Quick Question About System Bus Speed

For example, if a motherboard (or processor) has its bus set at 200MHz and performs 4 transfers per clock cycle, the FSB is rated at 800 MT/s. Welcome to the Ars forums.It depends entirely on the CPU workload, of course. It consists of three groups of wiring known as the address bus, control bus and data bus.

For ddr2 the proper ratios would be 667 is 1:1 and 533 is 4:3. Great! Feb 9, 2011 at 11:35 PM #5 Nailezs Joined: Jul 14, 2009 Messages: 890 (0.32/day) Thanks Received: 75 Location: Baltimore, MD System Specs System Name: Cool Runnings Mark 2 Processor: i7 Not just any DDR2.

It's going to be way overkill, but yes.quote:Originally posted by pepsi_max2k:How much does using a faster DDR2 memory module/speed affect overall athlon system performance? The time now is 13:34. My System Specs Computer type PC/Desktop System Manufacturer/Model Number Custom Asus Build OS Microsoft Windows 8.1 Pro 64-bit CPU Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz Motherboard B85M-E Memory 8.00 GB Graphics The effective speed of DDR depends what kind of DDR you have.

This wikipedia article is a good stating point. A: A system unit is the metal case that houses and protects other computer components, such as the motherboard, hard drive, RAM, graphics card and central pro... favourite memory expert, maybe you can help...see http://episteme.arstechnica.com/eve/forums/a/tpc/f/77909774/m/634009729831why would DDR667 set 667 in bios and a 4200+ X2 (windsor) at auto settings (presumably 200 * 11) be reading as DDR735 in Finally at a "DDR2-800" setting it'd try to use a 7x divider, so at 3.0 GHz, the memory would run at 428 MHz.So if you have DDR2-667 rated memory with an

Bug or feature? Increasing the front-side bus to 450 MHz in most cases also means running the memory at 450 MHz. AMD. ^ "An Introduction to the Intel QuickPath Interconnect" (PDF). Other buses like the Peripheral Component Interconnect (PCI), Accelerated Graphics Port (AGP), and memory buses all connect to the chipset in order for data to flow between the connected devices.

What is Dual Channel Memory & How do I use it Correctly? :: LEGEND Corporation :: Performance Technology Just 2 memory lanes paired together vs the single, I have seen both Even the newest Phenom processors can use any DDR2 down to DDR2-400.quote:I'm currently trying to decide whether to purchase some DDR-667 (5-5-5-15) or DDR-800 (5-5-5-12). if you pop 1 in black and 1 in green you run at single channel. Note that DDR3-1600 CL7 cannot be beaten by the fastest widely available grade of DDR2, but wins by half a nanosecond while being several times more expensive.In each case, DDR3 is

This would have to be part of your motherboard, not the ram.

Don't the CPU bus and motherboard bus have to match in order to work??? As an example, take the 2.6 GHz Athlon 64 X2 5200+ used with DDR2-667 RAM.

The tutorials give you ample warnings, just be careful: Optimize Windows 7 Brink is a genius.

Its hard, complicated, and a lot of people don't recommend it due to stability issues and the possibility of breaking your pc, but overclocking is a method of increasing speed. Which also means I could try get the 667 up to 733 as that's what the 800 would run at.

even setting to 533 gives something like DDR551??? as i saw in your table above, 735 would indicate DDR800 speeds with a 4200+, but it's set at 667... It currently has 1 4gb stick of Corsair Vengeance 4GB (1x4GB)1600MHz DDR3 PC3-12800 RAM.

By varying either the FSB or the multiplier, different CPU speeds can be achieved. With two channels working simultaneously, the bottleneck is reduced. Not just any DDR2. Whether or not the old processor is supported depends on the motherboard's chipset.

Transfer rates[edit] The bandwidth or maximum theoretical throughput of the front-side bus is determined by the product of the width of its data path, its clock frequency (cycles per second) and The FSB speed is the speed of the link between the processor and chipset.The memory speed is the speed of, well, the memory and its bus to the chipset.Modern chipsets can If the clock is divided by 7, you get 371 MHz, which is too high for the RAM's rating (333 MHz). navigate here An example FSB may run at 133 MHz, with a (slow) processor running with a multiplier of 9 to give it a speed of 1.2 GHz.

When a memory controller makes a request to memory, there are several cycles it has to wait ("latency") before it can get data. Pass word one-by-one and replace (Search and replace with confirmation) Why is the flight from US cities to Vietnam cheaper than from Vietnam to a US city? In newer systems, it is possible to see memory ratios of "4:5" and the like. Would the system run like junk if at all?
