Overclocking DDR Dual Channel Ram

The first thing I suggest is downloading Memtest. Have it on your computer even if it's not already installed on your BIOS. If it is on your BIOS I suggest just using the pre installed one even if it is not the newest edition. This just saves some time and frustration.

First find out how much voltage your RAM will take. Components these days can handle a little extra voltage load. If you are scared just place the voltage at the maximum the warranty supports. If you get one error before the 3rd Memtest than reboot and adjust your voltage lower. The 3rd test seems to expose any immediate instability in your system. Just waiting until the 3rd test is again going to save a lot of time and frustration. My objective here is avoid ever having to reset the CMOS as this can be a pain when overclocking anything for that matter. I have active cooling over my RAM and you may not but it is certainly worth it. It will allow for higher voltage, meaning higher clocks, and longer memory life. Pay attention to your warranty as high voltage RAM a lot of times needs active cooling to be supported under warranty.

Now adjust your timings one lower at a time, they seem to be much more important than bandwidth. Run Memtest after each movement until after the 3rd test. If you get one error set your timings back to the last working configuration. If you do fail a test work on the other timings. I do not know which timings are going to improve your speeds the most, but if you do a little research on the topic you can find out. Adjust the settings that improve Memtest speeds the most first.

After you find the lowest timings you can get at the highest voltage you do not get errors at move on the bandwidth. This may be where you gain a lot of computing speed depending on a lot of factors including mostly: your RAM, your CPU, or your chipset. Always leave your CPU overclock at the highest maximum as this improves computing speed the most. Adjust your ratio faster one at a time. Run Memtest after each movement to see if you are getting errors after the 3rd test runs. After you find your maximum timings and bandwidth go ahead and run Memtest for the entire test. You probably will not see any errors since Memtest will catch most of them after the 3rd test. If you do run into an error adjust your settings a little lower as you go through this guide again.

Now you should be getting all your money out of your RAM.

Doing this method got me 1-0-0-0 timings at 210mhz giving 4 sticks of DDR Dual Channel (512MB sticks) 4 volts. This is incredible to me as the RAM is only advertised as 2-2-2-8, 200mhz at 3.2v. I do understand my voltages are high, but with active cooling I'm totally fine and stable.

I'm telling ya. Those numbers are for real, I'm actually still blown away. Real world it's not that much faster.
 
this guy has to be trolling. first there is already a guide on this (in the cpu and overclocking section), and second 4v probably isnt even SUPPORTED on most boards for ram, since anything much above the ram's spec should probably kill it instantly. 3rd, 0 latency should be impossible, since then your DRAM would be running faster than SRAM, which is impossible. i would like to see a link to the kit being used. the voltages listed here seem insane, even for old DDR.
 
I'm no engineer but I have not yet seen how memory can be written to, read from, refreshed, etc etc in 0 clock cycles? 😕
 
Those timings aren't actually possible...likely you are running the same timings but the board is reporting them lower.

What mobo are you using...because it's fooling you.

Memtest reports the same numbers. Does screenshot work in Memtest? You could be right.

I don't know anything about that whole SRAM/DRAM thing. Just reporting the speeds I got.
