What is my CPU Voltage? Also, Where's the FSB?

[Down8]

What would you place your money on here?

Allowing for a second of refresh-variance, these items could be a little different. But, I'm not even sure which one is worth looking at. (Granted, just picking one and using it as a baseline to undervolt/OC, would be workable, but still....) CPU-Z and HWiNFO are showing the same number, so maybe that one?

If it matters, A-Tune is set at:
Vcore Voltage (Offset) -0.065 V [was running OK @ 5P/4E-GHz/-0.090, but settled here for 5.1P/3.9E-GHz]
VDD_CPU Voltage 1.386 V [this is one click down from the 1.396 default]

Secondarily, does no one mess with what I would call the FSB (front side bus) anymore? Is everything multipliers now? My first OC was just taking my P3e from 5x100 to 5x133 (and eventually 5x140), and I've been out of the game since my Q9550 @ 8.5*400 (vs. stock 333 FSB). Does messing with the clock even touch the RAM these days? It was integral back then to have supportive RAM, but does XMP override all of that? (Feel free to chime in, but parallel with posting this, I ran across this thread, which had some useful insight.) It seems it more or less went away with the Northbridge/Southbridge changes. But even so, is the 100MHz base clock worth screwing with? If I moved it to 101MHz, would my RAM notice? Would anything outside the CPU notice?

Edit: related sidenote - man, what a downhill slide. From a 40% OC, to 20%, to now not even 5% (10% would be amazing!). They're letting less and less of the 'free' juice out of the silicon.

having a bunch of monitor tools running can throw things off as they are all poling at the same time. id just go with hwinfo.
no, no one really uses fsb ocing anymore. it was mostly for multiplier locked chips anyways.

Bclk fiddling is long done with. You can move it a few MHz without screwing much up and your memory will change with it. Sometimes better, sometimes worse, depending on target memory frequency. Lots of things, including PCIe, are based on that frequency and can go haywire or outright fail if it's too far off. A few special B chipset boards were made with independent timers to get around this limitation, but aren't worth it.

Overclocking back in the day was such a good time. My first build was a Celeron 333mhz slot 1 cpu with a ASUS P3B-F motherboard. Had to change out my NIC to get my whole system stable at the odd in between FSB. Sure got my fps up in Quake, woo wee!

At OP:
Your VCore ranging from 1.29v to 1.312v (correctly read by CPUID, HWMonitor, and HWInfo at VCore).
The FSB is BCLK frequency stated on your ASRock A-Tuning or you can search at HWInfo with sub--> Bus Clock.
