Laptop came preinstalled with "ELPIDA" RAM. Change it?

[Synomenon]

My laptop came with "ELPIDA" branded RAM which I've never heard of. There are two 2GB PC2-6400 sticks.

The sticker on each says this:
ELPIDA
2GB 2Rx8 PC2-6400S-666

Before purchasing the laptop, I purchased a kit of Corsair RAM. The Corsair RAM was meant to go into a different laptop I intended to purchase (but didn't because it was discontinued). The Corsair kit is also 4GB total (two 2GB sticks). The RAM comes from Corsair's value line and it's also DDR2. The package says "DDR2 - 800MHz". I think that's the same thing as PC2-6400.

Should I remove the stock "ELPIDA" RAM and replace them with the Corsair RAM?

Elpida is a major memory manufacturer and was created by the merger of Hitachi and NEC DRAM businesses. Unlike Corsair, that only assembles memory modules using various makes of memory chips, Elpida builds the memory chips, too.

Oh ok. So is it not worth switching out the stock Elpida RAM with the Corsair value RAM?

 

[taltamir]

Elpida is a company that makes actual ram physical chips. It is one of the only 4 companies in the world that do that.

Certain corsair models use elipda chips.

To make a video card analogy, elpida is like AMD or nVidia... Corsair is like XFX or BFG.

Thanks guys. I guess I'll just sell that Corsair RAM then. No point in replacing the stock Elpida RAM if the Corsair kit might consist of Elpida chips as well.

yeh if your mobo supported it maybe go to CL4 ram but the improvement probably would be minimal on a lappy

The only benefit you'd see (& you'd see it only in synthetic benches) would be if the Corsair RAM has lower timings like 4-4-4 or 5-5-5 instead of the 6-6-6 the Elpida has.

As has already been explained, Elpida actually makes the RAM chips, unlike Corsair, who is just a brand who assembles RAM (often using Elpida chips).

Some of the best desktop DDR2 is made by Elpida actually, like a kit i own.

i got two 4gig kits of the ocz platinum low voltage (sequential s/n's too!), but mine is the pc2 8500 version (ddr2 1066), and they use the elpida chips as well. they are also the same ones that go in the ddr2 1200 viper series.

imo it would not be worth swapping and by getting rid of it you can put that cash towards a ssd if you want that laptop to really fly, and get better battery life to boot.

ELPIDA has some damn good chips out there. Aren't BBSE's still sought after on desktops? They also made some amazing CL6 DDR-1600 chips (half of which were probably defective... but if you got in on a good set, wow.... it's like the BH-5 of today).

Dunno how their lower end RAm performs though

i've seen a move to elpida in oem hp systems lately

Ok so my laptop has been acting funny for the past couple of days. So I decided to run Memtest86+ (v4.10) on it last night. When I got up this morning, it showed one error from the first pass.

Turned the laptop off and left it for a couple of hours. After that couple of hours, I turned it on again and tried running Memtest86+ again. This time after only 14 minutes it showed 22 errors.

I turned the laptop off again and picked it up. The underside was scorching hot. I waited again for a couple of hours then put it on one of those cooling pads to help it cool down while trying Memtest86+ again. Memtest86+ is currently running and has been now for an hour and a half with no errors so far.

Could the errors from earlier have been caused by too much heat?

Edit: Starting a new thread regarding this.

define scorching. the mini-9 gets warm with 2gb of ram. warm as in wow that is warm but my ballz are not bothered. imo that is too warm. the temp sensors on the 6 channels of ram ( times 3) on my server is damn near ambient even at full load. 72gb of ram. perhaps your cooling system needs some cleaning man.

i've seen
1. crap silver paste on heat pumps
2. tons of dust/hair/lint in the fans
3. blocked air ports with who knows what (nasty!)

laptops are more critical than servers because they are not allowed the room/noise/power to move monstrous volumes of air so every little bit counts.

and obviously 8gb is going to consume more power than the same ram 2gb so you may have increased power output. probably why they make low voltage 1.35 ddr3 and standard 1.5 ddr3 now.

Scorching as in gets uncomfortable to touch after a few seconds. The laptop is fairly new (around 4 months) so I don't think its cooling system is clogged with dust just yet.

Memtest86+ has been running now for a little over two hours with no errors. The laptop is still on the cooling pad.

I think I'll let it sit overnight again.
