***official amd 83x0 overclocking thread***

Started messing with the volts last night, but it just kept getting hotter and hotter haha. Had to stop it at 60c, although that wasn't package temp. So started messing about again and got the volts to 1.39 on a 4.6ghz. Couldn't get linX to run so just used prime again and after 5 passes it was only about 46c(again not package)

TBH mate don't worry about temps. Firstly your CPU and the motherboard have a limiter which make it very hard to damage the CPU. It will simply shut down, reboot or freeze when the CPU gets too hot, or, the board will throttle it.

I used to have a Phenom 2 940 Deneb which could do 3.9ghz on a Noctua NH-D14. However, if it got to 43c? lol, didn't matter how much cooling I added that was its limit. Keep it under 43c? it was perfectly stable in anything. Funny really, but that Deneb literally had a temperature limit and if you stepped over it the PC would simply shut down.

1.39v is pretty lame for a FX 8 though. I'm running 1.44v through mine at 4.7ghz and can easily get a stable 4.85ghz using 1.46v. The thing is? taking it up to 1.46v meant 61c under stress test. 1.44v @ 4.7ghz means 51c and there was pretty much no yield in performance by adding another 10c which made it pointless. With my CPU putting out 61c the back of my rig got hot (the IO shield) and you could literally feel the heat being pumped out the back.
 
Oh I thought 1.39 was good for that speed? I'm a complete noob at overclocking haha. I assumed the more volts, the hotter it gets. So at such low volts(1.38 being stock I think) I thought I was doing good.

So really, it's keep pushing till it stops working?

Here's a question about overclocking, wrong area but saves a new topic. Memory. I've got some 1600mhz Sammy greens. Now obviously when you overclock, the ram gets faster. What I was doing was downclocking the ram speed, so when I overclocked it was pretty much matching stock speed. Is that fine or is it the same? Keep pushing till it stops?
 
1.385v-1.39v is more or less that any FX8320/8350 can do at 4600-4800. Surprisingly most 8320s can do it with less voltage.

You are safe all way to 1.5v if you have watercooling or H100/H100i with really good fans like Akasa Apache. However if you cannot go post 5000 even with 1.5v forget it. The chip will not go higher up even at 1.55. Put the cpu back to 1.4v and run it at 4800-4900. Those 100-200mhz ain't worth 0.11v more because it is +10% power for ~4% speed.
 
I'm at 4.2 on the stock cooler, stock volts (with some line load balancing etc) with the 8320 / M5A97 EVO R2.0.

It's stable but gets in the mid 60 temps on prime testing.

Is that about right until I get a competent cooler?
 
Yes. Stock HSF isn't good enough, even if it has all those pipes.

If you have space get a refurbished H100 and put 4 Akasa Apache or Enermax Magma fans to it running at full speed. It is a great investment.

Or else get a Noctua or something similar.
 
Sweet, i'll invest in a H100 after christmas I think.

I just thought though, I have an old Thermalright Ultra-120 Extreme that I used on my Q6600, it's a hefty old beast for it's day. I never considered that it might fit because it's so old.

I might take it all apart again just out of curiosity to see if it will go on. I only have the adjustable "cross" type mounting for it though, like this:

hey guys i know i aint been heard off for ages i got abducted i think :p

thread has moved on some what i see.


Been concentrating on gaming as i have a tonne of games to complete, i think the overclocking and benchmarking took over my life at one point

got my rig to 4.9ghz stable @ 1.452v

cpu/nb and ht link both running 2685 MHz with a little voltage bump

multi 22
fsb 223

think thats where she will stay for now temps are cool but time of year helps

idle 27
gaming hits 39/40 socket

What temps are you getting under prime?
Click to expand...

stopped using prime dude as its unreal on cpu never gonna hit that temps in real life situations

its purely a gaming rig if it games im happy

gaming and on aida64 i hit 40 socket 36 core im on full water custom loop with vrm fan mods and socket mod on rear of mobo she stays cool :D

got 798 on cinebench too

Guys I had a question I got my 8320 stable @ 4.0 with 1.32v (m5a97 r2 evo board) I used this guide: http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard

It's all fine and dandy but my CPU is not clocking down when I'm not doing anything.

Cool'n quiet = enabled
C1E = Enabled
SVM = Disabled
Core C6 state = disabled
HPC mode = enabled
apm master mode = auto

Any settings you guys recommend changing?
Click to expand...

Try disabling HPC (high performance computing mode)
 
right as you know i cant oc my 8350 with the mobo and the xigmatek aegir cooler i have, it just wont do anything!
im thinking of buying a new case and mobo, the m5a97 EVO 2.0 and using the same cooler i have which is nice, 2 fans in push pull configuration :D, but by just changing the multiplier in the bios what speed stable 24/7 gaming will i be looking at without changing voltages...il leave it up to you guys, see what you say
thanx
edit.
forgot to mention it now idles at 27-30c
