post #821 of 3471
I can probably find the ROM for your card on web, but would prefer to mod the one which is on your card, are you able to provide it?

Timescale may not be super fast on me setting up ROM, but will be done ASAP smile.gif .

I will probably be able to load it from the GPU, I have a regular PC that I can use to make sure nothing weird happens in the flashing progress. I will to my best to get the BIOS tomorrow (as I won't be home for the night). It's been years since I have flashed GPU's so I will need to read up on how to do it. Shouldn't be a problem though.

Thanks for being so kind and helpful!

No worries smile.gif , provide ROM, then I mod and give you instructions on flashing, etc wink.gif .

Forget reading anything, you will get the "package deal" FOC biggrin.gif .

I'm intrigued to aid you in this situation/platform wink.gif and look forward to results share smile.gif , it's something "new" vs the usual modding I've been partaking in wink.gif .

Speaking of that, can bios be edited so as default it goes to wanted clocks (and voltages, timings ) so rig can restart "headless" ? Can you do that?
post #825 of 3471
You can do that via Polaris Bios editor smile.gif .

Hello guys, I just installed this program for to undervolt (at the moment biggrin.gif) my Red Devil rx 480. I have a 85,5% asic, silence bios (max 1279 mhz). These are my Wattman modified settings, but I would like to decrease also state 0 (300 mhz) and adjusting state 1 and 2 (I am not able to set less than 800mv). So with Polaris bios editor if I set a lower voltage at 300 mhz will I also have lower voltages to the other states? And if yes, which one is the proportion? Otherwise is it possible to apply a static voltage at every state? Thank you! thumb.gif

Hello guys,

I've skimmed through this thread and haven't found much info about the newer non-reference 4GB RX480 card memory OC capabilities.

It seems everyone is talking about the 470s, but I have a feeling the 4GB 480 can still be the better card if done right, but apparently they are not done right.

reviews are stating that the 4GB version of the Sapphire Nitro+ RX480 carries weaker memory chips compared to the 8GB model and can only be OC'ed to about 7600Mhz.

here is the link by the way, read the paragraph under gpu-z screens.
http://www.legitreviews.com/sapphire-nitro-radeon-rx-480-4gb-video-card-review_184553/10

Same is shared here
http://www.kitguru.net/components/graphic-cards/zardon/sapphire-rx-480-nitro-oc-4gb-8gb-review/31/

Can someone confirm this? And what about the other 4GB 480 cards from MSI? Are they all sporting lower spec memory chips? Or does a bios mod fix the issue perhaps? Please share your experience.

Also please advise if there is any sense buying the 8GB RX 470 by Sapphire for $229 usd (memory clocked at 8000 by default) or if the 4GB Sapphire is still a better choice for $209 USD Memory clocked at 7000? I believe the 8gb version may carry better memory chips. Please advise. Memory speed is of priority here.

You can apply static voltages to the states because I have done it myself. There could be stability issues if you don't give 300MHz the required about of voltage, but give it a try and reply back.

The reason that nobody really talks about them is theyre kinda in pointless limbo. They use 7000mhz hynix/elpida which usually doesn't overclock well. The 4gb 480 is only slightly cheaper and is slower than the 8gb 480. It's slightly more expensive than the 4gb 470 and so close in performance purse practically the same as the 470 you may as well save and get the 470. The 300ish shaders don't provide enough of a boost in the 4gb configuration to matter and make it pull ahead of the 470 which already isn't far behind the 8gb 480.

Thanks for the resoponse, and what about the Nitro 470s memory chips on the 4GB vs 8GB version?
