Corsair TWIN3X2048-1800C7DF --> Setup & OCing on P5K3-D, P35T-DQ6 and Blitz Extreme!!

It took me a bit longer to move forward with what I have started here as I got caught up at work with other stuff...

Anyway, below is pretty much as far as I could go at spec'ed 7-7-7 timings and at the same time maintaining enough stability for at least Dual SPi32M to pass. For OCing results below I also went ahead with tCMD=1T. Just heads-up, CPU-Z 1.40.8 and 1.40.9 incorrectly reports 1T when actually 2T is used; then it shows blank space when in fact 1T was set in BIOS. Therefore MemSet and Everest are opened to show correct tCMD timing. Also, our E6850 here is not yet a bottleneck here as with this cooling it's capable of passing DualSPi32M at well into 39xxMhz and around 520MHz FSB.

Asus P5K3 Deluxe

Dual SPi32M - DDR3-1916 7-7-7 @ 2.25v

For those that don't mind the level of stability, I have also run some SPi1M and bandwidth benchmarks at frequencies/timings that approach about the max for this particular kit:

SPi1M and Sandra XI - DDR3-1972 7-6-6 @ 2.25v ------ Everest Ultimate - DDR3-1980 7-6-6 @ 2.25v

I would also like to point out that this 2x1GB kit I've been using is I think neither the best nor the worst. It seems to be a fair representation of what our the batch of 1800C7DF that's shipping could do.

Thanks again for dropping by guys,
:toast:

You are going to love the numbers I am hitting :D

Yes, 1T results are looking pretty good, although the only benchmark that shows the biggest gains is pretty much Everest, ~200-300 MB/s.

Well, that depends on what level of stability we're talking about and amount of modules used. I can boot at DDR3-2000 7-7-7, but it's nowhere near stable. I wish it was, at least for SPi32M :D That would rock!

Thanks man! I'm just trying to be useful for those of you interested in this 3rd generation DDR memory.

Actually, I will do that later this week with QX6850 ES.

Thank you! :) Asus P5K3 Deluxe is the board I spent most time on, although Blitz Extreme has the widest range of available voltages and P35T-DQ6 is now a really good performer as well. But P5K3 has been a very solid board from the get go. Gigabyte's board used to have hard time going above DDR3-1700 when we had been showing it at Computex, but with the latest BIOS it now looks very strong - 500Mhz FSB is a snap with a right CPU and memory speeds above DDR3-2000 totally within reach. Hard to decide, really...

i am hoping to get the gigabyte to test the 4GB kit :)

Well, yeah it's been fun, really! But also some hard work, believe me :)

Great.. i love this kind of thread :)

hahaha i'm sure it has

shame that Gigabyte does not have selectable command rate

i shot off an email today asking for a few superpi related bios settings to be included including command rate for the Gigabyte board you tested as i've got one here too

we'll see what happens :D

awesome review michal!
good job! :toast:

EDIT: what about the blitz CL?
Could it be a buggy run?

ahum! :P
michal?

Damn, nice review dude! Your setup rocks! Are you working for Corsair now? :D
I can't wait my DDR3 setup.

Which mainboard would you prefer for allround?

He's not only working here, he's like the hardest working guy in the lab. He won't even leave for lunch!

The guy is an absolute overclocking monster.

Haha, that's is a good thing, memory is very addictive. :rofl: But I would strongly recommend him to have that lunch. :yepp:

guys, michal is from poland :D
but he works like a german, thats true :lol:
very systematic and very detailled, and he never stops.

when i worked at amd i was usually the last person in the building, besides the security guy hehe :D here at cellshock everybody has to leave the offices at 5pm... insurance and security policy or something... if it were up to me id probably work until 1 or 2 am like at amd :lol:

lol sorry about that Bachus....i guess i assumed wrong lol

now that's germany for ya though :D:ROTF:
if you stay a minute over work hours a couple of German shepherds will attack you and rip you to bits :D

lol 1 or 2am
surely you aren't having THAT much fun at work :D

my attitude to work is if you can't achieve what you set out that day in 8 hours you'll manage fark all after that.....:p:
