Topic: AMD Rebrand - RX570 / RX580 - Official Thread - page 46. (Read 173441 times)

Does the SAPPHIRE Pulse RX 580 8GB have Samsung memory?

Currently I have 470's and 480's running, all 4gb versions of the cards, and MOST of my 470's are more efficient in a hash/watt ratio than my 480's, I do have a couple 470's that just pull massive amounts of power for seemingly no reason. I was assuming the same would be said with that 470-570 since it's just a rebrand.

Also you're saying you have 5 series cards working fine with a modded bios on the latest drivers?

I have had no problem with bios checks. I've vbios modded over 20 cards and run the latest drivers without issue. I do however disagree with your 570 assumption, but in the post just above I asked for tested numbers. 480 power efficiency and slightly higher hash more than paid for the extra cost versus the cheaper 470's.

Do the 5 series card's drivers have the Bios check on them? And if so, do they freak out if all you do is a simple strap mod on the bios? Trying to buy some more cards, and 570's seem like the best bet at this point, but trying to go around the bios check is going to be a pain.

A few GPU tests Sapphire 5xx. A few successes, but one problem.

I use:

Asus Z270F Strix - Without any problems, 7 GPUs work or MSI Z270-A Pro 6 GPU ready, I have tried, I currently operate about 10 Rigs without problem (RX 4xx)

Hynix on 570 is better then Hynix on 580. Hynix on 570 timing 7777 @ 1750 but 580 hynix 999 @ 1750 but i have to check this because the problem is two different time sets 1: 1750 and 2: 1750 each for another set of memories.


This is my tests, But I have a little problem. The signature for the modified bios driver is ok. But it does not work at the same time 570 with 580 on one motherboard.

If the 4x 570 works and re-sign the driver, the 580 runs but does not run 570.

Simply, it works either it or it. It does not work together.

Does anyone have any advice or idea?

Maybe a new Atipatcher?

Yeah, I guess I should have stated it.  So it is a 4Gb. 
And this test rig of mine is powered by a shitty Corsair 750W bronse PSU, so the power figures would be slightly better with a gold PSU.  Mobo draws ~40W idle.
