Keysight Reveals DDR5 Testing & Validation Systemby Anton Shilov on February 6, 2019 8:30 AM EST
Keysight, an electronic measurement company, has introduced the industry’s first off-the-shelf testing and validation system for DDR5 DRAM. The N6475A DDR5 Tx compliance test software is aimed at developers of various products that will use the next-generation memory.
Keysight’s DDR5 testing and validation system includes the company’s N6475A DDR5 Tx compliance test software as well as its own M8040A 64 Gbaud High-performance bit error rate tester (BERT) and Infiniium UXR-Series Real-Time Oscilloscope hardware (though it can work with other hardware too). The application performs jitter, electrical, timing, as well as eye measurements, and is designed to test the transmitter PHY of DDR5 SDRAM, data buffer, and register chips. The program automatically compares the results with the DDR5 spec test limits and shows how closely the device passes or fails each test.
Previously developers of various DDR5 products had to design their own testing software or perform all the measurements and analysis manually, which greatly lengthens development time. Now that Keysight’s DDR5 Tx compliance test software and hardware is available, it will be far easier for engineers to optimize transmitter, receiver, and channel designs. So this should speed up how quickly hardware vendors are able to bring DDR5-based devices to the market..
Keysight’s N6475A DDR5 Tx compliance test software and appropriate hardware is now available. Pricing is available upon request.

VivaLaPanda - Wednesday, February 6, 2019 - linkI remember hearing about one of our engineers getting Doom to run on one, but I don't know about Crysis...
willis936 - Wednesday, February 6, 2019 - linkIt’s really bizarre to see T&M news coverage on a tech site. Judging from the comments it doesn’t feel like it belongs here. Were you guys at designcon?
Mr Perfect - Wednesday, February 6, 2019 - linkIt's not unwelcome though. Knowing the state of DDR5 testing gives us a teaser on how development is going. I suppose 2020 is to much to hope for though.
rocky12345 - Wednesday, February 6, 2019 - linkHey we will never need more than 640K oh wait that's not right. Yes for sure good to see DDR5 may move forward and at some point actually come to the market. The only thing that sucks is I am planning on upgrading to one of those shiny new Ryzens in June-July time frame and they only support DDR4. So if I upgrade now then a year later DDR5 releases I will feel like I do now with my DDR3@2400MHz slow and using outdated tech....:) But hey I guess if I get fast enough DDR4 it won't matter to much anyway.
HollyDOL - Wednesday, February 6, 2019 - linkIt will probably take another year before you can get modules decisively faster while running at reasonable voltage. Getting new Ryzen in 4-5 months with DDR4s should not disappoint you at all.
rocky12345 - Wednesday, February 6, 2019 - linkI was thinking the same thing after I posted my comment. I am still going to pick up the new CPU & Memory & main board and enjoy my new toys.

It's not as if I expect any AnandTech readers to buy the system (though we do have a lot of industry readers, funny enough). However it's a useful proxy for keeping an eye on DDR5 development, especially as there aren't going to be any "big" announcements this soon.
DanNeely - Wednesday, February 6, 2019 - linkWe've seen a handful of other posts about the first DDR5 dram chips and first stand alone DDR5 memory controllers over the last year or two. I don't see anything out of line from that in also reporting the first test machine.
willis936 - Wednesday, February 6, 2019 - linkIt’s a suite of machines and they test a lot more than just DDR5. Keysight is also not first to market for DDR5 test solutions. I’m sure there’s is very good and is priced appropriately. There is always news in this space but it isn’t covered by a site like anandtech because the readers are consumers more than they are engineers. Where are the anandtech articles covering 400GBASE-KR4 development?
VivaLaPanda - Wednesday, February 6, 2019 - linkYeah, I think this is the first time I've seen our products in wider ranging tech news
