CPU Upgrade TG02-0000a / ERICA8 / N00595-606

[MaxProAndU]

We know that the Erica8 AMD Cezanne PROM WIN motherboard will support the six Zen 3 Cezanne 5000 series APUs, but has the BIOS been updated to support Vermeer 5000 series CPUs?

There may be a slight understanding of why the 5800X/5800X3D and 5900X/5950X 105W CPUs might be in question, but the additional 40 watts drawn should have less to do with motherboard. Possibly more with the inadequacies of the fan assembly.

So will the board support additional Zen 3 CPUs beyond Cezanne?

Thankx

@MaxProAndU,

Unfortunately, it appears that the answer at this point in time is no: your Victus by HP 15L Gaming Desktop TG02-0137c PC (575S2AA), according to: https://support.hp.com/us-en/document/c08368395, as fitted with an Erica8 motherboard with SSID: 89D8, and the fastest processor I have seen online by any (super) User is still an AMD Ryzen 7 5700G.

Example of the sources I looked at: https://www.userbenchmark.com/System/HP-Victus-by-HP-15L-Gaming-Desktop-TG02-0xxx/263041, (scroll through the Intel & AMD HP Victus by HP 15L Gaming Desktop TG02-0xxx models mixed together).

Kind Regards,

Indeed.

That was what we were findings, and had become our conclusion too.

One of our team members is a firmware debugger, and has been working with BIOS/UEFI firmware for nearly 30 years. He decided to take a crack at the AMI source code within this motherboards SSID series for a B550A.

Earlier versions of the BIOS indicate that the firmware establisher is Pegatron (possible board manufacturer for the Erica series?), but was later removed. Possibly an error on American Megatrends' part.

The Cezanne support is "hacked" into place, more like a white list, over neutralized CPUs that are partially "still in place"as listed AGESA Combo-AM4 V2 1.1.0.0. This may have been a simple checksum remedy, to keep from recording the firmware as a complete build.

Even on the latest version of the firmware, AMD's Combo-AM4 v2 AGESA microcode is very old: "1.2.0.2". This has been possibly done to avoid the newer Platform Initialization v2 AGESA, as it would force the acceptance of CPUs beyond the Cezanne APUs, and require extensive debugging to keep the white list in place. This does leave the board and somewhat of a poor chipset security risk. The current update AMD AM4 AGESA Combo V2 PI was released last week: 1.2.0.8

And all the changes that are in the BIOS upgrades, are more about supporting OS changes. Even the iGPU for each processor is not optimized, ironically trading them as a Radeon RX Vega 6, regardless of the calculate units.

After some discussion, the nine of us, especially Mr. TT here, feel that it's a sad waste. Given AMDs recent Platform Initialization firmware tools for AMD64 architecture, given six people with coding experience and about an hour implementation of the AMD Generic Encapsulated Software Architecture could be used to build a clean firmware installation for the BIOS. And it would still have all of HP's bells and whistles.

It's really too bad. Our client ask us to look into this, so we'll let them know to cancel there $360,000 pending order submission in the morning. They had asked HP business sales direct, but only got the response " It's not in the CTO"
