AMD "Thuban" Core (Phenom II X6) XS Overclocking Charts

[Particle]

Hello-

It is my intention to start an overclocking chart for the new AMD Thuban core CPUs for members of XS.

Please read this information carefully before submitting your entry!

If you want on the chart, please post the following information here and then PM me the post number.

Here is an example. Please copy and paste this form, as my program needs it formatted in such a way to import your data. ALSO, please specify when posting if you are updating a previous entry (and specify which one) or adding a new one. It is conceivable that people may have more than one of these, so I don't want to assume your intentions.

• CPU Model: AMD Phenom II X6 1090T BE
• CPU Stepping: CCBBE CB 1011BPMW
• CPU Frequency: 4000 MHz
• CPU vCore: 1.475V
• CPU Multiplier: 14x
• CPU Turbo: Disabled
• CPU NB Speed: 2200 MHz
• HT Ref Speed: 200 MHz
• RAM Speed: DDR3-1333
• RAM Timings: 7-7-7-24-2T
• RAM Configuration: 4 GB (2 x 2 GB)
• RAM vDIMM: 1.65V
• Motherboard: ASUS M4A79T Deluxe
• Chipset/Socket: AM3, 790FX + SB750
• Cooling: Air (Freezer 7 Pro)
• Temps: 40C Idle / 65C Load
• Operating System: Windows 7
• 32/64-Bit: 64
• Stable/Suicide/Untested: Untested

Stable = Tested stable for 8+ hours as defined below.
Untested = Has not crashed or shown signs of instability but no formal testing has been done. May or may not be fully stable.
Unstable = Has shown signs of instability. It has BSOD'd, crashed, restarted, mis-calculated results, errored during WCG, is acting funny, etc.

Stable, for the purposes of this chart, is defined as a minimum of 8 hours of OCCT, Intel Burn Test, LinX, y-cruncher in stress test mode*, or Prime95. Prime set to blend or OCCT set to medium data set are currently the preference since it tests both the cores and memory systems simultaneously. You must have a screen shot of this in order to be added to the chart as stable as of May 1, 2010.

* Launch the program, press 2, enter, 0, enter, x GB (x being nearly how much RAM your system has free according to task manager), and press enter. The program will periodically indicate how much time has been consumed for the testing.

Load voltage is best reported as your actual voltage, not your VID (what is set in BIOS) if available. Many motherboards droop or overvolt versus the specified VID when under a load, and that can be a significant change. A multimeter is best, but integrated sensors are better than nothing. Report just your highest vCore be it under load, BIOS, or idle instead of your average.

Temperatures are best reported as your CPU temperature instead of core temp. Core temps aren't reading properly with these new chips yet. Programs don't seem calibrated for their values quite yet and will report temps -10 to -20C versus actual core temp.


The quick version for what to expect (stable) from an average Thuban CPU:
On Air: 3900-4100 MHz is typical. 4000 MHz even is very common.
On Water: 4000-4250 MHz is typical. 4100 is probably reasonable, but ymmv.
Cold (SS Phase, Chilled, etc): 4300-4500 MHz. We don't have a lot of samples of CPUs having been stress tested under cold, so this is as much guess as observation.



The charts, sorted by CPU frequency first, then vCore, then NB frequency. After that they're sorted by Poster and finally post number.

Thanks to the new forum software upgrade, full-sized images are no longer possible within the thread itself. Grumble. Click on "View Full-Sized" above any image you want to see.

Andy, it looks like you left some of my example values in there. Can you please double-check your data for which fields are correct? Just blank out the ones you don't know.

Initial charts are up. We need more submissions!

[FlanK3r]

particle: dont worry , wait some days...Thubans are "fresh"

[Titan7171]

Hey Particle great work on the chart........Im wondering could you add names to it? Itd kinda be nice to see someones result and know who it is and maybe ask about a particular setup or settings!.......

EDIT NM I see the names at the end there

[JohnMike]

I have a X6 1055T and Asus Crosshair IV here but i'm noob in AMD world.

I would like some tips from AMD lovers about NB ferquency: it's importance?!... it's limition and it's connection with HT ou CPU Bus?!

What's the first and main steps for overcloking a 1055T?!...

Best Regards

[richierich]

Higher NB speeds helps to speed up communication between the CPU and Integrated Memory Controller (I believe).

What I do for overclocking is to see how high I can raise the HTT while still trying to use the stock vcore.
Then once you hit a wall, bump up vcore a little and see how high you can get and repeat. Once you find a good speed, go ahead and try raising NB multiplier. Bump up CPU-NB voltage a little. Remember, the more CPU-NB you use, the more vcore you'll need as well.
You're going to also have to disable turbo mode (and Cool 'N Quiet). I've hit 3.6GHz / 2.2GHz NB while still on default vcore (Prime95 Blend Stable).
The trickiest part of overclocking AMD processors is trying to find your highest CPU clocks + NB clocks + Tight memory timings. There are different voltages to adjust, but I'm not familiar with Asus motherboards.

And with locked multipliers it is difficult when playing with RAM speeds as well.
With default speeds try overclocking your memory and see how high you can run, but with tigther timings (1333MHz CL 6 is good, CL5 even better. 1600MHz CL 7 is good, 6 is better and so forth).
AMD love high NB with tight timings.

Good luck!

[SquattingDog]

Just saw this thread, already shipped my first 6-core system, but didn't take the stepping. It's most likely the same as the one which is ready in a box to replace my Q6600 which I just sold...

* CPU Multiplier: 16.5x (Turbo multi, actualy multi 14x)
* CPU Turbo: Enabled (790XT-USB3 exhibited in BIOS and CPU-z scaling to 4GHz, however it should be 3.9GHz) - found 3.4 + turbo w/ 2430 NB > 3.7 no turbo w/ 3650 NB
* CPU NB Speed: 2430 MHz
* HT Link Speed: 2430 MHz
* RAM Speed: DDR3-1610
* RAM Timings: 9-9-9-24-2T
* RAM Configuration: 2 x 2GB

* Operating System: Windows 7
* 32/64-Bit: 64
* Stable/Suicide/Untested: Stable (12+ hrs Prime95 on all cores + 3DMark06 looping all tests bar CPU, OCCT LinPack Stable)

With default speeds try overclocking your memory and see how high you can run, but with tigther timings (1333MHz CL 6 is good, CL5 even better. 1600MHz CL 7 is good, 6 is better and so forth).

Good luck!

Some great advice from Richierich there. Make sure you purchase memory which is tested to work well with your board at the rated specs/can handle higher voltage/has been tested and confirmed working at tight timings.

Richierich, what is the stepping of your CPU? It would be good to have your OC in these tables too

[richierich]

1010BPMW. I can't decide which config I'd like to post up, either my sweet spot 3.95GHz one, or my highest, prime95 stable clock. Either way, I should have one posted tomorrow.

[Polizei]

Can you define "a few hours" when it comes to stability testing? If it's 2 or 3 (for prime95 (also what settings do you want, blend?)), I could get you some prelim numbers later tonight for my 1055T.

[Particle]

I'm not a stability nazi by any means. Use whatever method you'd normally use for determining stability. The more time the better though. The more accurate the submitted numbers are the more the chart will help us determine overclocking trends.

I'd recommend as much stress mode on y-cruncher as you can stand with a minimum of 2-3 hours.

[soya_crack]

Hi guys,

I am new to AMD Overclocking as I am coming from my Q6600. I just got a T1090 and wanted some easy oc. So I tried 19*200 @1,55Vcore crunching, but it wasn't even stable for 5 mins. Temps are at 42 Degrees. Now I am asking my self if there is another Voltage which is important, when I do some easy "raise multi" Ocing. I left my NB-Vcore at 1,15V but do I have to raise that one even though I didn't oc the NB frequency? The reason why I am a little bit confused is the fact that I saw some badass stable screens from other guys with even less CPU voltage.

And just to make it clear, I am looking for 24/7 crunching stability.

Thanks
Soya

You shouldn't need that much voltage. As you get higher, it's actually possible for it to start hurting you faster than it helps.

I suspect your problem is Turbo and Cool'n'Quiet being enabled. Your Turbo multiplier is going to be +2x, and if it is still enabling at times your CPU will be trying to run as high as 4200 MHz and likely at a reduced voltage of 1.475V. You might try editing your P-tables using K10Stat to make sure this isn't happening.

I actually disabled Turbo and C&Q. And as I crunch on all 6 cores Turbo shouldn't actually kick in.

[charged3800z24]

Partical, I really think we need a SS as a must to be added. I can make up numbers right now and don't even own a chip.

where is the Turbo option located on the 890GPA-UD3H? I have the F5 bios.

Look for an option called "Core Performance"
