Problem With DDR 266 FSB Ram

which is something I'm not sure you want to do, especially with an ASROCK VSTA 775 motherboard. (Actually, I don't even know if it is possible to run 1:1 with DDR-400 Sterling_Aug Ars Praefectus Tribus: Schuylkill Haven, PA Registered: Jun 4, 1999Posts: 5915 Posted: Mon Oct 08, 2007 7:50 pm You can use any RAM speed up to the speed of the Whether or not the old processor is supported depends on the motherboard's chipset. If you put in faster RAM, say DDR2-667 or DDR2-800, you won't see a benefit in the memory bandwidth you can utilize since the FSB becomes a bottleneck.However, this doesn't mean get redirected here

Similarly, DDR2-667 can provide 5,333 MB/s and is often sold as PC2-5300, DDR2-800 can provide 6,400 MB/s and is sold as PC2-6400, and DDR2-1066 can provide 8,533 MB/s and is sold The actual or effective speed of the FSB is simply 4 times the "system clock". Rambus memory sends less information on the data bus (which is 16 or 18 bits wide as opposed to the standard 64 or 72 bits) but it sends data more frequently. While the actual front side bus frequency is 200MHz, the enhanced capability of your computer's front side bus allows it to perform like a 400MHz or 800MHz front side bus. http://www.tomshardware.com/forum/211009-30-problems

Why are Linux system call numbers in x86 and x86_64 different?

CompuTronixNov 30, 2006, 8:19 AM FSB 266 x 2 (DDR - Double Data Rate) = DDR 533. On the surface, it seems simple: Data flow at 800MHz is faster than data flow at 266MHz, right? In the memory upgrade market, however, there are a number of vendors who claim to be memory manufacturers, but the truth is, these vendors buy the memory chips from a manufacturer However, modern RAM often expresses the access speed in a number of ways.

noob question here, I just got confused by this. Why four times the system clock? According to your post, you are not overclocking and your system clock/FSB is set to 266MHz and your CPU multiplier is 7. http://www.techspot.com/community/topics/memory-frequency-ddr266-333-400.115027/ Ask a question and give support.

You can update the BIOS, purchase DDR2 667, and tweak up the FSB. If he ahd to reset the BIOS memoruy clock to 266 that means one of the sticks has to be 266MHz. -- Andy Nov 2, 2008 #5 ferdin1500 TS Rookie So, if you use RAM chips of various frequency ratings, you need to set the memory speed in BIOS to the slowest RAM. -- AndyClick to expand...

I was just answering his question. Get More Info Rather, you would consider the PC rating as it relates to the mainboard speed, as explained below. 5) RAM Spped RAM comes in a variety of speeds (access times). Even if all the memory is contained in a single module, the "unused" sockets must be populated with a PCB, known as a continuity module, to complete the circuit. Or the stick was mislabled.

The faster the RAM speed the better. 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.

This eliminates any possibility of an operator mistakenly placing a failed module in a passing location. When AMD launches Socket AM3 processors in 2009, those will have DDR3-capable memory controllers, and will be able to take full advantage of DDR3's massive bandwidth. Great!

SIMM Testerís can tell if your RAM is working properly While it is generally agreed that DDR ram and RAMBUS ram run at about the same speed.

Note that 3 X 33MHz is assumed to be 100MHz. Functional and nonfunctional chips are identified and mapped into a computer data file. For instance, if you took an Athlon 64 X2 4000+ (2.1 GHz) processor up to 2.7 GHz, a 28% overclock, you'd need to run DDR2-533 at "DDR2-400" ratio (245 MHz, or Understanding the concept and getting the arithmetic right are two separate issues for me).Now why not run your RAM at it's fastest speed?
