I know that the increase in idle is normal but what don't find normal is the huuuuuge drop it gets without LLC. I mean, I thought judging from the load voltage on my reference one that with 1.300v it should be at about 1.27-1.28v.
The obvious reason for this higher drop would be the fact MSI does indeed use different VRM's and FET's but k.
I got my memory OC'd pretty high but when not using LLC the OC holds up just fine. No artifacts, score scales with memclocks so no hitting ECC just yet (It does hit ECC on 1900Mhz as the score in Valley actually drops ~40 points), no FPS drops or whatever to indicate ECC or failing VRAM..
But, you're probably right about 1.294v load not being a good choice on air lol.
I'll stick with 1.300v setpoint (1.288v idle, 1.238-1.244v load) on 1320Mhz as 1320Mhz on <1.25v load is quite good really judging by what I read on here on average.
Especially paired with 1800Mhz VRAM clocks (which are obvously Samsung) i'm happy
My dead(yes I was the owner of the dead Palit Jestream
) card was doing 1359/1785 stable at Valley with custom bios and MSI AB voltage set to 1.3V. BUT
under load the actual voltage as reported by AB was 1.256V iirc.
So the MSI Gaming doing 1320 and maybe firstname.lastname@example.org load, that pretty damn amazing! Just enjoy your beast. That's a lot more than what the average 780 clocks are.. Its a shame to "lose" a card like that.
I would had settle at 1.225-1.238 for max gaming performance if needed. Even @1.21V is not that bad. I'm sure you can do easily 1280Mhz@1.21V. And thats a remarkable clock to be gaming at!
From your reports I might even consider getting one and hope to clock as good as yours or as my last Palit JS..

It´s normal as disabling LLC gives you 0.006v increase in idle clocks

."Remember that a 780 died last week on ar at 1,27v... stay under 1,25v with LLC disabled on air
"So, VRM temps, still possible, but unlikely
VRM´s more specifically mosfets have a temperature and voltage trip that lowers its logical state when certain temperatures and/or voltages values are reached, also you have a PT trip that does the same, one of its symptoms is stutters and the dreaded throttling!
What bios are you using? Skyn3t´s or stock? if you have memory OC back it down, it is known to cause reboots!
I know dead gpus dont happen everyday and many people will call those who kill them "fools", but when it happens to you and you are put in that position you understand a few things and "fool" is not in those.
And you are also left with a 500+euros paperweight.
So once more guys, know the risk of going over 1.25-1.275 on air and REMEMBER that if you disable vdroop/LLC it ADDs 0.25V on top. So 1.25+0.25= about 1.275-1.28V. Keep that in might and Overclock SAFE.
