I haven't heard of any Clevo D900T's that couldn't overclock the GPU.
Well what you just said pretty much explains it doesn't it.
The 5720-V is pretty much a clone of the XPS 2/M170. Because of the inability to OC the 7800 Go GTX in the M170, it makes perfect sense why the 5720-V is having the same issues.
nVidia first released the card for the Dell XPS M170, therefore its highly likely that nVidia is allocating the same GPU's to CLEVO/SAGER as for the M170's. It appears all other models with the card are OC'able, this may because of less rigid operating spec limitations in these "Clone" systems. Remember, the M170 was designed as a high end luxory PC, nVidia modeled the card from that system.
I think what is happening is that in order to cut back on RMA's, Dell had nVidia lock the 7800 BIOS. nVidia then produced a ton of 7800's to Dell's specs, not just for Dell M170 systems, but for upgrades, replacements, etc... So the N produced a bunch of cards with a locked BIOS. Once the card lauched to other vendors, nVidia stopped locking the BIOS on those cards. So as a result, some folks are getting cards that were intended for the M170 and some folks are getting cards that were released after Dell's exclusive period ended...
