Tech Question for Mobo
show user profile  donvella
I have a GA-P55-USB3 motherboard. I want to put in some more ram but am worried after reading the tech specs on this site

4 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory (Note 1)

Does this mean I cant put in 32gb ram? or is that 16gb per ram slot?

I also want to put a Seagate SATA3 3TB 7200RPM Barracuda 64mb in, it should support this im guessing.

That IS quite poorly worded on the info site..
I am pretty sure that they mean 16GB in all though.
Also the list of supported memory, does not list anything larger than a 4GB module..

Did a little reading up on the chipset though, and some mainboards with that chipset supposedly support up to 32GB.
And a single guy claims that he is running 48GB on his, even though the mainboard manual said max 24GB..

Regarding the disk. The mobo only has SATA2 ports.. But it should support a SATA3 disk, but it will only run at SATA2 speeds.. which is theoretically still 3GB/s.. which neither a standard SATA2 or SATA3 disk will ever reach..

Terribly boring signature.

3 things that limit maximum memory:
1) [mem slot count] * [biggest currently commercially available dimm unit] : a common example of this are many older 2 slot 1155 based motherboards. Since at the time of their release the biggest slab was 4gb they often state their max memory as 8gb, even though many have successfully put 16gb on them.

2) memory controller: on 1156 the mem controller was already integrated on the cpu so in your case it depends which chip you got, clarkdale and lynnfield are 16gb while bloomfield and gulftown are 24gb. I can imagine a mobo maker stating the lower of the two to avoid customer disappointment.

3) motherboard: sometimes motherboard makers deliberately cut some tracks from the dimm slots to save on costs, limiting the amount of memory that can be installed. Rather rare these days but it does happen, the problem here is that mobo makers never explicitly state whether or not they have done it so the only way to find out is for somebody to try.

>>is theoretically still 3GB/s.. which neither a standard SATA2 or SATA3 disk will ever reach..
its 3Gb/s, important distinction since thats 384MB/s which many SSD's reach with ease

Heh, Brainfart on my behalf there.. yeah 3Gb it is..
I only have one SSD in my system, the rest are regular SATA3 7200RPM storage disks.. I think the max copy speed I have seen is about 120MB/s.. Which is pretty good, but certainly no stress on the SATA controller.

Terribly boring signature.

ended up just getting the 16gb ddr3 1333mhz, works well. That will teach me for not investing in a decent mobo. I will hold off on the hdd for now but yes im sure it supports sata3 - more interested in 6gb/sec HDDs (as storage) but again my max speed transfer is usually 80mb sec (pretty crap IMO) but whatev. Thanks for the help
