I can overclock more my memory but i dont want crap it ! I wait for my new gpu cooler ... after that i will think to overclock more my memory The X1950 Gt are not better than the X1900 gt because the gpu are an R570 for X1950 an for the X1900 gt is an R580 ...

The x1950gt can do internal crossfire, I would say that is better. I have the r580 core and I can say I wish I had the R570 X1950 pro 512mb that I originally wanted. Still I am happy with what I got. If you really want the x1900gt go to ebay they have a ton of rev 1 cards that clock better than rev 2. Oh and the R570 was an original designe, the R580 on gt cards are ones that couldn't make it as XT's.

LOL ! AN X1900 GT Can be an X1900 Xt lol just overclock it i do benchmarks and i only had 600 pts less than the X1900 Xt so if i had an better cooler i can overclock it more :rockout:

I have the same core; overclocks just a few ticks but my memory goes up alot, just depends. Use ATItool but do slight increases, we have the same core and the overclock tolerance on rev 2 cards is very low.

IModAmd · May 8, 2007

Use Ati tray tools

Does that card could be bios modded?

IModAmd · May 11, 2007

It's depends of wich you had you can mod the bios for up the voltages the clocks and etc but mod the bios for unlock something i dont think

Is rare somebody can unlock the pipelines

STEvil · Jun 2, 2007

My core reports as R580 XT2 in ATi Tool 0.26... BBATI X1900GT.

How do I dump the bios in XP-64? RaBiT doesnt work.

Clocks ok.. 648/900 1.375v/2.088v stock cooling, but runs hot!

Wile E · Jun 2, 2007

You can use ATItool to dump the bios, iirc. Don't know how you would read it tho. Might want to search around for a newer version of RaBit, maybe there's a beta with x64 support?

And, not to rain on your parade, but I think only like 4 or 5 members successfully unlocked. The chances of an unlock are very slim to none.

Smokabowl · Sep 23, 2007

When I opened my BIOS in RaBiT, this is what I got.
R580 XL A22 BIOS

So I post it and wait for somebody to post a link for drivers? I really want to be able to get those extra pipelines.

theonetruewill · Sep 23, 2007

Read the first post. It says if you have the R580 XL core then don't bother.

Ohhhh, I thought if it was the PRO dont bother. Thanks =]

Well, the memory ain't shitty. It clocks far in excess of my rev. 1.

ajsasr · Sep 23, 2008

Lots to Read..

If anyone is still monitoring this thread, I just wanna make sure I have all what I've read right. I've got a used Rev 1 of the card coming to me today.

1. If I have 580 Pro, then I can unlock 4 additional pipes and mod voltage, and OC with Atitool.

2. If I have 580 XL then I can't unlock and all my OC will have to be done via atitool.

If 1 is true for me is there still anyone around that's modding the bios?

Thanks.

IF YOUR GB_PIPE_SELECT IS 0x3FE4, THEN YOU CAN UNLOCK as it says in the threat im sure if you get in touch with tofu he can do it for you

Nick259 · Oct 17, 2008

would this work with an x1950gt?

KainXS · Oct 17, 2008

no, the x1900gt has the R580 core that the XTX has but the non XT/XTX X1950's only have the R570's
