Can my GPU be overclocked?

[Bullet4Justice]

Hello guys, i was wondering that if my GPU can be overclocked?

 

PC CASE: Vengeance® C70 Mid-Tower Gaming Case — Military Green

 

CPU: Intel Core i5-4430 3.0 GHz

 

GPU: Sapphire Radeon HD 7870 GHZ OC 2 GB 256 - bit GDDR5

 

RAM: Corsair Vengeance 8 GB (2 x 4 GB) DDR3 1600 MHz

 

PSU: COOLMAX RM-850B

 

Thank you for your time...

Yes you can. You can overclock it in amd overdrive

[Bullet4Justice]

Yes you can. 

 

How do i do that? and what are the best overclocking settings for my GPU?

No need to put everything in the middle of the post

 

Yes you can overclock it.

Yes you can overclock it.

 

I'm sorry, i'm not an expert at PC Specs so i don't know what the requirements to overclock a GPU

Ok, nothing wrong with being a newbie. I'm glad you chose this forum to start off your road to PC Master Race.

thanks, i love how detailed Linus videos are so i thought that this the best forum that i can ask on!

Oh yeah, other part.

 

Basically, overclocking is sort of luck. Your GPU may not overclock at all. Or it may be able to just go and go and go whilst still being stable.

 

Just turn up the GPU clock setting a bit. Maybe 900Mhz? Then run some stress tests and see how it goes. Just keep in mind more OCing equals more power consumption.

Also, remember that the increased clock settings will only be applied when in high performance mode.

is there any programs that i can use to test the new setting?

Upon changing something... TEST IT PROPERLY - Do not quit testing after 30seconds and seeing it run fine,.. you want at least 15mins or so testing because heat will pool inside your case, and you should always regulate your temps for longer uses (gaming for a long time) in regards to testing.

 

Uengine Valley (a few runthoughs of this)

UEngine Heaven (same)

3DMark software (same)

Your Games (Do NOT just rely on the above three synthetic benchmarks, but if its stable in the above 3, check your games stability too)

 

Most AMD cards 7000 series to current ones usually have an avg OC to 1050Mhz-1100Mhz *usually,....without any extra voltage added by you.

You can get more sometimes by adding voltage or watercooling your cards, aiming for 1100-1150Mhz on Air is pretty nice to achieve while keeping at eye on temps...

You may even get 1200Mhz on the core, but possible not.

Coreclocking brings WAY WAY more gains than MEM clocking, also do ONE at a time. Find your MAXCORE, then your MAXMEM while core at stock.

Then see if you can do both max's, you may not, so Keep your Core at its absolute MAX it can while pushing memory clocks as a secondary priority afterwards.

 

You may need to up the fanspeed profile, and you can use MSI Afterburner for that, as well as normal overclocking, to which I'd say not use Overdrive, and use MSI AB first. It has way more options and variables you can screenshot/record video with it also, have an on screen display of your specs and fps...

Youtube search MSI Afterburner Tutorials

Go slow, bit by bit, do not rush or take shortcuts, google/youtube search MSI/OC guides, do not copy another persons card settings, all cards are different in OC abilities, even similar models.

which is the best one of those?

Doesn't really matter. I like 3DMark but it;s up to you.

There is no best... there only are variables...

 

Some softwares that 3D bench, have different tests and such that push different areas of the card, this is why its best to use multiple softwares to test.

 

A test may be more memory bandwidth intensive, good for your mem-OC, some may be geometry bound, pushing your core clock, some may be post processing driven, pushing your shader cores,.. and some may do a nice mix of all... Games are a good indication of this, different technologies in various games..

You wanna know if its stable everywhere, this is how to know for sure.
