Nvme 4.0 in 5.0 slot?

[KrzysiuM]

Will installing NVME 4. 0 in a 5. 0 slot slow pci express x16 to x8? I have an MSI X670E Tomahawk motherboard. I have an NVME drive installed like this, and will it affect the speed of the graphics card connector?

While true built paying PCIE 5.0 prices and not using the full drive spec would be rather dumb. Waste on money.

Now having a PCIE 5.0 supporting Motherboard is a good idea, because with that you can at the very least run 2x PCIE 4.0 NVME SSDs at their full speeds., again... minimum.

Why buy a PCIE 5.0 SSD at all since you can only use one of them at those speeds.

prices are not that much in all cases.

in fact if you look today for the few pcie3 ones still being sold.. many pcie4 ones are cheaper at same volume.
if you want an card for that old motherboard just get that pcie4 one who cares it just works at max speed.

and for some models of 5x vs 4x depending on where you live the same is true.
and also there are very few PCIe 4.0 x 4 m.2 that run at that 12000mb/s those that run near that might be more expensive than those that run over that speed PCIe 5.0

so in some cases it might be cheaper (or you end up with more actual usuanle speed) to go PCIe 5.0 even if you only got a 4.0 slot.

I bought a Gen 4 because they were cheaper than Gen 2 and 3. So I look at it this way, I can always use it on future builds with proper max speeds. Gen 4 in a Gen 3x4 is not as bad as you may think. The speeds are Gen 3x4.

I believe its running at under 800MT/s of the Gen 4 but I have no time to check.

Where the F did I say anything about buying or using PCIE 3.0 SSDs?
Right... no where. So why are you bringing it up like you're correcting me on something.

PCIE 4.0 are the normal everyday SSDs.
PCIE 5.0 are for rich people who are so dumb they can't manage their money that they waste it on stuff you can't possibly see those speeds in anything you do. Now if you use your PC for a job that's always pulling in money, maybe. Like an actual Pro User who's using that PC for some serious Video Editing work and such, again maybe. Otherwise, no... pointless to buy any PCIE 5.0 stuff for a Gaming PC.

Crashed lähetti viestin:

From what it looks like, assuming you install a Ryzen 7000 series processor, there are 24 usable lanes of PCIe 5.0, so a motherboard may be able to provide both full bandwidth GPU and NVMe. Definitely check your motherboard specs however.

I'm so tired of going over this.

CPU is for GPU Lanes
Chipset is for everything else.

This is incorrect. Go look at the block diagrams or motherboard manuals. Crashed is correct.

AMD Ryzen 7000 Series Desktop Processors

M.2_1 slot (Key M), type 2242/2260/2280
(supports PCIe 5.0 x4 mode)

M.2_2 slot (Key M), type 2242/2260/2280/22110
(supports PCIe 4.0 x4 mode)

AMD X670 Chipset

M.2_3 slot (Key M), type 2242/2260/2280
(supports PCIe 4.0 x4 mode)

Ryzen 7000 desktop CPUs have enough PCIe lanes for 24 lanes from the CPU; such as the above board with 16x lanes going to the top PCIe x16_1 slot, 4x lanes going to the top M.2_1 socket, and 4x lanes at PCIe Gen4 going to the second M.2_2 socket.

There are no PCIe Gen4 x4 SSDs that will do anything close to 1200MB/s. PCIe Gen4 has a theoretical maximum of 2GB/s per-lane for a total of 8GB/s (8000MB/s) on an Gen4 x4 connection. Most are going to hit the limits of the bus at about 7800MB/s.

The only M.2 SSDs that are going to get anywhere close to 1200MB/s are PCIe Gen5 x4 disks.

Pretty sure you are confusing MB/s and Mbps

I think he just chopped off the 3rd 0 for 12,000 (12000) which makes his post look like he thinks 1200MBps is more than 7800MBps. I don't think it's a MB/Mb issue since disk speeds typically aren't measured in bits per second. I think it's a 1200/12000 typo.

[Bad 💀 Motha]

PCIE 4.0 x4 has a bandwidth of 8GB/s
There are plenty of NVME SSDs with that spec able to hit 5000MB/s

Again when you view most SSDs you will see this but that's just the Read Speed and doesn't speak for full specs of the drive or real world usage benefits. As again IOPS is much more important then R/W speeds alone if the drive is being used for heavy tasks or as an OS drive.

^this.

Just missed the third 0 in 12000MB/s e.g. 12GB/s. Seems pretty obvious considering what I was replying to.

I am awake now so let's take a peek at this motherboard manual:

Please be advised - If your M.2 SSD equips its own heatsink, please remove the M.2 plates or rubber cubes in the M.2 slots before installing M.2 SSD. Do not re-install the heatsinks supplied with your motherboard.

M2_1 [From CPU]

M2_2, M2_3, M2_4 slot (From X670 chipset)

PCI_E4 & M2_4 share the bandwidth. M2_4 will run at x2 speed when installing a device in the PCI_E4 slot.

So it will share the bandwidth with the 4th GPU in the 4th PCIe slot.

That’s how rumours are made. It’s kind of true but who does actually use all 4 PCIe slots for GPUs? Miners? AI devs?

Also interesting how people spend extra on a x670 board and never use extra PCIe lanes they pay for.

WTF you mean 4th GPU?

It's saying the 4th M2 Slot is shared with the 4th PCI/PCIE slot but that's only if you populate that slot with something that needs that bandwidth such as an HD Capture Card or WiFi/LAN card for example
