V-Sync On vs V-Sync Off

[Acerpwns]

so i just installed my new GPU and before i get into overclocking i wanted to run some benchmarks. i started with Unigine Heaven. this is with V-Sync off

Unigine_Heaven_Benchmark_4.0_20141231_1323.html

 

so apparently the benchmark with VSync didnt save but the score was 839 Min fps was 20.5 and max was 60.1

 

 

 

EDIT: Lol im so tired i forgot to actually ask a question, i know what V-Sync does but i dont understand the diff in scores

VSync locks the framerate to the refresh rate of your monitor (Usually 60, 120 or 144Hz) meaning that the amount of fps never exceeds what the monitor can output to prevent screen tearing. This introduces more input lag though which is the downside

so V-Sync=bad benchmarks

Not necessarily but in this case you are limiting max fps and therefore reducing your score. Bench without Vsync to get your "true" score.

 

Also something is not right in your PC because I get 2650-2750 score in valley with a 970

He is running heaven not valley. Also your valley score is also not that good my i5 4440 and zotac 970 (at lower clock speed) got around 2700 ish.

[Archangel1994]

He is running heaven not valley.

Oh durr, I'm an idiot. Still isn't the 970 supposed to get around 1700 there?

i have no idea whats wrong, im gonna run valley now

[nhatduy1611]

Nope a 970 will score around the 1400-1600.Mine got 1476.

Still a bit on the low side or have you not overclocked yet?

That's pretty good since it is at stock.

On the first post he said "just installed my new GPU and before i get into overclocking i wanted to run some benchmarks"

[Acerpwns]

nope, just making sure it actually works stock first and tbh im not too familiar with GPU OCing, not sure how it works really. CPU no problem, GPU ehhh...

[Acerpwns]

isnt the mem clock for the 970s something around 7 Ghz? 7010mhz i think but in valley it was only displaying 3505mhz for memory

[Archangel1994]

Valley displays it like that and most other tools to. 3505 is correct

[Acerpwns]

okay.... so whats the 7010mhz deal?

[Archangel1994]

Double the 3505 and you get the correct speed, don't worry about it

oh lol, so when you overclock a GPU using Afterburner what sliders do i have to play with? just Core Voltage,  Power Limit, Core clock and Mem Clock?

[Archangel1994]

oh lol, so when you overclock a GPU using Afterburner what sliders do i have to play with? just Core Voltage,  Power Limit, Core clock and Mem Clock?

Yep

 

- Max out power limit

- Voltage at stock

- Core 1500

- Mem 7800

 

Use this as a starting point, I have 1550/7800 at +18mV

If you are new to overclocking watch some video on it like this one made by linus and austin evans 

and https://www.youtube.com/watch?v=gA_l5-HDel4. Also not all gpu can get the same clock and memory speed so don't take someone clock speed and just applied it to your card be patience and careful it take quite a bit of time to make sure everything is stable.

What if you have a 144hz monitor but dont have a powerful enough pc to get those 144fps?

Then you've basically wasted money on something you cannot achieve

i know the general rule of thumb, i just never OC'd a GPU before. CPU, no sweat.... GPU, ehhhh. but thanks

What about the V-Sync? Does it even work?

[Acerpwns]

Yep

 

- Max out power limit

- Voltage at stock

- Core 1500

- Mem 7800

 

Use this as a starting point, I have 1550/7800 at +18mV

so what i tried doing was pushing the mem clock and core clock until valley wouldnt run and at a certain point i got an error message saying that the driver couuldnt load an OpenGL artifact (without touching the core voltage) and then when i added 10 mv i got a worse score in valley

Then the OC is not beneficial, it happens, did 1500.7800 work though?
