Solid mainstream performance for DDR2 memory.
Older classes of motherboards (mine is an Asus P5QD) that use DDR2 memory can still be effective modern PC's. I upgraded my system to this 8GB of RAM, a 64 bit OS and an SSD. Afterwards, it was more responsive than my newer i7 workstation with a rotating hard disk drive. This 800MHz/PC2-6400 memory had one (unrepeatable) memtest86 error in 12 hours of testing and performed flawlessly in 2 weeks of usage. The memory bandwidth was reported as 4,496Mbyte/sec by MEMTEST86+. This memory was taken out of service by me when I was able to replace it with 8GB of faster 1066MHz/PC2-8500 memory that reported 5,322Mbyte/sec band width. The noticeable system performance was small. While I highly recommend this upgrade to others, it is likely the terminal upgrade for my machine. Each stick of memory provides 2GB, while 4GB memory/stick would allow expansion to 16GB total in motherboards of this era, compatible 4GB sticks are hard to find, very expensive (4x more / Mb) and not generally cost effective. This PC2-6400 memory is really the most cost effective, compatible and reliable upgrade solution, in my opinion.Verified purchase: YesCondition: Pre-owned

Bad Memory
One, or both, of the memory were bad, and caused the system to blue screen whenever they are installed as a 2nd pair to an identical pair already in use.Verified purchase: YesCondition: Pre-owned

Matched what I was adding to
I have an old Pentium D desktop running windows 10 pro with 4 gb of memory (4 - 1 gb sticks). 4 gb of memory is not enough for windows 10 so I decided to upgrade to see what it would do. I had 2 - 2 gb sticks of this memory in my stock and wanted to add 2 more 2 gb sticks for a total of 8 gb which is the maximum amount this system will hold. After the upgrade and some tuning, the machine responds much better. Next upgrade will replace the Pentium D processor to a quad core processor to see what it will do to performance. i know an SSD will help performance but I like to experiment on this older machine.Verified purchase: YesCondition: Pre-owned

Solid RAM purchase
These RAM modules work great. I ran some benchmarks and Lynx has shown zero errors after several hours. Good value and it provided some fresh spirit for my good ole' PC. RAM was decently packaged, each module was in a separate box and all was wrapped with some bubble wrapping.Verified purchase: YesCondition: Pre-owned

Works well. Extended the EOL on my ancient system.
This is good, reliable RAM. I used the Corsair XMS 1GB sticks for almost 10 years with no problems. These were manufactured at the same time and are just as good. I have read that Corsair quality has deteriorated in recent years, but this model predates that.Verified purchase: YesCondition: Pre-owned

Installed New Memory Corsair
The Corsair 4GB 2x2GB worked perfect. I like how the seller stood behind the memory with a 30day refund. After installing, I did a Memtest to verify the memory had no problems. Zero Problems.! Thank you and Great PriceVerified purchase: YesCondition: Pre-owned
