【求助】5820k过p95无法跑AIDA FPU Mendel测试，这是神马情况？

朋友有颗5820k，4.6 1.25v过AIDA FPU Mendel和p95 27.9，47 1.25过FPU Mendel，1.2995v过p95 27.9，电压高于1.25v运行FPU Mendel直接重启。
单条内存可过测试，4通道不行，SA加压无效，IO 1.05这是什么原因？

4.6 内存2133可过任意测试，内存Ripjaws 4 XMP 3200无法过测试。IMC问题，为何SA加压无效？

注：FPU Mendel是个双精度测试

暂定IMC问题，的确与内存频率挂钩。改日再战！同步更新

我的主板是X99 SOC champion  5820K 先后易迅买过一颗，京东5颗，只有一个可以，其他5个都是不行。另外还要看内存的体质的。。。

内存 XMP 3200 尤其是四根想过测试，必须U的IMC够强加上主板支持！

IMC体质得够好，内存供电和电路设计要过硬。

问题来了，这个锅由谁背，主板or内存？暂时无更换硬件计划

感觉像是IMC不够强，降低一下RING频率、内存频率再试试。

超ring和内存收效不是很大，也不用纠结呗，呵呵……

Benchmarking

Benchmark pages of AIDA64 Extreme provide several methods to measure system performance. These benchmarks are synthetic, so their results show only the theoretical (maximum) performance of the system.

CPU and FPU benchmarks of AIDA64 Extreme are built on the multi-threaded AIDA64 Benchmark Engine that supports up to 32 simultaneous processing threads. It also supports multi-processor, multi-core and HyperThreading enabled systems.

Ray tracing benchmarks

These benchmarks measure the single and double precision (also known as 32-bit and 64-bit) floating-point performance through the computation of a scene with a SIMD-enhanced ray tracing engine. The code behind this benchmark method is written in Assembly, and it is extremely optimized for every popular AMD, Intel and VIA processor core variants by utilizing the appropriate x87, SSE, SSE2, SSE3, SSSE3, SSE4.1, AVX, AVX2, XOP, FMA, and FMA4 instruction set extension. Both FP32 and FP64 Ray-Trace test is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware.

Memory Tests

Memory bandwidth benchmarks (Memory Read, Memory Write, Memory Copy) measure the maximum achiveable memory data transfer bandwidth. The code behind these benchmark methods are written in Assembly and they are extremely optimized for every popular AMD, Intel and VIA processor core variants by utilizing the appropriate x86/x64, x87, MMX, MMX+, 3DNow!, SSE, SSE2, SSE4.1, AVX, and AVX2 instruction set extension.

The Memory Latency benchmark measures the typical delay when the CPU reads data from system memory. Memory latency time means the penalty measured from the issuing of the read command until the data arrives to the integer registers of the CPU.

CPU Queen Benchmark

This simple integer benchmark focuses on the branch prediction capabilities and the misprediction penalties of the CPU. It finds the solutions for the classic "Queens problem" on a 10 by 10 sized chessboard. At the same clock speed theoretically the processor with the shorter pipeline and smaller misprediction penalties will attain higher benchmark scores. For example -- with HyperThreading disabled -- the Intel Northwood core processors get higher scores than the Intel Prescott core based ones due to the 20-step vs 31-step long pipeline. CPU Queen test uses integer MMX, SSE2 and SSSE3 optimizations.

CPU PhotoWorxx Benchmark

This benchmark performs different common tasks used during digital photo processing.

It performs the following tasks on a very large RGB image:

• Fill the image with random colored pixels
• Rotate 90 degrees CCW
• Rotate 180 degrees
• Difference
• Color space conversion (used e.g. during JPEG conversion)
  

This benchmark stresses the SIMD integer arithmetic execution units of the CPU and also the memory subsystem. CPU PhotoWorxx test uses the appropriate x87, MMX, MMX+, 3DNow!, 3DNow!+, SSE, SSE2, SSSE3, SSE4.1, SSE4A, AVX, AVX2, and XOP instruction set extension and it is NUMA, HyperThreading, multi-processor (SMP) and multi-core (CMP) aware.

CPU ZLib Benchmark

This integer benchmark measures combined CPU and memory subsystem performance through the public ZLib compression library. CPU ZLib test uses only the basic x86 instructions, and it is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware.

CPU AES Benchmark

This benchmark measures CPU performance using AES (Advanced Encryption Standard) data encryption. In cryptography AES is a symmetric-key encryption standard. AES is used in several compression tools today, like 7z, RAR, WinZip, and also in disk encryption solutions like BitLocker, FileVault (Mac OS X), TrueCrypt.
CPU AES test uses the appropriate x86, MMX and SSE4.1 instructions, and it's hardware accelerated on VIA PadLock Security Engine capable VIA C3, VIA C7, VIA Nano and VIA QuadCore processors; and on Intel AES-NI instruction set extension capable processors. The test is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware.

CPU Hash Benchmark

This benchmark measures CPU performance using the SHA1 hashing algorithm defined in the Federal Information Processing Standards Publication 180-4. The code behind this benchmark method is written in Assembly, and it is optimized for every popular AMD, Intel and VIA processor core variants by utilizing the appropriate MMX, MMX+/SSE, SSE2, SSSE3, AVX, AVX2, XOP, BMI, and BMI2 instruction set extension. CPU Hash benchmark is hardware accelerated on VIA PadLock Security Engine capable VIA C7, VIA Nano and VIA QuadCore processors.
