GTX 485m users: need some infos and advices. Thanks!

Dear fellow users,
ive posted a similar thread in gaming section but i didnt received much response.
So ill keep this brief: a friend asked me to get a laptop in a certain budget range, the best deal was a clevo p150hm,2720qm,8gb and a gtx485m 2gb.
Actually we're waiting for the laptop to ship, in the meanwhile, we want to know some additional infos about the gtx485m.
I see that alot of users here have it, so maybe ill get a better luck this time.
Heres the questions, please reply as you wish, you can go deep in details or post reference links if needed:

- How much is the "standard" overclock limit of this card, without overvolt? As an example, generally my gtx460m can overclock on stock 800/1600/1500. This can be achieved on 98% of the cards around in various configurations. What is the "general" maximum overclock of this card?

- So basically between the 485m and 580m the only difference is the clockspeed, much like it happened with 560m and 460m?

- What are the reasonable temps in a P150HM when overclocked?

- How we can overvolt the card? I saw some bios edits, im fine with hexediting it, i want to know some directions, or better yet, a clevo overvolted vbios to flash.

Thanks to all the fellow users who want to reply to this thread in advance.
Looking forward to it!

 

Overclocking is definitely possible, but it can void your warranty. Over/undervolting definitely will. That said, if you still want to try it out, people have had luck overclocking the 485m to 580m clocks:

The difference between the 460/560 and 485/580m is not just clockspeed. The 485m is based on the GF104 core while the 580m is the GF114 core. The die shrink allowed for the 580m to run at higher clocks within the same thermal envelope. These links may help explain it better:

There isn't a lot of room for overclocking temp wise. You'll want to keep temperatures less than 90C, where full load temps on the 485m at stock can already be 75-85C depending on ambient temps.

 

Thanks alot, very helpful, specially that thread, i didnt even noticed it.
That answer most of the questions i stated
