Hello,

I'm looking for memory for my future system upgrade, and have a chance to buy 2GB of Corsair XMS2 6400C4 memory for quite a cheap price (hopefully around $100- 110). But both on NewEgg and here I read reports of several people having had problems with those, so I wanted to ask whether you think it's a good choice or I might better buy some other sticks (which if so?).

Thanks!

You should list your complete specs so someone can make specific suggestions for you. Corsair is a maker of some of the most highly regarded high performance RAM out there. I have 5 GBs of this PC6400 CAS 4 G. Skill and use it with a P5B-Deluxe and a q6600. The customer reviews are high and deservedly so.

Thanks. The supposed system will be something like this:

Intel Core 2 Duo e4300 (great overclockability and allows me to save some money for a good m/b and video card)

Asus M/b (trying for P5N32-SLI)

Asus nVidia 8800 GTS 320 MB

etc.

Edit: just read the reviews for the G. Skill. Is the difference between Micron and Promos chips really as crucial as it seems? In that case the Corsairs are probably not the best choice, since as I understand they switched to Promos for the 6400C4 kits.

The sixth customer review from the top says:

Thats only true about their extremely high-end products that have a very poor price/performance ratio.

The truth is that Corsair and OCZ are not worth ur money. They use inferior chips and price them above their competitor's superior chips.

Look for companies like Geil, Crucial and G.Skill for the best products at the best price. The truth is that Corsair and OCZ not only price their products very high, but also dont make good high-end products at all.

These two are both the best, buy one of them:

They use far superior chips than the Cosair 6400C4 and are price at almost half the price. There is no question here who is best.

Thanks a lot, guys!

You mean that's not true as far as you are concerned. I've used Corsair value RAM and Corsair XMS. I would consider Corsair products to be of high quality and Corsair high performance RAM to be one of the more highly praised, more sought after and most often used where professional high performance system benchmarking is involved. I really believe if you had a bad experience with Greyhound you would tell me the company is known for their poor price/performance ratio.

The crucial you listed are very good but the G-Skill are a hit and a miss
Some modules are Elpida AG-6E-E (before 05/2006) some are microns
Corsair modules are for the most very reliable and you get what you pay for.
My preferences are Corsair XMS2 Super talent or Crucial (anything)
If you want price / performance go for the Corsair value ram 2 GHz package under $90.00 slap heat spreaders on them and clock 800MHz all at low voltages CAS5

No, I mean its simply not true.
This isnt a subjective experience, but an objective look at their memory, wich is mostly NOT "high-quality" and definetely not high performance.

Im of course talking about the high-end - the one that most ppl who want to overclock are looking at.
Corsair dont have a high-end series worth competing with anyone of the companies ive mentioned (Crucial, Geil, G.Skill, etc.). All that they have are products that cost just as much as high-end products, but arent.
Ive personally spoken about this issue with a friend of mine who is a Corsair representitive, and i assure u i know what im talking about.

The only good products Corsair and OCZ make are low-end, wich suck anyway, and extreme-end. Since anyone with 75 IQ points can realize that paying 600$ for RAM modules is pathetic, i can also rule out that class of modules, even though its the only class that they actually got right, and yes they got it very right.

Hit and miss? Do u actually know how to read a calender? Only modules created before May of 2006 (one year ago) were Elpida. All the new ones are pure Micron D9.

What? Corsair dont even use Micron D9 on their 6400 modules, how can u say that they are reliable??

800Mhz CL5 is worthless. You wont be able to overclock an inch.

I’m not quite sure why you’re all fired up.
Your choice is your own and 2006 modules are still on the market.
I own corsair modules and they are both Promos and Micron.
Your opinion is fine with me but it’s just an opinion.
CAS5 is fine for most applications at 800 MHz for a budget system.
The difference is how much voltage you have pump into the modules to run high MHz and low CAS timings.
My Corsair hovers DDR2 1000 4 4 4 12 @ 2.1 volts.
The super talent run 4 4 3 8 DDR2 800.
The promo cheap Corsair ram modules run 4 4 4 12 800 MHz and you can’t tell them apart form another product.
If you’re talking high end the price is not the deciding factor at all

You are certainly entitled to your opinion about brands but, your information is wrong. If you need clarification about our ICs used, look at the link below. Also, virtually every RAM company worth mentioning is currently making lots of memory with non-Micron ICs. Our modules are reliable and carry our lifetime warranty.

Could someone maybe explain (or point to a link) the difference about micron and promos chips? I couldn't find this info.

Edit: I did find some info. As I reckon, it has to do with overclockability - Micron chips overclock very well, Promos don't, right? That would explain the heated debates

Anyway, another question - I read that from Micron chips GKX is supposed to be better than GMH, but more expensive and hard to find.
I saw on the IC list at http://ramlist.infinityx.nl/ddr2/ that the high-end Kingston HyperX kits use it (PC2 8500 and 9600). One can buy the 8500 for around $240. So the question is - is the difference in performance worth the difference in price (as compared for example with $120 for the Ballistix kit)?

P.S. I was a bit suprised that no-one ever even mentions HyperX memory. Any reason for this? I had HyperX for the last 5 years and never had a single problem with it.

1 of the major differences between the current Promos ICs and the current Micron ICs is that the Promos has onboard voltage regulation on the IC. The Micron D9s don't. So, the Promos ICs don't respond to voltage increases like the Microns do.

The perception that Promos is bad is a wrong one. It's just that for OCing, Micron is currently better for hitting high frequencies. The Promos actually OC rather well considering and MANY companies are making memory with Promos ICs.

Micron D9 are the best RAM chips in the world.

It dosent matter how much u think that PROMOS are better, its not going to change the fact that they are nothing compared to Micron D9 and that the sky is blue.

Im sorry if me being fired up about this hurt anyone.. thats not my intent.
I just get so frustrated when ppl tell me that im wrong and that what i say is my opinion. Its bordering on religious belief and i cant stand that.
I want everyone to accept the objective truth.
