Need help pushing 8320 higher.

post #1 of 12
Thread Starter 
Hello guys.
As the title says, I would like to push my FX-8320 higher than the current overclock, which is 4.5 GHz at a 1.4 voltage with Ultra High LLC (I followed the "Bulldozer overclocking guide")
Temps under load with Intel Burn Test on Very High are 61C.
Here's a CPU-Z screenshot under load:


I have a H100i cooling my 8320, with the radiator fans configured as intake (I'm not sure if this is the best way, but I have 2 fan filters blocking some dust.) Aren't those temperatures a bit high for a H100i?
Should I just keep trying to increase the FSB/multiplier/voltage or stop because of the temperatures?
As you can see from the CPU-Z screenshot, I overclocked by increasing the FSB and changing the multiplier. Should I just go with a multiplier overclock?
Thanks guys!

You should be able to get to 4.5Ghz with less voltage.
I assume you just changes FSB, Multi and CPU voltage.
There's a lot of other voltage settings in your bios that will help.

FX 6300 4.5 GHZ @ 1.32v

Wow, that is a really low voltage for 4.5 GHz!
I tried lowering the voltage: the first time I got a freeze with IntelBurnTest, then I upped it a bit and no freeze. The voltage is still lower than before though.



Oh yes, there are a lot of settings on my motherboard's BIOS. Here's what I'm currently using:





What should I try?
Thanks!

Is it really accurate to compare the 8320 chip and the 6300? the 8320 has "2" more cores than the 6300 (I know that 2 more cores really means just 1 more die). Also it depends on the binning of the chip, the power supply (how well it provides power through the railings), and sometimes the ram speed & bus speed that you set to. In all honesty there is no single method for the best/efficient overclocking it simply takes time and time experimenting with your chip.

Plus 1.4 for a 8320 sounds about right for 4.5 Ghz

Turn off all power saving functions, when I ran a 8350, I turned off all power saving functions and was able to get better voltages.

That's why I'm asking what should I try next, not what settings/clocks I should set my CPU at. biggrin.gif

All power saving functions are turned off (EPU, C1E, SVM, Core C6 state, Amp master mode).

That's still a mighty overclock for an 8320. Supposedly the FX series shouldn't go above 62C but intel burn test is a worst case scenario. I'd say stay under 70 for sure.
As far as voltage goes, that is actually less than average in my experience for 4.5 on an 8 core. I'd say set it to 1.5, watch the cpu and vrm temps, and see what you can get out of it. Messing and testing with load line calibration helps a lot too.

I think the voltages look acceptable for 4.5.
In my experience, using ultra LLC can contribute to higher temperatures. Have you measured your vdroop and adjusted LLC accordingly?

On my Gigabyte UD3/8320, the highest LLC setting can make my temps up to 10C higher than when set on medium, but the only thing I've ever needed to set the LLC to high for was to pass Cinebench @5GHz.

Well I was expecting higher temps to be honest. I just tried 1.5V with High LLC and here's CPU-Z under load:



Max temp with IntelBurnTest on Very High was 64C, so not that bad. What do you guys say? Should I try and keep pushing the clock with 1.5V or are the temps too high? That's kinda what's worrying me.

Those temps are fine. Other people would tell you otherwise but look at it this way. On the stock AMD cooler on my 8350 I had, temps had no problems reaching 75c. I ran it like that for a year. So...just don't go over 1.55 on the vcore unless you are into taking risks.

dude like they said in earlier post's you don't need that high of voltages to hit 4.5ghz.

I have a 8350 running at 1.4v at 4.7ghz but every chip is different.

Your overclocking of the FSB doesn't really gain much for FX processor. Try just OCing with your multiplier you should be able to get higher clocks with less voltages.
