When I ran mine at stock 2133mhz I left this ram current alone, @ 2400mhz I had 120% for a while and it was rock solid, then I changed to 110% and after some time (~2 weeks) it started to act weird, right before logon it would bsod or rest pc.. After I put back to 120% it stopped and haven't seen it since.
But now its using more wattage, always min 20w, at stock 100% I think it was a lot lower, 5-6w or so.
btw whats vDIO, digital IO cpu voltage?
EDIT:
So I could run mine at ie 110% too, but I would need to adjust this vDIO?
Although I already played with this DIO once, but idk how to set properly, I set it 50mv more then analog but it didnt help much.
Im also using vccsa 0.045v atm @ 4.6ghz, had 0.040v but now at 0.045v i noticed i get better fps by cpu bound game benchmarks.
yep, digital I/O voltage. stock is usually around 1.02-1.05 for most chips I've seen, but I've seen BIOS default to higher. I know that for me to be able to push those 3000MHz + clocks, 1.2V DIO is essential.
So, I tell you my story about this:
I am testing 4790K test further, and find that up to 2400 Mhz boot, no problem. 2600/2666, no go, and I got ram rated for 3100 MHz...WTF!?! Try other memories, nothing over 2400 MHz is working, and when I do get 2666 working, bandwidth is garbage...just worse than 1600 basically, but with OK latency...OMG why is this so hard when it was so easy a year ago? Swap in a few boards, try other things, pull down MSI Z97 Mpower, start ticking off the voltages, one by one...
So, I check back in my notebook as to what I was setting way back when I was pushing 3400-3600 MHz on my review 4770K, since I decided to use 4770K and see what's what, since my ES 4790K has some damage, and remembered after some time of no luck (like a week off playing with settings) that IO's on 4770K needed 1.25V, or no boot...but here I am @ 2600 with no boot? So I push up to 1.25V...it works fine.
Slowly lowered it until no boot re-appeared, and this began @ 1.125V. But, I could warm boot, just not cold boot. So push a bit higher, 1.15V, cold boot, warm boot, both no problem, from 2600-3200 MHz. But full stability... that took just a wee bit more, up to 1.185V....
I am not sure what this DIO, what it's for. Like, I got some ideas, but documentation and such is so sketchy... So that's where I'm at right now. almost every board, no matter the brans, over 2400 MHz..there's ZERO bios tuning. MSI has some nice profiles to use, they work great. ASUS, tertiary timings are garbage, and they say "oh, you try set 8 for everything, and then lower and test". Yeah, right. If that worked, BIOS would already been tuned like it was over a year ago, new BIOS programmer isn't doing it fully, or is a noob. Check Gigabyte.. same story. ASRock...yeah, they need some work too.
Anything up to 2400 MHz, no problems.
That said, with al lteh testing I've done, I'm getting pretty close to being ready to write my next guide.
When we went through the OC on your sticks, seemed to me that your CPU was the limit preventing you from getting higher.
