RE: Custom Resolution Utility (CRU)
I can run native resolution at 144hz (1920x1080) but when I add a custom resolution which is 1440x1080 it only works at 60hz and if I put it higher I get out of range on my monitor?

EDIT: When I use CRU and add a 1440x1080 at 144hz, I get out of range on my monitor if I select it in windows but if I add the same at res @ 120hz in CRU it works fine and then I use windows to switch from 120hz to 144hz and then it works still? Is that actually 144hz or is windows lying to me and its 120hz?

RE: Custom Resolution Utility (CRU)
Hi guys! I have a problem about idle memory clock.

At first page, it says "AMD/ATI cards require the "LCD standard" vertical blanking/total to reduce the memory clock when idle." I have a Sapphire R9 290 Tri-x and even I use LCD standard, my idle memory clocks are not lowering to 150mhz.

Anything above 70hz monitor refreshing rate causes idle clock to be 1300mhz instead of 150mhz. Choosing LCD standard or reduced doesn't make any difference.

How can I solve this problem?

^ me too, always been the case (7970 original). I manually downclock when doing desktop work in order to avoid the noise and heat that's otherwise caused by this. Never found a way around it

RE: Custom Resolution Utility (CRU)
Hello,
when I set custom refresh rates in CRU they don't show in the control panel. I'm using HP Pavilion Sleekbook 15 with Intel HD4000 and Nvidia GeForce GT630M. Could anyone help me? I play a lot of Counter-Strike, so 75hz would be helpful (native is 60hz)

You might have to manually increase the vertical total a little higher for the R9 290 cards.

The 7970 shouldn't have this issue. The only other reasons the memory clock wouldn't be reduced are if you have multiple monitors connected or if video acceleration is active.

The monitor doesn't support 144 Hz at 1440x1080. Enable GPU scaling to use 144 Hz at lower resolutions. The 120/144 Hz switch is probably a monitor bug.

RE: Custom Resolution Utility (CRU)
Okay, here's my issue. I tried to use CRU to add lower refresh rates for better video playback (monitor is a HP w2408h connected via HDMI with a HDMI splitter inbetween, video card a R9 270X).

I added 1920x1200@50hz, and it worked perfectly (as opposed to the broken 1920x1080@50hz that the monitor sort of supports by default).
Then I added 1920x1200@48hz, and it, too, worked perfectly (as reported by madVR and ReClock).

Then I decided to mess around and added 1920x1200@70hz, but of course it wouldn't do that, so I deleted it again.

Except now it throws up input signal out of range errors when trying to switch to 48hz (50 and 60 still work).

How can that happen? It absolutely did work the first time. Tried with both LCD standard and reduced, also tried 1080p48, but that didn't work, either. Am I just SOL here and broke it somehow?

Either you used different timing parameters the first time, or 48 Hz is at the edge of what the monitor supports, so it only works sometimes. There isn't a 48 Hz standard, so you might have to use the 50 Hz timing parameters. Use "LCD standard" to get the 50 Hz timing parameters, then switch to "Manual" to change the refresh rate without affecting the other parameters. The totals should be 2640x1125.

You can also try the 60 Hz timing parameters, which should already be in filled in when you click the "Add..." button. The totals should be 2200x1125.

That was fantastic advice, I got it to work at 1920x1080 with the 50hz timings and at 1920x1200 with the 60hz timings.
Now you're making me wonder whether I accidentally set it the first time with manual with the 60hz paramaters already filled in, but either way, it works now, so thanks for the help!

I owe you a couple of beers, this tool is really helpful Smile
