*HP EliteBook 8760w Owners Lounge*

By any chance - do you also use DC display with this 980M ??

 

Nope it is not my friend. I work on 1600 MHz for couple years on my 8760w.

 

You have to find a right model in order to work in dual mode (mine 2x 8GB). Also CPU need to support the 1600MHz.

 

You have RAM, capable of operating at 1600Mhz , but practically operating at 1333
Just take a screenshot of cpu-z and post it here to prove your theory.
No single 8760W/8560W in the world can operate at 1600Mhz for the memory. First Elitebook, supporting 1600MHz is 8770W.
Every i7 2nd gen support 1600Mhz, but the MoBo of 8760W doesn’t- it is locked by HP at bios level to operate at 667/1333Mhz
It has nothing to do with the channels - dual or single. Here we talk about the frequency of the memory modules.

 

Just got an 8760w so I've joined the club. What a fantastic chunk of laptop.

 

I can't access my screen right now but by far I remember not every 2gen i7 supports 1600MHz - just compare i7 2620qm with 2820qm.

Thus my worry about the HP lock u mentioned is unrecognized. Can u share the information about this lock anywhere www ?

 

I know what Intel i7 2nd gen support.
We are discussing here the support of HP mobo of 8760W with 2nd gen Intel i7 - every single i7, no matter it can provide 1600Mhz support for the RAM, is locked on bios level to operate at 1333. I had 2630QM, 2670QM,2920XM and 2960XM - every single one of them operated at 1333Mhz. Period.
You can take a look at the specs of 8760W on their site, it was mentioned there.

 

That is interesting but experimental nature drives me to dig deeper.
You claim it is mainboard dependent lockdown to 1333MHz.
How about different mobo variants just for 8760w ?? Not sure how many there really are - Ive heard about 2:
HP 652508-001 and 652509-001

What do you think - would that make a change in work @1600MHz ??

OR finally...would Bios update unlock the clock ??

 

To both your questions, the answer is no, unfortunately.
The two part numbers of the mobos indicate only that one is i7 capable (with 4 slots for the ram memory) while the other is limited to i5 support (2 slots for memory, 16GB max supported). Both have the same other specs including 1333Mhz ram frequency limitation.
As long as we speak about the bios, there is no official update from HP (I’ve tried all of them, including the latest F.66) which enables support of 1600Mhz on 8760W. When it comes to some modded unlocked bios - it never was, is or will be possible on workstation’s HP class laptops as long as they have protection and are heavily locked.
So, the only solution in this case (and my advice) is - move to 8770W. It is not a difficult upgrade, you need several parts and around 200$ if you get lucky to find the parts second hand at reasonable price on ebay.

 

I claim your solution to upgrade to 8770w is the best move for 1600MHz.
You mentioned something regard F.66 bios - I see its release outstands the others for a couple years. There is not much in the bios version history for details.
Do you or anyone know - what is new in this version ?? Is is worth of upgrade ?? Is there a way to rollback to the F.62 after upgrading to F.66 ??

Much preciate.
