Hi,
Do you only change DRAMTiming12 value to 7020?
Please share you OC settings.
Thx.
I am a little new. What is HXD? are you referring to HiveOs flash?
Where do you have the menu option to do all of the modifying?
thanks
Hey, nice work. Wondering if you may have any tips getting Vegas (I have 2x64 running 56 bios) to play nice with the rx5700 dd. Picked one up a couple days ago, and it will work fine by itself (without Vegas) in win or hive, on or off riser.
Not being detected as soon as Vegas are in the system. Tried it all, swapping slots on both card types, risers, turning off OC’s etc, to no avail. Once all connected only Vegas (even only a single one) will show up.
Btw, what are your straps for the Vegas? I’m getting 52.33 on both, yours are v nice!
I have Pulse 5700xt with one vega 56 that didnt fit into my vega rig, no issues, working nice together.
Vega is tuned down a bit to keep mem cool in these high ambient temps now …and allso i dont like vega´s high W readings next to 5700xt )
So has someone finally solve this?
If we copy and paste straps from 1500/1550 to all the others straps after it, do we need to set tREF to 6045 on all modified straps or do we need to change tREF according to this data?
I had the timing straps changed but I had not changed the tREF. So far it seems to have fixed my GPU Detected Dead error
Hi, I have same card (Red Devil RX5700X, Micron memory) How you moded the bios please share the instructions.
u need more power tool (MPT) and red bios editor (RBE).
First load your org bios to MPT and change on “power and voltage” tab minimun&maximum voltage GFX&SoC to 700 (690), some like to change Overdrive limits but not mandatory. U can allso set your “Power limit GPU W” to like 200…170 to your liking, not mandatory…its for protection if your oc´s fail´s the GPU wont ramp up to 220W cause some issue when mining…and overload your PSU.
Next hit save and name your MPT file so u can identify it…like “red_devil_700mV” or what ever.
Then Load same bios file (rom, not MPT) to Red bios editor (RBE), on “Power play” tab hit “Load MPT file” and locate your “red_devil_700mV” or what ever u named it, hit open, you get the message “Successfully loaded”, hit “OK”.
Go to VRAM Timings tab, first do the memory type that is open “K4Z80325BC”, select all and copy timings on “1500MHz” then paste that same string of numbers to all higher MHz timings, last “2250MHz”.
Save file, name and location to your preference, you can keep RBE open and LOAD the file u just saved and do the same to other memory type “MT61K256M32”, from “1500MHz” up to “2000MHz”…copy 1500 string to all above MHz timings (actually located below 1500 in app) , save bios file and flash to your GPU.
!
If u want to change tREF to x2 or x3 from the oem value, do that before changing the first memory type, like if tREF2850 to x2 =5700, then change the first tREF on mem (1500MHz) and so on as mentioned before.
After you have changed all and saved your .rom open the final .rom again in RBE and verify that all values are correct, tREF values and all timings above (below in app) 1500MHz on both mem type are the same.
I belive if u know your mem, you only need to do that type, if you are not sure, do both…no harm.
Then flash your GPU.
…just woke up…there might be some other stuff that i missed…so please feel free to correct my mistakes or add something i missed.
Please do your own research before bricking your GPU…this post is just for reference so be sure u know what u are doing.Cheers

Hi,
Thank you very much for the detailed valuable information. Initially before asking here in the forum I did only the VRAM Timings modification and flashed the bios. I did exactly as you described (watched red panda as well). Did not used MPT and tREF modification. The card worked as normal and hashing but MEM temperature is too high above 88 - 90 even at higher fan speeds. So I am unable to get HR above 50-53 because I have to lower the MEM clock and Voltage to lower the temps. I replaced the thermal pads as well, it was really in bad condition and oily. But still the MEM temperature is high.
But now I tried to flash original bios (downloaded from the card itself) to see if there is any reduction in MEM temperature, but while flashing with amdvbflash it shows, ROM not erased. Error 0FL01. Please help me to resolve this issue. Otherwise I cannot flash the complete mod as per your instruction which I desperately want to do it. I did -unlockrom and force commands but still unable to re-flash.
By the way I flashed only the OC bios. Silent bios intact untouched for safety.
Change pads

what u mean with red devil oc can be flashed once? i have also the red devil and flashed the oc mode.
The OC mode can be flashed only one time. Re-Flash is not possible even with the stock ROM. But the Silent mode can be flashed multiple time.
oh dayum. why is that? from where do you have this information? have x2 red devil’s. already flashed the oc-bios on both.
I mean you can flash OC bios once. But if you want to re-flash with stock rom or modified rom it won’t allow.
thats sad…
Hello, I personally use this value !!! on Ref
