RAM won't go past XMP settings

Corsair VENGEANCE RGB PRO 2x16GB DDR4 3200 C16
ASUS ROG Strix Gaming-i z390
Intel 9700k


I have a rock solid, manual OC on the CPU @ 5.1ghz, 1.36 CPU core. BCLK is at 100 and ratio is 100:100. CPU VCCIO and CPU System agent both set to 1.1V per a CPU overclocking outline I followed (could either of these be the culprit? Better set to auto? Do these even affect my CPU overclock?)


Memory settings are manually set to XMP values and I cannot for the life of me touch anything related to the memory at all or the PC won't even post. 1.3625V on the DRAM and I can't raise frequency to even 3300 nor can I lower CAS to 15. Straight 3200, C16 @ 1.35V is all I can get. I've read C16 3200 RAM is generally the weakest overclocking RAM out there - is this just all I will get?
 
It's possible that is all you can get, but it's unlikely. What happens when you change the Cas to 18 and try for higher memory speeds?

You're right, I haven't tried everything. I've been too focused on said voltages, maybe I'll leave voltages alone and loosen timings a bit.
 
I dropped CAS to 17 and other subtimings by 1 and was able to get frequency up to 3400 all other things equal...but I feel like that's a wash most likely? Raised DRAM voltage, VCCIO and SA voltage incrementally until it was unstable without any increase in frequency either. I'm comforted by the fact that this CPU is not as dependent on frequency as Ryzen but I'd still like to see some more headroom than this. I am using Prime95 to stress test and then Cinebench single core to bench the CPU. CPU score is not changing no matter what RAM settings I'm using, how can I bench the memory? Passmark? I have a hunch that none of this is having an impact.

From what I noticed with ram outside stuff like B-Dies you pretty much get what you paid for with very little wiggle room with ram nowadays. Between the 5 set of ram between AMD and Intel systems over the past couple years wouldn't budge past their rated speeds. Lowering the case for more frequency does work but like your said it becomes a wash when you have to do that. I guess most the major players bin their chips hardcore so they can mark up their premium kits to the moon.

Agreed. I bought this RAM essentially for the RGB, I had a faster G Skill RGB kit but refused to install its software just to match the lighting on my keyboard / mouse / AIO (all Corsair).
 
give it more juice. they can handle +10% voltage no problem. every corsair kit ive ever used needed more voltage to be fully stable.
 
You can do 1.4V without problems.

Im currently running a Vengeance LPX kit 3200 C16 at 3200 C14 and even tighter timings than XMP with minimal voltage... 1.38V
 
Do Asus Intel boards have a sub-menu with Boot RAM voltages like Asus AMD boards? Poke around the sub-menus and look for a Boot RAM voltage setting. It's separate from the main DDR4 voltage setting at the top level.

what? ive never heard of that, interesting...
google shows several pics of ROG bioses with it. so it might be worth looking and trying.

I would be happy to try it with 1.45v but depending on the chips it may or may not scale with the extra juice.

dont worry about "scaling" for now, just get it booting.
 
Run thaiphoon burner and find out what ics they run. It may clear things up as far as what you can expect out of them compared to what others have gotten.
