Can people with a new Gen 5 with DDR2-667 confirm using CPU-Z if Dell is using CL5 (5-5-5-12) stock memory?  I have heard some conflicting info.

 

If so, will adding a pair of PC2-5300 Ballistix (4-4-4-10) in addition to the stock CL5 work?  (ie, will it boot?)

 

If that combo won't work, is there a noticeable performance improvement removing the CL5 and just using the Ballistix PC2-5300 with 4-4-4-10? 

 

I have seen this OCZ (2x512) for $160. (4-4-4-8)

and this Ballistix (2x512) for $192. (4-4-4-10)

and the standard crucial (2x512) for $180 (CL5)

OCZ seems like a better buy and better performance....

 

what do  the memory experts here say?
