News MSI introduces Latency Killer to improve DDR5 latency on AM5 motherboards — feature reportedly reduces latency by up to 8ns

[Admin]

MSI has introduced a "Latency Killer" performance enhancer that purportedly reduces DDR5 latency by up to 8ns. This feature was added to counter latency degradation that was introduced with AGESA 1.2.0.2a

8ns is a lot. I only get a bit over 10ns under XMP by tuning my Intel system.
It is a shame that nearly everyone else who has a Ryzen has had their performance degraded like this.

Hopefully someone can figure out what MSI did so others can have their performance restored.

8ns is potentially a pretty big deal, but it also depends on when this additional latency occurs. If it's only when using mismatched clocks then it probably isn't relevant to the vast majority of AM5 users. This seems like something that might be worth investigating unless AMD themselves have already addressed it.

I will say MSI has been making some pretty big strides on simplifying memory tweaking for both AMD and Intel lately. Makes me wonder if they're just diversifying or if they're going after Asus.

I'm pretty sure this is referring to overall memory latency that you see in memory benchmark tools, not just the "first word" latency on the memory spec. Overall latency will typically be around 60ms for highly tuned systems and probably up in the 80-90ms range otherwise so while the number isn't large, a potential >10% latency reduction is nothing to scoff at.

Ms? Or ns? Lol

8ns compared to what?

There is nothing substantial in this whole article, just regurgitating some irrelevant information nobody can relate or compare to anything because you didn't understand the topic in the first place.

There are so many different latencies when it comes to memory, just saying "8ns" doesn't tell us anything...

ns = nano second.

If memory was in the milliseconds, your PC would be unbelievably draggy...

You are multiple orders of magnitude off.

Whatever MSI have done, I'm sure AMD and the other mobo makers will soon reverse engineer and copy, especially if just micro-code tuning.
