Is that really true? I have it set on maximum as per guide (quick version)....

I think generally it's Okay leaving it on Max. But there are a few things to consider.

 

1. If you leave it on max and fold 24/7 for a long time it might shorten the life span. Might.

 

2. If you plan of keeping the card beyond, say over two or three years. Lowering it a bit would be a good idea, just to be on the safe side.

 

3. The makers of the cards, and many but not all GPU OC applications are fairly conservative. After all, some cards are just simply sub-standard, just

scrape through final QT. Other "Golden cards," can go beyond the max, but not recommended for 24/7 continuous use (fah for example).

 

The point I am making in 3. is that no company (especially card manufactures, third party OC vs etc.) don't want lots of RMAs. In the case of OC

software, no RMA of course, but they don't want to be blamed for frying lots of GPUs.

 

4. In the end, after reading up about it (as you have) it's a personal choice, and depends on how conservative or willing to really push it one is, and

of course if the card overheats, it will need to be lowered. (core MHz, voltages, or both depending on the card.)

Quite surprised / unsure what to think:
I'm at +700 mem clock...no problems bench past without any problems....thoughts?





UPDATE:


This is an insane score for me so far!


3D mark passed:

+rep for your answer!
I will tone it down as I intend to fold a bit more after I get stable.

Totally dubbed, thanks man, I appreciate that!

 

There are so many differing opinions on this kind of matter that I feel any comments should be backed up with a link, pic, or just stick to the logic of electricity, heat, component quality etc etc.

 

Cheers!

totally makes sense man! I agree with it too smile.gif!
Now I just have to figure out my GPU OC!

If anyone is curious, this card tears up Assassin's Creed IV: Black Flag! Depending on how important AA is to you i'm getting 45-60fps@2560X1440 95% of the time (only dips into 30 for the dark stormy ship scenes briefly)

"Ubisoft has confirmed some technical details about Assassin's Creed 4: Black Flag on next-gen consoles i.e. the PS4 and Xbox One, as the game has a locked framerate of 30fps on both devices but will run at 1080p on the PS4 (thanks to a day-one patch) and 900p on Xbox One."

Yeah, I had no idea an OC'd 670 was this much more powerful than current consoles, I had only assumed until now. Really though 900p@30fps, total joke, I hope true next-gen games get better treatment than this. I'm guessing the next-gen only titles won't be as easy to run as this title, but we will see once they start popping up.

I created my own thread, in order not to cramp this one - any advice is appreciated - thanks!

I'm still curious about the core voltage.
Right now I crashed at +60 with either +450 or +600 mem clock.
Passed over 9 runs of heaven bench.

I can only think of two things:
My core clock is almost there, just reduce it a little with +600 mem and I should be fine.
My core voltage is on stock +0 - if I increase it to +100 it will allow greater stability but a shorter lifespan?

I'm just worried about what the voltage can affect.
I know in CPUs = more heat.
And from what I read it is the same principal in GPUs. I'm well under 75c, never passing the 70c mark due to my fan profile.
Longevity concerns - there's tghe same concern for CPUs, but it is honestly like reducing it by 1year in a 10year cycle, and in less than 3-4years everyone will upgrade anyway - so what are people's thoughts on CORE VOLTAGE on GPUs?
If you had the option to enable it would you change it?

I know the cards are also limited/capped if not flashed. Thus meaning you can't really fry the chip - unlike with CPUs (ie 1.7v on ivy bridge = burnt, no matter the temp)


EDIT:
I ran heaven with +0 and then after with +100 and closed GPUZ after the +0 test.
My voltage doesn't go over 1.1750v no matter which setting it is on and on BOTH settings had the same MAX reading of 1.1750v

I'm still not convinced heaven 3.0 is an adequate stress test compared to heavy gaming (Crysis 3 and the like). It will always let me scale up the clocks (at least mem) to points where games will crash.

I just ordered RAM coolers from Frozen CPU. I'll have to see if this helps the OC a bit more.

The other thing is that on 3dMark 11 my score went up pretty dramatically without touching the overclock.

this normal? I'm pretty excited with the results and can't believe how well this worked out.

How did you mount the H80's? I've seen this done before but it was pretty ghetto, zip ties etc haha.
