ill try to get to 1250mhz but dont know if it will do it.

Still around 600 points lower than me, and im only 13mhz higher in core clock than you. You pretty much supported what I already said tongue.gif.

Considering "upgrading" from a 570 to a 7850.... I got my 570 for a pretty low price so price casualties won't be high thumb.gif

Whats the stock voltage on 7850s, and is a 50% overclock probable (1290mhz)? What approximate voltage would be needed for a 50% OC? What is a good 24/7 voltage?

I've been eyeing this XFX 7850 for a few days... to be honest the short 7850 reference PCB sort of hurts my eyes... anyone got any XFX input?
I've owned a total of 7 cards; one Sapphire, two HIS, two MSI, two EVGA. Is XFX serial based warranty? Lifetime, correct?

Just purchased the Sapphire OC Edition 7850 for $243 shipped.

There's a -$20 coupon on slickdeals for it.

If you are seeing 1.168 at idle then it is nothing to be concerned about. At 2d or idle the card automatically ramps down to something like 300/500 (can't remember off the top of my head) and uses less voltage for power efficiency . However if you are seeing this voltage at full load in a 3d environment this might be something to look into. In a full load 3d environment the clock speeds will increase to whatever you have selected and voltage will increase to accommodate the rise in clock speeds. If your card is under full load at this voltage and not causing any hard locks or driver crashes then don't worry about it. If this is your MAX voltage under load you should definitely Overclock that card at 1.3 V and see what you can get out of it.

Voltage and overclocks are available by either looking at the first page or scrolling through this thread.

As far as the warranty on XFX goes it is indeed a lifetime serial based registration warranty. XFX provides either email or live telephone support customer service and their tech support even helped me when questioning large voltage spikes on my overvolted card.

As great as all that is I must warn you: When I run FurMark my card will reach +90 C within 2 minutes; whether this is common or an insufficient cooler I do not know. I am forced to end the benchmark / stability test at this point of fear of destroying the integrity of the card. Mind you this is at stock voltage and clocks. (XFX Double Dissipation Black Edition 7870)

Regardless, I am overclocked at 1300/1500 at 1.3 V with a MAX temp of 62 C (GPU-Z) in actual 100% load usage (BF3 64 player maps).

Obviously, actual usage is quite different from a test designed to break your card. Just watch your temps when stress testing and you will be fine.

Do you guys think Q6600 2.4 OC'ed to 3.2 is bottlenecking the 7850 OC?

I'm only really going to play D3 on 2560x1600 but will check out some other FPS games here and there.

:O Mine reaches like 76C in 15 minutes. 90C is just too much.

Interesting...

Guess I will be making yet another call to Tech support in the morning.

i would definitely call.

But it is odd if you're getting normal temps while gaming.

Here's a result of mine.

Which brands allow for voltage regulation on the 7850?
