Max Trefi can go up to 262k, but there is no noticeable benefit from going higher than 65535, and a lot of risk of increasing stability problems with high heat. CAS latency seems to have a lesser effect on latency on DDR5 than 4, for example. There are two channels per dimm and two memory controllers on the DDR5 side so the dims operate in quad channel mode for 2 sticks. DDR4 and DDR5 memory should no longer be compared on an apples to apples level due to the number of changes. The new changes to the bank structure means that two sticks of DDR5 are operating in the equivalent of "Quad channel" mode when compared to DDR4. Power management (PMIC) has also been moved from the motherboard to the memory, so the memory itself manages the voltages. The AVX512 offsets and clipping are available just like they were and described in the Rocket Lake Z590 guide.ĭDR5 operates in 2x32 bit mode rather than 1圆4 bit mode. To use AVX-512, please disable all of the E-cores. I encountered OCP with AVX512 at 5.2 ghz, so if you encounter it, you can change CPU Current Capacity in Digi+VRM. While QS samples tend to reflect final retail hardware, there may still be undocumented differences, errata, thermal issues or features that may be present or not present on retail parts.ĪVX-512 support is available with Asus boards! Some of you may really love this but I am not sure if AVX512 was intended or QA'd by Intel, VRM limits may not be set for high OCP limits with AVX512. Identically, or even not work at all on retail CPU's. Pre-production boards, so it is possible that some features may perform differently, slightly differently Without their help, I would never have been able to do this.Īnd VERY BIG thank you to Skatterbencher for his excellent, precise, clear cut youtube videos on explaining these features and helping me with this guide.ĭisclaimer ! These settings and methods were tested on *ENGINEERING* Qualification Sample CPU's ("QS") and #Disable clocks in stockfish chess gui series#Asus Z690, Maximus series and Alder Lake: The best tools for the best FPS.įirst, let me start by thanking Shamino ROG Asus for allowing me and the other testers to put this exciting new hardware through its paces and experiment with the new overclocking features and architecture changes, and for the hard work to get these boards running well with these new features.Īlso I need to thank cstkl1 and RobertoSampiao for helping me write this.
