I bought my Inspiron E1705 with 1 Gig of dual channel 533mhz mem. Realizing this was a mistake i did my homework and found a good set of dual channel 2 gig 667 mhz. Memory works fine, I'm getting a lot more performance in Vista, however, the clockspeed is only recognizing 533mhz. I know it's a knitpicky thing, but I did PAY for the faster ram. All the tech specs I've found tell me this machine will take 667, but I can't find an option anywhere, nor is it automatically detecting it. Any help would be appreciated.
