BSOD on failed overclock?

[neblur]

Hi there i made a thread yesterday about Overclocking my gpu, I got away with a small one witch is good and all But a Awesome dude! the guy who helped me with my overclock [Imginy] who suggested "On my msi 660ti I run 7000mhz memory and plus 70 on the core as my normal overclock for playing games." So after getting a stable overclock with his previous suggestion i go and give this a try..... BAM BSOD after ******** my pants and thinking that a fried my gpu i restart my machine, Everything was fine and all witch is good But what i want to know is what could have caused this and is the dangerous? If you have any suggestions on what i can try maybe push a bit more out of the card without a BSOD then i would be more that happy to give it a try.

Your best bet is to look at the thread i posted yesterday yo see where i am coming from.

BSOD shows that your OC is unstable and nothing to worry about. If I push my cards too hard, I will get the same and will either get "The display driver has stopped and has recovered" or I will get a BSOD.

Either of those are normal annd it means you are trying to go past your previous stable OC. Just reel it back a bit and see how you get on

The card should be fine, usually my driver crashes when the overclock is too much and I'm running something like heaven benchmark to test it, and it's not caused a problem.

I'd recommend going back to your stable overclock, ensure it works - then play cat and mouse. Increase your memory/core clock little by little (10-15Mhz) and test it again, you'll likely find you'll get get another BSOD or some other error which is fine - you know your limits then. After you've found your maximums, ensure GPU temps do not go crazy while gaming/stress testing and of course the overlock remains stable.

Hope that helps

Thanks for the reply! Good to know its not bad or anything. I was a little worried =) For a first time Overclock like me you could understand why i was a little worried =P I have it running at this Very stable atm.

What i was wondering is that if it would be safe to try this since its the same card/chip, If it would work on my card.

I am willing to try it now that i know the BSOD is noughting major...

Also Would i have to adjust the volatage as i have not played with that yet, But i do set the power target to max...

Not all cards overclock the same, some worse and some better. Try inching yourself up and see where you get

Thats for taking the time to reply! Do you know the ratio for adding core clock/ Mem clock? From what i have learned so far i dont want to in cress my Core clock to much...

Thanks for the reply mate! I am more that happy to test this out, It would be a bit more simple if i had a sort of ration for adjusting core clock/mem clock. Sorry if this sounds a bit stupid but I am a newbie to Overclocking =)

Not sure it makes much of a difference, that said I've not looked into it. I push +140Hz to my clock and about 180Mhz to memory. I can probably go higher on memory but from what I saw it had negligble difference.

Maybe someone with more insight can shed some knowledge on the subject

Ah i see. Anyway thanks for all the help mate =) appreciate it (Y)

BSOD's are frustrating and finding our best overclocks, we will encounter a few of them.

Patience is the key and don't go for big from the off. Like Deceptor said, Add a little at a time and then run a loop of Heaven. If it passes, add a little more and repeat. When it fails, drop back 2oMhz on the clock and rerun Heaven for around 3 loops (cup of tea time). If all is good, go and play some games. If it crashes, reduce by 20 again and play some more games. BF3 is demanding on the GPU, so worth playing something like that.

Edit:

My advice is to do the Core overclock first (find your top speed). and then move onto the memory overclock. Same scenario as before but this time, you will see disco lights/black triangles/tears over the screen. This is the memory clocked too high and back off till you no longer see these artifacts.

Looks like its going to be a long day Hah, Im not much of a Fps man myself, I'm sure games like FarCry3, Borderlands 2 And DayZ will produce the same effect? =)

 

[Gregster]

Far Cry 3 for sure (I am sure Far Cry 3 is a fps as well ) I did edit my post and take your time is the best advice I can give

Edit:

Actually I am sure all those games you mentioned are fps's

 

[Deceptor]

You should grab Unigine Heaven benchmark OP (it's free), makes testing a lot easier. I run it in windowed 720p while messing with the values so I can tweak AB in real time as the benchmark runs (plus you get to see the impact in real time). Plus heaven can be fairly good at catching issues games may not.

The games you've mentioned though will be great to test out after heaven passes to be 100% sure. But yeah It's a time sucking vortex but worth it

Hey
My normal overclock of 1270mhz 7000mhz is on custom bios that give me more voltage

On my friends asus 660TI card he runs
1046 which boosts him up to 1246
6930 memory

Asus actually have released some new bios for the 660ti so if yours doesn't already have the new bios on you would gain an extra few frames by updating but I didn't mention it before as you said you wasn't interested in any bios changes.
The bios for the asus cards are all legit released by asus
http://rog.asus.com/158612012/graph...gtx-660-ti-bios-drop-inbound-for-performance/

With your memory at 6700mhz you will get a good 10 frame increase in performance on games like bf3 1080p 4xmssaa.

The gains made on overclocking video cards can be so minimal as not to be worth bothering with I'd take a look at the actual gains in games before deciding to stick with an overclock as to me a 5 fps gain simply isn't worth the potential instability.

From what I have seen with my own testing and looking at reviews the minimum you get is an extra 5fps at 1080p and other games are a lot more.

The actual performance increase can be as much as 15 percent and my friend who has same asus 660ti card got a massive improvement on 3dmark11 went from 9050 stock to 10250 overclocked.

There is some reviews below of the sort of improvement you can expect.

Not really sure what to make of the clocks in this one below

From personal experience I can tell you these 660ti cards run a lot smoother with a memory overclock and have far less drops in frames and as long as you keep your overclocks sensible then it will always be 100 percent stable.
