We and my team faced several challenges with a single streaming PC used for our business. Initially, we had two identical machines: a Ryzen 5 5600X with Gigabyte Aeris DDR4-3000 CL16 2x8GB MSI B450-A Pro KFA2 RTX 3070Ti SG Crucial P2 500GB and a 12M 750W power supply. The setup was quite stable, but recently one PC stopped responding entirely, which was disappointing given the investment made by customers who paid for recording and streaming services. We usually keep both units on site, allowing us to swap out the faulty one when needed. Once repaired, we inspected the PC and discovered the GPU was defective—it didn’t function even in the other machine, and the mounting hardware performed poorly. Consequently, we ordered a Gigabyte RTX 3070Ti GAMING OC and a Ryzen 7 5700X as replacements. After a few days, both components arrived. We began swapping out the CPU and GPU. Initially, powering it up failed, triggering an error LED on the GPU. Replacing the old GPU partially resolved the issue; the Desktop and FurMark worked again, though they occasionally crashed. We tried booting it up, but the error persisted. Inserting the previous GPU restored partial functionality, including Desktop and FurMark, albeit with occasional hard crashes. Since we hadn’t replaced the motherboard yet, a colleague suggested the MSI MPG B550 Gaming Plus, which we ordered. Installation was successful, but the GPU still displayed error codes or RAM issues. Research revealed some MSI boards aren’t compatible with Gigabyte GPUs. We returned the motherboard and purchased the new one. After inserting it, the system remained unresponsive. Fortunately, I had a small PC buzzer on my desk. Connecting it briefly produced a "long" (indicating POST OK) followed by three short beeps—nothing further. Gigabyte indicated RAM was the problem, but testing in another working machine suggested possible GPU concerns. I then used an old Gigabyte GT 630 and installed it. The result was promising: the PCIe slot worked in Gen3 mode after updating BIOS. However, the Gigabyte 3070Ti still didn’t boot. Further troubleshooting pointed to a potential power supply issue, though my colleague dismissed that possibility given the machines’ age. Ultimately, the seller refused a return because the PC was over three months old.
The chance that one GPU is Doa is low, yet two GPUs being Doa is zero (apologies if I misunderstood your point). I think there might be an error in what you said. "The 5600X couldn't recognize the known good GPU from the second PC, so we opted for a 5700X" doesn’t make sense. Are your motherboards’ BIOS updated? Edited October 23, 2023 by leclod
The KFA2 GPU is the original model we purchased 3 to 4 years ago. It got bent quite a bit because these PCs are moved often. I didn’t mention that a colleague accidentally dropped the 5600X during PC assembly a few years back, when I wasn’t present. That unit had bent pins, so we sent it in for replacement. The seller tried to straighten the pins, and it worked—until sometimes it wouldn’t even upload with an older GPU we had on hand. The old board still has the latest firmware, while the new Gigabyte refuses any BIOS files I provide, claiming they’re invalid. I’ve double-checked multiple times; if the file is correct, it should work. It seems the system expects a specific filename, but gigabyte.bin isn’t recognized as valid. @IkeaGnome If the Gigabyte RTX 3070Ti develops bends or cracks, I can inspect it at the office within a few hours.
The card appears to be in good condition with no visible bends or cracks.
Update on the PC: The system functions properly now. Initially, the issue stemmed from the GPU, which required a return and replacement due to faulty VRAM chips. After resolving that, we purchased an ASUS TUF 3070ti for immediate use during online events. The shop refunded the Gigabyte card, so we assumed it wouldn’t be reissued. About a week later, once the PC was ready for streaming, the card arrived and everything worked perfectly. Occasionally, strange BSODs appeared, likely due to the installation being messy. We plan to reinstall it in the new year. Thank you all for your assistance—Merry Christmas and a happy new year!
