Obsolete addressing modes\nThe addressing modes listed here were used in the 1950-1980 time frame, but most are no longer available on current computers. This list is by no means complete; there have been lots of other interesting/peculiar addressing modes used from time to time, e.g. absolute plus logical OR of 2 or 3 index registers.\nMulti-level memory indirect\nIf the word size is larger than the address size, then the word referenced for memory-indirect addressing could itself have an indirect flag set to indicate another memory indirect cycle. Care is needed to ensure that a chain of indirect addresses does not refer to itself; if it did, you could get an infinite loop while trying to resolve an address.\nThe DEC PDP-10 computer with 18-bit addresses and 36-bit words allowed multi-level indirect addressing with the possibility of using an index register at each stage as well.\nMemory-mapped registers\nOn some computers the registers were regarded as occupying the first 8 or 16 words of memory (e.g. ICL 1900, DEC PDP-10). This meant that there was no need for a separate 'Add register to register' instruction - you could just use the 'Add memory to register' instruction.\nIn the case of early models of the PDP-10, which did not have any cache memory, you could actually load a tight inner loop into the first few words of memory (the fast registers in fact), and have it run much faster than if it was in magnetic core memory.\nLater models of the DEC PDP-11 series mapped the registers onto addresses in the input/output area, but this was primarily intended to allow remote diagnostics. Confusingly, the 16-bit registers were mapped onto consecutive 8-bit byte addresses.\nMemory indirect, auto inc/dec\nOn some early minicomputers (e.g. DEC PDP8, Data General Nova), there were typically 16 special memory locations. When accessed via memory indirect addressing, 8 would automatically increment after use and 8 would automatically decrement after use. This made it very easy to step through memory in loops without using any registers.\nZero page\nIn the MOS Technology 6502 the first 256 bytes of memory could be accessed very rapidly. The reason was that the 6502 was lacking in registers which were not special function registers. To use zero page access an 8-bit address would be used, saving one clock cycle as compared with using a 16-bit address. An Operating System would use much of the page, so it was not as useful as it might seem.\nScaled index with bounds checking\nThis is similar to scaled index addressing, except that the instruction has two extra operands (typically constants), and the hardware would check that the index value was between these bounds.\nAnother variation uses vector descriptors to hold the bounds; this makes it easy to implement dynamically allocated arrays and still have full bounds checking.\nRegister indirect to byte within word\nThe DEC PDP-10 computer used 36-bit words. It had a special addressing mode which allowed memory to be treated as a sequence of bytes (bytes could be any size from 1 bit to 36 bits). A 1-word sequence descriptor held the current word address within the sequence, a bit position within a word, and the size of each byte.\nInstructions existed to load and store bytes via this descriptor, and to increment the descriptor to point at the next byte (bytes were not split across word boundaries). Much DEC software used five 7-bit bytes per word (plain ASCII characters), with 1 bit unused per word. Implementations of C had to use four 9-bit bytes per word, since C assumes that you can access every bit of memory by accessing consecutive bytes.

Simply stated, dual-channel memory architecture splits the available RAM into two data channels, resulting in a bandwidth, or data-transfer rate, that's double that of a single-channel system.\n\nDual-channel mode requires that you install identical or "matched" RAM modules. Matched modules have the same physical number of chips in the same physical configuration. Physically dissimilar modules, even of the same capacity, may not work as well. You also need to insert the modules in specific slots. If you have four slots, for instance, you'll need to insert the matched modules in the first and third or second and fourth slots.\nIf you want to double-check whether your memory configuration is indeed running in dual-channel mode, Memtest86+ ("http://www.memtest.org/#downiso") reports this information.

easy...\n\ngo to kingston.com and use their ram wizard...  No guess work.\n\nAnoosh's suggestion just uses the system info in the registry.  It can be inaccurate.

Its always been my experience that mhz help more than cache, but i'm an AMD guy. Intel is bottle necked at the fsb so the cache may actually help you more with the constant look ups it won't have to wait on the slow bus if a lot of info is already cached, you could always go Opteron :)

RDRAM is completely different from ddr2, ddr3, etc.  You'll need to find pc1066 RDRAM.  As no current motherboards support these modules, they are not as widely available and are somewhat more expensive.  You might want to consider a full upgrade.

I have one of these.\nRAM is RAMBUS(proprietary) - it is expensive\nCPU is socket 423-pin(outdated) - maximum 423-pin is 2 GHz \nCheck this out though, for full upgrade compatibility\nhttp://www.powerleap.com/

Those are memory addresses. that means your RAM is bad most likely. 90% i would say

Hmm, I think it's simple addition. The cores are all identical. So if pushed to the limit, it should perform *close* to three times the original, namely 3.2 x 3.

Do you mean cache memory?\nCache is a special static memory built inside the processor. Typically there are two kind of cache, first is L1 cache that is located inside the CPU chip. This cache is very fast, providing space for storing instructions for the CPU to execute. Usually it is 32Kb to 64Kb in size.\nThe second one is L2 cache that is located outside the CPU chip but still in the processor area. This act as the secondary cache supplying L1 cache with more instructions. This type is larger in size ranging from 256Kb to 2Mb.\nRegister is an internal circuit in CPU built to store instructions, address, temporary results and operands. When processing an instruction, a CPU needs space to store information that is needed to perform calculation of the instruction like operands, jump address, modulus etc. This is where registers are used. The size of a register is very small, about 16bits to 64bits. A CPU can have many register, usually 16 to 32 registers.

Take one of your sticks of ram out of your computer and look at it. It should say on the ram what kind it is and you can also see how many pins it is.

That's a "C" with a square in it.  The module is manufactured by Celetronix. Compare what you have with this: http://1006.tchosts.net/TEMPLATES/Template1/product.asp?intProdID=512MB+SDRAM

On an SMP system, Inter Processor Interrupts are used to coordinate with other processors. Is this what you are asking about?
