HASH(0xa332d0c0) out of 5 stars Corsair all the way! May 15 2010

I bought this RAM for a gaming computer that I was building. I'm running the Intel DP55KG motherboard with the Intel Core i5-750 processor and with the Corsairs, my gaming and computing experience has been unbelievable.

Corsair has continued to not let me down. I highly recommend this product to anyone!

HASH(0xb81e6444) out of 5 stars This memory was bad May 12 2011

This memory was bad. Caused random crashes and BSODs

I wound up replacing the motherboard (also new) before trying swapping the memory out, as the windows memory tests passed.

Fortunately I returned this, and got new memory (Patriot), and I was in business. I know lots of people like Corsair, but I've only bought one other memory stick from them a few years ago, and it was bad too. I wasn't trying to overclock or anything.

HASH(0x9c4c699c) out of 5 stars NOT SO MUCH Oct. 21 2011
By old read fanatic - Published on Amazon.com

Bought this RAM for my AMD Phenom II X4 system with a GIGABYTE 880 GA-UD3H mother board because it said Guaranteed to work with AMD systems. Unfortunately for me at least that simply is not true. I got one set that tested BAD and returned to AMAZON and they gladly and quickly sent me another matching dual core set. However even with that replacement my system was unstable, updates failed,programs failed to install correctly and many other issues including lots of blue screen and Firefox crashes. I replaced this RAM with Crucial Ram of similar speed etc and all my issues were gone instantly! I'd not recommend this RAM to anyone with an AMD system. I can't speak to an Intel system as I have never had one. At least Corsair has agreed to take them back I assume they will send me some new sets though I'll have no use for them) and expect replacements soon, as the return time limit with Amazon has expired.

HASH(0x9c101a08) out of 5 stars Awesome Memory but half satisfied:( July 7 2011
By SayeedR - Published on Amazon.com

Corsair memory is the best, using them for more than 6 years, my first disappointment ever with a 2 GB module, my recent purchase of a dual channel kit one module failed its faulty, it passed the POST test, after about 10 minutes of uptime it sends my pc into BSOD, tested all the memory slots, its failed, in another pc it failed. Wish i could have it replaced but where i live In Guyana its no use. But in all corsair memory rocks will continue to use it.

HASH(0x9c281570) out of 5 stars Pretty good for now, will be updated Dec 18 2011

I bought this ram to go along with my new system.

Intel quad core 9550 chip, Intel p43 core 2 quad core ddr3 1333MHz FSB.
The case is a Cooler Master Elite 430.
Two additional computer fans
Cooler Master 700W PS
GeForce XF520 Extreme Gamer 2GB VRAM DDR 3
Sound Blaster X-Fi Extreme Gamer

I also added VIA VL chipset USB3.0 (4ports) and Fire Wire A(1)B(2)

My system is much faster than my previous one Dell Vostro 230.

I am going to upgrade the RAM for additional 4GB. (This is how much the Motherboard will allow me).

I am going to add after market CPU cooler Cors Air Hydro H80. (So I can try over clocking the CPU).

I haven't had any problems yet and the system is running smoothly.

Much better flow and much much faster.


So I received my new additional RAM.

However the RAM is BAD.

I contacted Amazon and they told me I will receive my replacement RAM by Friday (12/23/11) and they are paying for my return shipping as well.

Will post again when I receive the replacement RAM.

On the window testing, my RAM has scored 7.2 out of 7.9 possible.

I do have additional 2GB another Corsair RAM.


I am impressed with Amazon's contingency plan.

The RAM actually got here on time.

New RAM is working just fine and they are in my system as we speak.

As of morning time and through the lunch yesterday (HST) new RAM was not scanned yet to go out from PA.

Let's face it. I live in a beautiful place; Honolulu, but it also is most issolated metropolis in the world.

I had my doubts.

Going out scan was done around 5 PM.

Receiving scan being done after all the delivery trucks would have gone out after 9 AM.

But the tracking record indicated the RAM was out for delivery by noon, lunch time.

When I came home in the evening around 6PM, it had already been delivered to my place.

I opened it (packaging and opening was easy) and installed it.

I am a happy man.

Thanks Amazon.
