valley benchmark questions

[Mr.Reggin]

So does valley benchmark also use a higher clock speed on the fly of the gpu while benchmarking when I have increased the clock with msi afterburner or do i have to restart the benchmark?

Is it a good program for finding stable overclocks?

[Archangel1994]

Changing clocks DURING benching is usually a bad idea since nearly every program does not take kindly to changing the speeds on something they are stressing heavily.

but it does change if i restart it, right?

Close valley > Change clocks > Open valley

 

Rinse and repeat

yeah thanks, just found that out, if i can run the complete benchmark without a driver crash, is it a stable oc?

I would test for a few hours straight, 3-6 hours would suffice but really usually when it's unstable you often notice it before the 3rd or 4th scene (in valley), I've seen crashes at the 11th or 15th scene but never a full successful 18 scene run and THEN crashing

So I just tried BF4 with +94mhz on the core clock and after 4 min it crashed, so I currently try it with +88mhz, i am doing that currently on my laptop and i cant increase the voltage, so I just see how much I can get without any problems.

using a nvidia geforce gt 750M 4GB GDDR3 :.(

I second this, you could just let Valley loop for 2-3 hours at the most and if you don't have a driver crash or artifacting then its stable once you hit your max though for Core and Memory clocks keep it 10-15mhz from the max to prevent driver crashes in other games or software that is using your GPU to improve performance.

I never recommend holding the absolute max OC because of things like this and 0 spike usage headroom.

what is artifacting?

what is artifacting?

All of these images are example of artifacting, its caused normally by a overclock being unstable but still stable enough to keep the driver from crashing and causing graphical anomaly's

[Archangel1994]

Those small blips are an example of minor artifacts. Now take this and apply it to your entire screen. You WILL know when you have artifacts.

okay

so i just played Battlefield for 1hour and 30 minutes with an overclock of +80mhz on the core and +150 on the memory and i didnt have a crash.

games are the best thing to test for stability - Valley has a rock solid engine and I get much higher overclocks in valley than in anything else. I can do 400mhz higher on my ram in valley than I can in COD:AW - and 30mhz higher on core than in 3dmark.

 

If you get a crash in a game just drop the overclocks by 10mhz and repeat untill no more crashes.

just had to drop it to 75 on the core 135on the memory. i still get 2

7% more fps in valley
