ALKETRON - 4GB DDR3 Standard RAM(Memory) - 1600MHz - CL11 - UDIMM - PC3-12800u - for Home & Office Desktop PC - 3 Year Warranty (4GB-1600MHz, Black Unicorn Series)

I was sceptical about buying it on the first hand. I did some research and bought it because of my budget constraints and ofcourse the kind of PC I had to install it with. To my surprise the quality and performance was really good for a tech piece like this for this price. I am truly happy that my pc is now runs faster and boots quickly running windows 10.

Product came within the stipulated date of delivery, in brand new condition. It was easy to install on my PC motherboard and works perfectly. Quality is above average. Value for money. I was doubtful at first as I had never heard of the company so I took a gamble and it actually paid off ! :)

Working well perfect specs

Finding a DDR3 RAM for older boards like H61 is tough these days. I just brought two 8GB DDR3 RAM sticks to get maximum out of the motherboard on my 13yr old PC. Although the cpu is intel core i3 2100, which hits high cpu usages at times due to aging, still the 16gb ram upgrade can make day to day tasks easy. I think the RAM sticks are value for money too, buying on Amazon saved me more than from the official site. I have still kept my old 4gb ram stick for backup purpose, because getting a DDR 3 RAM might be tough in the upcoming days. If you have an old PC build like me, which you still use on daily basis. You can improve its performance by installing maximum RAM capacity your motherboard allows. I will definitely recommend buying this RAM stick for the quality and speed boost. Booting time will also improve, if you add maximum allowed RAM, thus adding it to overall performance. Always check your motherboard compatibility, before ordering RAM of any company. This RAM is downward compitable, so it works fine on H61 (Asus P8H61 MLX Rev 3).

Ram stopped working after 2 years but still in under warranty, has to send memory to Bangalore office without our own expense, terrible product,.

Good but not replaceable facilities.

I was looking for tcl-10 ram. My earlier 2 nodes were hyperx by kingston, the price of which is 5x of this ram module currently.Adding ram characteristics, for anyone looking to buy this. Will update review after some weeks of usage. if not updated, then product is working good.Decoding EEPROM: /sys/bus/i2c/drivers/at24/0-0053Guessing DIMM is in bank 4---=== SPD EEPROM Information ===---EEPROM CRC of bytes 0-116 OK (0x5CAD)# of bytes written to SDRAM EEPROM 176Total number of bytes in EEPROM 256Fundamental Memory type DDR3 SDRAMModule Type UDIMM---=== Memory Characteristics ===---Maximum module speed 1600 MHz (PC3-12800)Size 8192 MBBanks x Rows x Columns x Bits 8 x 16 x 10 x 64Ranks 2SDRAM Device Width 8 bitsBus Width Extension 0 bitstCL-tRCD-tRP-tRAS 11-11-11-28Supported CAS Latencies (tCL) 11T, 10T, 9T, 8T, 7T, 6T---=== Timings at Standard Speeds ===---tCL-tRCD-tRP-tRAS as DDR3-1600 11-11-11-28tCL-tRCD-tRP-tRAS as DDR3-1333 9-9-9-24tCL-tRCD-tRP-tRAS as DDR3-1066 7-7-7-19tCL-tRCD-tRP-tRAS as DDR3-800 6-6-6-14---=== Timing Parameters ===---Minimum Cycle Time (tCK) 1.250 nsMinimum CAS Latency Time (tAA) 13.125 nsMinimum Write Recovery time (tWR) 15.000 nsMinimum RAS# to CAS# Delay (tRCD) 13.125 nsMinimum Row Active to Row Active Delay (tRRD) 6.000 nsMinimum Row Precharge Delay (tRP) 13.125 nsMinimum Active to Precharge Delay (tRAS) 35.000 nsMinimum Active to Auto-Refresh Delay (tRC) 48.125 nsMinimum Recovery Delay (tRFC) 260.000 nsMinimum Write to Read CMD Delay (tWTR) 7.500 nsMinimum Read to Pre-charge CMD Delay (tRTP) 7.500 nsMinimum Four Activate Window Delay (tFAW) 30.000 ns---=== Optional Features ===---Operable voltages 1.5VRZQ/6 supported?
