I keep seeing threads that say that the 8rda will not do over 200 fsb without volt mods,however this is not true.It may be that my mobo is a later model that was received 03-06-03.It has a1 marking on the northbridge and the a3 on the southbridge.I was hoping to just get 200 fsb as i had ordered pc 3200 twinmoss ram and was quite underwhelmed when it posted and ran at my first attempt of 200 fsb sync.
As per alot of post i upped the v-dimm to 2.7 and the v-core to 1.650 and tested different ram timings.It soon hit it's limit of 215 without entering windows so i fugure i will run it at 205 with 7-3-3-2 timings(this ram timing scored better than any other with my twinmoss)
Later it occured to me that the reported voltages must be inaccurate as the 5 volt line shows less than 5 volts and the 450 watt psu had shown well over 5 volts on my previous kt7a-r.One of the reasons i had gotten the 450 was my 5 volt line was under 5 volts with my previous psu and voltages seemed not so stable.I was also seeing more heat from my cpu than i had previosly so it occured to me that many of the readouts might be reporting lower voltages than they were.
The only way to test my theory without a voltmeter(lates just say the one i had met it's fate in a brilliant flash of light)was to go into the bios and reset voltages to default and retest.Not only did it boot but got into widows at 215.I run raid so i don't like extreme speeds that arent 100% stable,so i backed her back down to 205 and she runs fine.My usdm reported voltages are,
VDD: 1.568
v-core 1.616
vdimm 2.608
+5 volt 4.945
+12 12.342
My 2100's limit had been previously established around 2050 and would do this at 1.68 and it wouldn't boot with less voltage according to via's hardware monitor.Very unscientific,but perhaps volt modding is no longer neccessary with newer boards which is contrary to what i have been reading.
