fx8350 OC and cooling

I managed to get 4.3ghz stable at 1.35v. I tried 1.4 but temperatures were around 67°C so lowered it to 1.35 and temperatures don't go above 50°C.
so now I really need a better cooler if I want to go any further with my OC

As long as temps stay in 70's, 67 is nothing. But another cooler would be a great idea.
 
ok thanks. I did loads of research and most people seemed to be saying that 62 should be my max temp for a 24/7 OC.
I've just cleared my cmos and I'm going to start from scratch.

now, about the weird on-off-on cycle every time I start or restart. does anybody know what to do about it?

thanks for the help
 
Hello just for information I contacted AMD directly about the FX8350 and voltages.

They stated the below

Normal core voltage is 0.8250v-1.425v
Maximum core temperature is 70°c

I currently have mine at 4.7Ghz@ 1.4725v this is under water though
 
Ok thanks for the info. I don't know why my voltages are so low then. Is there a way to test my psu?
Everything still works fine though
 
Not sure I know OCCT has a PSU tester, You can also check your voltages with HWinfo & HWmonitor though they are not 100% correct they will give you a rough idea if they are dropping e.g say your 12v is only sending 11.2 etc the same on the 5v & 3v.

I know many people can leave this chip alone in the bios but disable the AMD overdrive or cpu overdrive I think it may be called and hit around 4.4 leaving the voltages on auto they normally hit around 1.3ish under load and 100% stable this does vary chip to chip remember its a silicone lottery

What cooler are you using is it mounted correctly?
What was the thermal compound.
If its a stock cooler I would not mess with any OC or voltages

Sorry if you have answered any of these questions earlier;)
 
Also remember the lower the voltage the less heat generated, Having a low voltage is great as long as everything is stable.

But 4.3Ghz @ 1.3v - 1.4v hitting 67° is high but this will depend on your cooler

I am currently at 4.7Ghz @ 1.47v and under 100% load my CPU will only hit 54°.c This is also with a R9 290 in the same loop that likes to try and hit 95°c but I am water cooled
 
I use hwmonitor as well but the readings are a bit low on every single rail.
I've got all the overdrive features disable as well.
My system is perfectly stable at the minute so I'm not worried. And temperatures only go this high in prime 95. They're lower otherwise. I'll run a few passes in aida64 and see how it changes.
My cpu is not great. It's a xigmatek loki.
I was planning and getting everything under water but I'm skint so I might go for a noctua instead.

Also I can get 4.5~6 on stock voltages stable but I'm waiting for a better cooler
 
Yep they will droop especially using prime95 as everything is fully loaded.

All that matters is stability, a good overclock and good temperatures the lower the voltage the better.

Hope this helped
 
Right so first, I can't run a stress test on aida64. As soon as I start the test, it says "failed". It doesn't even start the test.
Now I'm running prime95 as we speak and here are the readings for my psu (using hwmonitor):
Vcore: 1.320
Ddr: 1.464
+3.3v: 2.004
+5v: 3.387
+12v: 8.064
VIN5: 1.872
VBAT: 1.572

now I'm no expert but these all seem quite low to me.
Last time I checked all the readings were fine in the bios.
All seems to work fine and temperatures were around 57° after 20min of testing.

My psu is a corsair cs650m and it's a month old
 
My father in law is an electrician so I'll ask him when he's back. He's away at the minute fixing power lines because of the weather.
But as I said, readings are fine in the bios. I'll check anyway.
Cheers
