OverClocking FSB on AM3 makes ram need more Voltage. Why ?

post #1 of 3
Thread Starter 
first of all, I dont care about high frecuencies, all i mind is as highest as possible fsb, but each time i overclock fsb and reduce core multiplier and ram multiplier, to minimal settings, i still need extra voltage to make it stable (ram voltage). So i dont understand this, why my memory needs so much voltage otherwise it fails memtest86. I know they are not the best sticks, but if i can solve this issue without changing hardware i could get higher fsb, anyway since i dont understand why this happens i need your answers, did search google and cant find much. sorry to bother you guys, thanks (:

and this is my hardware:

cpu:
Athlon II X3 455

motherboard:
M4A87TD/USB3

memory:

2 X 4gb common kingston memories


ps: memories under no overclock pass many times mem86, cpu runs hours OCCT , same for Prime95

Maybe the RAM doesn't like running so far under its rated specs. Maybe your timings are auto'ing to something weird at whatever speed you are setting to and requires more voltage to be stable. Maybe it is the memory controller you are adding voltage to, not the memory. Maybe some parts of the RAM are tied directly to the FSB.
Not really a lot of into in your post to go off of here.

ram is not running on higher Mhzs since ram multi is at mininum.

timings are set manually to 10-10-10-27 usually they are 9-9-9-27 on stock

im not touching cpu memory controller voltage

"Maybe some parts of the RAM are tied directly to the FSB." not sure what you mean by this

ask for any info. anyway everything is normal or stock except what ive already mentioned i changed.( overclocked cpu fsb and underclocked cpu multy and ram multy)

thanks.
