So I'm running 2x1080 SLI, one was an EVGA SC, one was EVGA FE, both are on the SC bios (just duplicated and flashed to both cards for simplicity). I'm using the EK blocks with EK bridge, CPU is also on the loop (6600K, stock), and all three are cooled with just a single 280mm radiator with EK Vardar F2 fans. I haven't spent a ton of time pushing my clocks, but the cards are easily keeping below 55c on the GPUs (that's for the top GPU, the lower GPU stays about 5c cooler) while playing GTA 5 at 4K with almost everything on very high (the shadows and grass on ultra bring framerate from solid 60 to ~45, unacceptable). I usually run between 1950 and 2050mhz on the GPUs, and even when looping firestrike ultra, the cards don't go over 55c over a prolonged period of time. The fans kick up to their 1600rpm max with this, but it's fine, it's not that loud, and my setup isn't "optimized".

I thought I'd need much more radiator, but I'm pretty pleased at the performance I'm getting with just 280mm on CPU+2GPUs. The die shrink is real! Hopefully this helps people wondering how much radiator they need. I would recommend my setup at minimum, I wouldn't go smaller than 280/360mm for CPU+2GPUs, but I can see where CPU+GPU or just 2 GPUs you could get away with 240mm without much problem.

Thanks for the info, il keep that in mind.

Non oc bios @ 1900 attempts to boost to 2050-2060 on firestrike this crashes on the second gfx test
oc bios @ 1900 only boost's to 2010-2025 but runs firestrike bench without issues.

Both cards were near enough identical

So with oc bios Im actually reducing the clock by 36(MHz) compared to the OC profile on GPU Tweak and somehow the boost is less aggressive and gives me a more stable overclock
However you could take your chances and go for the non oc version you may get a better GPU than me.

So you basically paid 50€ for a Bios ?
I am pretty sure that the non OC, A8 and OC Versions are exactly the same Cards. The production would be way to expensive if they would make 3 Cards thumb.gif

It is just the Bios and when you dont have two left Hands you should be able to Flash the bios. Even rma a flashed Card is no Problem, I did it at least 2 times before thumb.gif

What about the non overclock strix versions? Worth spending 60 extra for higher clocks or OK to just flash the non OC version to OG bios?

What up?

No I bought the non oc version because there was a supply issue at the time and couldnt wait. I had a very expensive paper weight under my desk.

Both cards would not run stable at the 1936 clock speed the oc version is claimed to achieve using the OC profile. I agree the cards are probably exactly the same but the gpu's must be hand picked for the oc version.

I believe that the only explanation for those cards that have exactly the same construction but different names/clocks (Like MSI Armor/GamingX/GamingZ) is that they test each GPU and brand the best ones as the top/oc models.

If we have some Armors that can't handle GamingZ OC Mode (like mine), even though they are exactly the same hardware beneath the hetplate/backplate/cooler, that means something.

ahhh okay I got your Point thumb.gif
yes maybe that is the case but I dont know what they production Looks like.. I mean they gurantee a certain clock speed on all 3 Versions. Would I be the Boss and all my Chips would be able to hit the max. clocks ( OC Version ) i wouldnt even bother to select some "Special ones" for the OC Version...

But that is all pure speculation rolleyes.gif

Well after tweaking my MSI GTX 1080 FE since release day here is my final results for a full stable OC (game + benchmark) :

Graphic setup :
- 1440p , 144 Hz, GSYNC

Computer :
- i5 4670k at 4.2 Ghz
-16 Go RAM at 1600 MHz
- Motherboard Asus Z97-A BIOS 1503


My OC results:

Parameters :
+120% TDP
Temp max : 85°C

- Core +150 MHz giving a stabilized clock of 1949 Mhz at full load
- Memory + 425 MHz
- Temp at full load : ~ 80°C with custom fan curve (1%/1°C beyond 40 °C)
- Maxed monitored Vcore : ~ 1,06 V


I start having artifacts in games (in particular Witcher 3) with a +450 MHz on memory, which is a poor OC in comparison with some of your OC.
Core + 175 MHz will crash drivers in some games / benchmark. Example : 3 loops stable with Unigine heaven but crash with Unigine Valley at the exact same moment into the benchmark
Boosting Vcore doesn"t help the OC . I have the same result with +100% vcore (MSI afterburner).


I'm a little bit disappointed by those results as I wanted to reach 2GHz barrier but the gaming experience is amazing and I have no regrets in purchasing this card.
Coming from a GTX680 2Go the performance increase is absolutely incredible.

You're probably throttling a lot with those temps. If you adapt an AIO Watercooler you'll certainly get those 2ghz you want.

This must be the case, strix oc cards are like rocking house S*&t there is a waiting list as long as my arm. If they were exactly the same surely there wouldnt be a supply issue. Unless they are doing it deliberately to increase the price. They wouldn't do that would they:rolleyes:
