Elfear: Hm. Perhaps, but I wasn't under the impression that modern CPUs were all that much faster than somewhat older ones in games. Take, for example, this comparison between a Phenom II X4 955 and an i5 2500, which skipsneeky2 here says gives him 60+ FPS. Not a huge difference, is there? Of course, I don't know exactly how my particular CPU performs, as it's in a bit of a weird spot, but I can't imagine it's far below the 955.
skipsneeky2: That's more like the performance I was expecting. And yeah, Gulf of Oman is the most demanding.
And that definitely includes Battlefield 3, as I get a much lower framerate without the two extra cores unlocked.
I am having one problem with it. I tested my overclocks through Afterburner, but I went ahead and put them in CCC once I realized I'd be using stock voltage. The problem is that my voltage stays at 1.219v even in 2d mode. The speed drops to 400 MHz, but there's no decrease in voltage.
Any thoughts on this?
Well, it seems I got a "dud" of a 7870. The ASIC score is 71%, and the best quick OC was 1150/1390 at stock voltage . It seems to only like stock voltage (1.218v). At 1.25v, it's still not stable at 1200. At 1.168v it's not stable at 1100. These are the best overclocks, but I'm certainly not complaining.
I haven't actually played games with it yet, because I've been testing the stability during the RMA period. My Heaven score increased from 888 with my 4870 512MB to about 2300 at 1150/1390. That seems to track pretty well with AT Bench. The 7870 stock is supposed to be 2.3 times faster than the 4870, and my OC increases that to 2.6 times faster. Also, having 4 times as much memory is a nice feeling.

update your bios...
I ran into issues at one point being stable at even 1100/1450 using msi afterburner @ 1.21v,my stock voltage.I replaced that program with asus tweak,enabled 1.225v and my highest overclock currently is 1150/1450 and its perfectly stable using 12.9 beta.
I doubt theres not a single card that can't do at least 1150/1450 at 1.225v,most people are running 1200 core at this voltage,seems 1150/1450 is the norm for 1.225v from my readings.
why use 1450mhz for the memory? not even in synthetic benchmarks does it make a difference from 1375 to 1450 or higher, I tested 1500mhz and my score didn't increase in luxmark or 3dmark11.
Mine is MSI twin frozr III R7850 OC
I managed to do 1050/1375 at 1.038v (stock voltage OC) 1150/1375 at 1.110v, 1200/1375 at 1.150v and 1250/1375 at 1.2, I didn't attempt more since i have no idea what a healthy voltage is for my 7850.
My 7850 has 1.038v stock voltage, I see that most of you here have voltages of like 1.225v and 1.25v but you also have quite high stock voltages, like 1.1v+ and I only have 1.038 stock. Any experts on electronics here? here's a pic of my card's PCB, do you think it can take higher voltages easily?

I see that it has 2 slots for the power connector thingy, only 1 contains a power connector and since 7870 has 2 that must mean they used the same PCB, does that mean my gpu can take 7870 voltages? I've seen 7870s with volts of 1.3v+ so I guess that would be good to know if its true. But then again, I see that it has some missing parts, capacitors, resistors and whatever, only "drawings" where they should be, most likely some missing parts in the power phase area since I know that those little parallel chips are responsible for power phases.
Well this card is actually pretty good at 1080p, the only game that runs at "low" fps is bf3, sometimes fps drops to 40 in big maps when everything is maxed out including AA but most of the time it sits at 60+, In low player maps it's obviously more stable. I would get a card like your new 670 as well if I could figure out what foreign seller could ship to my country without added VAT or outrageous transport costs I'd sell my gpu and get that since that gpu most likely costs less than my gpu did.My card has been the odd duck model,my card refuses to be stable at even 1180 core with even stock memory clockspeeds,keep in mind we got the same exact card.
1150/1450 offers perfect stability in my case,but the remedy for a crappy overclocker is gonna be the purchase of a gtx670 in a few weeks time,most likely the zotac amp edition.
Been gaming at 1280x1024 but moving on back over to 1080p hence the upgrade.
I'm having zero luck unlocking the voltage on my HIS 7850. Any ideas?
Which one did you get? I have this one on the way this week:
http://www.newegg.com/Product/Produc...-pla-_-NA-_-NA
At least one review specifically says the voltage unlocks and I didn't see any cons that it didn't listed. I'll post if I have any trouble with it or not.
That's the one I bought, voltage does not unlock.
What have you tried? I'm a little concerned now.
Edit: Have you tried this?

That actually looks like a nice OC utility.
I've tried iTurbo, Trixx, and whatever Asus names theirs. The Asus came closest, it said it would only unload voltage on Asus cards.
