In case somebody wants to try tCAS=5 for non-24/7-use, here is some motivation for you. :)
RAM air-cooled @ 1.92 V (BIOS), not 100% maxed out due to time constraints some weeks ago:

You are mad :P

hyper try that around 3.6 range and it will be smoking, but for the sub 16 min range it's not gonna cut it. around 3.9-4.0 you need to push cas 6 and higher ram speed.

Already did alot of testing with cas 5 range and it's performance tapers off around sub 17m range. I'll show you what I mean in a few.

Here, this should explain better.

@BeepBeep2: Yes, these are WS220UX4G8.
@chew*: Ok, thx for the hint. :) I am going to do some further tests and consider the performance.

btw does anybody know if there will be better/equal chips medium dated, when Hypers are gone? :/

Not really. At least, not a tight tRCD. Almost all the chips out there struggle to do sub-8 tRCD at 1800 or above.

Can somebody say if this is normal with G.SKILL ECO, mostly for the maximum frequency, otherwise it should be accurate.
I've seen chew*'s results and they are pretty close.

Here is a translated version from Bulgarian -> link

Looks normal.

With tRCD under 8 it just stops scaling.

You could probably try 6-8-6 and it would scale close to 7-8-7 results.

EDIT:

If you set tRCD = 10 I bet you just might get past 1800 Mhz. But then performance is worse than garbage.

6-8-6 is smth like 1600MHz max, but not tested thoroughly.
9-9-9 was enough for me to realize that it tops to something around 1800MHz.

Mine wouldnt boot with anything <CL8 above 1333mhz :down: (tried both 790FX and 890GX, P55 is fine:rolleyes:).... Guess i just got a bad pair:shakes:

you should focus on NB clocking first

how much for running NB ?
i use this set just for daily use..

The ECOs doesn't like that much voltage, you would gain nothing on that high voltage like 1.65v. Runing at 1.55v should be fine. I can do 900MHz with CAS 7 stable (passed 4 memtest for 20 mins) on both ASUS M4A89GTD and GigaByte 890GPA-UD3H with this voltage. Even 950MHz for 7-9-7-21-33-1T at 1.6V benchable on ASUS motherboard.

So set your TRFC to 110ns in your BIOS, and TRCD=8/9 clk for higher frequencies, that seems to be most fit for ECOs, and push your NB frequency as high as you can. It should do 2400MHz with stock CPU-NB voltage.

i set at 1,67 cause after boot have trouble with dumping :mad:
i hope i have new mobo for running more my eco..
i'm stuck at 860Mhz cause mobo limit :mad:

thanks for your tips :)

1.73-ish for benching

And here are some links to kits for those in the US who can not afford Corsairs $250+ prices:

Are those ALL Hypers? The prices are :shocked:

Does anyone have a list of Kingston RAM that uses Hypers?

I would say cl 6 is not.......I would muster a guess it costs more to make than the price.

I would say c9 2200 is not nor is 2133 c9.

I could be wrong but, i don't think so.

One more question :D

Kingston Hyper-X KHX12800D3/2G 2GB (1 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
Kingston Hyper-X KHX12800D3K2/4G 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600

According to the specs, they both use 1.9v. Could these really be old Micron sticks?

Don't think these are D9 since they are 2GB sticks, my bet would be on Samsung HCF0. :shrug:
