SK hynix has unveiled the fastest DDR5 MCR DIMM server memory - it is 80% faster than standard modules

SK hynix has announced the fastest DDR5 server memory modules - it has 8000 MT/s (or 8 Gbit/s).
This is about 80% faster than the standard DDR5-4800 modules used in the server segment.
The key feature of SK hynix DDR5-8000 server memory is Multiplexer Combined Ranks (MCR) technology, developed in collaboration with Intel and Renesas.
By using a special chip developed by Renesas that acts as a data buffer, SK hynix has made it possible to simultaneously use two memory ranks (chips on both sides of the module) to increase the data channel width to 128 bits instead of the usual 64 bits.
The Renesas chip acts as an intermediate between the CPU and the RAM module, as shown in the diagram below.
The new memory architecture provides the ability to simultaneously route twice as much information to the CPU as conventional DRAM modules.
As a result, achieved a significant increase in the speed of the modules without the need to increase the frequency of the memory chips themselves.According to the vice president and general manager of memory interface development division in Renesas, Sameer Kuppahalli (Sameer Kuppahalli), the development of the data buffer took three years of intensive work.
Intel, on the other hand, says it is looking forward to the application of MCR technology by future Xeon platforms.
SK hynix expects that the new memory will be in demand in the HPC-segment, but it has not yet announced the date of mass production of MCR DIMM memory.

AMD: optimal memory for Ryzen 7000 is DDR5-6000

AMD Technical Marketing Director Robert Hallock in the company's official Discord channel said which memory configuration would be the most optimal for the Ryzen 7000 series processors.
From his point of view it is DDR5-6000, but there are nuances.Image source: AMDThe technician said that the best choice of DDR5 memory for enthusiasts will be modules with a speed of 6000 MT/s (million transfers per second).
By \"best choice,\" Hallock means the option that offers the best cost, stability, performance, availability and ease of use.
In addition, he recommended that users use two RAM modules because four, while supported, would make signal routing difficult, compromising maximum performance.AMD previously confirmed that the Ryzen 7000 processor series officially supports DDR5-5200 memory for peer and dual-peer configurations with one DIMM module per channel.
With two DIMM modules per channel, the officially supported speed drops to 3600 MT/s:According to earlier rumors, X670 motherboards formally support a maximum FCLK (Infinity Fabric frequency) of up to 3000 MHz.
However, the default configuration is 1733 MHz.
Given Hallock's statement, users are allowed to leave FCLK in the AUTO position.
For the Ryzen 7000 series, the 1:1:1 frequency ratio for FCLK, UCLK and MCLK is not as important as before.
The main thing to pay attention to is the memory to controller frequency ratio - it is better if it is 1:1.
Successful Ryzen samples can overclock up to 2000 MHz in FCLK, but such configurations are not a priority for AMD.
In the originally supported DDR5-5200 mode, all three clocks will run at a 2:1:1 ratio and 1730:2600:2600 MHz.

AMD X670 (Extreme) chipset motherboards will start selling the same day.

AMD introduced EXPO technology for easy overclocking of RAM on Socket AM5 platform

During the nightly presentation of Ryzen 7000 processors and new Socket AM5 platform, AMD also officially introduced new technology that is designed to make overclocking of DDR5 RAM much easier.
It is named AMD Extended Profiles for Overclocking or AMD EXPO for short.Image source: AMDEXPO is an alternative to Intel XMP 3.0 technology.
It is specifically designed for Socket AM5 platform and Ryzen 7000 processors, and allows the user to easily select the desired speed of RAM operation within RAM profiles, announced by the manufacturer.
According to AMD company, using EXPO technology allows to easily increase the gaming system performance at 1080p resolution by up to 11%, and reduce the memory lag to around 63 ns.
AMD said it aims to distribute EXPO under a free and royalty-free license, which will accelerate its adoption by memory manufacturers.
The company said that many manufacturers have already adopted AMD EXPO and are about to release more than 15 bundles of EXPO memory modules with effective frequencies up to 6,400 MHz.
These companies include ADATA, Corsair, GeiL, G.Skill, Kingston and others, for example.
The first DDR5 RAM modules with support for overclocking profiles have already been introduced.
For example, such solutions were announced by GeIL, Corsair and G.Skill.

DDR5 modules in the last six months noticeably fell in price in the global market

Prices of DDR5 standard RAM modules are still significantly higher than DDR4 memory, but over the past six months have fallen to more or less acceptable values.
That's according to Tom's Hardware, which analyzed offers from major U.S.
computer stores like Newegg and Amazon.Image source: ComputerBase.deIt makes sense that low-speed DDR5 modules with high timings are more affordable.
In this case the price for 1 GB of memory will be around $6-7 or $120-130 for a set of two modules with a total of 16 GB.
This is considerably less than the price, which sellers were asking for memory of the new standard at the start of its sales.
Sets cheaper than $ 500-1000 at that time to find in the free sale in principle not possible.
Fortunately, the manufacturers of DDR5 memory chips optimize their production, the lack of components weakened, and it is only natural that the modules of the new memory standard began to get cheaper.
At the same time, Tom's Hardware notes that the decline in prices is observed not only in the U.S., but also in Europe.
The data confirms the German portal ComputerBase, which reports that the average price per gigabyte of DDR5 memory on the European market has dropped to nearly €5.
In the U.S., the most affordable sets of DDR5 memory with a total capacity of 16 GB offered by brands Crucial, Kingston and Patriot.
Variants with a frequency of 4800 MHz and CL40 timings can be purchased for $110-120.
Faster kits with 5200-5600 MHz and CL40-CL36 timings are available for $120-180.
Sets of two DDR5 RAM cards of 16 GB each (32 GB total) at 5200 to 5600 MHz and CL34-CL36 timings can be found for less than $250.Image source: Tom's HardwareFor even higher speed modules with 6000 MHz and CL32-CL36 timings you would have to pay over $300.
This is still very expensive, but much cheaper than a few months ago.
For example, back in December last year, a 32GB set of G.Skill Trident Z DDR5-6000 CL36 RAM was offered for $4000 (four thousand dollars).
In January, its price dropped to $800.
And today the exact same memory and even with lower latencies can be found \"only\" for $380.It is very likely that by the release of Ryzen 7000 processors, which will work exclusively with DDR5, memory modules will fall even further in price.
