VBE7 - vBIOS Editor for Radeon HD 7000 series cards

I have an ASUS R9 270 DCU II but can't go over 1220 voltage ( locked) can I bios mod ? I tried every overclocking software but no veil. So can I bios mod it ? Or can any of you bios mode my original bios ? to increase voltage limit ?
 
Hello Sentye, can you edit the bios of my Asus R9 290, please?
I need the fan speed increased. :)

This bios 67B1HB.15.41.0.2.AS06L (113-AD63300-103) is old.
I have the new bios 67B1HB.15.41.0.2.AS08L (113-AD63300-104) and
the fan profile of your bios is too high.
Little bit lower would be perfect.

wow. I don't know about 104 version. Thanks I'll try
what profile do you suggest?

Current fan profile:

Temperature Hysteresis = 6°C
First temperature = 50°C
Second temperature = 90°C
Third temperature = 110°C
Fan speed (for first temp) = 20%
Fan speed (for second temp) = 55%
Fan speed (for third temp) = 80%
Fourth temperature (max temp) = 110°C


This setting would be good:

Temperature Hysteresis = 6°C
First temperature = 40°C
Second temperature = 80°C
Third temperature = 105°C
Fan speed (for first temp) = 20%
Fan speed (for second temp) = 60%
Fan speed (for third temp) = 90%
Fourth temperature (max temp) = 105°C

83° when running furmark under load, test time 30 min.
The card goes not higher than 85°.
The 94° i never see.

I folks, I have a Gigabyte R9 280x oc rev.2 (Bios F70)

How do I change the VDDC, using this tool? I can't raise the VDDC above 1200 in the drop down boxes on the 'PowerPlay' tab.
I was hoping to get to 1256 to see if it alleviates some artifacting in Shadow of Mordor.

EDIT1: VBE7.0.0.7b version must be glitched?

I just tried version 7.0.0.7a and previous versions and they're fine, including properly identifying the VRM.

EDIT2: I just tried setting VDDC to 1256, leaving default clocks 1100/1500. The card crashed while I was in the Shadow of Mordor menu.

Best way to create a fan curve is to observe your highest idle temperature. Then set the fan to minimum fan speed and go 5°C over this limit. In my HD7950 case at 30% fan speed (which is minimum and super silent), it stays at around 50-55°C in idle. After this i ramp up the RPM straight to 48% at 60°C already and keep the line straight all the way to 85°C. Reason for 48% is that it's the highest fan speed at which the acoustics are very good with WindForce3X cooler where at 50% (just 2% higher) it creates a really annoying fan noise that is pretty much unbearable. I found this by setting fan speed by hand 1% at a time and listen to the fan noise. I stopped at 48% because that was the highest for my cooler that still allows decent cooling capabilities.

After testing, this creates an incredibly more silent experience at cost of some of the cooling but still keeping the card within reasonable thermal levels at 83°C when playing Defense Grid 2 maxed and with 16xAF and 4xEQ applied additionally. I just have to perform further testing within a a case with low air circulation and low case fan speeds to see how it works long term in demanding games. So far it doesn't really go out of the straight line segment, meaning it doesn't really become any louder than what i found most pleasing to my ears anyway. And 48% is in my case the sweet spot.

It's just strange that engineers don't go this far and design card cooling with such care. They always play it safe and make the damn cards loud as hell just so they meet really low heat. I'm experiencing other issues (heat) because my card is so overclocked, but with stock clocks they could easly do it. But they haven't, not even for my WindForce3X card which has like a freakin massive cooler.
 
Can someone explain me why voltage doesn't get decreased when i have it overvolted but does with default BIOS?

With default BIOS, 3rd state has 1.090 V, but in Windows when it's idling, it's using 0.950 V. Which is what 2nd state has set in BIOS. But if i modify 3rd performance state to 1.218V which is what i need for 1175MHz core, it stays at 1.218 V entire time even when idling and doesn't ever go to 2nd state and use lower voltage despite core indeed running at 500MHz. Is this VBE bug or something else? I don't get it...

I was expecting my 1.218 V for 1175MHz, but when it's idling at 500MHz it should be at 0.950 V. But it doesn't do that. Why?
 
Hi! I was wondering if there there's a way to add predefined voltage on none supported vrms? I have 2 7850s and can't seem to find the lowest voltage it would ran at 1050. The predefined voltage that are listed were either too high or to low. I need a 1.075 and a 1.085 for both of my card. I'd really appreciate if you can help me out. Thank you.
 
Please help I can't make any changes to my bios without getting BSOD upon reboot.

I'm already using a custom bios (built with VBE) with my Gigabyte 7870 and just want to make changes to the fan profile.

The problem is I always get BSOD SYSTEM_SERVICE_EXCEPTION 0x0000003b when i reboot windows after flashing any changes.
If I start in safe mode and uninstall the AMD driver windows will boot properly but I then can't reinstall the driver because it always gives a BSOD: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED 0x1000007e during the install process.

The only way I can get everything working again is flashing the original custom BIOS. Even tried display driver uninstaller to completely wipe AMD from the system but still get the BSOD! argh

I've had 300W on my card and it was fine.
 
This utility is wonderful. Thank you.
I've managed to change GPU clock from stock 925 MHz to 1000 MHz, Memory from 1400 MHz to 1500 MHz, TDP and fan profile on Sapphire R7 265 Dual-X.
It gives small but noticeable boost in Metro: Last Light.

Please, is there any chance in future, for possibility to change voltage (undervolt) with VBE7 on IR356x? It is for MSI Radeon 280X version 1.2 (IR3563B).

This same problem happened to me with Sapphire DUAL-X R7 265. I finally solved it using following steps:

1) Original vBIOS (Unaltered) saved from GPU directly with GPU-Z vBIOS save feature must be used.

2) This is how I altered the voltages, clock and TDP from original values using VBE7.0.0.7b:

I set the TDP Limit to 0 and adjusted to max TDP limit for my card (see grayed out power limit values).

3) Saved and flashed vBIOS using ATIFLASH. Don't modify already modded vBIOS.

4) Restarted PC, opened CCC-->Performance-->AMD OverDrive, clicked defaults for that page and apply. CCC has a bug which may not allow to apply the defaults right away, if so happens then click enable graphics overdrive-->apply then click defaults-->apply.

5) Turn off PC completely. Start it after 5-10 Minutes. I have ASPM disabled in windows power options.

This not only solved the issue for me, but also enabled AMD ZeroCore which also was disabled after flashing vBIOS. This dropped wattage during normal desktop usage to under 3 watts! I have set monitor to turn off after 3 minutes of inactivity. When this happens, GPU completely powers down, fans stop spinning and wakes up whenever I move mouse or press any key. I've attached GPU-Z log below displaying this.

Well finally tracked down my BSOD problem. It was the fan profile I was trying to use. VBE allows you to have multiple fan points set to the same temperature but if you do this you will get BSOD's as above (at least with a 7870). Hopefully VBE author fix it so that fan point temp must be greater than previous point.
 
Hello Sentye, can you help me with editing of my PowerColor HD 7770 bios, please?
The problem is that in 2D the card all of a sudden started to flicker and cover whole screen with artifacts. No changes were done to OS/software/card.
Clocks are switching from default 1100/1125 to 300/150 like crazy while i'm in 2d. I'm using 2560*1440 display and can't do anything except games now)) in 3d everything is perfect as of now.
2D clocks editing is disabled, but i noticed that you've helped with the same issues several pages ago.
I need it to be switched to the same clocks as in 3D, or maybe 450/750 without voltage increase

Any help is much appreciated.

UPDATE:
I've solved this issue with this guide http://www.techpowerup.com/forums/threads/updated-amd-ati-2d-clock-guide.117633/
using additional Catalyst profile with high clocks & voltage.
