I think the windforce may be longer?

If the 7970 or 7950 GPU block screws are in a 53mm square like the 285 and 380 maybe one of those can be altered to fit also?
The distance from the GPU block screw (7870, 285, 380) to the bracket is 90mm. If it is the same those could be altered to fit also ?
I think the 380X is also the same ?


The upper heat sink is the 285 heat sink and the lower MSI 380 heat sink. A 6" rule (152mm) is on the 285 heat sink.

I think the reference coolers, like the one that PowerColor is using is longer, so in any case, it should be longer than any costum pcb cooler like the 285 or 380 from, the block gpu area appears to be the same, maybe it can fit...?

Anyone playing War Thunder on these cards and experiences cloud flickering?

Cheers!

I was the person who said that...

I don't know about the Fury X because I don't have one, I just said that the specs of 380X Crossfire and the Fury X are the same (4096 SP, 64 ROPs, 256 TMUs)

I also can't say anything about the 390X, also because I don't have one.

I can, however, provide benchmarks of a 290 vs 380X Crossfire. Keep in mind that the 390 is the same card as the 290, just with higher clock speed, and the 390 and 390X are within ~3% of each other. Also, my 290 was at 1200mhz which is faster than any factory OC 390 or 390X.

290 1200mhz: http://hwbot.org/submission/2677510_neurotix_3dmark___fire_strike_radeon_r9_290_12010_marks
380X Crossfire 1150mhz: http://hwbot.org/submission/3223945_neurotix_3dmark___fire_strike_2x_radeon_r9_380x_15316_marks

380X Crossfire Valley Extreme HD:





You can see that in Fire Strike, the 380X are quite a bit faster than a 290, in fact they are not far off from my 290 Crossfire setup (which got around 18k). In Valley, two 380X is only a little bit faster than a 290, but the main reason for this is that Valley runs quite poorly on AMD setups.

I would recommend a single 390 or 390X in a heartbeat for 1080p, single monitor setups, instead of two 380X. I'd even recommend it for 1440p instead of 380X Crossfire. Where I would recommend the dual 380X setup would be for something like Eyefinity or 4K on the cheap, where no single card will be adequate, but two high end cards (or a 1080/980ti) aren't an option due to budget.

That said, it would be foolish to get two 380X now that Polaris is coming at the same price point. The only reason I went with dual 380X is because 1) I had one 380X already and 2) I'm saving my money for dual Vega. Since I already had one, and I didn't want to wait for Polaris, and go through the hassle of selling my first 380X, I went ahead and got a second one instead. I play at 5760x1080 and one card isn't enough. Other than that, they are placeholders while I wait for Vega or big Pascal.

I intalled my first real game after installing the Sapphire Nitro 380X.

I installed GTA V.

When using VSync and medium-high settings it works mostly fine.

But as soon as I attempt to dial things up or disable vsync, the card throttles like there is no tomorrow... If I set power limit to +20% it throttles less, but still throttles.

Anyone know wazzup with that?

It is clear the card has some kind of issue that prevent it from actually working in the advertised speeds (when it is running at 600mhz or something like that it works fine...).

Someone know what is wrong with it?


Mind you, I am not talking about FPS dips, the average FPS stays quite high actually, I am talking about very visible stuttering (not "micro", I mean actually stuttering), menus in GTA that refuse to work properly (they stutter a bit and then freeze, and never finish displaying), and when I used RTSS+HWinfo64 to display some stats, I could see the GPU voltage and clock going all over the place, while the VRM output in watts never hit 100W (if there is +20% power limit, if I leave it stock then the VRM output is always below 75W).

Does it happen with other games?

GTAV is not exactly known for being the best coded game.

'Additional Settings' is now gone, Can't adjust color, or Custom res

Before


After


Then it opens up the stupid Windows display calibrate w ClearText



I might go back to the old Drivers, I always use DDU before updating drivers, and I install the 150MB/90MB apps

In the latest version of Crimson? Which tab will lead you to Preference?

I'm guessing I'm not the only one who absolutely loathes the new interface in the Crimson drivers, and how they try and hide and obscure everything.

Nothing was wrong with the driver layout before, at least you could access everything about the drivers on one freaking page. I can't for the life of me figure out how to totally disable Crossfire in the drivers on my setup. Like, not through a profile. mad.gif

In the start menu (press the home button if you're elewhere) you should see the Preferences at the bottom.
