AMD preps for Ryzen 5's launch with a helpful AM4 motherboard update

Getting ready for Ryzen 5.

While AMD’s enticing Ryzen 7 processors battle Intel’s Extreme Edition chips for a fraction of the price, the AM4 motherboard platform is still in its infancy, as early adopters can attest. But Ryzen motherboards are becoming more polished by the day, and AMD just detailed a significant update ahead of the April 11 launch of the Ryzen 5 series of CPUs.

Ryzen motherboard BIOSes rely on the AMD Generic Encapsulated Software Architecture, and AMD’s Rob Hallock says that AMD’s pushing an AGESA update to its motherboard partners soon. Its tweaks are expected to appear in AM4 motherboard BIOS updates in early April.

Here’s what you’ll find in the update, verbatim from Hallock’s post:

  • “We have reduced DRAM latency by approximately 6ns. This can result in higher performance for latency-sensitive applications.
  • We resolved a condition where an unusual FMA3 code sequence could cause a system hang.
  • We resolved the “overclock sleep bug” where an incorrect CPU frequency could be reported after resuming from S3 sleep.
  • AMD Ryzen Master no longer requires the High-Precision Event Timer (HPET).”

That last bullet point is especially notable for gamers looking to squeeze more performance out of their Ryzen PCs. Overclocking your system and disabling HPET are two key tricks to maximizing Ryzen PC performance, so having AMD’s own Ryzen Master overclocking software dependent on HPET was a bit of a bummer. No more!

The April AGESA update is just another step in the path for Ryzen, not a final destination. AMD’s also planning an update for the first week of April that will improve how Ryzen behaves with Windows 10’s Balanced power plan, hopefully negating the need to set your system to the more power-hungry High Performance plan to squeeze the most out of your games. Another future update targets how finicky AM4 motherboards are with high-speed RAM, as Hallock explained in March:

“We intend to issue updates to motherboard partners in May that will enable them, on whatever products they choose, to support speeds higher than the current DDR4-3200 limit without refclk [reference clock] adjustments.”

But Ryzen performance boosts aren’t coming from BIOS tweaks alone. AMD’s working with developers to optimize performance in PC games. This very morning, Ashes of the Singularity released a beta patch that increases Ryzen performance by roughly a third in PCWorld’s testing. Hot damn. The company’s also inked a multi-game deal with Bethesda—the studio behind Doom, Fallout, Elder Scrolls, Prey, and more—to optimize performance on AMD hardware.

The impact on you at home: Improved performance and ease-of-use for Ryzen systems, which is a huge impact indeed. New computing platforms always have teething issues that disappear over time as the kinks get worked out, which is why it’s important in this specific scenario to ignore the common wisdom of ignoring most BIOS updates. You want those quality of life upgrades. PCWorld’s guide to updating your PC’s BIOS can help walk you through the process.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
