I guess this is an overclocking problem rather than a Bios problem ?
But remember that if your original Bios have settings for Micron AND Samsung memory, you have to save it twice to have the settings OK.
Also while I don’t have Samsung Memory (fortunately), it’s state that it won’t go up than 910Mhz.
Hi, i don´t understand this. In my rig i set 700mV Vcore - 750mV VDDCI - 1250 MVVD and is very stable and cool, but can I damage my card??? Thanks
I’m also unsure about this sentence…
If you want to be sure, go to igorlab forum and ask there.
Is the More Power Tool part neccessary to get i tworking?
I just adjusted timings on my original BIOS, and it bricked the card - would MPT fix the issue?
I have an ASRock 5600XT
Got same problem with ASrock 5600XT, after flashing modified bios, i cant see memory type in cards page in hive os… after flashing stock bios back i can see Micron memory again…
Found solution with bios from here - Unlock Modified BIOS for AMD Radeon RX 5600 XT samsung + micron + hynix (bitby.ru) 
Hey, thanks for pulling this all out and making it one nice easy to follow guide from that forum. This is great!
One question for the OP: did you do these same steps to the sapphire 5700xt cards as well? I was doing this for the gigabyte cards but hadn’t done it for sapphire. Also, which model sapphire, pulse or nitro? I have the pulse and I haven’t done much to them yet. But between one of the gigabyte and one of the pulse sapphire cards I’m getting reboots every 30-90 minutes.
I’m also having a similar issue with a power color of the 5700xt line.
Are these methods safe to use on all 5700xt? I did just the timing part and immediately saw an increase of a few MH/s with slightly lower power draw.
But even with not applying any overclocks to any one of the three specific cards I am having trouble with, I continue to get this instability. So frustrating. Lol gotta figure it out better
Thank you, will this work on Aorus 5700XT Rev. 2.0, Single Samsung Memory
Thanks, going to try this with the morepowertool seems like I get some random 0mhs which crashes. Hopefully this does the trick thanks for the great writeup!
Did you end up getting stability? Trying to get the same done on my strix cards
Hi,
I have an Asus dual 5700 non XT.
I downloaded the XT version, modded it by changing timing straps, and flashed it.
After OC I can’t send the card over 55MH, how can I boost it? Any suggestion?
Here you are the modded ROM and the OC settings.
Any help is much appreciated
Unfortunately I am actually finding more stability with phoenix over teamredminer. Not sure what it is I just can’t seem to get decent clock speeds out of teamred.
Did you get it working? Trying for my Sapphire lol
Ended up going back to TRM. Still trying to fine tune stability but basically get 57mhs at 102w
May I ask how you did that? I am curious what OC settings you used, and what you followed from this guide (did you use the MorePowerTool? Also which timings did you use for your card)? I have Samsung memory and would like to get around 55MH which I think is the max, but not really sure how. Feel free to send me a message as well if you’d like!
I got some help from the redpandamining discord and they helped with my bios. I just asked and looked around for some similar cards and clock settings in hive and have tweaked and gone from there.
Damn, those are nice results. I can’t seem to get 950 on my strix rx5700 flashed to strix xt. For the time being I have gone back to something that seems to work for me and also phoenix. I just seem to keep getting some crashing on TRM.
Thanks mate
I was not able to reach 900 till moding the tREF table, it made the biggest difference…
The MEM Mhz mod on it’s own wasn’t a big difference
what setting did you use to mod your BIOS?
Oh and I used Gminer
I used igorslab red bios tool but as mentioned before had some help from the people from RedPandaMining discord who took a look at my bios and changed a few settings.
