  1. What is your definition of "micro stuttering"?
  2. Try both the motherboard HDMI port and GPU card's HDMI port. See if any has signal.
  3. I have a Vegeance i7400. On the default BIOS setting, fans are controlled by CPU temperature or "System" temperature. You can enter the BIOS menu and set them to your preference. I set mine up to enable the front 3 fans controlled by CPU temp and the rear fan controlled by System temp. It works well for my applications (software development).
  4. I also had a similar issue. On my first i7400, it had BSOD after it did the Windows update. Corsair support couldn't resolve the issue and so I sent it back. The 2nd i7400 also had the same issue. Instead of contacting their support again, I re-installed the Windows 11 using an external USB stick. It has been working well since then (about 3 months ago). Now I really like this machine!
  5. Thanks for all the pointers in the past. The coolant temp does not go above low 40s. But I pushed back PL1=230W. The performance difference is very small among 230w, 240w, and 250w. With a 10 minute thermal stress run, the Cinebench R23 MC score is 37K. I also use various tools to stress test and found it stable. A key from my experience is to under volt the CPU. With MSI board, CPU Lite Load seems to work well.
  6. After some tweaking, I get R23 multi-core > 38000. I set PL1=PL2=253w. It is thermal stable for 30 minutes of stress test; i.e. no thermal throttling on HWInfo64.
  7. Update on my Cinebench 2024 GPU test score: I disabled the ECC on the 4090 GPU card. Its GPU score is now normal and around 35,000. Good GPU!!
  8. I have an i7400 with Intel i9-13900K and Nvidia 4090. After 3 months of tweaking and updating, my quick summary is that it is a computer that works for me. But if I wanted to maximize Intel i9-13900K, I would go with i8100. Thankfully for me, the power/heat dissipation improvement from i8100 is not needed for my practical uses. I am not a gamer. In fact, I don't have any games on my PC. I am a professional AI software developer and an amateur photographer. So I want a computer that is quiet when I am researching a topic online, has a burst power for photo export, and very powerful/stable for AI model training (50-60% CPU, 90+% GPU, and runs for a day or two). So this i7400 fits my needs very well. The obvious downside of i7400 is the small-ish 240mm water cooler. I had to dial down the long-term CPU power limit (PL1) to 180 watts to prevent thermal throttling on the CPU cores. For anyone who needs the 253 watts of rated power for 13900K, this is probably not the right choice. I want to thank Marcy at Corsair customer services/tech support. I have had a wonderful experience working with Marcy to get my questions answered.
  9. I received mine in July 2023. It came with ASUS TUF 4090. I did a quick Cinebench 2024 GPU 1 pass benchmark. The score is about 10% lower than average.
  10. Thank you. Problem for this "other device" solved! I already have the Intel Driver & Support Assistant. But it did not find any update, after I removed "base system device". However, Corsair website has a driver for it. I downloaded it and it fixed the problem.
  11. Thanks for the link to Cinebench 2024. I used it to benchmark my i7400 and found the scores are about 10% lowered than the average scores of these devices. It is probably not worth the effort to tweak them to get 10% gain for my uses (software development). The scores from my i7400 are: 4090: 31,630 Single core: 125 Multi core: 1910
  12. Thanks. PCIlookup website couldn't figure out what it is.
  13. My smartphone is already connected to this i7400 via Phone Link. But these "other devices" still show them as unknown.
  14. Well, I spoke too soon. After checked "show hidden devices", it displays the following:
