Will this board receive PCIE 4.0 with a bios update? It seems the x470 can support it, I found this on tom's hardware: "But after speaking with several motherboard vendors here at CES 2019, we've learned that many of them have successfully tested PCIe 4.0 on 300- and 400-series AMD motherboards, meaning that the feature could be enabled with a simple BIOS update, at least partially. Our sources tell us that after unlocking the feature via a BIOS update, the older motherboards supply a PCIe 4.0 x16 connection to the first slot on the motherboard, but the remainder of the slots revert to PCIe 3.0 signaling rates." Hopefully we get Ryzen 3000 support along with PCIE 4.0 ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |

| Would be nice, but I still want to see a GPU card that can saturate the current PCIe bandwidth. |

Gigabyte Enables PCIe 4.0 on X470 and B450 Motherboards (Updated 05-19-19) From Tom's Hardware: " The company has enabled the option for PCIe 4.0 in the BIOS of its X470 Aorus Gaming Wi-Fi 7 motherboard. That signals that, under some circumstances, the company will likely support PCIe 4.0 on existing motherboards if you drop in a new Ryzen 3000 processor." Now I'm hoping ASRock has something for us to unlock PCIe 4.0 on x470. ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |

I would imagine the major factor will be data path compliance. Think of it like network cables, even if your switch and device both support gigabit speeds, you can be restricted by the cable you use. Odds are, most boards will support it if a 3000 series CPU is installed (with supporting BIOS). It should be no different than PCIe 2.0 on Sandy Bridge being upgraded to PCIe 3.0 on Ivy Bridge with a BIOS update and CPU upgrade. I am sure we will know more soon but for now, my guess is that if one manufacturer claims support will be added via CPU and BIOS then all manufacturers will. -------------

Yes I also hope soon we have news if they will have PCIe 4.0. I'm certain the x470 boards will support the 3000 series CPUs I'm looking to upgrade my 2700x to a 3700x :D ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |

By the way, AMD had earlier confirmed <https://www.tomshardware.com/news/amd-ryzen-pcie-4.0-motherboard,38401.html> that current 300 and 400-series AM4 motherboards can support PCIe 4.0 but has left it to the motherboard vendors' discretion whether or not to implement the feature. The slot selection for Gen4 support will also depend on the board's layout and PCIe lane lengths. Any PCIe slots with PCIe 3.0 switches or extra routing will not be able to support Gen4 speeds. https://www.tomshardware.com/news/amd-ryzen-pcie-4.0-motherboard,38401.html Most important, so far no gaming graphics card supports the faster standard on the market. We will verify this function upon receiving those PCIE4.0 devices in our lab. ------------- Kind Regards, JZ https://shop.JZelectronic.de - Der Shop mit ausgesuchter ASRock Profi Hardware https://www.facebook.com/asrock.de |

Hello, yes I read that article as well. This is indeed good news, and future proof for when graphics card do ship with pcie 4.0. Now I see the 3800x is part of Ryzen 7 not Ryzen 9 as previously reported. Now I will upgrade to 3800x, to replace my 2700x. It also has really good single core performance which I like as well. Reason I play a lot of the MMO Guild Wars 2 and that game is single core heavy. ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |

I just saw that the x470 Taichi received a new BIOS update to v3.40 Is there any confirmation that it unlocks PCIe 4.0 on the first slot? I don't see any information posted if it does or doesn't. ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |

Take a look at the Computex coverage of X570 boards. From what I can tell it seems unlikely we will see PCIe 4.0 support on gen1 and gen2 boards. Bare in mind this is based on personal observation, my contacts at ASRock have not provided any info on the matter as yet. Based on the design of the new boards and the need for active cooling on the chipset I get the feeling PCIe 4.0 is pushing the chipset to the limits and as such generates a lot more heat than can be passively dissipated. In addition to that there is also talk about the actual PCB pathing for the slots needing to be within tolerance. Ryzen 3000 CPU support is going to happen but PCIe 4.0 I get the feeling will not on older generations. That said, the only devices even able to leverage PCIe 4.0 to any degree are ultra high end NVME storage devices. GPUs can't even saturate x8 PCIe 3.0 yet so in other words, they will need to double their bandwidth requirements before they even come close to needing PCIe 4.0 bandwidth. So either GPUs will become less efficient in how they handle data throughput from the GPU to RAM and CPU or we will need to see double the raw performance. It will likely be the first as it will allow GPU designers to forgo a certain amount of optimization in favor of performance upticks. I would hazard a guess that it will be at least 3 generations of GPU from now before we see the need for PCIe 4.0 from mid range up, 2 before we see flagship GPUs come close. -------------

Yes I have seen the AMD keynote and saw a lot of x570 boards, also been following Gamers Nexus, Pauls Hardware, JayZTwoCents etc. The x570 boards come with cooling fans, and do make more heat. I mostly game so your right PCIe 3.0 is more than enough for GPUs probably until 2021 would be my guess. PCIe 4.0 is mostly for m.2 ssd storage. I'm more than happy with my m.2 ssd I have no need for faster than Max 3,500 MB. I'm using a Samsung 512gb Pro. I read PCIe 4.0 is supposed to to go 5,000 MB / sec but I'm good :D It's just that Gigabyte Enables PCIe 4.0 on X470, I guess their x470 line can handle it. I'm just happy I can upgrade to a 3800x CPU in 2 months. ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |

I guess we will see after launch. If one manufacturer enables it, others will too but the key will be stability. If I were responsible for the decision I wouldn't enable it, better to have customers with stable systems than angry customers because it didn't work right. I have a sinking feeling it will probably be enabled on a number of boards, and likely cause problems  -------------

Yes still to early since the release date is July 7th for the 3000 series. But I'm sure some will get the CPUs earlier for review, unless AMD won't let them before the release date. We shall wait and see if it is stable at PCIe 4.0 if it is enabled. ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |

To be honest I don't see this as a big deal. PCIe 4.0 does very little to help current PCIe add-in cards, even GPU's. IMO the main benefit at least in the medium term will be more bandwidth to the chipset, so that the chipset can feed more ports of all types without saturating the link back to the CPU. I'd be surprised if the X470 chipset has the ability to talk 4.0, or the excess capacity to make use of it. (I suppose that PCIe 4.0 to NVMe SSD's is another potential benefit, and that would be nice, except that transfer time isn't the overwhelming majority of total time that it is in the HDD world.) |

I have to be honest, I am not dissapointed that PCIe 4.0 will be restricted to 500 series chipset boards. AMD's track record hasn't been smooth as it is, throw in a new PCIe standard on boards that were not designed for it and you are asking for headaches. The key problem is that AMD don't design the boards and board partners can't predict what will be coming in a generation or 2. Don't get me wrong, AMD are doing a great job shaking up the market but they have teething problems to iron out. Intel have had a lot longer and a lot more budget to iron out their launch cycle. When you consider that Intel's architecture is largely unchanged since Sandy Bridge it becomes clear why AMD, on it's relatively new Zen platform, has some catching up to do. PCIe 4.0 at present only benefits high bandwidth applications and as it stands, the only practical application is with storage. On the GPU front, PCIe 4.0 is overkill in the extreme right now in all but one way; a x1 PCIe 4.0 slot will be equivalent in bandwidth to an x4 PCIe 2.0 slot where it comes to bandwidth. In theory that could mean we might see SFF GPUs on x1 PCIe slots, all the way up to about the performance of a GTX 1650 before bandwidth bottlenecks make it impractical. If x2 slots (or at least x2 wired slots) become a thing that could go even further. Once we start seeing low tier 500 series chipsets I could see the SFF market exploding with options. -------------

Does this really matter to anyone ? Atleast it shouldn't at this point. It's not like any video cards or other hardware sold now, that any of us can buy are PCIe 4 cpapble and require it to work. |

Yes I agree. After reading many threads on PCIE 3.0 with graphics cards, they barely even use all the bandwidth of PCIE 3.0, unless maybe with 2 GPUS running in SLI at 4K with say 2 RTX 2080ti's or higher. If your using 1 GPU now or in the future, we are all fine for I would guess maybe for 2-3 years more before we see games demand more bandwidth from PCIE. For now it's all about storage. I read that PCIE 4.0 can hit 5,000 MB/s. I'm more than fine with my 512GB 970 Pro. I get 3,566 MB/s read & 2,330 MB/s write. No point to upgrade for 1.5GB more bandwidth that would be a waste of $$. I'm happy I can just buy the 3800x and drop it in my x470 ^_^ ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |

dunno why you guys still talking about gpu and pci-e 4.0 the gpu's barely fully use it its more about storage like the upcoming corsair MP600 alone does 4950MB/s (R) & 4250MB/s (W) my m.2 slot maxes out at 4000MB/s gen3 X4 imagine those in a raid card on a full X16 slot -------------

And here is the final say from AMD themselves, from reddit Robert Hallock: "This is an error we are correcting. Pre-X570 boards will not support PCIe Gen 4. There's no guarantee that older motherboards can reliably run the more stringent signaling requirements of Gen4, and we simply cannot have a mix of "yes, no, maybe" in the market for all the older motherboards. The potential for confusion is too high. When final BIOSes are released for 3rd Gen Ryzen (AGESA 1000+), Gen4 will not be an option anymore. We wish we could've enabled this backwards, but the risk is too great." https://www.reddit.com/r/Amd/comments/buydi6/amds_robert_hallock_no_pcie_40_support_on_300_and/eplj20j/ So that's that. :D I'm fine with that. On another note I just seen the x470 get a new BIOS v3.43 Ryzen 3000 support and Enhance AMD XFR 2.0 function; change AMD PBO rule with Pinnacle CPU. Support SMT mode disable. ------------- x470 Taichi v5.10 5800X3D (Scythe Mugen 5 Rev.B) G.SKILL Flare X Series (8GBx4) 32GB 3200 CL14 970 Evo 1TB+SK Hynix 2TB PNY RTX 4070 Super SoundBlaster AE-7 EVGA 850W Platinum LG WH16NS40 AOC Q24G2A |
