Which Is The Best DDR2 RAM

Tags:
Last response: in Memory

Hi,

I m having Lenovo 3000 H-Series Desktop, Intel Core 2 Duo E4400 @ 2 Ghz processor. I bought this in the year 2007 and Lenovo provided only 512MB of RAM. Later on I upgraded it to 4GB of RAM with two stick of 2GB each in 2008 but brand and frequency was different,

1. 2GB Transcend PC2-5300 (333 MHz).

2. 2GB ZION PC2-6400 (400 MHz).

I was not aware tht one can not install 2 stick with different manufacturer and different frequencies till the time it started giving Me problem. I installed this in the year 2008 and now it started giving Me problem with the error like, BIOS error or upgrade your hardware etc etc and My PC was not booting. 1st I felt it must b some dangerous which My licenesed version of anti-virus failed to detect.

But My hardware engineered came and he checked he said its not a virus but its RAM which is giving a problem and he is surprised how come My PC worked till now.....

Taking into consideration this I want to replace this. So please advise Me on following questions,

1. which is the best, durable, fastest and highest frequency DDR2 RAM.

2. I m having 2 slots of RAM so please advise whether I should install 2 sticks of 2GB each or only 1 stick of 4GB.

Thanks In Advance.

A 2x2 gb kit is what you need. Stay away from off brands like you have now. Corsair, kingston, crucial, gskill, patriot, and samsung will all work well. You may use either pc5300 or pc6400, whichever is cheaper. You may also find some on craigslist. Ram is pretty durable, but can fail at any time. I try to use only ram with small heat spreaders which provide some protection when handling.

Lenova wants more info to link their specs. All I can say is if your motherboard has 4 ram slots, don't try running with just three sticks. Install whatever ram you have in pairs. The corsair should work fine if it's 1.8v which is the industry standard for ddr2; most newer boards have a limit of 2 gb per slot for ddr2.

Hi 01die,

Apologise for confusing You. I m having 02 slots only and at present it is running with those 2 generic RAMs. so just check with Corsair specification so that I can 02 sticks of corsair 02GB RAM.

Also check this link of GSKILL as well,

In GSKILL no where they hv mentioned whether it is having feature of heat spreader or not and alos it shows Error_Checking as Non-ECC now I don't wht it is.

Or You can suggest Me any specific brand to purchase 2 stick of 2GB DDR2 RAM which you feel is the best in DDR2.

thanks a lot for your kind and quick reply.

Based on ur reply I have selected Corsair's XMS2 — 2GB DDR2 Memory (CM2X2048-6400C5) XMS2 PC2-6400 (800 MHz) having XMA Heat Spreader and below is the link,

http://www.corsair.com/memory-by-product-family/xms-cla...

Request to go thru it and advise If I can go ahead and buy 2 stick of these to install in 2 slots to make it 04 GB or any other brand you can suggest.

tx.

The Corsair XMS RAM that you picked is great; very good feedback. I will be ordering 2x2 GB soon for my upgrade on one of my computers.

ECC RAM has error correction and is used for servers; not normally for desktops. For our desktop use, non-ECC is recommended.

Tighter timings are usually better and faster. As o1die stated, stay with known brands; and Gskill (and Corsair) are good brands.

A couple of things that you should pay attention are, 1) the RAM frequency, and 2) the RAM voltage.

From the motherboard user's manual you can find out the max supported RAM frequency; do not get RAM with greater frequencies than what the motherboard will handle.

1.8 V should be fine for DDR2.

Coming back to the RAM you listed, make sure that it is compatible with the rated motherboard RAM frequency. One other thing I check is to ensure that the RAM is on the motherboard's AVL (Approved Vendor List). Most major brands will meet this requirement.

I am expecting to buy my Corsair RAM (XMS) on Black Friday.

I m having Lenovo Intel Core 2 Duo PC but don't hv any manual :cry:  IF u want more details of other specification which can help u in finding mobo part then can give u tht.

Anyway final verdict from u which one u suggest, Corsair or Gskill and if Gskill then which memory from GSKILL. Actually, frankly speaking higher number from GSKILL is attractng Me but still suggest Me the RAM and I will go for it.

Also want to knw r u from India if yes, then from which state and city.

Tx a lot.

For my computer, I am buying Corsair XMS RAM; the one you chose initially. Gskill is just as good. It's just that I am a Corsair fan; Corsair PSUs and Corsair RAM.

My avatar is a picture I took during a 11-week tour of 22 major cities in India. I am from Chicago.

Gr8 Ubrales. Then I will go for Corsair's XMS2 — 2GB DDR2 Memory (CM2X2048-6400C5) XMS2 PC2-6400 (800 MHz) having XMA Heat Spreader. Purpose for which I asked tht is I m having Logitech Z2300 speaker system and I m facing problem with sub woofer so felt if someone is from India then can take help from him.

My next upgradation is Corsair PSU HX 650W.

Tx a lot 4 ur kind guidance Ubrales :bounce:

Wow! The Corsair HX series is modular and superb!

I have the HX850 in my present computer and I love the ease of cable management in modular PSUs.

Here in the US, we kick off the holidays shopping season the day after Thanksgiving Day, and it is known as Black Friday. Black Friday because the accounting books go from the red into the black; hence the term. This year it is on November 25th. and that is when I will order my Corsair XMS RAM.
