Maybe you can define all the terms?

I'll take that as a suggestion and define those terms as I write the Vmod Article here. Anything else that may be needed in the article? it's based on this one here your input and suggestions are welcome ....

What is the best x800xl card to get for this mod thats $300 or under? The ATI version ....powercolor version, or what?

Thanks!

Mussels · Mar 30, 2005

Hope you're still around urlyin.

got me a powercolor X800XL here, and decided to test the voltages rather than the blind way i did it with my X800PRO last time.

stock voltages read off as:

GPU: 1.43V
VDD 1.83V
VDDQ 1.90V

they dont seem to fall in line with whats in the article, so i thought i'd post and see what you think.

OC on these voltages (stock cooler) is 444 / 534

edit: My stable OC seems sporadic and changing every boot (might be room temp changing) so for now ignore the OC numbers.

... the numbers in the article are just examples... given it covers three different models and of course three different cores ... why it's good to write your default voltage and ohm readings down first, before you vmod. With the wide number of variants coming out from the OEM manufactors deviating from ATI reference builds I'm sure we'll see various readings...

But overall it'll be just like your X800Pro ... take the same precautions and post back with your results ... you did a great job on the Pro, I don't see why you wouldn't again

jep i sold my connect x850xt and bought club 3d x850xt ....jep and this is the result mark05next is the pencillingtime :rolleyes:

Mussels · Mar 31, 2005

its a pain in the ass, but i cant get it to work. i blame my pencil.

i tried with VDD and it lowered resistance there, but i erased it (not upto that yet, no ram cooling)

basically i can cover the thing in so much lead that i cant see the gap where the resistor should be, but it doesnt lower the resistance at all. is there a better kind of pencil than a 2B?

Well I've seen a couple of people say the same Mus ... But there are many that have it working ... with the card out check the ohm reading with the red lead on pin 17 of the 5420 and the black on ground... check the solder pads for the same reading or any resistor that is along the trace from pin 17 that match that ohm reading ...

Mussels · Mar 31, 2005

i used the ones in the pics, and no matter how much lead i used i cannot lower it. if you know of another pic with other resistors to try, or a reccomendation for a more resistant pencil, let me know...

But did you check the readings in the last post ..

Not a bad score ... 6754 for a stock card ...

Mussels · Apr 2, 2005

no i havent, i find it hard to find anything without a pic pointing to it. i was working with w1zz to find another measure point because it seems the resistance is too low on some cards for a pencil to have an effect... ask w1zz if he's found anything

Jep i thought that there is no reason to change connect to club but this time it payed the price.In mark03 the was lot of artifacts in this score ..mark03..,but in mark05 not soma many....weard.Next i will try to do the pencilmods for vgpu and vdd and i hope they'll work better than in connect-card :eek:

Ok I'm still fixing a cock-up. Could someone with a working card please check whether in the second picture (the 1st detailed one (for the vgpu mod)) the bottom righ leg and the two above it of the big chip in the center should have 0 resistance between them. Your help is much appreciated.

Gollu ... count the pins out ... which pins

Okay I borrowed a friend's card and sorted out what goes where. It was a bit of a mess but I think I've got it. What is the default reistance between the 2 pads on an x850xtpe for the vgpu mod?

it can vary from card to card but if you measure the resistence from pin 17 and ground on the 5420 to the left of the solder pads should be correct

GoLLuM4444 · Apr 4, 2005

5240 u mean

And what do you mean? You say that if I measure it at all it will work?

daysleeper · Apr 4, 2005

still same,i can't get these pencilmods working.i have scratched with pencil like hell but no raise on volts.cgpu stays at 1,4V and vdd 2,09V....damn :confused:

...i scratch r311 for vdd and between 2 solderpads for vgpu....

Mussels · Apr 5, 2005

its because the resistance is so low between those points, the pencil has no effect. w1zzard is working on new points to try, but he's waiting on a PCI-E card to test it all out on.

patience should help us out here, i say wait for him.

W1zzard · Apr 5, 2005

i say dont wait and try things yourself .. the chance that i find some points is very small

Mussels · Apr 5, 2005

and im sure the odds on me stabbing my card with a pencil helping my OC are great. [/sarcasm]

we need someone with a clue to do this, urlyin?

I found a beauty of a card here. I only have the Vcore and Vmem at 1.65 and 2.16. On ambient water. $450 Sapphire X850xt non pe. The clocks for 05 are 714/645, and 03 is 711/654.
