post #10241 of 10371
I've waited for the pricedrop of the GTX 1080 and bought one two weeks ago (Asus Strix non oc version), but I have a question about the memory clocks.

I oc'ed mine to +225mhz on the core and +525mh on the memory. When I benchmark in unigine heaven I'm getting 11080MHz on the memory, but when playing GTA V or Titanfall 2, it downclocks the memory to 10080MHz. When I unload my overclock, the memory goes down to 9GHz when gaming.
Is this because not all bandwidth is used? I thought only the core downclocked when hitting temperature/power limits.

My GPU core nicely starts out at 2140mhz and stays between 2105-2025mhz when warmed up (67-69°C during full load, slighty lower when gaming with the fans on auto) so I think that's a nice OC, but I'm not sure about the memory.
When benching in Unigine Heaven, my points increase until I go past +525mhz om the memory. At +550mhz I'm getting the same score as on +525mhz and at +600mhz my score starts dropping, so I'm guessing +525mhz is the optimal point.

I went from 2600-2700 points to 3104 in Unigine Heaven after my OC (1920*1080, ultra, 8x AA with a stock i5 4960), so that's a pretty nice card imo. But I'm not sure why my memory downclocks with 1GHz while gaming.

After doing a bit of testing, it actually goes to 88 degrees.

I wonder if this would work: http://m.ebay.ca/itm/Water-Block-High-Pressure-Pump-For-GTX1080-1070-VGA-Card-GPU-For-Nvidia-ATI-/172568273486

Hello fellas, it's been a while.

I've been away from benching for a while... but the urge is catching up!

So since there isn't any bios editor for Pascal, I figured my best bet would be to try to flash the Asus Strix T4 bios onto my FE card.

I power modded the card with liquid metal. It's water chilled (Hailea HC-500A), so I can get water temps under 10C and bench around 2200-2215 fairly easily. But that 1.093V limit is annoying me...

Has there been reports of bricked FE's after flashing to the T4 bios? I haven't seen any, it seems to have a good success rate... (famous last words) biggrin.gif

Any last minute warnings? tongue.gif

Why there are 2 models of 1080GTX TI ? which one would I want to get ?

notice the ROPs/TMUs

Honestly, i wouldn't risk it, think about it this way your card was probably close to 500 dollars give or take right? Do you really feel safe cheaping out on something that if turned out to be junk would kill your card? I wouldnt even touch that, it has nothing to keep the memory or power delivery cool except a fan and that's not nearly enough. IMO go for full cover block or don't bother. 88C is perfectly fine for a blower style card i still have a GTX 580 that ran at 95C+ daily for 6 years.

I wouldn't actually use that smile.gif

I was considering either
1) hybrid setup, where I replace the heatsink with a 45mm waterblock

2) leave as is

3) remove side panel and replace with box fan (this way I keep mobo mosfets cool)

At this point I'm either going to go that route, or place a large box fan beside my computer (with the side door open)

I'm very wary of those. i have seen first hand too many times just what can happen if you do not cool VRM's properly especially on reference cards. I personally would never even give them a chance it's not worth the time or moneyif it died from VRM failure. With that said i am very very cautious with Power delivery cooling the primary driving force for me getting the ICX 1080 was so i could keep an eye on the VRM and Memory temps so take this with a grain of salt. Why not just crank up the GPU fans using MSI Afterburner if your really worried about the heat?

Holy crap that texture fill rate on the top one is nearly double what my 1080 does o.0

Does anyone know how to get that program to display the TDP of the vBIOS?

Hi,
I wanted to share my best overclock "Games + benchmarks stable" on my Gigabyte GTX 1080 Xtreme Gaming WATERFORCE 8G :

Core => 2228MHz
Memory => 11088MHz
Vddc = 1.181V


Bios => ASUS Strix OC t4 ( Version 86.04.17.00.76) => No more power limit, voltage manageable until 1,2V
+240MHz on core clock (Base clock at 1607MHz) and tweaking of the curve to have 2228MHz at 1.181V.
+595MHz on memory => 11088MHz memory frequency.
Fan speed of the AIO WC of the card set to 70%

Results :
- The card never dowclocks neither in games neither in benchmark => Stable core frequency at 2228MHz and stable memory frequency at 11088MHz
- Maximum core temperature around 53°C at 20°C ambient (Depending on the game)




Maximum bench core frequency 2253MHz at 1.2V !
Graphics score => 8629pts

You've really got that card tuned, my friend! Running 2228 solid is just nuts!
