Memory or DRAM is the "working" memory of the computer. It's used to store data for programs (sequences of instructions) on a temporary basis.
Storage drives -- hard drives and solid state drives -- are the permanent memory for the programs and documents on your computer.
Data transfer rate is the rate at which data can be sent or received. This is determined by your motherboard. A drive with a higher transfer rate will only run at the rate of the motherboard's transfer rate.
Cache is a type of working memory that allows the drive to perform faster.
RPM is the rotations per minute of a hard drive which effects the speed of data transfer.
Solid state drives are non-moving memory, so access speed is instant.
I purchased CT51264BF160BJ new from Amazon few months ago which seemed to have normal package/sticker and runs okay.
However, MemTest86 identifies it as Super Talent CT51264BF160BJ.M8F in the PC (JEDEC SPD 1.0).
Does this make sense - was there some temporary issue in manufacturing week 7 of 2014 where Crucial programmed Super Talent's info (module rev x4444, mfg loc 5)?
My more recent purchase of CT51264BF160BJ from NewEgg shows SPD 1.1 with reasonable Crucial info.
Both SODIMMs have the same number of micron chips but the recent chips are slightly smaller.
The memory I need has been out of stock for a really long time. Is there anything else that will work? Is there any way to cross reference Crucial kit part numbers (often available online at newegg.com or amazon.com) to be sure they are compatible before purchasing?
Thanks for your message.
I have looked in to the ASRock 775Dual-VSTA system and we recommend that the maximum memory it can take is 2GB in total. That's 2x1GB modules.
You said that you currently have 3GB of memory installed. Sometimes you can go above the manufacturers recommendation but there is no guarantee that your system would work with 4GB installed.
I would be more than happy to recommend a single 2GB module for you. What I would need first would be some details about your existing 2GB module. This is so I can match it as much as possible when recommending memory.
On the existing memory module there will be a sticker that gives you details about the speed of the memory module. It will say something like "PC2-6400". Can you confirm what it says?
Once I have that information I can look at recommending memory that matches the speed of your existing memory. However, as we don't advise this system can support 4GB I cannot guarantee that it will work. All our memory does come with a lifetime warranty and also a 45 day return period.
If you do have any other questions at all, please don't hesitate to ask.
Thank you for contacting us today. I pulled up the link to the available upgrades and it appears that the real difference between the parts is the speed.
This part is basic Crucial PC3-12800 RAM. It's going to be the slower upgrade for your system, but would still be a great upgrade for your system.
This memory is basic Crucial PC3-14900 RAM. This is going to be the fastest upgrade for your system.
This part is Ballistix Sport. It has the same speed as the Crucial PC3-12800 RAM, but has an added heat spreader. Our Ballistix line is made for those are heavy computer users, gamers, graphic designers, etc.
This is the Ballistix Sport version of PC3-14900 RAM.
Please let us know if you have any other questions about these different types of RAM. Hopefully this helps clear up the differences
