Insane OC on IPS screen

So this simply baffles me to no end.

We all know that IPS screens are not as OCable as TN panels. I OCed my 60hz TN panel on my Clevo to around 86hz until it gave up, which I considered a decentish OC. I've seen people push their TN panels from 60hz to even as high as 95. However.....

I decided to overclock my IPS screen on my trusty GT72 and I got way more than I ever could imagine. Yes boys I got this:

Spoiler

The highest I could run without it doing a messed up picture was 108hz.

MSI did invest in a hell of an IPS panel. This is the first time I've seen an IPS panel get pushed to this ridiculous extend.

 

Was able to push my Samsung PLS panel to around that or higher than that. It’s 15.6” and those aren’t known to overclock as well. I am willing to bet that isn’t an IPS panel and is actually a PLS panel. What is your exact model #?

 

It is an IPS panel!
LG Philips LP173WF4-SPF1

Pretty sick panel

 

If their televisions are anything to go by, LG make some great displays.

 

Same panel, can only get 71Hz stable, 72Hz starts to be fuzzy, 73Hz can induce epileptic attacks

 

What notebook?

 

MSI GT72 2QE, when I test fitted a 1070(borrowed to see if it would work, before all the talk about them) last year it also only went to 72Hz, so either my eDP cable is sub-par or as usual I got crappy silicon.

 

I got the same notebook, mine runs at 108hz lol

Try and update your BIOS.

 

Already on latest BIOS, VBIOS and EC, same results with and without modded VBIOS.

 

This is so odd. I got a slighlty different model, I got the 6QE. However, when doing latest BIOS, my monitor would run stock at 75hz. Are you sure you got the same panel and not another version of the panel? Because I highly doubt MSI would force all panels to run at 75 via BIOS update while some monitors can't reach that.

 

The 6QE is a bit different, different BIOS, different chipset,maybe its a revised panel,

LG Philips LP173WF4-SPF1

Build date: 2014

Can be a revised pannel, because your laptop is newer than mine.

 

Mine is:
LG Philips LP173WF4-SPF1
Week: 0, Year: 2014

So Nope.

 

RNGesus again..

75 Hz is ultra fuzzy, 90Hz kills the display, the backlight flashes and I have to force shutdown lol.

 

I think this is wayyyyyyyyyyyyy beyond RNGesus. I mean from barely 72hz to 108hz on the same model seems WAY to big of a stretch.

 

I'm just lucky like that lol.

The 630m in my old old laptop could OC like 40Mhz, a friend of mine could push his +300Mhz on the core and something silly like 350-400Mhz on the VRAM.

 

@Danishblunt is your laptop G-Sync enabled?

 

No. I got a model where the 980m doesnt support gsync. Monitor does however.

 

You got me thinking..

Both my internal display my external one both show the same lines/blurr at 72Hz, humm..

What is your VBIOS version @Danishblunt?

Can you run GPU-Z and take a print?

 

I modded the vBios. So even if u got the vBios version it wouldn't do you any good.

also thats really strange. Do you have a gsync card?

 

More or less, my GPU shipped with some VBIOS and I then updated it to another version when MSI put it on their site, due to some compatibility crap, and I flashed it a long time ago.

I also have a modded VBIOS, but I dont like it, maybe I should try it again, it behaved strangely, but that might be the effects of Dragon Center and other programs messing around, the GPU would only boost the clocks when I press the Fan Boost button lol.

I just wanted to see what is your current VBIOS version, mine is:
Version: 84.04.22.00.0A
Release Date: 2015-06-26

Techpowerup says that there is also this one: 84.04.48.00.20

Nope, no G-Sync here, its the Dominator Pro model.

 

Mine is 84.04.48.00.2A

 

My older GT80 screen was overclocked from 60hz to 110hz I usually kept it at 100hz though, but yeah some screens are very overclockable. That overclock is insane.

And then some screens are awful at overclocking. My current Lenovo P51 I managed to overclock from 60hz to 64hz before crashing haha.

 

My GT70 went from 60 Hz to 72 - but with flickering pixels, no use.

 

I've found you can get a few extra Hz out of screens by manually editing timings. The front porch and sync width numbers are old relics from the CRT days that do nothing except reduce refresh rate on LCDs:



So reduce the front porch and sync width to 1. This then lets you lower the horizontal and vertical total pixels, reducing the pixel clock, allowing you to raise the refresh rate. This got me 2 more Hz over the automatic settings.

 

Where did you get it?

Cant find that version anywhere :/

If its a 980m, and its non G-Sync, could you send me a dump of your VBIOS?

I wouldn't mind to try it out.

 

The vBios was stock like that on my notebook. I can dump it, however it's modded as I said, so it can cause a black screen or even kill your card.
Can you make a screen of GPU-Z?

 

Some complex hex-edit thing, or just Maxwell Tweaker?

If the second, I can revert it back to the values on mine, and test it.

If it is indeed the Dominator Pro and not Dominator Pro G, I think G-Sync VBIOS dont like to be flashed into non G-Sync GPU's, but there is always blindflashing lol.

 

It is dominator pro g, however they messed up with the card, it's non g-sync, hence I have no g-sync options. So if you have a non g-sync card then you should be fine. After some research you should be fine with my vBios, worst case you'll get a black screen in gaming.
I'll send you a dump in a couple of hours when I get home.

 

When I get home I will also post a print from GPU-Z.

Thanks!

 

Here is the print form GPU-Z:

 

No issue with blue color when overclocked?

 

Oh god I completely forgot this thread! I'll dump that vBios later and send it to you for testing today.

@Alex
nope, everything fine.

 

No darker vertical lines on solid blue backgrounds? I've got *-SPD1 which also can be overclocked to around 100 Hz, but it results in said lines.

 

Nope. no weird lines or similair.

 

Hi, I didn't want to bother you, so I didn't ask you again, because I tough I was already pushing you.

Could you run GPU-Z and post a screen, just to make sure that the GPU's are kinda similar before I flash your VBIOS?

Best regards.

 

Here you go buddy.

 

Panel over clocking is a very panel dependent thing. The same panel on my P870Dm-G 2 years back could do 112Hz, but in a friends system from 6 months back could barely do 78Hz. None of this depends on the vBIOS or the system BIOS itself. Its the panel binning of sorts.

 

But isn't this kind of extreme? I mean jesus 78hz or 112hz that's quite a difference.

 

I'm giving it the benefit of doubt because my (not gaming, and not that great) external display(VX239H) also craps out at 72Hz just like my internal display, thats why I'm a bit curious if there is anything VBIOS related.

EDIT:

@Danishblunt Your GPU is the 4GB VRAM, mine is the 8GB version, thats why the VBIOS version is a bit different

 

If it's the 8GB variant, then why not try premaBIOS?

 

No ideia where to get such VBIOS, and he doesn't touch MSI stuff, I have one from Svet, but no different on the display OC.

 

Not really. These overclocks on that panel ( and a few others are very very common) , there have been quite a few threads and discussion about this in the past.

Nope, thats already been tested way back. The vBIOS doesn't have anything to do with it. Since the OC entirely depends on what the Panel/Controller can handle.

 

Thanks, neat information really.

 

I was able to set my 120Hz TN panel in my ge72vr 7rf to 135Hz with cru and manual timings. Working now on achiving 136Hz
