technically that is not true i would agree it would not be advisable to RAID, but you can RAID using esata.

 

I hope you know that when you run no battery the GPU is locked at minimum speed, for battery life. So you don't need to test anything special, just be in the OS itself. I really don't think you will notice any increase of battery life, unless the drivers puts the GPU a few MHz slower than the 185 drivers.

 

I knew someone will say that, while I was typing my replay
Yes, if you want it *CAN* be done, but that would just be lame. And if that connector unplugs, or you forget to plug it when the system turns on, then....

This is exactly what happens (without the music and image).

 

Hi guys,

To anyone who has the P9600 + nVidia configuration: what are your operating temperatures? And subjectively, would you say it's comfortably/uncomfortably cool/warm when held on the lap? What about the palm rest area, can you keep your hands on it for an extended period of time?

Thanks!

 

I have the 9600+nVidia and the subjective temps are fine. I don't beat it up with games and I haven't run massive simulations on it yet, but for general use the external temps are fine.

 

I don't have the P9600, but I do have the Nvidia GPU and do overclock it (see signature on OC guide on my speeds) when playing games.
And there is no problem. The metal base (Nvidia GPU only) is used as a heatsink so it will eventually feel warmer after playing games with a overclocked GPU. But the palm rest and keyboard is at worst light warm.

Nvidia GPU on battery or idle is at minimum speed, so the GPU won't be an issue. The CPU will do the same if you set the system power management to Power Saver and when you are on battery.

During normal operation (not gaming nor have teh GPU overclocked), meaning using the laptop as a desktop computer doing regular programing, web page design, recording, typing text/notes, watching videos (including HD movies), the laptop is cool (a little warmer then room temperature), in my opinion.

Note that on battery mode the fan never kicks in (but again I don't' have the P9600).

 

plus raid 5 is not a 5 disk raid, it is done using 3 or more disks.

 

For optimal setup, it's a 4 or 5 disk setup. I think the setup is called RAID 5+0 and RAID 5+1, but I am not sure.
4 disk setup: http://upload.wikimedia.org/wikipedia/commons/6/64/RAID_5.svg

 

Raid 5 is at least 3 disks with a parity bit split between the 3 of them, which is why it is slower than a raid 0 or raid 10 setup. Raid 5+0 is done using at least 6 disks as is raid 5+1, the only difference being if the raid 5 sets are striped or mirrored. I myself prefer raid 10 for most arrays, and raid 6 for file servers (uses 2 disks for parity instead of just 1 like raid 5)

a long, but worthy read:

Alright then! I stand corrected
