The default CPU/NB multiplier is 10x. If you've increased reference clock to 250 MHz, the new CPU/NB clock would be 10 times 250 MHz = 2'500 MHz.
Now, do keep in mind that, as most anything, the CPU/NB requires more voltage when overclocked.
If you didn't pump more voltage into it, it might've been responsible for your crashes. That's why, when overclocking, you try to keep everything the same except for the part you're tuning - so that there is only one source of error.
I realy can't find where to adjust the cpu multiplier in my bios for the M5A99X. If I brg my vcore voltage to 1.5, then there something that will make it even go higher by like .015-.025 its prolly a bios setting that I need to turn of so the voltage doesnt vary.
I have a 1050w psu, so I can allow myself to brg the voltage up, as well as a corsair 100h liquid cooling that keep the temp under 55c witch from what I saw is the max you want to keep ur pc stable on an 1100t.
Tryed to up the multiplier tru ai suite 2, and everytime I do so even if it barely by .5. From 16.5 to 17 and lower the fsb to like 200 from 248, I'll get a blue screen. So im sure off that its impossible for a M5A99X to adjust the multiplier.
