AOpen ax4sg-un RAM question

post #1 of 6
Thread Starter 
actually its a ram based overclock question
so i have 2x ddr400 and a ddr333 (i remove this when i test oc's)
and im inside my bios and i have a pretty impressive overclock on my processor
my ram timings are 3-4-4-8 but, i cannot seem to find my ram:fsb ratio.. does anyone else have this problem and/or know how to correct it? i mean my computer is running stable as it is and i dont even know what the ram:fsb is but i hear to reach higher fsb's i have to have a 1:1 which is why i want to find it and increase my fsb from like 664.7 or something

my motherboard

i dunno if that will helP :S

There is no setting for your FSB:RAM ratio. That is just a measurment of 2 different settings.

You set your FSB and RAM seperatly, how they relate to each other is the ratio.

Find the setting in your BIOS to set RAM freq and set it for a Mhz setting 2 times the FSB in your CPU settings. So if your CPU is at 250 FSB, you want your RAM to be set at 500Mhz.

That is 1:1.

yea jucs checked and fsb is like 680mhz
and here are all my goodies

for my ram it is set on auto clock o.o
if it isnt it only has 2 other options

DDR bus -164xauto=ddr410
164x2.50=ddr410
164x2.00=ddr3.28

AGP bus - 164/2.46=66.67mhz
(goes up to about 98.68mhz)

CPU - 166x23.00=3.8223Ghz


**VOLTAGES**

CPU ->1.5V (changed from 1.1 started there and increases by .025 up to 1.5875V)
AGP ->1.6V (changed from 1.5V)
DDR ->2.7V (changed from 2.6V)

that all u need?

Sorry, work has been heck.


Ok, so with a FSB of 680, that means your setting your FSB in BIOS to 170 (170x4=680), which means for 1:1 you want to set your RAM to run at 340Mhz (170x2=340, RAM is only doubled)

So you are saying in BIOS, you can only select AUTO for your RAM speed? Or those other 2 settings? Well, your board doesn't seem overclock friendly. If you only have those choices, I would try the 328 setting, as this is closest to the 340 target and should allow you a more stable OC.


Also, you should set your AGP to 66 IIRC and lock it there.
