Ram, which is better performance wise.. and why?

For my new m15x im deciding between Corsair or Kingston ram modules. 2 2gb sticks.

Any opionions on which company is better to go with? and why?

 

The cheaper one.

 

Lithus is right, if you are not going to be tweaking memory timings to get more performance

if you are intending to clock memory as fast as it goes (providing the laptop will let you)

then the ram with the lowest cas latency etc will be best

but if you are just upgrading and leaving it be, the cheapest should do

 

Well the 22nd is allmost here, and ill have my student loan im going for the x9000 so I do indeed plan on tweaking. I dont have much knowledge when it comes to ram tweaking though, so with this in mind. which company or perhaps a better company?

 

well I dont know if software overclocking will work especially with vista
but the bios appears to have a lot of options locked out by AW

of course the bios is where you would normally set the RAM timings, there are tons of topics on the web with how-to's etc

 

Well quite a few of my gaming budies recomend corsair, but honestly I havent really heard much of them... hmm

So which brand really is better, taking out the cost as no matter.

 

there are several software for vista that can help set up overclocking on your new laptop

everest ultimate is a great one, but as said, many option can be configured in the bios w/out software

i see corsair rec a lot, but i would try the cheapest unless there is a specific reason as mentioned to go with the other

hopefully, someone who is very experienced in oc will give you some recommendations....

 

if cost is not option look into corsair extreme modules (dont know what they do for laptops) also there are many other brands, have a look at GEIL , OCZ and crucial

many of them do lots of ram for desktop pc's that have lots of o/c potential, I dont think they market too much for notebooks but it can't hurt to look

at the very least get ram that has heatsinks on it

Q: I have 4GB of RAM but I am seeing only 3GB in Windows, why? What can I do to fix this?
A: Users reporting only 2.75GB~3.5GB being seen in Windows is an isolated, well-documented problem within 32-bit operating systems. This is due to Windows reserving and allocating a portion of your installed physical memory for hardware mapping and that portion of the memory will always remain inaccessible. Fully detailed reference can be found here http://support.microsoft.com/kb/929605/en-us. There is no guaranteed fix for this problem and chances are you will never see anything close to 4GB. However, there are a couple of methods that MIGHT configure Windows to address full 4096MB of your physical memory but the portion that's being reserved for hardware mapping will remain that way. Note that you must first enable the "Memory Remap" feature in your BIOS. If it's not available it means your motherboard's chipset does not support 4GB RAM addressing even if the motherboard can detect up to 8GB or more. *Disclaimer*: This information is being provided on our website for educational and referencing purposes only. The end result will depend on your chipset/BIOS and how well you have followed through the steps. In no way, under any circumstances, will GeIL and its staffs/affiliates be held responsible for what you do with this information. You are strongly advised to perform more research on this topic before utilizing the information provided herein. Currently, this is only available to Vista users. Method 1. - Enable PAE Mode ( Physical Address Extension) This method modifies Vista's system core to use 3 memory addressing cycles instead of 2 by default and it's theoretically slower, so you should disable this if you ever go back to a lower amount of RAM. *a. Start>All Programs>Accessories>cmd, right-click on it and choose "Run as Administrator" to open up an elevated Command Prompt. *b. Type this command: BCDedit /set PAE forceenable *c. Hit enter, and you should see this message: "The operation has completed successfully". If you see this, exit CMD and reboot your computer. If you don't see any change in RAM amount under Windows, you can try the second method below. Method 2. -Disable DEP Mode. (Data Execution Prevention) DEP allows Windows Vista to reserve a portion of your physical memory to monitor memory and kernel level data executions. If Windows thinks a certain program you're running is malicious, it will utilize DEP and prevent the program from being executed at all. This is a security feature to help protect your computer from mal-ware attacks and it is strongly recommended to be left untouched. But if you must free up as much memory as possible, then you may try this method but do this at your own risk. *a. Start>All Programs>Accessories>cmd, right-click on it and choose "Run as Administrator" to open up an elevated Command Prompt. *b. Type this command: BCDedit /set nx AlwaysOff *c. Hit enter, exit out of CMD then reboot computer. To turn DEP back on type the following command in CMD: BCDedit /set nx AlwaysOn

 

Take the cheapest one that offers the lowest CAS (at 667 Mhz).

 

Doing some research right now between, Corsair, Geil and Kingston.

 

I used to do some overclocking of my dekstop rig and back then what RAM you got depended heavily on your CPU brand. Now, I can't for the life of me remember exactly what it was but it was something along the lines of Kingston being better for Intel and Corsair being better for AMD. If I wasn't currently sitting on a horribly slow internet connection I'd look it up for you but maybe you'll have some luck googleing it.

 

Try and understand there is no performance difference. Besides the speed the only thing that matters is the CAS. Get one with a low CAS (preferably 4).
The brand doesn't matter, the actual memory chips do. However, by reading some benchmarks you'll see that there is no real performance difference.

 

This is the ram I have been looking at, but it doesent say what the CAS is... Though it does have heatsink spreaders.

Go to NewEgg and see what's what. The heatsink thing doesn't help performance.
