install new ram different voltage

[fidows]

i want to upgrade my ram.but i don't know if it can because it has different voltage. 

this is the ram that i want to put in my notebook.

 

and this ram i have now in my notebook.

will anything will be affected if i mix different voltage ram? and also will it be dual channel if i add it?

Unless you can change the voltage within the BIOS it would not be the best idea. Chances are a 1.5v kit running at 1.35v is going to have an extremely hard time running at rated specs.

What is your exact model of Notebook? Vendors usually maintain a QVL, or at the very least RAM manufacturers will list compatible products if it is SODIMM marketed for notebooks.

Are you sure the RAM is not soldered in? I can't find it on Crucial's compatibility finder, and theirs is really the best out there. Closest matching was the Pav. 15-n276sa and Pav. 15-n278ea, both of which could be swapped to 16GB 1.35v kits. http://www.crucial.com/usa/en/compatible-upgrade-for/HP-Compaq/pavilion-15-n278ea

 

From the available options I would say a 1.5v kit is almost certainly out of the question unless you were going to run it at JEDEC 1333, or if the BIOS supports timing, speed, and voltage adjustment.

No. The model numbers are different.

 

Top DIMM: https://www.skhynix.com/products/computing/view.jsp?info.ramKind=20&info.serialNo=HMT351S6CFR8C

 

Bottom DIMM: https://www.skhynix.com/products/computing/view.jsp?info.ramKind=20&info.serialNo=HMT351S6CFR8A

From the spec page for CFR8A (bottom picture) - "Backward Compatible with 1.5V DDR3 Memory module" Meaning it could work if the top picture is your original kit that you found in your notebook. Judging from the top picture being a stock photo I'll go out on a limb and guess that the bottom picture is your particular DIMM.

^ That is your exact RAM, low voltage 1.35v, PC-12800, cl 11.

 

*edit* Cheaper option on ebay if you're in the US http://www.ebay.com/itm/HMT351S6CFR8A-PB-GENUINE-HYNIX-LAPTOP-MEMORY-4GB-DDR3-PC3L-12800S-/271711817006?pt=LH_DefaultDomain_0&hash=item3f43494d2e

Right, so you'll want the HMT351S6CFR8A not C. The C is a 1.5v kit, the A is a 1.35v kit that can work with the 1.5v C kits. Your laptop was designed to work with low voltage 1.35v kits, unless you can change the voltage within the BIOS only 1.35v kits should be used.

so if i want to use the 1.5v kit i should setting the bios?
