Increased latency will reduce the performance and potentially eliminate the gains from a higher frequency, depending on the size of the frequency increase. This increases the time (latency) between operations, and helps to keep the transfer stable.
To counter-balance stability challenges at high speeds, memory timings are often increased. Simply put, when a memory module operates at a high frequency, it is more difficult to keep it stable. The two have to be considered together to determine the overall performance of RAM.Ĭompromises usually need to be made in order to raise one or lower the other. So it seems like there will be no problem.In an ideal world, RAM would have high frequencies and low timings. Ok, so a few days later and I have checked the mobo. Micron might tolerate higher heat than Samsung, but Samsung IC's might handle higher voltages/current than Micron when kept cooler. As for the vDIMM required to kill the IC's on your ram, it varies from IC to IC. As long as you are under 1.25v each (personally I avoid going above 1.15v each, but to each their own) you should be perfectly fine for the long term. Different motherboards will set a different auto-value for these two voltages, which is why Intel was worried. This statement is still true, but not with vDIMM. Intel's original statement was "high voltage kits can kill Skylake's IMC". It boggles the mind to see how many of these news outlets refer to them as tech outlets or hardware outlets, but know very little of how things work. It was the news outlets fault for not doing their own homework, and regurgitating things they do not understand. It's far easier for them to say "don't use high vDIMM kits" because typically, high vDIMM kits run at higher speeds, and require more VCCIO/VCCSA to stabilize when using auto settings. It wasn't misinformation, it was a gross over-simplification of the process. To further support the claim that they lied, I have been running this setup for a few months now without a single sign of instability, I was just playing around in the BIOS one day and found that the info page on my motherboard said the ram ran at 1.5V and got worried. Thanks guys! You saved me ~80 dollars, I had no idea intel has tried to spread miss-information, it even looks like they have deleted their original statement cited in multiple news outlets.
