Can You Use Ddr3 Ram In Ddr4 Slots
Command and conquer first decade windows 10. No, the Mid-2012 MacBook Pro is in no way upgradable to DDR4 RAM. To use DDR4 RAM a lot of things must be compatible with DDR4 - one of those is the CPU itself. The Intel CPU in the mid-2012 MacBook Pro does not support DDR4 RAM. And no, DDR4 was not around in mid-2012. It was released to the market in 2014. Build Help cAN DDR4 slot also support DDR3? If I bought DDR3 memory, would I be able to put it into a DDR4 slot? Is DDR4 memory worth it? From my reading it doesn't seem to be a simple upgrade. You get more space and uses less voltage, but has a higher access time than DDR3?
Can You Use Ddr3 Ram In Ddr4 Slots
The computer is a Compaq Presario CQ40. It currently has 1 GB of RAM DDR2 (Samsung-manufactured). There are two slots in the RAM part.
It says 766 MB usable ( which I think is because part of it goes to being the graphics card). The processor is an AMD Sempron(tm) SI-42 2.10 GHz.
I wanted to upgrade the RAM to 2 GB with a new installation of one 1 GB RAM, but I was also wondering if I can replace the old 1 GB DDR2 with a new 2 GB DDR3 RAM, and add
one more 1 GB DDR3 RAM, making the whole RAM capacity to 4 GB DDR3.
Please give me some thoughts. I think there have to be compatibility between the
motherboard and the new planned DDR3 RAMs as well, which I am not sure how to check.
Thanks!
Another thing to note is that the pin placement is different between each iteration of DDR memory. Unless the motherboard supports both DDR2 and DDR3, upgrading to DDR3 will not work. Here is where you can get more information: http://www.hardwaresecrets.com/article/Everything-You-Need-To-Know-About-DDR-DDR2-and-DDR3-Memories/167/7. If the computer was a desktop, I would say unless you wish to upgrade the motherboard, stick with DDR2. The cost and effort it takes to just upgrade the motherboard so you can use DDR3 along with your existing processor and hard drive is not worth it, mostly since the performance gain may not be that big of a difference to really notice. Since this is a laptop, you would not be able to upgrade the motherboard, so you would be stuck with DDR2.
yep , Oron is right , DDR2 and DDR3 are different technologies and the motherboard may not be compatible with DDR3 RAM , So just consult it with your motherboard manufacturer.
You cannot change DDR2 modules for DDR3, they are different technologies and the modules are not compatible with each other.
According to Crucial you can upgrade your laptop either to 4GB or to 8GB, depending on the exact model. I suggest you head over to Crucial's site (crucial.com in the US, crucial.com/uk in hte UK, and I'm sure there are other local versions) and run the 'system scanner' which will identify your model accurately, and will take you to a page showing you all the upgrade options available (available from them, that is, but they have a fairly comprehensive stock of memory modules).
According to the manual
http://h10032.www1.hp.com/ctg/Manual/c01714937.pdf
1) 2 SODIMM slots
2) Supports up to 4 GB of system RAM
3) PC2-6400 800-MHz, DDR2
4) Supports the following configurations:
? 4096 MB total system memory (2048 × 2)
? 3072 MB total system memory (2048 + 1024)
? 2048 MB total system memory (2048 × 1)
? 2048 MB total system memory (1024 × 2)
? 1024 MB total system memory (1024 × 1)if you change to DDR3 you will have problems
I bought a new PC, and all the parts arrived today! Awesome!
Except the RAM. It hasn't even shipped yet and won't be here until Monday. :(
In the meantime, would it be possible/advisable to use my old DDR2 800 RAM (4GB) until my shiny new DDR3 shows up? Both are 240 pin, but I wasn't sure if DDR3 slots were backward compatible w/ DDR2. Sometimes they move the little slip on the stick around..
Here's the old RAM:
G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400PHU2-2GBHZ
And here's the new RAM:
Corsair XMS3 8GB (2x4GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMX8GX3M2A1600C9)
And in case it matters, here's the motherboard I got:
ASUS Micro ATX DDR3 2600 LGA 1150 Motherboards H97M-E/CSM
I'm formatting and moving over the SSD in my existing PC, so before doing all of that I wanted to make sure the old RAM would work too. Thanks for any help you guys can provide!
