Greetings, First system I have built in a while and wow things have changed. I can't get video out of any of the ports on the graphics card. I've tried every port on the back of the card. I've tried different external cables/monitors, power supply port/cable. There's only one PCIe 16 slot and it's in there. Reseated, examined the pins and the slot, don't see any damage. I do not have a speaker yet, nor did the board come with a CMOS jumper. I don't have a source to cannibalize one either. Both are on their way. In the manual, it says just to short the CLRCMOS1 pins for 3 seconds. I have tried that and it didn't change anything. I found an ASRock video on youtube that mentioned jumping it, pushing and holding the power button for 10 seconds and then leaving it alone for 15 minutes. It sounds suspect, but at this point, I'll try anything. In the meantime, I figured I would try and find definitions of the red LEDs behind the DIMM slots. I found section 2.7 of the quickstart guide. It's an interesting paragraph, but doesn't help a whole lot. Also, once the speaker does get here, I can't find the beep codes. I found a generic list and GPU is not on it. So that's what I am looking for: 1 - Meaning of the LEDs on the motherboard 2 - Where is a list of beep codes? Thanks in advance for your time.

Is your video card known good? Tested in another computer? Temporarily remove the NVME and three RAM modules; see if it will POST and give video. Jake ------------- Asrock X370 Killer SLI/ac, Amd Ryzen 7 5700X, GSkill Flare X F4-2400C16D-32GFX, RaidMax Thunder V2 735W PS |

Hey Jake, No, brand new out of the box. I don't have another machine with a PCIe X16 slot (thus the upgrade :) ). Removing the components sounds like a plan. I will give that a shot as soon as I can. Thanks for the response! T |

Beep codes: https://www.asrock.com/support/faq.asp?id=286 As Jake noted, try with only 1 module of RAM, the GPU and CPU. Remove all other devices from the system (you can just disconnect them, you don't need to remove them from the case). Make sure both your 24pin and 8pin CPU power cables are properly connected and that the CPU 8pin is in fact the CPU 8 pin (4+4) not a PCIe 8 pin (6+2). -------------

Hey everyone, Thanks for the responses, much appreciated. Really appreciate the link to the beep codes. I checked and made sure, I also swapped out the CPU 8 pin power cable, they're both labelled "CPU" and all 8 pins are populated. The only power cable not swapped out is the 24pin ATX cable because the power supply only came with one. 1 - So, with only one stick of RAM, in A2, I think that's correct with the 3600 processor, NVMe removed, GPU installed. The LED behavior has changed. On power on, The VGA and BOOT LEDs come on. After a few seconds, the CPU and DRAM flash a couple of times. After a few more seconds, the fans on the GPU go high and then low and the VGA and BOOT go out as well. After about 10 seconds they are all out, GPU fan on low. 2 - With everything installed, everything was the same except the end result is the VGA and BOOT LEDs stay lit solid and stay that way until system reset. 3 - With nothing installed except one stick of RAM, no GPU, no NVMe, the behavior is similar to bullet 2 above, except the BOOT LED goes out for about two seconds, then comes back on solid, and both VGA and BOOT stay lit until system reset. Thanks again for your time and effort. The speaker will be here Thursday. Still no luck finding a jumper for the CMOS reset. Also found the sticker everyone has mentioned on other threads, it says P2.20. I know it needs to be updated, but I can't do that unless it at least boots to BIOS. T |

You can either take a flat head screw driver and touch both pins on the "CLEAR CMOS" pins .. or just pop the battery out for a few minutes .. to reset the BIOS to defaults. ..and .. if you haven't already .. if it still doesn't boot after resetting the BIOS .. try each stick of memory separately ------------- |Ryzen 5 5900|ASRock X570 Taichi-BIOS 4.60|2x16GB HyperX Predator RGB 3200@3600 1:1 IF|ASRock RX 6700XT|2 x PCIe 4.0 M.2 Drives for OS & Games|850 WTT Seasonic 80+ Titanium PSU|Noctua NH-D15| |

Have you tried a different display cable? -------------

I've tried both different power cables to the GPU and output cables to the monitor, both displayports, the HDMI port and verified the monitor is good. I've tried two different displayport cables, I know the HDMI cable is good. I do not have a DVI cable to try that output. I haven't had a chance to check each stick of memory. I don't understand why that would work when the LEDs don't point to DRAM but I'm willing to try anything. Thanks so much for the responses. I will keep plugging away. T |

try using one of the lower pcie slots to test .............. i recently had an issue whereas the top slot was locked in bios to auto which was clashing somehow with the gpu using the lower pcie slot allowed a boot to bios and then changing the pcie option to forced gen3 made the top slot work sounds crazy i know ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

Hey Datonyb, thanks for the response. Can you put a PCIe 16 card in a smaller slot...? I've read arguments on both sides and I am totally hesitant to modify a brand new mobo for testing purposes. Going to check and see if the smaller slots have open backs... Confidence is low though. I am waiting for the delivery today of the speaker and the jumpers. Tomorrow the HDMI cable arrives. Going to keep trying. Thanks again for all of the responses. T |

Your board has 2 PCIe x16 length slots, try in both. Do NOT alter your PCIe x1 slots. If you do it will void your warranty and if you have any issue with your board after the fact you will not be able to return it. -------------

Thanks, Xaltar, not sure why I thought that was x8 slot. I read somewhere the first slot should be used if available, but like I said, I'll try anything. My case has the bend out style back planes and the mobo is in the way... :( I also don't have replacement blanks to put back in there. Man I miss my old desk at work, I had all of this kind of stuff laying around. The struggle continues. Thanks for the great ideas! T |

The slot is x4 electrically but it is physically an x16 slot. This is common on many motherboards. Any PCIe device will work in any PCIe slot (electrically) so there is no need to provide x4 and x8 (physical) length slots, these largely only exist on server/workstation boards. Even a PCIe x1 slot can be modified to accept a PCIe x16 card (what I thought you were referring to) by opening up the back with a sharp blade (cut away the blockage making it open ended). It voids your warranty but many people have done this for mining systems etc. I have a board with an x16 (physical) slot that is electrically an x1 slot for example. Long story short: If the GPU fits in it, it's safe to try it. -------------

the break out tabs should come off with just a little wiggle back n forth there should be enough room between the board to bend it back n forth a little to break it away just another quick thought your not using any type of adapter on the gpu outlets? eg a dvi-vga connector or anything? this can cause issues basically with am4 you need to be using hdmi or displayport direct from gpu to monitor it seems theres some sort of clashing with adapters from gpu output to monitors (allthough say an ancient gpu with native vga seems ok to native vga monitor, hence why its the adapters/conversion i think causes the problem) ------------- [url=https://valid.x86.fr/jpg250] [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

Thanks datonyb. I think I'm going to be able to push from the backside and do the wiggling outside of the case, it's more difficult than I would have thought. There are no adapters on any of the video cables. The monitors are brand new out of the box as well. Thanks again! T |

Well. You guys aren't going to believe this. After doing all of the testing suggested by everyone (thank you so much!), with the speaker installed, still no video out. I was going to give up until I realized the HDMI cable had been delivered a day early. I plugged it up, not expecting much, lo and behold, there's video on the display port. I checked the HDMI, there's video there too. I check the other DP, there's video there, too. I was beside myself. Powered it down, reinstalled everything and tried again. Nothing. I realize I forgot to plug in the HDMI (wasn't part of the routine yet). I power down, plug in the HDMI, we're off to the races. I verified it. After power being removed, the DPs aren't active unless there's an HDMI cable plugged in. After the first time, it's irrelevant, you can remove the HDMI and reboot, restart, power down, etc. But if you pull power from the supply (or turn the supply off) the DPs do not function. Sorry for the wall of text, I just don't understand or how to fix it yet, but I'll try that tomorrow. Thanks so much for all of your help everyone!! T |

try checking the pcie option in bios if its set to 'auto' change it to gen3 unless your using a amd 5600/5700 card of course ..........yet i doubt the gen4 will make any difference to gen3 ------------- [url=https://valid.x86.fr/jpg250] [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |
