Hi, gandalf,

Now our next step is using MSI Afterburner :D please make sure you can adjust your fan speeds manually from MSI Afterburner, Automatic fan speed wont work for us :D We will have to keep some aggresive fan profiles so that benchmarks won't bottleneck our OC process.


When you read enough and feel confident, please start with Memory Clocks. We will not mess with core voltages untill we start getting some crashes and freezes ;)

Memory Clock is the least important so, we should deal with that one first, then the most important core clocks :)

As for Nvidia's there is also a Shader Clock there, but they are usually linked to the core clcoks. The ratio is 1 core clock - 2 shader. if you have 100 core clock your shaders should be 200. As far as I know, it will adjust it itself when you increase the core clock frequency. So nothing to worry about.

And post me your Stock Core/ Shader and Memory clocks, so that I can check our progress ;)

Now, start with 10 mhz increments for memory clock. and after some 50 mhz increase, start stress testing. And continue stress testing with each 10mhz afterwards.

Do your stress tests at max. settings and at least for some 10 mins. And check for artifacts and freezes/crashes. You wont have such things till you increase at least some 150 mhz memory clock but, still it is always good to be prepared for anything ;) while benchmarking and stress testing, the memory clocks won't affect your FPS rates by any chance, it just decreases the time of chapter loadings, texture loadings etc. So nothing in game or benchmarking. See if you can reach your max available memory on stock voltage. Or just leave it at a safe place where there is no artifacts or so, its your call ;)

Anyway, when you start having artifacts and abnormal behaviours on screen, crashes, freezes, black stripes, etc. immediately restart your pc (use hard reset, for you may not be able to reach start menu on windows :D ) then go to MSI afterburner again and decrease the memory clock by 20 mhz. to be sure. Then run stress tests and some games again, to see if there is still any abnormalities. if not you are done with the memory clocks then we can move on with core clocks ;)


NOTE: Never forget to save your progress on MSI Afterburner to an available profile slot. After each succesful increase please save your clocks, so that you won'T have to deal with them over and over again.
And after like 100 mhz increase, please start playing some games too, because as I stated before, stress tests are usually decieving and can give false results regarding the stability of your gpu.


If your your core voltages is not shown or you cant get past a certain limit of frequency, then please go to your MSI Afterburner directory.

Find and open with notepad, MSIAfterburner.cfg

there scroll down till you see the following lines,

UnofficialOverclockingEULA =
UnofficialOverclockingMode = 0 change the 0 to 1. and there you go.
UnofficialOverclockingDrvReset = 1
AccessibilityCheckingPeriod = 0
UnifiedMemoryUsageMonitoring = 1


I think they managed this issue in the new versions of MSI Afterburner but, still if somethings happens of that sort change the cfg to 1 and everything shall be fine :)


See you,
Waiting for your update,
Take care

Hey John,

here are my stock settings:

Core voltage: 987
Core Clock: 810
Memory clock: 2004


I got my memory clock running stable at 2500mhz. I tried maxing it out at 2605mhz but as I launched bf3 it just froze so I did a hard reset and just put it at 2500mhz were it was stable, might could get a bit higher but im happy with it as it is.

It was stable on benchmark and BF3, Since I finally got Crysis3 I decided to play it and it crashed almost right away, so I down clocked it to 2401 played a while and it seems stable :)

Core clock is next, what should I do?

see ya
and thanks for your help :)

Oh sorry man :) hello again :)

It's been a while, I was pretty busy, I couldn't get to my pc recently :(

Ok, since your card is stable under C3 and BF3 it's great news.

Now the most crucial part,

Overclocking your Core clocks,

1) Start by increasing your core clocks by increments of 10 Mhz. Same rules for core too, around 50 Mhz or so, start benchmarking and playing games at every 10 Mhz. Do it strictly in core clocks, it is important.

2) This time, no stepping back from our clocks ;) When you reach a clock that your card is unstable, hard reset your pc, let a few minutes for the drivers to recover, then please increase the core voltage 2 times, with increments of 6 mV = 0006 V. In total, 12mV.

-Afterburner sometimes adjusts the voltage 12 -13 mV at once, so dont go for another bump, or it would be too much :)

3) Now, that we increased our voltages, your card should be stable now. Benchmark and test your GPU again. When you are sure there is no unstability, move on then :)

4) After you make sure the card is stable, continue increasing the core clocks by 10Mhz. Now that we passed the stock voltages you wont be able to OC your gpu as far as the first try, without increasing the voltage. So dont panic if you get crashes in every 20-30 Mhz or so, just apply the steps again.

5) Now, the most important part, you posted that you modded your gpu fan and you have good cooling system, there will be a limit of your GPU of course, where it will be unstable no matter how much voltage you feed it. But, reaching there means a lot of heat. As your clocks and voltage go higher, your temps will drastically increase. I recommend you to stop at a point where, your card runs about 80 degrees celcius max. At full load and with a rational fan speed. I did not heavily overclocked my GPU, because I hate the fan noise :D so a mild 150 Mhz core OC was enough for me, so that I can keep my card cool at 40-45% fan speed. But, if you are willing to listen to your fans and enjoy the performance of your GPU at a good OC :) then go ahead.

NOTE: Please check your temps especially after 100 Mhz. We dont want to overheat your card ;) And when you think you have a decent OC please run your benchmark stress tests for about an hour so, and play a lot of games for a good time. You are most likely to enjoy higher clock speeds then a stock 560 cooling system ;) Lucky for you to have those parts :D

Good luck man,
Update me on your achiements :) I would like to hear how bestial your card became :D

Sorry for the late post again, I got to you as soon as possible I hope it wasnt too late :)

Take care,
Good night :)

Hey John,

Nice to hear from you :)

Dont worry about taking a while to answer, Im glad u are helping me out.

Ok so I started playing around with core clocks, got it stable on benchmark (havent played games yet, will do in a bit) I also got a surprise score benchmark 1999.jpg

As for my gpu fan, that thing is pretty loud, lol, if i dotn listen to music, watch a movie or play a game I can hear it pretty loud, but once im in my zone, it doesnt bother me. I usually kepp fan speeds pretty low, when I game I usually put them on around 50% which is pretty loud if you dont have your headphone on, but thats my opinion... My wife hasnt complained or said anythig about noise and she has her pc set up in the opposite corner of the room, so maybe it isnt that bad (when on full power you can hear it down the hallway, lol) I think they are delta fans (at least gpu and cpu radiator fan),but im not sure 100%, all i know is they do a good jobon keeping temps low. During the benchmark max temps on gpu was 48 (with fans on full power)

Anyways, thanks for your help, I will see if in game it holds up and maybe ill try to push its limits just to see how far I can go ;)

Again thanks for all your help

Peace
Gandalf

Hey John,
Ok I played crysis a bit and it heldup well, no problems whats so ever :)

I tried going to a higher clock, got it working with out problems (didn play c3) but I got a lower score :/ idk why, so I put it back to the same setting as before and got a different score O_O is it possible that scores arent always the same?
ohh well, important thing to me its performance not scores..
let em knwo if I should try anything eklse, gottta run to work :(

peace

But your average FPS went higher from your last benchmark am I right? I remember some 25 FPS or sth else from your former benchmarks :) Well, try MSI Kombustor's benchmark with preset 1080p. The min fps seemed a bit low but, they may be deceiving of course. Keep on benchmarking and game testing if you experience dramatic FPS drops lower your OC.


Nice job, you did 950 Mhz is pretty cool :) But as I said if you experience dramatic FPS drops, lower your OC, because it means you probably reached your OC limits, try feeding some more voltage to the card, if not helps, just lower it, it may damage your card to keep in such an unstable situation.


Take care,

Keep me informed :)

And send me some MSI Kombustor benchmark scores, and lets see how many points it can score with that 950 Mhz :D
