I am using pc wizard to get my voltages. Its dl at cpuz website.

Ok I have 3 gtx 280 xfx
1. temp 80C (not on full load)
2. temp 46c Not on full load
3. temp 52c not on full load.

What is the maxium temp for this graphics card I know 80c is pretty hot I t hink like 150f. Should I be worried atwhat might happened I dont want my card to explode or just break

Also I just got a new motherboard the evga 760. How do I tell if the cards are running at 16x 8x or 1x? I know it doesnt matter much but I really wanna know lol.

under cpuz it states

Card 1
Core 602
Shaders 1296
Memory 1107

Card 2
Core 300
Shaders 600
Memory 100

Card 3
Core 300
Shaders 600
Memory 100

With this info it leads me to believe that It is 16x 8x 8x but I wanna make sure.

Memory
They are 1g cards dxdiag states I have 4077MB of memory for Display 1 and 2
It isnt taking memory from the ram though because task manager states it has 12279 Total ram installed.
I have 6 2048sticks or 2g sticks installed

Recap
1. What should my 1st xfx gtx 280 temp be in a tri sli setup
2. What speeds are my pcie running at and can I change them to max amount
3. Why does dxdiag state I have 4077MB of memory for the display Under display 1 and 2

Since you're not idling (as noted by the fact that card 1's clock speeds are at load) then I wouldn't worry about those temperatures. Most high-end cards' fans don't even really ramp up until you hit 90C. Cooler is better of course, but you're well within spec.

You should run something (e.g. a game or FurMark) and then see where your temperatures end up. It's only under full load that you need to be concerned.

Ok I have an at load temp

1st card 105c
2nd card 43c
3rd card 51c.


105 is hot. I mean burn your hand if you touch hot lol So its that normal. I was playing batman arkah asylaum.

Seems to me SLI is not working if only the first cards temps are rising. (and 105C on just gaming seems to be very hot, i would turn up fan speeds if possible)

Check if SLI is enabled and if your cards are running x16 with GPU-Z
http://www.techpowerup.com/gpuz/

It lists x16/x8 etc under "Bus Interface" and lets you know SLI is enabled at the bottom.

Ok under nvidia control panel i have enabled both 3 way sli and physics. I assume 3 way sli would have to be working because thats what comes up in there. If it came up with 2 way or not at all then I think it wouldnt be working. lol my logic may not be sound though lol

Ok as for the graphics cards the speeds are

1. pci-e 2.0 x 16 @ 16 2.0
2. pci-e 2.0 x16 @ 8 2.0
3. pci-e 2.0 x 16 @ 8 2.0

So I figure its at 16x 8x and 8x

The one thing thats a bit odd in gpuz and please bare with me here.

When you go to the bottom to select the card you want the last one for me is the x 16 the first 2 are on the top. Now from what I am used to 1st card/fastest should be first in the list now this may mean nothing it may mean something just wanna throw it out there incase it can help

as for fan speed I have already turned all 3 up to max under nvidia control panel.

Just to be certain is there a way to check to see if all my cards are working in 3 sli function. I would hate to loose out on that benefit.

and something else in unusual. In the nvidia control panel the first two if you put it on automatic speed it goes straight to 40 percent the 3rd goes straight to 85% as if that one is running hotter then the other two.
So maybe my first two arnt running at full speed but my last is.


EDIT Scratch that after I placed my hand on the card the first one is def way hotter.

The south bridge is also placed down underneath the 3 graphics cards.

Ok, what you can do is open 3 instances of GPU-Z and go to the sensors tab (will show you temperature bar, fan speeds, and GPU load (whether the card is being used or not))

switch all the instances of GPU-Z to the sensors tab, but make sure every GPU-Z window is selecting a DIFFERENT video card. Also check the box that says something like "Keep GPU-Z refreshing while in the background"

run a quick game or graphics benchmark, alt tab and check to see if every card is being used and the temperatures

Ok for gpu load it has

1 87% temp 85
2. 29% temp 51
3. 15% Temp 53

Now that I look at it I think it may be running 16x 16x 8x

2 of them state
gpu core clock 602
gpu memory 1107
gpu shader clock 1296

1 states
core 300
memory 100
shader 600

It would stand to reason that the card that is running @ 2D speeds isn't being used...

I dont know anything about that just i figure if 16x for example gave

16 x gave 20
8 x gave 10

Then it would mean that the 8x should be half of what other card is.

also It did have a 15 percent gpu load. Doesnt that mean it is working?
Also it has mb used 800mb around. The other two cards were around 900

Now with that info given does that still mean the 3rd card isnt working or is it. Sorry if I didnt give enough info the first time

There is the temp the card needs to stay under for stability, there is a higher temp the card needs to stay under to prevent sudden failure, and there is a lower temp the card needs to stay under for good/long lifespan.

Your temps are at the very least, higher than this latter temperature range on the hottest card.

Install a fan in the case side panel directly across from the cards, blowing on them. If for some reason you cannot or will not cut a new hole for the fan if it is necessary, you could instead mount a bracket entirely internal to the case blowing on them. Several means of attachment are possible, L-brackets like you find at the hardware store can do the job, screwed, riveted, industrial-velcro'd, double-sided foam sticky taped, magnetically attached (if case is steel instead of aluminum), etc.

In the worst case your cards don't need the airflow and the fan does no harm. In the best case it's well worth the peace of mind and (depending on where you live and when you installed the cards) you may find ambient room temps rise later, as does effectiveness of cooling from dust buildup. Of course, a fan blowing on the cards will tend to accelerate dust buildup, but on average they will stay cooler providing you clean that dust out on an as-needed schedule.

I have a high powered fan facing twords my graphics cards with the side off to circuilate the air. So air circulation isnt an issue

IIRC, there was some issue with some GTX280's having bugged out thermal problems and needed to be RMA'd. It was when they were released in the summer of '08. I would test out the cards in packs of 2's and see if you still get that first card running at 105C at load. That's the "critical temp" where the card will start throttling, and the hallmark of the aforementioned problem was that a GTX280 would reach this temp very quickly under normal load.
