I had to give up on the idea of AB allowing voltage control on my MSI R9 380 4GB...the newer version AB is the same...everything is set properly to turn it on. But get this...Strixx 5.2.1 has no problem with regulating voltage at all. I have a monitoring proggy that I run when I run Strixx so I know it is actually doing what it says it's doing. In AB the voltage slider is simply locked...the fact that it works immediately in Strixx with no tinkering on my part indicates that my card is not bios-locked or hard-wired against permitting voltage manipulation. My guess would be that MSI is doing that, somehow, inside the software, for obvious reasons--who wants to do RMAs on voltage-abused cards? Still, I suppose it's the idea--the principle of the thing...So I guess it's Strixx from here on out.

Makes little sense really. I just installed the MSI 380 (I only have the 2GB model though). Voltages are working right out of the box after installation. Unlock voltage is enabled in the preferences ? And also are you running the stock BIOS ? If so, let me know the device ID (click the 'i' button and copy/paste the part where it says VEN_1002). See screenshot of the MSI 380 2GB here of the voltage enabled + example Info: http://nl.guru3d.com/ab420-r80-2gb.jpg

Thanks for responding HH! I am very appreciative. I agree it's nuts...don't understand it. Bios is stock. I like and prefer AB--that's the one I've used for a long time and would like to continue to use. I remember your review of the 2GB card and in fact asked you how you were getting a voltage unlock--and if maybe the 4.2 betas (at the time of the review) were freeing it up for you. You were gracious enough to give me the link to the 4.2 betas then, and told me that you weren't aware of any new ATi code in them--and I tried them and you were correct. Didn't make any difference for me. So naturally, I figured my MSI card was just voltage-locked and it was something I'd just have to grin and bear--(like that would be a real trial or something...;) It would not be.) Then today I decided to give Trixx a spin--and boom--worked immediately.

Anyway, I'll be more than happy to email them to you, if you believe they'd help! Thanks much for your interest & response, HH...I like these little mysteries, actually--especially clearing them up...;) Thanks again. I've clean installed AB twice and double-checked the settings--both in the GUI and in the AB settings file...voltage control is set to 1. I even fully rebooted to make sure that the setting was being picked up--it should have been. Also, when the AB voltage control is set for +100, as caught in your screen shot, is that 100mV--or a percentage? edit: never mind--has to be +100mV, of course...;) (Long day.) Thanks very much...I'll look for your suggestions! (I'm trying to hit your overclock targets with the 2GB card.) Edit: I forgot to mention that although I am using the Crimson drivers, I am running them through the 15.11.1b CatalystCC--which is far more functional than the Crimson interface. (Why AMD decided to number the Crimson package with the exact number of the previous CCC beta, I have no idea--but I don't understand much about why they did practically anything they did with Crimson.) Afterburner picks them up as the standard Crimsons--as it should.

LN2 Mode Did you include VendorID for Lightning using LN2 BIOS as well? The ID is different compared to Standard BIOS. I´ve not yet downloaded updated AB 4.2.0. Therefore I´ve modified oem2-file with the matching ID to use expanded options of AB. PS: Any update regarding offset-mode?

As you can see DEV_6939 that's Tonga ... and the ID's match mine. Long story short we have the same hardware other then you have 2GB graphics memory more, AB is doing nothing other then applying what is possible with the driver. The card is supported, period. So the only thing left is a software setting or driver conflict somehow. Would you happen to be in a household with another PC ? I think you'll see that once you inserted it into another PC and install AB, you'll get voltage control right from the start.

Hey man. I'm not going to use the voltage control on my card, but, since we have the same card I went ahead and tried enabling voltage control on MSI Afterburner and it does work (standard MSI). My card BIOS (stock) is more recent tho. I think you might be, but are you clearing the MSI Afterburner settings between installs? http://i.imgur.com/Zetv1Kz.png

Yes, and thanks again for the comments...something is strange...I neglected to mention that my motherboard is also MSI--an MSI 970 Gaming with the latest bios (UEFI) 22.3! I wonder if that has anything to do with it. Win10x64 version 1511, UEFI install, and am running the Crimsons in UEFI mode, too. I did push things with the trixx software--added 80mV and could bump the clock to 1150--at 1.2GHz I got artifacting with 100mV added so I backed down and am stable now. Thanks again! I'll keep looking and if I find anything I'll be sure and come back and make a note of it (for the benefit of anyone else who might have a similar problem)...;) I think the AB software is great...and I've used it for years--it has to be something local.

It's possible I have a card bios problem...what is your bios version, if you don't mind me asking? Yea, I've tried everything, including clean AB installs, more than once. That's what is so baffling--why Trixx but not AB? Presumably they are doing exactly the same thing--I would guess.

I remember reading a post by Unwinder saying that using the Fury in UEFI wouldn't allow the voltage control in AB (or was it the HBM clock? Hum) Maybe it's the same for other AMD cards? Later I saw that Hilbert has an older BIOS than us both so it shouldn't be that. **edit Here it is: http://forums.guru3d.com/showpost.php?p=5202798&postcount=55

Thanks, s0x...I even reflashed my vbios yesterday just to test--no difference after a successful reflash. I remembered reading something like that myself, but wasn't sure if I'd read it right. But that is exactly what Unwinder said... I noticed that in the 380x 4GB review recently that the screen shots there do not show the voltage regulation either being on or working--unlike the screenshots in the 2GB 380 review that HH was kind enough to post in this thread. That makes sense to me, really, because if the issue was hardware then Trixx would not work, either. So it has to be a software issue--and according to that Unwinder quote, it would appear that maybe I have my answer. Perhaps in the 2GB review HH was using a Legacy system instead of UEFI--if so, then that would explain everything. Odd, though, that Trixx works in a UEFI setting to unlock and manipulate voltage control, but apparently AB will not--if we are both reading his quote correctly! Thanks again--I think this solves it...:)

Custom Fan curve is not working for me on 4.2.0, I had to roll back to 4.1.1 The fan stays in a fixed speed, when the curve is active, I can manually change it, or set to Driver Auto, but when the Fan curve should kick in, it does nothing (although it disables Driver Auto settings, so there is a concern there...) Windows 10 x64 GTX 970 driver 359.06 I will skip this version while keep updating RTSS.
