Hi, as the title, do you guys still overclock? For 24/7 usage not just for benchmarking i have a 13900k on a strix z790e and gskill ddr5 6400cl32 Cooler is arctic freezer ii 360 Bios says sp97 and i was wondering if its worth looking to overclocking still for 24/7 use
I have A.I. overclocking enabled in my BIOS with XMP II selected. I've OC'd my 4090 to 3ghz on the core and 11,300 to 11,500 on the memory. I've witnessed 5 to 15 fps increase in some titles. I just finished testing my OC profile in Cyberpunk and witnessed a 7 to 11 fps increase. I have 10 Lian Li fans and a water cooled CPU. My intel build is practically the same as yours. I messed around with the overclocks just to see the difference in framerate. Our default clocks gives us fantastic performance. If my framerate in most games is well over 100fps @4K max settings, the extra frames aren't noticed very much in my opinion. I've decided to shutdown the overclocks due to having outstanding performance without them.

Great! Thanks! I might add another 2x32Gb to fill the 4 slots for aesthetics just that from experience in my previous rig, going from 32 to 64 didnt do anything for me performance wise
It does look nice seeing all 4 slots filled though. but any issues with the memory controller with populating all 4 sticks?
No not at all. On the Intel side of things the BIOS accepts compatible memory nicely. Configures with ease. The only complaint I have about the Z790 motherboards are the Ethernet controllers. The 1226-V is garbage. I purchased an adapter and my download speeds are top notch now. I hope you have a good revision and don't run into problems.
No experience with the 13900k but if DDR4 is anything to go by, the greatest gains in gaming experience are to be found from improving RAM timings. It might not result in much or any average fps increase but frametime consistency and 1% lows can be massively improved.
Some first results from my 13900KF. It goes quite easily to 6.2GHz even with basic ASUS AI OC, but I prefer power consumption, so I did a very basic undervolt, it does 5.5GHz@1.3V and probably could go even lower, but I need some voltage headroom of confidence. Anyway, with power limit of 150W it (almost) reaches stock 13900K in multithreading and is even faster in single thread, so I'm quite happy with this new setup. btw. the ASUS reports SP109. Maximum temperatures during stress testing are around 60-65C:
I'm running almost stock cpu, but 8400c34 max tweaked memory. This for the best gaming performance Using Asus Apex and watercooled Hynix A-die.
@nizzen 1.67V(!) on DDR5 modules... that is insane. My DDR5 6800Mhz CL32 are running with 1.425V. I wouldn't push more than 1.5V to them.
My (probably final) undervolt for 150W power limit: 5.8GHz boost / 5.6GHz all core @ 1.27V+- / 4.3GHz ecores / DDR5 6800CL32 1.42V And it's really fast... I'm having hard time making my games CPU limited even if I try really hard with very low resolutions. So honestly there is really no point in OCing these CPUs.
The smarter way of using a 13900K is to undervolt and afterwards (!) you can try to add 100 MHz on a few cores. My current undervolted 13900K OC: 58/59/55/55/56/56/55/55//43/43/45/44. No efficiency loss for these slight overclocks (power increase ~ performance increase). About 253 W for 40k+ scores in CB23 (lower is possible, but not Folding@home stable). I use a rather complex combination of LLC + AC LL + offset + TVB voltage + Core PLL offset, but even with a simple undervolt you can run stock clocks at considerably lower power draw, temps and thus noise. The most important part is to use a power-limit, so that you optimize voltages/stability for realworld applications instead of optimizing for Prime95 at a unlimited power.
