Brought these today for £99 ****This week only****along with a E8500.

I have the memory running now at 1750Mhz 1.9v

The cpu not bad either 4.2Ghz so far.anyways my results below for the memory...

1.9V (which is ok as long as you have a fan above them for 24/7)

Very good kit for the price and great for anybody think about upgrading to DDR3...
 
cheers mate, benchmarks are much appreciated! bought some of this ram 2 weeks ago for my new build and am yet to use it due to the trickle of pennryns emmiting from intels backside....

i blame mcdonalds. :p
 
Very little IMO, thats why Intels are Quad Pumped and your FSB of 1333 only really need Memory at 667.

It would score you higher in some benches and some APP's may benefit a tad.

A quad pumped FSB of 1333Mhz is only an actual frequency of 333Mhz so you only need the RAM to run at 333Mhz(DDR2 PC5300)

There is no need for DDR3 if you aren't going to take the FSB past 600Mhz.
 
the way you look and memory bandwidth is the final clock speeds.

having a 1333fsb with 1333mhz ddr3 is true 1:1 ratio.

running a 800fsb with 1600mhz ram is a waste since the cpu cant communicate with the ram fast enough to make use of the full bandwidth.

How can a CPU FSB running at 4 x 333 and the memory running 2 x 667 be running 1:1?

Ignore all the marketing mumbo jumbo and look at the actual real frequencies.

A CPU with a quad pumped FSB of 1333Mhz has an actual real frequency of 333.3Mhz

So you only need PC5300 to run in Actual real 1:1 mode.

Running your memory at 400Mhz(DDR800) and the CPU quad pumped FSB at 1600Mhz is running 1:1.

How can you not see this?

Also why hasn't the naming scheme for DDR changed?

Original DDR266 to DDR400 ran at frequencies from 133Mhz to 200Mhz but compared to SDR transfered data twice per cycle

So why hasn't DDR2 had it's rated equivelent speed to SDR doubled yet again as it transfer 4bits per cycle.

DDR3 transfers 8bits(1 byte) per cycle

Look in CPU-Z and you will see it is 1:1

Its well known you do not need the FSB and Memory to be the same end MHZ, to do now would need DDR3.

You would need ask Intel what they use Quad Pump crap when AMD use Real Clock x 2 to get DDR Speed.

My Asus Mobo classed 1:1 as FSB same as Memory but all other APP's do not.

Its a fact you only need 677mhz Memory to match to a 1333FSB Intel CPU.

I ran a 2000FSB with Memory at 1000mhz on that POS Sticker II Formula I had, that is the correct way to run it, there is no way in Hell the Memory would have ran at 2000mhz.

The simple reason for that is.

DDR2 Memory Real clock = 167mhz x2 x2 = 667mhz (PC5300).
Intel CPU real clock = 333 x2 (DDR) = 667mhz, but its Real Clock is Quad Pumped so its 1333mhz.

Dude, what the **** are you on?

My old setup with ballistix DDR2

FSB: 400Mhz
Mem Ratio: 100%, 1:1 or whatever you want to call it.
Timings: 4-4-4-12

Thats DDR(II)-800, PC6400 and its running at 400mhz. The Quadpumped data rate is 1600mhz. The cpu with a 8x multi is 3200mhz.

333Mhz FSB needs PC5300 memory to run 1:1, thats DDR(II)-667.
266Mhz FSB needs PC4800 (IIRC) memory to run 1:1, thats DDR(II)-533.

End.

Less of the cursing and putting "END" as if you have the last word m8.

The facts are as I and Reality|Bites have put them.

Nothing changes that.

Could you give me a link to where you read DDR2 runs at "real frequncey x2 x2"

Always thought it was that, not sure where from TBH.

Must have read it long ago.

I keep a little table of it though.


SDR = 200x1 = 200MHz
DDR = 200x2 = 400MHz
DDR2 = 200x2x2 = 800MHz


Edit:


From Energize's post:

DDR 800 = 400 MHz memory clock, 400MHz I/O clock, 800MT/s

DDR2 800 = 200MHz memory clock, 400MHz I/O clock, 800MT/s

DDR3 800 = 100MHz memory clock, 400MHz I/O clock, 800MT/s
