Core2's are very good at hiding memory latency, and are pretty insensitive to memory speeds as far as actual application performance goes.Common case is probably overlapping transactions hitting an open page, I think you will need to upgrade more then your processor.

If you disable Hyperthreading through the bios, it will run at your ram/motherboards default Subject: Re: Can you put an 800Mhz FSB CPU in a 533Mhz FSB motherboard? The only way to upgrade your chipset is to get a new motherboard. Peripheral buses[edit] Similar to the memory bus, the PCI and AGP buses can also be run asynchronously from the front-side bus. so i guess i can safely buy cheaper ram down to the lowest syncronous speed with no affect on performance if i don't plan on ocing or upgrading in the future.

Iv decided on a new mobo since the mobo it comes with only has a max of 1gig ram. extra bonus for listing the differences between intel and amd too So thanks prototyped. The potential of a faster CPU is wasted if it cannot fetch instructions and data as quickly as it can execute them. but 333 is listed against 800/533/400 fsb processors.

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. I have been happy with the popular DDR400 latency of 2.5.Use the memory finder tool at a major memory mfg website like Crucial.com to find the proper type and module size. Increasing the front-side bus to 450MHz in most cases also means running the memory at 450MHz. http://www.tomshardware.com/forum/57162-28-putting-800mhz-processor-533mhz-board Prototyped Ars Legatus Legionis Tribus: Slummin' it in London Registered: Jan 23, 2000Posts: 11083 Posted: Wed Dec 05, 2007 12:17 am quote:I'd suggest that (at default clocking) the 533MHz DRAM bus

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? e.g.:@100FSB divider will be 1/3 so [email protected] divider will be 1/4 so again [email protected], needs 1/6, but if board only has up to 1/4 your PCI bus would be running at 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). as i saw in your table above, 735 would indicate DDR800 speeds with a 4200+, but it's set at 667...

This design represented a performance improvement over the single system bus designs of the previous decades, but sometimes is still called the "system bus". Otherwise the system wont boot. This cpu, however, should work with it. the mobo currently i am using is 865 GBF original.

That is definitely bookmarked permanently.

Change it to the maximum bus your motherboard can handle i.e 533 or 800. Each transfer is 64 bits. Thank you.

Please help me!:horrified Agent_2406-04-2010, 12:30 PMProbably the multiplier is set wrong.

If it does it will only operate at 1.6GHz (I think).You may be able to overclock your FSB up to speed if you have pc3200 (or higher) RAM and the right 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 Will the 800MHZ fsb just operate at 400MHZ?

Discussion in 'Asus' started by BikeSv3000, Dec 24, 2003. If your motherboard is old and is restricted to 533 bus the P4 800 will not work at 2.6 Check your bus speed mate, if it says 400 it means it This RAM has a clock rate of 266 MHz and transfers twice a clock cycle. far too confusing for google.

However, the "memory standard" is DDR2-800. So which does the motherboard support? 1066/1333 RAM or 800, or all of them? Ask a question and give support. The Inquirer.

Note that these numbers don't depend on how much data you can shove through the pipes (bandwidth), but rather the clock rate.The latency is a significant factor since the processor is These secondary system buses usually run at speeds derived from the front-side bus clock, but are not necessarily synchronized to it. So in a stock setup, you want to use a memory divider that gets you the closest to the rated clock speed of the memory without going over.

I am running PC2100 RAM at 100Mhz. Hope that helps... The faster the RAM speed the better. SolMiester06-04-2010, 12:31 PMYour FSB is set wrong by the sound of it, you will need to check with your motherboard manual to see how to set the CPU speeds correctly!

This factors in when overclocking these processors, which I will talk about later.)As it happens, AMD's processors are clocked at 100 MHz intervals between speed grades, so you have 1.6 GHz, I'm currently waiting for funds to buy a 1066 bus speed processor. Currently this is DDR2-800 for current "K8" generation Athlons.
