    Setting up NVLink with 2x 3090 FEs

    Unfortunately, that's not the case. Gen 4 will not work if the cards are on the cables. But both 3090's work perfectly in Gen 4 when directly on the motherboard socket: I just tried again a moment ago and confirmed it. The drivers only load when forced to Gen 3. Gen 4 with cables immediately...

    Setting up NVLink with 2x 3090 FEs

    Well honestly I'm a bit pissed. This was all a software issue. This entire time. There's nothing wrong with the sockets, cards, or cpu. I didn't need to order a $800 mb. Just a colossal waste of time. First, I have to say that I've already tried all of these steps before. But something about...

    Setting up NVLink with 2x 3090 FEs

    Just to make sure we're all on the same page... I'm talking about the pins inside the slot. In the socket. Things are going down hill here. Now I can't get either of the 2 x16 slots to work. #2 and #4 are OK. #1 and #3 will boot and show video but the driver won't load. Tried both 3090s. Same...

    Setting up NVLink with 2x 3090 FEs

    The 3990x is using ~600W in the current config with all 128 threads firing on a render. I'm planning to overclock further in the future. Then 350w per 3090. So I'm already at 1,300 watts before any other HDD or raid are factored in. Even at 1,300w I'm starting to push the margins for continuous...

    Setting up NVLink with 2x 3090 FEs

    Using the 3990x threadripper. Latest bios. I'll try a few more things today. It's starting to look like I've managed to cook a PCIe x16 slot. How do you even do that? With all other PCIe slots empty... It will boot with a 3090 in #3 and I'll get basic video. But device manager always shows a...

    Setting up NVLink with 2x 3090 FEs

    You could be right about that. I just checked the speeds and they were not matched. So I looked at the manual and I misremembered. SLI is meant to be on PCIe_1 and PCIe_3. I was using PCIe_4. So I moved things around. Set them in PCIe_1 and PCIe_3 as the manual suggests. Once I booted up the...

    Setting up NVLink with 2x 3090 FEs

    I've been searching for a bit but not having much luck. With the old SLI setup there was a tab in NVIDIA Control Panel where you could configure SLI. But I can't find anything like it in the new version. The two 3090's are installed. The NVLink bridge is connecting them. Is there any software /...

    3990x overclock. Pushing it a little harder?

    One extra radiator and my cinebench R20 score went up by 1,000 points. Temps went down to ~68c from ~72c. But I'm still capped just under 4 ghz. Just not breaking above. It's getting cooler but not much progress. Posting full Ryzen Master screenshot.. If anyone sees anything off in there feel...

    3990x overclock. Pushing it a little harder?

    Agreed. 4.7 is out of the ballpark. I built it up to remove all the bottlenecks I could think of. But I'm hitting a wall at the moment and the components are not reaching the full potential. Stuck. So I've done all my configurations in the bios and just use ryzen master to monitor the hardware...

    3990x overclock. Pushing it a little harder?

    Is there anything I can do to push the 3990X a little more with PBO? I'm trying to inch closer to 4.7ghz all cores (wishful thinking). At the moment I can't seem to break the 4 ghz barrier. ROG Zenith II Extreme Alpha 3990x G.Skill Neo ram (2 channel now - waiting on 4 channel) 1600W PSU...
