With 4 modules, these timings are good:

 

CL: 5.0 clocks

tRCD: 5 clocks

tRP: 5 clocks

tRAS: 15 clocks

tRFC: 55 clocks

CR: 2T

 

 

Did you clear the CMOS or simply reset to defaults? If you did not do it, be sure to use the jumper as instructed in the manual and clear the CMOS.

 

Also, take a look HERE.

OK CMOS cleared and everything is reporting as it should...

 

Done the windows thingy... that worked but I actually found that article earlier tonight and tried it and it failed. Works now so that's all good!!

 

I'm going to report back once I've input the memory timings.

Everything's working fine.

 

Just one more question... previously the system was overclocked. Should I not overclock it as that could be the cause of my problem?

 

The system was overclocked for ages at 3.6 ghz on an Artic Freezer 7 solution. No problems. I put in my new sticks of RAM and it stayed overclocked fine using the same settings for 1 week then the BIOS reset itself. Now it will only go as high as 3.4 ghz without locking up on power on.

 

Just wondering if this is related at all.

Although the system might have been stable for a while at a certain speed overclocks can change and vary over time. If the machine is working ok at stock speeds I would leave it at the stock speeds if you feel the need to overclock you might have to find newer settings with a lower overall clock versus the previous overclock.

Hi All,

 

My motherboard is reporting my 4 sticks of RAM as 7424 MB. Doesn't sound right to me. Can anyone tell me if that's normal?

 

Thanks

 

You need to turn on memory hole remapping in your BIOS.

 

You're missing the IO mapped memory at the top of 32 bit addressable RAM.
