FSB:DRAM Ratio of 3:10, safe?

post #1 of 4
Thread Starter 

So im currently new on OCing and im still in the process of learning things. Ive read some stuff about the ratio of FSB:DRAM and most of the people were saying that its better to have a 1:1 ratio. In my case since ive OCed my system i wanna ask if my system is still safe with its current configuration with 3:10 as shown in the image above?

For additional information ive included my current set up.

Clock: 3.876Ghz (228 x 17)
DRAM Freq: 760.0 Mhz (BIOS DRAM Freq set to x6.66 coming from x8.00)
HT Link: 2052.1 Mhz
NB Frequency: 2052.0 <--- Set to Auto

Case: (White) NZXT Phantom Enthusiast Full Tower Case
Mobo: Gigabyte GA-890GPA-UD3H
CPU: AMD Phenom II x4 965 3.4Ghz (Black Edition)
CPU Cooler: Corsair H100 Liquid Cooler
RAM: Corsair XMS3 Dual Channel 1600 8GB 4x2GB
Vid Card: Sapphire HD 5850 Xtreme 1GB 256bit GDDR5
PSU: Antec True Power 750w
Hard Disk: Seagate 2x1TB (Storage) and 160GB (System)

I think the recommended 1:1 is for the intel crowd. I have had no trouble with different DRAM ratios. Actually my system puts me at a 1:2 stock and when i oc i have gone to 3:8. I think you are fine at 3:10 as long as its stable. Do a couple hours of memtest and test.

Also try to setup a sig rig so you dont have to copy paste your system specs everytime thumb.gif

Not only safe, but doesn't even matter.  AMD platforms since 2003 (Socket 754/939) and Intel platforms since 2008 (1366-15156) make use of integrated memory controllers onto the CPU that basically remove the need to have an even divider DRAM:FSB ratio anymore because any related latencies to having an uneven one are removed.  You can get the same performance with a 66:67 divider as you would with a 1:1 divider, approximately.  In fact DRAM:FSB isn't even the proper way to call it anymore because there is no FSB.

So that explains something. Thank you for the quick reply so far no errors has been reported after i ran prime95 for 5 hours though i had to set the NB Freq to auto as i kept on getting errors and BSOD when i adjusted its multiplier. I am running on 4.2Ghz now.289
