You would need to compile it. You don't need gentoo to do that though, you could just download the source and compile it on Ubuntu or something. There will be a make.conf file somewhere that will affect every compile with gcc and g++. You would need to find it and add these CFLAGS:

http://en.gentoo-wiki.com/wiki/Safe_Cflags/AMD#FX-8xxx.2F6xxx.2F4xxx_.28Bulldozer.29

You need GCC 4.6 or greater though. bdver2 doesn't come until gcc 4.7, so if you have that version, you can change all the bdver1 to bdver2. You can check by going to terminal and typing
Code:
gcc --version

I compiled blender with -O3 instead of -O2. It takes a little longer to compile but the end code is faster.

I do love my FX 8350 in Gentoo though. I love it when people are like, "get ready to compile KDE, it's going to take a long time!" and it takes me like 30 minutes to upgrade from kde 4.9.2 to 4.9.3.

I might try open64 a little later, it looks like it might do some good: http://www.phoronix.com/scan.php?page=article&item=linux_compiler_deathmatch&num=2

I'm talking proper stable as well, how many in the OP really are?

I've been playing PS 2 for 4-5 hours a day for several days now without shutting off my computer, Although I really should take a few hours to look at my OC again now that I have something to work off of. Maybe get a 201 FSB. tongue.gif

That's true. It's possible that not all the listed entries in the OP are 100% Stable.

There is no doubt that the Silicon Lottery plays a part in VCore. Is it responsible for a 0.09v difference? Highly doubtful.

@ Wolvers - have you tried any of the new BIOS's to see if that helps? I see there is another new one today too, 1201 smile.gif

Very possible. All the OCs in question are within reason of one another, and the board's BIOS and quality makes a differnce too.

FX-8350 4.6GHZ @ 1.5v Regular 23 200 GA-970A-UD3 / 1.1 / F7 - (No VRM Heat Sink, Poor GB Paste)
FX-8320 4.6GHZ @ 1.47v 23 200 MSI 990FXA-GD65/Rev2/V19.9 - (Fancy MSI Heat Sinks. But they generally don't seat well)
VS
FX-8350 4.6GHZ 1.356vSabertooth 990FX/Rev1/1604Bios
FX-8350 4.6GHZ 1.418vSabertooth 990FX / R2.0 / 1006
This is not an ASUS vs Others comparison. But the Sabertooth have been shown to be consistenly built well.
Not sure if these were Brute Force Overclocks. But it would be interesting to know if it is a chipset overheat issue causing the need for this type of VCore. Or if some of these chips are actually just poor overclockers.
The GA-970A-UD3 DOES have vrm heat sinks, in fact the same exact ones as the GA-990FXA-UD3. Same exact 8+2 phases too. Oh and I put 1.5v since that's what it needs in the bios. It only needed 1.44v in windows to be 100% stable. It goes to 1.44v on load due to vdroop.

And also, after putting up my pll voltage, I only need 1.4v (probably less, have not tested) for that 4.6ghz. I'm at 4.8ghz at 1.47v in windows now.

Yay, works for another person! I think we can add upping the PLL/VDDA as a general overclocking step at this point, it's worked without flaw for everyone but those poor ASRock boards that only have 2 settings.

My mistake. I looked up the GA-970A-DS3 Rev 1.1. So your board is a Rev 1.0 without LLC? It was the listing of Rev 1.1 that threw me off cheers.gif

Also, 4.6Ghz @ 1.4 is very nice.

It's neither a comparison of Motherboard Quality, or an Overclockers capebility. The point of listing the two different CPU models on different boards with a similar overclock at nearly the same voltage was to ask the question: "Is there another factor on these chipsets that is causing the increased voltage?"

** also in the example. It's the 8320 that is using less power than the 8350

...........

You test for one factor at a time. You use the same CPU, the same MB, the same MB Rev, and the only thing you change is the cooling (thermal pad vs TIM).

If you are going to throw in more variables (different CPUs, MBs, revisions) then all your calculations are completely worthless.

I hope others will chime in and corroborate or offer a different experience.
My 2 cents thumb.gif

Red, since you've actually tested a number of different ram speed vs. timing combinations, where did you find the 'sweet spot'? Which ram config yielded what you consider to be the optimal balance? Optimal throughput?

Thanks in advance. My 8350 is on its way finally. Motherboard and ram are my next considerations. Just can't decide which motherboard to get. It'll probably not be Asus, since my bios-flashed graphics card won't post on the only Asus board I've tried so far (M5A99FX Pro 2.0). Too bad, because it seems like a very nice motherboard. Northbridge chip actually seems properly cooled on it. Oh hell, maybe I'll suck it up and run the 7950 with the factory bios and just overclock it with software. I just hate doing that with a video card with a dual-bios, but the properly cooled northbridge is important to me.

We are really caught up in synthetics and memory but there has to be somewhere where PD has a bottleneck for games that we can tweak on.

EDIT: I found something pretty awesome: http://www.softpedia.com/progDownload/Intel-Compiler-Patcher-Download-154486.html

EDIT 2: it ended up a little bit faster than without the patch, but within margin of error.

Also does anyone have a link to a clock to clock comparison of a 8350 vs 3770k for something like Handbrake? Would love to check them out.

QuickSync uses the on-chip GPU, so.... no. APUs will, when OpenCL becomes the norm, but Handbreak refuses to use it because it isn't fully cross-platform among other things.

However, their 8 cores and instruction sets love encoding.

Then again, if you're going to go that route, grab a 7970 or 580 and find a OpenCL/CUDA based encoder, such as AMD's transcoder.

Also, completely arbitrary number since you can't encode with the same video I have, but I can encode 6020x1080 video of BlackMesa at about 20fps with stock Handbreak settings with the OC you see in the OP.

The time.. If only we had 48 hour days untill things mellow at work i dont have it, however i my just do a vm with virtual box, im eager to see what these chips have for that, my thuban was amazing! +2 cores o yeah!

Whats great is i actual have a use, now to figure out how to convet a vhd from using virtual pc to virtual box,
After i get that far ill go back to playing with linux, its been a couple years but i loved kde suse

Isnt it nice to see people enthused about these chips smile.gif

I need some help with my oc im solid at 4.4 but if i do 4.5 its not completely stable, i have adjusted to any varience of voltage most i went was 1.472 and still not good

My fsb is 215 , im just not getting it

I noticed the same thing when i had the thuban in and didnt mind cause i was upgrading, im trying to figure out if its my bios, board or psu. I also didnt try a high oc after switching board and i had added a second 460, anyone with ideas or suggestions?

I thought MSI boards were in the group of not liking the FSB to be played with on vishera...

crank down the FSB to 200 and use a multi overclock and see if you can get better OC with better volts... 4.5 should be possible with ~1.3625v or so (that is what i have setup right now) depending on how well binned your chip was

When it worked, I used to use AMD's Transcoder (the Media Codec pack that built the feature into CCC). It was a x.264 encoder, like Handbreak, but it used the GPU too.

For the same file size and quality, Handbrake would use 100% of my 970BE at 4.3.

AMD's Transcoder would use 50% of my CPU, and 20% of my 6970, and get the job done in half the time.

Less heat, less time, OpenCL is incredible. However, I have not been able to use the transcoder in months, because AMD broke it, or just doesn't make it anymore, whatever the case may be. While the "AMD drivers suck" thing isn't true, man I hate that they nuked one of the single best "OEM" programs that I have ever seen.

Not enough people are brave or crazy enough to push an 8-core AMD chip on an MSI board, both from the semi-true reputation, and because they just don't measure up to Gigabyte and ASUS most of the time.

We need more people to use MSI before we can pass judgement on what MSI boards like.

Don't want to dig up an old demon, but I have been running Prime95 again, and have found that at stock speeds of 3500MHz and with a nice low 1.25v the processor is perfectly stable, in which it has been priming for over an hour.
When I am at 4400MHz, everything else passes stress testing, but prime hard locks the system within 2 seconds.
I am now thinking that is anyone if failing to run this application must have a unstable overclock. If the Vishera cores can process Prime95 at lower clock speeds then how the hell can the architecture be responsible or a fault for failures at higher clocks. If it can do it at low speeds it can do it at any higher stable speed.
I am changing my mind on this one. If you are failing Prime95 then your overclock is BS.

On a different note, I have been having great success clocking my Ares RAM at lower speeds with tight timings.
Currently running 1600MHz at 7-8-8-18 with T1, way easier to get stable at lower clocks than trying to shoot for the sky for little reward.
