need vtt/vdimm mod for the abit an8

[masterpain]

hi!
any news from rav286k1 yet?
i will will check the readout again if it is much too high.

Hi Masterpain,
sorry but until my friend does not return from his holiday I can't mod the motherboard.

Hi Masterpain,

no problem, i think i will keep hold on this board because of the upcoming venice cores.

Did you check the resistance with the power on or off?

Did you check the resistance with the power on or off?

power was off, iirc, i will check again, i am currentl sitting next to my mainrig, i will check again.
edit: its again the same value. power was off during measurement.

Ok, thanks for checking. If I have got the right point, there might be a problem finding a multi-turn variable resistor with a high enough value to only produce a small voltage increase at maximum resistance.

since my an8 went uo in smoke for no reason it will take a month to get this mod runinng.
@rav286k1: any news from your side?

Hei... there will be new board that features higher voltage

the ABIT AN8 Fatal1ty SLI

Vdimm : 2.55V - 3.55V
Vtt voltage: 1.25v ~ 1.75v and DDR/2

[masterpain]

mmh, nice.
i will get one as soon as its available in germany.

Can someone please solder a 100 KOhms trimmer 25 turns to pin 14 OR to pin 8 of the Winbond W83320S IC to see if it change the Vdimm?......One of those two legs (14 or 8) must be the Vdimm mod........First try on oin 8 and if it doesn't works, try on pin 14.......Beware to pre-trimm it at it's MAXIMUM resistance (ex. 100 KOhms) before soldering it.....The other Winbond IC (W83310S) with the 8 legs is for the VTT - autotracking and autocorrecting the VTT - .....So no VTT is needed for this mobo....

[masterpain]

i will try it as soon as my board is back from abit.
still waiting....


@ tictac: is this theboard you where talking about?

[tictac]

yes it is

there are also cheaper veersion with 3.55V vdimm

AN8 Ultra
AN8 SLI
