question about mobo/graphics card
Considering that some of the graphics cards I've seen pictured these
days use two of the backplate slots to mount the card, have any motherboard manufacturers started offering mobos that are specifically desigend to accomodate two such cards. When I look at those graphics cards, it just seems like they would cover up so much of the motherboard that even having a lot of PCI-e slots is wasted and if one had two graphics cards, it'd be even more so. So I'm wondering if mfrs have begun selling specialized mobos catering to the crowd that wants to use say one or two graphics cards and at the trade-off of pci-e slots for other uses. Are there any buzzwords or special marketing phrases the mfrs use to identify such a restricted use mobo? Thanks, John |

Are there any buzzwords or special marketing phrases the mfrs use to identify such a restricted use mobo? Thanks, John Look at a pic of the mobo in which you are interested. You can see if the PCI-e slots have been moved apart farther; i.e., there are no slots between the PCI-e 16x slots (there might be a PCI-e 1x slot which means you lose it when installing a double-wide video card). I got the Asrock Z390 Taichi mobo. You can see a pic of it at: http://static.techspot.com/images/pr...17-product.png The top PCI-e 16x slot is for the [primary] video card. Notice the is a PCI-e 1x slot just above it. That will be available when you insert a single- or double-wide video card. The next typical slot would be down from the long slot but there isn't one on this mobo (that's where you see what looks like rivet heads). The PCI-e 1x slot below there is far enough down that it won't get blocked by a double-wide video card. However, if you install a card in that PCI-e 1x slot, you end up blocking airflow for the video card's cooling fan. That card would be only a few millimeters away from the double-wide video card which isn't far enough away to let air flow around the card even if it were a low-height card. https://www.asrock.com/mb/features/Z...20Ultimate.jpg That's another pic of that mobo. #9 is where is the PCI-e 1x slot and also the onboard M.2 NVMe socket for an SSD drive (as a PCB, not as a 2.5" or 3.5" case). #8 is the primary video slot. Below that is another M.2 NVMe socket for another SSD drive. The M.2 drives sit against the mobo and are lower than the height of the PCI-e socket, so they don't interfere with daughtercards. Below that is another PCI-e slot; however, with a double-wide video card in #8, its fan enclosure will be very close to that PCI-e 1x slot. I forget if the video card sucks in its side and blows out its backplate, or the other way around. I could test but it's not important to me right now. If I were to add a daughtercard into the PCI-e 1x slot (just below the #8 slot), I'd add a case fan in the side panel to make sure air got blown down between the PCI-e 1x card and the double-wide video card, but that would only work if the video card sucked in from its side and blew out its backplate. Alternatively, I'd check if the HDDs in the low-end drive cage were out of the way to let the front case fans blow across and into the small gap between the PCI-e 1x slot and its card and the very nearby double-wide video card. If I add a daughtercard what will use a PCI-e 1x slot, I'd first use the one above #8 with the video card. I haven't even checking how to use dual double-wide video cards with this mobo. The cost for such a setup would achieve miniscule gain. I also don't overclock or use liquid cooling (which has been proven to offer no advantage of proper fan cooling but might be quieter but still needs fans on the radiator; however, my fanned setup is so quiet that I'm still getting used to the silence). My choice is just one example. That mobo supports only 8th and 9th gen Intel i7 CPUs and Asrock only supports Windows 10 for that mobo. You asked if there were any. Here's one. I'm sure if you hunt around using your own criteria as to what you want for features in a mobo that you'd find many other candidates. |

Are there any buzzwords or special marketing phrases the mfrs use to identify such a restricted use mobo? Thanks, John Various platforms have different wiring patterns for slots. Even if all the motherboard slots look like PCIe x16, they can be wired x1, x4, x8, x16. Some users are not overjoyed to find their "SLI lookin" motherboard, has x16 for the video slot nearest the processor and x4 for the second large PCI Express slot. Even though both connectors are the same size, they don't have identical wiring. A PCIe slot can work if wires are missing (this even helps if there is a lane failure and you don't even know it has happened). An LGA1151 would be x16 and x4. An LGA2011 would have a total of 28 to 44 lanes with the possibility of more (real) x16 slots. So while you can admire pictures of products, you really need to download the user manual and find the "plain truth" chapter that gives all the population rules. It will tell you how the slots are wired, and what slimy thing they did to save a buck or two. Excess slots today are replaced with NVMe, as Vanguard mentions. And there are also interactions between those slots and maybe one or two of the SATA connectors or Express connectors. The end result, is a small nightmare in the manual, as you figure out whether the motherboard is a "good deal" or not. For example, if you put a 28 lane LGA2011 processor in a motherboard, chances are good one PCIe x16 doesn't work at all (no wires fed by the processor). While I think NVMe are "cool" to have, I'm not willing to compromise my setups on half-assed slot configurations. YMMV of course. Gimme seven slots and let me choose what to stick in them. Just about every computer I've ever had, has been full of cards, because I like "addons" as new stuff shows up. The latest card being an USB3.1 Rev2 card for an older computer. In addition to the USB3.0 card it had as well. If a fun toy is available for the right price, I'm not adverse to building up my junk room contents. Just for the record, SLI or Crossfire aren't the best deal in the world. They don't exactly double performance, and some titles perform relatively poorly that way. Perhaps a time you might need something like that, is if you had a VR headset and it needed "mighty horsepower" to work. But for gaming, you should be able to snag a single card with sufficient horsepower for a decent gaming session. Buying a couple 7300LE and slapping that SLI ribbon on them, is delusional :-/ Either you have the money to game properly... or you don't. Buying a couple 7300LE doesn't make you a gamer. You'll only get an extra 3FPS in the SIMS doing that. Having said that, you can imagine what my opinion is of builds with three or four massive video cards installed. That's OK if you're cracking passwords or mining Ethereum or something, but that's a giant waste for gaming. People who have that kind of money to spend, do benchmarks all day long. Paul |

The computer is an extension: It must be uncompromising to win. The nicest part is to suppose that $500 case is an adjusted cost for an eighth of what each $2000 videoboard costs to pair them. How could anybody but a chump not put the neon lights underneath a car he lives paycheck to paycheck for. |

I upgrade my mobo and eqpt infrequently. What I've got now works fine for my needs, but it's not particularly suited for the newer tech. John |

My existing system works very well for my needs. A new graphics card sounds tempting at times, but the price (and I suspect the h/w requirements) of the cutting edge graphics cards are way to rich for what I do. If I do upgrade my mobo, it would be not so much for a graphics card but something related to faster data transfer speeds to storage devices or communications like wi-fi or bluetooth capability.

I also wanted the graphics card upgrade, thinking, at the time, advancements for that provision in MB technology an optimistic bet. But the costs, at what I'd imagined surely over time by then a value, were not especially a benefit over video-chipped motherboards I've been running since, near the same time, first PCI-E slots became available for better graphic boards. My price expectations ended up being neither a realistic one for a value or appreciable performance. Something, though, I already knew, that they neither could be, any more so, had I found a theoretical better value on a better board: I'm not enough of a gamer, so there's really no bottlenecks involved with thruput for more common uses, such as occasional light-weight games or a video renderer for encoded films off that videochip soldered onto a MB. Something for nothing can indeed sometimes work, just not all the time. |
