I think the best bet for a ram upgrade would be to replace the ram in the xbox with higher density chips/sticks and hope the firmware supports the upgrade.
Because odds are it's the OS reserve that is specified and not the ram the game uses.
I'm sure this console season will have unprecedented box modding due to the standardized nature of the hardware.

Did you actually read the articles? Because they completely contradict each other and any argument of 12 GB.

Both articles say that Dev Kits have 12GB of RAM. And, if true, that mean 12GB is (technically) feasible, not impossible at all .
EDIT: This is interesting (from the examiner article):

On most of these devices, clocks are based on some multiple of some base clock, selected in the firmware, or bios.
Depending on the device various components will have different clock domains. So the GPU clock may or may not be tied to the ESRAM clock or the CPU clock.

Someone correct me if I'm wrong but im pretty sure that clocks for at least any modern system are tied to some software (BIOS/firmware, etc) and not to physical hardware. I can imagine that dynamic clocking could actually be useful for them to a degree to keep sound and heat down in situations were games are not open.
Yes of course. It's the same as how you'd overclock your CPU on your PC. You go into the bios.
I think that's what the MS person meant, I guess they are somewhat correct but it's more like a firmware change. They are just simplifying for a mass audience and/or dont fully understand it themselves.
Of course a chip's clockspeed is not some sort of physical property of it as it rolls off the line...
Clocks can entirely be controlled by the OS layer if need be, the only elements that are set at the hardware level (which will be controlled by the PCB) is a default "boot" voltages and speeds which may not necessarily relate to any clocks that you would think of as running clocks.
Our discrete GPU's actually have a microcontroller on them with arbitration code that dictates what clock/voltage state it should be operating at dependant on a number of parameters - i.e. if the activity counters on the chip are high it will push to a high clock state for peak performance, or if the activity is low it will drop to a lower clock/voltage to save power; alternatively if it is calculating that the activity is hitting a power threshold then it will modulate between states to keep the power in check. The microcode to do this is loaded into the GPU from a table in the BIOS when the driver is loaded by the OS but those limits can further be controlled by software in the OS.
So when they are saying "the GPU is clocked higher" but also saying "we've not changed any hardware" these don't contradict each other; likelihood is that whatever part of the system dictated the max clock / voltage state of the GPU portion (be that firmware or OS) has just been updated.

There have been tools to access GPU clocks from within windows for nearly 15 years that I can recall, perhaps longer still?
Out of interest and totally unrelated to any console : is it possible to disable/enable CUs via software?
I'm not Dave but, you used to be able to buy a few GPU's and get more execution units out of them (they weren't CU's back then) by flashing them with certain Bioses IIRC. X800 was one back in the day...which would suggest it's possible.
Now I think they "laser cut" off any units they dont want you to use, so they're basically hardware blocked, on PC. But that's to prevent people gaming the system, not sure if they'd do that on a console.

You mean developers actually hacking the X1, pushing clock speeds without Microsoft's permission and possibly losing their license to develop for the platform? You really think they'd take a risk like that?
If anything that article represents yet another example of the kinds of sites that are covering gaming and gaming technology. This Adam Barnes doesn't seem to have a single clue of how upclocking on a modern system occurs. Hmmmm.

Well didn't Sony disable SPEs on the CELL?
Looks like AMD will unveil Hawaii/Volcanic Islands tech in late September, launch at Q4.

A little quote:
I'm posting this here because I'm wondering if it's possible Durango (or Orbis) are fully/partially based on new tech, not Bonaire nor Pitcairn, just like Xenon had Unified Shaders more than 6 month earlier the PC product was launched. At least better HSA integration or efficiency improvements?
At Q4, AMD 7970 will be 2 years old.

Not developers. Regular joe hacks who like to tinker with hardware or is it more likely that MS will lock that feature down in production?
I get the way in which CPU\GPU's are upclocked but there were a few people who were talking about hardware respins etc And this kind of knocks that on the head.
So there is this Xbox One unboxing video :
http://news.xbox.com/2013/08/xbox-one-unboxing
And Larry mentions nearly all HW specs (HDD size, CPU, Wifi) but does not talk about the RAM at all... Time to revive the 12GB rumor.

To be fair it doesn't actually knock those on the head.
The respins may have been what got the gpu to 800-853.
The setting it in 'software', just means that they could settle on the final clock speed once all the validation, TDP, yield results, etc had been taken into account.
