Ok I dont think turbo mode is working like its meant to...

Single threads should run at 3.46 GHz...

So i disabled Turbo and manually overclocked to 3.46 and I get a much better score in 2001...

I believe the cpu clocks up to 2.93 which is the turbo for all cores but doesn't swith to the faster turbos for 2 or single threads...

Anyone know what to do here?

When you overclock manually and turn turbo-boost off, all four cores are at a constant 3.46 ghz overclock whilst in turb-boost only 1 core is being boosted to 3.46.

Mau1wurf1977 · 1st February 2010, 8:52 PM

Yes that is my understanding. And surely 2001 is single threaded?

I think it's because of the cores are probably switching between default and 3.46 ghz and not remaining at 3.46 ghz throughout the test while turb-boost is on.

Doing another run at 2.93 to see if the score matches up with the stock score...

You might be right. Because I believe it just uses 1 speed bin up. And not the extra ones. Which is a shame, because thats one of the features of this CPU...

Oh well more researching...

The other cores can boost a little bit as well but with one core it boost the most, I think it was either 2 cores can boost a little, 4 cores can boost a little and 1 core can boost the most.

not bothered to find exact figures on how much they boost.

think you can set the c1 states to choose how they boost as well I think, iirc c2 state, c something c6 states not sure about this, maybe someone else can clear this up. I just left mine on auto.

Mau1wurf1977 · 1st February 2010, 9:18 PM

Might be a bios/mobo limitation...

I tried prime95 1 thread and realtemp shows 2.93 GHz...

Running 2001 now with cpu affinity set to 1 core, but it allready looks like the normal speed...

Why don't new things just work :-( There is always some bug you need to hunt down.

mAJORD · 1st February 2010, 9:25 PM

all of the problems associated with turbo and core speeds in general I've attributed to one or a combination of power saving features..

Leaving them all on Auto tends to work, but try disabling one of them and you'll get these sort of problems.

I had the same issue the other night on P55M-UD2 when trying to do runs with speedstep off, I think I had to end up turning it back on to get turbo mode to work to full bin. This problem only seemed to appear on the latest bios.

I know you had it on earlier in thread, but just incase you turned it off!..

Mau1wurf1977 · 1st February 2010, 9:37 PM

Going to load bios defaults and see what happens...

I have the latest bios. There is a beta bios but only for ocing the video card on the dual cores...

No luck... Might be a bios issue.

Will send Gigabyte a message and see what they say...

Turbo mode works fine, but only up by 1 bin...

In the BIOS there is an overview page with all the turbo modes. But it only shows 22x multi for turbo and 21x multi for default...

There is a option for C States which is auto. I have tried Enabled but no difference...

So yea I guess its a bios issue...

mAJORD · 1st February 2010, 10:30 PM

22x sounds right in the overview because it only shows the multi for 4 core Turbo (1 bin) iirc

Mau1wurf1977 · 1st February 2010, 11:30 PM

Okidoki installed the OS again because of my memory card reader that was plugged in the HDD was drive J :-(

Did a 06 run with everything on stock.

I got 15711 3DMarks with my Radeon 5750...

The cpu tests still lag like crazy though...

You know you can change drive letter associations in Computer Management, right?

~~Same issue with Turbo mode under Windows 7. I wrote a message tp Gigabyte last night. Lets hope something comes out of this :-)~~

FAIL on my behalf... Turbo is working just fine...

When I did my tests with Turbo disabled I wasn't aware that if you set the multi to 22 it will enable Turbo again. So the multi has to be 21 in order to disable Turbo mode...

Also CPU z and Core Temp are useless in showing the true speeds and Turbo multis.

Rather rely on a benchmark to see what is going on. I uses Super PI and ran the 1M test. Super PI is single threades AFAIK...

Turbo off at 2.8 GHz I got 15.04s, AT 2.93 I got 14.13s and at 3.33 I got 12.49s.

Then I loaded bios defaults and I got 12.34s.

So all is good...

EDIT: More findings!

While Turbo mode seems to work well with Super Pi. It doesn't work well with other applications.

For example with 3D Mark 2001 I get 45k without Turbo and 47k with Turbo. So there is a small benefit, but nothing major.

Now the GB Bios allows you to disable cores. So I configures my machines as a single core, no HT. This results in the CPU running at 3.4 GHz all the time. Ran 3d Mark 2001 and I got 56K. Much better...

This is under XP.

Under W7 I get 42k stock and 45.5k with Turbo and 46K with single core at 3.4 GHz. It seems that Turbo works much better und Windows 7. 2001 still runs much faster under XP though...

Very interesting findings...

agreed! if you're rig isn't configured properly and isnt stable and you want to post about it, do it where its appropriate, not here.
