72-pin Memory

[x56h34]

What do you guys consider the safest and most compatible memory for use with Phase 5 accelerators?

I'd say that the highest chance of success would be if using quality brand name SIMMs that correspond with the bottom mentioned specs (correct me if I'm wrong):

FPM, non-parity, 2K refresh, 5V, 60ns, matching pairs for any card that takes more than 1 SIMM.

Of course, these specs are not a must, mind you, but I think are likely to work with less chance of problems. It is also very annoying that some accelerators seem to tolerate different SIMMs better or worse. :-(


Comments? :-)

Dunno, but I just bought a wicked 72pinn memory tester:-D

AFAIK, EDO-RAM is in general working better than FPM-RAM together with miggy-accelerators...

whabang:can u explain this ? . i have fpm in my setup now (2x 64megs) , soon 2x 128  ..

i have a blizzppc

and i have still 1 set of EDO simm's (2x64) and i notice nothing (both sets running at 60ns)

My thoughts too. The only accelerator which benefits from EDO simms is the QuickPak A4000 060. All the other ones do not utilize EDO's advantages, nor parity bits.

4 bit's is not in use indeed but i was referring to what whabang said about FPM (fast page memory)

i have 2 sets of diffrent simm's  , 2x 64 EDO and 2x 64 FPM  and i notice no difference when i use em and comparing (both run in 60ns with all caches on)

cheers

pps:  x56h34  i love your AVATAR!

 x56h34 , btw i hated that game for almost 10 years , last year i noticed (FINALLY) why it was so hyped up, its great though yet abit too annoying, stunning visuals and awesome playbility,,, RUFF'n Tumble

Ruff Rogers from Ruff'n'Tumble rules. 8-) It's one of the best Amiga games to this day.
