Open... and close... and open...


I remember having to slightly bump the voltage on my PCs ram to keep it running full speed with the suggested timings. (This was high speed gaming ram)

From catching up on the 4G thread, it looks like the team is closing in on the problem, and have had some success at 1.35V but with strange timings.
 
Magnesium is 1.05J/gK
The idea of a magnesium heat sink made me smile. :) This would provide us with the spectacle of a Pyra in flames! Nicely thematic, but Pyras are rather pricey for a one-time entertainment use, however spectacular the effect. :p

Well...As far as I can tell (most of the chat about this is a little over my head), while it works, it currently doesnt work "as it should". Setting the voltage over the spec to make it works is not ideal (battery life, thermal...).
The good configuration is still beeing researched. It's reassuring that I've never seen talk about hardware fault, so there's no talk about a new bord revision because of this, it's just some software (kernel) configuration to be found and applied at the right time. Others issues of the same genre are also being researched... I'm betting ED wait for all of this to settle ;)
Your reading of that list is more optimistic than mine! It seems to me that the cause(s) of the 4 GB problems has (have) not yet been identified. And that until the cause(s) has (have) been identified, it will not be known whether the solution(s) will require hardware changes, software changes, or just configuration changes. Of course, like everyone else, I think, I hope that the problem(s) will be tracked down soon and that that solution(s) will just be configuration changes; that could happen any day. :) This might be all completed before ever the plastic cases are mass produced!
 
Massive bloc of magnesium presents no risk... You'd be hard pressed to heat it hard enough for it to ignite... The rest of the pyra would be completely charred before the magnesium would burn...

Magnesium + water + high temperatures = you're gonna have a bad time. Anyone who's taken a basic chemistry class knows that.

And while, obviously, you've got bigger things to worry about if your Pyra gets wet, you definitely don't want some magnesium parts of it happening to go up in flames if that water happens to contact hot parts, or the water ITSELF happens to be hot. Being in the presence of steam is as good as "Please give me fire" when you've got magnesium around.
 
You are mixing with sodium, don't you? It definitely would not be used, for example, in cars if humidity was an issue, there's natural passivation occurring due to oxydation layer... Magnesium in powder is another story through...
 
I used to ignite pencil sharpeners in my younger years, fun! :D
How, what we're they? The little ones I had were plastic with a steel blade in them. (As if a sharpened pencil want enough of a weapon, we also had the pencil sharpener with something that was basically a thick razor blade in it. That, and the countless paper cuts I got tell me that the rules against having knives were kinda pointless.) I don't know what the wall mounted ones were, but I thought they were all steel.

I think I would like to try cutting a hole in the case and mounting a copper piece to help get some of the heat out if I can find a good enough spot. I think someone proposed doing that with the location being near the hinge above the keyboard, where fingers aren't likely to go, and it can still get air when placed on a table. That idea stuck with me. It seems the mockup that was shown with it covering the ports might lead to discomfort while holding, or maybe burns, if it works, and I plan on using some of those ports. Is anyone else considering trying to hack in one of those tiny fans if there is room? Maybe we can try combining these ideas.

I need to try to remember the Pyra is a small computer, not a car. Well, it does have flames on it. :p
 
Also, if fire is an issue for you, I'd way more concerned about the battery... To ignite a magnesium radiator, you would probably need to take a torch to it...

They look like this, the blade, the screw and some magnesium powder are the only things left after torturing it with a gas torch :D

Oh, I think I have seen some like that. Most of us just had the plastic ones, some with the compartment to hold the shavings. When I had the ones with that compartment they always opened or broke, sometimes getting shavings everywhere.

Anyway, modern day me would prefer one of those pencil sharpeners over the plastic ones. Unfortunately I now almost exclusively use 0.5mm mechanical pencils when not using a pen.
 
Hopefully all the posts about liquid cooling solutions for a DS sized handheld are meant in jest.

If this thing ends up getting a fan or liquid cooling, it's an insta refund for me. If even Microsoft can't figure out the fan in the surface without massive throttling/noise issues, then it's not getting figured out here, and it'll be one of the first things to fail. And then I have to start worrying about dust for a friggin handheld.

Let's just underclock the thing a bit if it's not possible to get it within whatever the tolerances are.

Magnesium is very light and strong, used in a lot of places such as Thinkpad laptop frame, and Helicopters to give two examples.
