Quick RAM Question........

If you tighten up your timings on the RAM but not change the frequency, do you SOMETIMES have to add more voltage to the RAM to make it stable? Like would it require it sometimes?

any increase in performance, whether it be faster speed, or tighter timings, may require a *different* voltage... most ram has an optimum voltage depending on the modules... so for winbond stuff that could be 3.2-3.6v... for tccd 2.55-3.0v... uccc 2.6-2.9... etc

 

usually the faster/tighter, the higher end of the range is needed... but you need to understand that it's not like you can keep increasing the voltage and get better results for ALL ram... some tccd for example runs best at 2.6v, and higher volts is detrimental to the stability... but at the same time, some tccd (like my gskill LE) runs best at 2.85-2.95v

 

this is why running extensive oc scenarios for ram settings on memtest86+ at borderline stability is important to find out where the optimum voltage values lie for your ram... decrease it until you get errors, then increase it til you don't, then increase it more until you do again... increase the speed or tighten the timings to create more errors if needed... the voltage with the *least* errors like say you get 10 errors on test#5 1st pass, then 24 on the 2nd pass of test#5 at a particular voltage, but any other voltage you get *more* errors than 10,24... *that* particular voltage will be the best when you bring the speed down and adjust the voltage to where it is stable :)

 

the key is experimentation (lots of different settings), recording error results in tables, and patience...
