you are beyond help.
moron.

first of all, try disconnecting all other SATA drives, and also try another motherboard or sata card.
Mine is also a UST0 model and it worked fine, using an ULI chipset.

It makes no sense to "prepare" for the fall update. you can flash the beta of the update right over the very first dash version with no issues.
More likely, it is a bug fix for some problem they found, or some sort of security update.

open the patched firmware in fwtoolbox and check if the key it shows matches the key of your working original. there is no drive for which it doesn't work (except the new LG, but that can't be read/flashed at all so far).

the ram is both on top and the bottom of the MB, the four square chips on each side. It doesn't overheat unless it's damaged or the soldering is damaged.

and why exactly would cooling the CPU better cool down the RAM then?

uhm.. there's already a large thread on this, from several days ago.

if the bios is corrupt, then the console is lost. if you never tried to flash the console, then it's very unlikely that the bios is corrupt or defective.

It's not overheating. never has. in fact, it runs cooler than the older boards.

ANY kind of live hacks are not tolerated here.

It can also be a bad/defective/corrupt bios.

You already made a topic on this.
Just how much thermal paste did you put on it?

I don't see why it wouldn't work.

I don't like the looks of it so much yet, although it doesn't seem to be any less comfortable to use. If themes are possible with this dash eventually, that'd help the looks. The avatar stuff is missing completely in this beta, but the HDD install is well worth it, yes.. MUCH quieter since the drive no longe runs, and faster load times to boot.

latest toolbox version.

if you don't know what people are talking about, start reading till you do. noone will spoonfeed you the most basic information over and over.

would you stop commenting on week old postings without even reading what is being said? it's a devkit, there's no damn mod there.

the hdd security and memcard security are as different as can be. there's nothing similar about them.

the other "M" drives are just different firmware versions, but the same drive.
the benq is fine, just remember to get the key from your old drive before you replace it.

c4e doesn't usually mess with chips, but firmware flash. although it might require an addon chip for an external firmware if the internal one really isn't flashable, though.
