13900KS, XTU yes or no?

[TheGoodDave]

I have a 13900KS, Gigabyte Z790 Aorus Master, Arctic LF2 420mm AIO, and I've installed the Thermal Grizzly contact frame, and I'm using Kingpin KPx thermal paste.

I have the BIOS set to enforce all Intel power limits wherever possible and have disabled all BIOS overclocking features.

Intel's spec page for the 13900KS lists 253W TDP and 400A iccMax as defaults. In XTU, when stress testing with these limits enforced, I am power- and current-throttled, but temps hover around 75'C. Though, when turning on automatic OC, it suggests a 330W TDP and 450A iccMax, and when stress testing with its automatic settings I don't experience power- or current-throttling, and temperatures hover around 85'C. TDP hovers around 290W.

Should I go with the XTU automatic OC settings? Is it safe in regards to all of the degradation issues that have come to light this year? Or should I just keep it at stock limits and play it safe?

I do video rendering with some regularity, so I hit the CPU with 100% utilization for a few hours a week.

Thanks!

Intel's safety guidelines are that iccMax should not exceed 400 A. With my 13900KS on the ASUS ROG Z790 Apex Encore I have had a mild multicore regression compared to previous microcodes on my old MSI Z690 Ace motherboard. It's down by about 2000 points on R23 overall - though P-core scores are the same.

Since you are doing constant high-current workload with video rendering and encoding, I suggest you abide by Intel's current guidelines if you want your chip to last.

So do you recommend keeping the OC but dropping the iccMax back down to 400A, or ditching the OC altogether?

Ditch it, imo. Video rendering and encoding are AVX-heavy workloads and these push a lot current through the CPU. A small undervolt might benefit you more than a clock target that the chip won't reach under these workloads unless it's on chilled water anyway.

If it dies just RMA it

Hehe true but since OP is making money with the PC I reckon he doesn't wanna deal with RMA downtime, better play it safe

I appreciate the generous assumption that my tiny YouTube channel is making money, lol

Anyway, thanks! Yeah, I'll just ditch the OC.
