Unbuffered output has nothing to do with ensuring your data reaches the disk; that functionality is provided by flush(), and works on both buffered and unbuffered streams. Unbuffered IO writes don't guarantee the data has reached the physical disk -- the OS file system is free to hold on to a copy of your data indefinitely, never writing it to
Jul 20, 2008 · about ecc: non ecc memory will be about 2% faster than the same ecc memory, so it's almost negligible, and it's not THAT uncommon or THAT unneccesary, almost all dells use ecc memory, part of the reason they have a reputation for being reliable (also because since ecc is slightly more expensive, the fact that dell does not cut corners in making their machines is evident) also, a machine is Jul 03, 2014 · All registered and fully buffered memory modules also include ECC functionality. But there is also ECC unbuffered memory that is usually used in higher end workstation computers. In some cases, you can use ECC unbuffered memory in a computer that takes unbuffered memory but does not have ECC functionality. It just will not use this feature of Directly connected, unbuffered RAM vs. buffered/registered RAM isn't a case where one is better or worse than the other. They just have different trade-offs in terms of how many memory slots you can have. Registered RAM allows more RAM at the cost of some speed (and possibly expense). I've seen several different types of ram. There's the standard memory at best buy, ECC unbuffered, ECC buffered, and ECC registered (same thing?) Which of these are compatible? Can I put ECC memory in a non-ECC board? Can I put nECC memory in an ECC board? Can buffered and unbuffered both be ECC RAM will only work in motherboards that support it. The E and U at the end of the names indicate the ECC and Unbuffered status Insert mode . The question was about 5300P, not 5300U memory. I'm looking to add more RAM to my laptop for gaming, video editing, and engineering software (CAD, Programming, etc). I currently have a dell G7: i7, 8gb RAM, 1060 6gb max-q. My laptop has 2 RAM slots. i know my RAM is 2666MHz and that it came with 2x4GB sticks, but it doesnt say if they're buffered or unbuffered sticks. Ive just been studying about all the forms of SDRAM etc, and when it came to buffered/registered DRAM I found out that normal PC's usually have upto 4 slots for SDRAM, any more gives producers of

For unbuffered (non-registered DIMMs), the KT266 (as well as the Apollo Pro266 chipset) offers the option to reduce the command latency to 1 cycle, meaning that the command is latched on the next Buffered vs unbuffered is not an issue with teh 2013 Mac Pro since you can't the one in that regard. Registered vs unregistered is an issue. In any event make sure yo get the memory from a place that says thay will work in a 2013 Pro. What I conclude is that you can mix 8 and 4 GB sticks but not 4 and 16 and not 8 and 16 .
For unbuffered (non-registered DIMMs), the KT266 (as well as the Apollo Pro266 chipset) offers the option to reduce the command latency to 1 cycle, meaning that the command is latched on the next
It's rare (these days) that a board would support both buffered (registered) and unbuffered. So get a board that supports the amount of RAM you need, then get memory that matches what the board requires. (BTW, "fully buffered" memory is different entirely than "buffered"/"registered". FB-DIMMs are a technology Intel had in it's servers.) Sep 12, 2009 · Also, some memory also is classified as ECC RAM, which has additional circuitry to determine if data has errors and correct them if so. It's also more expensive, and intended for reliability, and it's usually a paired feature with buffered/registered memory. Nov 05, 2013 · To see if ECC RAM really is more reliable, we looked up our failure rates for ECC and non-ECC RAM over the past 3 years. One thing to note is that while we have tried many different brands of memory over the years, we have always returned to Kingston due to their consistently lower failure rates - up to 6x better in some cases! Fully Buffered DIMM (or FB-DIMM) is a memory technology that can be used to increase reliability and density of memory systems.Conventionally, data lines from the memory controller have to be connected to data lines in every DRAM module, i.e. via multidrop buses. Buffered/Registered: Unbuffered; Features: CT2K51264BD160B is an 8GB kit consisting of (2) 4GB DDR3L Desktop modules that operates at speeds up to 1600 MT/s and has a CL11 latency. It is Unbuffered and is non-ECC. It conforms to the industry standard UDIMM layout of 240 pins and is compatible with computers that take DDR3L UDIMM memory. UNBUFFERED - No buffer the memory is connected directly to the chipset controller, DDR, DDR2 and DDR3 modules that are used in desktops or notebooks are mostly unbuffered. BUFFERED - A buffer is used to help the system control large amount of memory. Used to describe older technology modules such as EDO and SDRAM.
