I would not crossfire two of these cards. Because this is what that looks like:


That's from user magiccase who tried this in his Silverstone FT02 and gpu1 temps were too high. Granted that case is not ideal for the heatpipe orientation on this card. Otoh that case has the best airflow you're going to find, except maybe the FT04. Only way I'd even attempt crossfiring two of these cards is with a side fan, and not a big low rpm/pressure 200mm, but a high rpm/high pressure 140/120mm to blast the exhaust back into the heatsink so it doesn't get sucked up by gpu1 and to force cool air into that tiny little crack, better yet, a pair of lateral side mounted 140/120mms. Best of all would be a vertical expansion bracket above the pcie slots where you could mount one of these with triple 80/92mms:


If you have no side fan options just forget about it now. Even in an FT04, with this little spacing, any cool air that gets into that crack would be sucked in by gpu1's closest fan and the other two fans would just get exhaust from gpu2.

That's why I have a Tri-X btw, once I saw how thick this Powercolor is I ordered a Tri-X to use as gpu1. This is much more reasonable:


If you can't fit the Tri-X I don't know what your options are frankly. Asus DCUII has heatpipe issues because it's a GTX 780 cooler that's been hillbilly rigged onto the Hawaii die. MSI Gaming fans are too low rpm to use as gpu1, I have a friend who tried, simply doesn't work. I don't know much about the Gigabyte but maybe that's your only option.

So again... The quality wouldn't actually change? (Compared to 1440p)

As far as I know, no.
Sorry for not being clear.

got my Qnix qx2710 today and just got it hooked up about a hour ago, so far so good, no dead or stuck pixels and the blacklight bleed isn't bad at all! I got mine to overclock to 96hz but when I went to 120 I got some artifacts (using cable that came with monitor)

There *is* a quality difference between "virtual 4K" on a 1440p screen and 1440p on the same screen. The effect is the same as "super-sampling anti-aliasing", where a higher resolution is rendered, and then adjacent pixels are sampled down ("downsampled") to create a smoother-looking picture. It's basically a fractional super-sampling, which is inferior to integer (whole multiples, ie going 4x 2560x1440) but it still results in less aliasing/jaggies. The trade-off is slight softening of the image due to the nature of fractional super-sampling.

Of course, this only really works on 3D rendered objects. For things like text, fixed-size images (rasterized, jpeg, photos) there's no benefit and a slightly penalty.

Well that doesn't sound very good lol. What I find with my qnix 1440p is that at this res I don't really need anti aliasing. It's now the first thing I lower/turn off in game settings to improve framerates.

What's the performance hit of running this virtual 4k supersampling?

I see - but if the monitor was a 1440p with virtual 4k - rather than a 4k - there's no down-sampling occurring - just "upscaling" or "virtually" creating a 4K image.
In other words, it isn't really a 4K display.

Correct me if I'm wrong though smile.gif
Learnt quite a bit today in the QNIX models etc biggrin.gif!

Hello. Please forgive me if this has been asked. I've seen some variations of my question being asked but I want to be sure before I try this.

So Dream-Seller did not include an adapter. Therefore, what are my options?

I see the brick has a plugin that resembles a PSU cord plugin. Would that work? I have 2 or 3 of those laying around. So what I'm proposing is taking the brick and the dc plugin that came with the monitor. Taking the dc plugin and putting it into the monitor per normal. Then taking an older PSU power cord I have laying around, plug it into the other end of the brick, and then plugging that into my power strip, wall, whatever.

Will this be ok?
If not can anyone tell me what kind of adapter I need to try and find to purchase?
Or just any other solutions. Thanks so much!

I would be tempted to contact the seller and tell them to send it to you, free.

EDIT:
By adapter you mean a PLUG adapter or do you mean a power brick / adapter?
post #15090 of 25893
Aye, the brick/adapter.

Monitor --> DC Plugin --> Brick --> Power Cord(adapter should go here) --> Wall

My problem is the Power Cord portion of that crude diagram. I should have received a free prong/outlet adapter to use the cord they included. But I didn't. So I'm looking for options to take out their Korean power cord and replace it with say one of my old PSU power cords, a power cord that plugs into a 22 inch Dell monitor, etc.

Thoughts? Thanks!
