It’s just been a day that AMD has launched its Zen 2 based Renoir APUs and the Ryzen PRO 4000 desktop processors, now there’s a leak that shows some insane memory overclock with the new 8-core AMD Ryzen PRO 7 4750G. We previously have seen these Renoir APUs get overclocked on the new B550 motherboards so getting this level is very much expected.
Higher clock speeds and higher RAM frequency will obviously help these Renoir APUs perform well both on the CPU and GPU front. The Taiwanese overclockers, TSAIK and Bianbao, have pushed the new Ryzen PRO 7 4750G to insane speeds both on the processor and memory front with LN2 overclocking on ASUS’s and MSI’s B550 motherboards.
The new AMD Ryzen 7 PRO 4750G is almost the same as the other flagship Renoir desktop APU 8-core and 16 thread. It comes with 4 MB of L2 and 8 MB of L3 cache for a total of 12 MB cache. The APU features a base clock speed of 3.60 GHz and a boost clock speed of 4.45 GHz. The APU operates with a 65W TDP and for integrated graphics, there’s the 7nm Vega GPU which comes with 8 CUs to form 512 cores and clocked at 2100 MHz.
The first result came in the form of CPU overclock which has been achieved by TSAIK. The APU was overclocked to a massive 5.8 GHz (5812.9 MHz) on an MSI MPG B550 Gaming Carbon motherboard. This represents almost 61.47% boost over the base frequency of the chip and it can only be achieved with the use of liquid nitrogen cooling.
The second overclock came through Bianbao who has set another record of the fastest memory overclocking speed on the AMD AM4 platform. So, the AMD Ryzen 7 PRO 4750G was used in the test with LN2 cooling and it CPU was clocked down to just 2.5 GHz at 1.232V, however, the memory was pushed to unimaginable DDR4-6234 MHz clock speed (3117.40 MHz).
The timings of the RAM were configured to 24-27-27-58-127-1T, the DIMMs used are the Crucial Ballistix DDR4-2666 (8 GB x 2) kit. This record memory overclock was possible on an ASUS ROG STRIX B550-I Gaming motherboard. Seeing such insane overclock speeds and experiments, these new Ryzen 4000 APUs is quite promising and the B550 motherboards will be a good option for most overclock enthusiasts out there, no doubts.
