Greetings.
I would like to pair ASRock B650M-HDV/M.2 and AMD Ryzen 7 9700X.
And I have a few questions.
1. The current BIOS version for this motherboard, on the ASRock website of this motherboard, is 3.09. In the description of this BIOS it is written: Add "TDP to 105W" option for particular processors.
Does this also apply to the Ryzen 7 9700X?
2. In the supported RAM memory for this motherboard it says that it supports Kingston KF564C32BBEAK2-32. It's a Kit of two sticks 2x16GB. As I understand this ram is optimized for Ryzen 7000 series processors.
Will this RAM model be able to achieve 6400MHz with Ryzen 7 9700X?
3. The list of supported RAM memory does not include this model G.SKILL 32GB Trident Z5 Neo RGB DDR5 6400MHz CL32 KIT F5-6400J3239G16GX2-TZ5NR. This RAM model is compatible with Ryzen 7 9700X.
Would this model of RAM be compatible with this motherboard?

1. Yes. That new 105W TDP setting is actually for 9700X because its default is 65W and people were complaining about it leaving performance on the table.
2. 7000-series and 9000-series have the same IOD (IO Die), which contains the memory controller. So there shouldn't be any compatibility differences, barring firmware bugs.
3. Motherboard manufacturers don't bother testing every RAM kits on the market. RAM kit manufacturers can also swap components without changing product names, so these things are just a "suggestion," as far as I'm concerned.
I'm extremely particular about RAM reliability, so I never buy these non-JEDEC "gaming" memory. I only buy JEDEC spec (unbuffered) ECC memory, like this one:
https://www.crucial.com/memory/server-ddr5/MTC10C1084S1EC56BR" rel="nofollow - https://www.crucial.com/memory/server-ddr5/MTC10C1084S1EC56BR
Yes, it's only 5600MT/s and with horrible(?) CAS Latency of 46, but I don't care.
No, I'm not telling anyone to buy them. Almost everyone buys "gaming" memory. I know I'm the odd one out.

Thank you for your reply.
ECC memory makes a lot of sense if it's a Workstation. And where stability comes first, at the expense of performance.
But this will be a mixture of Workstation and Gaming computer.
The Blazing M.2 Support List for this motherboard states that the Samsung 990 PRO 1TB is supported.
Would the Samsung 990 PRO 2TB also be supported on this socket?
My current processor is an i5-4460 with an LCPower LC-CC-120 cooler. The manufacturer of this cooler says that TDP: 180W. At Idle, the processor temperature is around 33 degrees Celsius. In video games at 100% processor load, the temperature does not exceed 50 degrees Celsius.
What do you think, would this cooler be able to cool the Ryzen 7 9700X if the power consumption was increased to the maximum and the temperature was limited to 80 degrees Celsius?

NVMe has been around for so long, any brand-name (and most non-brand-name) NVMe drives are all fine these days. Again injecting my opinion, I stopped buying Samsung SSDs after 970PRO days, because they switched away from 2-bits per cell to 3-bits per cell for their "PRO" models, completely eliminating the differentiating factor.
Samsung continues to charge more money for their SSDs based on brand recognition from the past, as none of their products have anything particularly special these days.
My go-to SSD brand these days is SK Hynix (P31 and P41), as they're just as fast as equivalent Samsung models, if not faster, and are more power efficient. I also like Crucial, as you KNOW you're getting Micron NAND chips. Buying SK Hynix SSD also means you KNOW you're getting SK Hynix NAND chips. You can say the same about Samsung, as they'd be using their own Samsung NAND chips, but again, no reason to pay extra for them. The only other things I watch out for are 1) 3-bits per cell and 2) DRAM buffer. I don't buy DRAM-less SSDs, if I can avoid it.
As for your cooler, assuming you kept the AM5 compatible mounting parts, I don't see any reason why it wouldn't work for you, even at 105W TDP setting.

In the market where I am, SK Hynix does not exist.
The closest equivalent to the Samsung 990 PRO is the Crucial T500.
Samsung 990 PRO costs 142 euros, Crucial T500 costs 185 euros.
So the choice is obvious.
I will try the 9700X with the existing cooler. If the temperatures are too high, I will easily buy a bigger cooler.
Since both of the RAMs I mentioned in the first post are compatible with the 9700X, I will get the Kingston model. Because G.Skill is too high. It will interfere with the CPU cooler fan.

Regarding the compatibility of the cooler with the AM5 socket, I have all the factory parts of the cooler.
It is surprising that the cooler was purchased before the AM5 socket existed, and it is still compatible with the existing parts. Just downloaded the new User Manual from the manufacturer's website.

Indeed. Almost all AM4 coolers are compatible with AM5 because AMD kept all the dimensions the same. AMD is very good with that sort of stuff.
