Upgrading Mainboard in Lecroy DDA-3000 (aka WavePro 7300a?)
nctnico:
2GB should be more than enough. And I wouldn't bother with Windows7. You probably bring more bloat on-board.
analogRF:
I just managed to do some measurements on the motherboard and the cpu is actually getting no power at all. that's why the bios does not run and no beeps whatsoever.
the source voltage on the mosfets near the cpu are all zero and some of them have 12V on their drain but some have no voltage on any of their pins!
maybe the dc-dc converter IC is dead ... whatever that chip is... or a mosfet is bad (not shorted because I checked them for short but i cannot check for open in-circuit)
analogRF:
does having a dual core or quad core intel CPU actually boost the performance in Lecroy Xstream software? how significant is it if any?
for example does the waveform update increase or the spectrum analysis really gets faster?
I mean between a dual core and a single core cpu with similar clocks
according to this blog http://s-audio.systems/blog/lecroy-upgrade/
having dual core has a minimal effect.
can anybody on this thread who have used the scope both with single and dual core cpu confirm?
thanks
Mechatrommer:
confirmed, dual core is better (through "the feeling", its more noticable in 3D view) but... "minimal" is a subjective term, if you expect twice the speed then... no.
analogRF:
no of course I dont mean doubling the performance but does the scope really use both cores to a large extent when it is put under stress like heavy spectrum analysis and other maths?
That blog that I posted earlier says no it does not. So I wonder if it is better to have a higher clocked single core than a lower clock dual core
