Hi after 9 hours of blend test in prime 95 I have 1 error but max temp is 74 is this OK ?
post #12 of 96
if 74 was the max temp of one of the cores, yes its is ok.
just add one tick more to vcore and you are set.

Yes the v core was 1.220
Add how much ?
post #14 of 96
just one or two notches.. hit + just one time and see if it is enough.

I had fatal error rounding was.5 expecting

Rounding error is instability, it's nothing different than a BSOD. Generally bsod's occur when you are further away and rounding errors when you are closer to the mark but it's still a sign of instability and I've had terribly unstable overclocks have rounding errors and slightly off overclocks BSOD instantly. And now you know why 24 hours of prime95 is important.

It sounds like you just want to hear someone say '12 hours is fine' or '1 error is okay' but it's not. 24 hours, prime95, custom blend with max mem used, priority 10, sum input and rounding checking. You are likely close, just need a bit more voltage. There's lots of bad ivies, 4.4ghz@1.22 is not really that bad though. I've seen way worse.

Are you manually setting voltage or using offset? Since you are right around the right voltage why dont you use offset voltage? Or do you plan to do 4.5ghz or higher?

I put 1.221 try on it or raise it to 1.222?

I manually setting voltage I don't know how to use offset I just want 4.4 GHz if you know tell me how to use offset please
post #19 of 96
I would bump it to 1.225 but it's up to you.

Offset allows your cpu to downclock/downvolt under low load, it's preferable for 24/7 overclocks so that way you aren't running your max voltage and frequency 100% of the time. I mean in a given day you rarely hit max load so with it downclocking/volting on low load, it really extends the life of it and does less damage to it. Think of a car, it'd live much longer idling in the garage most of the day and then speeding around the track a few times then just.... speeding around the track 24/7.

I have no idea what motherboard you have because you dont fill out your sig rig, you dont post your specs, but you can google very simply how to do it on whatever motherboard you have. every chip has a different voltage automatically at every frequency, so you have to figure out what your chip does at X frequency, and then use an offset of +/- what your vcore is on auto, to set it at the desired voltage. it's all out there, google manual vs offset, how to do offset, offset on your motherboard model, etc.

So now you know you need ~1.25v for 24/7 overclock, so play around with offset until your vcore is around there, test prime95. if it fails, more voltage, if it passes, either call it a day or try to lower it. We can't tell you what offset to use because every chip at every frequency is different.

People use manual voltage to figure out their max overclock because manual is usually a bit more stable for less voltage, then when they figure out their max frequency that is 24 hour prime95 stable, they switch to offset voltage, and test for 24 hours again under a similar voltage on offset, and then reduce it and test until it's the lowest that it can be 24 hour prime95 stable at. So I wouldnt worry about trying to finetune manual voltage on 4.4 because offset is the way to go anyways for 24/7 overclocks. It's slightly less stable, generally, than manual, so you might need to set vcore using offset around 1.25, 1.275v, i mean just play around an see.

why only 4.4 ghz? You have a high end cooler, even if you dont delid you should be able to do 4.5ghz easily on a bad chip with the right voltage. Maybe something like 4.5@1.35 and work down from there, maybe even 4.6@1.35, i mean ive seen worse than your chip.
