Question what is rx 580 actual memory speed

[M Sajid]

i am using sapphire nitro + rx 580 4gb but i don't know the memory speed ot this gpu correctly because in some graphic card the clock speed has written 1750mhz and some graphic card the clock speed is 2000mhz.why is this?

Those are just different variants of this same GPU from Sapphire. Few models have been slightly factory overclocked than others. There is nothing to worry here. Check the following database links, and under the exact SKU/MODEL number of your GPU, check and compare the Official specs with your card:

thanks for informing me,i didn't know this before,i found my gpu model which is sapphire nitro+ rx 580 4gb (sku# 11265-07-41G) and i saw that all 8gb version is 2000mhz and 4gb version is 1750mhz,mine is 1750mhz,now i have a question for you can i overclock it 1750 to 2000mhz?

Yes, you can OC the MEM frequency, but it's not worth doing all this. Only few games might benefit from an OC'd Mem clock speed, not all. Overclocking the GPU CORE freq might be beneficial though, to get some extra FPS while gaming, but is it really worth doing all this, this you need to decide ??

Also, you need a decent quality PSU as well. What's the make/model of your current power supply. Here's a short guide made by me, on how to OC the GPU. This is just for reference though.

""You need to OC in small increments first, and check for the system/GPU stability.. Try to not increase the frequency higher than 5% on both the core and memory clocks. Example: suppose if your card runs at 1500 MHz, then you shouldn't increase the frequency any higher than 25-50 MHz. If the system is showing artifacts, polygons, and/or it freezes, then you need to dial down the speed in small increments, like e.g. 25 MHz.

Start with 25MHz. You need to observe at which frequency the GPU gives you a stable result. OC can be risky, if done incorrectly, so be very careful when overclocking.""

For the system stability, you need to look for artifacts, polygons, or a system FREEZE/hang after applying the overclocking settings. If you don't observe any of these, then you are safe. Voltage and heat are the things you want to watch out for. Only increase voltage if your temperature values are safe at FULL load. All components have different voltage tolerances.Voltage increases should always be tiny.

The basics of overclocking:

• Increase Mhz
• Test (Prime95 or Heaven, or any other benchmark for ~5-10 mins)
• Repeat until it fails.
• Lower Mhz OR increase voltage
• Repeat.

Once you have your maximum stable core overclock figured out, you can do the same for the Memory. Now, memory OC's generally don't provide that much FPS gains, so it's up to you if you even want to tweak this setting as well. You use the exact same process as your CORE overclock, and take it as high as you can.

Move the Core slider up 25-50 Mhz. Run Heaven for 5-10 mins, watch your temps, etc. It's the same as CPU overclocking. Once you get a driver crash, system freeze, or see visual anomalies, then dial it back to 10-20 Mhz, and then try again.

The clock speeds vary with every model. Those values are normal. Which power unit do you have ?
