So base settings for the CPU are 200mhz, 16.5 multiplier, 1.2V
tl:dr Should I be increasing the base clock or the multiplier, does it matter if I only increase the multiplier? I know changing the base clock overclocks basically everything, so should I only be increasing the multiplier if I just want my CPU running faster?
however anything past 210mhz at the stock volts gives me this from windows, I've tried going to a 220mhz base with 1.2225V and the RAM on 800mhz base, with the north bridge at 2200mhz base(2400mhz being the max stock) The motherboard has pretty solid power delivery, but lacks some of the extra overclocking features of a higher end board naturally
So from there do I just keep upping the voltage until it's stable at a 220mhz base, or should I try bring the multiplier up first with a 200mhz base, going for 8350 levels which are 200/x20/1.3V, I'd imagine at minimum this would need extra voltage to get there at least
Never bothered learning how to OC, mostly going by jayz's old video, thanks for any help
Increase the multiplier first and foremost. If you want to be balancing RAM, HT, NB and CPU-NB timings than mess with the FSB. The multi increase is easier, and is preferred when available.
Bring your multi up one step at a time, testing each step for a few minutes with something like AIDA64 or even OCCT. Adjust voltage when needed, although it's pretty safe to just bump the FX voltage to 1.35v or 1.4v and overclock until it's unstable, then drop it down a step or two.
If you're wanting to OC both the FSB and multi, adjust HT, NB, and RAM voltage accordingly. They can handle the additional clockrate so long as the power is flowing. Adjust their clocks down a step if you plan to push higher than 210MHz though. (RAM excluded, you can just increase voltage to 1.65v max if needed.)
Ya going the multiplier route seems much easier and windows isn't giving me that issue anymore, I'm currently at 4.2ghz just over 1.3V and cinebench has completed, prime95 for a bit is next, seems like I got a decent 8300
and....crashed immediately on prime95...time for more voltage, I think this may be near the max actually, but not too bad for a near $100 CPU
although my CPU is at 100% for some reason in CPU-Z at least I'm at 4.2ghz with 1.3V after upping it to 1.35 ish in the BIOs, odd
Prime95 is not optimized for the CMT uarch in the FX chips, it causes voltage and current spikes as well as more severe vdroop. AIDA or OCCT are better, despite OCCT using a very similar stressing system.
Maximum load voltage for the almost every Bulldozer derived CPU is 1.55v. 1.5v should be a daily max, and 1.45v should be the absolute stability point to avoid any damage from prolonged use. (If you are worried about that.)
Ya, was going to stop at around 4.4-4.5ghz at 1.4V if it's stable enough
OCCT is dropping my voltage as well, and made my PC freeze, is it just even harder than prime95 or something? because that was on it's 3rd pass no problem
Also is keeping this thing running at 4.4ghz all the time going to increase idle power usage? Doesn't it normally downclock itself to whatever to save power?
I am running the following for two years now without any issues (though I never primed it or anything). I only changed the multiplier and left anything else as is. But no idea why cpu-z i showing it up to 22,5 times, as i never passes the 21 times @ 4,2GHz. The Idle downclock works fine, sits at 1,4Ghz at a 7 times multiplier.
