Is this normal?

[HarvesterOfSorrow]

So my consern is my gpu z reportings , my card is rated at about 200w but on gpu z i get vddc power 63W on msi kombustor and vddc current 55.9A whitch seems low when watching others r9 280 vddc currents. like on this https://www.google.fi/search?q=hd+7950+vddc+current&biw...
and this https://www.google.fi/search?q=hd+7950+vddc+current&biw...

I may be wrong, but VDDC is calculated using the the GPU power line, usually around 1.1V to 1.3V, where your 200W rating is calculated using the entire 12V line and what it supplies to the entire card.

 

[HarvesterOfSorrow]

GPU PCI-E cables give 12V right? so my psu gives
+ 12V / 50 A so under load that vddc current 55A is fine? thx for answer

 

[sneekypeet]

The 12V lead may provide 50A, but it isn't likely that the draw is that high. I would wait for someone more electrically savvy to reply, I was just trying to help out with why the huge difference in numbers.

 

[HarvesterOfSorrow]

Ok i assume @W1zzard can help, but i just googled some pics and some gpu z reports are same as mine but some are more higher, dunno then

Nope during load 55A is stable, but i scored 2333 points on unigine valley 1080p ultra no aa and that score is excatly same as on some test i saw

 

[HarvesterOfSorrow]

makes sense @little cat
but what is that 63W when card probaply draws more that 200W on specs.

If the load is not 100% . Might post photos

 

[HarvesterOfSorrow]

load 99% while gaming crysis ultra

 

[little cat]

Post some images . What is clear , 55.9A is at the core voltage , seen in GPU-Z . 12V are converted to lower voltage to power the chip .

I ran MSI Kombustor.

load 27% , thats why 64W

current : core voltage x current Amp = Watts

 

[HarvesterOfSorrow]

if you watch that red bar load is 99% its 27% because i had to close stress test when taking screenshot

 

[little cat]

When playing a game ?
Also i could not know wheter it was set at max or current value

Is the card running at x4 PCI-E speed ?

You're seeing the wattage when the card is no longer under load - hence the 27% load and 64W that you see listed. it appears the screenshot you took of GPU-Z was after you stopped the kombuster test or you did an alt+tab to change the computer's focus to the GPU-Z program and thus left Kombuster running in the background.

Either way, everything is working fine from the image you posted from what I can tell.

Why is fan speed at 100% ?

Sure you can.. .it says MAX/MIN for those values or it says nothing for current/live values.

Oy, you deleted another post....................

 

[HarvesterOfSorrow]

when card is at full load vddc current, power etc are those what are on screenshot because i can monitor gpu z on secondary screen aswell, fan speed is 100% because it is very silent 1250 or 1350rpm fan (cant remember whitch)

I have putted 'show max value' on those three last sensor and gpu temp sensor so 65W is on full load (99%)

 

[HarvesterOfSorrow]

OK i watched GPU Z results from LegitReviews and theyre scores are pretty mutch same as mine, this pic is 30 mins. Crysis 3 ultra. So everything is fine, and this review was same GPU(Sapphire dual x) I have no idea why some people have so different values, but that doesnt matter after i checked this:

 

[Toothless]

Dude, edit your posts and quit double/triple posting.

 

[little cat]

Which PCI-E slot is used ? Often one works at x16 and the second at x4 ?

If this is fine and the card scores the right points in benchmarks , my guess is either a bad sensor or GPU-Z reading is wrong .

 

[HarvesterOfSorrow]

Im using it on PCIE 2.0 x16(x4 mode) since it wont fit to 3.0x16 due accelero hybrid 2 backheatsink, i dont think its bad sensor since legitreviews GPU z is showing same as mine. I think thread can be closed now. Many thanks to answers.

I saw similar images so most likely GPU-Z reading is wrong for all R9 280 or of a certain brand
