Overclocking the HD7970 GPU with a 550W power supply.
Overclocking the HD7970 GPU with a 550W power supply.
Hi there, I received your direct message and will respond here so others can understand. You might be able to increase the GPU power limit to 20%. If you proceed with this and also want to boost your CPU (which should improve gaming performance by roughly 5-10fps), it’s best not to raise the CPU voltage during overclocking. You should reach around 4.4ghz using the stock voltage of 1.368v while staying within your power constraints. Avoid running at exactly 550w as it could strain your PSU and cause future issues.
You can likely add about 50-100mhz to the GPU core and 100-200mhz to the memory, depending on various factors such as whether your GPU is already overclocked from the factory.
You can utilize this website to determine the wattage of your setup. The calculation wasn't accurate because the post lacks essential system details.
The results suggest your system might reach up to 400 watts. I think you could safely overclock your GPU, but be careful not to exceed power or voltage limits.
I wouldn't suggest trying to overclock both CPU and GPU at once, as that would likely cause issues beyond 550 watts.
This site can help you determine your system's wattage. Unfortunately, I can't complete the calculation because your post lacks necessary system details.
According to the information you provided, your system might reach up to 400W. You could try overclocking your GPU, but be careful not to exceed power or voltage limits. Overclocking both CPU and GPU together would likely cause issues since it may surpass 550W.
Here are your specifications:

Do you think a 20% increase in power limit is possible during GPU overclocking?
Thanks again for the assistance.
the xfx pro 550w offers strong power delivery and provides ample wattage as long as you avoid excessive overclocking on both the cpu and gpu... for instance, running at 5.0ghz and 1250mhz for each would likely keep the total system around 550w. Pairing your [email protected] with the 7970@1100mhz will also work well.

the xfx pro 550w offers great power and you have enough wattage unless you push both the CPU and GPU to extreme speeds. For example, running at 5.0ghz and 1250mhz would likely bring the total to around 550w. Using your [email protected] and the 7970@1100mhz should work fine. Would it be possible to raise the power limit by 20% during GPU overclocking? Also, could you overclock your memory? You didn't mention it. Thanks.
Hi there, I received your direct message and will address it here so everyone can understand. You might be able to increase the GPU power limit to 20%.

You can likely add about 50-100 MHz to the GPU core and 100-200 MHz for memory, depending on various factors such as whether your GPU is already overclocked or if you have a high-quality chip. The potential FPS gains from these adjustments could be up to 10%, with CPU overclocking also offering similar improvements, though to a lesser extent.
Regarding memory, overclocking is more challenging. It’s better to use the XMP profiles in your BIOS that adjust speeds (like 1333, 1600, 1866, 2133 MHz) and you can usually increase one step if you’re lucky with stock voltage.
