Personally, the original Hyundai and Samsung memory are the most compatible and stable memory chips at present, which are much more practical than many widely publicized memory chips. In addition, particles such as D43 of Hyundai "Hynix Semiconductor Inc" are also widely used in many high-frequency memories. At present, the modern high-frequency bar with great value on the market has the original DDR500 memory, and the HY5DU56822CT-D5 memory chip packaged by TSOP is very cost-effective.
2. Kingston
As the largest memory manufacturer in the world, Kingston's memory products have won the hearts of many consumers in China with their excellent product quality and first-class after-sales service since they entered the China market.
However, although Kingston is the world's largest memory manufacturer, Kingston brand memory products use a wide variety of memory particles, including Kingston's own products, and more are Hyundai, Samsung, South Asia, Winbond, Infineon and Micron.
Kingston's high-frequency memory includes Kingston DDR400, DDR433-DDR500 with "Hynix”D43 particles and Warburg memory particles, which belong to ValueRam series (economical) and HyperX series respectively.
HyperX series
Kingston's ValueRam series has the same price as ordinary DDR400, but it can be overclocked to DDR500. Kingston's HyperX series overclocking is also good. Kingston's 500MHz HyperX overclocking memory (HyperX PC4000) has a single-chip package with the capacity of 256MB and 5 12mb, and a dual-chip package with the capacity of 5 12mb and 1gb. Its voltage is 2.6 volts, and aluminum fins are used to enhance heat dissipation. Using Samsung K4H560838E-TCCC chip, the CAS value is 2.5 under DDR400 and 3 under DDR500, so the performance is also average.
3. Li Ping
Li Ping is a newly rising memory rookie. Liping Technology (Shenzhen) Co., Ltd. is headquartered in San Francisco, a picturesque world high-tech town in the western United States. The company is committed to the research and development, production and sales of Liping LPT extreme high-end memory chip products. The company has a skilled product research and development team and a professional sales team, which have traveled all over China and abroad. Products are deeply loved by gamers and overclocking enthusiasts. At the same time, it is known as the "god of overclocking".
In addition, there are brands such as Kinghourse, South Asia and Micron, which are all good choices, so I won't go into details here.
"Liping" Cobra DDR400 series memory is also specially designed for players who pursue performance. D43 particles are also used, but the timing is higher. In order to strengthen heat dissipation, metal fins are added. Its overclocking ability is quite strong, and it can overclock to DDR520 at a voltage of about 0.1v. Liping's DDR466 memory uses Samsung granules numbered K4H560838E-TCCC, and the memory sequence is 3-4-4-8 when it runs in DDR466, but its 256MB capacity is close to 500 yuan's quotation, which is too high.
On the other hand, the high-end memory DDR560 in Liping provides single-chip packages of 256MB and 565,438+02 MB, and dual-chip packages of 565,438+02 MB and 1024MB support dual-channel architecture. There are copper fins on the surface of each memory to ensure the stability of operation, and its CAS value is 3, which can only be said to be just easy to use.
diligent
Twinmos) DDR433 memory with CAS 2 is packaged by CSP technology. This memory has good performance index, with CAS delay of 2 and burst length of 2, 4 and 8. In addition, the memory is covered with a golden memory cover, which can play the role of heat dissipation and shielding, and a heat conductive gasket is filled between the memory particles and the heat sink. The price is around 350 yuan, the transcendence is unambiguous, and the cost performance is good.
5. Kim Max wins the creation
Founded in 1989, Shengchuang Technology Co., Ltd. is a top 200 manufacturer in Taiwan Province Province, China (May 2000) and a leading manufacturer of memory modules.
Through strict quality control and perfect R&D strength, Shengchuang Technology has obtained ISO-900 1 certificate and established cooperative partnership with the best enterprises in IT industry. With innovative design technology and the belief of pursuing perfection, the company produces high-performance cutting-edge scientific and technological products, and constantly provides the best memory module with low price and good quality to the mobile computing field.
During the SDRAM period, Kingmax successfully built the PC 150 empire, which opened the high-speed era of memory products and established Kingmax's leading position in the memory field. Now that DDR is coming, from 266 to 300, and now to 500, Kingmax has always maintained a leading position and continues to lead the development direction of memory. Speaking of KingMax memory, we can't help but talk about its unique patent of "TinyBGA" packaging technology-as the world's leading DRAM manufacturer, Shengchuang Technology announced the first memory module based on TinyBGA packaging technology at 1997. This award-winning packaging technology can package 3 times the memory capacity of ordinary technology in the same volume. At the same time, Shengchuang Technology has also developed 1GB StackBGA module designed for high-end servers and workstations, FBGA module designed for DDR application, and inverted BGA/DCA module designed for Rambus RIMM application, with the speed of1.6 GB/s. ..
Kingmax Shengchuang launched a low-priced version of DDR433 memory product, which uses the traditional TSOP package memory chip and works at 433MHz. Kingmax's SuperRam PC3500 series is priced at the same level as PC3200, which provides a good choice for those users who are keen on overclocking and are not well off. In addition, Kingmax also introduced the DDR500 memory product of CL-3, whose performance is similar to that of similar products from other manufacturers.
6. Pirate flag
Pirate Flag is a distinctive memory brand, and its memory chips are all wrapped in a black metal shell, which is closely attached to the memory particles, on the one hand, it can shield other electromagnetic interference. Its representative products, such as Corsair Twinx PC 3200 (CMX 512-3200XL) memory, can run stably under CL2-2-2-5-T 1 under DDR400, and the delay and addressing time are shortened by half. This memory is not worse than some DDR500 products, and the pirate ship is this kind of memory.
Pirate ship DDR500 uses Hynix chip. This XMS4000 can run stably in DDR500 and overclock to DDR530. Under DDR500, its CAS value is 2.5, and its performance is good.
7. Apache (Yu Zhan)
In the memory market, Apache has always had a good reputation, and its WBGA package in SDRAM era has been ringing for a while, and it has also established a good image in DDR memory. Yuzhan Technology belongs to Acer Group and has strong strength. Initially focusing on memory chip marketing, it has become one of the four largest memory chip suppliers in the world. According to authoritative sources, internationally, Yu Zhan's brand awareness and product sales are equivalent to or even more than those of top brands in China. At present, Yu Zhan has not occupied a leading position in China because it has kept a low profile in brand promotion and put more energy into product development and production rather than brand promotion.
Recently, Yu Zhan launched the "Yu Zhan Golden Memory" series. Yu Zhan Gold Memory Product Line is specially designed for memory users who pursue high stability and compatibility. Yu Zhan Gold Memory insists on using 100% original factory test particles (OEM particles are never used), is designed based on the latest DDR memory technical standards, and is manufactured in a factory certified by ISO 9002. It adopts 20 micron gold finger high-quality 6-layer PCB board, and each memory is covered with beautiful and exquisite gold metal nameplate. After passing the highest-end Advantest test system, it is built with high-speed SMT machine, and it has been strictly tested and fully compatible with high and low pressure, high and low temperature and long-term sealed space by world-renowned system and motherboard manufacturers, ensuring the quality and compatibility to the maximum extent.
Yu Zhan's DDR500 memory (PC4000 memory) is matched with gold heat sink and green PCB. The material of the metal radiator is quite good, and it feels heavy in your hand. In order to prevent oxidation, its surface is plated with gold. In terms of memory granules, this memory adopts Samsung's memory granules, the specific model is K4H560838E-TCC5, and it is a TSOPII encapsulated granule with specifications of DDR466 @ CL = 3. The standard operating voltage is 2.6V+-0. 1V, and the standard operating sequence CL-tRCD-tRP is 3-4-4. Under DDR500, its CL value is 3, and its performance will be poor.
