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

[ALXAndy]

I'm still jealous of not having an 83xx set up, it's getting worse.

As to Cinebench, it's obviously a rounded benchmark, but it's not the be all and end all of multi-threaded benchmarks. Povray is a good second one, but it doesn't have any fancy results screen like this.

e.g. this one shows the 4770K and 8350 at stock being dead equal:

I'm curious about that now. Passmark also seems to return quite high results for AMD. I'll be back home on Sunday. I think it's going to be benchmark bonanza Sunday (after the footy of course )

Oh and Thont - great name for the computer I still go into device manager and look at the 8 cores quite a bit I have to confess

And yeah I'm with the others. Get some decent fans man. I've got Cougar Vortex and they're ace.

yeh I swapped my H80 fans to Noctua NF-P12s and now run it full speed 24/7 with the same noise as the standard fans on low. Knocked 8 or 9° off temps.

Man I think my Noctua 140mm fans are pretty loud at full speed (although 30% is enough to cool everything unless I'm running prime). Those standard corsairs must be like a jet engine?!

Has anybody tried benchmarking on Win 8.1 vs 7? Would be interesting to see firestrike and cinebench scores.

From what I saw 7 actually posted higher scores in Cinebench. Which is odd.. I might even dual boot with 7 ultimate and compare the two side by side. Now that would be a project to take up some time. I could also compare games and apply the hot fixes to see what happens there.

Latest bench:

Spoiler

Going higher starts to show instability. No BSOD or anything but apps don't like it so this is where more tweaking is in order to go higher. I put 1.49 vcore, so probably showing the 8320 ceiling for stability around 4.8 but there's plenty more tinkering to mess about with.

Looks good Thont mate. I think 4.9/5 Ghz is not unreachable. If the cooling is man enough, it will be fine. Also trying to find if there is chip degradation at 1.5+ volts but can't see any data on this. I am currently not thermally limited in terms of pushing more. Just too big a chicken to go over 1.53v. The latter nets me 5.2Ghz.

 

[gpuerrilla]

I think maybe the NB could need looking at, are you guys injecting a value for that or leaving it at Auto?

I found my GPU connection was loose so maybe that contributed to a lockup/booting issue. Currently put the vcore up to 1.5 till I get it solid then will back off later for heat purposes.

They really are mate! I don't know how anyone could run the h80/h100 at full speed with the standard fans, unless the case was kept in a different room. of a different house

 

[alex_123_fra]

Stage 1 prep. Just had a spare standard AMD backplate drilled out to take the EK CPU block fixing bolts. I don't know why EK omit this plate, well I suppose I do, cost. I would not like to clamp it up without a backplate.
I may be up and running this weekend, but it is more likely to be next

This sounds awesome. Can't wait to see it. Agree re:backplate. Poor show by EK. I used a plastic one from my antek 620 cooler.

arghh.. so frustrating. i cant better 4.9ghz even with the crosshair! think i just need to go Cold, brrrr..

dont really want to spend more cash on water cooling unless i know it'll give me the results i want

What are your bios settings mate? Some screenshots would be great.

 

[mx0range]

got fed up and set it up at a very reserved 4.2ghz without saving any attempt at 5ghz

the last thing i tried was 200 fsb x 25 with ram at 1333mhz, llc set to extreme / ultra and vcore 1.5v

that atleast got me through post but crashed when windows was loading

 

[alex_123_fra]

Don't give up buddy. Try using FSB and multi combined. I have mine on 233 FSB X 21.5 multi. Enable CPU and PCI-e spread spectrum. Keep memory at stock for the moment. I used 1.51V to get it stable.

In digi+, use high or extreme LLC, optimised or extreme phasing and 130% current cap on the CPU.

What NB and CPU/NB manual voltage did you set? If on auto, what has it set for you?

I have been reading a little on this platform and it seems 1.55V is the max people are prepared to use for day to day use, although I'd personally prefer less than 1.5V. For benching up to 1.6/1.7 is useable on watercooling (LN2 obviously more).

 

[mx0range]

i tried a higher fsb and got nothing but a blank screen.. wouldnt post.

in digi+ llc was set to the highest and current was on 120%

cpu/nb 1.2v
nb 1.1xx i think. left on auto

not used to the amount of options you get with this bios!

 

[gpuerrilla]

I dont know how I would find this but if I knew what VIN3 to VIN8 where on the voltages I could see what it maxes at.

Yeah some of them may be meaningless but having too many options without a better explanation other than the notes column on the right telling you nothing.

 

[Orch]

Enable CPU and PCI-e spread spectrum.

I thought these were supposed to be disabled?

 

[mx0range]

I thought these were supposed to be disabled?

me too, iv always disabled it

 

[gpuerrilla]

I thought these were supposed to be disabled?

On my previous build (C2D) it ran with solid stability when you disabled spread spectrum. I kind of agree with your thinking but I will see what others say.

 

[alex_123_fra]

Spread spectrum should generally be disabled when overclocking on multi only. On FSB OCs it nearly always nets me better results though so I would recommend certainly trying with it enabled. CPU more important than PCI-E in this regard but if you are benching, both help.

 

[gpuerrilla]

Taken from the ever so helpful motherboard manual:

CPU Spread Spectrum:
Disabled - Enhances the BCLK overclocking ability
Enabled - for EMI control

PCI Spread Spectrum:
Disabled - Enhances the PCIE overclocking ability
Enabled - for EMI control

cpu/nb AUTO I suggest.

I would try with a slightly increased bus and reduced multi. even if only 210MHz. I use 130% in the LLC for the CPU and 120% for the NB at 5GHz also I push it up to 1.525GHz. My best results were at 280 x 18 for 5GHz.
