Quick Question About System Bus Speed

Q: How does a computer process data? Memory should generally operate at least as fast as the FSB. I know because i am searching the same dell t5400 but knowing it is older, for some cheap price . If I'm gonna end up needing the DDR-800 in the furture it could be useful, but then it's mostly going to be staying in the same non-oc'd 4200+ system for quite http://olivettipc.com/quick-question/quick-question-on-system-partitions.html

You didn't provide the link, so I can only wonder why you sold 2GB RAM when you only had 4GB to start with. 4GB is perfect, 2GB can get some slower. XtremeData. Getting better RAM is good (You have to match every RAM in your pc though). thats how fast your ram can be.

Full Answer > Filed Under: Computers & Hardware Q: What is a system unit? When you say if the mobo supports it...let me give an example. DDR ram runs asynchronous to the cpu frequency. Gues that means the mb does have a 400MHz bus then eh??

The memory will run 5/4 times as fast as the FSB in this situation, meaning a 400MHz bus can run with the memory at 500MHz. I am currently running ddr2 800mhz but my board can support higher ,would it be wise to upgrade to the higher speed ram ? Increasing the front-side bus to 450 MHz in most cases also means running the memory at 450 MHz. My mobo has FSB of 1066/1333MHz.

Subscribed! Some empirical trials maybe necessary to find out if your apps run best at different memory ratios. It is related to ram clocks but not quite so much. @cdawall Your figures are on ddr3 specs, not ddr2. Not that I understand most of it My CPU's bus speed is 132mhz, My memory 's DRAM frequency is around 660 The FSBRAM ratio is 2:10 I'm running: i-5 760 (2.8ghz)

The 10% extra bandwidth at 733 MT/s is probably not worth the 20% extra cost. Originally, this bus was a central connecting point for all system devices and the CPU. but are there any systems in the last 10 years where RAM derives its speed from the FSB? –barlop Dec 3 '13 at 12:54 add a comment| up vote 0 down Answer questions posted by other students and gain points Get positive reviews by everyone who selects your answer as the best one More points means you're star student, ice cold cool,

What would be the proper ratio when I get the 1066 processor when I get it for the 667 memory?(I think I worked this out already, but would like someone to More about the author That is definitely bookmarked permanently. Now, this delay is expressed in terms of memory clock cycles, so with DDR2-533 CL4 memory, we're talking about 4 cycles / 266 million cycles per second = about 15 nanoseconds.

(This is also why it's called PC2-4200. check my blog By varying either the FSB or the multiplier, different CPU speeds can be achieved.

Motherboards purchased separately to build a custom machine are more likely to allow the user to edit the multiplier and FSB settings in the PC's BIOS. Many motherboards allow the user to manually set the clock multiplier and FSB settings by changing jumpers or BIOS settings.

DDR2 effectively operates at four times the FSB, and DDR3 at 8 times. yea whoops my math was a bit off then lol thanks for fixing my post Mar 4, 2011 at 9:52 PM #13 nesositel New Member Joined: Mar 4, 2011 Messages: Would I take much of speed hit (in gaming) if I use DDR2 800 instead of DDR2 1066?If I overclock the E6850 from 3.0 GHz to 3.3 GHz, will I need http://olivettipc.com/quick-question/quick-question-about-ram.html Help!

Actually I meant the DDR2-533 setting would require this ratio (this would be a 267MHz DRAM bus.)
