Radeon X1800GTO@XT MOD (12P to 16P)

[bchivers]

chron, sorry to hear about your card and to see you go. You have helped me alot.
I bought an opened box saphire 700pro from Newegg and it was a great card. Sold it to my brother and now my nephew is using it. I think there is a short term return policy at Newegg for opened box but I'm not sure.

Yea this thing sucks at overclocking. I can't even get it 25mhz above stock speeds. But whatever, it has a tad bit more performance as the overclocked x1800GTO.

what are the max. safe voltages for this card?

 

[Filip]

I think my memory is different. I dont know...

To edit your own bios and unlock 16 pipes do the following:

1.) Download HXD Hex editor from here http://mh-nexus.de/HxD.htm#whatsnew

2.) At line 00000070 find the key "19". Change it to "18"

3.) Save As> "New.rom"

4.) Open new.rom with RaBiT2.0a found at http://www.techpowerup.com/downloads/283
*You will get an error "Bad bios?" > Click yes and continue working on it

5.) Under "features" tab, change voltage to 1.2125

6.) Save As > New.rom > Yes to replace

7.) RE-OPEN new.rom with RaBiT2.0a. Under features tab set voltage to 1.38. You can save the bios and reopen it to apply more voltage but its best to test the bios before adding more juice.

There you go, anyone with a GTO should be able to follow those steps and get their card working 1t 16 pipes.

And then reflash bios or not? Can you exlain me how to do that?

ati

And then reflash bios or not? Can you exlain me how to do that?

I have a sapphire card and will not unlocked......i have tryayed and not working. so

 

[Filip]

OK! How much I can raise voltages of mem and gpu to work stability, and where I can raise voltages?

EDIT:

But I want to try flash! Can you tell me how? Tnx advance

 

[chron]

Ok, to flash your bios you'll need to download a flash program.

Here you go: http://www.techpowerup.com/articles/overclocking/vidcard/34

Found this rite on techpowerup's site. Be sure to follow instructions carefully. If you have sapphire card, I'd say your chances of unlocking are slim to none. The cards that unlocked the best were 'HIS' cards.

If you find that your pipes do not unlock, don't worry about flashign back as having the new bios has no adverse affects on the card.

max safe voltages (given you've got a small 80mm fan over the voltage regulators) should be arround 1.45 - 1.475.

Good luck

1. I cant find the right Bios for my card. I have 2.0 memory but I found just with 1.4 memory! Can I flash that bios(1.4ns)?

2. Where are voltage regulators? I have Zalman vf900-on card, and small blue on memory!

3. 1.45 - 1.475. is max for core!? What are max for mem?

Thanks

you can flash your own bios after you've modified it. Its the safest route:I think my memory is different. I dont know...

What is the max mem and mem IO voltages? tnx

hy guys... i have buyed the TMG AT2..... its a king coller....

sorry to inform you but thermalright hr-03 plus is the king of coolers

Seems I'm not the only one to have trouble flashing my card to an XL. Luckily for me, my card has 6 mosfets and likes to overclock. Just a shame that I can't get those extra pipelines, as they'd probably improce performance in RB6:Vegas and STALKER alot more than an overclock...
My card is an ATi X1800GTO (really... not HIS, PowerColor, nothing, it's a generic ATi version...) with an Accelero X2 (awesome cooler, dropped my temps by 10*c and keeps them at 5*c less even with higher voltages).

 

[chron]

yea ATI probably used lazers to lock the pipes. I wouldn't be surprised if you hit 730 on the core though working with only 12 pipes and all.

oh and rainbow six vegas runs like crap on the highest end systems so don't worry about it. They actually run best on quad core CPU's rather than on dual core + 8800 or something.

 

[Ripper3]

Yeah, I can tell RB6 needs higher specs. It runs like crap, even at 1024x768. My X2 4200+ is nothing to sniff at, but still runs like crap.
Actually, the core can likely handle higher speeds.
I've done loads of overclocking with it. It's almost as flexible as my old 6600 (stock cooling, managed 450/700 from 350/600. With cooling, could probably have reached 600/800 stable), but just doesn't seem to like getting its memory over 610 before throwing a hissy fit.

About the laser locking, I always though they just stopped power through the extra pipes, not that they actually killed off the pipes completely. Shame really.

Also, is it just me, or does someone else get random CTDs in most games with the ATi? I doubt it's the card's fault, as I've tried it in Linux, and it ran stable, even with Wine. Currently running NGO optimized Catalyst 7.3 (have tried from Cat 6.4 from the CD to Cat 7.4 at one point in time or another).

 

[Filip]

i have one problem. i edit my bios by your directions (00000070.....19-18), i open it ina rabit and raise voltages and flash it. new voltages are set but ati tool read 12P! where is a problem? there is SS

Tnx advance!

EDIT: Why I cant edit voltages in ATT after flashing? How can I fixed it? What are stock voltages of this card?

 

[Filip]

anyone?

 

[Filip]

Can anybody help me?

 

[pt]

is your card unlockable?

 

[Filip]

NO. But how I can fixed that I can change voltages in ATT? after flashing new bios(with new voltages and 16P, only voltages changes, 12P-16p not) I cant change voltages in ATT!

 

[pt]

att as ati tray tools?
if it's isn't unlockable, why did you flash with a 16 pipe bios?

 

[Filip]

After I flash bios with 12P, bu I still can change voltages in ATI tray tools!

 

[pt]

then ask in ati tray tools forum
this is ati tool forum
have you tried using it?

 

[Filip]

In ati tool I can! What is stock voltage of gpu(ati tool)?

EDIT:
Is your bios original, if is, can you upload me your bios?
