ASUS UX32VD replacement ram

What should I use to replace the 2GB ram that comes with the Asus. It needs to be C11 (can't use Corsair Vengeance even though it fits perfectly b/c it will be downclocked) and be similar in specifications to the Corsair Vengeance b/c as seen before it fits perfectly.

I was looking at the Kingston Value Ram, but it's product dimensions are quite different and I'm worried it won't fit same with a Patriot Memory Signature.

Which is better if they do fit? Kingston or Patriot?

Thanks!

 

Its a shame about the Corsair, as that would have been MY first choice. I have absolutely no experience with Patriot memory but i can 100% vouch for Kingston. To date non op my Kingston product have failed me. Just my two cents.

 

I bought and installed this one. It fit just fine and seems to be working flawlessly. I get a WEI score of 7.3 on the RAM. I have used Patriot memory many times in the past and have no qualms in recommending it.

Patriot Memory Signature DDR3 8GB 1600MHz SODIMM (PC3 12800) PSD38G16002S

Amazon.com: Patriot Memory Signature DDR3 8GB 1600MHz SODIMM (PC3 12800) PSD38G16002S: Computers & Accessories

 

That's what I just ordered a couple days ago from ncix. Havent even got the laptop or ram in the mail yet. I got the Corsair Vengeance CMSX8GX3M1A1600C10 8GB because thats what alot of people are recommending online.

Now after reading more online I see it wont run as good as it should. Its only CL10. I didnt know it made a difference

Too late to cancel since its already been shipped. Guess I'll have to return it and find something else.

Any other ram you guys would recommend? Amazon wont ship ram to my house in Canada

 

Actually, the lower the CL the better... Keep the Corsair, it's a good SODIMM card.

 

Really, it will be better even tho its going to drop it down to 1333mhz?

 

I hope the posters dont think me rude. Is there a positive answer to this query? Is the Corsair suitable or not. Need to know as I have the 8GB in the post.
As one may read some posters say the Corsair is fine, some says its not and some say its even better? I am totaly lost. Lot of money to lay out IF the Corsair is the incorrect type.

Is there a poster who actually knows THE answer lol

Kindest regards.

RAM is organized in cells (like an excel worksheet).
CL - stands for CAS (Column Address Strobe) latency - it is the time between the memory controller asking the memory module for data from a particular column, AND the memory module sending the data back on its output pins. And this value is for a transaction. Most of the time data is read in burst mode, hence this lag is only for the first bit of data to be sent. There would be no delay for all the subsequent bits in the transaction.

One more thing to notes it that CL is expressed in clock cycles.

And if you've checked newegg for the CAS latencies available at different DDR timings - you'll notice that as the DDR clock gets higher, even the best and expensive RAM modules have higher CL values. But you need to understand the fact that in terms of the actual time it takes, the higher the clock - lower the time per cycle. This should explain why a CL9 DDR1600 is slightly faster than a CL7 DDR1333.

And in terms of difference between CL10 DDR1600 and CL11 DDR1600 - trust me less than .01% of any of that difference can be seen in real-time applications. Do not go by synthetic benchmarks - those just represent mere numbers. Like for example a difference between a 160 bhp vs 180 bhp car engine."

Just read this from the Crucial site;

"

8GB
DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V • 1024Meg x 64 • • Part #: CT3340957."

Clearly states CL11. Problem is I have no idea what the difference is. I have seen a number of youtube videos where the Corsair has been used that is where I got the idea from in the first place.
Being a novice I must write this is a steep learning curve filled with its own jargon and pitfalls around every bloomin corner.

Further ivestigtion.

"Column Address Strobe (CAS) latency, or CL, is the delay time between the moment a memory controller tells the memory module to access a particular memory column on a RAM memory module, and the moment the data from given array location is available on the module's output pins. In general, the lower the CAS latency, the better. In asynchronous DRAM, the interval is specified in nanoseconds. In synchronous DRAM, the interval is specified in clock cycles. Because the latency is dependent upon a number of clock ticks instead of an arbitrary time, the actual time for an SDRAM module to respond to a CAS event might vary between uses of the same module if the clock rate differs."

I am now totaly confused.

 

Yes, lower CAS values are better, so CAS 10 is better than CAS 11 (given we are talking about the same frequency, this is important as you'll see later). The problem is that when you have multiple memory sticks, all memory sticks have to run at the same frequency and with the same CAS value. So the problem seems to be that the 2GB that is soldered on the motherboard runs at 1600 MHz and has CAS 11. Now, when you add a second stick, BIOS has to figure out what is supported frequency/CAS combination for both sticks.

If you add 1600 MHz CAS 10 stick, BIOS will look at the frequency values of the sticks. Since both are 1600 this is fine, it proceeds looking at the CAS values. New stick is 10, the soldered one is 11. Since soldered one does not support 1600MHz at CAS 10, it will be "downgraded" to 1333MHz to be able to run at CAS 10 (as you discovered during your investigation: slower frequencies - lower CAS latency possible, higher frequency - higher CAS). Okay, now both sticks run at CAS 10, but now the soldered one runs at 1333MHz, and the added one at 1600MHz. To make them compatible, BIOS will "downgrade" the added memory stick to 1333MHz. Now both sticks are at the same frequency/CAS values (1333MHz/10) and BIOS is happy. But you shouldn't, since 1600/11 should be slightly faster than 1333/10. This is why 1600/11 stick is recommended (it allows the laptop to run both your sticks at 1600/11), while if you add 1600/10 (even though in itself it is better), it will force BIOS to run the memory channel with two sticks at 1333/10.

 

I put this in my UX32VD and it runs at 1600mhz dual channel:

Thank you for the most excellent reply. It is members like you who give true value to a forum.

I shall return the Corsiar and have now ordered this ; KINGSTON 8GB DDR3 1600MHz Non-ECC Reg CL11 SODIMM. I hope this is now the correct RAM.

Thank you again,

regards,

Ryland

 

So this Kingston memory is good then?

This looks like the same thing I think.
Kingston KVR16S11/8 8GB 1600MHz DDR3 Non-ECC CL11 SODIMM - Kingston - KVR16S11/8

The Corsair ram I bought at ncix so I think if I return it I will get a credit. So I need to buy the new ram there too.

 

Hi,

I am a consumer, I understand the Kingston is a duplicate specification. PLEASE understand I am also a mushroom in such matters.

Ryland

 

Hi, I suggest to buy the mushkin 8gb memory or the crucial one that you can find and order directly from the producer web site.
The kingston memory is not exactly the best choice because works at 1,5 volts instead of 1,35 like the mushkin and the crucial and the memory on the motherboard.
At the moment in the USA the crucial's memories from the online store ar finished, you can just buy it from the UE store.

 

It can't run in dual channel because it has to be the same size (i.e. another 2gb).

 

Not exactly correct. The first 4GB of memory will run in dual channel mode, thanks to Intel's flex memory technology (and i7-3517U does support flex memory, look at the bottom of the table).

If you do not exceed 4GB memory usage, it will run at the same speed as with 2 2GB sticks. If you do exceed, then single-channel memory access to memory over 4GB is still orders of magnitude faster than hdd/ssd-based page file (which would be used if you exceed 4GB with 2 2GB sticks) as single-channel memory is not all that slower than dual-channel mode in the first place

 

This is the correct answer. CAS 11 for the best possible performance even though it seems counter intuitive.

 

I purchased the Kingston KVR16S11/8 8GB 1600MHz DDR3 Non-ECC CL11 SODIMM from newegg.com for $37.49 shipping and tax included ( Newegg.com - Kingston 8GB 204-Pin DDR3 SO-DIMM DDR3 1600 Laptop Memory Model KVR16S11/8
It came in yesterday. I installed it and voila - I have now 10GB of RAM... Works beautifully and fast.

 

I will put my experience here and hope someone can help with my problem:

I have the UX32VD-R4002V dated Aug 2012 and tried to put in the above Corsair CMSX8GX3M1A1600C10 8GB RAM, which I ordered based from Amazon after reading this forum for which stick to buy. Unfortunately, with the Corsair RAM in the SO-DIMM slot my computer will not boot! It cannot even reach the BIOS. However, the computer boots normally after I put back the 2GB stick that came originally with the computer.

Can anyone suggest the issue?
(1) Is CMSX8GX3M1A1600C10 completely incompatible with the 32VD?
(2) Would this happen if the memory stick faulty? The fact I bought off a very reputable seller on Amazon lowers this chance but I don't rule it out entirely. ATM I have no way of testing.
(3) There is something else I need to do before replacing the RAM?

Thank you if you can help!

 

Hey mykie - looking at your signature, I'm about to follow the exact upgrade path you did. Just curious, what did you do for the SSD installation? A clean windows install or a drive image?

If windows, did you hit any issues with the USB 3.0 drivers?

Thanks!

 

Hi,
I have the same problem with kingston, have you received any answer in the meantime ?

 

Thank you for this excellent and accurate information!
I placed my order for a UX32VD and Mushkin Enhanced Essentials 8GB 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model 992038 and a 256GB Samsung SSD.
