Upgrading Mainboard in Lecroy DDA-3000 (aka WavePro 7300a?)
analogRF:
is it not possible to have a non-intel chipset motherboard (but with AGP slot) that works with the original display?
analogRF:
I took the board out and tried to check the caps (at 20-50mV rms voltage and 120Hz/1Khz/10Khz on my HP 8263B)
but as I expected, it is really not possible at all to say anything because there are so many caps in parallel with many inductors in between
so its a complex impedance that always shows a negative (but very tiny) ESR which is meaningless although the capacitance value seems
ok but that cannot show the condition of individual capacitors... They are all Rubycon and Nichicon 105C as far as I can tell and visually look perfect to me...maybe one of the MOSFETs is open? but again it is not possible to check in circuit and desoldering
sooo many caps or mosfets is not worth the time and headache...
analogRF:
It seems the only way forward is to ditch this motherboard and replace it.
As I mentioned before, in order to replace the board I am not looking for total overhaul and a moderate upgrade will suit me the best.
Therefore, I am looking at Asus P5PE-VM https://www.asus.com/ca-en/Motherboards/P5PEVM/overview/
which accepts Core2 Due but only up to 2GB memory
and Asus P5P800-VM https://www.asus.com/ca-en/Motherboards/P5P800VM
which I think will not accept core2 due (not sure) but up to 4GB memory. But it can support up to Pentium D 960
both fit the scope perfectly and have native PCI and AGP.
Can anyone help me to choose, please?
Is Win 7 possible on these boards?
thanks
nctnico:
The P5PE seems more modern and supports faster memory.

my main dilemma is the 4GB vs 2GB max memory. which is better? otherwise, yes P5PE has better features like gigabit LAN and faster FSB
also is it possible to have win 7 with any of these boards?
