AMD's EPYC 4124P "Zen 4" CPU is an entry-level quad-core chip that has been overclocked to 6.6 GHz using B650 motherboards motherboards.
Overclocker achieves the best 4-core 7-Zip score with AMD's most entry-level EPYC 4124P "Zen 4" CPU on a B650 motherboard
AMD EPYC 4004 CPUs launched in May this year are aimed at entry-level servers & workstations compatible with the AM5 socket. The best thing about these processors is that many motherboard makers support them on some of their B650 chipset motherboards. Even though not every board maker has listed the support for EPYC 4004 processors, the latest results show that users can install these on a regular B650 chipset motherboard and even overclock them to the extreme.
AMD EPYC's most entry-level SKU, EPYC 4124P CPU, was recently benchmarked on 7-Zip by the prominent overclocker Sergamann. The HWBOT results show that not only the user was able to get it working properly on the Gigabyte B650E AORUS Tachyon but he also broke the quad-core world records in clock speed & 7-Zip score.
Sergamann used liquid nitrogen cooling to achieve 6,664.75 MHz of clock speed on the EPYC 4124P, which is inherently a locked chip. The workaround for the overclock not only worked to increase its boost clock on all cores from 5.1 GHz to 6.6 GHz, but it also resulted in a good 82943 MIPS score, which is the highest by any 4-core processor. Some other users also reached over 6.0 GHz but on a much inferior motherboard.
So when an OC friend of mine said hey did you know they make a quad core AM5 cpu and it's Epyc I knew I had to give it a shot. Enter the AMD EPYC 4124P. Will it be unlocked, well it's a "server named" part so probably not. Ok well we have bclk we can overclock with. Will it even boot or be recognized in a "normal" AM5 socket motherboard without ECC memory etc? Alot of questions but worth the risk if it pans out. These seem quite rare in the USA. I had to snag mine off ebay from Italy.
Fast forward 12 days and it's here and guess what? It drops right in, is fully unlocked and overclocks like hell! AMD give the people what they want the quad of the gods! 5.5ghz is possible 1.35v on water cooling for threaded benchmarks. 6.4ghz+ is possible on ln2 and it destroys the 4 core rankings at HWBot.org that is all for now. Keep some secrets for later.
Overclocker OBSCUREPARADOX was able to achieve a 6,591.57 MHz on an ASRock B650M-HDV/M.2 motherboard and overclocker SPLAVE also reached nearly 6.5 GHz on the same motherboard. All these scores are pretty recent(mostly 1-2 days old) and reveal that most B650 motherboards can support the EPYC 4004 processors out of the box. And interestingly enough, you don't even need to go the high-end Tachyon route as entry-level products such as the ASRock B650M can achieve stellar results.
Indeed, some motherboard vendors like ASUS have listed the support for select AMD EPYC 4004 processors on some B650 chipset boards but none of the EPYC 4004 processors were listed in the CPU support list of B650E AORUS Tachyon and B650M-HDV/M.2. the CPUs may be added to their support list soon but even without the mention, we can see that EPYC 4004 can be used for building entry-level workstations.
With the AMD B650 chipset motherboards, you do miss out on some additional features, including the support for ECC memory but due to offering overclocking support, users can find a workaround to overclock the EPYC 4004 processors as seen with these results.
