RAM Dividers

post #1 of 9
Thread Starter 
Ok guys I have an ASUS A8N SLI Delux MoBo The terminology is way different from my last on almost all the BIOS OCing features from my Chaintech I had last time. There is nothing that says anything about 1:1 or 1:2 or anything even remotly resembling it for RAM. Can anyone tell me how to set my dividers on this board?

I am also having Vcore stability problems. on CPUz it says it is fluctuating from 1.376 to 1.424. My 12v rail doesnt fluctuate at all but stays at 11.71 wich is within tolerances. My PSU is an extreemly stable PC Power and Cooling SLI edition that says there is a precision voltage tweeker. It didnt have any software with it and I dont see any obvious way to tweek the voltage. Anyone know how to tweek it so I can put all my outputs at Exactly whatb they should be?

The Vcore is controlled by the MB and these are known to vary alittle, its an Asus thing. Also the Voltages being reported via SW - PC Probe, will likely not be accurate and indeed you have a very good PSU. The only sure way to check is to use a multi-meter and test the rails under Post, OS Idle and OS LOad to see if there is any difference. There are vairable POTs inside the PSU but to access these you will void your warranty, it should be unlikely that the PSU needs any adjustment.

With regards to the Mem and dividers, you are right, the Asus do it a little different. MaxMem is used as the divider 200, 166, 133, 100 but you also need to set other options in the BIOS to take real control.

Have aread and work through the FAQ on the A8N MB - see link in my sig.

If you want to relate the ratios to the mhz:
200= 1:1
166= 3:4
133= 2:3
100= 1:3
I am pretty sure thats how it goes, someone please correct me if i'm wrong.
**edit, fixed the 4:3, thats supposed to be 3:4

you're wrong... 166 isn't 4:3 because that'd be i think 266.

The first 2 on your list are correct, but the next to you have reversed, should be

133= 3:2
100= 3:1

FSB (HTT in AMD terms i think) : DRAM is the ratio

I'm not sure specifically about the numbers, but the A8N-SLI Deluxe uses the dual data rate speeds so it would be:

400 - 1:1
333 - 4:3
266 - 2:3
200 - 1:3

well if the nubmers are right that should be the way it looks in the bios. I haven't had very good luck w/ running dividors on my board so I'm not all that familar w/ them.
