X1300 Vgpu Mod!!

**Lightman** · 12-19-2005, 03:00 AM

Finally i make my vgpu mod for x1300 non-pro and with slight 0.05V incrase i get extra 40mhz on core!!

Before my mod i was able 570mhz MAX on gpu but now it is 608mhz

Of course this is only beginning

here is screen

just to let you now:
- normal voltage for gpu on x1300 is 1.25V!!
- there is one resistor you need to change on pcb but it is very small! (0.5mm)

I will make howto later because i must go to work

X1XXX arent all softmodable ? :S

No

for now only X1800 and mayby x1600

WHoa! Run 3d Mark05

What's the score gonna be ?

here is the answer!!

and mark01

remember that this is sapphire x1300non-pro

Nice results , can u OC it more or is this the highest OC what u can get ?

yes i can more but this is stable for now!
and if i want better scores i can tweak drivers to preformance mode
and this is only with slight vgpu incrase
mayby tomorrow i will give more volts to my rv515

(and RAM too)

**saaya** · 12-19-2005, 11:22 AM

nice!
cant wait to play with my 1600pros

ordered 2 already heheh

those are very nice scores for a single super low end card!
here 1300pros cost the same as 1600pros though, wich have 3x as many pixel pipelines...

**bassv2** · 12-19-2005, 11:31 AM

I wonder how far this thing could be pushed.... it's arleady past Pro Stock Speeds

here 1300pros cost the same as 1600pros though, wich have 3x as many pixel pipelines...

And 3x more heat

**Lightman** · 12-19-2005, 11:53 AM

to bassv2: i hope to get 700-750mhz from gpu on 1.45/1.5V and with x1300pro card after vmod should be much better!!

to saaya: power reg. on x1600 is same as on my x1300 (rt9232a) so vmod will be easy if you can solder so small resistors 1.0mm x 0.5mm

what MB you want to use for xfire setup??

nah, non pros are 15W and 1600pros are 35W or so... afaik

i hope i can use the mod on my cards! right, you have a sapphire card as well! perfect!

i hope i can get 750 on my 1600s! ^^
i dont know if i can solder that well, lets find out

and atm i have a crossfire board from ati for a crossfire review, and next week i wanna buy the asus a8r-mvop, only 100€ and its very fast i heard.

It's more than certain that you will get 750mhz from x1600
i want asus too but is unavailable in UK for now, mayby after new year

now i'm looking for some good pictures of my card over internet, because my camera will come wednesday and i can't show you where to solder

Mayby someone will send pictures of x1300 back side in macro mode??

Lightman,
what cooling are you usiung?? Do you have any idea what the temps are?

passive!! it's enough for now!!

i install fan on it but with no effect on max clock of gpu

ad2. temps are quite normal, i can hold radiator in hand without problems it's only warm. i think gpu is around 60C

**Unoid** · 12-19-2005, 01:53 PM

throw 1.3V on the gpu and tell us how far it goes

**Lightman** · 12-19-2005, 01:59 PM

it's allready 1.3V, default for x1300 is 1.25V!!

but i will throw 1.45V or 1.5V in this week, for now i'm looking for some shop with electronic parts in london

**saaya** · 12-19-2005, 02:12 PM

here you go

thi is the default pcb from ati, i think sapphire made those cards for ati so they probably used the same pcb

**Lightman** · 12-19-2005, 02:47 PM

So...

R610 is responsible for vgpu on my card it was 385ohms and i changed it to 335ohms, result - 1.3v on gpu

you can measure vgpu on 2 pins from capacitor where i put 'R610'

i think r710 is responsible for vmem but on my card is different power circuit for mem

Good fan with modding

**saaya** · 12-19-2005, 03:45 PM

so you removed the resistor and it gave you a boost?
or replaced it with another resistor?

what if we lower it even further? how high will vgpu go with this mod?
what do you think?

and yeah, this is actually the 1600pcb afaik, not 1300. ati just used the same pcb for bothb1300 and 1600, see how it has gddr3? no 1300 will ever have gddr3 ^^

they made a new pcb for ddr1 and 2 now i think.
1300 has now ddr1 and 1600pro is ddr2 pcb, hence a different power circuit to feed the memory... thats what i think at least

what temps do you get at stock, and oced to 600 with vgpu mod?
are you still on stock cooling?

**althes** · 12-19-2005, 04:48 PM

that is a sweet mod

AFter Market Cooling!!!

I have the sapphire passive heatsink. I'm going to place an aMD 64 3000+ Stock Heatsink's fan about 1 feet away from it. I hope it's going to help temps

before I oc :P

well how hot does the heatsink get?
and how hot are the reported temps in the driver?
or doesnt it report temps?

X1300 Non-Pro dosn't have temperature sensors

I did a small OC, 500/300, and after load for about 20minutes, it was just warm... the room temp is around 10C. Being lowend, I don't think it's that hot, but when I oc more, I don't wanna take risks with no temp sensor.

I have the sapphire edition which is a black passive heatsink.

**saaya** · 12-19-2005, 06:16 PM

10°C roomtemp? omg!

geez, arent you freezing to death?
its -2°C outside but even with an open window for a few hours my room temp doesnt drop to 10°C!

and yeah, better get some air pushed over the heatsink.

lol, I hate it when It's hot, and I love my computer

If it's cold I just wear more clothes, computer can't wear less
