Hawaii Bios Editing ( 290 / 290X / 295X2 / 390 / 390X ) - Page 203

post #2021 of 3796
Hi everyone,
I am new to the forum so if i misbehave please let me know ^^

I am trying to mod my 295x2 into a "395x2" if it had existed.
I downloaded the memory info tool to know which memory was installed and it displayed "H5GC2H24BFR"
I did that without having the drivers installed... i wasn't sure if it was the good way so i installed them and now the program doesn't display anything :/

Can anyone help me with that?
Thank you !

You have Hynix H5GC2H24BFR IMO, I don't know why after driver install it went blank, zip your ROM and attach to post will also double check what RAM IC supported in ROM smile.gif .

Seems you're right, as I have the reference design PCB i think i found my answer here
https://www.techpowerup.com/vgabios/157434/sapphire-r9295x2-4096-140311.html
http://ru.gecid.com/tags.php?s=radeon+r9+295x2

Ah damn i should have written it down when i installed the waterblocks biggrin.gif
Ill try to mod now and post the results if it works =)
post #2024 of 3796
I started modifying the master 295x2 rom i have and turns out i don't know what to do anymore
in the guide there is a step where it's needed to add padding to the modified ROM because the UEFI offset changes... well this rom doesn't have uefi.
I really don't know what to do so if anyone knows that would be great!
Thanks !

Hi gupsterg, and thank you for giving me first hynix 1.8 moded bios, he worked great but i have somes strange thing with, i have to put my core voltage at +200mv for got 1.221mv VDDC in full load, when my gpu is not highly used i have 1.331mv u_U only when with low loading, in iddle and full load he have low voltage, so low in full load uhu, i recently trying to use your last modded bios for me Final_MLU_390MC_75_803.zip 198k .zip file cause i was tired of high temp on my vrm (approximately 75 and somes fan noise), and your bios work and have so fcking good performance like your 1.8 modded bios but with lowest vrm temp, i think your bios work fine but have 1 problem, he's not really instable, he's just not giving the enough power, he's bugued at 120W, i tryed to put 300W with hawaiibiosreader but i have the same problem it change nothing frown.gif

Before 208W 208W 200A
Now 238W 238W 229A

What it is now works on my Vapor-X 290X for clocks of 1150/1575 @ 1.325V VID with no clock drops, I never run furmark but in things like 3DM FS / Heaven / Valley / Games / Folding@home all is good.

Hi, Thanks ! So i need to do the 390X timing mod only on UEFI capable bioses ? Or can i just ignore the UEFI offset part of the guide?
post #2029 of 3796
Thread Starter 
390 MC mod can be done on UEFI or non UEFI ROM.

Quickest easiest method for your case:-

i) skip the step of adjusting UEFI.

ii) do all other steps (except checksum using HD7xxx Series UEFI Patch Tool BETA)

iii) use hawaiireader to fix checksum

Check ROM is equal to or slightly less than 128kb once you finish mod, if so flash.

I will update OP better for non uefi roms smile.gif .

Thanks for being so fast again!

Here is what i did and it seems to be wrong as my RVE is stuck with code b2 "Legacy option rom initialization".

I modded both master and slave roms from sapphire that way.
-used the tables to find the vram info block and deleted it.
- paste inserted the 390X vram info
-added padding right at the end of it
- fixed checksum

As you can see i ignored the command table parts as on the guide it is mentioned this is not necessary... maybe that's my issue?
I actually dont understand what it is for tongue.gif

Also, for my previous mod (throttling temp) hawaii reader didn't work. the checksum fix actually modified a lot of bytes and corrupted the roms.
HD7xxx Series UEFI Patch Tool BETA however, worked.
