hp HDX18 RAM upgrade to 8GB FAIL - also what SSD can I use?

I tried to upgrade my HDX18 - 1390eb from 2x 2GB to 2x 4GB RAM
but, it doesn't work

this is what I put in:
2x
Corsair CM3X4GSD1066 PC3-8500 4GB 7-7-7-20 204pin SODIMM


this is what was in the laptop original:

2x
Samsung 2GB SODIMM 1067Mhz 80ce (PC 3 8500)

Code:

# Processor
# Front side bus / HyperTransport 1066 MHz
# processorcache:6 MB
# Processor model:Intel Core 2 Quad Q9000
# Processor-clockspeed:2.000 MHz
# Processor:Intel Core 2 Quad

running on: Windows 7 ultimate x64

what could be the problem?

I tried running it on 1 x 4GB , this worked.
I tried 1x 4GB and 1x 2GB , this didn't work
I allready tried taking out the battery and holding the on/off button 30sec. No succes.

The computer doesn't boot up at all when i put in the 8GB, black screen. but i can hear then fan blowing an the laptop makes start-up noises.

 

Failed because you used the wrong type of RAM. PC2-6400 is the type you need. Hopefully you didn't kill the controller.

See the service manual: http://www.scribd.com/doc/19192044/HP-HDX-18-1180CA-Service-Manual

 

ok, thx for fast reply!
so, this one should work.

Corsair PC2-6400 Modules
VS4GBKIT800D2 PC2-6400 4GB Kit 5-5-5-18 240pin DIMM

just to be sure to get it right this time.


EDIT, the laptop is still working with the 2x 2GB without a problem, so i hope nothing is broken, or wouldn't i notice it at first?

EDIT 2 : PC2-6400, 800-MHz, DDR2 , is this much faster then 2x 2GB DDR3?

 

Wrong type of RAM, wrong size. A 4GB kit is (2) 2GB sticks.

And it has to be 200 pin PC2-6400 DDR2 800 mhz RAM.

Like this: Newegg.com - CORSAIR 8GB (2 x 4GB) 200-Pin DDR2 SO-DIMM DDR2 800 (PC2 6400) Laptop Memory Model VS8GSDSKIT800D2

 

ok, thx allot
Is it going to improve allot over the 4GB DDR3?

 

8GB RAM won't improve things unless you are maxing 4GB out. If you want a real kick in the pants, get an SSD. It will improve things quite a bit as far as the OS operations and read/write operations. Even boot time will be markedly improved.

 

i didn't know this was possible for a HDX18?
so i can upgrade this laptop with SSD?
if so, which model do you recommend?

 

Is it possible to upgrade a HP HDX 18 1390eb with a SSD?
if so which models work / are advised?

 

Basically any 2.5" SATA SSD such as OCZ's Vertex and Vertex 2 series or Intel X25-M G2 series. There's others that are cheaper. But these are the favorites around here.

Also see this thread for loads of info about the HDX 18: http://forum.notebookreview.com/hp-envy-hdx/300221-official-hp-hdx18-owners-lounge.html

 

Yeah, i started reading that thread, but 500+ pages is overkill thx for the info, i'm going to invest in a SSD then i guess, better performance for the money!

 

Yep. Best way to go.

Happy Holidays.
