Ayoo....mine is 3.3ns only....rated 300MHz max cannot do much
Still having problems with my AGP slot. When I increase the voltage, the 3.3V rail will go like crazy on the card, but when I measure directly from PSU everything is OK.....I guess my mobo is not supplying enough current to the AGP slot since I already remove the AGP current booster mod.
Maybe need to supply 3.3V directly to the card from the PSU.......

updated shah..more update!!
rugi xanta nf7 aku..

hi bro, do u hav any idea for modding my old graphic card - gforce mx440?
can make it?

Sorry for the late reply....

Every graphic card can be voltmodded. You just have to find out how. I'm not sure how to voltmod a gforce mx440 because I never have one.

But if you have some pic of the card, we can start from there

Have you guys seen a 9550XT with a power connector??? I have one in my rig





That's a modded floppy power connector. Instead of supplying 5 & 12V, it is now supplying 3.3 & 5V (modded from the psu). 3.3V is for the Vgpu regulation circuit and 5V is for the Vdd regulation circuit. Both supply line is soldered to the input capacitor of each regulation circuit.

Results later......hehehehe

ha.... with all this toying uve been doing with ur card...make sure none of ur small caps fall off again man...

Dgn terdampar nya wayar direct dari psu tu, aku pun nak tanya soalan ni kat ko shah...

Boleh ke ko buat camtu untuk graphic card PCI-E?

I've been very careful this time.....hehehehe

Semua graphic card pon bole buat, tapi kene tau laa kat mane nak solder. Lepas tu tak tau la ade mendatangkan faedah ke tak

Tapi untuk graphic card aku mmg berkesan la. Mungkin mobo nie teruk sikit.....tak supply cukup current kat AGP slot

kesian.. tengok my ex-GC .. kena rape LOL

halo, ur fx5200 is 128bits or 64bits? wut brand? i doubt is there any different to vmod between 128bits and 64bits. i noe most of the 128bits is done by connecting vr to pin 6 and pin 9 of the ic to ground.

My card, MSI FX5200 128MB 128bit.

Voltmod does not depend on bits, it depends on the IC used to control the voltage on the card.

I'm having a very hard time overclocking this 9550XT. Every time I upped the Vgpu, the ram clock went way down .....I've read about this problem somewhere before but forgot where.....it has something to do with Vddq.

With 1.6V Vgpu, I can get 570MHz but then the ram clock have to be drop to 270MHz . Now Im only using 1.48V, the GPU is at 500MHz and the ram is at 330MHz

Arghhhh......I hate this 9550XT Rev 2.1. My 9550GT clocks to 600MHz easily

Currently, this is my best score

huh??? thats it?? even ur vmodded GT could do much better than that man....damn..

have u put back the AGP vmod yet?? mebbe the extra boost to the slot might help?

Yeah....my previous 9550GT can do better than this
I don't need that AGP mod anymore because I soldered the 3.3V from psu directly to my card.

Done some research and it looks like the Rev 2.1 9550XT GPU really sucks Older revision seems to clock higher. I think they put some reject 9600XT core in Rev 2.1

Spend my weekend poking my card with my multimeter and found another Vmod. To be honest, I dunno what this voltage is for but raising it help me to get better OC. I think I'll stop playing with this card before I kill it

Here's the mod that I found. This voltage have something to do with the ram. But I'm not sure wheter it's Vtt or Vref or something else......I JUST DO IT
The higher you set your Vgpu, the higher you have to set this voltage too or your ram overclock will drop.



And here's my latest score at 520/340....(bole la, naik sikit ) I'll use this for 24/7

keep it up shah .. i know you can do it

if success, next time help me mod my cards too.^^ keep it up. gambate.

Shah gile mod graphic card...

Apa kata kita semua share duit, suruh budak ni mod satu graphic card pci-e, pastu kasi kat aku gc tuh...

huhuhuh...

joking only...

dia tuh memang giler...haha!
gc tuh dia simply guna DMM cucuk sana sini pun boleh cari voltage utk mod...haha!
saya pun tak begitu berani...haha cucuk nanti salah lubang, semua letup...haha

Thank you guys for your support.

Maybe I'll sell this modded card and buy another card to play with . But I'm afraid no one will buy this card full with soldered wires

maybe u can giv them some waranty for the vmod...lol but not included if they blown the card by overvoltage...
