Xtreme terminology

[D_o_S]

Hi guys and gals!

We've started this thread because of a request here: http://www.xtremesystems.org/forums/showthread.php?t=52690

This thread is going to be about all those computer related words that we often use, but some members do not understand what they are. Whenever you notice a word in someone's post that is at least a little bit computer related, and you don't understand what it means, there's a good chance you'll find it here.

So, everyone, please PM me / post your suggestions.

To start it off, here are some from the Xtreme mods section:

General :

PCB= Acronym of Printed Circuit Board
VR= Variable resistor
Vsense= PSU line that sense the voltage that the rail draws
IC= Integrated circuit
Cap= capacitor
SMD= Acronym of Surface Mounted Device, same as SMT
SMT= Acronym of Surface Mounted Technology, same as SMD
Traces= Lines printed on PCB that transmits electrical signals
V= Voltage in any form ex: VDimm meens Dimm Voltage
FET= Acronym of Field Effect Transistor
MOSFET= Acronym of Metal Oxide Semiconductor Field Effect Transitor
CERMET= Acronym of CERamic METal
PWM= Power Management IC
Electrolytic= A fixed capacitor consisting of two electrodes separate by an electrolyte
Vdroop= The difference between the set outlet pressure at a flow rate of zero and the outlet pressure at a given flow rate. Meens difference between BIOS setting and IC control.
PSU= Acronym of Power Supply Unit *Not an actually Vmod related part, but is subject to be Vmodded*

Motherboard :

Vcore= CPU voltage
VDimm= Memory voltage
Vmem= Same as Vdimm
VDD= Chipset voltage
VAGP= AGP voltage **Not helping Video Card core and mem overclock**
VTT= 1/2 of vDimm (referred to as vbt on NF7)

Video Card :

VGPU= GPU voltage
Vmem= memory voltage
Vref= Reference voltage
VDDQ= 1/2 of mem voltage. Same as VTT/Vbt

Vsense= PSU line that sense the voltage that the rail draws

not only, its also the sense line on ics used to sense the voltage they are supposed to control ans stabilize :)

pot / trimm pot = vr

nice post. some usefull info in there.

Magic smoke? :D
All the fluffy stuff flies up but it doesnt all fit back in :eek:

Good initiative. :toast: This will certainly help many members

Alright, some memory related words here (thanks to moddolicious)

CAS Latency
The CAS latency is the delay, in clock cycles, between sending a READ command and the moment the first pice of data is available on the outputs.

tWR - Write Recovery Time:
tWR is the number of clock cycles taken between writing data and issuing the precharge command. tWR is necessary to guarantee that all data in the write buffer can be safely written to the memory core.

tRAS - Row Active Time:
tRAS is the number of clock cycles taken between a bank active command and issuing the precharge command.

tRC - Row Cycle Time:
The minimum time interval between successive ACTIVE commands to the same bank is defined by tRC.
tRC = tRAS + tRP

tRCD - Row Address to Column Address Delay:
tRCD is the number of clock cycles taken between the issuing of the active command and the read/write command. In this time the internal row signal settles enough for the charge sensor to amplify it.

tRP - Row Precharge Time:
tRP is the number of clock cycles taken between the issuing of the precharge command and the active command. In this time the sense amps charge and the bank is activated.

tRRD - Row Active to Row Active Delay:
The minimum time interval between successive ACTIVE commands to the different banks is defined by tRRD.

tCCD - Column Address to Column Address Delay

tRD - Active to Read Delay ?:

tWTR - Internal Write to Read Command Delay:
tWTR is the delay that has to be inserted after sending the last data from a write operation to the memory and issuing a read command.

tRDA - Read Delay Adjust
(got it from here http://www.techpowerup.com/articles/overclocking/64)

update (little more info)

Max Asynce lantency= 00.0-15.0 in 1.0 incements.
I would suggest trying 5.0-10.0 depending on your ram. 5ns will problobly not allow much overclocking, and 7-8ns is usually the optimal

Read Preamble time= 02.0-09.5 nano sec, in 0.5 increments.

I would suggest 4.0-7.0 depending on ram. 4ns will probobly not allow for much overclocking, and 5-6ns is usually the optimal

Thanks for keeping this going DoS :up:

We'll have a better place for this thread soon.

[antipop]

PoS = not good when talking about some hardware like "this mobo is a PoS"

ok maybe that was a bad example but i can't think of anything right now

ps why is it in the wampeteer section?

edit maybe add some cooling terms like WC rad T line HSF ...

Thread has its home now! Special thanks to all future contributors from the purveyor of xtreme news . . . ;)

[skate2snow]

Sorry, but I may have missed something.... Why did you copy my previous thread?

[CaTalyst.X]

Yeah im kinda wondering this myself.......skate made the original big thread at EOCF and a couple of us added some stuff....then he posted it here and this is pretty much a blatent copy.......
