Coffee Lake + 3333MHz CL16: avoiding SA & VCCIO tweaks

[TheF34RChannel]

I've been asking around but I'm afraid my question got lost in the plethora of posts that followed, understandbly. I've got the above combination coming on a Z370 (Apex) board (+ 8700K).

Having watched Tom's CPU review I'm kinda annoyed with myself for openng the packet a day before I watched the video (oops) as I after realised that 3200 CL14 is the sweet spot and you can (theoratically) just enable XMP without messing with voltages.

I was wondering which of the following routes will be neccesary to take for me (in all likelyhood) with the 3333MHz set:

a) Enable XMP and since it's so slightly over 3200 the SA & VCCIO won't need tweaking;

b) Set up the frequency, timings, DRAM voltage manually and thus avoid the board auto increasing the SA & VCCIO (?)

I really do not want to play with the SA & VCCIO voltages, it's not for me.

Enable XMP first and then check the voltages anyway as they often get set too high with any memory.

Will do Kaap, thanks. What are the normal ranges of those voltages? Embarrassingly I don't know.

Whatever the voltage is for your memory is what you should stick with. If it says 1.25, stick with that. I don't see a real point in going past what your kit is rated for. I've never had a kit that did more than advertised even with more volts.

I think there's a misunderstanding; I don't plan on overvolting it. I don't want to play with the SA and VCCIO voltages because my memory is 3333 and am asking if I can avoid that somehow.

Id manually set them and work on lowering them no matter what if I were you

I hear you, however that's exactly what I'd like to avoid; I dislike messing with memory voltages so much (past experiences ha ha). But, it seems I have no choice ha ha! Thanks, and I'll manually set all primary timings, voltage and frequency.

Use the XMP profile to get the timings and then it is just a case of lowering the voltages manually.

Will do!

It can really aide in controlling temps if you take the time and get sysagent and vccio dailed in. Really helped my 7700k but I still delidded anyways cause I wanted 5 GHz nice and cool.
