How important is CAS on Z390?


Recommended Posts

I'm looking for a 2x16 32GB 32000MHz kit for my i7-9700K build. Is it worth paying £50 more for CAS 14 vs CAS 15?

no, not worth it. 15 is already good and you might be able to oc them to 14 with a little more volts, like 1.375-1.400v

What I'm looking for is memory to complement my i7-9700K and GTX1080Ti but I'm not planning to OC the memory initially. Only as the system gets dated would I want a good OC from the memory, I'm looking for modules with Samsung B-Die chips.

 

 

 

As a rule of thumb which of the following 32GB 2x16 kits would you guys consider:

3000 CAS16 £250 (non B-Die)

3000 CAS15 £275 (non B-Die)

3000 CAS14 £350

3200 CAS16 £280 (non B-Die)

3200 CAS15 £350

3200 CAS14 £380

yeah..I mean..if you have those extra 30, go for the 14ers. 350 for 32GB is already a rip-off, so why not get completely robbed but be left with a smile.

 

Hope the board likes them or you end up like me with 3600-16 only doing 3000-16.

 

 

Bottom line, you wont notice and you wouldnt notice if I had all RAM above and would let you test them all in DCS. You would feel ZERO difference across them all. It's all hobby and men and their toys but not a real value.
