Memory upgrade
Users questions: Processor: AMDAthlon (Athlon) 643 800 + Motherboard: Dell 0HY175 Chipset: NvidiaC51 Memory: 1GB (Samsung DDR2533MHz) [2 512] on the configuration I want to upgrade memory to 2GB is not considered whether to stop companies Stock market has not produced on the machine I am now able to support the CPU board to upgrade the memory as a prerequisite for the best which is the case? A [original two memory still retain] 1: buy 2 512MB of DDR2533MHz dubbed 2G memory plus 2: buy a 1GB of DDR35 33MHz plus B [original two memory not of] 1: to buy a 2GB memory modules of DDR2533MHz 2: buy two 1GB memory modules of DDR2533MHz C [otherwise] is not there so few words you summed up users ? {1 ** cpu bus frequency Should be equal to or less than the motherboard's front side bus (FSB motherboard is like 1600, cpu bus frequency is 1333, so the best cpu performance can play); 2 ** cpu bus frequency must be greater than or equal to the frequency of memory (such as cpu 1333 bus frequency, memory is DDR 31333, then the memory can play the best performance, if the two DDR31333, reasonable to say that is a waste, but the performance has improved, but not obvious! ! If the two DDR21066, then it is not wasted, if only on a DDR21066, then memory is the bottle Neck, and keep up with the 1333 cpu frequency! )} Satisfy the above two cases is one of the best mix of ****** digression then my motherboard chipset supports the higher frequency of memory? Frequency up to much? Whether to support the DDR3 memory? Also consider the total CPU front Line and support for dual-channel case, if "AMDAthlon643800 +" FSB 1000MHz, the memory type is the highest it supports dual channel DDR2667MHz? So, having said so much, that is, would like to help me weigh master, my machine The CPU motherboard chipset for what memory? Higher frequencies can not change the memory? Where can high-step? From the current situation, it seems that for two 1GB of 667MHz or a 2GB of 667MHz is the better upgrade? Please correct me, not many points, and all Department offer Thank you! I want to upgrade to 2GB memory capacity [CPU: AMDAthlon643800 +] see this is not a dual-core CPU can not support two of DDR2800MHz 1GB of memory? Trouble made to support your answer based on that [AMDA thlon643800 +] specific performance parameters, send a link to your motherboard may chant
Experts answer: supports up to DDR2800 memory, whether you like little dual channel is recommended for a 2GDDR2800 memory.
