RBE - General information and discussion

[VuurVOS]

Sorry mate. I found no succes stories with a HD4870 soft voltmod. At the moment only the HD4850 can use of a softmod

 

[passionne]

OK, thank you for your feedback.

 

[LifeOnMars]

hi guys, looking to flash my powercolor hd4850 but don't know where to start ( is there a guide anywhere?) I have already downloaded atiflash and RBE both the latest versions. So, any help for a total noob at this sort of thing.

Hi - does this program work on Gecube 3870 Turbo (oc) cards?

Hi - does this program work on Gecube 3870 Turbo (oc) cards?

Like this one for example? Of course.

 

[markino]

Hi Bagzzlash - thanks for the reply.

Is that bin file a bios? What does it do (change)?

I'm thinking about getting one of these cards (Gecube 3870 turbo), but I was hoping I could use your program to adjust the Powerplay 2d settings - at the moment these cards use a bit more power at idle than a reference 3870. Will it do that?

thanks again

 

[markino]

Does anyone know?

 

[tomcug]

Of course, it will do that. You can adjust clocks as you want with this tool.

Yes, the bin is a binary file of your bios. What does RBE change? It change values within the bios file.

If you can change those clocks/volt correctly otherwise if you lower it too much your card could cause your system unable to boot or will crash switchen between those clock states.

Few tips
1. Never edit the boot clocks. If you edit those wrong your system will unable to boot.
2. Lower the voltage in small steps. I suggest you dont edit the lower 3D and higher 3D states because the graphics card is more often in 2D mode than 3D mode (if you use mostly your pc for office/msn/download etc)
3. Make a backup of the orginal bios
4. Make a backup plan if the flash goes wrong (blind flash, pci graphics card etc)
5. Have a second pc which you can use for internet to search information if something goes wrong.

Thanks Vuurvos, all good tips.

tomcug - I know what the tool is designed to do - I have read through all 14 pages of this forum!

I was asking about THIS specific card (Gecube 3870 Turbo) - I believe that this card has a non-standard bios which is not compatible with other cards, and I wanted to know that this tool could work with it specifically.

If RBE can open the BIOS file, it can surely process it. RBE has a sophisticated BIOS analysis routine ensuring it to tinker only with settings safe to be tinkered with.
One exception, though: If the card uses a non-standard fan which isn't controlled by the card's internal fan controller, programming the controller correctly can't afflict the fan, of course.

 

[markino]

Thanks Bagzzlash - I've just found out that the card does not have thermal monitoring! I didn't think you could still buy cards that don't have thermal monitoring, especially overclocked cards.

Presumably this would mean I couldn't set the fan to different speeds depending on temperature - so I think I'll have to send the card back anyway.

 

[markino]

Okay, I have now ordered the proper thermally monitored card.

Bagzzlash - when you say 'a non-standard fan which isn't controlled by the card's internal fan controller', do you mean a fan that is connected to the motherboard etc? So any fan that is connected to the 3870 itself should be fine?

 

[VuurVOS]

Every fan with 2 wires has no fan control. Even as the bios support it. For fan control you need a fan with 4 wires (those fans have PWM support)

 

[markino]

It is a 4-wire fan which I believe is connected to the card itself.

 

[VuurVOS]

If you post the link/model of the card here, we could confirm it for you

 

[markino]

Thanks VuurVOS - it's the:

RADEON RV670XT , 512MB GDDR4, HDMI, Dual DVI (2 Dual link, HDCP) / TVO(HDTV), Dual Slot Fansink with Thermal monitoring, O/C Edition (X-Turbo III)

If you like my advice, don't buy a pre-OC-card that's equipped with a fan that's different than the reference design. Just buy a cheap reference-3870 like the one from Sapphire. Apply your overclocking via RBE and be happy then saving hard earned money.

 

[markino]

Well, I bought it mainly for the fan, which is supposed to be efficient and quiet. I didn't buy it for the overclocking, as I knew I'd be likely to overclock it later if I wanted to (which I probably wouldn't bother to do).

Anyway, it actually costs less than a lot of the other reference 3870 cards.

 

[markino]

By the way, Bagzzlash - from the point of view of your software, why is the fan on this card non-reference? It is still just a fan that is controlled by the card/bios, isn't it?

 

[VuurVOS]

Its hard to see how many wires the fan has.

Like BAGZZlash said buy another card. factory overclocked cards cost often too much for the extra preformance. If you realy want a silent card, buy the cheaper reference card and put an Arctic Twin Turbo or Arctic Accelero S1 Rev. 2 (Passive) on it.

 

[markino]

Thanks, but I've already bought this one. I don't really want the hassle of fitting a different cooler to it, especially when I've already bought this one specifically for the cooler.

And I did already say that I didn't buy this card for the overclocking, and that it wasn't more expensive than other 3870 cards - it was actually cheaper. And it's WAY cheaper than buying both a more expensive reference card AND a 3rd party cooler.

Anyway, if I did want to overclock, this card is guaranteed to overclock up to a certain amount - most reference cards are not. Although from what I have ready, overclocking these cards doesn't give much performance increase anyway.

I'm much more concerned with getting it to run cool and quiet, and using as little power as possible.

Again, as I already mentioned, it is a 4-wire fan, as you can see here:

Is there any work ongoing to also allow on the ATI based BIOS's to increase/decrease the core voltage, memory voltage and also to tweak the memory timings?

Questions about RBE

1. will it work on 3870 cards?
2. how do you load the bios that is already on the card?

1. will it work on 3870 cards?
2. how do you load the bios that is already on the card?

1, Yes
2, Download GPU-Z and use the bios dump button
