Didn't touch voltage at all since I'm using the stock Intel cooler. No blue screens or signs of instability after an hour of Aida64 stress testing, so I think it's stable.
You should, since that voltage is probably enough for 4.4Ghz...
Ok. Thank you so much.
I have to do some research now
Whatever you do, we are here to help you, so either way we will sort it out
Say you did buy 3000Mhz Ram, but only could get it to boot at 2666Mhz. You do the following:
Find the same RAM kit at 2666Mhz. Look at the specs online.
Identify the Primary TImings, usually 2666Mhz is like 14-14-14-32 2N
Identify the RAM Voltage, usually between 1.2v to 1.35v.
Enter the above found settings in the BIOS, and see how it goes. If it boots then you just need to stability test a little with Prime95, Realbench or Aida64, i do a mix of each.
What you wouldnt want to do is this:
Buy 3000Mhz RAM, Apply XMP Profile 15-16-16-16-36 2N
Set Frequency to 2666Mhz for 2666Mhz @ 15-16-16-16-36 2N -> As this would result in lower performance than a normal 2666Mhz kit, probably perform between a properly set 2133-2400Mhz kit.
You want to have optimum ram timings for each frequency. If you compromise too much on Freq or Timings, then you just lose performance (bandwidth/latency), must balance both. Just so you know, higher timings, mean more latency, so by tightening we mean to lower timings. Too tight and the RAM wont be able to function correctly. Too fast and the RAM wont work properly either.
Now i doubt you will run into much trouble at 3000Mhz and lower speeds with just the above tweaks, but if so, youll need to tweak the VCCSA (System Agent voltage), which is the voltage for the Intel Memory Controller in the CPU. This sometimes needs more juice, but usually the Boards AUTO setting is good enough to figure out a good value based on RAM Frequency. I think stock is around 0.95v, and anything up to 1.20v is fine.
