content: Been given a non workingASUS STRIX GeForce GTX 970which gives a video post error of 1 Long 3 Short. It apparently was working fine when removed but it's former owner could not get it to post so has moved on.I'm initially suspecting power requirements, noticed it has only an 8 pin power connector, a solid white led near that was on. The specs say up to 225W, not sure how much of that to post. The current card I have installed requires 250W on an 8+6 pin connector and works fine.Havn't torn it down yet, am looking at picking up a PCI extender, how long can I reliably go? Any good brands?Got any ideas on what to try out on this card first?

content: They came with proper length alreadypretty much well built ive seen... from AliexBesides you can power it up with external PSUwith proper CV/CC modes limits which will by all meanshelp in case of some dead short not seen (wo the foldback of ATX)There is not a huge list - the top 3 should be finePaul

content: and for the record - if you are serious about the beeps (no jokes)the typical 1L + 3S only fits AMI memory errorbut that changes **ALOT** including among vendors /versionsbest guessPaul

content: Quote from: PKTKS on April 03, 2019, 03:55:55 pmAccording to the ASUS EFI BIOS the beep code is - no VGA detected (which makes sense). The PC still boots past it just without any video.The history of the card suggests it isn't faulty, but this is the second system it won't post in now. I'm going to perform a bios update on this motherboard and also try see if it will post in a newer motherboard just to be sure it's a real fault I'm looking at.I had a look at PCI extenders and I will start with a cheap USB cable variety, I assume bandwidth isn't going to be an issue anyway. If you or anyone else have a suggestion or link to good extender for repair type work please post it. I need something to make it a little easier to work on.

content: Check again ... carving some tip if that BIOS is not from one of the3 great ones.. AMI Award or Phoenix...Usually ASUS, ECS, MSI, Gigabyte they don't write BIOS.They use those 3 big players ready ones. Which btw arealways updated on a regular basis on their web... (the pcb fabs)It helps just in case you want to follow the beeps.Otherwise a POST card is far more reliableas suggestions .. they are pretty much sameregarding good construction and no fab defects..cheapos are always 50% chance.. but they do work just fine

content: and if you have no real clue on the UEFI thing about the BIOS vendorbut you have access to a decent OS you will find that handy sometimeshost@\> dmidecode | grep VendorVendor: Award Software International, Inc.the thing is really crammed into the flashthe fancy UEFI screens are just for the sake of the eyes...Paul

content: Quote from: PKTKS on April 04, 2019, 04:34:43 pmIt's made by AMI according to the updated ASUS EFI BIOS I downloaded.It's 100% no VGA detected. Not only is it written clearly in the manual I have another identical motherboard that detects another faulty GPU and gives the same post beep code. Both motherboards are working perfectly and have been running for several years without fault and only produce this code when a suspect GPU is inserted.You will find it eventually by googling as well.

content: Oh well another uneventful ending didn't have to pull it apart, ending up being slightly dirty contacts. Posted immediately and tested it for roughly 8hrs and didn't skip a beat. Didn't even get to make my test rig.

content: I never trust the beeps.They have changed the codes so much in last decadesmaking that a challenging puzzle. I rather preferto stick a POST card which is far more reliable.Even though the "memory errors" also appearssince the advent of the UMA design. The IGPU sharedmemory always triggers that whatever problem it foundsbeing dirty, bad clock or just another thing.the beeps will not issue a "video error" (aka IGPU) instead theywill point to the "(shared) IGPU memory error" not being ableto distinguish that allocated poolGood POST cards will not do that simplificationPaul
