Cheap memory

I am looking to buy 2 x 2GB of ddr2 memory.

ccl computers are selling this - CCL Choice 4GB (2x 2GB) 800MHz DDR2 RAM -
which at £18.91 is half the price of the rest.
Is this memory any good?
What is going on here?

what do you mean by "any good"? Please define what is "good" for you.


What is going on here?

They are running a business. They are selling you stuff which you can
buy or not buy. Is this OK with you?






This is not an invalid reply.

You mean like this ?

https://www.cclonline.com/product/24...-Kit/BUN0117/#

* Voltage: 2.048V
* Latency Timing: CL6
* Module Name: PC2-6400
* 2 X 2GB Dual Channel
* non-ECC Unbuffered Memory

Isn't DDR2 nominal voltage 1.8V ? I forget :-)

So they're selling you bog standard (slow) CAS6 latency
RAM, and it needs 2.0V to run instead of the usual 1.8V ?
I think I can do better than that.

Sometimes, RAM is half price, when it is high density, single
rank, using (16) x4 (nibble wide) memories. Which works on AMD,
but Intel spec sheets "do not approve". The trouble with the
word "High Density" is marketing morons use it for more
than one purpose, and then it isn't reserved for my
disparagement purposes :-) Where I need to disparage
something you should not buy.

Because the CCLonline RAM, doesn't have a real datasheet,
I could only identify nibble-wide memory, if someone dumps
an SPD table, or someone in a forum discovers it isn't working
right in their Intel chipset board.

When the RAM failed on the machine I am typing on,
I bought this. Only I buy them in Canadian dollars.

Corsair TWIN2X4096-6400C5 (2x2GB) £109.99 GBP

http://www.corsair.com/en-gb/twin2x4096-6400c5

SPD Latency 5-5-5-18 CAS5 is low latency (doesn't really matter)
SPD Speed 800MHz
SPD Voltage 1.8V --- works in mobo without Vdimm adjustment
Speed Rating PC2-6400

My machine has had maybe three or four loads of RAM
in it (no, they didn't all fail), and you really can't
tell the difference between CAS6 and CAS5. The CAS5 is
slightly better (theoretically).

If the above RAM really is needing 2.0V to meet
the speed and timing, then make sure your motherboard
Vdimm can be adjusted to that level. Look in the BIOS
and see if there is a section for custom RAM adjustments.
The 2.0V value isn't overly high, so won't fry anything.
They're not "going crazy" with the voltage here. But you
still need a VDimm adjustment in the BIOS to get there.
Since these RAMs don't have an XMP profile, the BIOS
cannot be automatically commanded to go to 2.0V. Newer
RAM types, in some situations the settings are (almost)
totally automated. And it bumps itself up to the
right voltage.

*******

Now, when I look at CCLOnline, look at the bargain they have.
This is very similar to what I bought.

VS4GBKIT800D2 (2x2GB) £39.98 inc VAT

http://www.corsair.com/en-gb/vs4gbkit800d2

https://www.cclonline.com/product/36...y-Kit/RAM5954/

SPD Latency 5-5-5-18 CAS5 is low latency (doesn't really matter)
SPD Speed 800MHz
SPD Voltage 1.8V --- works in mobo without Vdimm adjustment
Speed Rating PC2-6400

The only difference, is a slight difference in heat
spreader. (Again, doesn't matter. In fact, a "fat"
heat spreader, tends to choke off airflow and is
counter-productive.)

RAM like that should work in any board. It might even
work with an NVidia Northbridge :-) Those are picky about RAM.

And because that one is rated for 1.8V, that would even run
in a server mobo that lacks VDimm adjustments. Or, in a Dell.

Since Corsair is "branded RAM", Corsair will not sell you
DIMMs with nibble-wide chips. But a guy on Ebay might do it.
Let's see if we can spot an "honest" Ebay person trying
to sell rubbish... This only took me 20 seconds to spot.
Yes, these dudes are honest.

"Buyer Note: it is hgih density, Only fit for AMD Motherboard.
It can't support any intel motherboard, "

High Density 4GB 2x2GB PC2-6400 DDR2 Approximately £8.71

OK, so that establishes that the CCLOnline, at £18.91 inc VAT,
isn't as cheap as actual nibble-wide (ugh) DIMMs. So the CCLOnline
product you've selected, might very well use x8 wide
chips (the "right" width).

So let's review the choices:

Ebay - Approximately £8.71 Do not buy under any circumstances.
High density/nibble wide, as stated.
I'm trying to stamp this stuff out :-)
AMD users try to sell this to Intel users,
and all hell breaks loose. Not everyone
admits they're nibble-wide and verboten.

cclonline CAS6 2.0V £18.91 Likely x8 chips (based on price).
Check your BIOS! VDimm adjustment!!

VS4GBKIT800D2 CAS5 1.8V £39.98 Works anywhere. Value Select.

TWIN2X4096-6400C5 CAS5 1.8V £109.99 Oops! I got taken! :-) Hahaha.
But this is what they had at my
primary computer store here.
That's my excuse.
HTH,

Thanks Paul, that explains it very clearly so that even i can understand it.
