Which memory to upgrade to?

hi fellas
i needed some expert advice for upgrading my system ram, as for most of applications e.g. mozilla, they use up a lot of ram and system starts using page files and hence the speed is greatly affected.
my laptop is hp pavillion dv1615ts
i currently have pc2700 DDR RAM - 512MB and i wish to upgrade to 1 GB

the essential system specs are:

Intel(R) Pentium(R) M processor 1.70GHz
Core Speed = 1697.6 MHz
Multiplier x FSB = 17.0 x 99.9 MHz
Rated Bus speed = 399.4 MHz

Northbridge Intel i915GMS/i910GML rev. 03
Southbridge Intel 82801FBM (ICH6-M) rev. 03
Memory Type DDR
Memory Size 512 MBytes
Channels Single
Memory Frequency 166.4 MHz (3:5)
CAS# latency (CL) 2.5
RAS# to CAS# delay (tRCD) 3
RAS# Precharge (tRP) 3
Cycle Time (tRAS) 7

Memory SPD:
DIMM # 1
SMBus address 0x51
Memory type DDR
Manufacturer (ID) Nanya Technology (7F7F7F0B00000000)

JEDEC #2 2.5-3-3-7-n.a. @ 166 MHz

DMI Processor
manufacturer Intel
model Intel(R) Pentium(R) M
clock speed 1700.0 MHz
FSB speed 400.0 MHz

total width 64 bits
data width 64 bits
size 512 MBytes

Also, i have heard that my motherboard also supports DDR2 RAM, but doesn't it have different connector? How will it fit in?
Since DDR2 RAMs are cheaper and faster i would like a DDR2 upgrade if possible.
Please suggest possible options.

More about which memory upgrade
  1. I could find nothing about the memory you want. I'm thinking your best bet may be to use Crucial's Memory Finder tool to see if your memory is available
    they have a tool there that can scan your system and figure it out.
    Either that or, Ebay...
  2. Well, you have a couple options. One, you can just add another 512MB module like this PNY 512MB 200-Pin DDR SO-DIMM DDR 333 (PC 2700) Laptop Memory Model MN0512SD1-333-V2

    Or two, you can take out the 512MB module that's in it currently and replace it with a 1GB module like this CORSAIR 1GB 200-Pin DDR SO-DIMM DDR 333 (PC 2700) Laptop Memory Model VS1GSDS333

    Honestly though, even if you maxed it out to the full 2GB that it supports, it's not really worth it and won't really help as much as you might think it will.
  3. thanks for the suggestions guys.
    i am aware that increasing the ram to 1 GB will improve speed related only to paging but not while loading of application for the first time.
    i was wondering if DDR2 option could improve the speed noticeably or so and is DDR2 option possible.
    I have tried various tools including crucial but could not find DDR2 compatibility though the chipset used in my laptop, i.e., intel 915GMS supports DDR2 according to intel
    please shed light on the last point
  4. Everything I read while researching this said normal DDR only for that model.
  5. hpolduser said:

    The chipset may support it, but that board in that model apparently doesn't. Nothing I found about that model says otherwise.

    In fact, everything that I can find says PC2700 only, which would mean DDR2 is definitely out of the question.
  6. thanks for clearing my doubts, i will be buying the 1GB DDR stick of PC2700 only
