- While I understand your concern, you kind of just have to "risk it". The point
- is that I personally have never bought a bad SIMM module. I have seen bad
- modules in a number of machines, but they are definitely the exception rather
- than the rule...

- If you've got a 486/33 or better go for 70ns rams (if 50 then you could get
- 60 also, although it's not really necessary...I use 70s in my 486/50). Buy
- them from a place that guarantees them and tell them you are running OS/2.
- It is no secret that multitasking OSs excersize your RAM pretty hard...even
- Windows has been known to be an uncoverer of faulty ram chips, so its
- really no big deal. Normally if you tell the people you're buying from that
- you are getting parity errors, they'll believe you.
-
- The bottom line is, don't worry about it. Just buy RAM that is fast enough
- and make sure they have a guarantee (I have seen a number of chip dealers
- that offer lifetime warantees so this is no biggy).
-
- Good luck...
