I raised my voltage for all my p-states, but 2d/state 0 of course, and forgot to put on my overclock earlier today. The computer was nearly unresponsive after a few min of sitting at the desktop. Also, when I change all p-states to stock maximum volts and clock, my screen blanks occasionally. Getting the right balance seems important on this card. If it's your 2d/state 0 though. Not much to do but RMA.

You can add a fake display, or add another connection to your current monitor tongue.gif

I actually tried fake display from Windows settings, but I noticed that it doesn't raise vcore/memory clocks unless the display is really on and receiving signal. Also if power off my 2nd display on extended desktop it automatically drops to single display voltage. There might be some way to cheat it though. biggrin.gif

So retailers charge a lot more for the 8 GB versions and i know it's faster but how much does that rly change performance.

the Sapphire Nitro versions are 1750 on the 4 GB and 2000 on the 8 GB regardless of RX 470 or 480 would that make the 4GB 480 a better option that the 8 GB 470 considering the 2-nd is priced higher biggrin.gif

What would the difference in performance be given same Core clocks and stock ram clocks

I was planning to wait for the MSI 480 8GB that has 6+2 VRM so they can have lower temps and have a quiet and more durable overall card but if it comes at 330eu it will be quite pointless to not get a 4 GB RX 470 Nitro for 230 eu instead.

The price / performance difference is huge

6+2 is overkill. On the reference cooler (terrible reference cooler from RX 480) the RX 470 I am using sees maybe 95c VRM temps when I have the fan speed set to be near silent (stock), this is with a 4+1 VRM. VRM temps with a mild OC (1300/1.120v) are under 90c once the fan settles into a steady state under load.

Even with 1.2v/1400 I don't see anything on the board go over ~95c, even the GPU temps are under 75c with the fan ramped up enough.

6+2 or more VRM's are a gimmick with this chip. 4+1 is good enough for anything you would ever get to under water. 6+2 would only benefit with LN2 maybe.

As for RX 470 VS RX 480 at same clocks, under 10%. RX 470 has the same number of ROPs, a few less TMUs, and a few less shaders. Since the design is primarily ROP bound, actual performance difference in games is 0%(ROP bound games)-12%(shader/TMU bound games). In the current games landscape it ends up around 6%, so you are better off spending 10%-20% less for the RX 470 if you can find one (especially with 1750/7000 memory). 8gb vram is mostly worthless at this performance level unless you crossfire.

Just couldn't wait anymore as I have completed a PC and it needed the newest Video Card model to finish it off.

Purchased this model from PCCG;

https://www.pccasegear.com/products/36440/msi-radeon-rx-470-gaming-x-8gb

Looking forward to installing it and using a Genuine AMD video card, instead of the Nvidia Product range (already have GTX 970s and 960s in use). The Last AMD card I purchased was a 280X model a few years back, so would love to see the performance difference with their latest model range.

I know lots here would boo me off for picking the RX470 but quite frankly, I wasn't looking for any stranger's approval but letting everyone here know that I support AMD's latest product range and am proud they still exist even today. Also here in Australia had to purchase the product just so I get a full and easy RMA process, if it's required down the track.

@Elrick

The only problem I see with that card is the memory speed. Might see what it will OC to, but from what I remember the memory on 6600mhz based cards does not OC particularly well.

I got the "worst RX 470" and ended up having better memory than many of the custom AIB partner cards. Memory speed is a big determining factor in Polaris 10's performance too.

Thanks, but I didn't buy this so I could overclock it, I know I'm an OLD geezer that appreciates using the latest gear but I will only leave it to you guys to push the envelope here because you lot signify the daring character of being TRUE hardcore overclockers.

This product shall live out it's life within an airy Silverstone Case doing nothing more special than some extremely light gaming and movie presentations. Just glad that AMD is still in business producing something decent for our money, despite our near worthless currency here in Convict Town.

More power to you then, enjoy your purchase. thumb.gif

KarathKasun the prices in retailers in UK/DE seems to have about 80 Euro difference between the 470 4Gb nitro and the 480 8 gb nitro that in my country seems to mean a +35% price if you want the 8Gb 480 one so i just went and placed an order for the 470 4gb nitro that is suposed to be at 1750 mhz speed for 235 eu

There was an 8 Gb 470 available for 273 eu but i decided thanks you you and the rest of the ppl around here that this should be the best price/performance ratio of all the polaris models AKA 470 4Gb nitro with 1750 mhz ram

your platinum also has 1750 mhz ram correct ?
