HI . the 8 gb 2666 ram is delivered to me and then i came to know its dual rank and not single rank as my default skhynix.
CT8G4SFS8266 crucial SINGLE RANK
CT8G4SFRA266 DUAL RANK crucial is delivered
Hynix HMA81GS6CJR8N-VK preinstalled
i had already shared amazon links of all before ordering to u .
but u dint inform me about the ranks and to get the single rank one which i was unaware of.
I understand that my current RAM is a single-rank RAM and my new one is dual-ranked RAM and is compatible as per crucial
but not recommended.. will it work in dual channel mode in full performance ..
or shall i return it but it seems amazon has only replacement policy.
i mailed crucial about it and they too recommended single rank one.
let me know what would be best to do now.

Thank you again for the prompt response..
Yes i agree it will work as dual channel too but
I guess with overall 5-10% reduced performance..
I called hp now and they confirmed the same..
They asked me if i can return the product they can try giving me the same part too..
Also i emailed crucial about it and they replied that as best practises we must use same type, though different type is compatible.
Their crucial scanner always recommends all the ram's that are compatible but never gives which is best compatible and its just like marketing gimmick. They are even recommending via crucial scanner 3200.mhz version in 1st list to just get sales number and not the best compatibility i believe..
Can you actually explain the real difference between single vs dual rank as i am not very clear about its working principle..

This article should explain the difference.
3200 MHz memory would just run at 2400 MHz just like the 2666 MHz memory will.
The only reason to buy 3200 MHz memory would be if you planned to install it in a newer PC that could actually run the memory at 3200 MHz.

i see that the 1tb hdd installed heats a lot and makes right side of touchpad warm,
room temp- 25 c
cpu temp- 37 c approx .. few tabs open
hdd 1tb seagate - 38 to 46 often(no r/w). idles at 38 c..
in my other laptops with hitachi/toshiba/wd idle hdd is 31c
read write temp is 34-35..
so techically this seagate runs hotter and makes palm rest hot.
how to fix it..
i see a driver at hp site.for same model hdd.
will this fix or need to ask hp for replacement.
never seen such laptop hdd hot at room temp 25c.
now just 1 tab open and its 40c.
sharing a temp profile of last month and current date where we see ..cpu temp less than hdd which is bad.

Unfortunately, I don't know if the firmware update is going to do anything to reduce the temperature.
The release notes for the update state this...- Provides improved hard disk driver (HDD) reliability.
I don't work for or represent HP, so I would not be able to advise you on how to get the drive replaced under warranty.
