Help me overclock my RAM on AMD platform.

post #1 of 7
Thread Starter 
I have heard from many people that it is possible to overclock ram to 1866 with phenom quad core processor. I can only get mine overclocked to 1720MHz at the most and sometimes it doesn't even work. What do I have to do to get it that high. My motherboard supports up to 2133 and my ram supports up to 2000MHz. I have the ram set at 1600MHz and the bus speed up to 215 which brings my ram up to 1720MHz. If I go 216 on the FSB it wont work. I've tried raising voltages but I'm afraid to go to high even though my motherboard can probably support it. Im affraid to fry my processor. Should I set the ram at 1333MHz and put the bus up to like 260-270 or so.

When I first built the system the ram was set at 1066MHz. Should I start from here and overclock? If I do this its seems that I would have to set the FSB really high to get the ram at 1866 or higher.

Let me know if anyone has overclocked their ram to 1866 or higher with a phenom x4 965 be or similar. Or if it's even possible. I have tons of cooling and non of that is a problem. I've overclocked my CPU up to 4.3GHz and it wont get close to 50C.

Please let me know what you think and if you have any suggestions.

Also, I know that the bulldozer is coming out soon and I would like to know if it will be able to support 1866, 2000, or 2133MHz overclock ram speeds. My motherboard supports all these frequencies.

Any suggestions are greatly appreciated.

Thank you.

Right now they are 11-11-11-42. I am not sure about the last one but the first 3 timings are correct. I heard that for AMD platforms that higher timings really dont make a difference.

you didn't hear right i think but let's try with 11-11-11 and when you reach higher speed than you will drop your timings...
now put 1.65v or 1.7v to ram... (dont worry it's safe)

My timings are basically all the way up that my motherboard will let me. I can get as far as 1720MHz with the FSB at 215. If I jump the FSB up to 216 it becomes unstable. Do you know what kind of voltages I can reach without blowing up my cpu or board?

Lower your ratio and raise the fsb
what is your core speed at?

Another thing to do also is set your HT link at 2000 or 2400
and NB at 3000 should help out some what

how much ram do you have installed?

My CPU clock speed is 4.0GHz and I have very much flexiblity with that. I've had it at 4.4GHz with only increasing the voltage a few increments and not reaching temperatures above 48.0C.

I have 8GB total memory installed.

If I increase the FSB and the NB to 3000MHz with the RAM set at 1600MHz the memory speed will be increased well over 2200MHz. With the RAM set at 1600Mhz I am unable to set the FSB higher than 215 which sets my RAM at 1720Mhz.

If I set the RAM at 1333MHz and increase the FSB to 300 the memory speed will be around 2000Mhz (I think I have tried less than this with RAM set at 1333Mhz and it did not work). If I set the RAM at 1066MHz and increase the FSB to 300 the memory speed should be somewhere around 1866MHz.

When I first built the system and turned it on and went into the BIOS it had the RAM set at 1066MHz default.

The RAM's manufacturer's SPD is 1333MHz.

Should overclock the RAM with it being set at 1066MHz which is BIOS's default setting or should I overclock it from 1333MHz which is the RAM manufacturer's SPD?

Thank you for your help and your time.
