Asus P5E3 PRO - 775 - X48 / not listed ?

[paradogz]

Hello everybody,

 

Thanks for your learn & explore tool, i found the exact RAM modules I am looking for.

 

 

But, the new P5E3 Pro = http://www.asus.com/Motherboard/P5E3_PRO/#specifications

 

Is a X48 chipset, not x38 like the Corsair Tool says ? The one listed on the tool is a "P5E3 WS Pro", whereas mine is just "P5E3 PRO" and is definitely X48.

 

So, as it's a really important decision, I just want to make sure that theses two models :

CMP8GX3M4A1333C9

cmx8gx3m4b1333c9

 

Will be 100% compatible with my board, and if not what is model I should get, giving the fact that this board is DDR3 1600 compliant, and I'll be more than happy to get the DDR3 1600 sticks.

 

Thank you very much for your help

Unfortunately no, Corsair would not have any modules made at this time that would be compatible with that MB. The x48 chipset has a limitation of modules that are constructed from 256mb each max. Anything Corsair makes now would be made with 512mb IC and would no be usable in that system.

Hi,

 

Your answer is rather technical and I am not a specialist regarding RAM technology.

 

Do you mean that what is produced at the moment will not be suitable for my motherboard, but that I'd be able to find "old" corsair compatibles with my motherboard ?

 

Thank you for your answer.

[paradogz]

After a few research, it is said that these models would be compatible with my MB. They are on amazon for 45£

 

CMZ8GX3M2A1600C9 (4go x 2) /// Can someone explain the difference with CMP8GX3M4A1333C9 ?

CMP8GX3M2A1600C8 (CL8) (4go x 2)

 

Can anybody would be very kind to confirm this ?

Correct, unless you could find old stock somewhere any thing that is made today would not work on your MB. Most places like Amazon would not have old stock and would not let you specify an older version number.

CMZ is Vengeance series...CMPis Dominator series and the only difference between the two CMP set would be speed. 1333mhz or 1600mhz. And with your CPU you are limited to 1333mhz so the Vengeance and 1600mhz kits would not be compatible. And again as I stated earlier, any of those kits would no longer work in that MB. because of the chips used to make the modules.

 

If you want to wait for RamGuy to confirm this before you buy them that would be fine .

[paradogz]

Thank you for your answer.

 

If that is not too much asking and that I am obvioulsy, cluesless about those "little things" that makes a HUGE difference, would you or ram guy would be able to provide me part number that I can look up for my MB ?

 

Regarding the 1600, I just want to double check with you if this MB is not "an exception" for it is sayed that these kind of RAM (1600) would be compatible ( Source : http://fr.asus.com/Motherboards/Intel_Socket_775/P5E3_PRO/#specifications ),Also some 1600 RAM are also present in the QVL list. ( Source http://dlcdnet.asus.com/pub/ASUS/mb/socket775/P5E3_Pro/P5E3_PRO-QVL.zip )

 

So basically, what would make my day is a Part Number of a Corsair DDR3 1600, CL8, 2 x 4Go, that I can look up on the net !

 

Thank you very much for your help, again. :idea:

It has nothing to do with the Mb but everything to do with your CPU. You cant run memory faster than the wha is called the front side buss in your CPU. And that would be limited to 1333mhz. Your MB supports speeds of up to 1600mhz to allow for overclocking. Which I'm sure your not doing.

Like i said I'm sorry, but there are no kits that would be compatible with that MB as of now. Corsair is just not making memory modules constructed of 256mb chips. which is what you would need with that MB. With an aging system such as yours, your going to have a hard time finding memory that would work with it.

[paradogz]

Oddly enough, I do OC, i'm on a 9650 (Stepping E0) @ 3,6 Ghz 400*9 , 1600 FSB @ Stock Voltage. Really easy to achieve as there was a lot of tuto to tell you how to do it.

 

What I'm asking peanutz is an OLD corsair module that i could look for, for example, the very first DDR3 1600 CL8 models that came up, internet is a very small villeage and find that it's quite easy to find stuff you really need. I do understand there is no manufactured DD3 that is compliant at the moment, what I'm asking is for an old one for there is DDR3 1600 in the QVL list, i just need a 4 x 2 GO CL8 / 9 part number, when this MOBO was realised.

in the QVL from Asus, for my MB (P5E3 PRO)

 

CM3X2048-1600C9DHK is a DDR3 compliant, 1600 MHZ

Also CM3X2G1600C9DHX

 

So obviously, and it's quite contradictory with what you've said, there WAS compatible Corsair DDR3 1600 tested and validated for this model.

 

Finally, what I'm after is the very same modules, but in the 4Go x 2 version and possibly with a CL8, using the same technology; It does not matter if they are not produced or if you think I am going to struggle, I am an internet scavenger ;)

 

Hopefully I've made sense.

 

Thank you for your help.

No, I never said they were not produced at one time. Just that when ordering memory you cant or usually cant specify what version number which corelates to the size of the chips used to make the modules.

 

So if ASUS QVL specifies a version number then they would HAVE to be that version.

As far as giving you a list of modules that would be compatible with an older version number I can't do that.

You can however look for the memory and check the version number against this chart to see what size chips were used

http://forum.corsair.com/forums/showthread.php?t=68811

 

As long as they use 256mb or less chips to make the modules then it should be fine.

Ok, I was convinced you were saying the opposite, my bad.

 

So if ASUS VL specifies a version number then they would HAVE to be that version.

 

As far as I'm concerned, I found this list really erratic and they do not really bother trying different RAM.

My problem I'm looking for older models, the informations regarding these old modules will be really hard to find, that is exactly why I came here in the first place to ask directly from Corsair if they can look up this information for me, if it is not too much asking.

 

 

from different topics, especially a french one, I found a guy claiming he managed to get 4x 2Go 1600 DDR 3, without telling the exact model unfortunately. This is exactly what I'm looking for here.

 

Any model of Corsair DDR3 1600 CL8 (or 9), 4Go x 2, that could be compatible with my Motherboard P53 PRO x48 ? thanks a lot

[RAM GUY]

At this time all of our DDR3 modules are made with 512m X 8 memory IC's which would not be compatible with the Chipset used on the ASUS P53 PRO x48.

I would save your money and put it towards a newer MB using a Core I5 or I7 CPU then you will be able to use most of our current modules.

[paradogz]

Hello Ram Guy, I did understand that there is no RAM module at the moment (as in being produced) because Peanutz said it.

 

Giving the fact :

 

• My P5E3 PRO is compliant DDR 3 1600

• There is CORSAIR DDR3 1600 in the QVL list but not the capacity I want

• I dont necessarily want a brand new product and can easily get it from Ebay/GumTree/Craiglist...

 

Can anyone would be able to give me the reference of the OLD DDR3 1600, possibly 4Go x 2 / CL8 or 9.

 

If not no problem, i'll ask somewhere else. cheers ;):

 

PS : I already got the motherboard.

[peanutz94]

Really the easiest way in your case would be to look for some of the modules listed in the QVL and then see what version they are and check them against that DDR3 chart.

 

What your asking for is a lot harder to provide than what you would think.

 

Just for instance if you take the modules I have which are a version 5.11 which would actually be what your looking for. Version 5.11 would be 256x8IC's . But if they were just a 5.1version those would be 512MMBx8 IC and would not work with your MB

 

Look for older sets of Domionator or XMS3 modules would be your best bet. Any DDR3 modules as long as they are made with those specific or less IC's would work

 

 

I did download the QVL list from ASUS and they only list three sets of Corsair modules but list no version number. But there would actually be many more kits that would still be just as good and function just as well but have not been tested with that MB

[paradogz]

Right, I have 2 people having this MOBO saying that, if the XMP and proper voltage are applied, CMZ8GX3M4X1600C9 4 Go x 2 is fully stable (memtest + solid rock desktop / gaming utilisation).

 

I have a premium account on amazon allowing me to return things in 30 days, so I'll be able to test them and leave the feedback on this thread, and then send them back in case of problems.

 

Regards.

That MB was before XMP so I'm not sure what they are talking about there. I guess all you can do is try it, but i really don't think they will work.

[paradogz]

Let's see for science.

[paradogz]

Still waiting for my Corsair RAM.

 

Meanwhile, borrowed DDR 3 1333 Mhz (Other brand, won't mention it) from a friend. 4 Go x 2, of new DDR 3, their latest model.

 

The kit is 4 Go x 2, 1333 Mhz. You said 512 chips IC's wouldn't work, well it works like a charm, on my stock voltage OC + manual timing and voltage, i'm more than happy to say that it's rock stable.

 

Also, Peanutz, you said there wouldn't be XMP, however there is, I will get you a screen shot of my BIOS asap.

 

I had to update my BIOS otherwise it wouldn't post (a bit of a heart failure at this point tbh)

Will keep you posted on Corsair performance. Suppose to get 1600 Mhz, remember ;)

 

Sorry for asking the same question over and over again regarding the Corsair reference, but I do think, based on everything I have seen on the internet and from my own experience, that this "X48 775 socket" has its own secrets regarding DDR3 Ram.

 

You guys should keep a close watch on my future posts.

How many chips are on the module?

[paradogz]

Here you go, so that is 256mb chips, I assume. This a really easy to find model and still being sold on amazon.co.uk .

 

I find hard to believe that Corsair can't find the equivalent model for me, whereas a competitor still sell these, but hey, it's 2013, it's bad luck maybe.

I am sorry but I would need to see both sides of the modules and the label before I could confirm it would be compatible. And I am sorry but you have a MB that is more than 6 Years old in design so we are not making memory for past products only current products.

The way you can tell by looking at the module is with a little math if its a 4.0 Gig module and there are only 8 IC's on the module that would be made with 512M X 8 IC's IE 512 x 8 = 4096, so you want a module that has 16 IC's IE 256M X 8 = 4096.
