HP AMD Ryzen Pro PSB Status Tested Via an HP EliteDesk 805 G6 Mini

Just like a quick update. We know a lot of people were excited about the Lenovo Vendor Locking Ryzen based systems with AMD PSB that we made. After completing this piece, we now have several systems in place to validate this on other platforms that we are testing. While we were working on the Lenovo ThinkCentre M75q Tiny Gen2 35W AMD Ryzen 5000 part where we found the PSB vendor lock, we also started working on an HP EliteDesk 805 G6 Mini. This is where we were able to test using our new setup.

Testing an HP EliteDesk 805 G6 AMD Ryzen Pro PSB State

For a quick overview, Lenovo locks down AMD Ryzen Pro processors using a feature called AMD PSB, or Platform Secure Boot. Although we’ve seen Dell EMC and Lenovo use it in the AMD EPYC line, and Lenovo use it in the EPYC-derived Threadripper Pro line before, this was the first time we’ve seen it in desktop PCs. company 1L. Specifically, we found it on the Lenovo ThinkCentre M75q Tiny Gen2.

The question posed at that time was “Which other vendors use PSB?” Dell, for its part, doesn’t really have many AMD Ryzen Pro series OptiPlex systems. It’s a shame because the Ryzen 4000 and Ryzen 5000 series systems are very good, especially in the 35W TDP 1L form factor.

HP has been a struggle. We have two HP EliteDesk 805 G8 Mini systems on order and have been ordering them for over a month. While HP’s website for the same configurations only lists a few weeks for delivery, our units now have a March ETA. Let’s be clear, what HP is doing is despicable. HP billed us in early January. He knows he can’t produce the boxes within the timeframe suggested on the order page because our exact same configurations have earlier ETAs on the HP online ordering portal. This is a despicable business practice on the part of HP, as it knows its estimated ship dates are not real, but uses dates it knows to be false to collect funds from customers. Nevertheless, here we will consider the technical merits of HP and AMD PSB.

Although ordering through HP is a challenge, we were able to get an EliteDesk 800 G6 Mini through eBay and an STH Jose YouTube player. We’ll have the full review of this unit in the not too distant future (it’s in Alex’s edit queue.)

As this is an important industry topic, we wanted to test whether this HP EliteDesk AMD Ryzen Pro 4000 series also uses AMD PSB vendor lock like Lenovo’s competing line.

For this effort, we used three motherboards from the enthusiast space. You’ll see small preview thumbnails of them on STH in the coming weeks as Eric has already completed the short pieces about them. The first was an ASUS ROG STRIX B550-I Gaming mITX platform in a compact InWin B1 chassis.

We also used the ASUS TUF GAMING B550M-Plus WiFi as a non-mITX control. We probably could have done without it, but it came before the mITX ASUS platform and came with the AMD Ryzen 7 5700G which we used as our check processor to make sure it worked in ASUS’ systems. and Gigabyte.

To make sure we weren’t only validating with ASUS and the B550 chipset, we also got a Gigabyte X570 I Aorus Pro Wi-Fi unit.

With that, we had three motherboards, two chipsets, and two vendors to test with, along with a Ryzen processor that also had integrated graphics.

HP EliteDesk 800 G6 Mini-CPU Review

It’s a bit repetitive to show what happened, but on all three platforms we saw the systems boot up with the AMD Ryzen 7 Pro 4750GE from the EliteDesk 800 G6 Mini:

Everything worked as we would have expected. Something we didn’t see in firmware for Gigabyte or ASUS was a PSB feature.

In short, ASUS fared better than Gigabyte with TinyPilot Voyager compatibility.

Last words

Based on our single-unit sample, it doesn’t look like HP is locking down its AMD Ryzen Pro processors. Dell, for its part, does not have a competing product (but uses PSB on its EPYC servers). This only leaves Lenovo to use AMD PSB for CPU vendor lock-in. As we mentioned earlier, it is up to the OEM of the system to decide if they want to enable AMD PSB at the factory. The reason for this is to ensure that there is no tampering between the factory and the customer.

Now for the bad news, if you’re trying to get an HP EliteDesk 800 G6/G8 Mini from HP, the HP online store is misleading consumers with estimated ship dates. We have orders for two different configurations, we have contacted the HP PCE team and HP is quoting dates on their website that they know they won’t.

The positive side is therefore that HP does not lock the processors of the G6 generation. The downside is that it’s difficult, if not impossible, to get the HP EliteDesk 805 G8 Mini right now from HP. As soon as we receive one, we now have the test device in place to see if HP uses the PSB in this generation. If not, we’ll just turn to the secondary market and source one.
