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

[Particle]

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.

Do you think people would really make up numbers around here? If it's going to be a problem then sure, that makes sense.

Your vcore seems really high for only 3.5GHz.

[charged3800z24]

Do you think people would really make up numbers around here? If it's going to be a problem then sure, that makes sense.

I'd hope not, but for on lookers from web searchers wanting to find proof of concept. Then The PICs help validate it. thanks for making the thread though, I hope to join in soon.

[=SOC= Admiral]

Rich the stock was at 1.375v

[richierich]

Rich the stock was at 1.375v

Well that's what MSI puts I guess. Gigabyte says the default vcore for my 1055T is 1.35v. Don't go by what the mobo says, since default vcore for 1090T is 1.28v I believe.

[=SOC= Admiral]

Will not post at anything higher. Need help for what I might tweek.

I have voltage headroom. temps are 40C on folding load.

[richierich]

If it's not posting, then you need to use different combination of cpu-multi + HTT + memory divider.

Hello guys!
After few hours with my 1090T I'm happy to report first clocks:


* CPU Model: AMD Phenom II X6 1090T BE
* CPU Stepping: CCBBE CB 1012APMW
* CPU Frequency: 4240 MHz
* CPU vCore: 1.45V
* CPU Multiplier: 21x
* CPU Turbo: Disabled
* CPU NB Speed: 2410 MHz
* HT Ref Speed: 202 MHz
* RAM Speed: DDR3-1340
* RAM Timings: 7-7-7-19-30 1T
* RAM Configuration: 2 x 2GB
* RAM vDIMM: 1.55V
* Motherboard: ASUS Crosshair IV
* Chipset/Socket: 890FX + SB850, AM3
* Cooling: TT 120 Ultra + 120mm low RPM FAN
* Temps: 34C Idle / 50C Load (Asus PC Probe II)
* Operating System: Windows 7
* 32/64-Bit: 64
* Stable/Suicide/Untested: Stable (OCCTP Linx x64 20minutes)

I've forgot to take screen of OCCTP, but apart from that I was doing Cinebench 2003 x64 full test, Cinebench R10 x64 full test and Cinebench R11.5.
Over 1hour at that setting before I've moved to 4.32GHz

Also for those interested:
3.8GHz - 1.29Vcore stable
3.9GHz - 1.32Vcore stable
4.0GHz - 1.38Vcore stable
4.1GHz - 1.42Vcore stable
all this was tested with very conservative NB at 2.4GHz and MEM at 1333MHz

I'm loving this processor!

EDIT:

PS. Efficiency is low because I had lots of monitoring software open on 2nd screen + 2h of benching without restarting Windows and few crashes along the path while fine tuning voltages.

nice results lightman!

[Lightman]

nice results lightman!

Thanks!

Now I'm dialling in NB clocks. Either 3GHz @1.25V is unstable or my HTT doesn't like to be @2.6GHz. But so far I'm getting feeling it's HTT because mostly crashes on 3D stuff.

At the moment I'm stable with NB2.8GHz @1.2V


Not STABLE, but benchable:

4.42GHz on AIR all 6 cores

Lightman: Glad you got your new gear! Looks like it's running really nice for ya..

You can go a little higher on your IMC volts if you need too, as long as load temps stay around 53c (at least that was the temp stability zone on 965's).

Anything up to 1.3 should be fine for 24/7 clocks, and some folks push all the way up to 1.5.
I ussually just take small steps up in V's until I see deminishing returns...

I have similar approach
Slowly but steadily I will go up, then I will shoot really high to eventually settle for best performance/acceptable power ratio.
So far I'm really happy at 3.8GHz 1.3V with 4.2GHz 1.45V turbo. Sweet setting and very stable!

Later on I will need to enable C'n'Q, but for that I need stock multi which means a bit of HTT clocking. I think it will be even funnier

[zaraza]

on my GPA890UD3H, I cant disable Cool N Quiet. I can set it to disabled, but when i boot into windows my multiplier still drops down to 4x i dont get it.

[thijs]

Loving my 1090T aswell, will add more info and perhaps a pic or 2 later on,

so far i've managed 5050mhz +- on 1.6V , using a singlestage around -30 , NB can go up to 3.6ghz , not sure if ill get that in combo with 5ghz, but im not done testing yet.
Awesome cpu!

//edit

this is with superpi 1M

As long as you think your SS can handle it, 1.65v isn't going to hurt it too much at -30c.

[thijs]

tried, but didnt really get alot higher. 1.65V it goes to round 10 with 5150mhz.

[Mechromancer]

You guys are having too much fun. I can't wait until I can join in. Great overclocks everybody!

Hey!
I can't wait till you join in! It's great fun for sure!
Today's day went so quickly that I didn't even noticed it's already dark outside! (I was benching from 10AM ). Oh, forgot to eat my lunch

[zaraza]

is 1.42 on CPUNB too much?

I think my 1055t needs 1.55v to be stable in prime @4ghz.

altho i can play bfbc2 at 1.5v no problem. so could it be something else causing the problem?
