Memory mhz ?

[asger-p]

Hi

When I read the spec for i5-9600k or any other new Intel processor they all say ddr4-2666mhz

I can see there are ddr4 memory blocks with values from 2133 to 4000 and the same on the motherboards.

Are there any benefit to choosing values higher the 2666 ?

Thanks in advance

Best regards

2666 is the official JDEC supported by intel and the IMC. Anything above that is considered an overclock and may or may not work. Generally, you should have no issues with any ram up to 3200mhz for XMP and anything beyond that is when things potentially can start becoming a little unstable and require some tweaking of timings to get them stable.

same benefits as overclocking the CPU, but less significant unless you're on Ryzen. However memory overclocking is more complicated, as memory timings (which has a lot of extra numbers involved) also affect memory overclocking.

Depending on how much faster you go is gonna decide whether you "notice" it.  And even then you would probably need to be using something that quantifies speed in some form or fashion.  For your day-to-day tasks, however, you almost certainly will not notice the difference.

since you are looking at the 9600k i'm assuming ur gaming, i'm just gonna quote der8auer: get something between ddr3600-4000, you won't see any difference beyond that.

 

As for actual gaming performance, you'll probably see 1-2% higher average and 1% lows on frame rates from 3600 to 4000, maybe 3-4% from 3200-4000.

 

When is 3-4% practical? probably the last bit of frames on high refresh monitors, for a 8700k/9900k oc'd at 5.2/5.0 respectively, as silicon lottery has demostrated, people pay alot for top end performance, and ram is imho the cheapest way to minmax. (maybe 100dollars more for 16gb)

Thanks for answering
I should have mentioned that I don't game at all, but I do a lot of 3D CAD with lot of parts, but no big rendering tasks.
i5-9600k is chosen especially for that reason as it has a high single thread performance.

 

As I understand your answers:
I can by any ddr4 memory between 2666 and 3200mhz as long as it physically fits, right ?
