RAM Overclock
Memory clocks are run from a couple of different variables including frequency (1066) timing (5-5-5-12) voltage (2.1v) and whether or not you want to sync your memory divider with your CPU (1:1)
If you're missing options, in your mobo bios, I believe OC features are located in Jumper Free Configuration. Set OC to manual, not AiNos, and more options should be available.
Especially if you're having problems, you're going to have to do things sequentially. Good overclocking takes a long time, especially if you want to reduce the risk of burning out components.
Two tests you can use are
Super Pi and
Memtest86 You'll need a Floppy disc or Bootable CD to run Memtest86.
Drop your Hypertransport bus back down to 200, and reset your Memory Divider to 1:1 (Usually "AUTO") Leave your CPU Multiplier at 9x (For a 10 Stock Multi) and let start out at 215 at Stock Timings, Bump VDimm up +.1Volt) Run 5 Passes of Memtest86, then boot into Windows and Run SuperPi. You won’t be fast, but Super Pi runs a LOT of numbers through your Memory.
If all goes well, go up 5 MHz at a time until one starts to error. Then you need to start loosening the timings.
Go up 1 on CAS Latency, 1 on RAS to CAS Delay, 1 on RAS Precharge, and 2 on Cycle Time (Tras) and Repeat these tests. Depending on your memory, you may want to loosen them more. Just based on manufacturing variances, chips of the same type will be able to reach different levels. It's also a toss up between choosing frequency over timings, especially since you're probably not maxing out your memory bandwidth anyway.
Also, be very careful about how much you pump up your RAM voltage. Too much and you'll fry it.
From Extremeoverclocking.com since I'm not as familiar with AMD.
Once you've found your Memory’s max speed, this is where we need to do some math. Most likely there’s a sizeable gap between what your CPU can do and what your Memory can do. That’s OK.... That’s why we went down a Notch or 2 on our CPU Multiplier testing.
Lets say your CPU went to 260 Stable with a 1x drop in your Multi, Not bad.... a 340Mhz O/C on a stock 2Ghz chip... but your memory only went to 230 before you had to go to slow in your Timings. That’s OK.... Drop the HTT down to 230 and bring your Multiplier back to stock speed (10 xs in our example) you should have a Rock Solid 300Mhz overclock on your hands.
If the Gap between your Memory and CPU is so high, you can’t get to your Max CPU Speed with your Stock Multiplier, we may need to run a higher Divider on our Memory.
If we're talking 30+ MHz base difference.... You should probably drop your Memory Divider down to 166 and use your Max CPU Speed we figured out. Less than 30 MHz and you'll probably get better performance running 1:1 at your Memory speed. I say this because we'll be losing memory speed at our best settings at that point. Only use a Higher Divider IF your CPU speed will bring your Memory speed to within 2-5 MHz of your MAX Memory Speed. 240HTT X10 = 2400Mhz, Divided By 11 (166) brings out Memory down to 218Mhz If out MAX speed as 236, we're Giving away Memory bandwidth for no reason. However, if your Max CPU bus is 260, then we get this 260x10 = 2600 /11 = 236.
