Desktop Xeon Sapphire Rapids showed great overclocking potential up

Desktop Xeon Sapphire Rapids showed great overclocking potential – up to 5.3 GHz with liquid cooling

Earlier this month, Intel released its top-performing desktop processors, the Xeon W-3400 and Xeon W-2400 workstation chips from the Sapphire Rapids family. Some of the new products have an unlocked multiplier, which means they support manual overclocking. Enthusiasts are already experimenting with new products with might and main, thanks to which we can explore the overclocking potential of new products.

Another set of records in the HWBot database was achieved by a well-known enthusiast using the alias Splave – with the help of overclocked 24-core Xeon w7-2495X processor He immediately set 14 world records for 24-core processors and 18 records for this processor model. Enthusiast used motherboard ASRock W790WS and 64GB of DDR5 RAM overclocked to an effective frequency of 6800MHz. Most importantly, the processor worked with a custom liquid cooling system in the experiments.

In most tests, the LSS overclocked Xeon w7-2495X ran at 5.1 GHz. However, with some loads it was possible to maintain stability only at 4.5-4.7 GHz, while in other experiments it was possible to achieve even higher frequencies – the maximum was 5.3 GHz. Remember that the base frequency of the Xeon w7-2495X is 2.5 GHz and the maximum turbo frequency for a single core is 4.8 GHz. That means the chip doubled its base frequency in most tests. At the same time, in some tests the temperature did not rise above 60 ° C, but in others it rose above 70 ° C, and in one even 91 ° C.

On the other hand, an enthusiast with the alias Safedisk experimented with overclocking the same Xeon w7-2495X, but with the help of extreme liquid nitrogen cooling. He managed to achieve stable operation with a frequency of up to 5.85 GHz, although in most tests the frequency was 5.75 GHz, and in one it remained stable only at 5.34 GHz.

Other representatives of the Xeon Sapphire Rapids desktop family could also be noted in the HWBot database. So, the flagship processor Xeon w9-3495X with 56 cores and a base frequency of 1.9 GHz was able to work stably at a frequency of up to 5.46 GHz, but this required cooling with liquid nitrogen. “Under water” could not even overcome 4 GHz in most tests. The Xeon w9-3475X model with 36 cores (2.2 GHz) was overclocked to 5.7 GHz with nitrogen. On the other hand, there is only one record for overclocking the 12-core Xeon w5-2455X (3.2 GHz) – under liquid nitrogen it was only overclocked to 5.14 GHz, which is clearly not the limit.

In general, despite the abundance of cores, the Xeon W-3400 and Xeon W-2400 processors have a very, very impressive overclocking potential. Even without extreme cooling with new chips, you can achieve a very clear frequency increase relative to the base level.
