A1200 accelerators - all have timing issues??
« on: June 01, 2014, 07:33:57 AM »
I suspect the problem I am having with my A1200 (Rev2B motherboard) and  the 1230-28 accelerator is due to timing issues.  I have read that to  resolve this issue it requires removal and replacement of some  components on the A1200 motherboard.  Not sure exactly what is required.

My question is, has the designer/manufacturer corrected the timing  issues with the newer accelerator cards?  Such as the the 1220 or 1232  accelerators?  Or do all A1200 (Rev2B) motherboards require the mods to  correct the timing/crashing issues I'm experiencing with mine?

Any help greatly appreciated.

Thanks for the reply Lurch.  The strange thing is my motherboard was recapped last year according to the sticker inside it when I got it recently.

Is it just the older revision from ACA, or even the newer version all have issues?

Are their any accelerators that don't have this issue?

Does anyone have a link to the mods required to the A1200 motherboard to correct the issue with the ACA accelerators?

No I never have removed a SMD component.  Do I just heat either end with a small iron tip and use solderwick, then pry the component off the board gently?
