HP 8770W max RAM speed

[martin778]

Hi all,

Does anybody know if the 8770W take 1866MHz DDR3L RAM like the G.Skill 1866MHZ CL10 Ripjaws?

It has a 3840QM but planning to install a 3940XM and install 4x8GB 1866CL10's.

You’ll be fine. I think that @MiRaGe was running the same modules, or something like that.

No, mines were Kingstons with Kingstons chips at 1600@1866 CL9

Interesting, so they are overclockable in the 8770W or did you re-program the SPD?

 

At this moment the Ripjaws 1600C9 or 1866C10's seem to be the only ones available.

 

P.s

On a side note - has HP ever patched the BIOS on these machines disabling undervolting/ThrottleStop?

I know for sure they did that with 8th gen onwards.

I did modify their SPD with Thaiphoon Burner

Max native speed is 2133mhz DDR3 Kingstone HyperX Impact. HP Bios is encrypted and locked, undervolt is not possible on this generation.

Ok, so it kinda overrides Intel CPU spec. I installed 1866 C11's today and they work absolutely fine.

Wonder if there were any modded BIOSes for these? Would be nice to push these 1866's from 1.35V to 1.5V and see if they'd do 2133.

i have 1866mhz DDR3L's in my 8570W, CPU-Z shows as 1600mhz in Mempage, but in SPD page they are 899x2 so 1800.  Not sure if they can be OC'd would love to know as i still havent found a set of 2133's yet,  they are proving to be tooo elusive.
