Yeah it does seem to be a very similar problem, and the way i read it is they believe its the PT whereas for me it is voltage.
I only just realised this isnt an Australian forum lol. Must be pretty early in the morning for you guys ay? Well if i just taught an experienced OCer something that would make me a happy man. Hopefully Arizonian and SeanPoe would have learnt from this too. Will update some more of what i have found when there is enough info. Just benchmarked at 1.00V and got 1110 in heaven. So will start increasing CC until i get a suitable clock then will start playing with voltages again. Lets wait and see.
Hopefully i will post up more tonight, (its 10pm here) but if not will definatly share more tomorrow night.
Ok something is really not right here. I had just posted all this following with pics only to realise after i restart my comp i forgot to set the PT at 145% so i went back and removed the pics from the host. Yeah stupid mistake i know. So the text is now edited to reflect this. And is definatly worth reading considering the TP was 45% lower than it should have been.
Here we have
100%PT 1.00V +80CC Heaven= 1110
So from there, i went to +95CC (driver crash) to +92CC (very bad/strange score 1st run, driver crash 2nd run) and ended up at
100%PT 1.00V +90CC Heaven= 1110. Same score as +80CC EXCEPT one of the lowest min fps, and the highest max fps, and the average was the same. I found that quite strange.
So, what happens now if we nudge the volts back to 1.025? This...
100%PT 1.025V +90CC Heaven= 1072 So we lost 28 points!
The reason you lost points here is because by increasing the voltage you also increased the power draw slightly, which would put you over your set power target causing a GPU throttle. You would need to increase the PT and the voltage together to avoid this. Try 115% PT and 1.025V +90CC and see what you get.

Ok ya wanna play that game huh, lets take it down to 0.975. Which happens to be the lowest she will go.
100%PT 0.975V +90CC Heaven= 1115. A 5 point jump from 1.00V
This is the opposite of what i just described above. By lowering the voltage you also decreased the power draw slightly which then prevented a power-related throttle.

And this is where it gets really strange. After i realised my mistake i set everything back to what its was meant to be (145%TP 1.00V +90CC), and guess what? Driver crash. Ok i thought, resets computer, sets everything up again, driver crash again. Ok. What the frick is happening. The only thing i know right now is im tired as all hell and have to work in the morning. When i knock off from work tomorrow this will be my top priority. Expect to hear from me again soon!
Try 145% PT, 1.175V, +89CC. I'm not sure why you're being so reluctant to try maxing out the voltage slider. If that crashes, then try 122% PT, 1.175V and +89CC. This would be a nice test to apply what i learned from Arizonian.

I've honestly only seen Arizonian and Carcin0Genic getting better performance at a lower power target. That's why i've always just recommended to max it out (because, at least on paper, I'm not sure why exactly reducing it would lead to a performance increase). I'll recommend everyone at least try reducing their power target to see what happens from now on.

Thats basically where im at at the moment. So yeah to me it looks like Volts are definatly affecting my OC. Notice in the last 2 tests the score only increased my 25 points? Maybe im getting close and im starting to think you definatly need the right volts for the right OC, or at least in my case. This is the first time i have OCed a gpu, and OCed my first cpu just yesterday. So, What do ya think?
And my apologies about the wall of screenies.

I hate to say this, but i'm quite certain that at least the first 5 tests are bugged. You should never be getting an average FPS under around 40, even at stock speeds. This indicates that Heaven is running in 2d mode instead of 3d mode. Like I've said before, i have no idea why this happens, but it seems to happen 1 out of 30 runs and then the only way to fix it is to restart your computer. What i usually do is watch the average FPS down in the bottom-right corner, and if it doesn't break 40 fps by the end of the second area of the benchmark, i just assume it's bugged.

I'd say restart your computer and then run Heaven again with the same settings as the first test (145%PT 1.175V +80CC) and then post the graphs so i can look at them.

And i wouldnt say im reluctant to increase voltage, just that from what i can see volts are hurting my OC.

In between EVERY run was a full restart to avoid any 'bugs' in Heaven.
Will post update this post soon with the 145% 1.175V +80C you requested, but internet has been capped so uploading is going really slow.
Ok so restart was done, as i am now doing between all runs. Lol i think my computer is starting to hate me.

So what do you think? The best run i have had so far was 100%PT at 0.975V And +90C. I have repeated this test after a restart and got the same score as last time (Heaven = 1113)

Currently overclocking my reference EVGA 670.


Temps have always been at 60-61C since I started.
1275MHz Gpu clock
1677 memory clock

Will get closer to my max overclock on it tomorrow.

One question that I hope someone can answer for me so I know when I wake up. If I don't crash on Heaven but do on BF3 after playing for around 5-10 minutes, could memory being low in comparison to my GPU clock be part of the problem? I didn't see artifacts or anything when doing the memory part of the overclock guide but I want to keep as much performance as possible fps-wise. I should probably tinker with the memory tomorrow since my core clock is definitely stable.

i did what drboss said: let the heaven bench run in looped mode and see how long it can last for without crashing. if the clocks crash: reboot, lower the core clock, and test again to see if it stays on longer. keep doing this till it can last a few good 2+ hours.

Something strange is definitely happening with your card. Because you restarted in-between tests, it's safe to say it was not Heaven that was bugged. However, as you can see in the graphs, your GPU core clock is all over the place. For example, even in your best run, the core clock is spiking up and down continuously throughout the run (when it should be constantly at your maximum boost). In your worst run in the first screenshot, your GPU is running at around 300-600MHz the entire run. I'd be shocked if that type of throttle (1000-700Mhz throttle, 1300Mhz to 300-600Mhz) is purely power-related (it could be, but that would indicate you have a dud card). I want to say that your card is having trouble switching to 3d mode or coming out of a power-saving state, but i don't know how to test for that. Consider private messaging BrettJV and asking him what he thinks of all this (ask him to post in this thread too please, i want to see what he has to say).

This is for everyone.

Why Heaven crashes on high OC sometimes it happen in low OC too and 3DMark is stable in all my high OC and low OC? I had try Heaven on all my OC settings and it still crashes I cannot get any high score in heaven like it supposed to be and the same OC on 3DMark are so smooth.3DMark are very stable in all my settings and Heaven won't like it at all.I did try all you can think of , New Heaven Download, windows installation with stock drivers only an so on and Heaven pisses me off.
all my 3DMark benchs, I'm kinda lazy now to post all links but here A'm.





Top Card


This is my 15k on 3DMark that never pass Heaven

To me looks like Heaven are not optmized like 3DMark for High OC. my2cents

Should power draw stay near 100% when running full load on Heaven? Even if I loop it for 2 hours?
I noticed TDP drops to 80-90% and it kills fps/heaven score (this is without alt-tabing so it cant be stuck in 2D mode)

Also, are there any advantages of lowering voltage to 1.162? I see some people with crazy but stable overclock dont always have it maxed out at 1.175.

both my FTW are around the 1275-1283 GPU MBF/ 1880-1900 Mem...but still need to ensure long term stability.

Also, is it still accurate if i loop Heaven but have my monitor off? Yes right?

And artifacts appearing = overclock is detrimental to the card? Or will it not affect the card's lifespan?

My problem is that I can get Heaven to bench just fine, but when I play BF3, after about 5 minutes or less of playing, the game crashes. Heaven has been fine.
