VMOD or Unlock Pipes on X1900GT? (NEW VERSION)

veckans · Sep 20, 2006

I have the new version of X1900GT (Powercolor) with no overdrive and a new cooler. The stock speeds are at 513/1314MHz. There are no voltage settings in ATI Tool for this card (I am using ATITool_0.25_b16pre3).

A picture of the new card (Sapphire):

Does anyone know if this card has unlockable pipes or has any way to increase voltage? Cause right now its a really poor overclocker with only 540/1404MHz reached stable (my old X1900GT did 621/1620MHz at default voltages).

GB_PIPE_SELECT is 0x227E4

Here is a BIOS dump from ATIWinflash:

EDIT: I removed the cooler today to take a look at the PCB.

The core is still R580

Voltage Regulators? (the 3 small chips with cooling near at the power connector)

read this, plus remember these cards are pushed to the max pretty much on there stock settings so any overclock is great.

My card has a new pcb design. RaBit cant place a name on the bios (XL or PRO), and ATITool cant access voltage settings. I need some fresh info on this because this is a very new card on the market.

ownage · Sep 20, 2006

I have this card to, its a new design. New PCB and other cooler.
The voltage of the GPU is 1,1v, which is lower then the old GT's.
The new versions clocks like shyte. Atitool has trouble with this new x1900GT, and voltage control won't even work on this card. I think Atitool can't handle the new PCB.

http://xtremesystems.org/forums/showthread.php?t=116002&highlight=weird+x1900gt
look at the pictures, the new GT is much different and has also lower clocks.

SO, has anyone made some nice results yet with this new GT?

veckans · Sep 20, 2006

I am thinking about trying my older Powercolor X1900GT BIOS on this card to get access to voltage in ATITool. But since its a new PCB the older BIOS might wreck the card. And i dont know if its a rv570 or rv580 core on my card.

My card looks just like the one in the xtremesystems link.

ownage · Sep 20, 2006

Its still the r580, but the lowered the core because of heat. the vcore is also lowered.
My card only will only be 68 degrees on stock fan at 70%, so this new GT stays alot cooler then the old GT's.

But now we need a new ATITOOL which can handle the NEW GT.
I tried every beta ATITOOL 25 but the all dont work and i can't get voltage controle.
As everyone else i only can get around 540 core speed, probably because of the low core voltage. So W1zzard has some work to do to get the new x1900gt working :rolleyes:

Changis · Sep 20, 2006

why don't you pull off the heatsink and check? nothing makes you more certain than when the info is physically etched into the hardware

Changis · Sep 20, 2006

ownage: are that load or idle temps? with stock heatsink it held about 40-45(c) idle (no fan editing) but now I have Accelero X2 and VF900CU (VF900CU the better cooler but may be a tiny bit noisy compared to the X2, both @ max, but then again, that may just be me))

ownage · Sep 21, 2006

68 degrees when running ATITOOL artifact scan for mor then 25 minutes.
ATITOOL is the best tool to heat the card up.
When playing Quake4 the card gets only 61 degrees, which is really nice i think.
Tommorrow i will put the Accelero X2 on the card.
I know for sure the new x1900GT still has the r580 core 'Changis'.

These cards arent pushed to their max, mine(and many others) cards have gone from out of the box to 700mhz+ core instantly.

Ray Adams newest version of ATi Tray Tools will handle the clocks and voltage adjustments perfectly. I fought like hell to get Wizzards tool to work with my GT, but it simply wasnt going to happen in this most recent beta. He'll get it fixed though.

I have the "old" GT, and it idles below 45c, and under load hasnt gone over 56c....this is all with my voltage pushed up to 1.4v.

So.......your statement is incorrect.

veckans · Sep 21, 2006

micron! My "old" X1900GT ran at 60*C idle and 80*C load. 2 other owners (with sapphire x1900gt) that I know had an idle temp at 68-70*C and load at 85-90*C. Thats also what Ive heard about other X1900GT's and XT's are even worse.

Maybe its your HIS that has a better cooler than ATI's?

And another thing, where can I find the voltage settings in ATI Tray Tools?

Frick · Sep 21, 2006

That's the reason HIS is so good. They don't use stock cooling.

Babelfish this link, this ram is rated 1320Mhz default - 1600Mhz OC.

Hello, mine is getting 580 for the core and 740 for the memory.

Under the default frequencies I reach 9300 in 3dmark 2005

@ 580/740 I make 10300 points:

At stock cooling in idle the temp is approx 70°C. I found this "hot" so thanks to Rivatuner I upper the fan speed from 25% till 35% (still inaudible) and the temperature is 45°C

But I can't tell you of some pipes are unlockable.. I tried to overcolt using Rabit but no succes....

That is what i find so strange. This ram should be able to do 1600MHz on default voltage, my older powercolor reached 1620MHz at default voltage. But on this new card i can only reach 1404MHz stable.

The default voltage for the memory on X1900GT (rev1) is 2.089V i think. I heard somewhere that this new card only gives 1.84V, if thats true it explains the low OC. I wonder what the GPU voltage is on this card?

You're right!

Theres no way to adjust voltages in the latest version of ATT, not for this card. At least I havent found any of those settings.

bad HSF application, simple as that.

as to the "new" GT issues. it looks to be a simple case of a modded bios for lower voltages to reduce temps. cross reference the card with original and if there are only minor differences, 90% chance its safe to flash away with the old gt bios

ownage · Sep 23, 2006

I compared the old GT bios with the bios of the new GT, and there are some differenses.
Maybe its possible to flash the card to the old GT bios, or we have to wait till ATITOOL can handle this new PCB.

I just got this card back from an RMA so I wont be the first to try. And, theres a lot more voltage regulators on the older model. Theres a chance it will work but not too big in my opinion. Especially not since it doesnt react to voltage changes done in RaBit on the original BIOS.

largon · Sep 23, 2006

The new GT has a digital voltage regulator the old bios wouldn't be able to control. Flashing the new GT with the old GT bios would without any doubt kill the card.

pluto68 · Sep 23, 2006

But what is the core & memory voltage on this card ?, ATI Overclocker say's 0.850V on core and 1.80V on memory, occasionally 2.15.

There must be a program that can read voltage from this card ? the bios say's nothing about the voltage.

I'm really confused about this card, i'm actually a n'vidia guy, this is my first ATI card and it seems that i was the lucky one
