I recently ran across a utility that allows the user to overclock their video card. It's very straightforward- easier than I had thought. The risk is, of course, that you will fry your video card by messing with this witchcraft. In fact, simply using the diagnostic caused my video card to get so hot it shut down. My question is- what is the upside? Do you really PERCEIVE an increase in FPS? Do FPS killer missions get noticably better? Any thoughts?

Any thoughts?

I tried it, but it never gave me any appreciable speedups. There's a card-dependent sweet spot there somewhere I'm sure, but I just never found it! It also made my system a tad unstable so I quit doing it after a while...

YMMV however http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

If you want to overclock you should add some more fans/heatsinks otherwise you risk system instability or even permanent damage to the card.

Without extra cooling you will usually be limited to minor changes that will probably only net you a couple of extra FPS.

In my own experience gfx cards can be quite fragile in this area.. http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif For very little real ingame gain. For sure good at pushing benchmarks up but gfx cards can and do go "pffft"

Expensive.

There are/were some models that can be oveclocked quite considerably, say about 30% performance gain. However, if you want to overclock, I suggest that you:

1) read about overclocking possibilities for your card on some specialised PC hardware website
2) ensure that your card had sufficient cooling system (out of box coolers usually are far from being very effective, both performance and noise wise)
3) unless you mess up with voltage settings for your graphics slot, risk of damaging your card is almost nonexistent, setting higher voltage usually means that you increase setting by ONE least possible step in your BIOS
EDIT: +one more thing, graphics card might or might not be the bottleneck of your system, depends on other HW you have in your machine, maybe memory is your problem, or CPU, etc.

...there would be much more, just try to read some more specialised websites...

Conclusion: for overclocking to be really effective, just like with anything else, you need to put into it more effort than just pushing the slider to the right in some utility...

If you try to OC a machine with a week CPU and a top end GPU, you will likely see no gain. This game is very CPU dependent and a more powerful CPU(or OC'd) will gain you more FPS on average.

However, If you have a very good CPU but only a mediocre GPU, Then OC'ing the GPU may gain you significant FPS (as long as the GPU is a good overclocker).

It is all about system balance.

I didn't even want to get into processor overclocking but since we're talking about it... Anybody know what you can squeeze out of an 3GHz P4 Northwood through overclocking? We're talking reasonably and safely here too- I don't want to build a rig which requires liquid nitrogen.

Thanks for your responses so far about the video card.

Only if you run very high resolutions does it warrant the risk of OCing. If done correctly its not harmful to your hardware at all. But if you want to see any real gain it usually will not happen until you add the high res and AA as well as AF. If you run 1024 then there is no real benefit to OCing. Now if you run above 1600 give it a shot, but read up on how to do it properly. It always helps out if you google your card and see how others have done when it comes to overlclocking. Just dont expect an extra 30fps or anything like that.

Better off just buying the card that will run everything with no problems, or end up paying for a whole new rig if ya OC wrong..aint worth it to me, less ya know zactly what your doing, and just how much of a difference are you really gonna see?

I have Gainward 7800GS+ AGP Golden sample, which has an overclock selection right out of the box (I won't build my next system for about a year, so I needed all the AGP umph I could get for 3D work). I see no real difference, while I get some ocassional tearing. It can go to 450 Core and 625 memory, but I leave it at stock settings now.

No.

It's alot of work (if done properly), for very little gain. And, there's always the chance of damaging a very expensive piece of hardware.

Basically though, if you want to check it out, it'd be best to research your GPU, and the memory chips that are installed on the card.
This means looking up the part numbers, to see what thay are actually capable of.
You need to know...
What type/speed is the RAM?
What generation is the GPU?
What bios is the card using?

Alot of work, and some risk.
If you just start overclocking your video card, without "slow,thorough,painstaking" testing...the risk factor goes up.

Dont forget the heat factor. When you overclock a video card, it generates more heat. This can effect your on-board chips,RAM,CPU,etc.

If you want 350.00 speed from a 275.00 card...its much better to wait until you can come up with the 75.00 for the faster card.

When it comes to cpus, I'm the overclocker from h e double hockey sticks. But video cards?...Thanks anyway...been there...done that...not worth the trouble.

My two cents.
As for the CPU overclocking...that depends on your motherboards make/model...for starters.

It's worth it for me. The key is to understand what you're doing. Try OverclockersClub (http://forums.overclockersclub.com/). Lots of friendly folks there.

The gains are slight, if noticeable at all, and nothing appreciable. When stressed many of the latest video cards run close to their safe thermal limits anyway, so you're taking a bit of a risk in OC'ing those. You'll risk a power shutdown or a spontaneous system reboot because of insufficient juice (OC'ing requires more power). Worse yet, you could potentially damage your video card.

Ask yourself, is that worth it?

only play with overclocking if U have cashflow enough to be able to replace your card if it goes wrong.

I asked the same question some time back.
I personally can't generate cashflows of any kind so I already stopped thinking about it there.

If u do have the cashflow why not buy a better card, as someone suggested?

short awsner IMHO no. not worth the risk. and by the time you spend mony on water cooloing ect your a good ways to buying a new card anyway.

pretty risky stuff IMO,for a very little (most of the time unoticed) "improvement".
Better buy a new card, many makers have factory overclocked cards, which means there is a Garantee ....

To keep a complex question simple... over-clocking the VGA in itself has little improvement in Frame-rate on IL2 or other older CPU dependent programs. I average a 5% performance increase over-clocked 12% with a 1950CF/XTX setup and the ATI Overdrive utility. I am currently bottlenecked by a P4 Prescott @ 3.97Ghz. Note that the 1950XTX cards already have a great fan/heatsink, only needing a drop of ArcticSilver. I do not see any difference using the native resolution-refresh on my 37" Westy and IL2.

Edit: This is a 3DMark06 result with the Mobo Overclocked to match the fsb, ram, etc. and ATI overdrive in crossfire. (Air-Cooling CPU 3.740Ghz @ 49.7c and GPU's @ 78.9c.)

Overclocking gains are generally very small, I would not bother.

What can be worth a lot is if you research your particular video card and find out if it is possible to "flash" it's firmware to convert it to a higher spec card.
A lot of folks in the know have bough certain lower range cards at half the price of the top of the line, and have flashed the bios to open up locked pixel piplines and such, this can reap huge increases in power and is very much worth looking into.

I tried, successfully, overclocking my old 6800 Ultra, got about 2 extra fps for my efforts. Overclocking the cpu (Athlon 64 - 4000) gained a bit more and smoothed out the game play. My new 7950GT runs at stock speeds. I just don't feel that overclocking the video card is nearly as much of a benefit in flight sims as overclocking the cpu. In either case, watch those temperatures, you don't want to cook something.

I'll take all these responses as a pretty definitive collective "NO, NOT WORTH THE RISK!"

It's funny too, in doing a search on overclocking, I found that most threads mentioning overclocking go as follows-

Someone posts- "I'm having a big technical issue" of some sort or another.

The first response is usually the question- "Are you overclocking?"

Seems like it wouldn't occur to people to ask that question first shot out of the gun if overclocking didn't cause a ton of tehinical issues.

In any event maybe this discussion will prevent some poor kid from frying his video card.

I tried overclocking once. A gravity well opened in my den and strange blue men emerged. We fought a battle of wits using cannons made from six dimensional, dried Cuban sponges. I won and they went back into their hole. I'll try overclocking again when I've gathered more sponges.

Actually, what bun-bun said makes more sense to me than what most of these oc forums try to explain. But then, I'm only a former high level systems analyst with an engineering background. I'd rather figure my taxes than overclock my computer. I just like simple things.

Totally agree with the guys saying that overclocking gains are small on most hardware, especially gfx cards.

The only time I ever noticed a difference from overclocking anything was an Athlon XP2500 overclocked to a 3200+ which is generally a big overclock compared to what most hardware can do, and this was just because that batch of chips were very good.

I wouldnt bother ocing a gfx card, say you do an good overclock of 10% extra speed. The only time you really need it is when you have a low framerate in games, so your game is running at 10fps, then you MIGHT see 11fps from your 10% overclock.

Will you really be able to tell the difference between 10fps and 11 fps?

By all means try it, especially if you hardware is old, but I think like most of us you will decide that the gains are really mnot worth the (effort+the risk). (even tho the risk is small)
