However, the SK hynix M-die ICs were easy to overclock, and we got the memory kit to DDR5-6600 with the exact advertised timings (32-39-39-102) for DDR5-6400.

Although this data is based on our easier to execute bot match, the 128 player modes don't see any improvement with the higher bandwidth DDR5 memory either. With this many factors in play, we really didn’t know what to expect when we tossed several modules into our test systems for a modern-DDR throwdown. All product specifications reflect internal test results and are subject to variations by user’s system configuration. A new level of speed, improved capacity, and bolstered reliability are packed into DDR5 to enhance overall system performance. Skill's recent Trident Z5 RGB DDR5-6400 C32 memory kit is a testimony that DDR5 is progressing in the right direction.So for now DDR5 will thrive in applications and games that require big memory bandwidth and aren't as sensitive to latency. The DDR4 memory was tested on the MSI Z690 Tomahawk Wi-Fi DDR4 and the DDR5 memory on the MSI Z690 Unify. Pricing aside, DDR5 has little to offer over DDR4 in today's games with an Alder Lake processor for the most part. Since the JEDEC DDR4-3200 standard is a BIOS option for the DDR4-supporting Z690 Extreme WiFi 6E, we selected it to form our performance baseline in the tests that follow.
G.Skill Trident Z5 RGB 2x16 GB DDR5-6400 CL32 Review
When it comes to DDR4 memory, we see again that the sweet spot is around the 3600 mark, with DDR4-4000 barely reducing latency from what was seen with the CL16 3600 kit. In gear 1 mode, the memory controller operates at the same frequency as the DRAM, while gear 2 sees the memory controller operate at half the memory speed and this greatly increases latency, but can allow you to run memory at higher frequencies for increased bandwidth. But judging by the CL22 value, the DDR4 memory module most likely conforms to JEDEC's DDR4-3200 speed bin. Built-in voltage regulation plus iCUE software control makes for easier, finely-tuned output that provides more stable overclocking than ever. We revisited overclocking with the Team Delta kit and the Asus ROG Maximus Z690 Apex armed with a new BIOS and more adventurous voltage settings.
Each 64-bit rank of DDR5 memory (a rank being a subset of memory chips on a memory module) is divided into two 32-bit ranks, with the latency benefits described in that same overview article being applied in a slightly different way. With DDR4 CAS latencies below 20 in high-performing DDR4 memory, that "CAS 40" might sound concerning. It’s one of the reasons that a good set of Samsung-based DDR4-3600 with tight timings is still a perfectly viable gaming option. The astonishing performance raises the ceiling on big data processing, while seamlessly handling 8K content. It should also be noted that for the vast majority of games you can still easily get away with 16GB of RAM.
JEDEC finalizes DDR5 standard: Terabyte-sized DDR5-6400
But DDR5 supply is expected to improve next year, and so will pricing, so we wanted to take a more in-depth look at what DDR5 has to offer gamers when using an Alder Lake CPU, and this will help us determine at which point you should bother with the new memory technology.
DDR4-2933 offers a bit performance boost as it increased bandwidth by almost 30%, while DDR4-3200 using slightly weaker timings only improves bandwidth by a further 2%. For some reason Samsung isn't as widely supported, though with each new motherboard BIOS it is catching up.
Great Deal
