How expensive are we talking about?
EDIT: found, 200$ per 2GB stick. That is expensive :eek:
Are they sold as kit at all?
Yup 200 a piece, afaik only sold seperately. ;)Quote:

Would you rather go after:
Corsair Dominator GT

G.Skill Perfect Storm
Dominators are the most expensive, but if they are the best anything <250$ I can cope with.
G.Skill's have the highest frequency, tight binning too probably, but are even cheaper than the Corsair.
Patriot Viper are the cheapest due to absence of unnecessary fans, yet there is Vantage registration key.
Because they are going to be imported, I take Corsair has the best CS here?
Please take that into consideration, too.
They are all built around MNH-E Hypers I take. Which one would you go after?
Sorry about slight offtopic, I'd hate to open new thread to read a couple of replies which would help me
make mi mind.
Thanks :up:
If you want guaranteed hyper ics then Corsair Dominator GT are the ones to get :)
Hello,
I have a question about my Dominator GT's. I'm working with a P55 basis, so dual channel for me, but I hope you'll help me.
Here is my memory reference:
Question is:
- do you have some guidelines for overclocking this memory?
- is there somewhere a table with timings supported per frequency? I mean for daily use I'd rather like to run the memory @ 1600MHz, but with better timings. For example 1600 7-7-7-20 1T or better.
I'm a beginner in memory overclocking / downclocking, need some help is possible :)
Thank you very much :)
I think 2000 with CAS8 is tight enough. I don't think that 1600 CAS7 has a much greater bandwith, if it is greater at all.
Furthermore, on daily basis, you won't notice the difference.
Well I was guessing to reduce the voltage to 1,5 at lower frequency but with better timings to get same performance with better power efficiency. But I'm maybe wrong, am I?
I don't notice any difference in gaming or backoffice stuffs between 1333/1600/2000MHz memory... I'm only human. But in video compression for example, some seconds less... great but not absolutely necessary. I'm trying to understand how to adjust timings with frequency @ lower frequency.
First of all, I'd try to reduce vDIMM @ default speed and timings. See if it can be lowered, probably it can.
For this, not sure if it would be possible at 1,5v. Lower your speed using divider and set vDIMM to 1,65 with CAS7.
If it works, it should I believe, then try lowering your voltage on notch at a time.
Thanks for the procedure. I'll try the steps you recommend. I thought the default was 2000MHz 1,65V 8-8-8-24 2T... when you talk about default you are talking about the SPD values? I mean if I want to put frequency @ 1600MHz, I have to check if there is some SPD values for 800 and check the related timings ? Example with my memory: 1333MHz in the SPD tab of CPU Z shows 9-9-9-24 timing. But nothing with 1600MHz. I don't understand how is it possible to have worster timing @ lower frequency...but it is maybe because of the voltage @ 1,5?
I'll try this: 1600 7-7-7-20 @1,65V, then reduce voltage. Do you recommend to use mem test for checking if the setting is correct ? Or may I use Super Pi or Prime 95 to validate? It will probably take a while... but I'll try that way.
Some other questions:
- What is the benefit to reduce the tRAS?
- 1T and 2T what does it mean?
- tRC and tRFC is that the same thing? Because in the XMP profile the value is 51 but it's not stable if I manually put tRFC @ 51 into the bios (in auto mode, value is 98...).
There is maybe a tutorial explaining that, sorry for beginner's questions.
When talking about default we are talking about frequency, voltage and timings declared on the stickers which can be found on the modules.Quote:

Thanks.
These are Hypers, skip DDR3-1600 MHz and go straight to at least DDR3-1600 MHz 6-7-6-18 1T or even 6-6-6-18 1T and see how you go :)Quote:

Thank you very much for the recommendations, I'll test it asap. :)
But to make sure I'll really good understood what you explain:
What do I have to skip? Maybe 1800MHz?Quote:

Hi,
It works fine @ 6-6-6-18 1T. Configured in seconds, fits the 4.2 OCed CPU just fine. 20 minutes of Memtest multiple run simultaneously to load the ram @ 98%. No problem very stable. Here are the settings:
http://free0.hiboox.com/images/0210/...c8f864f08f.png
Now something very interesting: I have only one second difference between two superpi 32M calculations ^^
1st one is with memory @ 1600MHz 6-6-6-18-1T
2nd one is with memory @ 2000MHz 8-8-8-24-2T (reference value of the ram)
Both with same CPU/OC settings except mem timings, ratio and target frequency. Same OS (not optimized for benches, it's my daily used boot). Same temps.
8'55'' for the C6, and 8'56'' fort the C8 :)

The second screen shot has been done some days ago with the previous version of CPU Z. But I don't think it does matter ;)
I have a set of Dominator GT 2000 7-8-7-20 3x2GB arriving on Monday.
Using a GGBT x58 xtreme mobo/965 - I assume 2144 7-8-7-2T is faster than 1876 7-7-7-1T - please confirm should that be true?
For whichever should be faster - what would you recommend for settings, subtimings and voltages for stable benching PC Mark Vantage?
I am currently number 5 PC Mark Vantage on the hall of fame list, looking to increase my position - http://www.futuremark.com/community/...pcmarkvantage/
I have my Corsair Dominator GT DDR3-2000 6GB kit in my P6T Deluxe but it is only showing 4GB in the BIOS and of course in Windows 7. I've swapped the modules around with the same results. I tried another 6GB Triple channel kit and both the BIOS and Windows 7 show 6GB.
I know this Corsair Dominator GT kit worked in my P6T Deluxe as I've got screenshots to prove it. Any suggestions or am I going to end up with a RMA?
Sometimes they need a lil more vtt then. But if they worked with these settings b4, one module may be faulty. You could probably check, what module it is and try to boot with that one in single channel. Maybe do some memtesting and such. Often there are contact problems in the cpu socket as well, but i think you can rule that out as the other set worked.

They never were. I got mine from Corsair almost 1 year ago. And they still are only available there. These are the cream and handtested - no mass ware.

they don't mean much to us without knowing how much you are putting through them.

Saw ya on hwbot congrats on taking 2nd!
I have 6GB Corsair Dominator GT 2000MHz CL8, currently @ 1600MHz 6-6-5-18 with 1.65v. What's the lowest CL I can expect with these rams @ 1600MHz, while keeping vdimm at 1.65v?
6-6-5 is pretty much as low as they'll go
can try 6-6-4-15 or something in between but i doubt you will see any gain
Got a weird bug while running Sandra:Quote:

I just installed a set of Extended fins for my GT's. The fins came packaged with cardboard touching the thermal pads so they stick to the cardboard and are pretty much ruined so I used the stock fins pads. Idle they are all around ~30c where the stickers are on the dimms and I haven't test load on them yet. It looks cooler:rolleyes: but I would try anything to get rid of those noisy cooling fans.:cool:
Too bad they are $100 more than what I payed for them almost a year ago as more people should check out this ram.
You can do what I did. Buy two Scythe Mini Kaze 60mm fans to replace the original fans on the Corsair Dominator Airflow. They fit perfectly, work like a charm and, best of all, are silent as hell. ;)Quote:

Sorry 1.6v vtt DMM @ 4.2ghz seems awfully high and this kit won't budge higher than 1050mhz even with cpu at stock settings and relaxed timings. Looks like I may have gotten a FUBAR kit.:(Quote:

I need to ask several questions about this sets of ram CMG6GX3M3A1600C7 (7-7-7-20 @ 1.65v)
1)what's the difference between the new "CMG" kits compare to the old "TR" kits.
2)Heard that a lot of dominator GT faced premature death, but most of them are 2000MHz kits, so are this kits effected by the "premature death virus" also?
3)So far I googled, a small amount of people saying that this kits are not a better Overclocker compare to the old one, but nobody posted any proof for it so if anybody have this kits I need your help since it's a very expensive kit so I need to read as much of infos as I can to be really satisfied with it.
4)I'm interested with Team Xtreme 6GB 1600MHz CL7 kit but it's not available in my country for triple channel. Here's the question. Can i buy 2 of those Dual Channel and use only 3 of the sticks (keep or sell the other stick) + (I know it's dumb but it's way cheaper than the Dom GT kit). Is it possible to do something like that? Anybody tried this before?
5)Any extra advice regarding my ram issue.
6) My system is i7 920 D0 + DFI UT + HD4890 + TRUE 120 Push and pull~
Thanks in advance for all.
Question, do you guys use the fans that come with the kit? Is it necessary?
1)TR are the old sticks with the Hyper chips that die easily, CMG are the new sticks.Quote:
Originally Posted by madriddistas
2)CMG sticks don't die that easy, just the TR's.
3)They don't overclock better, that was never the purpose of the new rev. they changed over to a better batch of Hyper chips.
4)Yes, this is possible.
5)The 1600C7 Dominator GT's are Elpida BBSE chips and won't overclock half as good as the modules you see here in this thread.
I'd recommend it, or another fan. The modules run quite hot here.Quote:

I'll do my own thorough research about this particular topic but isn't there anything else differs triple channel kit from dual channel within the same spec Ram kits? The voltage, Overclocking capability or etc.. Mind explain it to me please.
Thanks in advance and thanks for your previous reply.
You can pick out any stick from a kit and use it in triple channel as long as it's the same type. Reversed is also true, you could use two sticks out of a triple channel kit to run in dual channel.
Matched pair is just a marketing gimmick. Matched in terms of what? Voltage? Timings? They're all the same sir. ;)
Zeus is right on the money. You can use 2 sticks of a triple channel kit on a dual channel board. I've done it myself, and it actually allows you to pair up the 2 best sticks of the 3.Quote:

Anyway, off topic I'm sharing with my friend to buy 3 kits of dual channel 2x2GB Team Xtreem 1600MHz CL7 to fit in our system. He's the same with me anyway.
I heard that Team is doing a great job lately with their kits for dual channel, so I say why not. :)
Thanks guys, I was planning on buying the "never will available GSkill Trident Cl6" kits and get tired of waiting and planned to buy Dominator GT kit but Zeus's post saved my money. Thanks again, I'll post the result when I got the ram.
I had to find that out the hard way, I wish I'd found this thread prior to wasting big $$$ on the 1600C7 GT kit :mad:Quote:

If you want tight timings get the Dominator GT 2000C8 or the 1600C6 kits, these contain Hyper chips.
You'll need to hurry though, Elpida Hyper chips are EOL. :(
I picked up a Patriot Viper II DDR3-2000 C8 kit from Frys locally, however those have the original J1108BASE MNH-E Hyper chips. I don't know if ALL the first Hyper chips die or just certain batches...Quote:

I'm really hoping for Elpida Hyper, but I doubt it.
:confused:
Corsair rep stated here Dominators GT 1600C6, 2000C7, 2000C8 being Hypers
and 1600C7 and 1866C9 are not. Not sure if I missed any, but 1600C7 are not Hypers, that I'm sure of.
Just clarifying, you're referring to the standard Dominators when you say mine aren't Hyper? Also, what are they if they aren't Hypers? Do they run fine @rated specs (haven't tried myself yet)Quote:

I was actually refering to Dominator GT. 1600C7 are not Hypers. Check the version number
on the sticks and consult IC inquiry list on Corsair's forum for details.
How do you mean if they run at rated specs? If they don't then they are RMA material :confused:
Yes Im referring to standard Doms, hence the TR at the front. Model is "Corsair TR3X6G1600C7D".Quote:

Those ones.
Same timings/clock as the 1600 GT's, but I'm hoping not the same chip.
Rated specs meaning can run 7-7-7-20 @ 1600. RMA material? Not necessary. Some 2000MHz kits are harder to run @ rated specs, 2000 9-9-9-24 (or whatever it may be) due to the fact you have to up volts, but I guess thats what you get for getting high speed ram :P
Edit:
Btw there are 1600 GTs that run on the Hyper chip
"CMG6GX3M3A1600C7"
Some of those C7's are Hyper, some are not.Quote:

As said numerous times before-check the version number on the stickers- version 2 are Elpidas, and 2,1 is normally Hyper IC
TR C7 Ver2.2 hereQuote:

Okay thanksQuote:

Is there a way how to tell whether the memory or the IMC is the culprit when prime crashes?
I can't seem to hit 2000 7-8-7. Setting CR to 2T helps with stability, but not completely.
It's an i5, guess it might be weak IMC :(
It depends how the chips behave, you have the following types according to eva:Quote:

- some are needed no less than 1.65v for 7-8-7-x but don't handle 7-7-x-x timings well at DDR3-2000Mhz but scale at 7-8-7-x to well over DDR3-2100-2200. Not much different in max frequency for cas8
In my opinion you might be able to hit 1750-1800 with up to 1.7 vDimm. :yepp:

As far as I'm concerned, if a Corsair representative says ver. 2.1 is Hyper, then it is. I see no reason why there would be two different IC's used in "Ver. 2.1" If the IC is different, then they change the Ver. number.
yeah it might be hyper man, test it :D
but yeah read yellowbeards comments it might not be
