Hi people, 

Since dell supports does literally nothing if you machine is out of warranty, literally nothing you just can't ask which clockspeed is compatible with your motherboard. Its really funny though. 

Therefor I'm asking in the community since you are normal people and dell just a company for money not customers. 

I have a old old vostro v130,  . I has a 2gb 1333mhz ddr3 ram in it and just one slot. Now I want to upgrade the ram to 4gb, but I dont know which clockspeed my motherboard supports. The sheets are saying different things and the clockspeed from the ram where it is delivered with is saying different thing.

https://www.intel.com/content/www/us/en/products/docs/processors/core/core-technical-resources.html  scroll down to mobile, you find datasheets there those are the chipsets:

https://www.cpu-upgrade.com/mb-Intel_(chipsets)/ you has to go to bga1288

The manual (https://downloads.dell.com/manuals/all-products/esuprt_laptop/esuprt_vostro_notebook/vostro-v130_reference%20guide_en-us.pdf) says Single Data Ram is 800MHz so you would say Dubble Data Ram is 1600MHz, but that is not the case in the third link it says 800MHz and 1066MHz. But the original ram inside the laptop has 1333mhz (2GB 1Rx8 PC3-10600S-9-10-B1 Micron, original ram).

You can see from those pictures what I mean

Could please someone tell me what the maximum and minimum clockspeed is and where you find this. Please....
