anyone have got some OCZ Dual Channel Premier Series OCZ4001024PDC-K w/ Heatspreader (2x 512MB DDR400 Matched Pair, CAS 2.5-3-3-7) and know tis height?? cuz i need to be less than 40mm to fit under the thermalright Xp-120...........
 
The module's height is referred to as it's profile. Standard profile is about 30mm. But should be no more than 1.5 inch, or 35mm.

I would be surprised if the profile of this module were more than 35mm.

You can also try checking directly with OCZ.

Bah 2500rpm is pretty slow IMO.
Specially 120mm tend to make less noise even at the same speed

I am not that worried about ram height, I prefer ram depth! 😉

It's unusual for an ECC module to have a higher profile than its unbuffered counterpart, since the addition of an extra chip never adds to the height.

On the other hand, REGISTERED modules often require higher profiles because of the extra components and chips. Registered modules require 2 to 3 extra chips per bank.

Quote from the memory FAQs straight from the memory guru himself:

ECC Module: Stands for error-correcting code. An ECC module has an additional memory chip per memory bank that is responsible for detecting and correcting 1-bit data errors as data passes through the memory module.

Registered Module: A registered module contains an extra memory chip per memory bank that is responsible for holding data for one clock cycle. This process increases the reliability of data. Typically, registered modules are only used in data-sensitive or server stations where the focus is on the integrity of data.

ECC MODULES typically come with 9 (rare cases 5) chips per side. And are used in systems where data integrity is more important than performance. ECC modules are slower, but are normally compatible with desktop systems.

UNBUFFERED MODULES are common modules for performance systems including rigs designed for gaming. In these systems, performance is prefered over reliability. There is normally a gap in between the chips on the PCB for the ECC chip.

REGISTERED MODULES are normally only used in server systems.

For typical applications and games, UNBUFFERED is preferred. For workstations running specialized applications, ECC memory is a good choice. Server & unmanned network PCs, REGISTERED memory is the mainstaple.

buffered and registered are different.

A buffer is used to redrive or refresh data signals, so that there is no loss in performance of the data medium. A register actually holds data during the current and next clock cycle.

While data is held in a register, it can be read by other electronic components on the current and next clock cycle. This has many advantages including better error correction and control.

others I've seen puts the ECC chip at the buttom hence adds the height.

That's a REGISTERED module. A registered module is also ECC but not vice versa.

<b>EDIT:</b> A register also acts as a buffer. So a register is a buffer, but a buffer is not a register since a buffer doesn't necessarily hold (or register) data.

Brent you really know memory!
I'll ask Fredi if he can rename this forum to <b>Brent's memory forum</b>

BTW I really liked the memory document, I kept a copy while you finish it and make the sticky.

Be happy to explain further Wusy...
from a more technical perspective:

<b>WIRE</b> (unbuffered):
Data simply flows from A to B.

A ---------------- B


<b>BUFFERED OUTPUT</b>
The signal is refreshed as it goes from A to B. (signals lose integrity as they travel on a wire and through ICs over time) A buffer can be a small IC powered by a voltage (Vcc) input.

A ------ |IC|----- B
<A HREF="http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/ietron/buf.gif" target="_new">image</A>


REGISTERED OUTPUT
A register has the ability to store data for one clock cycle.

A ------ [REG IC]----- B
<A HREF="http://www.tpub.com/content/neets/14185/img/14185_134_1.jpg" target="_new">image</A>

The image shows the most basic unit in a register. Actually, the image is a device called a latch. A collection of two or more latches makes up a register.

The difficult concept with a register, that is not explained here, is how the data is held- but just know that it is held for one clock cycle. You'll notice from the image, that on the rising edge of the CLK, either a 1 or a 0 is stored in the register.

Why registered memory is useful:
1. Data is active for a longer period of time which helps maintain data integrity.
2. Data can be retrieved entirely on the next clock cycle.
3. Data transfers are improved by re-driving the signals.
4. With registered memory, motherboards can support higher memory sizes.
5. Greater reliability

hope this helps !

hmm memory have more than i think ther is (i got affected by a guide that says good memory is not needed unless you are water chilling a machine and OC it to the extreme, and any vaule ram is great for mild-medium OCing) and now that somoen pointed out that (very nicely as i was being an a$$ (why my '@" key isn;t workign here???) that i don't need a top notch cooler ATM cuz this is my first modern (non PII or PIII) rig that i'm gona OC so i sota freeed up some $$ on the ram department so i got some new rams to pick from) can someone tell me the height of

as that i do eventually plan to get better cooling and other components as time goes on (as i experiment with OC and maybe i even put a liquid chilled system on) so i would want to know the height of these ram and will they conflict with any cooler...

i'm very intrested in the OCZ el gold series one (217 CAD).. is it good? and can someoen explain the little number after CAS? i think they are trimmings but.... and i need to know how is good with these numbers 😛... (i was hoping to worry about them as i get my system and start OCing, but.... guess not) i think i can delay ordering for a few more days to know about trimming and all...

i might change my mind when i understand whhat are trimming and ram divider and all that...

OCing with older PC is easier... all ya need to is set a jumper and try to unlock the multiplier in the bios and if its locked then you can't do too much about it (slot 1 i'm talking about here)

😵 after reading the anandtech value ram round up the OCZ vaule VX performed better then some of the high end models???
ok where to get them? NCIX and anitec don;t carry them????
is <A HREF="http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1283677&Tab=2&NoMapp=0" target="_new">this</A> what the ram is? or i'm not even close as that the ones on the review have heatspreaders? (but hey i guess that they cut down more cost?)

edit what do ya mean wusy is it too crappy that you could eat em or too good you could eat em?<P ID="edit"><FONT SIZE=-1><EM>Edited by TheHolyLancer on 07/21/05 00:43 AM.</EM></FONT></P>
 
OCZ4001024WV3DC-K is the model number - google it.
