Fedback needed: Which HD 3xxx cards support software voltage control?

[W1zzard]

while researching voltage control on latest ATI cards I found out that a lot of cards do not have ANY software voltage control at all.

If you have a HD 3xxx or 2600 card, please check the configuration of resistor R636/R639.

If it is placed HORIZONTALLY your card can support (limited) voltage changes.
If it is placed VERTICALLY your card can not support any software voltage changes, get the soldering iron out.

For reference here are two pictures:

Please report back your card's manufacturer, model, PCB number (GPU side near the top edge of the PCB usually) in this thread

[KainXS]

I'll check mine in a while but I don't think it supports it off the top of my head

Edit
I just checked my 2 powercolor 3850 256mb cards and both are horizontal with the part number 109-B34031-00

http://img.techpowerup.org/080221/2127P1010374fddfs.jpg

so I guess it does support it

So do I just need to solder or pen a horizontal line then? What is the use of having them connected vertically, or are the resistors just placed differently?

I looked too! I couldn't find any chips similar to the ones soldered onto the PCB with multiple pins on each side, except maybe to the upper right of the GPUs, but the numbers are obviously different.

[largon]

HD3870X2 does not have this resistor as the phase controllers are totally different (uPI uP6201 vs. Volterra 1165MF).

Hi, could someone please post a picture of the graphics card as a whole with a circle around the bit we are looking at, I think I have found it, but just want to check the orientation and position, if I am looking in the right place from the right direction, there is a damn lot of circuitry ontop of these cards,

Thanks.

[Silverel]

while researching voltage control on latest ATI cards I found out that a lot of cards do not have ANY software voltage control at all.

That'd be the first post. R636/R639 is actually one resistor but two different positions it can be in. On my card it was on the end opposite the DVI ports. You'll be looking on the back. It's tricky to find, but just look for the large (relatively) black chip and try to spot those two numbers.

When looking at it, you want the PCI slot to be pointing down, and the DVI ports to be to your right. AFAIK

[KainXS]

I REALLY want software voltage control so

BUMP

somebody please post with info on your cards

HIS ICEQ3 3870 NON-Turbo - Seems to be horizontal

http://i50.photobucket.com/albums/f347/jamfitz86/PC/resistorthingy.jpg

I'm not sure what the PCB number is and I cant be bothered taking the card and cooler back out/off. Sorry. here's what I've got.
http://i50.photobucket.com/albums/f347/jamfitz86/PC/number.jpg

What does this have the potential to allow? Higher core speeds without the pencil mod?

JAmes.

[DanishDevil]

Should allow you to basically do the pencil mod (to a smaller extent most likely) through software, rather than physically on the card. That way, you could dial in a specific voltage rather than test and retest with graphite shavings :)

Is your card, the "non-turbo" the stock clocked HIS with the ICEQ3 cooler that they're selling on Newegg for about $200? (model number H387QS512NP)

http://www.newegg.com/Product/Product.aspx?Item=N82E16814161218

[jammy86]

Is that without VAT? even if it is its darn cheap!

yeah thats the card. I've got the turbo BIOS running on it with no probs. If anything the turbo bios is better as it has better fan control (if your not setting the fan yourself).

JAmes.

[DanishDevil]

Sweet! I JUST ordered it too. I'll post mine next week when I'm home with it!

[jammy86]

Good luck with it :)

I cant get past 10k marks. but I'm pretty sure i'm cpu and cheapo ram limited. runs everything sweet :)

this number is from atiflash dos : 113-ba3901-024
does it mean i cant even change volts with bios mod ?

[DanishDevil]

Most likely. I assume software and bios voltage control would both be doomed by a vertical configured card.

You can still pencilmod. Check out the thread in this forum on the top if you're willing to put some work and time into it.

[philbrown23]

I'm getting mine tomorrow then I'll post some up it's the Ice-q from newegg for 200 Now is there a program that supports software voltage control?? Also can someone pm me with how to flash the turbo bios onto the regular Ice-q???

Not sure where the PCB number is. But I see in a previous post, someone has already posted a Powercolor 3870 with same clocks, so it must be the same.

Edit2:
I have noticed the voltage on this Powercolor 3870, being changed when it goes into 3D. I have it pencil modded to 1.42v. When it goes into 3D it goes to 1.45v

I have tried some bios with different (lower 2D) voltages , but they do not change the volts, maybe it is using some other area of the bios? I wouldn't know where or how to check unfortunetly

[philbrown23]

well my HIS is great!! it does have the horizontal component. also I flashed the turbo bios and it went alot easier than I thought!! I got the new dfi x38 coming and another Ice-q and I will be flashing that one with the turbo bios also!

it is vertical, but that only means there's no software control for voltage. you can still volt mod your card.

2900's voltage control was easy to implement in software. 38x0 on the other hand, not so much. it's possible(hence this thread), just a PITA to implement.

I have to look at my cards tonight when I get home, and it might be difficult for me to look at the resistor. I cannot take out the cards, I would have to disassemble my entire water setup(not happenin right now).

Where on the card is it, im thinkin I could get my camera in their and take a pic of it.

**Also, if it did support voltage changes by software, what software would you use to do it?? I do not want to flash the bios, incase I need to RMA

do you mean, bump up to 1.3 ish, or can you take it higher?

[KainXS]

when you say higher voltage....

do you mean, bump up to 1.3 ish, or can you take it higher?

you can only go up to around 1.3V using the vga bios on the 38XX series so you can't really take it higher, if you do it won't matter because the limit it will stay at the max it can deliver which is around 1.3V

thats why im waiting for this
