The magic of Binning

At CES, TweakTown was given a giveaway, an engineering sample of Patriot’s Viper Xtreme 5 DDR5. This isn’t your average retail kit, but it has selected Hynix ICs and is meant to show what Patriot’s DDR5 line can do when everything goes right. When added to their test machine, the DIMMs were identified as 8000 MHz with CAS38-48-48-84 2T, operating at 1.45 V. Since these DIMMs should offer more than your average retail kit, they spent quite time by trying different overclocking settings.

At stock settings, this Viper Xtreme 5 was quite impressive and occasionally outperformed a DDR5-8200 kit and definitely beat other DDR5-8000 kits with a few odd exceptions. After adding a massive Pure Wings 2 RAM fan from be quiet! they proceeded to push this kit to its limits. While they managed to tighten up the timings while keeping DDR5-8000, what really impressed them was a completely stable DDR5-8800 with slightly relaxed 40-52-52-131-183 2T timings.
