even just a few bios setting can boost performance, but that would require experimenting. Ive seen my share of bottlenecking with high end gpu’s. There is no reason why lower PCIe bandwidth should significantly impact performance and I have never seen anyone demonstrate otherwise.Īs for “budget components”, how would these impact performance besides the lower amount of PCIe lanes? I’m not saying it can’t be happening, but I’m not just taking your word for it. There’s also very little communication between the GPU and CPU during rendering. When using multiple GPUs with Cycles, there is no communication between them whatsoever. Unless you provide some sources for these claims, I’m just gonna say these are things you simply believe without any real foundation.ĬUDA doesn’t need or use SLI and it’s generally recommended to turn it off.

theres a good chance you wouldnt get the full speed of the 1070 any way, due to budget board components.

This revision includes support for PCI Express implementations conforming to the PCI Express Base Specification, Revision 2.0 and implementations conforming to the Universal Serial Bus Specification, Revision 3.0. though in theory pcie speeds dont matter much, the board isnt rated for sli, which means 2 gpu’s would likey cause stability issues, or simply not work. The PCI Express and USB SuperSpeed PHY Interface Specification has definitions of all functional blocks and signals. Thats looks like an budget board, i dont recommend putting two cards in it. Two 1070s will have better price/performance than one 1080, but they’ll also consume more power and produce more heat. Looking just at PCIe bandwidth, I’d say no. Is it a more valid approach to buy a more powerful GPU (eg.1070, 1080) and use one instead of two? You may want to ask that community how much impact PCIe bandwidth has in practice. I’m only aware of one GPGPU render that does this, which is Redshift. In the future, Cycles may implement streaming data in during rendering, easing the memory limit but increasing the stress on the PCIe bus. However, Cycles also needs to fit the entire scene into GPU memory, otherwise rendering will fail. Right now, Cycles only does GPU transfers on load and during image updates, the PCI bandwidth is a negligble factor in both cases. I can’t find if the same is true for Cycles or other GPU render engines. The difference is in the load times (usually negligble) and the per-frame transfers (different for every game, but usually a small factor). It usually is, because for best performance, you’d want to minimize PCIe transfer while the game is running. Tektronix’ Solutions for PCIe 3.0 Base Spec Testing Tektronix DPOJET PCIe 3. I’ve been searching through Internet and a lot of people claim that the performance bottleneck is neglect-able at least in games. However, you’d still have to take into account the amount of lanes provided (i.e. If there were really two different versions on your board, that means the theoretical bandwidth per lane for the PCIe 2 would be only 500 MB/s vs 985MB/s for the PCIe 3. It is also possible to drive an x16 GPU on an x1 slot using an adapter. It’s common for motherboards to have two x16 slots, but only one is wired to use 16 lanes and the other uses only 8 or 4 (x8 and x4). Most motherboards only have PCIe x1 (very narrow) and PCIe x16 slots (very wide). That sounds odd, which motherboard is this? Are you sure the slots have different PCIe versions?Īlmost all GPUs require PCIe x16 slots to physically fit. The problem is that my Mobo has only 1xPCIe 2.0 and 1xPCIe 3.0 slots.

I know that there is almost no performance gain with running in PCI 3.0 but I would like to know why it doesn’t work on a 8D board while it did on the Plus board.Hi all, I was thinking of pairing my GTX 970 4GB with another GPU most likely a GTX 1060 6GB. I can only reset it to normal by using the Clear CMOS button but then it’s back to PCIE 2.0 x8. My system runs but I get no video signal. When I enable PCIE 3.0 in BIOS I get a black screen. Everything runs fine now - Win7, gaming (GTR2, rFactor, pCars, GPL), MS Office, Adobe CS6 - but here is my question/problem:Īlthough all components should be PCIE 3.0 x16 compliant/compatible my system runs in PCIE 2.0 x8.

So I switched the board, did a clean Win7 install and updated the mobo drivers via Live Update 6. After a long search I found an almost identical board, an MSI X79A-GD45 (8D). So I needed to be replaced it but couldn’t find the same board anywhere around the world. Worked perfectly until 2 months ago when my mobo died due to an (accidentally) wrong BCLK setting.
