HIS ICE Q X 7850 Crossfire Benches

[Twirlywoos]

As benches get lost due to the size of the 7850 overclock thread, I'd thought I'd post my results here. Both cards are flashed to the Asus Bios.

Same settings as above. Strike at Karkand 64 Player Server.

**Note: I don't know what the hell is going on with BF3 recently because a few weeks ago I could hit 101 FPS. Since I am not the only one who has noticed this, it's safe to say that the card can reach 100 FPS in BF3 Multiplayer when the servers are running well.**

Updated OP. The latest 12.6 and 12.7 do improve things by 5FPS but they are very unstable (random game and desktop crashes) when I tried them last so I stick with 12.4

are you using asus or his bios? and does one card turn off at idle? to save power ect

Both cards are flashed with the Asus bios. I have no idea if one card disables itself in 2D mode sorry - if you know how I can check then I'll let you know.

But what I find strange is that even though I set the voltages at 1170, when in 3D mode the voltages increase to 1210

 

[wazza300]

using asus gpu tweak to set your voltages?

No, I use Sapphire Trixx. Here are my seetings, I just ticked everything lol

 

[wazza300]

you might fair better with asus tweak,see if voltages jump to 1.210v

 

[Twirlywoos]

I can't remember exactly why I stopped using Asus GPU Tweek. But I just checked my download folder and I had version 2083. It seems that there have been newer versions since, so I'll give the latest 2171 a try.

 

[wazza300]

its still a great oc @ 1.210v,your lucky to get two cards with high asic,would be good if you could manage to lower voltages though

 

[Twirlywoos]

updated op with 3d mark score

@Wazza I think it's because I have flashed the bios which means that it maybe locked to those voltages at default. But the temps are pretty good which doesn't bother me much. If there is another bios which people recommend then I'll re-flash the cards to lower the voltages in 3d mode.

I'm more interested in your Corsair H60 if you don't mind the quick diversion

I remember seeing that on Hexus when it was launched, I've always thought water cooling was more hassle than it's worth but a simple all in one like this really appeals to me. Did you replace the fans as the stock ones were a bit noisy or for better performance?

OP mate, but what case is that please, looks like an absolute beast?

Yeah, I was also looking at the fan controller, it's been a long day

Thanks for the benchmarks.

How about playing a level of 48-64 man gulf of oman on battlefield 3 multiplayer? The single player campaign is not very taxing.

64 player strike at karkand is in the results too.

Both, for better cooling and the sycthe's make a hell of a lot less noise than the stock fans. I was going to replace it with the OCUK stock range of coolers last month when it was £46 as it had a thicker radiator but after looking at some user's temps I decided to keep my H60 as there was no difference in temps.

Are those gentle typhoon ap-15 fans on your h60? I'm only asking because I've ordered one for my wanted 620 that is on my GPU. My current fan clicks when I lower the voltage on the fan controller but these gentle typhoons don't apparently (I hope)
