R9 270X, does it oc?

[Franker]

I have a Sapphire R9 270X 2Gb Dual-X OC card and have several times tried to overclock it. 

 

When i overclock the card i get worse score's in benchmark software's and worse performence in games.

I've tried a bunch of different oc settings.

 

I have oc with, and used:

 

AMD Catalyst and Sapphire Trixx. 

 

3D Mark Firestorm, Furmark and Cinebench.

 

I've notice performence drops in pretty much all games i play.

A few examples are:  

 

Arma 3 (major drops)

Battlefield Hardline

Far Cry 3 and 4

War Thunder

Eve Online 

 

What am i doing wrong? Or do i have a "worse than average" card?

 

PSU - CM 550w 80 bronze

Gigabyte 970A-DS3P

AMD FX-6300

one problem i see

 

that PSU is not a great PSU to begin with

 

if you OC it puts more load to the PSU and it may get power loss = lower fps

 

also is your CPU OCed?

[Tim Drake]

Btw the reason you get huge drops in Arma is arma HAAAAAAAAATES Amd cpus.. Because their single core performance is pretty god damn bad..

That PSU should be fine, a 270X doesn't use that much power. It might start throttling because of the higher temperatures though, although that also seems a bit unlikely as it is a dual-X card. What are your temps?

[Franker]

Cpu is OCed to 4.7ghz with NZXT Kraken x61.

 

In Firestorm and Valley temps hover around 65-75 degrees, with and without OC.

In Furmark it goes to 82-85 degrees with and without OC. 

 

I have noticed in Furmark - On stock clock (1070), the clock stays there. While OCed and monitoring with GPU-Z the clock drops tp 1060 for the majority of the benchmark.

Adjusting volts seem to have no effect at all. Tried unlocking the volts with MSI Afterburner and EVGA Percision but with no success.

 

Benched with Valley using Afterburner a few minutes ago and got the drivers to crash at 1145mhz and there seems to be nothing i can do to stablize that clock or increase to OC.

It's a cooler master 550W PSU. It's plenty.

Depends which Cooler Master 550W PSU it is. Cooler Master has some real stinkers and some great PSUs.

Its the G550M

Have you checked for a CPU bottleneck? Running software such as MSI Afterburner has a CPU overhead. If you are CPU bound, FPS will drop when you start running additional software; especially if is constantly updating things on the page.

Ehh i guess i havent. How do i check for a CPU bottleneck?

 

Im kinda new to this.

Is there really a risk of bottlenecking with a  4.7Ghz 6 core?

It's not great, but it should be fine for your system. So I would look at CPU bottlenecking, GPU power limit, driver problems etc. first.

I'm no expert in this area. I can't say I've ever owned an AMD CPU. I gather there are some issues with the FX series and bottlenecking. I'm pretty sure my friend is bottlenecked in BF4 with an FX 8320. Check your CPU loads in task manager. If it's >90% there is definitely a bottleneck. I don't know about AMD and Hyper Threading or similar, but post back with CPU loads in games and I'm sure someone here will know.
