Some help please.

I just used a mod for my rx470 8gb....Everything installed correctly.

Restarted pc and its fine, as few seconds in as soon as I open a folder or do something the whole screen turns blue. (plain blue, no writing)

Any help would be much appreciated.

3rd restart and the card seems fine now.....Could it be ram?

Thank you
I had this happen when using someones modded bios.  Had modded straps, and also mem set to 2250Mhz.  I would get artifacts all over, then whole blue screen like yours right after desktop.  I set to 2000Mhz and kept straps, still bout 4-5H/s boost.  You can experiment with mvddc, and mem clocks.  Can do mem clocks with Wattman or watttool.  Don't overvolt memory too much though....

To flash bios back, use different card as display (easy to do with risers!). Also better to at the computer (not remote....).

Thanks for the help, feel better now. Thought I done something wrong and stuffed the card.

Blue screen is back again..

Your blue screen stop coming after lowering mhz to 2000? or did you up the MVDDC too?

I had to remove v1.0 and v1.1 from google drive and mega, because I was pointed that I used a small part of mrb's work.
It will take up to 24 hours to revise my code and create own implementation, then I will upload updated version.


Details are:

Oh, you are correct, I really missed this point. I was in a big hurry to release first version asap, so I concentrated on main Wagner's algo,
blake is not interesting for me at this point since it takes only 10% of total GPU time and it's trivial in fact, blake algo is not that I can call something new.
But to make some start point asap I included your blake.c into my sources and then forgot about it and did not create my implementation. That's what happens if you are in a hurry.
It is very unpleasant situation for me, I will do the following:

1. I remove v1.0 and v1.1 versions of my miner. In fact, I already removed current packages from google drive and MEGA, I will upload updated versions soon.
In next version I will remove your blake.c from my sources.
2. I apologize, it's only my fault that I used this part of your code. I was not going to do it in public version.
3. I want to send you some compensation from my ZEC dev fee if you don't mind, just send me your ZEC address.
4. I'm not going to hide my fault in any way, I will post this message in my miner thread in first post.

Thank you for doing the right thing. I fetched your new tarball Claymore's ZCash AMD GPU Miner v1.1 Beta - LINUX - Catalyst 15.12.tar.gz and can confirm you included the MIT license as mandated in your "Readme!!!.txt" file, as quoted below.

You are in no way obligated to "pay" me. But if you feel this can help re-establish some of your image and reputation, feel free to publicly send to my donation address t1cVviFvgJinQ4w3C2m2CfRxgP5DnHYaoFC

You are now fully compliant with the MIT license. I hope my SILENTARMY code was useful to you  Wink

I'm happy that we close this issue! I also donated 5 ZEC to your address t1cVviFvgJinQ4w3C2m2CfRxgP5DnHYaoFC

SUPER GREEDY selfish dev that stole & got caught with pants down but at least he admits it so i take my hat off to you, but you were using mrb's code & you used it for commercial gains & you made a MINIMUM of 30-50 BTC from the 2.5% FEES !

You just sent 5 ZEC to mrb ?

SUPER SHAMEFUL !

So quick to judge people ...
Why not just believe Claymore's version of the facts ?
Claymore has made its own version of the code now and this is faster, as he promised.
I give him the benefice of the doubt and believe this was not intentional.

2x MSI RX480 8GB, Getting 80-90H/s

https://i.imgur.com/qaCDTpB.png



You can push those each up to ~52 ish, I have the same card, you need ~3 modifications to the Bios.
use the Polaris bios editior to

Change memory strap: to 777000000000000022339D00CE516A3D9055111230CB4409004AE600740114206A8900A00200312 0150F292F94273116
then bump the memory speed to 2200
and change the mem voltage from 975 to like 1025-1050 (this is needed for stability i found at 975 it crashes every few hours)

massive your millage may very but all the cool kids are doing it so, gl!


I just flashed it,

Getting upto 53H/s per 480! Smiley

@Za1n is right, though. You can go either way to fix the problem, depending on your priority.

Enter Safe Mode, disable the video card in Device Manager, restart the PC, flash the BIOS back to stock, and reenable the video card. If you still want to use the modded BIOS, I would raise MVDDC with Polaris BIOS Editor.

What would you raise the MVDDC too?

Should I up it only slightly?

You can boot into the OS, so MVDDC should be pretty close to the sweet spot. I would give it +10mV or +20mV.

I see.

Most likely this was the prob, not ram right?

Thank you both for your help, really appreciate it.

Thank you

Yes, from what I recall a black freeze screen indicates core issues and a blue freeze screen indicates its the RAM being pushed too aggressively. Either back down the clocks a bit or up the voltage a smidgen.

Edit: Seen your update, even if it appears fine now if you haven't made any changes to rectify the original cause you may run into future issues. I would still back off slightly or adjust the voltage up a bit to head off future troubles.

Seems to be working now after a few restarts....

I did not edit myself, I was using a mod from the eth forum which has been working for other people...

I have 4gb ram, I can add another 4gb and see how it goes...

The watts are fluctuating a lot can jump up or down 20 - 30 watts at a time..

V2 is breaking all my rigs, rolling back to v1.  failing OCL, and other weirdness... All rigs affected are RX470 or RX480 rigs.

Update: Got it sorted out I think.  Had to use a bigger HAMMER... Running V2 and looks good so far.

How about Sapphire RX 480 4GB with 2.0 version?
45 or less?

51 here

Marvell1, thanks for your fast reply!
Going tomorrow to pickup some 480 4GB models, because everyone gives reply about 470 8GB models.
Thanks again.

I have 470s with 8GB and they are better than the 480s due to superior Samsung memory

4GB 480s are barelybetter than any other 470 4GB, the 470s 4GB with modded straps do 49 50 sols as well with V2
