stability is a bit of a pipe dream anyway... even at the manufactures defaults there is an expected error rate on every component... software and hardware alike actually... so stability is more or less subject to how stable you want it to be.. .otherwise what would be the point of ECC ram and raid arrays in servers... not to mention gpu's that offer double and quadruple accuracy in compute tasks... is really a question of how stable you need/want it to be... most just want to be stable enough to not impact performance or corrupt windows... and that actually takes a lot more than people think... but in general.. if you can pass IBT AVX on very high and at least an hour of Prime blend you'll be ok... if you really can't stand to lose your OS or data... consider more drastic tests.

btw.. I'm aware that there are those who passed those tests and still had very bad corruption... but understand... I had very bad corruption on a computer that passed 24 hrs of prime 95 blend... turned out to be the hdd lol

i have a 970a-ud3p rev 1, i do have a vrm block but its too short by 15mm,

i done a run at 5ghz but vrms hit 115c

I upgraded my cpu to the fx 8320e (1055t has been sold)
And wondering what overclocks prople have been getting.

Im also inrigued about how proples vids compared to mine gor overclocking. At stock mine says its 1.113v that is pretty low
post #50076 of 68053
its really a crap shoot... but many people have been reaching 4.5ghz lately on decent cooling... and on extreme cooling 5ghz has been getting pretty common... but still it's a lottery... I've seen some peoples chips that wouldn't get past 4.5 on custom loops even.. and others like mine that 5ghz stable was a breeze... 5.42ghz fun run even. I tend to use IBT AVX at very high for my stable/unstable determination... but its not what one would call truly stable... but just good enough for me... check out my 5ghz 24/7 club (link in sig) there is a list of people in there and the voltages they use... most are amd.. some are intel too though so be sure to read which is which.

your overclocking will depend greatly on your case airflow, cpu cooler and motherboard. so predicting an overclock is pretty hard. That said AMD doesn't bin it's chips for max overclock but for power bleed. This is a hard one for some people to get their heads around, but basically there really isn't any particularly better overclocking amd cpu then any other. All the 8 cores are almost equally likely to hit the same clock speeds.

The exception of course are the 9xxx series 8 cores. Those are all very high bleed chips, and because they're strictly binned, there aren't "bad" overclockers in that lineup to drag the average down.

yes, your vid is low, but again... i've found that only to be an iffy predictor for overclocking results in the fx lineup. all it tells me is you have a low bleed chip, which makes sense, because all the fx 8300/8310/8320/8320e chips are low bleed chips. and all low bleed means is you can reach the same clock speeds as a high bleed chip with less power; however you tend to have overheating issues at lower voltages that high bleed chips don't get; as a result, it's all a wash. Typically you'll probably hit the same overclocks as high bleed chips, your vcore will be lower and they'll have a slightly easier time of keeping things cool. but overall it doesn't mean much.

Cheers for your input its enlightened me abit more.
Ive noticed it does run the socket hotter even though the voltage is lower than my 1055t i put that down to 8cores n newer arch.
When i booted it up i set 1.15v as the stock voltage. I thought put it on auto n see what it says n it wasnt even 1.1v

Im running it on my crosshair v formula z with corsair h100i.

After that, if your system pass +12 hours of Prime 95 custom assign 80-90% of your total RAM, it's a good indication of stability...

IBT AVX is just as effective as prime, occt. (well there can be an argument that IBT is more effective than prime, but that is just based on time)

they all do the same thing equally well. its about what you prefer to use, Know how to use it, and have the patience to use it properly.

I swear by avx IBT for the last two years. I can tell you first hand IBT is more than enough to prove stability.

you can reduce the temp on your socket by using LLC controls. Most new comers are rather fond of V boosting their chips.

For the most part Vboost is a bad thing unless you are into subzero exotic overclocking. most chips don't like it all that much, and it is one of the worst offenders for socket temps.

try High LLC and adding Vcore to account for the vdroop (yes vdroop can be good)
