Ram Ratio question...

After searching on the internet for a while (ok I'll admit - 5 mins max) I decided it would be faster to ask the hardware guru's here...

What does the Ram Ratio setting control?

Also, since I'm asking noob questions I might as well get them all out of my system 🙂

What is the difference between RAID and SATA?

Thanks and please be gentle on any rude comments about my hardware knowledge. 🙂
 
SATA is SerialATA. It's a different type of interface for HD that provides up to 150MB/s of data transfer, as compared to PATA at 133MB/s. It doesn't actually constantly sustain 150MB/s, but it's a nice solution between IDE and SCSI.

RAID stands for Redundant Array of Inexpensive Disks. The most common type of array for majority of home PC users would be RAID 0. A RAID 0 setup turns multiple hard drives into one, essentially. For example, a RAID 0 array of 2 40GB drives would show as 1 80GB drive. A RAID 0 array splits the storage and data access between the two drives, giving a performance increase by reducing seek/load time from the HD(s) to memory.

And I can't answer your RAM question, so I'll just start to look pretty and whistle now 😉
 
ok after a slightly more extensive search of the internet (about 6 mins. hehe!) i came up the following definition of ram ratio. ram ratio or memory frequency ratio determines if the memory clock frequency is synchronous or asynchronous with respect to the system frequency (a.k.a. FSB or CPU bus). 1:1 means synchronous, and all other settings are asynchronous. common ratios are but not limited to, 3:4, 4:3, and 4:5. for instance, if the ratio was set to 4:5 with a CPU Frequency of 133 MHz, the resulting RAM Frequency would be 166 MHz. (133 multiplied by 5, all divided by 4). it's advised you keep the CPU Frequency: ram frequency ratio to a 1:1 ratio.
 
Just 1 more minute of searching and I'd have found it! 🙂 Great thanks for the info both of you. Two quick questions... 1st about the RAID setup.. so if I have just 1 HD that is 120 gig the RAID setup is useless to me? Its only if you have multiple HD's?

And 2nd question: Regarding the ratio - is the 1st number always the CPU freq. and the second RAM? Thanks~!
 
Yes, RAID is only applicable to multiple hard drives. It is STRONGLY advised that the hard drives are as identical as possible, also, although it is not necessarily *required*. The best performance increase/stability/use of a RAID is achieved by using multiple drives of the exact same type (IE buy them 2 or 3 at a time)
 
just look up raid on google, there are many modes depending on what you want. sheer speed? or data protection.
