Some of the Prime Asus boards don't have a TPM module for some reason. It's such a weird thing to cheap out on...

I assume that could cause issues for Windows 11 installs...

Holy **** balls lol. But as mentioned there are actually 3 types of TPM and windows 11 accepts any of them, the cheapest TPM is just software that sits on the mobo bios. A TPM chip soldered to the board or a removable TPM module is the most expensive and I can understand why cheap boards would not use it (a removable or physical TPM module is $50usd, that's a lot of money for a single component on a motherboard)

That's really interesting, thanks. Suppose it doesn't matter then, in that case.

Does that mean that in theory, even quite old motherboards can have TPM support added via a BIOS firmware update?

Not via update but there are TMP modules you can plug in to some motherboards not sure if its a proprietary port or not, your forever asking questions that could be answered with a quick google :confused:

CPU’s carry TPM now, it’s fTPM on AMD CPU’s.

No need for TPM module now, only use cases would be on holder hardware to support new TPM requirements or perhaps extending new hardware, if newer TPM versions are released.

Its a non issue really.

general rule is if it works, don't bother
but on a new platform like AM5, I would go for every update

Thanks mate, so forgive me for asking a stupid question.

I know my bios works fine, if I update it and it bricks my system do I just use the bios roll back button or do I need to re download the bios and setup a usb and do it that way?

Always update the bios via the inbuild tool in the bios with it on a usb stick.

Thanks mate, that was nice and easy, all updated now. Thank you.

I know it's not much but I was getting 37,500 on cinibench, since bios update and chip update I got to 37,850~ so a slight improvement.

Do Zen 3/Zen 4 CPUs have a separate cache (Ring) clock like Intel CPUs? Or, is the cache frequency tied to (determined by) the average core frequency?

Assuming it's tied to average clock rate, should be interesting to see how significantly higher cache frequencies on Zen 4, affect performance of Zen 4 vcache CPUs, relative to the 5800X3D.

Can any of you fine Zen 4 people comment on your experiences so far? Any good?

There's been quite a lot of negativity since the announcement of X670 motherboard prices (which were obviously going to be expensive). People don't seem happy to pay £150-£200 for a B650 motherboard either, despite this being what previous generation boards were priced at on launch.

I think many people on these forums have already got a DDR5 LGA1700 system too, so it would be a sidegrade for them, unless buying an expensive 7950X, which would only be a benefit for multithreaded software.

I bought a Ryzen 7700X (with a 10% discount) a couple of days ago, but I'm waiting for greater availability of B650 boards and hopefully a DDR5 RAM price cut before building the system.
