RBE 1.13 is out and allows checksum correct flash.

[jimmyz]

OK as the title says BAGZZlash over at Tech Power up has released RBE 1.13 this version allows many nice new features such as allowing the overdrive limit to be raised as high as you want and still use CCC, as well as the built in profile editor. the profile editor allows setting hidden features of the CCC such as fan speed and such. It is truly a usefull tool.

Please read the info provided thouroughly. including the "HELP ON THIS" part.

Any questions you should encounter are covered in the Bios editor's info. please read and understand before attempting flash, and keep a "virgin" file to flash back with if needed also you should make sure you have a spare PCI card to use in case you need to correct a bad flash.

now let's take a look.

Main page.
you can simply drag a bios file here to load or use the load feature and browse to it.

profile editor page.

To use the profile editor, use Catalyst to save a profile and name it so you can find it. By default the "load profile tool will go to the right folder, click on profiles folder and select the one you created.you should get this :

from this screen you can adjust and save your profiles so you can have fan settings and clockspeed increases just a hotkey away.


unlocking the limits of overdrive

This is the best part IMO. it allows you to use CCC overdrive to set clocks, and as we know Overdrive set's crossfire clocks far better and more reliably than AMD GPU TOOL can.

on this page you see two methods to change the limits. I recommend Method 1 but it has limited pre-canned format in method 2 you can set your own clocks but without a digital signature, some cards will not be seen by the drivers if this happens.

And the results!

If you find this program as usefull as I do please check out the "donations" tab in the about section of the tool. I know the author would appreciate it very much, after all he doesn't even have a 4xxx series he does all of this work for us simply out of kindness.

Jimmy, can you tell me what exactly has to be changed in the bios in order to get higher vcore on the graphics card ? Thanks

All you need is a 100k ohm pot and a steady hand

[HousERaT]

When using method 1 for unlocking overdrive, if you submit an entry to futuremark does the card show up as 4850 or 4870? Also what drivers does it work on so far?

it is a 4850 still , see in the gpu-z shots it says 9442 , 9440 would be a 4870. it works just like a stock 4850 bios but the drivers usually have to be for a 4870, just a quirk of the signature. and so far i only tested on 8.7 but it should work with any "official Drivers".

also to the overcrash. the only real way to mod voltage is a hard mod as the voltage reg. chip is basically only made to go so high.!.20 is maxx acording to W1zzard IIRC. luckily there are very easy mods for these cards.

[Rick Flair]

On a 4870,

Well lowering 2D voltage works, just lowered it to 1.153 and tested with multimeter.

Going to lower it more now .

And try raising 3D later.

Edit: lowered 2D to 1.103, measured with MM, works.

Edit 2: Seems like 1.103 is lowest BIOS editing will allow, with my hard voltmod this equals 1.16 in 2D for me.
If someone without a volt modded card could test the 2D lower limit and post back, but it seems 1.103 is lowest BIOS will allow.

Raising 3D voltage seems to do nothing, going to test some more.

Maybe someone with with a 4870 can try lowering 2D clocks and see if Overdrive still works, but I settle on regular clocks and 2D 1.103v and 3D 1.263v.

Edit 3: It seems that memory voltage is lowered both in 2D and 3D when enabling 2D core voltage lower power modes, 1000mhz memory was coming up with errors, back to ASUS TOP BIOS which is good for 1100mhz memory for me, but the lower 2D voltages was nice, hopefully it gets all fixed up.

[Dirton]

Rick Flair
Maybe you know the step of VRM change?
Is it just like AMD Overdrive utility tels here?


I tried changing 2D voltage till 1.103V, but it's somehow gets overwritten with the default 1.263V according to millimeter.
Well it seems, the new versions can't modify Diamond BIOS voltages, and it fails to move CCC limits my original Club3D (the same subsys like Diam. XOS) BIOS either (but voltages are fine :/). It shows that the mod till 990/1200 is possible, but after flashing BIOS and activating CCC the limits are all the same. Such a shame. Why can't it be both?

[Rick Flair]

Under additional features, 'One Click Update 4xx0'.

[Dirton]

Yeah, I did that on both BIOS'es several times, but only Club3D one was voltage modded successfully.

[Devious]

Nice update!

Thanks

[philbrown23]

i did not try the additional features tab yet, but that flashing works better than the previous versions

[Dirton]

Rick Flair
What CCC clock limits do you hane in your BIOS? Could you post it here if they are more then 790/1100?

[Toysoldier]

Using the "additional features tab" and the "one click update 4xx0 BIOS" with a tick in "also decrease voltages", lowered my idle temps to about 68 deg C.The fan now runs with 1000 to 1125 rpm in idle ( 23% )



Simply awesome :-) thanks a lot !!

[Rick Flair]

Can someone test something, it would seem the new features of RBE conflict with newer Catalyst drivers (8.52 and up) and I think it has to do with Powerplay being implemented in these drivers. Long story short, card will boot but drivers will say something is wrong with hardware, BIOS conflict with driver for sure.

With official 8.7 and lower drivers all newer features of RBE work fine.

Guess ATI is implementing more checks in newer drivers.

[Toysoldier]

Uninstalled Cat 8.7 booted into safe mode used driver sweeper and installed Cat 8.8 Beta with driver 8.52 and got the following.



I then flashed the card with the ASUS TOP Bios and rebooted and everything went fine.

I then went into RBE 1.13 and did the same as above except for the tick in "also decrease voltages" flashed the card again and it now works fine.
But to be sure I will uninstall the drivers again and then reinstall and see what happens. I really like the 68 deg C idle temp together with the low noise profile.

EDIT

Uninstalled CAT 8.8 beta booted into safe + used driver sweeper and installed again and now it works fine.
So it looks like RBE 1.13's also decrease voltages feature is doing something CAT 8.8 Beta doesn't like.

[BAGZZlash]

So it looks like RBE 1.13's also decrease voltages feature is doing something CAT 8.8 Beta doesn't like.

Interesting. So as soon as Catalyst 8.8 final is released, we should check if it likes the voltage decrease again. If not, I'll implement some kind of warning message or something.

I've checked with four different Catalyst versions from 8.52 to 8.54, its happens in all of them, I also tested then with 8.52 that was on Asus site before they got pulled yesterday.

But like I said earlier anything earlier driver 8.51.x (8.7 official) work fine.

Looks like next official Catalyst will be implementing PowerPlay and causing this nice little feature of RBE to not work.

[Dirton]

BAGZZlash, could you please look for some kind of over current protection parameter in 4870s BIOS? I've run some test and it strongly looks like there is some wall doesn't letting to overclock it. Here're the results I got:

Decreasing performance on extreme overclocking is normal. You'll see that even with CPUs.

[awdrifter]

I tried using method 1 and selected "change to these values", then I flashed the bios with it. But my OC limit in CCC is still 700, does anyone know what I'm doing wrong?

[fellix_bg]

It also doesn't seem to do anything for me, about the CCC clocks limit, even after reinstalling the driver.

[Dirton]

No, what I whanted to say is that GPU and MEM OC kills each other, the strugle for current. The more voltage I add, the more it becomes clear.

Got a bug in v1.13, sorry. This will work in v1.14, which will be released soon.

No problem I will wait for the next release, thanks for all the hardwork.

[Lightman]

Today I was playing with my 4870 512MB card trying to lower power consumption for media tasks, internet browsing and few things surprised me!

1. Lowering 2D GPU clock below 500MHz doesn't give much saving!
2. Lowering memory clock gives huge savings!!

My measurements (read from KillAWatt after 30 minutes browsing internet thus system warmed up ):
500GPU - 1025MEM = 251-255Watt
500GPU - 465MEM = 217-221Watt
170GPU - 465MEM = 216-220Watt

Looks like PowerPlay Clock Gating is working really well! On the other hand I can't see any power savings enabled or implemented for memory system.

BTW readouts were done on my system form sig underclocked to 1.6GHzCPU/2.2GHzNB on all cores and 1.1VCPU/1.25VNB.
Card flashed with ASUS TOP BIOS and tested under Vista X64 using BETA Cat. 8.8!

My conclusion is that we don't need to edit 2D GPU clocks in BIOS for power savings, we need to edit Memory clocks!
Now, anyone seen BIOS which doesn't have that annoying flickering when flashed with different 2D/3D memory clocks??
