I have become annoyed by a few things which I only just learnt about last night.
An E-Mail seeking full clarification from AMD follows, follow the links yourself to check out what I am talking about.
Okay, when I brought my CPU and motherboard it was on the basis that I could run DDR5 memory at 6000Mhz all day long 24/7/365 but now I am being hounded with doubts which AMD is the cause of. You advertise EXPO as a feature of your systems allowing memory to run at 6000Mhz and in some cases beyond but then I get told about this on your webpage found here:
https://www.amd.com/en/technologies/expo hidden away in the bottom left hand corner where it is TOTALLY obvious under footnotes with a triangle beside it.
"Overclocking and/or undervolting AMD processors and memory, including without limitation, altering clock frequencies / multipliers or memory timing / voltage, to operate outside of AMD’s published specifications will void any applicable AMD product warranty, even when enabled via AMD hardware and/or software. This may also void warranties offered by the system manufacturer or retailer. Users assume all risks and liabilities that may arise out of overclocking and/or undervolting AMD processors, including, without limitation, failure of or damage to hardware, reduced system performance and/or data loss, corruption or vulnerability. GD-106"
Being that EXPO is a feature that is helping you sell boards - I want to know EXACTLY what you mean by the statement "outside of AMD’s published specifications" and I would like you to EXPLICITLY state what those Published Specifications are... if they are what is mentioned on your website under:
https://www.amd.com/en/products/apu/amd-ryzen-9-7950x3d which states you don't support memory running above the 5200Mhz Jedec standard then I feel it only fair to point out in the bottom of this page under yet ANOTHER hidden footnotes triangle the following:
"Game testing as of 5 December, 2022, by AMD Performance Labs using the following hardware: AMD Socket AM5 Reference Motherboard with AMD Ryzen™ 9 7950X, Ryzen™ 9 7950X3D and G.Skill DDR5-6000C30 (F5-6000J3038F16GX2-TZ5N) with AMD EXPO™; ALL SYSTEMS configured with NXZT Kraken X63, open air test bench, GeForce 4090, Windows® 11, PCIe® Resizable Base Address Register (“ReBAR”) ON, Virtualization-Based Security (VBS) OFF. All games tested at 1920x1080 with HIGH in-game preset and the chronologically newest graphics industry API available within the game’s rendering engine (e.g. Vulkan® over OpenGL™, DirectX® 12 over DirectX® 11). Desktop configurations will vary, yielding different results. Games tested: CS:GO, League of Legends, Assassin's Creed: Valhalla, Grand Theft Auto V, Hitman 3 Dubai GPU, Wolfenstein Youngblood (LabX), Hitman 3 Dubai CPU, Cyberpunk 2077, Borderlands 3, DOTA 2, Middle Earth: Shadow of War, F1 2021, Far Cry 6, Final Fantasy XIV, Warhammer: Dawn of War III, Shadow of the Tomb Raider, Total War: Three Kingdoms Battle, Deus Ex: Mankind Divided, Watchdogs: Legion, Riftbreaker CPU, Red Dead Redemption 2. RPL-035"
Now this shows that you are running EXPO enabled memory and are showing it as a feature so one can naturally assume that having EXPO set is not running out of "published specifications" one could also assume that taking a 7000Mhz XMP kit and running it at 6000Mhz with settings <= that of the EXPO kit would also not be outside "published specifications" unless of course you are meaning again the specification of 5200Mhz as stated on the previous URL.. in which case I feel AMD are being disingenuous and quite misleading.
You are hiding details that go against what you publicly advertise as features while excluding warranty on CPUs if you use said features. I see this as contradictory and a MASSIVE problem..
Do I want you locking things down?. No. No I do not.
Do I want you to be absolutely explicit in what you are saying? HELL YES. you need to be specific to avoid miscommunication. If you are saying that overclocking using EXPO past what you specify on your webpage for the 7950X3D will invalidate warranty then don't be wishy washy about it - damn well explain all the limitations explicitly or - you can expect users to come back at you and say - you didn't clearly and explicitly specify therefore contributory negligence.
Now please clarify your position on "AMD’s published specifications" be explicit and verbose and leave no room for any doubt.
