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

[alex_123_fra]

Slightly disappointing with win 8.1 so far chaps. My 5 Ghz run only netted 789 points. In addition, it doesn't like overclocks of 5.1 and 5.2 which I knew we're stable with 1.52 and 1.53v in win 7 ultimate.

So far, a pig to work with. I suspect my installation is now corrupted so will try a clean install before I write it off.

I was tempted to try out a linux distro but I doubt the benchmarking apps are out on them. Still this win 8 only has 3 months and if im still not impressed I may just switch over and see how it performs.

The AMD CPUs will run better in Linux than Windows for a couple of reasons - the OS is fundamentally better at multiprocessing, and the system and all the binaries are normally compiled with very modern optimisations. You can also find CPU-heavy programs compiled with architecture-specific options, for instance taking into consideration the cache size, but this tends to be rarer (unless you do it yourself) -- this can lead to up to 100% gains in performance in some tasks.

Here is one example. The same computer, same OS. All that's changed is the option used to compile the benchmark, to optimise for a different AMD architecture:

(bdver2 = Piledriver)

With Steam supporting Linux (so lots of games now available) and Win 8 being quite an unfamiliar change/feel it is probably a time where some users will dabble. Having built a new system recently it was a tiresome routine of installing and faffing around, something to consider when comparing license fees over time.

I installed ubuntu on the nephews laptop as it was running dog slow on Win8, he seems to like it a lot albeit with a steeper learning curve to get stuff to work.

hey guys back home at last, thread is looking great you guys have been busy loving all the build pics guys

th0nt what number do you enter for folding @ home team number for overclockers?

gonna give it a shot tonight been working in your native land with the race cars

also what settings should i use?

 

[ALXAndy]

I got back a couple of hours ago too. I missed the whirry hum my desktop makes

Off to bed soon as I'm kernackered but will be tweaking tomorrow

same here but couldn't resist a little dabble first lol gonna leave folding on over night


i will finish first page tomorrow with rest of our rigs! will get as much info as i can from your sigs guys so make sure there up to date please

Wb Rich!

F@H team no is 10 I think.

Must admit, I dropped the multi to 20, upped the FSB by 10 (4.6Ghz) so not much overall core speed lower and the BIOS tweaks seem to be coping fine with the 8 cores crunching at 90% usage (medium).

Browsing, streaming whilst this is going on should generate a more realistic benchmark than other tests. It seems to weed out the faults better, and if I can leave it overnight or a couple of days and it's still running I am more than happy.

Socket temp is 48c and package is 40c, this is with the fans on normal i.e. not cranked up.

cheers dude just set it to run at max or full and im at 43 socket 37 core/package remember im on water so temps are gonna be good even at full and my wind tunnel case

been reading back through and you been making good progress so far! how you liking amd?

im still stable @ 4.8 managed to up fsb and cpu/nb to 2640 mhz and multi to 22 and fsb 220 completely stable well i think lol

this folding should tell me if i am or not

i found also upping the vdda voltage stops the core voltage from jumping around and helped me get completely stable worth a look , mines a 2.69v im still @ 1.44v vcore

think this is my everyday clock 4.9 ghz gave hardly any better results so why push cpu i say?

I am liking the build, I rarely regret choosing after informed decisions to be fair this is why speaking to people and threads like this are a must before buying hardware.

My last rig was intel with C2D E8500, I bought the same back then - top board (heatpipe tech), good components and it showed lasting me around six years.

This time just because it was AMD did not throw me, in fact the scorning from the intel fanboys actually made me root for the underdog more. When I see you guys clocking well and plenty of depth in the board to tinker with I liked that and wanted to join the ship.

Out of interest it would have made it interesting should your mate wanted to part with them bits and what he wanted could have been a completely different outcome. Really pleased so far with my rig, my only concern is I took out one of the GPU's on a lock up which resolved the ensuing booting issue too - I hope it's not damaged.

The folding will definitely highlight any cracks, if it's fine then you could always set to full and really see if there are any issues!

Interesting to hear about your vdda and HT settings, I may go there if I cannot push this up a notch further.

I found the 8 pack thread in his section where he was making an overclock guide. Would be interested in how this goes, sooner rather than later otherwise we will be on SR if he leaves it any longer!

Only half the bits have arrived so no watercooling this weekend. Will tidy the internals a bit and move the drives from where the rad is going up into the 5.25 bays. This case is too small really but I have got used to it.

So having a vinyl weekend but will keep an eye on progress.

Spoiler

 

[gpuerrilla]

Yesh! Nothing beats a good long piece of 7" over the weekend.

No of uses for your 8 core rig (thread to be updated by farmerboy providing a current recommendations list): I will start

1. Rip your vinyl collection to digital format

 

[Hagar]

[*]Rip your vinyl collection to digital format

Must admit I keep starting to then get distracted. I do have quite a few on Hard disk but I prefer listening to vinyl recordings through the deck and phono box. I use spotify for digital listening generally.

 

[farmerboy-86]

th0nt i am at full with the temps i posted above as well seeeeeeet! lol

just jumped couple of degrees but no panic for my uber watercooled death machine, so far i will add! lmao

time will tell?

yeah vdda really help get this puppy stable also read a lot of places thats how they stopped vcore bouncing around, i can confirm it works and with it brings stability

gonna put my gpu water block on tomorrow then im fully under water gonna hit benching on head for a while (will still post here, mean im not gonna spend night after night playing with settings) i have so many games i have brought and not played, happy with 4.8ghz for now

Seriously mate I need some pics of the watercooling - I am tempted to get into this sordid world would love to get the GPU(s) cooled but the budget 7770's aren't worth it.

If it can crunch at full overnight then you got it stable in my eyes!

Welcome back chaps (Andy and farmerboy). Farmerboy I can't fit both rigs in my sig so the AMD rig is now as follows:

8320 @ 4.8 Ghz 24/7 but tested to 5.2 GHz IBT stable
Crosshair V Formula Z
8 Gb G skill Ripjaws Z 2133 MHz 9-10-10-29, also used 8 GB Gskill Trident X 2400 MHz 10-12-11-30
7950 HIS ICEq boost

Best cinebench R15 score=829 at 5.15 GHz - out of interest, just looked and that is the top 8320 cinebench score on hwbot in world rankings and behind 3 8350s. I do think these chips can give more:

http://hwbot.org/benchmark/cinebench_r15/rankings?cores=8#start=0#interval=20

 

[gpuerrilla]

I certainly think there's more in them too. It goes down to stability tweaks I reckon, to balance out spikes. I have run this machine overnight with all cores 90% top temperature was 52. That was without the corsair fans on takeoff.

Would love to see what 8 packs guide on this is.

Yep would be great to see 8-pack's guide.

Some more testing on Cinebench R15:

Here is Windows 8 at 5 GHz - best of 10 runs - Score 794:



Here is Windows 8.1 at 5 GHz - best of 10 runs - Score 787



Neither Win 8 or 8.1 mnanage to beat the win 7 ultimate score of 803 at 5 GHz. Moreover I cannot seem to get the CPU to play above 5 GHz on either win 8 or 8.1 even with very aggressive voltage and phasing. Win 7 ultimate plays nicely at 5.15 and 5.2GHz. As a result of all this I haven't put in my Trident X 2666MHz memory to test with Win 8 as I doubt it will get close to the 829 score achieved on win 7 ultimate. May be early days yet in terms of the maturity of the OS so I will stick with it in case some updates come around.

Aside from cinebench score, win 8.1 feels very responsive and slick and I quite like the new start button. Not the same as the old but most common features accessible from there.

 

[ALXAndy]

Makes you wonder if Maxon have even bothered with Win 8.

 

[gpuerrilla]

It certainly has something to it, faster booting/shutdown is welcome, some control in Task Manager is nice you have to try something out properly before deciding so will reflect when I have used ot for a couple of weeks.

Interesting to hear about your score dipping over windows version. Did you use the same chipset drivers etc or were they slightly different?

Someone mentioned their board has a new BIOS since 8.1 maybe this could have an effect.
