I believe HWinfo also shows individual power usage by component but I always take software reporting with a grain of salt.

I read up on it a bit now and it's no problem to use one cable with double connectors with my psu. And it has been working for me for a week now so...

Hello, registered here to ask a question that's been bugging me for some time now.

I've got a MSI Gaming 6g 980 TI in december, and I've been struggling with it's temps.
Some info first: Asic 74.8; using an old P8Z68-v pro/gen3 motherboard that has only one 3.0 x16 slot, and even this '3.0' works in a very strange way, according to many people who tried using new cards on that mobo. Also, maybe this info is important: using a 120hz monitor and not using VSync anywhere.

Anyway, everything I'll describe below was attempted both in the first (3.0 x16) slot and the second (2.0 x8) one. The FPS results between those two options were completely, absolutely the same - not even a 1FPS difference was spotted by me.

I've tried playing with 100-109 Power Limit; going to +30mv at most; and +100 core / +250 mem (that would put me at ~1467-1480 mhz depending on what's happening in game).

The vast majority of games play at ~72-74 degrees on max settings; in case some game has a slightly... suboptimal thing that puts GPU at instant 100% load (for example, in Diablo 3, if you don't limit the framerate to 200, you reach astronomical ~800 FPS on the lobby screen), my card slowly but steadily goes up to 83-85 degrees where it starts throttling.

I have a rather good air-cooling case - HAF 932. I've tried using a really strong side 200mm fan, even a 120mm fan at the bottom of the case (getting the air in, just like the side fan) - those things don't really help.

The most brutal thing, however, is World of Warcraft. If I use the Nvidia MFSAA settings suggested by GeForce Experience (not using the DSR settings), I get almost instant 82+ in any large zone. Even if I use some other AA setting, it still hovers around 78-84.
I've tried playing with the fan curve, but it doesn't really matter because I see such numbers even when I test it with constant 100% fan speed.

Is something wrong with my card? In my country MSI doesn't provide any service for videocards - I'll have to speak with the retailer, and unfortunately the retailer I purchased this card from is known for being incredibly customer-unfriendly, so I don't really want to go there unless I'm 100% certain the card needs replacement.
Hi, I too had cooling issues on my evga gtx980ti sc+acx 2.0+ and with a decent air cooled case (TT Core V71) being a really hot summer here temps were hitting 70-85c causing throttling, I don't know how you feel about spending more money but I bought a Kraken G10 and a cheap Corsair H55 AIO unit and now my temps are around 42-52c gaming load and thats with an ambient room temp of 25c+, if your keen loads of info here http://www.overclock.net/t/1487012/official-nzxt-kraken-g10-owners-club

I read up on it a bit now and it's no problem to use one cable with double connectors with my psu. And it has been working for me for a week now so...

Mine works with one cable as well like that but the point is that with a modified power table in the bios it increases power draw which can either cause the cables/plugs to get hotter because of the increased current draw or the card will not pull as much power as possible and it will power throttle which would decrease performance. My PSU is capable of 70 amps on the 12v rail but that doesn't mean that the total of that can be drawn from just one cable. That's the total available across all connectors using that rail.

For example, if I run heavensward benchmark with only a single cable it will complete the test but monitoring the power draw will only show that the card is only capable of pulling ~50% of power that it needs but with two individual cables it is able to pull 100%+. A single cable is fine with a stock bios but I wouldn't use a single cable with a modified bios. You won't be able to use the card to 100% of its available performance or you could damage the cables or connectors through excessive current draw.

Sadly, it's pretty much non-existant in my country, and getting anything shipped here is also a problem... Still, thanks for the advice, I'll keep it as a last-resort-ebay-option.

There was another question, completely detached from my previous posts... When I play some games, especially Diablo 3, I notice random HEAVY drops of core frequency. Like, it may be going at 1467 for several minutes, but then, during some heavy load in a public 4-man game, I get a small 'stuttering' and then my overlay shows ~1149-1240 mhz for several seconds, before going back to 1467. When I check the graphs to see what was happening during those seconds, I notice the sudden and heavy drop of voltage (~0.2 - from 1.2xx to 1.0xx).

What could be the cause of this? Bad PSU? Some Windows problems? Non-optimal vBios?

could very well be GPU boost 2.

the 1.0v would be the "stock" or non boost voltage whereas the 1.2v would be boost voltage. change the power setting in NV control panel from adaptive to maximum and see if that straightens it out.

Unfortunately, not the case - already have it set (and also set for Diablo 3 executable instead of 'use global settings' - to make sure).

Actually, it's very strange. Here's the whole deal (didn't take the screenshot and not at the computer any longer for several hours...):

- Temps are hovering around 60 degrees - this game, unlike WoW, doesn't really heat the GPU
- No stability issues at 1505mhz (!) with my card - @1.230v
- When playing solo, everything's totally fine
- The game never goes above ~60% GPU load
- Suddenly, when you're getting into a really huge mess of things happening at one on the screen, you get a micro-stutter and see your overlay go from '1505@1.230' to '1240/1139 @ 1.012'.
- I'll just repeat what I said earlier: during the exact moment when that 'mess on the screen' happens, the GPU load is not even close to high (60% at most), gpu-z/MSI AB show 'Utilization limit' as '1', and the temperature is also absolutely safe, very far from reaching throttling limits.

Other games don't have such huge drops for me. Games like GTA, WoW and others (even benchmarks) DO drop ~14mhz from time to time, but never do they go so low.
Then again it's strange why the driver decides to drop voltage/frequency, even though I have 'max performance' set and also 'force constant voltage' in MSI AB...

there ya go. it will want to drop back down to "stock" to save energy. as much as gpu boost increases clocks/voltage when under heavy load (within limitations) it will want to lower clocks/voltage from boost under a lighter load.

the only way i know to force it to your boost clock under all loads is to use kboost in PX.

E:
strike that part - you could also mod the bios to keep the voltage constant.

Ummm, ok. Not sure then what it could be.

Got my 980 Ti Hybrids running at 1467Mhz Core and 8Ghz memory using 1.23v each. Stable running pretty much all the new titles. Looking forward to Far Cry Primal, Division and DooM. I should be able to max out all these games at 1440p except for maybe DooM. Early benches aren't looking good.... Might need to upgrade to the 1080 Ti later this year.

I guess I could try with 2 separate cables and see if it is any difference for me.
