Hi,

Guys I'm stuck badly here. Plz help me.

Continuing on with this post (http://www.tomshardware.com/answers/id-2042865/gigabyte...), I've got serious doubts that my card is performing to its full potential.

The reason behind this tentative conclusion is that while attempting to OC the card, I figured out that it was clearly not reaching the power and temperature thresholds I set (not even close to the mark of temp. throttling). Many of the scenes in Unigine Valley ran at mere 30fps even at a stable +70 core offset (on top of 1137 base/default). I don't have any problems thinking that this is the maximum OC I could get out of my card, but the issue is that the temperature never even reaches 70C (way below the limit I set, i.e. 95C), which could most definitely be due to the fact that the TDP never crosses ~83%. I don't understand how to make it utilize the power/temp. limits properly.

This whole thing reminded me of the many instances some months back, when some games had kept freezing (without any OC) with me having no clue as to why. Some notable names are Resident Evil 5 (random freezing/crashing), Bioshock 1 (mostly at weapons and plasmid menu) and of course 2007's Crysis (random freezing/crashing and especially at the last boss enemy scene, which indeed seemed like an immensely graphics intensive part). I believe this exactly would've been the case where my GPU might not be able to push itself properly and started freezing like crazy. Techpowerup review shows 63.4fps average (1920x1080 - 4xAA) in Crysis while I clearly remember my 770 stuck at ~50 (same settings as techpowerup) almost all the time!!! This is crazy really.

I'm in need of some urgent help guys. Really appreciate any suggestions/guidance.

Thanks very much in advance.

What CPU do you have. I might be able to help if i know that. THANKS!

What CPU you have ?
try turning v-sync off
it could be bottleneck

Sorry guys, I was updating my post a little bit while you guys replied.

Well, the cpu is i5 3570.

Are you talking about turning vsync off in it's entirety or just for the OC process. For games, I've set it to adaptive Vsync which should only be applied once it goes above 60fps (my monitor's refresh rate). Is this correct?

PSU? WATTs?

Ok. Try all of these

1. Unpark your CPU cores. (find video on yourube)
2. turn vsync off
3. if you can, try a different GPU
4. re install drivers
5. send your card back and get a new one, if you can.

1. Do you mean OC the CPU? It's a non-OC model.
2. Will try.
3. Can't :( .
4. Already tried.
5. Will do if all else fails.

Thanks.

Ok. So turning off vsync in Valley itself somehow helped (nvidia control panel is set @ Adaptive), and the card's now reaching up to ~85% TDP and 71C temp with almost consistent 60fps or above, but only upto +70 core offset (starts freezing/downclocking to 1215 @ +80, within just a minute in Valley). I had read somewhere here on Tom's that Valley clock indications are not good. Well it's vsync setting is also F%$^% up I believe.

Now when we say that every single card is different in terms of it's OC'ing capacity, what exactly do we mean here? What I assume is that if mine is reaching the temp or power target (say 106%/90C) and throttling the clocks @ +80 core, someone else's will react the same way @ +100 or may be +60. Is this correct? Or (like in my case) it will just randomly start throttling/downclocking without reaching either of the limits?

Plz help me urgently so that, if it must be returned against warranty, I could do it tomorrow.

Thanks a bunch guys.

What score do you get in Valley, on Extreme HD preset?

Power/Temp targets in Precision: 110%/93C
GPU Clock Offset: +60
MEM @ stock

Valley ExtremeHD (except for AAx4 instead of x8) stats:
FPS: 61.7
Score: 2580
Min/Max FPS: 20.7/129.5

Precision logs show max power/temp = 85%/70C.

Above +60 (at the same settings), Valley does not complete the benchmark; freezes randomly on any scene for a couple of seconds, downclocks to 1215 and continues. The logs never show either of the limits getting reached even for a second!!

EDIT:
It's completely random/erratic really!

One time it completes the Valley test @ +70 core and +250 MEM, another time it doesn't!!! Even though I give enough time to the GPU to cool down properly between the tests. I'm really clueless as to what's wrong with it.

Try lowering the vram clock speed, by 50mhz and run again just to test.

Hmm. May be this sums everything up quite nicely. I mean all the problems that I've been facing so far with the card. That is:

1. Windows 7 desktop refresh rate issue since the beginning (while switching between windows I can sometimes literally see them dying on the screen with the fading effect that windows has)

2. Like I mentioned in the original post, games crashing (most definitely due to not keeping up with the power/temp thresholds and prematurely downclocking drastically)

3. Erratic behavior during OC'ing attempts.

Well, it's imperative that I go through all this shite. They'll keep it for repair first and God knows what.. PHEW!! :) . It's been 7 months since the purchase. Wouldn't have found out if I didn't attempt OC'ing.

Does any other friend of mine here have any other suggestions or things that I could try, before slamming this card back on the retailer's face?
