Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

ata - something to hookup hard drives (expensive)
Dimm - type of ram
Raid - is for hook up more hard drives in ide
scsi - is another way to hookup hard drive (mostly in servers)
isa - is a very old slot on old mobos (dont worry about this)
unbuffered - i dont really know...
non-ecc - is a type of ram for non servers
Dimm - type of ram

ATA - Advanced Technology Attachment - this is a standard used for hard drives and disk interfaces. Also termed IDE (like IDE cables).
DIMM - Dual inline memory module - a circuit that has memory chips. An example would be RAM.
RAID - Redundant array of independent disks - using two or more hard drives in conjunction for things like increased data transfer or data mirroring (when a drive stores the same data that's written to another drive; for example, you have two hard drives in RAID 1 (mirroring). One drive stores a file, and the other drive mirrors it and also stores that file at the same time).
SCSI - small computers systems interface - a connection interface generally used for input devices, like hard drives.
ISA - integrated systems architecture - an old standard for computer input/output devices. It's been replaced by PCI, which features a 32 bit interface, while ISA is only 16-bit.
Unbuffered memory - almost all memory in general use is unbuffered. Buffered memory has a chip on it which amplifies the clock signal across the entire RAM module and reduces the chance of memory errors with input/output data.
non-ECC - RAM that doesn't employ ECC means that it doesn't check the data to verify that it's correct. ECC RAM does.

ata: a format of data packets which are designed specifically for cdrom drive and hard drives. they communicate over a specific ATAPI/IDE wire pattern based on scsi protocols (this is hidden from the user in almost all operating systems - but fully present).
dimm: a common term for the format of most modern memory modules. a dimm of ram refers to a stick of memory, and a dimm slot is the slot on the motherboard which the stick of memory plugs into. like ata and scsi, there are multiple formats and technologies for this.
raid: i don't remember what it stands for, but basically it's a set of technologies to increase hard drives (plural) 1) security and/or reliability 2) speed/performance or 3) both. the more common modes: RAID 0. highest performance, worst method if data matters to you. what it does is take N drives and makes those N drives function as one. so you have N x capacity of the smallest drive for your total capacity, and the data gets split up between all the drives. so reading and writing is faster (2 to 10 million drives writing/reading for one file instead of one drive). if one drive dies, the entire array dies and is irrecoverable. if the power fails during a write, you got problems as well.
RAID 1: highest data backup, almost no performance increase over single drives. N/2 capacity. what this does is mirror one drive to the other so that should one drive fail, you still have a complete back up.
RAID 5: a more complicated storage method which requires 3 or more drives. you have n-1 drives working in a mode similar to RAID 0, with the last drive acting as an 'index' of what's stored. if any one drive fails, you can rebuild the entire file system from the remaining drives. a great compromise between performance and data recovery. storage capacity of n-1 times smallest drive capacity.
JBOD: no performance changes, no data improvements/harmings. it simply takes "just a bunch of drives" and stacks them together as one drive. (one hard drive just picks up where the last went off. so you have a 3GB, 6GB, 2GB, and a 15GB. put them in JBOD, and you have one 26GB drive)
isa: an outdated subsystem for communication to add-on cards and devices within the computer. PCI is the current more modern replacement to this, and PCI-X was the much superior version which never really left the workstation/server market segments.
This is not to be confused with pci-express, which is being designed to replace AGP, PCI, PCI-X, CNR, etc.
unbuffered ram and non-ecc ram are almost always used as the same thing, altho in correctly. ECC stands for error correcting code. it's unnecessary in desktops and most workstations, it simply slows stuff down. in critical environments, it's key. it does what it's name says. the buffered part of it has to do with the memory physically itself, i'm not really sure about anything more. registered = buffered, and allows for DIMMs of 8GB+ without corruption. unbuffered ram is generally faster with lower latency, but it usually starts to experience corruption commonly after dimm sizes exceed 1024MBs.
the bulk of the above is heavily summarized and probably 300% false, for all i know. search for some more indepth explainations would be the best bet

lol it isn't wrong, in fact it's probably better. simpler = better in a case like thisOriginally posted by KoZLop
oh well i tried
