Do you think its real CL4 and have 4-4-4-12 Latency

[deparist]

Hi to all,

 

Well, I bought a pair of TWIN2X2048-6400C4DHX total 4gb 4 sticks, few days ago from the store where I live, in izmir/Turkey, as you can find their website

url at the bottom line of this thread.

 

I have paid almost 300 usd for those 4 sticks which were made me happy

with their nice appariance with the heat spreader on them. Hmmm...impresive

shields over them.

 

Well, it seems abit expensive to pay for those sticks but It might worth to pay for a set which was low latency memory set I thought.

 

And I came back home happily and hopefully it would run faster then I thought, coz they are low latency which is called 4-4-4-12...Wow.

 

Installed them, and I m syill happy that had no problem at all till I ve droped down to this forum.

 

Didnt think to chek out the specs from the bios till I see that they suggest Lavalys Everest tool which is so cool that you can even have benchmark whole the system you have.

 

You konw what? It says my memories have the latency 5-5-5-18, not even 5-5-5-15. However it still says that the latency of the memories is 4-4-4-12 on the label as infact on the package, and the add specs at the stores list.

 

When I went deeper down to this forum, I found that they call it it is the test speed...LOL.

 

Well, I wont go further here just because of the forum rules, I just would like to say that I will return those beautiful sticks back to the store and happily would like to buy my favorite brand which I m not telling it here but 27 usd cost for each stick, more then %50 cheaper then those ones.

 

Happy overclockings to you all, with 4-4-4-12 sticks.:-)

 

Here is the store where I bought those CL4 sticks.

The tested speed IS the rated / guaranteed speed.

 

1. They are guaranteed to run @ 4-4-4-12 with 1 PAIR, 2 PAIRS @ 4-4-4-12 is not guaranteed, as they do not test this way, and most memory controllers (in your mobo or CPU) need the speed / timings to be loosened when running more than 2 sticks.

 

2. When you were checking out the timing info, did you check under SPD, or memory info? SPD is a STATIC setting that does not reflect what your memory is actually running at, whereas memory settings is what your memory is actually running at.

Hi, and thank you for you for your repy.

 

But, I know it can be overclocked to 4-4-4-12, as I can see at SPD settings.

In fact I m not saying that it cant be.

The main problem is, Corsair announces that those sticks are at 4-4-4-12 instead 5-5-5-18 on the package.

 

God knows how many people bought those memories as they are 4-4-4-12 default timing. And they might still thinking thet they have 4-4-4-12 memories on their setups. We end users dont have to go to hundreds of hardware forums, that which part is the best which is not. We just beleive

in what they say on their box or on the packeges.

 

And I dont have to download such a program that scan my system and will say what speed I bought. I just want to beleive what it says on the package.

 

This is the first issue I ve met in about 12 years computer experiance.

Shame on you Corsair.

[Wired]

It's not overclocking when the company GUARANTEES those timings. Setting timings manually is not new, nor is it limited to any particular manufacturer.

Exactly what he said. You have two paris, for a total of four modules. Almost all motherboards cannot handle having all four DIMM slots populated.

[RAM GUY]

Bottom line if our modules will not run at the advertised spec in an approved platform we will be happy to replace them. That being said, there is no way we can guarantee that every MB even the same model that's listed in XMS Qualification and Testing will be able to run with really tight timings! Or if you running them beyond the tested spec. There are just too many variables that enter into the equation and may have an affect on the end result, like the PSU, and if you suspect the PSU I would suggest you test with another one, and one that is at least 500 watt or bigger!

When trouble shooting it is best to try and simplify the problem and test things one at a time, and if you suspect a given part, then try and verify your suspensions by testing that component in another system! In this case you suspect the memory, then I would try and test the modules in another system, the way we tested then one set at the tested settings and If changing the timings makes the system stable that would suggest some other problem, like weak power or some other setting, or maybe that configuration will just not run 4 modules at those settings. But I would test the modules one at a time with http://www.memtest.org to be sure.

[deparist]

Thank you all who replied.

 

But guys, I didnt mentioned tha your prodocts are not working well. Did I?

I did not say that those memories dont match my mobo. Did I?

Besides, my mobo asus striker, hopefuly can handle almost all rams in the market.

 

All I said is Corsair says that this is the ram which has 4-4-4-12 timing as it is default. But it is definately not. It is totaly fake what it says on the package. It is just the ram which has the timing 5-5-5-18 instead 4-4-4-12.

It is not CL4 eighter. That is all the problem I have had with Corsair.

 

Meanwhile the store where I bought them, has already replaced with other which is my favorit, you know what I mean.

 

Sincerely yours.

 

 

Revision.

And I also would like you to be informed that my PSU is Tagan Easycon 700w.Armour full tower Zalman CNPS9700NT ;

INTEL Q6600 QUAD CORE, OS: xp64x pro which can address all 4 sticks

Your missing the whole point. Run it with one set, that is 2GB if you dont know, and you will get the 4-4-4-12 timings. It was stated twice, once by me, that those settings are for ONE SET, which again is 2GB. No where does Corsair say you can run 4GB, TWO SETS, at those timings. Maybe Im missing something here but the only problem I see is on your end, not Corsairs.

[Wired]

IIRC, last time I saw their packaging, it didn't say the timings were default, e.g. plug and play. That's what EPP and the like is for.

 

bigbuck08, what he's saying is that they don't default in the SPD to 4-4-4-12. IIRC, it's the same reasoning for why the 3200C2s didn't have their timings set in the SPD. They're the most popular, so they picked looser timings so they wouldn't need tweaking right off the bat to boot. Then, you can just set the timings.

 

The reverse of this is certain high end memory where the system won't run at those high speeds, so end users have to use slower memory to boot the system, set the timings, and then swap the high end sticks in.

[RAM GUY]

With the Striker board you can try the following settings to get 4x 6400C4 modules working at their tested settings:

 

Load Setup/Optimized Defaults

Memory Voltage: 2.1v

NB Core Voltage: 1.45v (this is technically overclocking the motherboard and must be done at your own risk)

SLI Ready: Disabled

FSB Memory Clock Mode: Unlinked

FSB QDR MHZ: Default/Auto

MEM DDR MHZ: 800MHZ (try 667MHz if you do not want to overclock the motherboard)

TCL: 4

TRCD: 4

TRP: 4

TRAS: 12

Command Per Clock: 2T

TRC: 28

 

None of our high performance DDR2 modules have their tested settings programmed as the SPD for exactly the reason Wired mentioned. You can check out the Data Sheet for the 6400C4DHX modules HERE, and you will see that the SPD is advertised as 5-5-5-18 at 1.8 volts, while the modules are tested to run at 4-4-4-12 at 2.1 volts. Also, the modules are tested in pairs, and we can not guarantee that they would run at their tested settings running 4-up in all motherboards due to limitations of different chipsets and CPUs.

My Friend,

I did not say that Corsair says nowhere that I cant run 4g two sets at those timing, but you do:-)

 

If Im not a ramguy as you are, how should I know that I cant.

 

It says 4-4-4-12 and I bought as it is. Thats it.

 

I m not sure if it is fair to publish following pictures in here, but if its not you can modify surely.

 

This is what it shows with corsair 4 sticks, cost 300usd tax included.

and another one which is installed from my other setup, and just 25 usd for each.

You tell me please, which one I should chose. And also beleive me I couldnt

realize the speed difference betwen two of a kind.

 

Here is the result what you said about 4 sticks together with my best regards.

We have already explained why the timings are set to a more relaxed setting please go back and read what was posted previously.

You can check out the Data Sheet for the 6400C4DHX modules HERE, and you will see that the SPD is advertised as 5-5-5-18 at 1.8 volts, while the modules are tested to run at 4-4-4-12 at 2.1 volts.

And you are compairing a DDR2-533 module to a DDR2-800 Cas 4 module for sure they will be much less expensive. If you are happy with them then by all means its your money and your system.

[Wired]

And you are compairing a DDR2-533 module to a DDR2-800 Cas 4 module

Heh, I was about to say that :)

 

Also, either your 4th stick is a different model than the other ones, or the SPD on it may be wrong. May want to contact the maker of that memory to ensure compatibility one way or the other.

[RAM GUY]

Not to mention our equivelent part is less than 32.00 USD right now doing a search for VS1GB533D2 modules. So he could have saved half what he paid for that memory and more than likely would have had better performance.

[deparist]

What ever you say here, wont change the truth about the fake which I've mainly mentioned from the beginning, guys:!:

[Wired]

There is no "fake", you are just perceiving the situation from a different POV. Ask this same question to any manufacturer and they'll tell you the same thing.

[java_ed]

:): I know what this argument is about.

 

Deparist thinks Corsair make some deceptive marketing with the timing.

Ramguy thinks Deparist has 2 pairs and therefore affect the timing.

I think it is just a miscommunication.

 

From my experience with 2 pairs on the eVga 680i board(similiar chipset as Deparist's Striker board), the EPP (the profile that is supposed to set the optimal settings for you automatically) simply doesn't work on the board bios (ver. P31) so the board uses the default timing of 5-5-5-18. In other words, the board will change any memory stick timing to 5-5-5-18 if it can't read its EPP properly. I changed it manually to 4-4-4-12 in bios and run it all the way up to DDR2-900 with the same timing.

 

Corsair guarantee the 4-4-4-12 timing at DDR2-800 on 1 pair. I got the same timing at DDR2-900 on 2 pairs so I am happy. ;): People getting DDR2-1000+ on this is going to call me silly... but I bet they can't get 2 pairs over 1000 ;):

 

I called eVga about this and they acknowledged that EPP has been a problem for some people. EPP is just a set of numbers your board is supposed to read from the memory automatically to adjust the timing. EPP to me, is a convenience tool which saves me the typing of 4-4-4-12. If my board can't read the numbers right, I 'll just type it in myself in a few seconds.

 

The truth is in the real testing which Deparist already proved it can run at 4-4-4-12 (in 2 pairs). He just thought the memory can run 4-4-4-12 because he "oced" it(since he consider tigtening the timing as ocing). Well, in this case, he is not really ocing but merely correcting the timing to the spec which the board itself couldn't set automatically through EPP.

 

If I were Deparist, I would report this as an EPP problem so Corsair can work with Nvidia in the future to correct this. If I remember correctly, Corsair is one of the first mfters to adapt EPP. So, glitches like this is expected for early models and it is no big deal either.

 

BTW, Deparist, if you can return those RAM, return them. You get it here in US at a fraction of cost. It hurts me to hear you pay so much for them.

[RAM GUY]

We actually developed EPP technology with Nvidia and AMD. And yes we were the first.

 

And I think that this is just an unrealistic expectation and not understanding the technology is what I see.
