I used it recently, and can attest to its goodness.

My motherboard suddenly decided to stop working - a good month after the 
last bit of fresh hardware was added to it. memtest86 spotted the 
problem, but only just. My memory subsystem was returning *RAKES* of 
single-bit errors across the full address space, but only when you 
accessed it in a certain way (98% of the way through test #5 in memtest86).

Turns out my board will no longer function correctly with all three of 
my DIMMs installed, but is 100% happy with any two of them. My best 
guess is a resistor or something got cooked out of tolerances. I let my 
case temp creep a little higher than perhaps I should have. I haven't 
tested with other DIMMs yet, nor clocking back the PC133 CL2 RAM to CL3 
or even 100MHz.
