Lately, I've received a number of faulty HP t620s. After combining parts, I've made a (very?) unbalanced HP t620. It is the dual core model, upgraded to 16Gb RAM... but sadly the it has a small 16Gb M2 SSD (and it doesn't seem to be a fast one). Also, I've upgraded it to the latest BIOS available.

So... it has two 8Gb RAM modules installed, but at POST it says that they're configured as single channel and the BIOS has no options to enable dual channel. Can it be enabled?

Also, I've completely wiped the SSD (it had a corporate OS) and I don't know what OS should I put in. My options:
- Using a Windows 7 x64. It would be a great option because I could use most games and applications (that run fine on that 1.6Ghz CPU) but that 16Gb SSD is very small and using USB as storage would be painful.
- Using Windows embedded. That thin client has licence for it, but I'm not sure how compatible is with standard apps. Although it would be smaller than Windows 7, the storage is still a concern.
- Using a standard Linux. Everything I usually use fit in that 16Gb disk, and I could use USB as data storage... but gaming from USB using wine would be still painful (OTOH, emulators would run fine).
- Trying that HP thing used on thin clients (thinpro?). My wife uses citrix to work from home, but I don't know if that OS needs a propietary server to connect as a client or can be configured like a standard citrix client (I've got a Fujitsu thin client that can't be configured directly to connect to any citrix without connecting to some Fujitsu software first).

Any thoughts?
