AMD claims 1.36 TFflop of processing power for 4890. It is very interesting how much electrical power needed to explore full potential of 4890. From GPGPU point of view high power draw may mean that some "reference design" cards have "limited usability".Originally Posted by largon
For your information, OCCT PT 3.1.0 Stable has just been released.
Same as RC1, a couple of very small bugfixes has been made (really, nothing major, and nothing going into the functioning of the GPU test. Just interface quirks).
It's available from www.ocbase.com , as usual.
Don't be surprised if you get the 3.1.0 "stable" from the beta download links now
And really, i don't think the "OCCT is a power virus" debate is something useful here. Why don't we start another thread somewhere else about that ?LordEC911, what do you think about that ? This thread is dedicated about the problem OCCT is arriving, not OCCT himself.
Let's try to stay on topic
Actually it doesn't matter how you call that (power virus, electrical microbe or whatever) - such type of software should not cause for hardware malfunction when proper cooling is used. Moreover such type of software was released, for example, by Intel to test cooling solution of CPUs (LINPACK, BurnTest e.t.c)
Something's wrong. With this version the GPU bench doesn't even start. Says "Error Detected" and the test aborts as soon as the 3D test should start. It doesn't crash, it aborts and stays on desktop.
RC1 still works, though.
You were not supposed to see this.
Dude... It's not a power virus. You're wrong, and Praxis is correct. Now please move on with your life.

largon, it works fine on my machine.
sry, but who the f came up with this "power virus" crap? rofl, hilarious.never heard of that before.
"crysis stresses my system sooo much, it even crashed a few times! crysis is a crash virus, omfg, call mcafee!"
according to this definition every stability test is a power virus, which isn't true.

Power virus or not, it is not the subject of this tread, so...
So I did my tests on the french topic of OCCT, and the results are clear to me:
With both my HIS HD 4890 reference design, I have a blackscreen in crossfire or single, after 5s test, then a BSOD and dump it and with the original frequencies and voltages as well when i use fullscreen mode.
My power supply is good, can support 2x GTX295 vmod & i7 965 XE under ln ², so it is not the reason...
So I spent time to test more precisely, especially since my HD 4890 takes furmark, Crysis or Fallout III at 1000/1200 so totally stable.
It's frustrating ...
For me, the theory of82A is right.
With my oc card, OCCT GPU at 700X700 i can reach 81.97A but when I exceed this value, it's black screen directly!

- Just, call me dami1 -
- We do not born expert, but we can become one -
can anyone rule out bios bugs with certain cards?
i see saphire assus palit and others have updated their video bios files a couple of times based on the card's P/N
I don't get it, what are those amperage figures RT & GPU-Z display?
It can't be the total vDDC phase amperage, nor it can't be a single phase amperage.
And why does RT give totally different amperage figures than GPU-Z? GPU-Z recorded 83.30A while RT reported 48.79A for the same point of time when I had both GPU-Z and RT write a log during the same OCCT test run...

So we finally have the most suited explanation...
Now to solutions if any needed...
Beacause if this is the case, then it is only occt related.

I don't think that's true, because with VSync disabled the card's VRM screams (indicating high load). When it's capped at some number below what the card is capable to do it doesn't scream at all, temperatures are lower, power draw is lower, etc. If you have that behaviour with OCCT it's most likely your fault, because every game I've with VSync enabled works as it should.V-sync, on ATI cards, doesn't reduce the load. Every frame is still calculated, just not sent to the screen. I was surprised at first, but you give it some thought, it's normal
Friends shouldn't let friends use Windows 7 until Microsoft fixes Windows Explorer (link)
I went back to the 3870 and I was satisfied it wasn't going to crash. Is my Sapphire 4850 crashing because it is underpowered or a weak cooler, I mean geesh, it got to 120C good or bad. Sapphire uses a one slot solution.For your information, OCCT PT 3.1.0 Stable has just been released.

there yo go bringing intel into a amd thread again lol, if that was someone droping a dig at amd you would be crying like a girl.qft!
Vsync does affect power consumption.
I measured ingame wall draw Left 4 Dead double buffering on and off. Vsync off the system draws ~40W more.
You were not supposed to see this.
which is a good reason to use vsync unless the game has input lag issues with it enabled
Doubt the cooling matters much, because the vregs on mine are air cooled and typically get almost just as hot as an air-cooled card. Plus, Tetedeiench says temp shouldn't matter.
I suppose the 512MB vs 1024MB could be a difference but is really drawing that much more power for the memory?
I've gotten lost in the mess of useless flame posts - Have there been any 3 phase 1024MB cards that had no issue, or any 512MB 3 phase cards that did?

SparkyJJO,
Memory is powered independently from the core and it's the core amperage that skyrockets so I'd rule out memory power issues.
Besides, GDDR5 consumes ~3-4W per chip.
What kind of amperage figures are you getting in GPU-Z/Rivatuner with your OCCT stable HD4870?
You were not supposed to see this.
Mine is off, I'll try those games mentioned with it on to see if it makes a difference, thanks.

um, it has happend 2 times at least in this thread.
Here was the latest.

Particle's First Rule of Online Technical Discussion:
As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.
Rule 1A:
Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.
Rule 2:
When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.
Rule 2A:
When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.
Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!
oh.. ok
I guess bringing cheap video cards does have it's down sides.

81.3 A, And that is overclocked on the core a little bit too. Perhaps mine is just a better core that is more efficient
vrms shot up to 110-115C pretty fast.
