R9 270 Overclocking

[Camcognito]

Alright, so I downloaded MSI Afterburner and Ungine Valley, and I am ready to start overclocking my graphics card. The only problem is, I dont now where to start. What values should I increase in MSI Afterburner, and by how much should I increase them at a time? I've never done anything like this, and I don't want to ruin my card. Thanks

Core Clock MHz -> +50 first time, +10 second, and so on. If it gets unstable -5Mhz.

Memory Clock MHz -> +5.

Power limit + Core Voltage -> Don't Touch.

Change your fan speed curve.

how will I be able to tell if it gets unstable?

Artifacting, crashing, AMD Drivers have crashed.

-stares at your psu-

yea... i wouldnt overclock on that

but thats just me

[tahmidkhan123]

that psu isn't the best of ocing. I personally wouldn't ...

[Camcognito]

Is my psu not safe for overclocking? I'd made a thread about it and someone said it was. If not thats fine, don't want to ruin my pc

corsair cx series psu s are not the best out there, very budget units. I'm using one myself but a higher wattage one (600w). I've got a mild oc on my gpu but because my psu exceeds my required wattage, I'm comfortable with it. I feel that you are already near your 430watt limit with your current hardware. I personally woudn't risk, especially for the minimal gain.

Well I woudn't overclock with the PSU you have currently. You should go and get a better power supply;preferabally a EVGA G2 750w.

some may argue its safe

some may argue its not

 

my opinion is, just do it if you want. your card and cpu isnt that high wattage consumption anyway

 

but i personally wouldnt do it because im a chicken

[Camcognito]

Alright, I won't overclock. I'll probably buy a new psu, as well as maybe another motherboard and some ram. thanks for replies!

that would be totally unecessary... and overkill

something like a seasonic S12II or M12II 520W is more than enough for an i3 + r9 270

I don't really struggle for the extra performance at the moment, so I'll just say safe...                             for now

the best way to find out is just ask @STRMfrmXMN whether its safe

i would say it is safe, just that i wouldnt do it, but what do i know

Should be safe.

well since STRMfrmXMN gave the green light

 

here's a guide on how to OC

it's not a great guide but it covers the basics

if you have any questions then you can ask me

Skimmed through it, seems pretty easy. One concern I have is by what increments at a time do I change the sliders, and how do I know when I've gone too much?

mmm

here's my overclocking guide

Spoiler

for msi afterburner:

you can slide the voltage and power limit to max if you're comfortable with it, or leave them untouched

 

then increment your coreclock by 5 or 10, depending on how patient you are

and run your stress test for 5 minutes, if it doesnt crash, raise the clock speed again, i normally run one round of fire strike

repeat until your system crashed or you see artifacts, reduce the clock speed by 20, and slowly overclock the memory with the same method

 

after you found the stable core and memory clock, do a long stress test (i use unigine heaven) for about 1 to 4 hours depending on your patience, the longer the better

and if it crash or produce artifacts before time is up, lower core and memory clock by 5 or 10 and repeat

 

after long stress test, run games and test from AAA titles to low gpu usage titles (i use tomb raider, assassin's creed and starcraft), see if it crash,

if it crash, lower the clock of both core and memory again by 5 or 10

 

remember to monitor your temps and core and memory clock speed, see if they are stable or jumping around while you're doing all the stress tests

if it jumps around in the long test it means its not stable and you probably need to raise the core clock or the power limit, or temp limit depending on whats limiting you
