Sodimm ram differences

Hi guys, I own a HP laptop with 4GB ddr3 SODIMM ram, and I want to upgrade it's RAM, after reading the manual I figured out that I can upgrade up to 16GB (2x8GB) 1333Mhz.

After a small research all I could find was Kingston, Mushkin, Corsair, Crucial.
Is there any difference between them?Should I just pick the cheapest one?
(Below you can see links of these RAMs)
Please ignore the prices,since I live in Greece and I can't buy from amazon.com
Thank you

Hi and welcome to NBR!

That depends on what you want to do with your RAM.
- but Kingston and Corsair and Crucial are the most recommended. Haven't tried Mushkin RAM ever but I guess they are alright, so basically the cheapest out of the 4

good luck!

 

I have two Mushkin sticks in my laptop, absolutely no problems. RAM is RAM is RAM.

 

Thank you for your fast reply guys, I was just wondering if every brand has its own specification, like some kind of latency or something...but I guess they are all the same...
Thank you once again.

 

Even if you happen to mismatch CAS latencies or speeds, the RAM will still work, just at the lowest common denominator. For example, if you buy 1066MHz RAM (I'd aim for 1333MHz) and install it and keep your current 1333MHz RAM stick, both will run at 1066MHz.

As for CAS, it doesn't really matter that much anyway. DDR3 is fast enough to where all DDR3 RAM pretty much feels the same, and benchmark basically the same scores, plus or minus a few percent points. Pretty much the only reason to consider RAM higher than 1600MHz is if you happened to have a notebook with an AMD APU, to speed up the integrated graphics.

 

I was aware of that, that's why I'm planning to buy a set of 2 RAMs 1333mhz.

Thx again. I'm really impressed with this forum.Realy fast and good replies. Well done!

 

Buy low voltage RAM, system will run cooler and I think battery time also longer. The 16GB 1.35V Crucial looks good from Amazon!

 

RAM in itself barely takes up any energy from the battery... we're talking about maybe a few minutes extra, at most. If you're concerned about battery life, dim your display a bit and/or change your Windows power settings: either will have a much bigger effect on battery life than the type of RAM you use.

 

Forget about low voltage RAM (unless your system fully supports it).

Why limit yourself to PC3-10700 spec's?

Buy the cheapest, fastest, biggest capacity RAM SoDIMMs for the biggest performance and responsiveness upgrade for your system with a full return policy (no restocking fee) and lifetime warranty too.

If you buy PC3-12800 SoDIMMs; even if your system cannot use the higher speed, it should still be noticeably more responsive (read the link I provided).

Good luck.

 

wow...that's really interesting...I own an i7 2630qm...
but I have a question...does the maximum RAM speed my pc can handle depend only on my CPU? what if my modo wont support it?

 

Keep reading the thread... even on low end setups with nowhere near the ability to handle the SoDIMMs installed (at least, no able to handle them at their rated speed), the system was still noticeably more responsive (and well worth the less than $5 difference for the 'better' RAM).

 

true!the price is almost the same...I am definitely going for the 1600mhz!thnx man!

 

The low voltage RAM delivers more than half hour extra battery time in my low power consumption system, the bottom of laptop also cooler with few Celsius. All modern laptops are support at least 1333MHz 1.35V RAM, the most moderns are fully supports at 1600MHz level.

 

I can believe that low voltage RAM provides more than a few minutes of extra battery time.

Of course, it's hard to provide all of the details on the spur of the moment. Which is what I think that both Tiller and Kuroi-Tsubasa were attempting to do.

So I'll take a shot at doing that, adding my 2 cents on top of their comments and your comments.

My own new Lenovo T530 will show up by next Friday (hopefully). My plan is to use it as is for a week and then get down to modifying it as I want it to be.

That includes pulling out the 500GB HDD (that only cost me an extra $20 over the smaller 320GB HDD, and I can use the 500GB HDD for backup after my 1 year warranty runs out whereas I can't do that with the smaller 320GB default HDD) and setting it aside.

I'll then put a 512GB M4 SSD (9.5mm thick) into the main bay and do a fresh install of Win7-64 Pro w/SP1, since I bought the T530 with a legitimate Win7-64 Pro ID. Meaning that one can find the 3GB .iso file for Win7-64 Pro w/SP1 on the web and create your own free bootable DVD from it. It's the ID that you pay money for.

Back on track to the memory thing, after I get the SSD set up, and am able to do full backups (via clonezilla) to a temp HDD that is plugged into the ODD bay (assuming that that can be made to work), the next thing will be to buy 16GB of memory (2x8GB sticks) that is top speed rated at DDR3 1600 (PC3 12800).

It's easy to find 1.5V memory like this at newegg (which permits you to zero in on the search specifics of what you want), at current USA dollar amount of $65-$80 for a pair of 2x8GB sticks of laptop memory.

Sales seem to not be all that great this Xmas, and now that there is some serious chance of this whole "fiscal cliff" thing going past January 1, 2013, I kinda suspect I'll be able to get 2 sticks of DDR3 1600 (PC3 12800) rated at 1.35V for roughly $80 in just another month or two.
