GTX550Ti Overclocking Issues

dk_lightning

Im trying to see how far i can push my 550Ti but I cant seem to get past 1000Mhz on the core.

1000Mhz runs fine but if i try to set it to anything past that the change wont apply and within about 20 seconds or so the card clocks down to 405Mhz and stays there untill i drop the OC back to 1000Mhz or less.

Cant for the life of me figure out whats going on with it.

Anyone got some ideas on this one?

If you already increased the fan speed and the voltage, then there is nothing you can do beyond a new cooler if you wanted. Assuming you tried voltage and fan speed, then you have already hit your cards bottom-line. Congratz.

How would a new cooler help me oc more..

All other 550ti's ive seen oc past 1Ghz fine :\

If it is getting to hot... a new cooler... still not obvious? Maybe I should have specified a better cooler, but I don't know what cooler you have.

And it sucks, it's the luck of the draw when it comes to this, you (like myself) are simply stuck with one of those completely ordinary, way out of the ball-park of one of those "golden" cards.

If you are still not sure, and feeling anal, you could try different overclocking programs. Some people swear certain ones OC better for them, but that simply was not the case for me.

My temps are fine. 30c idle 60-70c in game. or with fan speed on 70% i get 50-60c in game.

Should i be able to move this new power limit slider or is that a 600 card feature?

It's a 670 and 680 feature. You should probably change the skin to the legacy version.

Ive got the EVG 550Ti FPB and i also keep mine at 1000mhz core clock from the stock 951mhz. Ive hit 1022 but anything past that seems to be a bit unstable in certain games, in Max Payne 3 1022mhz made the game stutter a bit but using 1000mhz keeps it perfectly stable.

This is all at my stock voltage of 1.112 though, so im not sure, maybe more voltage would allow me to go higher but everything runs fine for my resolution so i just keep it at 1000mhz core clock.

So yours goes past 1ghz ok.

Mine is fine at 1Ghz. set it to 1001 and the card just wont clock up under stress and sits in low power clocks untill i drop it to 1000 and the card then clocks up to 1000, set it to 1001 again and the card clocks down to 450 or 51Mhz.

Very odd

Yeah thats really weird, even just the 1 mhz increment and it downclocks? Wow, weird indeed. Not sure how to explain that one lol. I guess you should just keep it at 1000mhz then unless you figure out whats going on with that.

Check out your voltage under load and post back. It might be undervolting because your card is running pretty cool for it to not clock up by 1 mhz increment at those low temps.

It may well be a driver issue.. Once my internet is working right ill download the newest version and see if that helps my problem and report back

UPDATE:

I just noticed in Kombuster it says GPU Throttling -3Mhz when i OC to 1002Mhz

How can i stop the gpu from doing this?

KopyKat007 · 06-13-2012, 00:45 | posts: 127 | Location: Canada

Ive never used Kombustor, downloading now and im gonna see what mine does with it.

KopyKat007 · 06-13-2012, 01:01 | posts: 127 | Location: Canada

Yeah thats kinda funny, at 1000mhz with mine it doesn't have any - GPU throttling and it says its using 999 core clock, but if i raise my core clock to say 1011, it says its throttling -12 which tells me anything above 1000 mhz on this card is a bit much or voltage needs to be increased or something...

And what if you edit the bios and flash?

Truthfully ive never done that since im pretty happy with my results on stock voltage, i might check out the bios editing guide sticky though, i just don't want to risk screwing something for minimal gains or something like that.

How much can be gained from doing that?

EDIT: Looks pretty complicating lol, i think ill stick with my max OC with stock voltage lol

From the odd little bits i can find on google, it seems its the nvidia driver thats doing the throttling??

dk_lightning · 06-22-2012, 16:46 | posts: 625 | Location: North Wales

I have now tried a fair few older drivers. Gone back 10 versions so far and i still cant OC past 1000Mhz

Still makes no sence why the gpu is being throttled. Does nvidia not want anyone to go past 1000??

dk_lightning · 06-25-2012, 23:40 | posts: 625 | Location: North Wales

Can i please get some help here with this??

Nvidia inspector shows the 1100Mhz core ive set but the actual core speed is 1000Mhz

Its not a stability issue or cooling issue. Something somewhere is stopping it from overclocking more than 1000Mhz. but the question is, what?

KopyKat007 · 06-25-2012, 23:58 | posts: 127 | Location: Canada

I really don't know what to tell you, if i did i would, i just keep mine at 1000mhz core so im not sure what is stopping it from going beyond that for you.

I got the same issue with my GTX 560's (non ti)
1mhz over 1000mhz and the cards instantly down clock.

But both cards are happy doing 1000mhz @ v1.100
Doesn't matter what voltage I feed the cards, tried every voltage upto max voltage of v1.212.
It's not like the cards even try to run when over 1000+, just instant down clock as soon as I run any 3D bench.
Using AB 2.2.2 to oc.
Both cards run in the 60c ~ 66c at 1000mhz at max load and never throttle.
1mhz more and instant throttle.

Maybe your brand of card isn't allowed to go over. What brand of 550 ti do you have?

It was a PNY but i just exchanged it for an Asus.

And guess what? It does the exact same thing.

Im sure this is driver related. Maybe bios but i doubt it.

UPDATE!!

Im using 296.10 drivers and i can now oc past 1000Mhz! im at 150mhz and its stable.

So now the question is this.

Why the bloody hell are nvidia limiting the amount we can oc our cards?!

yeah man we need to use 296.10 drivers.. why nvidia limit oc to 1000mhz ? what the hell...
anyway..I got more FPS using 296 than 310.70 =)
so I use physx from 310 and driver from 296
