How To Match Cpu Motherboard And Ram
noob question here, I just got confused by this.

But, looking at newegg/intel, the stock FSB is 1066mhz, wtf?! Since DDR-400 RAM is used then effective memory clock (Actual Memory Frequency) will be 500MHz. It'll be pretty much just as fast as say 5-5-5-15 1066MHz RAM (as an example). I'd guess that your answer is in your screenshot. http://www.techspot.com/community/topics/cpu-fsb-and-memory-frequency.38154/
How To Match Cpu Motherboard And Ram
What would the ratio be if possible? Many questions about RAM/CPU/FSB matching solved Mobo FSB and CPU FSB. Here's a screenie of my E5400 with a higher 1333 FSB at an initial overclock stage where I merely upped the FSB and reduced the mutiplier while I checked the 1:1
They still sell single sticks of ram. One of the primary reasons for X58 vs P55 is RAM the other PCIe along with 6-core CPUs.-> There's no 'good' way to add an 'odd' stick later. There isn't a clean way to use an integer divisor on these clock rates (the cleanest way to derive a slower clock rate is to simply "divide" the clock by an Fsb Dram Ratio Pump: MCP355, w/Petra's top Radiator: 120.3 Thermochill Waterblock: Apogee We'll see how it pans out.

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 http://www.semiaccurate.com/forums/showthread.php?t=4196 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).

this means you ram will be at DDR890, but if you use 500fsb x 8 = 4000 you can run the ram at DDR1000 at 1:1 and get the best performance. Cas Latency 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? Dual-channel DDR2-800 can feed this FSB adequately, as can single-channel DDR3-1600 (or dual-channel DDR2-1066, or dual-channel DDR3-1066, or dual-channel DDR3-1333).
The ratio between DRAM and FSB is commonly referred to as "DRAM:FSB ratio". It seemed to me if the CPU is the bottleneck (by comparison only) slowing down the ram will not help. Why not just tighten the memory timings to say 4-4-4-12 at 800MHz? Cpu-z Follow @teamevga Back to Mobile Register Help Remember Me?
using what you give above you need 445mhz to run 4ghz on 9x. A normal DDR-400 SDRAM will fail to work at 500MHz since it is designed to work at 400MHz and system will become unstable. You can generally find DDR3-1066/PC3-8500 (CL7), DDR3-1333/PC3-10600 (CL7 or CL9) and DDR3-1600/PC3-12800 (CL7 or CL9).As far as bandwidth is concerned, current Intel processors come with 1333MT/s FSBs (10.6GB/s of system bandwidth). http://divxeo.com/how-to/bad-motherboard-symptoms.html Kebo Ars Scholae Palatinae Registered: Nov 19, 1999Posts: 1452 Posted: Tue Oct 09, 2007 10:43 am http://anandtech.com/memory/showdoc.aspx?i=2900&p=6Anandtech has a bunch of memory articles showing performance.The benchmarks are shown specifically to show
Is doing this is even safe for the system? I realize how newbie all these questions must sound, I can only say that any help would be greatly appreciated. But remember you have another choice here anyway. I'm planning on buying a C2D E6600, at stock the cpu is at 240mhz FSB x 10 = 2.4ghz.

Would any part of the CPU take any damage if i increased the FSB and lowered the CPUs multiplier to lets say: FSB 266MHz x4 = 1066MHz RAM 533MHz x2 =
With it's 14x multiplier this gives me a nicely stable 3.7GHz CPU.
