Overclocking your monitor refresh rate - AMD GPU's

[SkilledRebuilds]

Posted earlier...But to those that say its placebo...You have no F idea.

Did 60hz/65hz/70hz but I used 75hz, Works fine, windows IS smoother, games with vsync stay at 75fps and thank god, I hated 60fps and those dips below...

The info shows up in my LCD (NOT Windows, My actual LCD menu) Info where it shows that its currently running 1080p @ 75hz

If you think it doesn't work, think again,....you either have not tried it or you didn't do it right. Or your LCD is incapable.

Hey can i overclock my led monitor using cru (gpu: amd hd7870)

Hey can i overclock my led monitor using cru (gpu: amd hd7870)

Just as I described in my first post, most monitors these days are LED lit. 

[Alex(PlayMedium)]

I just need to be able to oc my mouse's sensor

you can overclock the report rate of the mouse up to 1000hz, but if you click the wrong things you might brick a USB port ^^

My monitor is native 60hz on 1080p, AMD Catalyst reads out MAX is 75hz at 1080p so i got my monitor up to 70hz 1080p with no problems!

I have a 24" Dell 2408WFP LCD monitor at 1920 x 1200 @ 60 Hz.  I tried the CRU program and added profiles for higher refresh rates, but when I switch to them, the monitor goes all fuzzy like it's at a lower resolution.  When I hit my monitor's "display information" menu, it says the input resolution is 960 x 1200 @ 70 Hz, but it automatically displays at its native resolution and refresh rate.  So it looks like the program is working, but unfortunately, my monitor seems to protect itself against settings it isn't used to.  The same thing happens when I use the EVGA Precision X to modify the pixel clock.  Unless someone else has a different idea?

just O/C'd my 1440p Korean monitor to 80hz

 

Pretty damned happy. One of these days I might just push the limits but for now I'm going to stick with 80hz.

Thanks for the awesome guide.

 

I wonder if this whole O/Cing of monitors thing is going to catch on and if we might one day see people watercooling their monitors to get the most out of them... It would be hilarious for sure!

i see no diffrence 60 vs 75. 25hz is enough for me

[Bluethulhu]

I went from 60Hz to 120Hz on my laptop. Night and day difference.

[Virgule]

Help! 

 

I misread the first step and deleted all profiles. Now I get the following message when booting cru : "no display found in the registry"

I can't boot cru. I downloaded my monitor's driver (samsung synchmaster 244T) and installed them and now my monitor is recognized in device manager and screen resolution window.

Got my Alienware 1080p screen to 85hz, my previous model couldn't get higher then 74.

 

First i thought could it be that they built in a 3d monitor but locked at 60hz, but 120hz didn't worked meh.

 

Gonna try 90-100Hz now.

[Virgule]

Can't even get at 70 Hz on my Syncmaster 244t. The display is all f*cked. I switched it back the fastest I could.

I don't know why but windows won't show anything above 80hz for me. 

I have 2 7950's and a 1440p korean monitor which should be able to get atleast 96hz after doing some research.

Hi, Yes, you will need to apply the AMD Pixel Clock Patcher for very high refresh rates at high resolutions to show. Note that it can cause some issues ( hasn't for me) and that you need to run it before and after updating GPU drivers (before to undo the patch and after to patch again) 

Also extremely high pixel clocks that 96Hz requires for 1440p require that you use 2 CrossFire bridges.

Not sure the reference applies but...Intel could sell stock underclocked 3570Ks at 1 GHz and people would start noticing it goes to 3.8GHz quite easily without any dangers. I think every device has a safe range of use even if this range exceeds whats written on the box. We only need to hear it from a qualified engineer.

No.

The way the processor market works (CPUs and GPUs) is that they work on the "Halo" model then cut down, and lowered clock for the lower-end models. In this case, the panel is deisgned for 60Hz, then you decide to push it faster.

It's like taking Nvidia Tesla GPU, they are the fastest graphic card possible, and you go "Let me push it even faster!"

For AMD there is some patch to do... look into it.

But also note that thet are no consitency with the Korean ebay monitors. They get components that is the cheapest as possible. So they have deal with a few suplier for the internal components, and each got different specs. So it's a lottery, unless you get the certified one, which you pay more, usually the price of a proper brand monitor.

My monitors say "Input Signal Out of Range" When I click on 70hz in the control panel. It basically makes the computer unusable because it covers up the center of the screen.

 

Any idea how to fix this?

[GoodBytes]

Hack the monitor firmware (if it's upgradable) is the only solution.

[bradscoolio]

ToastyX has also made a really awesome light boost utill, works brilliantly too I'd trust him do this pretty well also

[Purple]

Is it really worth it? 

[dadyal]

My screen worked fine at 1920 x 1080 @ 75hz and then i added a new  85hz after the reboot i can't screen the windows destop anymore and my screen is show this box saying

Not Optmum mode


anyone know a way to reset it back to 75 hz  or 60 hz ?? i am using windows 8.1 and this peice of crap don't boot into safe mode

[gigi1237]

I managed to oc my monitor to 75Hz but after running this utility I found out the monitor was dropping frames

[Camul]

I hope you guys know that you can do all this in the Nvidia and AMD control panel.

This is nothing new.

How do you do it in CCC?

[GoldSrc]

just guess who posted this before,anyways you need to patch dvi freq in order to get this working ,check my thread 

Would you mind telling me how did you patched the dvi freq?.
