k, i'm gonna build (with the help of some m8s) a new pc. but a few things i'd like to clear up:
1. Is DDR twice as fast as PC133?
2. What is RAID (i'm gonna get a Gigabyte 7DXR (hopefully) and it says I/O 2x UDMA ATA100 IDE RAID connectors for RAID 0 and RAID 1. 2x UDMA ATA66/100 bus master IDE ports on board. what does this mean?)
3. Does the 1.2Ghz AMD Athlon out clock the 1.4Ghz Pentium IV?
4. Where can i get a 15k rpm hard drive, and about how much will one cost?
ne help is much appreciated,
thanx!
Hello
1. No-DDRr(double data rate) is only about 10-20 percent faster than PC133 from what i have read. It depends on the application.
2. Raid-Random Array of Independant Disks(i think thats right) is a platform developed for sevrers to keep multiple copys of data flowing through the server in case a drive goes down, another will have the exact same data. In home systems, Raid 0 is a way to split up the read/write times to the hard drive(s). It requires 2 exact drives setup to act as 1(raid0). While drive 1 is seaking info, drive 2 is reading thus taking half as much time. The drawback is if 1 drive fails, you loose 1/2 of everything thus rendering all data lost. The 2x is two connectors for onboard for UDMA ATA100-the latest high speep data transfer mode(earlier mb's did not have it and a special pci card was needed to translate for the high data rate transfer to work. The same goes for the ATA66/100 ide support, its already built in.
3. Probably-Athlons clock speed is actually slower, but usually run a little faster in benchmark tests, hotter(need special AMD approved heat sink/fans) and according to some, are less stable and harder to get running correctly.
4. IBM and Segate-the last price i saw for a Segate 18gig 15,000 rpm drive was $550.00 and for a raid0 you need 2.
So DDR will give you a boost in speed during games,data manipulation and other memory intensive processes. The UDMA ATA 100 drives gain a small amount of speed during access, the raid0 configuration gains some speed again during disk access.
I take it from your question you want to build the fastest possible computer no matter what the cost. Hope this helps. Let us know what you build and how it turns out.
most definitely! thanx, last bit to this then, for the raid do i need 2 identical harddrives, or can i just have one? i don't really wanna have to shell out more money, and my puter is costing about £550 without a monitor (otherwise i would have had only £450 to spend cos of the price but i'm getting my families old one for free =))
Yes, I'm absolutely positive. RAID requires at least two hard drives. It doesn't matter how big one of them is. A RAID configuration requires more than one of them. The link you posted just shows specs for the motherboard which says that the board supports RAID configurations so you don't need to purchase a special adapter card. If you choose to go with RAID, that means even if you purchase two 80GB hard drives, your total hard drive space available will only be 80GB. You're buying the extra drive only to increase data access speed, not to double your capacity.
k, thanx. I'm gonna have a phone call to place 2moro morning, a bit of grovelling may be in order. thanx for all the info, no doubt i'll be back with more queries, lol.
I got it wrong-Raid(Redundant Array of Independant Disks) read more here: http://www.webopedia.com/TERM/R/RAID.html
The basic system you listed should be speedy enough for most anything.
The motherboard that you have a link to supports IDE RAID not SCSI RAID. If you wanted to implement RAID using SCSI drives, you would need to purchase a SCSI RAID controller card which will cost you several hundred dollars.
and in the end u end up slowing it back to IDE speed becasue of the PCI slot so its a bit of a catch 22
the athlon is faster then the pentium at slower clock speeds, not really enough to tell without running tests but for the price its good, they are reliable and use the best parts on the market.
i have an article if anyone would like me to post it again
YO why raid have seen many problems with raid not being set right, If you just want fast and have spending limits heres a few suggestions
1) Abit kt 7 E about 90 us
2)some pc 160 sd ram many brands
3)1.2 amd cpu under 125 usd
4) good 10,000 hard drive
5) video card these you can spend a lot on$$$$$(this important to gamers)
6) sound card
7) modem
8) atx case
Then of course you'll need awesome cpu cooler
then over clock rock n roll !!
You pay for speed
figure out how much you need then build to meet your needs
theres alot of dual cpu boards to
How fast = how much$$$ no pound key
And in 6 months will need to do again
its so easy to want more mhz
I'm just trying to make a point
Have fun read lots choose carefully
Steve
oh and just quickly, paul mentioned that DDR RAM is only 10-20% faster then SD RAM well i think what he means is the FSB, and techincly it is twice as fast being 266mhz and normal SD RAM is 133, although wouldnt perform twice as fast i woudlnt think. but there is deffinatly noticeble difference
Yes the FSB is 266 thus it is twice as fast in that aspect. What i ment was that from what i read, dont expect the machine to do tasks such as saving data or loading pages twice as fast. From what i read before building my machine, you can expect the 10-20 percent when all other variables are the same. This was from various bits of info i gathered while researching my last project. DDR is better, its what i used and i am HAPPY!!!
Thanx for all the help i recieved from u peeps. It was most helpful plus i managed to get my order from eclipse computers changed for free =) plus save £15 =))
