I'm curious of this as well... I have always set phase control to "ext perf" on my board, the gigabyte z87-oc. Also I can't find any settings in the bios to alter the max power draw. I noticed in XTU it's possible to up the limits.

Edit: Finally starting to hit 80's after running cpu miner at 100% and gpu miner...

Vdroop is a relic from the past, necessary when our PSUs and Mobo's had poor voltage regulation under transients. It's not an issue to see voltage move slightly away from nominated values, as long as the movement isn't extreme (which with high LLC, doesn't occur)

IMO, the best choice is to have tight LLC so that voltage sits as close to your nominated value as possible. Having voltage move higher under load is fine as long as you understand it's going to happen and set your idle voltage lower, which won't be an stability issue since you're idling lol.

I'm curious about your first statement. If vdroop is a "relic from the past", then why does my motherboard have a specific setting for it? thinking.gif

Higher LLC reduces/eliminates voltage droop. Weaker LLC introduces voltage droop.

Vdroop options exist by request of manufacturers to safeguard from extreme scenarios.

The Auto settings should be dictating very limited vdroop by default. There is no reason why people should be manually adjusting these parameters to introduce vdroop. It just doesn't make sense to do it.

Edit: by "extreme scenarios", I'm referring to extremely bad scenarios, when someone is using some 10 year old PSU or a 50 dollar z87 mobo with low complexity, low quality, analog power phases

So much for 4.9 ghz... even with 1.5 vcore still got 101 bsod frown.gif

Mine is stable at 4.8, temps never go above 76 C load. Not sure I would add any more than 1.5 to the vcore...

Here's my numbers on water at stock speeds if ya find it useful.

Idle / Max
Core 0 26 54
Core 1 27 56
Core 2 26 49
Core 3 26 48

and at 4.6 Ghz
Idle Max
Core 0 30 74
Core 1 29 73
Core 2 28 70
Core 3 27 65

Core Ratio same as CPU multiplier in both cases

But my tests were run using adaptive voltage control and RoG Real Bench .... P95 under adaptive not recommended.

Let me know what you guys think. Did a very high test run on Intelburn at 4.6ghz. I set VRIN to 1.9V, Vcore to 1.24V, and turned off XMP and set to 1600mhz. I was concerned that Coretemp went unresponsive a few times as I have that program set as my overheat protection... I was running my two XSPC 140mm fans at 100% throughout the test mounted on my EX280 rad with Raystorm block and D5 pump set to 2. (Note: I have been running 4.5ghs stable for months with a VRIN of 1.7V and just want to see how far my chip will go)

Charted. What heatsink, batch, ram setting?

You've only run realbench for one hour. While you might be stable, I recommend running it for a longer period of time.

Cheers

You've already been charted, but I'd be careful of going any higher on that Vring.

Nice one you good to go . Now try to reduce your Vring bit by bit i might say by 0.05. cheers. find the lowest voltage as good as possible.
