ATI Hd 7950/7970 bios mod thread - Page 127

post #1261 of 1288
in the 1st post in the thread there is a type it says
Quote:
. Ok 1070 core Hex is 01 C1 38, Ram is 1400 mem or in hex 02 22 E0,

01c138 would be 115,000 or for 1150 mhz, 1070 would be 0‭1 A1 F8‬. it threw me off when i was moding my bios to fix my 7950 boost that did not like idle voltage or ram clock changes.biggrin.gif

Try another 280 bios. Some of them won't work right for me either. I found an XFX one that works fine, but may or may not work for you https://www.techpowerup.com/vgabios/157308/xfx-r9280-3072-140302

If I change the Power limit range leaving minimum as default and max being 20% higher would cause any issue?
Exactly chaging the TDP would allow higher OC or it will draw more power even if it is at stock clock/underclocked?

the TDP sets the default power target, it will let it go up to the boost clock (bios or overdrive) and stay there so long as it does not thermal throttle or exceed power target. the % is what you can set in over drive. if you dont set anything in overdrive it will use the bios defaults.

it will also not use extra power just to do it, so higher TDP is higher default power target, higher % gives you a higher power option in over drive but is based on the tdp.

but I mean the manual power limit adjustment, If i leave it at default minimum power limit and only increase max power limit it can cause any problem , if I leave it at default clocks but lower vddc?

the % only changes wattage when overclocking in overdrive, you could set it to 100% in bios with no negative if you really wanted to since it will not change voltage or use extra power. aisc and VID change voltage not the power settings.

Okay so ive been out of the high end PC space for a bit and havent ventured this forum in a while. Anyone mind giving me a TDLR of modding BIOS and what or what it helps? Ive read the first post and a few other threads but dont seem to understand the difference/benefit between it and straight up overclocking.

Can someone help with xfx 280x bios.
Id is Tahiti B0 CR XT C38601, part nr 113-797atdfv33 with Elpida memory
The problem is there are 3 supported memory types and I'm not sure which is which...
xfx280x_default.zip 40k .zip file
I simply want to set tighter memory timings at default 950/1375 freq

Hey mate, if you go to this link

https://drive.google.com/open?id=0B2XVfIhkHZlfRDNXVTRXTGpiOU0

This bios should be the right one for you, it matches your card and is elpida optimised. If for some reason it's not right then go here...

https://drive.google.com/drive/folders/0B2XVfIhkHZlfQkNDR1hlZVdDeVE

Then scroll down to the xfx section you should find 5 or 6 bioses that match your card. I don't know if they are just multiple copies of each other but these should all be pretty close to optimal for you.
You might have to experiment a bit with a few or just compare in a hex editor.

Hope it works for you.
