@starcoaster @jstudrawa Success! 5Ghz style points achieved. Currently stable at 1.32V, I haven't tried lowering it yet, but at least I know it can do 5Ghz.

Is your RAM set to 3000Mhz in BIOS? By default every motherboard will set it to 2133 which is considerable bottleneck for Ryzen CPU. EDIT: Also make sure RAM is running in dual channel. Sticks should be installed in slot 2 and 4 on the board.

Welcome. There is "Troubleshooting" subsection for when you need to solve a problem.

I'm currently at 4.8 1.32V. Temps are 80c under Cinebench. Score 1497. Will do more stress testing before going higher. Although HWMonitor reports 1.27v during tests, so there is that.

So, at default settings, I get 4.7 turbo on all cores in Cinebench. Temps rise to low/mid 70s, voltage to around 1.325v. Score 1440. I will try 4.8 at 1.32 and see what happens.

So I've finally ordered a cooler (Dark Rock Pro 4) that should arrive today. I wanted to get some final preparation info before going into overclocking. As far as I know, I can set x47 multiplier without touching the voltage. But I'd like to know what voltages I should expect to use for higher 4.8-5Ghz(if possible) overclock. CPU isn't delided, so temps would probably still be high even under high end cooler. But they shouldn't be too bad.

I begin to suspect that your motherboard is unable to sustain stable high overclock on such high end CPU.

LLC - Line Load Calibration. This setting adjusts for voltage drops that occur when CPU hits high load.

Forget XTU. Uninstall it, burn it with fire and throw off a bridge. In BIOS, set 1.32V Core voltage, x50 core ration, LLC in mid or one level below middle ground and ACX -2. Get HWMonitor and Prime95 or AIDA64 or even Cinebench for stress test. If test crashes your system, up the voltage by 0.01V increments.

Because Bios settings weren't changed, so its reporting default values. XTU will apply its overclock when you start your PC.

You have to set manual voltage/LLC and Core Ratio multiplier in Bios. I don't trust outside software to control any overclocking settings. If you don't want to do that, try setting CPU core voltage in XTU if possible. No offsets, no Autos, just enter a number and test it. In your case, you should set it to around 1.32v to have CPU stable.

Why don't you use motherboard Bios for overclocking? Anyway, try leaving Negative AVX at 0 and see if you still get drops.

Do you have proper settings for maintaining stable overclock? Set voltage, LLC, core multiplier set to x50? Whats your AVX offset?

In what game are you getting those drops?

What voltage do you get during tests? Try lowering LLC, it might be pushing your voltage above and beyond 1.24V, hence the temperature spike.

Your issue was positive pressure. You can have x2 140mm fans at the front, and x2 or x3 120mm exhaust fans at the back and top. If you get x2 120mm fans as exhaust, they have to run at higher RPM than 140mm fans to keep optimal pressure. As @Firewrath9 suggested, you can get Silent Wing 3 fans, they're high quality fans. I have 5 of them running in my system (x2 140mm intakes, and x3 120mm exhausts), they're nice and quiet even under load. It produces around 25db at idle, and 40-45db under heavy load.

Do you have your RAM set to 3000Mhz in bios? By default, all RAM runs at 2133Mhz which is a big bottleneck for Ryzen CPU.

You should be able to push metal connector from the plastic housing, secure loose cable in it, and push it back together. As an emergency option, you can use reset switch instead of power switch to turn your PC on.

PSU wattage?

Single/Dual channel?

Possible issue, and maybe RAM, I don't know your setup. I've ran BF5 on 8600k overclocked to 5Ghz, and I was still getting horrible frame times above 100FPS. CPU was always above 90% load while GPU (RTX2080) was dipping below 80% usage. Then I upgraded to 8700k, and vuala, even at stock speed perfectly stable FPS with no stutters or frame drops. I spend a lot of time on BF forums. Many people with i5s report issues with stuttering and frame time drops even during BF1 days. That engine is just very taxing because of AVX workload that it puts onto the CPU.

Have you set the speed to 2666Mhz in the Bios?

Single channel of slow DDR4 RAM. There is your problem.

Makes non sense. How memory overclocking can kill the CPU.

For me Without headphone - over 30db is getting a little loud. With headphone - I do not care.
