How to overclock a 7850 past 1050MHz?

Calling 1150 a moderate oc might seem a little over the top but that actually seems to be doable for all the cards in this thread. Havent had much time for benching games though, might give it a go in the upcoming days.

Oh and regarding the DC2 cooler, i was being a little unfair. Out of the box at stock settings it stays really quiet at load. Can't expect to maintain that at the clocks were heading for...
 
You could just put a new fan curve in and lower the rpm as long as temps are OK.
 
HeX, i just did another heaven run matching your settings (900/1200 instead of 870/1210) and scored 1258 points. The scaling is insane as it seems... :)

NVM, rerun again at 870/1210 and hit 12XX...must have been something wrong with my first stock run

I'm looking at getting the Asus HD7850 DC2 towards the end of this month but I've read conflicting details regarding the cards length, please can you tell me how long the card is including the overhang from the cooler?
I have an Antec 300 case that will only support a graphics card up to 11", according to Asus this card is 10.2" but I've also read that it's 11.8"!
If you could let me know how long it is that would be great!
Thanks for your help,

from all the posts in this thread i gather the 7850 runs incredibly cool even if overclocked at what seems to be running well for a lot of people at 1200@5800. My question concerns when do you expect to hurt the card. I would guess as long as it is not running aboth 90c 24/7 nothing can happen right? Can you acutally hurt the card when raising the voltage and overclocking without experiencing dramatic heat increases? Put another way, is only heat damaging a graphicscard or can it go bad at high voltage without heat issues?

These cards are designed to run at around 80c-90c max temps as "Hex" says. Its the impression that ppl have that lower temps means better overclocks and longer life. To some degree this true, but even if you lower the temps by a lot, (since I installed a Gelid twin fan cooler on my 7850, I never see temps over 45c in ANY application, but my overclocks remain the same). The main problem is overvolting too much and atm theres no definitive max safe voltage for these cards yet, only time will tell, but going by what other ati cards are overvolting to and their owners having had their cards at these values, 5850/5870, etc you can extrapolate (great word that) that 1.2v is a generally acceptable setting for 24/7 useage.
Also bear in mid this voltage will only be applied when gaming and benching, etc, as when idling in desktop, etc, its only gonna be using a lot lower voltage, somewhere around 0.9 volts I think.
 
I knnow it's been discussed already but in my case, to go from 1100 core to 1200 core requires 0.06 volt increase, and even though that still only takes it to a very 'safe' 1.155, is it worth it keeping it 24/7?

HeX did already mention that 1200 is very worth it for BF3, which I play, but I was after opinions on if the extra 100 for .06 volts is worth it?

absolutely worth it. you wont notice the extra heat/noise so why the hell wouldnt you want the free 100mhz?

Overvolting will not really affect the card due to the cards throttling when you hit a certain TDP.

Keep temps under control and the card will look after itself, but even then you can't really damage anything at high temps as it will automatically throttle.... AMD and NV introduced this tech to stop people from burning their cards out running stuff like Furmark at too high settings and sending them back for RMA.

Now if a card burns itself its due to a flaw on the actual card the the protection circuits couldn't stop.

Thank you guys, i was lucky enought to find this forum, and it was clear for me I had to buy this card for my first new pc desktop.
Here its my contribution. From a newbie.
