9900X memory

Absolutely awful value to be honest.

You should be spending sub £200 for 2x32GB 6000mhz CL30 RAM with RGB.

Ok thanks, I know these are similarly priced but are these any better? Just want some good RAM that will run at decent speeds and should last the lifetime of the board if I swap CPU to a zen 6 in a few years.

The Gskill is a pretty top end bin at C28 6000mhz but the value proposition is very poor. You'll notice very little difference over something like this:

Zen 6 is likely to support much faster DDR5 than Zen 4 and Zen 5, so I'd be tempted to buy whet works well for Zen 5 now.

The other option would be to go for something like 7200mhz or higher that might suit Zen 6 in future but I'm not sure it's worth it with DDR5 moving towards CUDIMMS.

ok cool, sadly that corsair is out of stock.

I assume this is similar ?

will purchase again for Zen 6 as otherwise I pay a huge premium for 7200Mhz

What's your main use case? If gaming the 9900X wouldn't be my first pick.

its a mix of work and gaming, its replacing a 5900X and don't want to drop cores as its been brilliant for VMs and in all honestly I am not chasing 1% lows as I have never noticed issues with the 5900X.

Only upgrading as I want more m2 slots and I have the opportunity, plus my youngest needs a CPU upgrade

I assume you're aware of the issues with USB4 and lane sharing on X870? If your only reason for the upgrade is more M.2 slots, this may not be the optimal choice.

I wasn't aware however having looked this up I can't see it being an issue from my perspective. Only USB devices I will be using are standard peripherals and phones plugged in for debugging. I assume this only affects high transfer speeds on USB 4 devices ?
 
Tetras said:
The issue more generally is that Ryzen 7000/9000 CPUs have 8 PCI-E 5.0 lanes spare which can be used for M.2 slots.

On pretty much every X870/X870E board (where USB4 is now required by AMD), they take 4 of those 8 lanes to use for USB4.

That means that the board is left with only 4 lanes for a PCI-E 5.0 M.2 slot.

If the board wants more than one PCI-E 5.0 M.2 slot (or just more than one M.2 slot from the CPU), that is no longer possible without stealing lanes from the graphics card.

For example, for the X870-F Strix:
- If you use the 2nd M.2 slot, it takes 8 lanes from the graphics card.
- If you use the 3rd M.2 slot, it disables a PCI-E slot.

I think the Nova is currently all the rage with M.2 slot lovers, because ASRock didn't even bother to have a second PCI-E 5.0 M.2 slot. You get one from the CPU and the other 4x M.2 slots are from the chipset instead.

Ok in my case I would hope to fill at least 3 m2 slots maybe all 4. Most of which will be PCIE 4.0 speed. Does this cause me an issue ?

Sorry Tetra, trying to make some sense of this. from what i can read this only affects PCIE 5.0 Speeds ? So in my case I would still be fine with 1 x m2 5.0 and the rest at 4.0 or am I totally misunderstanding this ?

The lane sharing is hard wired, so it doesn't matter what gen your drives are, the GPU lanes will be taken anyway.

3 would be no problem with the X870-F Strix if you use slots 1, 3 and 4 (except it will disable a PCI-E slot). If you use all 4 slots, you will get 8 lanes less on the GPU. The performance impact of this is pretty small, but if someone is spending £1000+ on a GPU they're normally annoyed by it, even if the performance loss is only a few percent.

Thanks Tetra,Ok 3 NVME drives will be fine, a little annoying but not the end of the world. Which PCIE slot does it disable ? trying to work out of I can still use my sound blaster z as its incredibly handy having two sound cards.

There's a full length PCIE slot at the bottom of the board, that is disabled if you use M.2 slot 3.

typically that's where my soundblaster z is, however looks like I can move it up one to a x1 slot. Although can't see an unshrouded picture to see if its too close to the GPU

Edit looks like it doesnt even have one

Aye, I can't see one.

Perhaps this isn't the best pick for you.

If you have no intention of using USB4, you could get the X670E-F Strix?

Lol was wanting to steer clear of Asrock due to the 9800X3D issues however as I haven't purchased that chip and no doubt a bios fix will soon be released I am hopeful this won't affect me in the slightest and having 4 useable nvme slots is well worth it. Will only be jumping on X3D if Zen 6 releases with single 12 core CCD.

The Nova would have 5 usable plus a slot for your soundblaster, so far as I can see :o It does disable a PCIE slot, but shouldn't be an issue.

I'd suggest the X670E-F Strix as a suitable pick otherwise, if you want to avoid ASRock.

Yeah I had considered that however it looks as though usb 4 could be useful after all as I can drive a monitor with it which is useful in my three monitor setup as I have always had the vram staying high on AMD cards if driving more than one monitor. So correct me if I am wrong but I think usb 4 and the hdmi on the board means my two side monitors can be driven off the 9900x integrated GPU ?
 
Tetras said:
Yeah, the board says it supports DP through USB4, but as for how well this works in reality in regards to drivers 'n such, I have no idea.

Thanks for all your help on this. I would have ended up with a bit of a duff board had you not intervened.

Edit - looks like asrock have a bios beta for this already.
