MSI Z690 Tomahawk vs Gigabyte Z790 Gaming X AX for 13600kf

[jaszy]

I maxed out at 7800 on the Z690 Tachyon. 8000 is bootable though.

1DPC board though

It's just generally odd that the 2DPC examples I gave have more headroom regardless of having identical trace layouts/EE design.

Your saying between Z690 and Z790 the layout is identical, but the speeds are different?

I would argue probably more than meets the eye here. I would like to see X-rays of both and full part breakdown before I commit to believing the limitation is self imposed by the vendors.

I would argue it has to do with DMI/SB limitations, even though it really shouldn't impact it.

The Z690/Z790 HERO boards are prob the best example since theres no shielding on them... front and back. They're literally identical trace designs.

thanks everybody for replying. I got the GB z790 and the 6000 kit.
What do you guys think of these numbers during a CB R23 run at default GB Bios settings?
It seems an Arctic 34 eSports is not enough.

You have 3c headroom . Intel CPUs now are designed to turbo until 100c or reach the turbo freq. Whatever comes first.

lol. actually lost those 3C when it completed a 10min run.
What about voltages, do they all look as expected to you?

Looks fine. 1.2 - 1.275v is normal for vcore. Its interesting you have your power limit set to infinity (4096w). Spec sheet for that cooler isn't listed but I assume it's 150w. Lowering your TDP on the motherboard might yield better performance.

apart from enabling xmp, default GB bios (Ver.F6) out of the box.

Lowering your TDP on the motherboard might yield better performance.

is this by setting turbo power limits PL1 and PL2 in bios? what values?

I don't think it really matters on 13600k.

Power limits don't really increase TDP due to core config (6+8) via MT testing.

13W difference wont really do anything in regards to the cooler, though power limits could impact overall EMI from VRM/CPU. I believe this is part of the reason why SSC is default on modern intel chips.

Intel Core i5-13600K Review - Best Gaming CPU

Core i5-13600K is a gamer's dream! The new processor achieves gaming numbers that match the best AMD Zen 4 offerings, at a much more competitive $320 price point. Our review also shows that 13600K can shine in applications, beating the much higher positioned Core i7-12700K.

Single sample obviously. Could be ~10W variance on a chip per chip basis.

True it might not make a difference. Drawing 170w for a cooler rated for 150~.
