Hello, well I have a laptop with only 3 GB ram and always lacking it since I'm running Ubuntu 10.04 Lucid (64bit OS). And my problems is that officially my Laptop is supposed to support only up to 4 GB RAM, this means 2 x 2 GB memory modules with 800 Mhz clock frequency. The current setup is 2 GB + 1 GB Modules with 667 Mhz frequency. So the questions are what would happen if I tried putting in instead of that 1 GB module a 4 GB module with for example 667 Mhz (The module would be of the same type, but just size not 2 GB but 4 GB). What could happen? Would the module not get recognized by my System/Chipset at all? Or would the System see the new module only as 2 GB large instead of 4 GB? Or is it possible that the System would successfully accept the new 4 GB Module and I would have 6 GB RAM in my System? Please help me guys with this. The manufacturer says that it's recommeded to use Maximum 2 x 2 GB memory modules with 800 Mhz to ensure the system is stable, and they don't guarantee any functionality for any different configurations. Also whatever Module I choose, schould I go for the RAM with higher frequency or the frequency so that both of my modules have the same frequency? Cause right now my modules are 667 Mhz, so the new module should be also 667 Mhz or should I aim for the highest frequency? Thanks in advance. Arturas
Well can somebody at least tell me what's better to use? All RAM modules in the system of the same frequency or using different speeds is ok? What's more stable and more fast????
I have a Samsung NP-R510-AS01EE Laptop. The practical thing is that From Samsung support they said it supports max 2 x 2 GB Details about the memory: *-firmware description: BIOS vendor: Phoenix Technologies Ltd. physical id: 0 version: 07LI.MP00.20080926.SCY (09/26/2008) size: 108KiB capacity: 1984KiB capabilities: isa pci pcmcia pnp upgrade shadowing escd cdboot acpi usb agp smartbattery biosbootspecification *-cache:0 description: L1 cache physical id: 5 slot: L1 Cache size: 64KiB capacity: 64KiB capabilities: asynchronous internal write-back *-cache:1 description: L2 cache physical id: 6 slot: L2 Cache size: 3MiB capacity: 4MiB capabilities: burst internal write-back *-memory description: System Memory physical id: e slot: System board or motherboard size: 3GiB *-bank:0 description: SODIMM DDR2 Synchronous 667 MHz (1.5 ns) product: SODIMM000 vendor: Mfg 0 physical id: 0 serial: 1234-B0 slot: M1 size: 1GiB width: 64 bits clock: 667MHz (1.5ns) *-bank:1 description: SODIMM DDR2 Synchronous 667 MHz (1.5 ns) product: SODIMM001 vendor: Mfg 1 physical id: 1 serial: 1234-B1 slot: M2 size: 2GiB width: 64 bits clock: 667MHz (1.5ns)
Well yeah in my case I can put that in. But so OK, what I'm planning to do, right now the current RAM configuration is 2 GB + 1 GB, all 667 Mhz clock rate. So I'm thinking of buying an new 2 GB module instead of that 1 GB module and switching it. Now the question is what clock rate should I buy the new module? Is it better to use 800 Mhz or 667, so that both Modules in the System would have the same clock rate? I'm not planning to switch both modules just for the frequency...
If your 2 gig of ram is already @ 667 mhz then you will need another one the same.. You cannot miss /Match them..You will have to buy either 1-2gig 667 chip or 2-2 gig @ 800 mhz..
