CORSAIR CMT6GX3M3A2000C8 - 2000 8-9-8-24 1.5v

[cstkl1]

Testing this kit atm.will post some of the proofing of result
But up till now impressive. WIll try 12gb if my proc imc can take it

so lol this sticks are pretty good and not that pricey
this are way better than supertalent 2200mhz CL8's 4gb kits or 2000mhz CL8 hypers or 1866 CL7 hypers
heck they are the closest to 2k C7's Hypers except u have a higher tRCD

did you take off the heatsink?

would be great if they can do 2000 6-9-6-21 with not too much volt

nope didnt do that.

from the voltage scaling
it will hit 1800mhz CL6 at 1.65v (Guessing )

i have some gskill 2k CL6 atm but hmm having issues with that ram on bloomfield on this board and R3e ( 930)

reason for posting since no one actually showed what this rams can do.

here is my qualms on the Gskill Cl6 on bloomfield
yes it can run 2k C6
but has anybody tried running it on the lower rtl which should be at 49/50,52,54 for uncore 4k??

theres a few things weird about PSC.
they dont like tRCP above 6 on evga ( R3e np)

Nice test- but how can you say they are way better than the kits you mentioned above? Have you tested these yourself? Main reason I´m asking is because I don´t have a 1366 system, but these 2150 above aren´t that hard to beat with reasonable Hyper- at same Voltage, just 8-8-8- on a 1156 system- and my Team 2200 did the 6-8-6 1800 with 1,5V

[Hondacity]

psc can have really good bandwidth.

cstkl1

can you do everest runs? it shows latency..read and write...speeds

ure serious right
normally vdimm to vdimm of a 1156 and a 1366 are around 200mhz off.

anyway here is some dom Gt's hypers 2k c7's that does on 1366 at 1.62v at 7-7-7-20
and does 1800 6-6-6-18 at 1.64v
trust me a 2200mhz CL8 1156's are same as a 2k C8 hypers 1366's

the 2k c7's can do more than 2200mhz anytime on a 1156's

here are some norms for hypers under 1366
7-7-7-20 ( april revisions) do them easily with the same voltage as the 7-8-7-20 but will hit a scaling wall at 2100mhz
7-8-7-20/7-7-7-20 2000mhz CL7's will do 1600 6-6-6-18,1866 7-7-7-20/7-8-7-20, 2000 8-8-8-24 at exactly 0.1v less than the voltage needed for 2k C7
scaling up to 2100mhz .. every 50mhz is a increment of 0.04v

this is how we judge good scaling on fixed timings how far it will go on scaling of every 50mhz on 0.04v..
when a timing adjustment will be needed

for hypers at 2100mhz above,, u have to change the write to write (same rank) and read to read (same rank ) from 4 to 6 which will take about 1000mb's off the read in everest with a slight dive on latency

psc can have really good bandwidth.

Very interesting- maybe I will have the chance to test myself in the future- the 900 6-8-6 with non Hypers Team Group were on an X38^^- indeed my 2000 C7 do a little better than the 2200s, hit about 2300 32M 8-8-8-24 1T at 1,65V on a P55, the 2200s only reach 2280 at same V and Timings

hmm past experience on 2kc8 sticks which is the same as the 2200mhz cl8's on 1156's
they normally do 2kc8 at around 1.56vdimm
so the difference is around 75mhz difference on a c8 scaling of a c7's
so u should have gotten more out of the 2kc7's

this is the norm for 2k c8
http://www.xtremesystems.org/forums/...d.php?t=224040

its norm as normally the 2kc8's just dont pass the 1.65v requirement and hence normally at around 1.66v for 2kc7 and they are about the same as a 2133 8-9-8-24 sticks

[websmile]

Interesting indeed- the system I have is my first 1156, with an i860, I bought is used so I really do not have much to compare- but I know from the guy I bought the bundle from that his Kingston 2000 C8 with Hyper needed around 1,65V V for 1050 C8-8-8-24 on the board, and 1,74V for Cl8-8-8-20-60 1T- being used to always having had two DDR2 Boards to check my D9 on different systems this is now a new and sometimes frustrating experience because I can´t be sure what my rams are capable of

[Oliver]

did you take off the heatsink?

Corsair bakes the DIMMS with HS attached for optimal contact . Trying to remove it will rip of the ICs (or some of them) = killing the DIMM.

So its highly recommended, to let the HS stay on

[sup3rfly]

i have the same kit but i didnt do linx on it, just superpi 32m.... 1.66v vdimm, 1,455v vtt... didnt really touched much on timing, just 2144 9-10-9-24, may be increasing the vtt might help a bit, will try it later as i m pretty busy nowadays to really test these kit thoroughly...

None of my Hypers scale anywhere near that well, and I have a kit of STT 2000 C7. Then again I can't get them to do 2000 C7@1.65v so maybe they just aren't good.

[Barr3l Rid3r]

Mine 2200 C8 does 1800mhz C6-7-6 on AMD 790fx old board, Am I missing something? I doubt this new corsair can go anywhere close to it.

This is how all the ram scales that i have tested on x58
2k C8 at say X voltage means 1600 C6,1866 C7 at the same voltage.
2k C8's dont pass the 2k C7 1.65v requirement usually by 0.01 to 0.03v

another thing hmm board's
ure limited by ure board's preset timings at fixed dram multi's

IMO
theres a few things Asus boards are better than say evga and dfi.
they run 12gb kits easier at high speeds.

it does, if ure 1800 C6 /2200mhz C8 are same voltage on dual channels..
then this kit will do that at much lower voltage except a higher tRCD.

some ppl are darn lucky to have gotten the last few rma's in corsair for the elpida hypers and they got a 2k C8's that are same bin's as 2k C7's

this kit that i am testing behaves exactly the same as a 2k C7 hyper kit
except it has a higher tRCD

hence the 2200mhz C8 u have is just a 2k C8 equivalent to me.

this ram will blow that ram away except it has a higher tRCD. its the closest to a now eoled hypers 2k C7 corsair Dom GT's

thumbs up corsair.

when you mentioned the 1156....what cpu did you use?

thanks

thanks again...i got the lynfield and a 920 ...i'll try duplicating your stuff..hopefully my imc is good

[websmile]

Maybe the problem for me is that I don´t have experience with the 1366 and because of this I can´t compare my 2200 Cl8 to your tested Corsair- but I doubt I would be willing to trade the STT against this kit- mine do 2208 at 8-8-8-24 1T with 1,6V Memtest86 stable, meaning they are windows 32M and Memtest 4 stable at 1,62V on my modest UD5 at Auto-subs, so as long as I haven´t tested the Corsair 8-9-8 I´ll stay with my SuperTalent^^

.

Oh in that case then yeah my 2000 C8 sticks will do 1600 C6 and 1866 C7 at the same voltage. I just wish I had a better bin of 2000 C7.

[ghost_recon88]

So there are PSC chips in your Dominator GT 2000? So if I have to RMA my 2000C7 kit, then I'm pretty much SOL

yup
no more 2k c7's

thumbs up corsair.

2k C7 can do about the same as mine super talent, is just a matter of lucky, one of my friends could only reach 2050Mhz Cas7 w/ his Dom GT, while w/ the STT he could reach 2100 Cas7-7-7 at the same voltage.

I'm at AMD so TRCD is very important to me, anyway I still prefering a BAD Hyper than a good PSC one.


1800Mhz C6 was done w/ 1.68v, I still doubting that this Dom GT C8-9-8 can touch anywhere near this, even if it can reach 1800 C6-8-6-21 at 1.68v I will be impressed.

hmm again dual channel vs triple channel 1366 is a big difference

and 2100mhz Cl7 under 1.65v.. on a elpida hyper on air..
that is something i would love to believe
the best i have seen was SAE's. and that was at 1.66v
the two gtx2 which i used one stick from my c7's also does that.

the rest all do 2100mhz Cl7 at 1.68v

so not sure whats ure friend is smokin.

1.65v that gives 1.66v in read... and that was 7-8-7 on both of them not 7-7-7 , that wasn't stable in the GT 2k 7-8-7 also.

where do you max out at 6-8-6 1.68v?
