vcore fluctuating ALOT should i be worried? Overclocking help

post #1 of 6
Thread Starter 
I set my bios vcore to 1.46 to overclock my cpu to 3.8ghz because if i set vcore lower it hangs.

When i look at cpuz, vcore when running prime95 isn't anywhere near 1.46. It fluctuates 1.33 to 1.39. Is that to much of a fluctuation? Or should i bee fine?

I want to get my cpu up to 4ghz but the way things are going it seems i will have to set my vcore in my bios to an excess of 1.5 to get it stable. Would that be safe, and to keep that overclock as my new setup?

Temp while in prime95 for 3 hours was at a maxed 38C in core temp but seemed higher in the temperature located in my bios.

I never had an AMD cpu before, but if you have energy saving settings on, that would cause your vcore to fluctuate. While its idle your cpu would use less vcore, under heavy load your cpu uses more vcore. However, the amount of vcore your cpu uses under load should not be so much more than what you set it in the BIOS. Hope that helps.

Am, I rly dont get it, the stock for 1100t is 3,4 right? So turbo core should get it to 3,8?
I can get my 1090t to 3,6 stable with stock voltage, as its supposed to be underclocked from 3,6 to 3,2. And for 3,8 it just needs a 0,05v increase, so 1,375. For 4ghz I could post with 1,4 vcore, but it wouldnt make the Intel burn test, so I just reversed it, dont want much more voltage on this budget board I have.

Does the 1100t really need that much more power, you have to have some settings wrong I think, or the mb just doesnt support proper voltages.

P.S(Tried flashing a new bios for mb? If there is one ofc)

I don't get it either, i had a different asus board with the same processor and i need way less vcore to get it to a stable 4ghz. My old mobo had an 8pin cpu connector where this one has only a 4pin... I think that might be the reason, at idle vcore in cpuz is at 1.42 at load it goes down to 1.39-1.36.
Even though i set it at 1.46 in my bios

btw. i flashed it to the latest model, plus added the latest chipset

I am getting a different motherboard

For my 1090T for 3.6ghz overclock stable I need 1.3250 volts and 1.2500 volts on the northbridge for 2600mhz

CPU-Z and Aida64 both report 1.3280 volts when in windows, and max max MAX load like intel burn test reports 1.3380 or 1.3400 volts
