Question About Bus Speed And Ram.

Feb 27, 2007 #1 beef_jerky4104 Banned Posts: 822 I'm sure that it would stay at 667. One more LUL and I'm out roots of higher derivatives of exponential Is there a word for a statement which is false but comfortable to believe in? This is likely still slightly faster than two channels of DDR2-667 (same bandwidth but typically CL4—12.0ns or CL5—15.0ns latency, which is slower), and comparable to dual-channel DDR2-800 (12.8GB/s of aggregate bandwidth, It's an Asrock, it's kind of a board that bridges the gap between older boards and new ones, it has an agp port, ddr2 and ddr memory slots, and an ultra have a peek here

This is matched by a single channel of DDR3-1333, but at a cost of latency (7 cycles is quite a bitthis comes to 10.5ns). In this case the latency difference between CL5 DDR2667 and CL4 DDR2800 will be 5ns minus whatever some variable amount lost to crossing clock domains with DDR2800, basically nothing that you'd well only... DDR2 doesn't take as well to overclocking as processors.quote:Will the system performance be significantly impaired if DDR2 1066 RAM is used instead of DDR3-1600? http://www.techspot.com/community/topics/question-about-bus-speed-and-ram.71065/

By going with DDR2-667, you can keep voltage at default in contrast to some DDR2-800. The ram is: CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model TW3X4G1333C9DHX - Retail Please let me know if you Already have an account?

  1. However, the "memory standard" is DDR2-800.
  2. What would happen if I put in a DDR3-2133 RAM chip together with the CPU, if the motherboard supports the faster RAM speed?
  3. When you say if the mobo supports it...let me give an example.

  7. Even if you put in DDR2-800 it should stay at that speed.
  8. Overclocked to 3.0 GHz, it'd try to use the same 10x divider, so you'd end up with a memory clock rate of 300 MHz.
  9. For example right now I can buy 2x8GB 1333MHZ CL9 RAM for Apple Laptops for EUR 106.50 or the same with 1600MHZ CL11 RAM for EUR 102.00 from Amazon Germany from
  10. Meanwhile, I have an old 533 bus speed p4 processor laying around.

I don't think it's actually overclocked (much).

How can I avoid being "the negative one" when giving feedback on statistics? Join the community here, it only takes a minute. Am I going to notice a difference in the bus/ram speed difference or just stay with the one I purchased?thanks Posted on Jan 17, 2009 7:42 AM Reply I have this http://www.tomshardware.com/forum/282479-30-question-speed Newer Than: Search this thread only Search this forum only Display results as threads Useful Searches Recent Posts More...

With the AMD Athlon64, since the FSB controller is actually on the chip itself, the CPU will tend to force a specific bus speed. With DDR2-667 CL5 memory, which is about the same price these days, you get about the same latency (5 cycles / 333 million cycles per second = 15 ns). Once upon a time, it was always a good idea to try to match your memory speed to your FSB speed; decoupling them was always bad for performance. Login _ Social Sharing Find TechSpot on...

So buying the faster rated memory is a waste of money unless you plan to change the CPU soon enough. For best performance, you want the memory clock as high as possible.

Check This Out I feel stupid.

The latency characteristics remain the same as I outlined earlier.PCs will not see an advantage from using DDR3 until the next generation microarchitecture, codenamed Nehalem, which will integrate a memory controller And if so why is it only running at 266 MHz when the ram says on the box 667/533/400, does the speed depend on something else, say my motherboard? To compensate, there's a cache system and at worst case, a cpu idle-wait state (ie waiting on data).

I'll try to clear this up for ya... to elaborate, My motherboard supports ddr sdram (sodimm) with a speed of 166 mhz. Thanks a bunch! Anything past this is going to get you significantly diminishing returns, and you will probably see no performance improvement (aside from cognitive dissonance and placebo effect, both things inside your head).

The 10% extra bandwidth at 733 MT/s is probably not worth the 20% extra cost. would running ddr2-800 @ 400 MHz on a 2000 Mhz clock speed (eg 3800+) necessarily give better performance than running ddr2-667 @ 333 Mhz ?obviously i'm now enlightened as to the
