There is no need to change memory frequency. 900 VDDG (both voltages) and confirm its stable and slowly start raising FCLK. That last part is important because I have extensively tested and it seems TOO MUCH SOC voltage, like the 1.1 volts MSI likes to apply stock makes everything below 1800 FCLK spit WHEA errors.ġ600 FCLK 1 volt SOC =Stable 1.1 volt SOC = Tons of WHEA errorsġ900 FCLK 1 volt SOC = WHEA errors 1.1 volt SOC= WHEA errors 1.15 Volt SOC= Stable 900 VDDG 1600 FCLK only raising SOC voltage when I hit WHEA errors as I raised FCLK. "I was able to get 1933 FCLK stable by starting at 1 volt SOC and. I think Zen 3 is just super sensitive to SOC voltage.
I was getting the same spaz outs above 3200 that has been widely reported. Zen TLB consists of dedicated level one TLB for instruction cache and another one for data cache.B550 tomahawk owner here.
ECC: x4 DRAM device failure correction (Chipkill), x8 SEC-DED ECC, Patrol and Demand scrubbing, Data poisoning. Naples: up to PC4-21300L (DDR4-2666 RDIMM/LRDIMM), ECC supported. #Zen 3 stock pro
Raven Ridge: up to PC4-23466U (DDR4-2933 UDIMM), ECC supported by PRO models. Summit Ridge: up to PC4-21300U (DDR4-2666 UDIMM), ECC supported. Raven Ridge: 4 MiB/CCX, shared across all cores.

Single/Multi-chip Packages Single-die Ĩ-core configuration: Memory Hierarchy Never use them in production.īlock Diagram Client Configuration Entire SoC Overview This has also been confirmed by Agner here. Note: WikiChip's testing shows FMA4 still works despite not being officially supported and not even reported by CPUID. Note that with Zen, AMD dropped support for XOP, TBM, and LWP. While not new, Zen also supports AVX, AVX2, FMA3, BMI1, BMI2, AES, RdRand, SMEP. CLZERO - Zero-out Cache Line (AMD exclusive). SMAP - Supervisor Mode Access Prevention. ADX - Multi-Precision Add-Carry Instruction extension. Zen introduced a number of new x86 instructions: Write-back L1 cache eviction policy (From write-through). 64 KiB (double from previous capacity of 32 KiB). Faster Load to FPU (down to 7, from 9 cycles). Larger retire throughput (8, up from 4). Better branch predicitons with 2 branches per BTB entry. Simultaneous Multithreading (SMT) support, 2 threads/core (see § Simultaneous MultiThreading for details). Traditional design for cores without shared blocks (e.g. Return to conventional high-performance x86 design. Based on the industry-standardized SPECint_base2006 score compiled with GCC 4.6 -O2 at a fixed 3.4GHz. 52% improvement in IPC per core for a single-thread (AMD Claim). >15% switching capacitance (C AC) improvement. Power focus from design, employs low-power design methodologies. More aggressive clock gating with multi-level regions. 
Cover the entire spectrum from fanless notebooks to high-performance desktops. Zen was designed to succeed both Excavator (High-performance) and Puma (Low-power) covering the entire range in one architecture. 
Mainstream Zen-based microprocessors utilize AMD's Socket AM4 unified platform along with the Promontory chipset.

AOCC is an LLVM port especially modified to generate optimized x86 code for the Zen microarchitecture.ĪMD Zen is an entirely new design from the ground up which introduces considerable amount of improvements and design changes over Excavator. With the release of Ryzen, AMD introduced their own compiler: AMD Optimizing C/C++ Compiler (AOCC).

Microsoft will only support Windows 10 for Zen. Linux added initial support for Zen starting with Linux Kernel 4.10. The move to 14 nm will bring along related benefits of a smaller node such as reduced heat, reduced power consumption, and higher density for identical designs. The jump to 14 nm was part of AMD's attempt to remain competitive against Intel (Both Skylake and Kaby Lake are also manufactured on 14 nm). AMD's previous microarchitectures were based on 32 and 28 nanometer processes.
