hello,

im very new here but in the PCGHX Forum no one knew if anywhere a XFX HD 5450 exists so i want to ask here

the Chips are: top 8Pin: Pm 25LV512 zu dem: http://www.alldatasheet.com/datashee...PM25LV512.html

near the PCIe slot: APL5920 VN4DZ nothing found

near the internal VGA:APW7165A A01G4 nothing found

near the DVI port (14Pin):

HB125 1AKG4 CDKT nothing

 

Sorry this is all the info I can get you hope that you can help me

Few pics of the card are attached.

If you worry abot the cooling me and Roman(der8auer) are planning something with air cooling but something veeery special and strong

 

 

TIA

For the memory vmod, it looks like FB on APW7165 is 6 and GND is 3.

However, from the OCN competition we did a few years ago with these cards, extra memory voltage really didn't help.

 

If you could get some better photos of this, it would most likely help a bit.

Ok thanks I thought that the mem wouldnt help much and its only DSP mem so not the best OC mem if it had been Hynix, it would be much better with the pics i will take them tomorrow but thanks alot for now.

i thought that the Pm 25LV512 would be the VMem Controller

i also have a Guide for the Gigabyte HD 5450: http://www.overclock.net/t/696166/gigabyte-hd5450-vgpu-vdimm-mod

But its a different layout also i will check the resistance between the Pins it was resistance*20=Poti., wasn´t it?

Rfb*20 = ~Rvr where Rfb is the resistance between the FB pin and ground and Rvr is the resistance for the trimmer pot.

 

So yes, you're correct.

Ok for the Pins that you gave me it were 7.29k Ohm so i Would Need a 150k Trimmer Pot which I adjust down

Later I will Attache the pics

 

So i have the Pm25LV512 in the Pic(if you Can't read it 2.2 k Ohm so a 50k Trimmer Pot)

looks like the IC for GPUv is one of the 2x located on the back side just above your vendor sticker.. what are the IC #'s there?
