    Ryzen 5900X overclocking help

    EDC runs at 100% no matter what (from my observations). I'm yet to see someone who isn't hitting 100% EDC. It might lower the temps very slightly because at stock settings you will hit PPT or TDC limits quickly.

    Ryzen 5900X overclocking help

    It doesn't do any of that. it just allows all core boost to go higher before hitting limits. Only thing that limits power usage and temps are PPT and to some extent TDC.

    Ryzen 5900X overclocking help

    Correct. If you keep getting this error during idle, then you need to keep lowering the CO undervolt for that core. So if -15 wasn't stable, -10 is the next thing to try and so on. Some people can only do -5 on their preferred cores, some couldn't move off of 0, and some people claimed to have...

    Ryzen 5900X overclocking help

    Yes, sort of. In the event viewer, you will see the APIC ID number. That ties into a physical core of the CPU. The physical cores start at 0 and so do the APIC IDs. The formula is FLOOR(APICID/2). So you are looking at something like: Core 0 - APIC IDs 0 and 1, Core 1 - APIC IDs 2 and 3, Core...

If I was doing it over, I would probably look for a 3600c16 kit, as it seems to do 3800c14 more often. I could only...

    Ryzen 5900X overclocking help

    It's the norm for b-die. Check out the community spreadsheets for Zen2 and Zen3. 9 out of 10 people run that. :) It's a $200 kit in a $3k PC. If it dies, it dies. Probably won't happen for years.

    Ryzen 5900X overclocking help

    Right. Any other RAM it's too much. For b-die, people run that 24/7. Some go up to 1.6v. I have active cooling on my RAM, and it doesn't go above 40c under load and above 45c under load while gaming. G.Skill sells b-die kits rated for 1.5v with long-term (lifetime) warranty...

    Ryzen 5900X overclocking help

    Makes sense. I am only pushing the RAM really. The CPU is actually undervolted and the 3080 is at stock volts but boosted curve. The RAM at 1.49v is the only scary part, but everyone says b-die can take it long-term. We'll see.

    Ryzen 5900X overclocking help

    I have a note in there about L3 cache speeds. We are supposed to be seeing around 1200MB on 5900x, since they have 2 CCDs. However, even at stock everyone with PB sees between 600 to 700. Once you start using PBO, in my case specifically, the higher I went on TDC limit and the lower I went on...

    Ryzen 5900X overclocking help

    Bumped my RAM OC up to 3733 c14-13-13-13-27-40-T1 (GDM Enabled) at 1.5v. Scores went up. Latency is down to 55.5ns in AIDA64. Makes a big difference in how snappy everything feels. Windows seem to open before my mouse button comes back up. :D

    Ryzen 5900X overclocking help

    Something doesn't seem right. If I were you, I would try clearing the CMOS. Then loading optimized defaults. Then checking things out. And then slowly try your settings again. CPU overclock first. Then RAM overclock. Personally, I am not considering 11900K. It sucks you are having so much...

    HWInfo64 shows it or OCCT shows it as well, as it used HWInfo engine behind the scenes.

    99% done tweaking: https://www.reddit.com/r/overclocking/comments/kmryeg/my_5900x_final_oc/ All core boosts to 4.8GHz now effective (temp limited). Single core boosts to 5GHz.

    Odd. Mine behaves the same as what Endgame described. Negative CO values result in higher All Core boosts.

    Why do you think this is the case? I've seen similar comments on reddit and people said this is not true. Also, the description clearly states this is not the case. I'd be careful assuming this without some really good proof.

    Check your BIOS for "Gear Down Mode" setting. If that is enabled, that is why your CL would run at 18. And no, the sensors are the same but the software is not always accurate. HWInfo is the correct software to use for temps...or Ryzen Master.

    Ryzen 5900X overclocking help

    Voltage by itself doesn't matter. It's voltage plus current (+ temps) that matters. Up to 1.5v under low current (so low load) is perfectly fine. High current (such as all core load) is where you shouldn't be running above your FIT voltage. This seems to be in the 1.2xx range for 5900x (although...

    My settings are here: https://www.reddit.com/r/overclocking/comments/kmryeg/my_5900x_final_oc/ My scores are not the absolute highest, but that is because I am not using the PBO2 clock boost. If I was able to do +200 like many can, I would have very similar scores. For my CPU, +200 wasn't...

    Ryzen 5900X overclocking help

    You are doing it wrong. (so did I, until I figured things out). I'll post more details in a few hours, have to leave now. In a nutshell, less voltage = more boosts for MC and SC under PBO2. So you need to drop the voltage using Curve Optimizer specifically, but also potentially using negative...

    Official NVIDIA Ampere In-Stock Thread

    I scored both a 5900x and a 3080 with Newegg combos, one with a motherboard and one with a PSU. Was able to return both the MB and the PSU with no restocking fee, just had to pay for return shipping. Newegg needs to stop with all this combo BS if they don't want returns. Forcing crappy Gigabyte...

    Got the Gigabyte Vision OC 3080 from Newegg yesterday. No bots or anything, just F5. Thank you for the heads up. Really helped knowing the time. Not sure how this thing is going to look in my build, since I am not doing an all white build. :p
