Alienware 17 R1 4930MX OC Throttling. Know the issue, how to fix?

Ok so as the title says, I've spent the day trying to figure out my 4930mx. Had some success. But thanks to @unclewebb and throttlestop with the "limit reasons" app, I now know that I am getting thermal throttling due to VRM temps.
So I have a good basic understanding of i7 cpus and overclocking limitations as I have owned 920xm, 3820qm 3770k and 4770k. I have solved the power and current throttling issues, now this VRM temp issue appears to be my next roadblock. No matter what clocks/voltage and power settings I use (3.9 - 4.3ghz etc) I seem to always get the same scores and throttling (942 XTU or less).
So heres my thoughts... If I can find a way to cool the VRMs I should be able to get the full 4.3ghz range I want out of this chip and see those 1000 XTU mark scores that only a couple people have touched on.
So:
-Are the VRM's onboard the CPU die on 49XXmx chips?
-If the VRMs are outboard (on the motherboard) should they not be making contact with the heatsink through a thermal pad or something? The AW17R1 does not have a thermal pad between the cpu heatsink and the motherboard at all so this makes me think this is my issue.

This screenshot should help make sense of what Im saying. The orange graph bar at the bottom is the CPU core clock speed. Every time the VRMs get too hot it throttles back to 3100 mhz or so, then back up and cycles this way over and over under heavy load.

 

Ok so first issue I noticed since this and fixed. My CPU core voltage was set to adaptive. I changed it to static. 1.175v Everything seems to still be stable however I am still getting the VRM throttling. Every source for information I can find on haswell cpus seems to say the VRMs are internal in the CPU die... so how is it possible my VRMs are overheating when my CPU is clearly staying under 90*C?

I have also noticed it takes me more current limit to maintain 4 ghz. I have to use almost 155A Processor and 135A Core to keep the cpu from current throttling. I assume this has something to do with my extra heat and throttling but what am I doing wrong to cause this?

If I use less than 1.17v my system will crash, power off then reboot back to windows. No BSOD just crash.
Maybe some advice @Mr. Fox please? Huge thanks for everyone's time!

 

@loafer987

Did you ever resolve this? I am having the exact limit reason in Throttlestop but in HWINFO I am getting Power Limit Exceeded, Im not sure if these are linked though.

I tried setting 256A to proc and core since papusan mentioned it was a magical number but the behavior is still the same.

EDIT: I realize its an old thread, so Ill apologize in advance for reviving it.

 

No problem. I never did solve it no. I believe the issue is the AW 17r1 doesnt have the power supply for and cpu that the aw18 had. if you look at pictures the aw17 only has 2 or 3 phase power input when the 18 had 5 or 6 I believe. double the power and current capabilities of the 17 in regards to the cpu. I believe the external VRMS (on the motherboard) are being throttled by the bios or laptop to prevent VRM damage on the motherboard. A laser thermal gun would probably let me test that theory but its hard to run the laptop upside-down safely and test these types of things. I just settled on 4 ghz and an undervolt to 1.16v (my cpu was 1.24v stock I believe)

 

Hey man thanks for sharing.

I know of one member running his at 4.2Ghz but can bench I think at 4.3Ghz

I ordered some mosfet copper heatsinks and plan to place them on what I believe to be the VRMs (under the heatpipes) and fit thermal pads to the top to make contact with the heatpipe (for the ones that I am able). I am hoping this may mitigate the VRM heating issues and allow for overclocking past 80w

Unless the VRMs are in a different location?

I'll let you know if this scenario plays out in my favor, if so then it might be worth exploring on your own system in the future

 

I get vr issues on my 4930mx as well but since I am able to keep my cpu at 81c or below I am able to complete a cinebench run at 4.3ghz and I can run the cpu at 4.5ghz or better in game. It just is of no benefit so I don't because of the extra heat. The 17r1 can handle more than a 300w power draw and it may not have as robust a power delivery as the 18 but its the better laptop. I'll make a thread on my cpu discoveries tonight.

 

You've been an invaluable resource as always man, I look forward to your thread when you get the chance to make it!

I tried running 4.0ghz but I still get vr therm limit at some points
