Ok this is just my theory and my opinions

This is strictly for BBA cards with vivo /rage theatre chip and 1.6ns ram.

Ok i modded about 5 of these guys all from compusa, cause those were what i had access too.

All 5 successfully modded to x800xt pe. using gigabyte bios for flash and then flashed to ati x800xt bios and then i flashed 2 of them back to the gigabyte bios. and heres why

The ones that ran stock xtpe speeds and above already had 1.4 -1.42 volts on my multimeter when i checked --- 2 cards
The ones that had difficulty reaching those speeds with stability and artifacting had a voltage of 1.3- 1.32 multimeter readings --- 3cards. I pencil modded these suckers to 1.4-1.45 and i only got about a 5-10mhz increase in core and nothing on memory. So it didnt help a thing.

Now whats funny is i thought all x800 pros had a default voltage of 1.3-1.32.

Unless (this is the theory I came up with) the 1.4 volts which are stock volts for xtpe were just rebadged retail x800xt pe. Even the memory on these bad boys could clock 15-20 mhz higher with the core running 20-30 higher right off the bat.

the 1.3v were struggling to make stock 520 and heavy artifacts at stock 560 memory.

Maybe the 1.3v croe x800's were the ones that failed the xtpe test and got rebadged.
And maybe the 1.4v x800's were perfect xtpe that was just rebadged.

this is my 2 cents and i could be 110% wrong but thats my conclusion.

sorry for my babbling
 
hey mjl,

Wanna post the serial #'s from the 2 cards that came with the 1.4v standard? The more info we get on this, the easier it might be to track down a guaranteed card.

BTW, your theory sounds correct, and is kinda what some ppl have been hinting at lately. Thanks for posting.

EDIT: the two serial batches that have been confirmed as working start with 630429 and 630430. Someone also said that cards with serials that start with 630431 are moddable, but I don't know how many times this has been verified. Actually post the serials of all 5 if you dont mind, so we can check for any trends, etc.
 
in fact, let's get everyone who has done the VIVO >XTPE mod to post their serial numbers, and if the flash worked, if it can clock past XTPE speeds, what volt it came with stock, and if you have stock cooling or not.
 
now that is the difficult part because all 5 that i got is serial # 630430. thats where the dilemma is. It seems as though its just random and doesnt matter what serials they are.
Seems like they just pack em regardless. I think you would have to get lucky cuz lets face it. Why would they even care if its a perfect xt or a failed xt as long as they both perform at x800pro standards.

I do know the 29 and 30 are moddable but i havent dealt with the 31's as of YET.

Ill keep posting after i do some more mods and let you guys know what i find.
 
My Sapphire x800pro vivo had 1.39 stock vcore. I'm currently at 630 core, 596 mem with 1.6vcore on water.

I dont' have the box anymore though, so i can't tell you the serial code.
 
well thats sucks that its luck of the draw. At least I know those two serials should be moddable in some form.

I think I'm gonna get to a CompUSA tomorrow and pick up a BBA X800 Pro. But can anyone come up with a good excuse I can use to return it if need be and get the 15% restocking fee waived? Only reasons I might wanna return it are: SLIM chance that it doesnt turn out to be a VIVO card(anythings possible), or that it just cant even come close to XTPE sppeds. Any good ideas are appreciated. Thanks.

You're buying an X800 Pro. You know you're buying an X800 Pro. If it doesn't happen to be a VIVO and mod to an XT, it's your own damn fault. You got what you paid for, so deal with it.
 
dang buddy, calm down now. I don't even know for sure if Im gonna get one from CompUSA or get one at all. Just exploring the possibilities and theorizing about the worst-case scenario. I'm not out on a mission to screw over CompUSA or any other company.

Take off those grumpy pants....
 
I got mine last week..(compusa) serial# does indeed start with 630431 I have only messed with the OC possibilities a bit.. but it appears to have some room to move.. I have been to 565/580 with no problems.. but just set it back to stock because I'm a paranoid bastard!! the whole mod thing was a breeze btw.. Best bang for my buck in quite some time!! Thanks to HardForum!! :D
 
My x800pro Serial# starts with 630428 and its has been flashed to an x800xtpe with no problems what so ever i dont know the voltage but whatever it is its seems to be working :)

Is this a X800Pro normal or Vivo model?
 
Which bridge do you jump for 1.4v?? On my 9800pro I did the Vmod using a pot. Could someone please provide a link with a pic pls? . My Powercolor X800pro 1.6ns DDR/VIVO would not run 100% stable at XT speeds after the flash. After adding a water block and 80watt pelt it runs fine up to 530/580 now. I suspect the Vcore is at 1.3v. I will put the Fluke to it tomorrow and check.
 
LOL and some guy was talking about the VIVO's didn't need the pencil trick. :rolleyes:

Nice observation, I wonder why the 1.4x ones weren't just sold as XTPE's in the first place?

you sound like a thinking man...

The above link is to do with Nvidia cards but check it out and see what you think.

Just checked the Vcore on mine. My Fluke reports 1.383vdc. Seems rather high for a Pro card. The uncut bridges, nearly 1.4v Vcore and 1.6ns DDR are making me think this is a rebadged XT. The only chink in my theory is the fact it was not stable with the stock cooling. Is the HS/fan on the XT models in any way different than the Pro's??
 
My UPC sticker says RADEON X800 PRO 256MB V/VO/D, and the Serial Number is 630430004151-01.

I'm running at 520/560 MHz, the Device Manager says it's an XT PE, and I haven't had any problems what so ever. Not sure what my voltage is, as I don't have a DMM with me. I also have Arctic Silver 5 on the VPU core. Right now I'm idling at 39 C.

Ive personally never had a card JUST die on me. The only things i got were lockups if the core was too high or heavy artifacting if the memory was too high. In either case i would just clock down. Vcore mod or Vmem mod is a different story and it could fry something but that is the risk you take. I just dont understand how a simple bios flash would kill a card ( unless you flashed incorrectly) and that has never happened to me. In either case i think the cards or card that died during the SOFTMOD were bad cards in the first place.

But it up a tad higher to 1.42 and see what happens. That might fix your problem.
 
its been said many times now that the Comp USA BBA x800 VIVO cards are anything but created equal.

heck, I've seen people who can barely get to 500/520 after soft modding while others (like myself) have had no problems at all running at 520/650. (on stock cooling at that...)

heck, one day I wanted to see how high I could take mine and it ran Doom 3 at 550/580 without a hitch but I didnt leave it at that. I just wanted to see if it would run those speeds.

heck, stock XT PE speeds are more than good enough for me so I'm definately happy. there's no sense in me getting greedy for higher speeds thus increasing the chances of hurting my card thats already running WAY out of factory specs as it is. :p
