**LETS SEE YOUR PILEDRIVER OVERCLOCKS - LET ME START WITH 5GHz+!!**

Almost as bad as the 'lets look at performance at low res' benches. I understand why they do it, but I've never felt that it's really relevant to me playing games on my PC.

With CPUs though it doesn't really matter who's backed them IMO. It's not like GPU drivers are invloved because it's all done on AMD GPUs. If anything it just goes to show how badly optimised so many games are for modern CPUs.

Some crazy 4 way Crossfire :p?
I can only stomach 2 cards, and even that's a pain to get it arranged with my sound card, got 2 7950's in there now and I can't wait to go single 8970 when it launches.

8950 looks interesting to me, but i also want to see what Nvidia have to offer this time round.
Hopefully they will look at their pricing structure, i fancy a change but there is no way in hell i'm paying more for the same or less.
 
Well I just purchased an 8350, was going to go for an 8320 as the price is really competitive @ £124.99 for the same chip. However for the extra £25, I thought it worthwhile spending the extra on the binned version.
I will be using an Antec 620 on it paired to a Sabertooth 990FX (v1) board, so not expecting huge overclocks, but I have plans next month to switch to a H100i so hoping for better results then.

Thats the same Motherboard i'm using, i would be interested to see how it does :)

Well I am very happy, I appear to have got a decent roll of the dice on the silicon lottery :)

4.8 24/7 stable @ 1.45 volts, running a 24 multiplier so far.

Turbo core disabled, all C states still enabled, running ultra high LLC to combat vdroop and 130% current capability, optimised phase control, core temps circa 54-56, seems to be the best balance I can find so far between performance, reliability, efficiency and temps, I imagine there are a number of ways to get to this speed safely that I have yet to try.

Can hit 5 stable but need to bump voltage to 1.5, and temps begin to rise sharply (62 and rising after 15 minutes of AIDA), so would need something better than my Antec 620 before I was happy running it at this speed.

Chris.

Very nice, 4.8 seems to be the 'Goldilocks' zone for the 8 core Piledriver on decent but not over extravagant cooling.

It seems that 4.8Ghz to 5Ghz is a much bigger hit on volts and temps than 4.6Ghz to 4.8Ghz, having said that anything up to 65c is fine.

Have you tryed running at 120% current capability?

For my own 1090T i can get 4.15Ghz @ 120% current capability; Prime95 stable (50c Cores / 60c Socket / 1.43v + Ultra High LLC / 1.44v Load) if i try and Prime95 it at 4.2Ghz it BSOD with in minutes.

If i turn up current capability to 130% it will Prime95 for hours on end @ 4.2Ghz (Cores 54c / 67c Socket / 1.46v + Ultra High LLC 1.48v Load) anything over 4.2Ghz it the cores pass 56c resulting in overheat shut down.
Again just 50Mhz is a big hit on temps and volts, so i just run it 4.15Ghz / 2800Mhz CPU-NB / 120% as the perfect balance.

Believe it or not on this Cooler Master Hyper 412S which is a much better cooler than the price suggests, its one of those little known brilliant £30 coolers that gives a DH-14 a run for its abilities. I haven't even bothered to put a second fan on it yet :D

What settings on fsb etc Humbug? My 960t unlocked unfortunately takes a few more volts to reach 4.1..But then again unlocking them does incur a lot more tdp than standard thurbans. I am 242 fsb , 16.5 multi 2900 & odd cpu-nb

Try using less FSB and more multi....

Yep, now running 204 FSB, 23.5 Multi and 120% current capability, 1.376v under load with LLC (ultra high still) :D

Using BIOS to set things after messing around with AI SUITE to test, on 1604 BIOS it seems you need to force HT to 2600 otherwise it defaults to 2200 for some reason?

1604 is the Piledriver BIOS, the first one at that.

As far as i know its normal, i think it does it when you turn the memory speed up, which happens anyway when you turn the FSB up.

Piledriver behaves differently to Phenom and Bulldozer.

Perhaps an experienced Piledriver owner can give better info on this.

Yes I would be interested to know as at default it runs 2200 NB and 2600 HT, when overclocking by Multi only this remains the same, but as soon as I attempt FSB overclocking, the HT seems to drop to 2200. I manually forced it back up (2654 with FSB @ 204), seems perfectly stable but don't want to damage anything.
