Here are a couple more pics just in case they are needed...
Please help a noob with a memory overclock
I have taken my little e4300 about as far as i am comfortable with. 3.1Ghz with a voltage setting of 1.3625 and prime95 temps of 67c after an hour. (coretemp's VID says 1.325v, i guess this is vdroop i am seeing here?) Anyway, i would like to start on my memory overclock now that i have gone as far as i can with the CPU. This is the overclock method that i have learned from countless hours of reading forums and guides. Well, here is a pic of my bios with the memory settings that i currently have set up, please tell me if there is anything you would change in order to overclock the memory better/further.
As you can see, i pretty much have it set to the stock settings of typical 1066 memory. (although the memory is currently only running at 1026 or something like that, it changed when i upped my CPU by 100Mhz) Is there anything that i can improve here? I am afraid i am not sure what all those settings are at the bottom under **ADVANCED MEMORY SETTINGS** The top i have set to 5,5,5,15 (with a CMD of 2T, i guess that mean 2 commands per clock) and the bottom is set to:
tRRD: [Auto] - 4
tRC: [Auto] - 30
tWR: [Auto] - 6
tWTR: [Auto] - 10
tREF: [Auto] - 7.8uS
From what i have read, the 30 in the tRC field needs to come down to about 24, correct? Also, if you see anything else or have any other suggestions, i would be happy to hear them. Thanks- Benny

Thanks man, that explanation really helped me out a lot.

But yeah i do find it to be kind of a pain in the rump, to not be able to set my FSB:Memory ratio even with it set to "Unlinked".

Change your avatar before it shoop da oops all over your memory controller or something

Most people think its odd that the mobo will just pick its own ratios, but it really does give you more options for OC'ing the RAM. Unlike intel chipsets which are limited to just a few ratios the nvidia are almost unlimited. I think im running 5:13 at the moment.

I think a lot of people dwell on the "magic" 1:1 ratio. My advice dont. Just find the highest speed you can run the RAM at, and most of the time that will give you the best performance.
Yes there is a little more to OC'ing RAM then the CPU, but thats just part of the fun.

My next question would be, is the fact that i can't control my divider going to hurt my overclocking ability? I mean i can, but then everything gets set to auto and i lose all of my memory settings/overclock. I looked at my FSB:Memory ratio and it has it set to 5:7. I have heard before that 1:1 is the most desirable for overclocking purposes due to it yielding the most performance. Any truth to this? I have learned one thing though, there is a lot more to overclocking RAM then there is to OC'ing a CPU lol. |

Most of the numbers dont need to be the same, and like you already guessed to get the most out of the RAM they probably wont be the same. For example I have run RAM at 4-3-3-9, 5-4-4-12 and 5-4-5-18 and they were stable. Probably the most important performance settings are tCL, tRCD, tRAS, and tRC.
The only two I am aware there is some type of formula for are tRC and tRAS. These formulas are to figure out the absolute lowest you can go.
tRC= tRAS+tRP
tRAS= tCL+tRCD+2
I was the one who mentioned that messing with timings can corrupt your OS. Which is why I always recommend testing with Memtest before booting up the PC.
Good luck and try not to brick your PC.

Or some people do 4-4-4-12. Well it occurs to me that 5+5+5=15 and 4+4+4=12. What if you threw a different number in there like: 4-5-5-15 or 4-3-4-12? Would that screw anything up? This is something i think i will have to do in order to find the lowest timings that i can run. And someone made a comment about the TRC being able to corrupt your OS so i was afraid to go playing around with the timings to much without asking first. |

It also seems to me that there is a bit of a balancing act going on. Cause i would love to run my RAM at 1200Mhz, with timings of 4-4-4-12 and a tRC of 17. But that's not going to happen, is it?

Still, as an overclocker, i have to try...
