Dash8Q4Hello,Last month I picked up my ftw3 ultra 3080 from canada computers and I have been loving it. I installed a Barrow waterblock last week and a riser cable to have it vertically. I initially had issues since the card is pcie 4.0 and so is the motherboard, while the riser cable was pcie 3.0. Eventually I was able to get into BIOS and change the speed to gen3. This lead me to check if the card was running at full bandwidth and what do you know, it only runs at x8 no matter what I try. I have updated BIOS, bought a pcie 4.0 riser cable and still runs at x8(but 4.0). I thought it was the motherboard but I grabbed my 2080 super from my other system and put it on and it runs at x16. Meanwhile the 3080 ran at x8 in the other system as well. I've tried it with just the OS drive(all satas and second m.2 off) and nothing too. I'm at a loss of ideas on what to try so I wanted to stop by here before I start a ticket with technical support.Here are my system specs:Ryzen 7 3700XAsus X570 TUF Gaming Wifi16gb DDR4 3200CL14Gen 3 m.2 1tb(games)Gen 2 pcie ssd 256gb(OS) I tried this drive in both the pcie card and in a m.2 slot since its a plextor m.2 in a pcie card2TB Samsung QVO ssd for games1TB HDD/4TB HDD/6TB HDDRunning a 1440p IPS panel and a 1080p vertical LCD
Dash8Q4I tried without the riser and also put it on my second system(different motherboard and cpu) and it also ran at x8. @nosomo as I mentioned in my post, I tried with just the OS drive which is the pcie m.2 drive, in all configurations(m.2_1, m.2_2, pcie x16_2). The board has two m.2 slots and I read the manual, there is no indication anywhere of a slowdown, only when running two GPU's or if using the second pcie instead of the first one. As I said earlier, I ran it directly connected to the board, with only one drive in the system which won't reduce the lanes and nothing. I even put in my 2080 super in the system with all four sata drives and two m.2s and this card ran at x16.
Dash8Q4@ thanks, I will try that tomorrow.@nosomo, I manually set the bios settings to run slot 1 at Gen 4 and slot 2 at Gen 2 since my pcie ssd is a gen drive(Plextor m6e) and still getting x8 on the speed. I removed the card and took a couple of pics to check for straightness and it seems ok to me.I'm not too too worried since pcie 4.0 @ x8 is still substantial bandwidth for 1440p and even 4k; based on some benchmarks I've read online the drop in FPS is 1-2 haha. But I don't want to run into more serious issues down the line. I just wanted to see if anyone had run into this issue in here and generally just chime in, in case I was missing something. I had to crop the photos so I could meet the 500kb limit but it looks pretty straight to me. Sorry for the blurry one but you get the point.
KylearanThat's RMA worthy.Another user had his card running at 8x also, but that's because he scratched the traces by the PCIE slot by an accident when removing a heat block. One of the scratches was actually severed (no continuity), while the others still showed continuity. That's what caused his card to be stuck at 8x. Check the PCB for scratches coming from the PCIE Slot gold fingers. If this can't be fixed by a clean with Deoxit D5, RMA it.
Dash8Q4 edit: look what I found. never mind, just saw some pictures online and the card comes with that pin shortened. I can't see the back now but I suspect no scratches.
Dash8Q4I get 16 lanes gen 3 with my 2080 super which I plugged in a couple of days ago to rule out the motherboard.Yes, all in auto still runs 8 lanes.PSU is a 760watt Platinum Fractal Design Ion+ and the gpu is connected via sleeved extensions, I tried connecting directly to the PSU and same result. I have three separate pcie cables running off of the PSU, no daisychain or pig tailing going on. I will try those steps this weekend. Other users with the same motherboard in another forum don't seem to report issues with a 3060ti and both m.2 slots populated.I haven't noticed any damaged pins but I will check this weekend also. I'm usually very meticulous with my PC and do things very carefully, always keep it clean and well taken care of. Maybe it is a defective video card but I don't know about sending it back for a replacement as the stock heatsink fan connectors's clamping clips broke off when I was carefully pinching them to remove. With this said, I'm afraid of getting a warranty claim denied for something like this, which is totally unrelated to what possibly could be causing the problem. Shipping from Canada will cost a bit, not to mention the inconvenience of not having my main system card. In the end, the bandwidth at pcie 4.0 8 lanes is sufficient but again I will see what EVGA says(I've started a ticket with them already).PEBCAK hahaha Thanks for your input, I'll troubleshoot some more this weekend and get back if something changes.
SaaapHi!Did you finally found when it comes from? I have the same problem with my ftw3 3080, I tried a few things but I have to put this card in another pc to check if it works well. I want to be sure the card is the problem before RMA it because I was very lucky at the silicon lottery
micfogasJust wanted to add that I haven't solved the issue with mine. Currently, my 3080 ftw3 ultra only registers at PCIe 3.0 4x. I've reseated, running latest bios on both motherboard (z390 dark) and video card. In my case it's possibly the motherboard. I had to rma it for something else. I'll be bench testing today to find out. Hope it's not the video card but... 🥺 I guess this is happening a lot with this card? Not getting full lanes to be used? Sigh...
Dash8Q4SaaapHi!Did you finally found when it comes from? I have the same problem with my ftw3 3080, I tried a few things but I have to put this card in another pc to check if it works well. I want to be sure the card is the problem before RMA it because I was very lucky at the silicon lotteryHey, No I didn't find out what the issue was. It definitely wasn't the motherboard as a 2080Super runs all 16 lanes. I re-seated the gpu, cleaned the pci connectors with alcohol, looked at them and the motherboard slot as well and nothing out of the ordinary. I decided not to RMA it because I have not seen any performance degradation in the only game I've been playing so far. It would be too much of a hassle to send it to EVGA since I have it watercooled and don't want to be without a GPU for several weeks. I don't think it's worth it to be honest, the bandwidth of 8 lanes at pcie 4.0 is just as high as 16 lanes pcie 3.0. I only play at 1440p so that won't be an issue any time soon. If you live in the US maybe it's easier for you to send it in but I live in Canada. Good luck
