News AMD EPYC CPU hacked onto B650 motherboard, hits 6.6 GHz with liquid nitrogen — $159 EPYC 4124P shows immense overclocking potential

The article said:
many consider these chips a rebrand of the mainstream Ryzen 7000 chips with enterprise features, such as support for ECC memory.
Regular, non-APU Ryzens (i.e. not the 8000-series, if we're talking about AM5 processors) also support ECC - just not officially. Some motherboard vendors (e.g. ASRock Rack; I think also Supermicro?) will do the qualification and make the guarantees for those CPUs that AMD won't.
 
There is nothing new about B650 boards supporting EPYC 4004 series, Asus have done it for a good while now with my TUF Gaming B650M WiFi board as evidenced here.
But afaik that series of chips have locked multipliers so unless you can get away with BLCK overclocking they will be boring to over clockers. :sunglasses:
 
I personally consider the headline a bit disingenuous when the chip is really a straight up consumer Ryzen chip that uses AM5. Real Epycs do similar stuff on LN2. Why not just show them?
You're right, although there is no comparable DIY quad-core on AM5. It might even be based on an APU die, like an 8300G? I have no clue.

The screenshot on HWBOT shows it's a multiplier overclock, BCLK is still 100MHz. so there is some sort of BIOS hack being used to enable the overclocking on the EPYC.

A 30% overclock on LN2 isn't that impressive, I've seen that happen with air cooling. The 74% from the base clock is much more of a thing. But then, it does half of that on it's own.

The interesting part is overclocking server parts on a consumer board. Also not the first time, but it's rare enough to give it some attention.

It’s not actually server parts. It’s a consumer Ryzen chip with official ECC support and enterprise security measures . It doesn’t even get any extra PCIE lanes or anything.
