Platypus攻击可从Intel CPU中窃取数据 近日,研究人员发现一种名为Platypus的新的攻击活动,可以对Intel 处理器的RAPL接口进行攻击。 近日,研究人员发现一种名为Platypus的新的攻击活动,可以对Intel 处理器的RAPL接口进行攻击。RAPL 表示运行平均功率限制(Running Average Power Limit)是一个允许固件或软件应用监控CPU和DRAM...
Remember that RAPL is "Running Average Power Limit" is a "running average". If you set the averaging interval to equal a single sample, you will not actually be averaging anything. Setting both limit #1 and limit #2 to use the same single-sample "averaging interval" might provide weaker...

The use of the Running Average Power Limit (RAPL) processor capability (see section 14.7.1) is highly recom- mended when HWP is enabled. Use of IA32_HWP_Request.Maximum_Performance for thermal control is subject to limitations and can adversely impact the performance of ...
power in a very straightforward manner, bypassing the idle power problem entirely and just not running the iGPU when it wasn’t needed. While there is a small amount of overhead to waking the iGPU up and putting it back to sleep, the relative power savings from DCC were close to the ...

Power_gov fails in my system to initialize, it gives "RAPL not supported, or machine model 306e2 not recognized.Init failed!" In BIOS DRAM RAPL BWLIMIT =1 and DRAM RAPL (Running Average Power Limit ) Mode = DRAM RAPL Mode 1]. Any idea why power_gov fails? Translate...
This value is then compared to the long term and short term turbo power limits. This is how the CPU determines whether it should be using turbo boost or not. The turbo time variable is an approximation. After a fixed amount of time running at the higher power limit, the CPU will switch...
I do not believe 14900K's will clock any better than 13900KS does, that remains to be seen of course but the preliminary benchmarks seem to place it identical in single-thread and slower in multi-thread (because it comes with the standard power limit instead of the 150W-type extended...
GeForce RTX 4090. All performance enhancing options for the CPU were enabled where available in the BIOS, including Dynamic Tuning Technology, and the system's DDR5 was clocked to 5,600MHz with timings of 40-76-76-76. The RTX 4090 was kept at its default frequencies and power limit. ...
