Even though the 260X is confirmed by AMD to not support dual graphics. Does anyone have speculation about future updates and possibility of future DG with it? I'd like to fiddle around with my Kaveri on Dual Graphics but if 250 is the highest it will go ever then I guess no choice. Most likely wishful thinking on my part but what does everyone else think?

The Thermal Margin is AMD's variation of CPU's temperature until outside its operational limit, right? So you haven't tapped the chip out until it hits 0, technically... granted, I wouldn't like to be more than 10 or 15. Nor do I think you can hit a high enough OC on the cpu to warrant going down to that, seems to me like the chip has some headroom in the thermal margin, maybe for a revision? But I could be wrong--this is just from my own testing...

You are right, I give you that. I just thought that there is a thermal margin I shouldn't go past. I know that on my older 2500K I needed to stay under 72"C package and under 100"C on cores.
I was able to push it at 4.7Ghz at 1.57volts but the thermal margin under prime was ~9"C and the heat coming from the top fans of my case was noticeable! mad.gif

Eek, I cringe at the single digit margins...must be the wussy in me! 4.7 at 1.57...that 1.57 scares me, but good to see some non-review 4.5ghz+. Not sure how high I can bump mine up to be frank--until I can get really on-point monitoring going on of temperatures, although my concerns with this being an mATX board haven't really materialized...it seems pretty well made.

My thermal margin never drops below 60 on my "always on" configuration, which is 4.3ghz @ 1.38v and 2400mhz @ 1.67(1.65)v... probably since I have 4 140mm fans and an H60 in push/pull with two SP120's on this APU...haha...or I'm just misinformed or getting the wrong read-outs.

Found it and read it, really great thread. I'm still trying to parse through specific posts to find out how they went about enabling it, what port was used, etc.--but definitely reassuring to have read it. Only wish it wasn't 2x the length of this thread... biggrin.gif Thanks for the heads up!

I have 6 x 120 mm fans on the case (Corsair AF120 @ 50 CFM each, 3 in , 3 out) and my cooler, a Thermalright TRUE Spirit has 2 x 120mm Noctua PWM fans on it. And the only way I can keep my cpu above 60 thermal margin it's to downclock it at 2Ghz with ~0.7volts (from Overdrive but at reboot it will still be 1.275v). In daily use it will never drop under 55 thermal margin and that's fine for me. thumb.gif

Check your PMs, I've elaborated on what I'm about to say, but I can't seem to get the 260x to show up simultaneously with the R7 iGPU in CCC. Is the XDMA use not through this? I've done as much as I feel as I can intuitively figure out on my Gigabyte F2A88XM-D3H. Plugging in the display into the GPU vs the mobo port switches the display.

I have no idea what I'm doing wrong, but I really want to see what the iGPU can do here, particularly if I can OC it further than it normally could without the combo.

Hmm... my 4 are AF140s. If it works well enough for you, it works, but I feel like you should be getting 60 thermal margin at stock with the proper cooling configuration, let alone having to downclock... but maybe I'm underestimating the H60 here or I just got a decent chip.

That and I notice that with the iGPU disabled temps are about 5c lower . Im at 4.2 1.35v on a CM 120V with one fan.

For monitoring I would like some realtime values of the NB voltage.

Firstly, I will ask you to read the other forum, as it states that while it works in some programs, there is no official support through DG yet. The power of XDMA is in the communication of APU/dGPU through the PCI lanes. Try AIDA 64, it will show you that it is working.
