Since you are talking about OC and the 12400F is a locked multiplier CPU I take it the ASRock B760M Riptide has BCLK overclocking. I built a 12400F/B760/RTX 4060 system for a family member and she is very pleased with it. It was an ASUS board that pushed the 12400F to 4.4GHz all core by applying unlimited current and effectively unlimited power settings with multicore enhancement. No issues with a CPU of this power level.

It's by far the cheapest board with BCLK overclocking at $130 (it was $100 for a while). It overclocks RAM decently well, and the VRM is serviceable, even though it uses cheap discrete MOSFETs. The older motherboards with clockgens were priced so high, it defeated the purpose of buying a low-end CPU to overclock.

The very thing lots of people complained about so that Asus was forced to amend the Bios to restrict the current limits strictly to those specified by Intel.
I'd avoid Assus and stick with the Asrock.

What we are talking about here is extracting more performance from a 12400F. The method used by ASUS was also used by Gigabyte, MSI and even ASRock. The issue was that originally it was a set of optional settings, Intel base settings were the default. Then the optional performance settings became the default. But this does not cause issues with a processor like this.

Where the ASRock Riptide is unique is that it allows BCLK overclocking. Normally B760 boards are locked to 100MHz BCLK. TechPowerUp when testing the i5 12600 in a suitable board were able to achieve 125MHz. So with a Riptide something like that or better might be possible. Intel blocked BCLK overclocking in some of the boards that allowed it with a BIOS update and blocked it in 13th/14th gen processors with a microcode update. So the Riptide only works with 12th gen and maybe only with its original BIOS. But as a way of boosting 12400F performance at this price point it's the only game in town.

A quirk that should be noted with BLCK OC of non-K CPUs is that in order to work the Mobo is pushing a very old CPU microcode(with the OC bug) that does not support some low power states and as a result you cannot use the Sleep function in Windows if the OC function is enabled. When the OC function is disabled the Sleep option "magically" appears in Windows.

That's just impossible with a locked Intel CPU....

You are wrong.

The 12400/F can be pushed to 5 GHz+ with ECLK OC, quite easily.

Yields roughly +30% or a bit more performance, making it on par with the 7600X/7700, at approximately half the platform cost.

It can be necessary to run faster RAM to keep the CPU fed, however.

Definitely go for the 4070.

I would also suggest these three parts as replacements.

1 TB M.2 is hardly worth the slot these days, fills up quickly.

You are wrong.

Sorry I meant ALL CORE.

 

[dgianstefani]

Sorry I meant ALL CORE.

Still wrong I'm afraid. ECLK allows all core OC, easily, to 5.0 GHz for a Alder lake locked CPU.

Good samples can do 5.2 GHz or sometimes higher.

Brings power draw from 70 W to around 120-140 W under full synthetic load, but it's not signficant or hard to cool.

Ok, never seen that before with a locked intel CPU, it was always one core with the highest turbo bin and in the past there was no way to get an ALL CORE highest turbo bin speed on a locked CPU...
Even when overclocking, only one core would have the highest clock, at least it has always been like that.

Otherwise there would be no point if intel would sell real unlocked multiplier CPU's.

Never seen that you can synchronise all cores with a locked intel CPU.

 

[ShrekOC]

This is all BCLK. In fact you want to limit the multiplier to 40x. If you run the BCLK at 130, the single core turbo will default to 5.72GHz with a multipler of 44 which I doubt it can handle.
