What's your settings,board, voltage?
What's your settings,board, voltage?
on a 920,r2e
if i can run 2000mhz CL8 fine with no errors at qpi 1.48( set 1.53750),dram 1.65v,bclk 200 and also tested the xmp profile also
which was 1.6v for qpi set 143 something for bclk
all dram voltage at 1.65v
pumped dram to 1.67 also no luck.
is there other settings for a latency other than dram voltage??
if i was to run 7-8-7-20
end up with 4gb left
and if stressed fails immediately with hci
Unfortunately this is going to be the outcome for quite a few users. The Elpida Hyper based sticks can provide more performance then a lot of processors will be capable of running at. At least you are able to run at 8-8-8. Some won't even see that.Quote:

dont u think thats kindda thin as so far only uncore speeds are the issue with imc's and qpi voltage limits.
when the ram can run 8-8-8-24.. at 1.65v.. exact.. if i lessen it even by one voltage.. it gets unstable
isnt the problem with most proc is the ability of running uncore 4000 with the ram 2000mhz
i am still heading that this ram wasnt binned at 7-8-7-20.

see the 4gb issue when cl7 ..
i remembered when i was clocking my dominator 1600 CL8.
when i did adventerous timing that doesnt have enough voltage only the issue above happens
Thin? Not the term I would use. The memory controller is part of the CPU. A weak controller will result in weak ram overclockability. Even though the ram is rated at 2000 running at that speed is overclocking the controller. With enough VTT you may find stability at 7-8-7. However, may well be past the voltage limit one is comfortable with.Quote:

Ok, let me rephrase then. Ordering from US means that i have to pay 19%VAT once for the product when i order from you and 19%VAT once more in Greek customs over the total invoice that comes from you (Price of ramQuote:

Do you have experience with all the kits and state your opinion? :shrug:Quote:

i7 memory quality not only effects frequency head room but ability to run certain timings so you have 10x core i7 cpus where only 5 or 6 of these cpus can do DDR3-2000Mhz at CAS7.Quote:

These kits are validated at 1.65v vdimm and 1.6v CPU VTT (uncore) volts.
Right now I'm working backwards for my tests starting with max intel spec'd 1.35v CPU VTT and seeing how my GTs scale as i bump CPU VTT (vdimm is no longer the sole factor determining memory frequency/timing overclocks)!
ok lets assume i tried everythingQuote:

i have used the vtt up to 1.65v and no diff..
the errors still there
the errors lessen only when i up the dram voltage.
i am not yet comfortable to be running my vdimm voltage past 1.7v for stress testing yet on i7. but the errors are less around 4-5
this suggest only that the ram is not binned at CL7.
i have been running the other dominator at 1600 CL7 for nearly two months.
to answer the other question
the vtt voltage is just for the uncore not for the ram timings.
y the possibility that this set is not binned at cl7 is not a acceptable explanation.
i find that odd. latencies has nothing to do with vtt unless somebody here can prove that
so eva ure asking me to change the difference.. ok will try again..Quote:

so i see ure point but up to what voltage should i run on the vdimm for 2000mhz CL7.
pinto the tRFC is set to auto.
never saw much of a gain from lowering it in x58 as compared to RE.
Very good explanation George. I'm still wondering how memory manufacturers are going to handle this. Compared to past platforms there seems no sure way for the average user to isolate these types of issues down to the memory itself. At least a method that will convince the user that it is not memory related. It's going to be a headache for the manufacturers for sure.
also are u guys so sure that instead of doing the above that
its just not bad luck that my kit cant run CL7
testing with lower vtt with memtest86..
hmm interesting 6gb now detected.
hmm so far no error in test 5 like above.. hmm
sorry praz for being a idiot.. just was pissed..
I didn't take your post as anything that needed an apology for. There really needs more info put out concerning memory and processors. Nobody is going to be happy if after spending upward of $500.00 the memory won't run at its rated speed.Quote:

vdimm is a secondary voltage to play with really as it's all in the cpu vtt volts first and foremost - unfortunately cpu vtt comes down to the individual cpu.Quote:

My GTs do quad super pi 32M around 20x 188bclk with 10x mem multi @DDR3-1880mhz 7-8-7-20 1T at 1.65v when i restrict CPU VTT to around intel spec's of 1.36v CPU VTT versus Corsair's validated 1.6v. Still testing how it scales in terms of CPU VTT.
Would definitely love to test more 6GB Elpida 50nm Hyper based IC kits later on, to see if it's specific to my i7 920s cpus, board/bios or GT modules itself or a combination of factors.
Only one way really = education :) More of same/similar information getting out to the masses is only way. Raja and Gary at Anandtech also touched on this with CPU VTT differences between Core i7 cpus http://www.anandtech.com/cpuchipsets...oc.aspx?i=3502. CPU and MEM performance/stability on i7 seems to be linked hehQuote:

it can be a fine balance so far come across 3 types of core i7 cpus from my rounds on forums and my own experienceQuote:

Type 3 - core i7 cpus that only like low-medium low cpu vtt to overclock for memory and bclk BUT DO NOT scale for either cpu vtt and memory voltage or both
low cpu vtt = 1.3-1.35v
medium cpu vtt = 1.35-1.5v
high cpu vtt = 1.5-1.55v
very high cpu vtt = >1.55-1.65v
memtest is only the first stage of testing - next is windows :)Quote:

difference is i increase the vdimm to 1.67
reduce the vtt to 1.5187set
6gb detected..
first thought must be the ioh/ich pair again
memtest hci prooved only stable when vdimm at 1.72v
testing now with a 965xe.
i am convinced that this ram is not binned right no offence folks.
It may well be the ram. I think all we are trying to say is without components that one knows well it's difficult to isolate the issue to a single part.Quote:

Believe it or not, 40mv on Elpida Hyper may make it or brake it @ 7-8-7...Quote:

I'd like to assure you that we put super-super-extra care into manufacturing and testing Dominator 2000C7GTs.
What Praz and George said regarding perfectly matched CPU/mobos is very accurate, and anticipating that we put together some notes included with every 2000C7GT your kit as to what to expect when DDR3-2000+ clocking at 7-8-7.
Dominator 2000C7GT is a bleeding edge product that we target towards very particular audience, who understands Core i7 memory overclocking well, and is ready to spend some extra time tuning their setups. I'm not trying to lay blame, far from it, but only to point out that with 2000C7GT on Core i7 there may be more to it than just plugging it in and have it work, as we approach the limits of what Core i7 can handle without going sub-ambient on CPU on it to improve memory overclockability.
I'd like you to be satisfied with 2000C7GT... But if there's a doubt in your mind, we will take it back - replace it or refund it.
Thank you for understanding.
i am quoting from a dmm on voltages on load.
testing now with a 965xe. just took it from the office. since my friends 965xe also prooved the same.
i really trying not to rma it bachus.. as it took heck of a long time to get here and sending it back is just another cost of shipping for me.
hmm will get the dfi tommorow since the stock just came yesterday for the ut and dk.
:( I see what you mean and I am sorry to hear that. Perhaps in the future we can better serve our customers online. Our store is very new to us so we have plenty of room to improve.Quote:

went over to dfi
and guess what no prob running 2000mhz CL7
stupid r2e..
two boards didnt work.
I had similar disappointing experience with 2000GT kit on Bloodrage until i got a bios update(G19a). Now runs cas 7 no problem.Quote:

So when are the memory water blocks coming out?
not going to run futher until get a waterblock for that pwm
http://i287.photobucket.com/albums/l...2000mhzCL7.jpg
I know this has been asked before, is QPI/VTT voltage of 1.6-1.65v safe
and what should the IOH core voltage be set at ?
For that matter what is safe volts to run CPU PLL? " under water for the cpu and qpi north bridge thingy "
Hello Guys,
on this Weekend we have our Live OC-Session on CeBIT '09 here in Germany at Corsairs booth.
We have to work with the DOMINATOR-GT 2000C7
after the Weekend Bluebeard gives me this f***in nice memory to test it at my place and have one week fun with them.
Here are my Pics:

Yesterday I test them on my EVGA Board.
Works fine, but they only do what they must do...
need 1,8V for 1050 7-8-7-20 1T in 32M
will continue testings today :up:
I also have a Bloodrage, what VTT did you need to reach 2000 @ cas 7?Quote:

We have made a little Video about the TEC Cooling of the CORSAIR DOMINATOR-GT's.
http://www.abload.de/img/introi4ut.jpg
Klick on the Picture for Video!
in our case the TEC Cooling gives us a gain of 15-20 MHz (on 7-8-7-20 1T 1,8V)
:up:
I can reach 1053MHz 7-8-7-20 1T @ 1,8V 32M Stable but more isn't possible
WHere are these in stock at? Corsair's website says they are out of stock/unavailable.
Its only Corsairs e-shop that sells these at the moment.Quote:

Thats what I was thinking. I guess i'll have to go on their notification list. *tear*
Any clue when these TEC kits will be available?
I went on there notification list and got a link through saying i could order at certain time but then the link didnt work, bought these since but only the 8,8,8,24 kit , will run at 7,8,7,20 at 2000 though so more than happy.Quote:

If you're interested in what we've been up to, and what came out of it :), click on the image to watch a video I cooked up :D
As far as I've seen around, some current triple-channel DDR3 frequency records fell in this video - top DDR3 frequency in triple-channel 3x2GB configuration and max. SuperPi 32M stable ;)

Within days another batch of 2000C7GT is to land in the Corsair Store, and waterblocks should make it at the same time as well. We should also have TECs available in the store within 2 weeks. Sorry for delays - we're making sure all is tip-top before we release it into the wild.Quote:

CPU runs nice, up to 4,6 Uncore 32M stable on Cascade but with Samsung ICs 1075 CL8 was also the max. have tryed a lot of combinations with the EVGA X58 Board but no possibiliy to get over 1053 32M stable
hope we will get a nice D0 in the next weeks, so I can push the memory higher, but unfortunatly the 2000C7 are no more here...
Great work Bachus, really impressed. But uh Bachus, damn what a hard job you got testing all these ram modules with your 10x i7 965's, its a hard life eh but someone got to do it :DQuote:

7-8-7-20 1866?
8-8-8-24 2000?
There both the same price but the 1866 is in stock. Does it even matter?
what I have heard booth are the same (Chips what not runs 2000 7-8-7-20 2T @ 1,65V) and only the SPD-ROM is different
For Elpida, 2400+ CL7 is not that hard. It depends on cpu.
I can confirm on DFI UT X58-T3EH8 with 2/27 beta bios that ADDR/CMD Bus VREF bios option did help me get single super pi 32m stable with ADDR/CMD Bus VREF = 95 when it wasn't stable (reboots) with default ADDR/CMD Bus VREF = Disabled @DDR3-2140Mhz 7-8-7-20 1T with 1.61v CPU VTT and 1.875v VDIMM.Quote:

My qpi is set at 1.6 in the bios, altho my volt monitor says 1.54, anything under that i cant boot at all..
Got my drammv 1.65, cant get them to run on 1T tho, should i set dramm volt higher to run at 1T ?
is there much difference between 1T and 2T ?
Id try lower bclk with other divider to check if 1T and/or lower vqpi is possible, 200 bclk is a tricky setting.
are the water blocks a corsair block or 3rd party block (ie EK water block for the ram) ?Quote:

It seems that all DDR3 except for corsair and kingston is much cheaper at the moment.
How much of a performance hit should I expect if I run 2 of the 6Gb kits?
For example, would I be able to run 12Gb @2000MHz 8-8-8-24 on an EVGA Classified board?
Or am I pretty much guaranteed to have to run slightly slower than that with all slots populated?
I was reading the anandtech article on the classified and they stated that that motherboard is better at having all memory slots occupied. You should get much better memory bandwidth than just 3 sticks atleast....

I am also interested. ;)Quote:

I gave them my e-mail addy. How do I "make sure I'm on the waiting list?"
Thats all you can do. I've went as far as using 3 email accounts. I received a tracking number within 3 hours of purchase. I wish you luck man. I've waited a couple weeks .
What...i never recieved any e-mail from them. I have done so before but on the 1800 set. Bachus mentioned they'd get some stock in last week but i have yet to see any online.Quote:

Probably resellers are buying them from corsair shop and selling them:p:Quote:

This way when I do make that transition it will be that much cheaper. Thanks in advance! :up:
It will work but the max voltage for the DRAM will be higher than 1.65v (I would say stay under or around 1.9v if you want the kit to last you awhile)Quote:

Beautiful!!! GT very cool
Well, my 2000mhz 8-8-8 GT's arrived yesterday. Not had long with them so no extensive results yet. But i got them up to 2000mhz and I'm pretty impressed so far!

I can get 4ghz Prime stable with the GT's at 1910mhz absolutely fine. The above settings are taking considerably more uncore I think, which leads me to a question. How much is too much uncore for 24/7 use?
Taming the GT beasts on DFI UT X58-T3EH8
Did 2 runs on fresh Win 7 64bit RC install I did last night. Only change was CPU VTT voltage needed to pass Hyper Pi 8x 32M vs 4x 32M.
- 8x 32M Hyper Pi HT Enabled - CPU VTT = 1.44v
- 4x 32M Hyper Pi HT Disabled - CPU VTT = 1.47v needed more for 4x32M HT Disabled
RTL value for channel A changed when CPU VTT changed from 1.44v to 1.47v
RTL A/B/C = 56/57/58

RTL A/B/C = 55/57/58

Past bioses and tests, I found memory bandwidth in memtest86+ v2.11 was higher with HT disabled than HT enabled, so could explain why more CPU VTT volts is needed for HT disabled.

Hello Guys,
on Monday I recived our new GT 2000C7 Kit
here is my first test result from today with only 1,8V
http://www.abload.de/img/2000c7-testingeobi.jpg
Any 2000GT7 kit can do this or not?
Mine can't at 7-7-6-x but it could be memory controller related. Either way at 7-8-7-20 1T still faster 32m time than that 7-7-6-20 heh.Quote:

Thats interesting. Can you kit do 7-7-7-20 1T on stock voltage?Quote:

That seems 7-8-7-20 1T really faster in 32m then 7-7-6-18 1T. Interesting observation.Quote:
