I have a problem using readyboost, i have a 512mb and a 1GB memory stick
which are both formatted and when i try to use them as readyboost it says
that they do not meet the specied specs, what can i do to reslove this?
 
Try using the usb ports on the back of the computer. If you are using a usb
hub it should be a powered hub.
 
You could try pluggin it into other USB ports, some people have found that
they have to plug and unplug it a few times before it works... You might
have to buy new USB memory sticks which are fast enough to meet the specs.
As of right now, I do not know of anyone composing a complete list.

I am using the PNY Attache 4GB. I have read the Sandisk Cruzers also
work.There are a few others here who have given brand names of ones that
work. Just search for ReadyBoost.

Here is what speeds are required:

Q: What perf do you need on your device?
A: 2.5MB/sec throughput for 4K random reads and 1.75MB/sec throughput for
512K random writes

Q: My device says 12MB/sec (or 133x or something else) on the package but
windows says that it isn't fast enough to use as a ReadyBoost device... why?
A: Two possible reasons:
The numbers measure sequential performance and we measure random. We've seen
devices that have great sequential perf, but horrible random
The performance isn't consistantly fast across the entire device. Some
devices have 128M of lightning fast flash and the rest of the device is
really slow. This is fine for some applications but not ReadyBoost.

My PNY Attache 1GB drive doesn't work, apparently it doesn't have the
necessary performance characteristics :-( Could it be my USB ports aren't
up to the job?
