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.

http://img204.imageshack.us/img204/7162/profileeditorzh6.jpg (http://imageshack.us)


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.

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 :D

[[XC] gomeler]

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?

[jimmyz]

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?
http://www.bestsergey.narod.ru/maxfrq.png

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% )

http://i132.photobucket.com/albums/q25/Webhiker/RBE113.png

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.

http://i132.photobucket.com/albums/q25/Webhiker/error.png

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. :down:

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?

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

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.

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!! :shocked:

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??

[drizzt5]

Is the lowest you get any power savings 500? Or does it not matter at all how low you make it :/ ? Nice findings though.

[Lightman]

500 is default for 2D on almost every HD4870, but you can set any reasonable value you want. MSI had BIOS with 2D set at 170MHz, but after my experiments I can't see a point in lowering GPU clock below default 2D.

Next I will try with lowering GPU voltages for 2D mode using RBE. That will unfortunately need to wait till Sunday :(.

Ahh man I tested almost the same as you when I saw the 4870X2 having a power consumption comparable to the 4870. Lowering mem speed to 200Mhz (lowest stable) lowered 30-35W friggin watts. Problem? Each time mem speed changes the image flickers, so changing it to lower values at idle is not an option. It's inherent to GDDR5 chips, so it can't be fixed by a BIOS update.

You would ask why?
Why both 4870X2 and 4850 have the 'complete' PowerPlay (it lowers core/mem speed and core voltage) and the 4870 not (only core speed/voltage, and voltage only with newer BIOS)? Why didn't they implement mem speed change too in the 4870 to lower its horrible power consumption at idle? The flicker would only occur when a 3D app is launched, so why? Ahh questions questions. My bet is the following:

Reading early 4850/70 reviews you noticed they said both cards have a feature that detects core load and changes between 2D/3D speed acordingly right? Try lowering your 2D mem clocks in BIOS. You'll notice that the card is constantly changing between 2D/3D clocks when an application or video is loaded or closed, i.e. ATITool or simply watching a video, and flickering like hell. That happens because that system is very sensitive and kicks in when it detects a load peak, even if it's very short in time, and we know that flicker is unnaceptable. So ATI was forced to left the GDDR5 mem present on the 4870 fixed at 3D speeds to prevent that.
But what about the 4870X2? It has proper 2D/3D mem clocks. Then what happened there? The answer is easy: in some reviews (TPU for example) you can read ATI disabled that system, and now the card is at 3D speeds only when a 3D intensive application is running in full screen. By disabling the 4850/70 system and implementing this new one ATI has been able to reduce flickering to only when firing up and closing a game because it completely ignores the load peaks caused by some actions at idle, which is acceptable. So the mem speed can now be changed and power consumption lowered.

I think ATI shooted themselves in the foot with that GPU load sensor, and I bet we won't see it in the next generation of cards. And if we end seeing it, power consumption of GDDR5 will remain sky high.

:2cents:

[awdrifter]

Just noticed you have a 4870, IIRC because it's using GDDR5, the bios is bigger, so you'll need to do something else. Sorry, I don't know the details. Hopefully someone else can help you.

Adding on to LuxZg 's quesions is that a 4870 or 4850 Dirton?

[Barr3l Rid3r]

It works fine, but I've seen a problem here, I can have upper limits in overdrive if I don't touch the voltage settings, but it doesn't work if I set 1.20V in VGPU (yes it gives me an 0,1V increase)

[mr2sw21]

so has any one tried on 4870? how to get the bios?

[LuxZg]

Adding on to LuxZg 's quesions is that a 4870 or 4850 Dirton?

I think it's 4870, as I don't think that 4850's have VRM temperatures/amperage shown in GPU-Z. At least one screenshot I've seen didn't have it..
EDIT: Stumbeled on him in other thread - Dirton:"Hi, at last I've voltmoded my 4870."

So it's 4870, unless he has several cards :D

EDIT: If you jump to TPU thread you'll notice similar results starting to get posted. With new ATi Tray Tools beta v1.5.8.1250, and a BIOS that has lower voltages enabled (either "-105" version that's floating around, or one tweaked with RBE 1.13), you can change all options on the fly without using multiple tools. I still don't have low-volt bios on my card, but have made two ATT profiles with different clocks & fan profiles, and works like a charm. Others have confirmed that with low-volt tweak in BIOS, you can create one profile for 2D (let's say 160core/250mem/1,083V/25% fan) and another for 3D (800core/1100mem/1,263V/50% fan). I've actualy made mine with two different auto-fan settings ;)

But once more - you'll have to tweak your bios with RBE 1.13 (or 1.14 once it gets out) to solve lowering voltages, and "spin-up bug" since you won't be able to lower voltage with reference "-100" BIOS, and if you use automatic fan profiles you'll expirience spinups to 84% every now and than..

To me, seems like RBE+ATT will be a very good solution, both for low-2D consumprion, and high-3D overclocks, and very soon indeed :) I'll just wait for RBE 1.14 first ;)

4870 with stock cooling without vmod. It's really nothing special, low clocks + 1.103v in IDLE. The diamond BIOS seem to be less stable when I try lowering memory clocks, so I use original (club3d) BIOS instead.
Thanks to Ray Adams and he's ATT there is no need in having limits upped in CCC, ATT does the job just perfect.

ASUS TOP bios, and Diamond XOC. Both are on TechPowerUp BIOS repository, you'll notice them by higher clocks and different version.

They can be modified, but you can't "infuse" them with low-voltage patch, since they are not -100 version so that whole "one click" is greyed out.

I've written it somewhere, if you could make these two tweak options separate, one for "-100" to "-RBE" version, and other separate for "lower voltage".

If you need more info, just yell anywhere, I read pretty much all importat threads connected to 4870 and tools like RBE ;)

[BAGZZlash]

Thanks man, I appreciate that. :up:
The thing is that I had a -100 and a -105 BIOS to compare them. They are exactly the same, except for a few bytes that are relevant for powerplay and some other stuff I was able to figure out. I don't know more exactly what these bytes are used for. Everything RBE does is checking if the bytes at those positions are at certaint values and if, it can be sure it has a valid -100 BIOS. If even one bit of even one of the bytes differs, the option in RBE is greyed out for safety reasons. I got someone who was willing to test an ASUS Top-BIOS where the new values were written to the positions forcely, and it didn't make any noticable effect. As long as I don't know more about what those bytes do, RBE will run it "safety first", sorry... :rolleyes:

[LuxZg]

Ok, sounds logical, tnx for explanation :)
Ofcourse I'd rather have safety, than extra 10-20MHz overclock that ASUS allegedly gives.. For me it wasn't that much of a problem anyway, since RBE allows enough tweaks of the stock BIOS to be very satisfied ;)

Info for Bagzzlash! And others as well :)

LINK TO THE POST (http://www.xtremesystems.org/forums/showpost.php?p=3236290&postcount=37) with some new BIOS from ATi, with some interesting stuff in it. I'm at work so can't test it, but read the post text and it will sound interesting. Specialy if this is really from ATI and not from Diamond (guy did say ATI explicitly, so should be official).

It has unlocked CCC overdrive, and seems they did something to voltages as well. You'll get exe file that auto-flashes the card, but you can extract it (I've done it with PowerArchiver, but probably WinRAR will work too), and you'll get the files. "4870-128Kb512MBOC795-1100MHz.sb" can be opened in RBE no problem and shows this:
BIOS DATE: 08/13/08 13:01
VERSION: 113-BA0701-100
ATOMBIOS VERSION: ATOMBIOSBK-ATI VER011.003.000.001.029254
500/1100/1,276V 2D
795/1100/1,276V 3D

Note - higher voltage! As soon as I get home I'll flash it, try it, and see if it really ups the volts, and if you can use lower volts as well.

Also, 990/1250 is upper OC limit in CCC.

This should be official ATI driver for boards based on reference design, so start flashing ppl! :)

Btw, I have posted or will be posting this in other threads too, as it is VERY interesting info, and I guess as many people know about it and test it - the better ;)

Cya all!

EDIT: 4870 cards bios, ofcourse..

EDIT2: I'm home now, and can confirm that voltages are up a bit, roughly +0,02V under load with card running on 795/1100 (vs stock bios and 790/1100 OC). Lowering voltage does not work, and you can't do the "low volt tweak" with RBE 1.13 (you can, but it won't actually change voltage once you flash it). Also, you do get unlocked Overdrive which works with 8.8 Cat's

Beware of what you recommend! That new BIOS you're referring to is for 4870 XOC!! The user on the post above has a 4850!!!

Thanks, that's exctly what I need.. an original Bios for Qimonda 4850s that has unlocked overdrive and slight higher voltages. or a fixed RBE version, that works forever.

I hate to OC it manually every time Vista starts, and dislike to made crappy solutions, different then overclock using standard latest driver or modded bios that works..

RBE v1.14 (http://www.techpowerup.com/downloads/Utilities/RBE/) is available now!

Here are the new things:

v1.14
- Fixed bug with method one overdrive hack not working. Should run fine now.
- Added fan control for 4870 X2. Completely new controller chip, was a big pain in the ass to code... :-/
- Made spin up fix, powerplay functionality and voltage decrease in the one-click update for 4xx0 cards seperately selectable.
- Fixed WinFlash check sum correction bug.
- Added and fixed a lot of small things. Too many and too minor to mention all... :-)

Please tell me your opinion about everything! :)

Ooops, I mean HUGE OOPS! Sorry Barrel Rider, DO NOT flash with that bios as it's for 4870 and not 4850 cards ! I made a HUGE mistake there!

@bagzzlash - tnx for a new version, will try out right away :)

EDIT: Well, my overdrive is 990/1200 and I have Cat 8.8. I hope it will work fine for your 4850 as well! All other functions seem to work as well

But u used method 1 hash right?

Yes, first method, through that new dropdown menu.. OK, you need 900, and it's a bit lower than that in first method for 4850's :( But than you should try Ati tray tools (new beta, see on guru3d forum), it has auto-clocking which alows you to set any clocks speeds, and if you make 2 profiles (2d and 3d) you'll be fine even if RBE or BIOS isn't unlocked and tweaked.

Btw, if you know your max, why don't you just edit BIOS and leave 2d clocks as they are, and 3d clocks to the 900/2150 that you have..?

So, now it's working? There are dozens of clock settings, wich os those are for 3D Clocks?

[LuxZg]

When you click on text box of any clock/voltage you'll get info in the box on the bottom for what is that setting.. You'll notice :)

When you click it, the right description gets highlited below.

Also, all 2d clocks are usually defaulted to lower GPU (like 500MHz for 4870, not sure what is def. for 4850), so all colums with lower value on top are 2D, and should be the same. All the rest are for 3D. That's a rough division :D

RBE v1.15 (http://www.techpowerup.com/downloads/Utilities/RBE/) is ready for download!

That's the changes:

v1.15
- Fixed bug causing an error message on loading several BIOSes (small ones like several 3870 X2 BIOSes).
- Added remote control feature for WinFlash to acquire and flash BIOSes from within RBE. Will be included in the tutorial soon.
- Superior PowerPlay should be available for more 4870 BIOSes now.
- Added link to the tutorial in the menu bar. (Info... Tutorial on how to use RBE (websource)...)
- Added display for the card's internal voltage table (it's in the clock settings tab).
- Fixed a bug causing the device ID being written incorrectly if it's changed in rare cases. Coded this very drunk, there might be bugs... :-/
- Added some nice method one hack signatures (4850, 4870 X2).
- Added a feature for method one overdrive hack signature saving and loading.

Have fun using it and please be sure to make extensive use of the signatures exchanging thread (http://forums.techpowerup.com/showthread.php?t=70980)!

I tried to change Voltages on an Asus 4850 using RBE v1.15 with no luck, card works on 2d (DOS) but hangs when booting OS.

The card is non reference, has the Glaciator cooler and the 3 phase design used in some Asus 4850 Top cards, also CCC limit for GPU is 800 in the original BIOS.

Is this BIOS unmodable for VGPU?
