Kuesuny 4GB Kit (2GBX2) DDR2 667 sodimm RAM, PC2-5300 / PC2-5300S CL5 200-Pin Non-ECC Unbuffered Notebook Laptop Memory Modules

These are slim line memory modules and worked well as per description and so were compatible with the older system I have. These are fairly priced DDR2 667 DIMM RAM, PC2-5300/PC2-5300U CL5 240-Pin Non-ECC specification memory.

Received as expected.

These were bought to put into a old desktop with 4 RAM slots with max capacity of 8 GB in total to replace a total of 3GB. Delivered ahead of original stated delivery date. Removed old and replaced with all 4 new. PC would not boot. Removed and replaced with 1 2Gb only and would not boot just running without getting to boot stage. Put 2 x 2GB in and booted, recognised and System info showing 4GB. Tried 3 x GB and success again (started and showing 6GB). Put last one back in and again would not boot. Tried 5 times and same result. Put an old 1GB card back in and worked (showing 7 GB) so the 2GB card was definitely the issue. I was very careful when slotting the cards in and out. I reported to Amazon and they said I could return all 4 (not an option as I felt lucky that 3 worked so declined) but asked if I could just return the bad one - no BUT they gave me a 25% refund and said to keep the bad one, which I took. So 3* for the product and 5* for Amazon - hence 4* overall.
