Sapphire RX470 flashing to 570 any benefits?

[BlaezaLite]

4GB Sapphire nitro + OC is there much to be gained from flashing to the same 570 model?

 

[BlaezaLite]

Bump for some general advice?

Faster stock clocks and power limits. etc

 

[BlaezaLite]

I'll try it and see what happens...

Ended up with a sapphire rx570 pulse that oc's very well.

 

[BlaezaLite]

Would anyone say these are good gains? 1236/1750 to 1375/1880? Doesn't seem to be much of a jump to me but I'm still noobing and messing about.

Any improvement is a good result. Some people haven't had much luck.

 

[BlaezaLite]

Did something good, yay!

Some RX470 cards used identical PCBs and coolers to the RX480s, and these were usually good for 1350MHz if you didn't mind some extra fan noise. The fact you have 7GHz VRAM on your card by default means that you likely have one of these.

For what it's worth, the Polaris cards undervolt almost as well as they overclock. You can probably use the AMD drivers to set 1300MHz at 1000mv which will give you 95% of the performance at inaudible fan speeds.

It has been a while now but I sampled several RX480's from work and stole/swapped my personal RX480 for the best example - it was running 1275@ 925mv and barely broke 75W. I also pilfered the sexy XFX alloy backplate from one of the cards so I was extremely pleased with my undervolting + corporate theft escapades.

Are there any extra shaders or memory to be unlocked for the 470? Just seen a thread about 560D.

So I basically have a 480 from what your saying? I'll have a go at undervolting, thanks for that. Mine doesn't have a backplate or any switchable bios, meh. Lucky fecker to have access to so many! But mine was £60 with years warranty, bargain. https://www.techpowerup.com/gpu-specs/sapphire-nitro-rx-470-oc.b4205

No, the shader count is hard-coded on those I think.

I'm saying your PCB, power-delivery, and cooling solution are likely identical to the Nitro+ RX480, so you shouldn't have any problem bumping up the power as far as it'll go.
Your GDDR5 chips aren't the same 8GHz variants as those on an RX480, and your GPU is fused off at 2048 shaders, but those are pretty much the only differences.

From what I remember the Polaris-era Nitro+ cards had decent coolers so you may not need to undervolt, but if you're even remotely concerned with noise levels, it won't hurt to try. You can do it all from the Radeon control panel, and use something like OCCT in the background to give you a full-load test with error-checking on the fly.

Well it's been running fine so I'll not push it.
I see, will have to just try to get cheap 580 when everyone flogs them for RDNA2.
Thanks for helping out.

have you tried setting your memory to 2000mhz? it usually will go that high. past 2000mhz does not yield any real benefits so dont bother. use hwinfo to see if you get any gpu memory errors.
