OCZ2B1200LV4GK - the best DDR2 kit in the world?

Elpida
Not worth a dam.

Statement of the month.

They are half the price of the PI's, don't expect them to take you to Mars and back...

[devil_mcry]

in a review on internet and one users of hwup.....e.it has overclocked this kit at 1280mhz 1.9v RS

it's not bad for only 90€ (i don't know how much in us)

[WaterFlex]

1200MHz or 1300MHz is the same
I have 8 Gb DDR2 RAM at 1200MHz with 10000mb/s. Thats great for me

[devil_mcry]

y me too 1200mhz 5 5 5 15 at 10066mb/s XD

[Don_Dan]

1200MHz or 1300MHz is the same

I can't really agree with that statement!

[zsamz_]

I can't really agree with that statement!

+1
neither can i
1300 is somethin else

[slim142]

I think he meant 50Mhz extra per stick wont give that much of a gain

But yeah, they are not the same

DDR2 can reach slower DDR3 spec. I think DDR2 upper limits are around 1333, 1400 with OC. Manufacturers have no interest in doing this with 4GB kits though - they go where the money is, and thats with DDR3.

[BeepBeep2]

How far does properly made DDR2 do with CAS 7?

Some kits can do 1300+ CAS 5, a little more with CAS 6 but what if motherboards and RAM kits were tuned to do CAS 6 / 7 / 8 like DDR3?

[Don_Dan]

Only some ICs show a benefit from going to CL6, and that is often very small.

And concerning going even higher for CL: I was told that DDR2-ICs don't work with higher CL latencies, they just don't support it.

[Ket]

DDR2 will never do CAS 8, and probably never CAS 7. With CAS 6 however (this is back when I done some stuff for Mushkin) I was told DDR2 could reach beginning DDR3 spec. Its extremely unfortunate manufacturers are so quick to abandon a technology before its reached its maximum potential. Theres still far more DDR2 based systems out there than there are DDR3 based systems. Another advantage with DDR2 is efficiency. Due to the tighter timings bandwidth and overall performance would (read: should) be better than equivillent specification DDR3.

I checked the first kit, CAS 7 1066mhz and 2.1v? Is that even worth now?

Probably the worst group of RAM on one page I've ever seen.

Funniest stick of DDR2 I've ever seen:

Perhaps not.
The generic Crucial @ 1.8v could very well be some really decent unbinned stuff.
In fact, IIRC, D9JKH is actually JEDEC DDR2-1066 7-7-7 1.8v.
So with some luck, some of the 1.8v Crucial is likely not bad at all.

The other kits with 7-7-7 @ 2.1v = disaster, yes.

Low profile stuff, yeah.
Nice for mini-systems.

[Don_Dan]

So please, someone has to by 10 kits of the Crucial memory with D9JKH and start binning them!

I have never seen those high CAS stuff in Germany, the only memory I could find that doesn't use CL5 were some 2GB DDR2-1066 CL6 sticks. I would be interested in some performance figures of DDR2 running 533MHz at 7-7-7-20.

loool XD how many kit of ram do you have XD

Not enough yet... There are still two or three kits I would like to have.

How about these: http://www.newegg.com/Product/Produc...82E16820231111

2GB @ DDR2-800 6-6-6-18 with 1.8-1.9V

The other kits with 7-7-7 @ 2.1v = disaster, yes.

Nothing to add.

The only memory that might be interesting are the Crucial ones with D9JKH just like -n7- said.

[WaterFlex]

Are there any more owners of this amazing kit ?

[devil_mcry]

today i tried to study a real minimun timing for this ram at 1200 with stock voltage (1.8v)

i think it

cl 5
trcd 5
trp 4 but this setting haven't any impact on performance (from my test)
tras 15
trfc 50 (from 54, just a little improvement on bandwidth and latency)
trrd 3
trtp 5

pl, twr and twtr are relative to fsb and divisor i think

what do you think about this? other test?

[kuebk]

Have any of you guys tried lowering the tRFC at 1200?

...or seeing it tighter timings are possible at 1200 such as 5-4-5-18 or 5-4-4-18 etc?

Would love to see some screenies if possible.

Higher tRFC won't help you tighter your timings but will increase read.

[Erklat]

Don't think fiddling with it too much is neccesary since it won't have a great impact on performance,but might make one stability wise.

[devil_mcry]

now i'm sure

change trp from 5 to 4 at 1200 can decrease performance (but realy not much)
change trfc from 54 to 48 can increase performance (just read and latency, but not much)

is it possible to go under 48?

ah

TRFC depends on the NB or RAM?
