Overclocking - Is it worth it?

Essex innit!
Recently I have been very lazy and don't bother to overclock but after sitting here today about to fire up Batman Arkham City, I thought "should I run AB first?" Me being me, I decided to see what the actual gains are from overclocking and its worth.

I decided to do 2 games for now and the results are quite outstanding. I am running a single Titan for now and the 2 games I thought worth testing were - Tomb Raider and Sleeping Dogs and as these both have their own bench test built in, results should be fairly accurate.

On to the testing methodology - I used no overclocking on the first test in Tomb Raider and received a 44.7 minimum, 58.4 average and 70 maximum. Now that is pretty acceptable to me but what would the benefit of overclocking bring? I decided to go up in 100Mhz levels and leave the memory at stock till the final test. I have a custom, non boosting BIOS and my base clock is 924Mhz. I ran the forth test with clocks of 1224Mhz and stock memory and this returned 58 minimum, 72.7 average and 87.5 maximum. As you can see, my minimum is now equal to my average at stock, which is impressive and for the last test, I ran with a 1224Mhz core and +400 on the memory, which gave me 3405Mhz clocks. The results for that were very impressive and gave a minimum of 62, and average of 75.5 and a maximum of 93.4. This is an increase of 24.4% over the stock clocks :eek: Not to shabby. I did the exact same testing on Sleeping Dogs and the results were just as impressive but only gave a 20% increse from the lowest clocks to the final core and memory overclock.

Anyways, to put it into perspective, I did a nice graph (we all like a graph) and I will test this some more, as there may be bigger gains in some games and lesser in others but on the whole....

Is overclocking worth it? Damned right it is :D

TL: DR

24% increase in Tomb Raider with moving a couple of sliders
20% increase in Sleeping Dogs with moving a couple of sliders
 
I don't bother with it now, I've set the power and temp limit max and increased the volts on my 780 so it boosts to 1100 but I don't bother actually overclocking anymore, the fps increase just isn't noticeable.
 
It is providing there's enough leverage with the CPU. I found both my old 5870 and my current 670 reached a wall which i assumed to be a CPU bus bottleneck.

I tend not to bother too much now. My own eyes will soon tell me what is and what isn't playable.

Good work Gregster :)
 
I don't bother either. If i had one card i might though but with two ive got more fps than i need. So much so id rather run a very low/very quiet fan speed and allow my cards to throttle a bit and keep fan noise to a minimum. I lost a bit of performance from stock but when the fps are high enough already what does it matter?

Good work Gregorio.
 
I agree with the guys that say it isn't worth it or no need but if there is a time when games are seriously pushing our systems, then gains could be quite tangible. I will try out Crysis 3 and see what improvements there are, however, there isn't an 'in game bench', so results could be all over the shop and very inaccurate. I will have a look at 1440P and see what difference there are at that resolution. I predict bigger gains with memory overclocking as well.
 
I think the problem today is the games just haven't been taxing enough to demand that extra fps. The "will my rig play HL2 and Crysis" are long gone. Maybe 4k will change this. Let's hope :)

We simply don't get good PC exclusive titles anymore [or titles that are developed ground up with PC in mind and not console ports]
 
Ran Tomb Raider at 1440P and the results are:

924/3005 clocks
Min 24.3
Avg 39.2
Max 47.1

1224/3405 clocks
Min 39.6
Avg 49.2
Max 58.4

So a gain of 25.5% on those and going from not playable to now playable. 40 fps as a minimum is acceptable to me for this kind of game and 50 fps average are a little low for BF4 for example but this type of game, perfectly acceptable :)
 
Nice work :D

2 things - as I've never owned a Titan, how likely are those top overclocks for most Titan users, and the other thing - maybe do a comparison with your CPU at stock to see how the o/c on the CPU benefits the o/c on the Titan.

As an SLI/Crossfire user though I agree with others, I run a slight overclock on my cards and often wonder why I bother doing that :rolleyes:
 
I run my sli 780s stock for gaming as every game I play is 100 plus fps no need to shorten the life of the cards for a extra 20 fps I don't need.

Overclocking the gfx is good fun for a benchmark or 2 it passes a morning when you get new cards but once the benching is done its back to stock and game on.

This.
 
Never tried overclocking my 7970s.

I've underclocked them though to see how much my CPU is bottlenecking them.

Running them at 925/1375 from stock 1000/1375.
 
For me it shows how you could potentially save money. Taking the 1440P results of Tomb Raider, I didn't consider the stock clocks as acceptable frames and if someone doesn't overclock but wants the best settings, they would need to buy another card for SLI/CF but with moving sliders, that could potentially save money. The same could be said for 1080P and lower end card users. Instead of upgrading, they could just overclock and possibly make the life of the card extend till even overclocking isn't giving the benefit of acceptable frames.

As for the question about my clocks, I can go much more but kept it to what I consider reachable by the masses.
 
I don't tend to bother much with overclocking my 780 to be honest, and given that I'll probably get another 780 soon - I definitely won't bother with OC'ing for gaming as my fps will be high enough for it to not matter.
