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

[hagr]

Ive got the same problem... I also have a PowerColor Radeon x1800GTO, that I managed to flash, but I wasn`t able to open the 4 last pipelines on my card... Ive got GB_PIPE_SELECT 0x12BB4 on mine... I have overclocked it pretty well tough... Core: 700 (730 max. ) and mem: 850 (860 max.) with stock cooling and Omega drivers... can`t get so high with the ATI catalyst drivers, I don`t know why... and my voltages are about 1,4V on the core and 2v on the mem... I`m very happy with those results... Just bought a new VF900-cu for my x1800GTO for christmas gift... I hope it likes it

ATI Tool list my chip as a R520 LE. What does the LE stand for?

 

[JC316]

The LE is the core number, it means that it's 500 MHZ and 12pipes. The R520 thats in mine is 625 MHZ and 16 pipe. It dosen't mean that you can't unlock it, it's just the name of the core.

hey what are the default voltages for an x1800gto?

 

[vitesse]

The default voltage for my Powercolor x1800gto is 1.10v for GPU.


It's sad that I fail to add the 4 pipeline because I have a new Sansung 40" lcd 1080p screen and game, video (SDTV / hdtv) and windows desktop look realy great on it, but game run a little low in fps (15-30fps) it would be nice to have give my card a little bit of power.

is a saphire x1800gto with:

GB_PIPE_SELECT 0x227E4 (not 0x27E4) unlockable?

thanks

try rivatuner or atitool to soft unlock the pipes (cant remember if either of these allow that - i do all my mods the hex way ) if it can be unlocked, see how high it can oc with the extra pipes

it has to be flashed for the pipes to be unlocked
and just some cards (HIS mostly) unlocks

halooo....
i have grandmars ati x1800 gto 12p
i have try to make it 16p but fail. i also try download the file whos post it in internet also can't. pls help

thank u

You can't unlock that core .

 

[Zubasa]

Grandmars are really quite dangerous cards....

Here's a question: my card has the GB_PIPE_SELECT of 0x6E4B. Is this unlockable or not? When I searched, I pulled up results that had to do with the x1900 for some reason.

Unfortunately your card also can't be unlocked .

Is there really nothing he can do?

Dude try applying a basic X1800XL bios to it, if it doesn't show 16 pipes then I'm afraid it won't be able to unlock it.

Ok, so if:
A: You unlock it with an x1800xl bios, modify your X1800GTO bios to have 16 pipes (I've posted instructions on editing your own bios, just search for all posts by me) Modding an X1800GTO bios is probably better than just applying an x1800xl bios.

B: You CAN'T unlock it, ATITool .26 will allow dynamic voltage controll which should allow you to overclock that thing greatly. If you try 1.25 to the core, 600/600 should be fine. If you manage to cool the voltage regulators properly, 1.425v core, 2v mem might give you 700/800

If the system locks up at anything past 1.3v to the core, it probably means your card has 5 mosfets instead of 6 and that kind of power is impossible

Either way, you've got an ok card. Enjoy life and don't stress over what other people can do with their X1800GTO's that you can't.

and from out of the wood work comes Chron....lol...listen to this guy, he has atleast trashed one card in order to learn for us..never set your bios clocks too high..lol..i learned howto from his thread..ty chron.....

You're cool

 

[Fast240Z]

Thanks chron. I've tried flashing it with the x1800xl bios, and hex editing my own, and to no avail. You're right though, I have been able to get some amazing clocks out of the card, but alas, it does only have 5 mosfets. But overall, it spanks my x1600pro up and down. Thanks!

What are acceptable temps for a HIS X1800GTO?

What are acceptable temps for a HIS X1800GTO?

Well I read that the core has a max temperature of like 120C, BUT once it starts gettin to 90C it heats the mem chips up and causes memory artifacts.

My recommendation is to try and keep the core under 75, as well as your voltage regulators(VR). I've got a VF1-Plus, and although it doesn't fit EXACTLY, it does fit without any modding and does a great job. On the end of the card I have an 80mm fan running at a silent level on top of the VR's, attached with bread ties to holes in the card.

The fan over the VR's made a HUGE difference in temperature, even when the fan was on a low setting. My own VR temps idle at 47C, load 60C with artifact testing. Core temperatures idle at 53C, load 70C in the same stress test.

I'd say the max safe temperatures would be 80C core, 75C VR. Anything beyond 90C on the VR and you could actually melt componants in the mosfets.

This is all personal opinion also. I'm sure there are people that are comfortable with higher temeratures, but this is my own comfort zone. GL

BTW my settings are 1.45v core, 2vmem, 16 pipes, 700/700

Chron, I used your volt mod idea, and I upped the cpu to 1.150v and memory to 2.001v, which yielded a speed of 607/702. I ran 3dmark06 with stock clock and voltage, and scored 3232, but after my overclock and volt mods, I scored 4204, with no artifacting!

lol tight

 

[bchivers]

Chron, thanks for the info.

welp, I broke my card >:/

I was fiddeling with the cooling and nocked off a little transistor or whatever it was. After soldering it back on the card still had no output! Also, the heatsink never got warm so I think perhaps something shorted out or whatever fell off controled voltage somehow and the connection won't ever be the same.

I've decided to purchase a sapphire X1950XT 256mb (250 at newegg, not that bad)... I was so sad to see my money saver die like that (and all because of idiotic stupidity on my part.) I checked newegg and they have an open box HIS X1800GTO but just before i completed the transaction they notified me that open box items are untested. Then it occured to me, it's probably a dead card, and it also occured to me theres a pretty high probability its the dead card i sent in!

I'll check back here every so often but I think the days of unlocking pixel pipelines are over and this was the last line of cards to do so... I hope everyone knows they can PM me with questions on this thing.

Open boxes are tested for functionality. At least that was the story I got from my two open box items. My X1800XT was open box and it works great. Sorry to hear about your card, but at least you got a great card in it's place.

250 is almost what I spent on my X1800GTO also, so I'm still at my 250 a year mark. Maybe Christmas of 07 will be a DX10 card.

I gotta cool it with spending money on pc stuff! I just bought an e6600 last week.

You sound kinda like me, I will upgrade very rarely. I just got a shiny new Brisbane, mobo and Ram and thats the last time I will upgrade for a WHILE. I will probably upgrade again in late 08 to early 09. I have to watch myself to make sure I don't get into the "tech race".
