DDR4 kit listed as Intel XMP is XMP 2.0. The order follows the maker's list, profile 1 first.

Intel XMP 3.0, None (no XMP or EXPO)2Maker spec sheet (PDF)kingston.com/datasheets/KF556S40IBK2-32.pdfRead 15 October 2026Datasheets of the 4800, 6000 and 6400 MT/s kits list XMP profiles and say the module supports Intel XMP 3.0. The 5600 MT/s datasheets list only a Plug N Play default and no XMP profile, so they are stored as None. Kingston retail listings and the press release say Intel XMP 3.0 certified for the line, which conflicts with the 5600 MT/s datasheets.

Intel XMP 3.0, AMD EXPO1Maker product pagepatriotmemory.com/products/viper-venom-ddr5-performance-ramRead 14 October 2026The Feature Overclock line of each SKU sheet is stored: XMP 3.0 only, or XMP 3.0 and EXPO. 13 sheets state XMP 3.0 only in that line but also list EXPO profile rows in their tested profile list (PVV516G52C36, PVV516G56C36, PVV516G60C30, PVV532G52C36, PVV532G56C36, PVV532G560C36K, PVV532G60C30, PVV532G600C36K, PVV532G620C40K, PVV564G520C40K, PVV564G560C40K, PVV564G600C36K, PVV58G600C40).

It matches the sheet for that SKU.

Default speed (JEDEC)iSpeed the kit runs at without a profile. Makers call it SPD speed or default speed. The data rate in MT/s. A maker's SPD speed written in MHz, such as 5600MHz, is 5600 MT/s. A tool such as CPU-Z shows half the data rate, so DDR5-2400 in CPU-Z is 4800 MT/s.

Module heightiHeight of one module from the bottom edge of the contacts to the top, with the heat spreader and light bar as sold. It decides the clearance under large CPU air coolers. This is the vertical height standing in the slot, not the board thickness. Makers write L x W x H, and some call the standing height W. Use the middle number of the three. A size with only two numbers gives length and height, so the smaller is the height. The longest is the module length and the smallest the thickness.

AIDA64 memory test (measured)iAIDA64 Cache and Memory Benchmark results from a reviewer, one row per tested kit and setting. Read, write and copy are in MB/s as AIDA64 prints them, where 1 MB is 1,048,576 bytes. Results depend on the CPU and board, so compare rows from the same CPU only. AIDA64 switches a result of 100 GB/s or more to GB/s, where 1 GB is 1024 MB, so 113.64 GB/s is stored as 116367 MB/s, rounded to a whole MB/s. The printed figure goes in the source note.

The values are printed on the review bar charts of read, write, copy in MB/s and latency in ns. The JEDEC rows are the kit run at 4800 MT/s CL40 and 5200 MT/s CL42, with timings beyond CL not printed. The 5600 MT/s row is the SPD Plug N Play profile CL40-40-40 at 1.10V. The 6000 MT/s row is the overclock described below, 36-38-38-67 at 1.10V as the AIDA64 and CPU-Z screenshot shows.
