Asus 750Ti overclocking help with GPU Tweak

[weirdzaid]

Ok so, i know nothing about overclocking, and i have read the guides but still confused.

I have an Asus 750Ti 2GB Graphics card. I want to push the card to the max without hurting stability. No cooling besides what comes with the case , i have a thermaltake commander case.

The default i see on my settings are :

Gpu boost clock : 1150
Max Gpu Volatge : 1168
Memory Clock : 5400
Power Target : 100
Gpu Temp Target : 80

The furmark thing keeps blinking, and when its done gives me a score , etc.

Now i have been running furmark benchmarks. But i don't know what " if the benchmark passes, then increase until it fails. " how do i know if it passes or not? What does passing mean ? Specific temperature?

Basically after each time i benchmark i get a specific score. Nothing tells me if that's passing or not.

Another question , what's an acceptable gpu temperature? What should i not cross, what is safe? Etc..

Really appreciate

Also very unrelated question

I'm running 750Ti , I7-4790 , Kingston 8gb , WD 1TB , Gigabyte h81 , thermaltake case . And i'm using a 450w power
supply, is the psu too little? i was told 450w would be sufficient since the 750ti is a maxwell piece and its requirement is very little. If it's too small and is making pc performance weak , recommend a psu please. Thanks again!!

Hello weirdzaid,

The 750ti calls for a minimum of 300 watts so you have plenty if you are just overclocking your gpu.

If it finishes the benchmark without crashing, your machine passed.

An acceptable gpu temp is anything up to 80c, no more than 85c.

To overclock your 750 ti to the max:

Crank up the power target as far as it will go and start with the core clock, keep slowly increasing it until the benchmark fails, then just back it down a notch to where it passed. Then start with the memory, keep increasing the memory speed until you start to see artifacts then back it off a notch until the artifacting stops. That's pretty much it.

Hi thanks a bunch for your input! My furmark keeps flashing ( Even at lowest settings ) , i tried heaven unigine though and worked a bless, and saw improvements the higher i went, is that fine?

And regarding PSU , if 300w is only for the gpu, is 150w enough to fuel the rest of the computer ? processors, drives, usbs, etc?

300 watts is the minimum psu for your entire pc.

Are you saying furmark is flashing with stock gpu settings? If it runs Heaven ok, you can keep raising the core clock speed until it crashes, then back it down a notch. Same with the memory keep raising it until you get artifacting then back it off a notch.

Do the core clock first until it crashes, then once you find its max you can move on to overclocking the memory.

Both of them went fine at max, clock from 1150 to 1285 and memory from 5400 to 5600, both together giving me 10 max fps more, 100 better score, just apply and done? No artificating ( dont know what that is but there wasn't anything out of the usual ) and no crashing, thats with heaven , furmark flashing at stock gpu settings yeah.

Yes just click apply and that is all there is to it. Keep pushing the core until it crashes.

Artifacting is when you see little triangles and dots flashing on your screen. Keep pushing the memory too.
