Hi Guys & Gals, Bought one of these thinking I could expand my storage with M.2 drives but I am having trouble getting it to run @ x16 it apparently can't see all drives if it is only running at PCIe x8 which is a little frustrating on an X570 board CPU 3900x Mobo: MSI MEG X570 ACE and also tried it with Prestige X570 Creation I only have a GPU card as well as the storage controller would really appreciate if anyone can help me out here - other then sell and get a Threadripper (which I would love, but....<$$$) thanks Henrik
You need to check your manual.... 2x PCIe 4.0/ 3.0 x16 slots (PCI_E1, PCI_E3) 3rd Gen AMD Ryzen™ support PCIe 4.0 x16/x0, x8/x8 modes 2nd Gen AMD Ryzen™ support PCIe 3.0 x16/x0, x8/x8 modes Ryzen™ with Radeon™ Vega Graphics and 2nd Gen AMD Ryzen™ with Radeon™ Graphics support PCIe 3.0 x8 mode* y 1x PCIe 4.0/ 3.0 x16 slot (PCI_E5, supports x4 mode) y 2x PCIe 4.0/ 3.0 x1 slots** * PCI_E3 slot is only available for 2nd and 3rd Gen AMD Ryzen™ processors. ** The PCIe x1 slots can not be used simultaneously. PCI_E2 will be unavailable when installing the PCIe card in PCI_E4 slot. ***The speeds may vary for different devices Pretty sure you can not run 16 + 16(4x4)
you could run the card in pcie x16_1 and the gpu in pcie x16_3, leaving _2 completely empty. gpu performance will take a big hit, but the AIC will run at x16 ... edit: its pcie 4.0 ... so not 100% sure about the performance impact ...
Hi The Goose, thanks for your reply I can accept that I can only have so many lanes (24), but I would like to be able to choose what use them for CPU 3rd Gen, so that should have cleared the first hurdle - only two cards, Storage and GPU, as well as onboard M.2 controllers and this is where I might be getting caught out! say we can only use PCIe 1 and 3 and theoretically I can have one @ 16 and one @ 8 PCIe_1 @ 16x - slot in the storage controller (if this is possible it should be happy and show all 4 disks) PCIe_3 @ 8x or even 4x for the Graphics card - I am not really fussed I take it the onboard M.2 controller also take up 4x lanes How do I know how many lanes I have assigned? sorry if this is vague question ;-) but I am not sure thanks again, really appreciate you taking the time to reply Henrik
Sorry for a late answer. Did you find a solution for this? But as for my late answer. Your X570 ACE may not have enough lanes if you already are using the onboard M.2 slots. Your PCIe slot E1 only works at 16x or 8x. And E3 only at 8x. When in use, your E1 and E3 will both run att 8x . Your E5 (bottom slot) only in 4x, and it runs via the X570 Chipset. And the Chipset the has only 4x lanes to communicate with the CPU. So if you already have a M.2 on the Chipset, and you also ad the graphics card in that you Will have a gigantic bottleneck in both graphic performance and storage performance. All your SATA ports, soundcard and USB ports also shares that 4x link! I am almost sure that what you are trying to is not possible even if it would work in theory. It is to much. Your choice of plattform was quite poor of you want to run so many NVMe SSDs. The X570 was never ever intended to run this many NVMe SSDs! TRX40 is the way to go if you need a lot of NVMe SSDs. Again, sorry for my late answer
Hi evronius thank you for taking the time to reply, much appreciated. It is very much as you say. I haven’t gotten a solution other than as you state move platform to TRX40 which is what I plan to do. I am Currently using three onboard drives and two on the AIC. Running with one boot drive and four in a raid-0 which isn’t running at full speed. Though it is still incredibly fast. I hope by the end of the month to have parts for a TRX40 to replace the X570, fingers crossed. thanks again for your time henrik
You can not do this on X570 unless you buy a super-duper expensive motherboard with a PLX chip on it, like used to be common to extreme-class motherboards in the late 2000's. This will be even LESS common going forward with Nvidia passing SLI support promise over to game development companies and not working on it at the driver level anymore. Please choose Threadripper TRX40 platform to do what you need. Threadripper Pro and 'regular' Threadripper parts have fundamental differences (such as OC support and memory channels supported) you must become familiar with before purchase. X299 Platform for intel chips is a 'dead end' platform for the most part and is not good value for the money except used (and does not / will never have PCI-E 4.0), to my best info. If it were me, I'd take two of the drives and leave them on the PCI-E host card, leave as many on the motherboard as possible, and get an PCI E X1 to NVME adapter card and run one of the drives at close-to-sata speeds (though IOPS will be better) on one of the chipset's PCI-E X1 ports. Those cards are cheap (less than 15$ USD), and this drive will be great for media storage, fairly responsive but not nearly the throughput. Make sure the card is PCI-E 4.0 compatible and if not, use PCI-E 3.0 on it. It should be fine. You can also use one drive as your external backup drive via USB 3.x, where it should run pretty decent though not what a PCI-E 4.0 x4 port would have given it (this may be measurably quicker than the last solution). Keep in mind RAID doesn't really 'improve' your access times and random IOPS, but it helps more in sequential large file transfers IF you have something else to read-write to that's as fast. RAID is honestly more of a pain in the butt than a reward especially with drives that can read/write in the 5~7gb/s range now, unless you need it for mirroring / redundancy. Or just continue to procure more parts for TRX40 and enjoy having a system that will be immensely more powerful than 99.8% of people would ever need, for years to come. Most SERVERS that are 2~3 years old are not that powerful as TRX40 can be. I have a 3950x and it's insanely more powerful than I need *MOST* of the time (game dev stuff here), so I can only imagine what having something 2~4x that chip would be like. Enjoy! Hey guys! Someone's buying a TRX40 system!!! *quickly invests in power companies and copper cable manufacturers* No really, Enjoy, and don't forget to come back and let us know how it went and what speeds you got (and a video of what happens to the power grid every time you turn it on or zip/unzip files).
thanks, appreciate your feedback, I am curious about what board with X570 chipset has the PLX chip on it? I will be going with option 2 - TRX40 threadripper. Then will have a garage sale for my X570 and 3900x (that is if my 3970x shows up in usable condition but I hope will be looking like this when it does ) moving the disks/drives around with two on the AIC and the other three on the motherboard, does alright for now, but still going for the TRX40 - I put the 6th disk on a USB-C but it max out at 1GB/s and worked out it also work on my ipad ;-) Hoping the TRX40 will be as kind to me as my EVGA SR-2 has been for the past 10 years - you can't have a computer powerful enough, it is a bit like saying, no needs more the 640k (just checking you know that line) It would be nice if we could run our computers on solar! ;-) in particular those of us who lives on the sunny side ;-) but will stay out of the politics thanks again for taking the time to reply H
Don't know the motherboard(s) name(s), but sometimes the highest-end boards on many platforms include these chips, it was not a garauntee (and I haven't seen them as much recently). You can feel free to have a look and peruse the various boards and see if you find something. Honestly though if you have the green backs (money), get the TRX40 and be happy with it. Those PLX chips can have weird latency issues and all that, so you're likely better off without it.
