UPDATE:  I think if Microsoft does increase the RAM - it would have been something they were considering the whole time.

               Also - I have surprised by how many people have gotten banned or modded on this thread.  I love passion - but please keep yourself in check and   remember to be respectful to others - regardless to how clueless you think they are.

-------------------

Note: If true this would give developers 9GB of RAM for games for the Xbox One.  They did the same thing last time, doubling the RAM of the Xbox 360 to 512mb shortly before launch.

As rumors are continually made about a change in the final specs on the Xbox One we have now heard rumors from a member on the website Beyond3D that Microsoft is actually asking developers about an increased GPU upclock and a increase in total DDR3 RAM to 12GB.

    “Plus, I did say it was a rumour so neither the upclock or RAM increase are confirmed.

    And it’s not just that the veracity of the rumour isn’t confirmed, but that the rumour itself does not claim MS are definitely increasing the clocks or RAM.

    Apparently, the story apparently is that MS has gone to devs for feedback on a few different things, two of them being an increased GPU clock and an increase to 12 GB of RAM (another thing on the list was storage for ‘tombstoning’ - I’m guessing flash cache)

    Devs have to list which spec changes they prefer in order of importance. So nothing is confirmed as of yet, just options MS is getting feedback on.

    However, I do have someone else telling me (also from a dev source) that we shouldn’t be surprised to see 12GB of RAM in the final box and that it isn’t as hard for MS to do as we think.”

This is not the only rumblings that the final hardware specs are still up in the air for the Xbox One apparently Engadget was able to get a inside look at Xbox One development a few days before the Xbox reveal which is around the same time beta devkits were sent out.  In the picture above you'll notice many variations of hardware design leading to the idea that these might also contain different variations on internals that are still being tested even days before the reveal.

    “The chamber is full of hundreds of variations of prototype Xbox hardware — today, it’s set to very cold — and is vital in determining how the Xbox One stands up to extreme thermal conditions. With laughs all around, he’s freed from the icy, zebra-filled prison. Surprising no one, the various beta kits of the console itself, the controller and the new Kinect all sport zebra-pattern tape to hide their shape (as rumored).”

It is all still speculation but the fact that we are getting information from good sources that the final specs of this device are still up in the air is a good sign that we still know little about what will ultimatley end up being inside our Xbox One's at launch.

As of right now current Xbox One devkits are running with 12 GB of RAM and the reason for the idea behind a upclock is that the Xbox One is running cooler or using less power than was planned and they can now allow for a stable upclock.  This is only speculation on why this rumor could end up being true and backing up what the insider sources have said, as a reminder the Xbox 360 originally was being built with 256 MB of RAM but late in the development Microsoft decided to use the 512 MB of RAM from devkits.

If so, will it effect your decision about purchasing the Xbox One or which one you will get at launch?

Wouldn't they have to delay the console? Or wouldn't that make it more expensive?

That's it! PS4 pre order cancelled!

Adding more Ram yes, that would drive up costs.
Increasing the GPU clocks, no.

Microsoft would have a fair idea how much headroom they can have with the GPU clocks, heck, I'm yet to meet a GCN GPU on the PC that couldn't hit at-least 1ghz without the need to increase voltages. (And that would go a LONG way of eating up the 50% GPU advantage the PS4 has.)

For the GPU clocks though, all that would be needed is essentially a software update, which every console has to have anyway, provided they don't run into any cooling issues, which they shouldn't.

RAM however gets a little trickier. They might have spare spots on the motherboard for more memory chips, or they might go with higher density chips, either-way, if the console has already entered production, they will need extra hardware work done to it.
If it hasn't, it will be a trivial exercise.

Wasn't there a rumour like this a couple months back. I don't think it's going to happen.

Chances are ms would just eat the cost of the ram increase i cant see them increasing the price at all

This far out? Hmm. Not quite sure it will happen, but it's not impossible. The GPU clock increase would be very nice, but the increase in ram would be quite questionable and probably a waste.

By the time this console comes out they would have changed mostly everything about it. Good job MS.

Ram is pretty cheap.  It shouldn't be that expensive to add an extra 4 gigs of ram.  Didn't it already have 8 gb?

you can buy a 4gb ram card easy for sub $30 for a single consumer.  For a big company like Microsoft buying millions and putting them into a console, they would get a good deal or already have deals, ect.  I doubt it would even cost $10 extra per console.  

It went from the rumor of underclocking because of performance issues, to now overclocking..........
and while 12gig of ram would be great, both of these rumors wont come to pass. Wouldnt the Xbox one be well into the production phase by now?
