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

[mrbungle]

Just picked up a 1055T and a Crosshair iv and have hit a wall at 258mhz bus speed

Very stable at these settings but cannot get the board to boot over about 260, just bluescreens on login. Have dropped the multi and it still does it. I doubt its the IV, maybe a duff cpu? All voltages are auto though ive played with upping the ones to do with cpu and nb and nothing changes llc is enabled

Any help be welcome

Why don't you try using the Turbo multipliers? Maybe 250*16

[mrbungle]

when i set it in bios or the clocking utility it doesnt change from multi 14

One or two weak core? You have to test each core one by one, then you find which one (or two) weakest. Pull down multi for them.

[ridney]

bsod are more like ram problems, try to replace the memory

[mrbungle]

ram perfect in a i7 system

will try mem test and see what comes of it

[crazydiamond]

what bios are you using?

[mrbungle]

used 5 and 8

[demonkevy666]

At 1.52V load (1.55V BIOS) and 4004 MHz, this 1055T system is pulling 420W. 247W idle. Talk about guzzling power... I'm thinking we may need to revise our 1.55V max for 45nm recommendation. That would be suicide for a budget board.

1. reason I'm using cool & quit now
2. how did you take out the gpu wattage I have no idea which one you used here? lol

Hi y'all

My first attempt at an OC so be gentle ! :p

water cooled rig i just built for the 1090T .. having a blast and got to 4.0 ghz tonite .. well impressed

* CPU Model: AMD Phenom II X6 1090T BE
* CPU Stepping: CCBBE CB 1013CPMW
* CPU Frequency: 4000 MHz
* CPU vCore: 1.425V
* CPU Multiplier: 20x
* CPU Turbo: Disabled

* Chipset/Socket: AM3, 890FX + SB850
* Cooling: WATER
* Temps: 31C Idle / 44C Load
* Operating System: Windows 7
* 32/64-Bit: 64
* Stable/Suicide/Untested: Untested

only tested a couple of hours in OCCT not the full 8 yet .. so untested



quick question .. I can obviously push the CPU and other parts Much further

but for 24/7 use BOINCing and Gaming ... where's a good safe place to stop the OC ? can it handle 4.5ghz 24/7 ??

thanks

OCD

Got it 8 hour small FFT stable at 4.0Ghz/1.488v.
Did a 3dMark06 suicide run at 4.3/1.616v NB @ 2762. Almost passed it at 4.4 with the same volts.

Is this a new CPU or a new result for your existing 1055T entry?

nice Yogi, low voltage sipper.

Use the Blend test to stress the CPU-NB as well.

My observation is I can have either 1600 ram+2400NB or 1333 ram+3000NB.
I thought initially the chip was somehow faulty or a ram incompatibility (Mushkin 996601). Not sure how to make a decision. I like games, and even then, the better choice would probably depend on the game itself.

[crazydiamond]

Sals, definately go w/ higher NB

also DedEmbryonicCe1, do your mainboard sensors not work correctly? i was thinking you might want to check the contact the heatsinks are making on the mobo since the temps seem kinda high

[DedEmbryonicCe1]

I also found that to be an issue. I can overclock my RAM to DDR1704 with the stock timings and voltage but only when my CPU&CPU-NB overclock is lighter. When I tried combining everything together I found that the same voltages were not stable anymore and I couldn't get my RAM to pass Memtest in Windows. That's why I'm still using the multipliers and not the HT reference clock.

I don't know if that one reading is accurate or not. The only part of the board I found to get particularly hot were some of the mosfets for the RAM slots so I put heatsinks on those. I have a 120mm fan blowing over the RAM slots and another over the mosfet heatsink. The mosfet heatsink was only "warm" to the touch during Prime95.

Here's one for the unstable charts on air.

[Yogi965]

nice Yogi, low voltage sipper.

Thanks, pretty big gap for 3.8-4.0 stable though :/

Use the Blend test to stress the CPU-NB as well.

I know, I was just trying to get my CPU stable first. Im gunna wait till I get my water loop setup before I do some more OCs.

[crazydiamond]

chew, any big differences you have noted between mobos regarding cpu clocks? like do any of them clock the same chip much better than the others, or less volts, etc??

[Chri$ch]

Is this a new CPU or a new result for your existing 1055T entry?

Look at the Stepping, its a new CPU

What was ambient temp on those test's? How low ambient temp can be
considered as aircooling? Might put my pc in to the freezer.. not!

My pb sp1m with 25c ambients is 4,6GHz, but that's with 32bit vista, havent
had time to test this little thuban with xp yet..

Got SF3D OC Inflection point LN2 pot last week so little more "extreme" testing soon!

maybe hes using that big indoor AC unit he posted the other day

The air coming out of my ac was 10c.........so itas possible with a bigger unit to get lower.

Chew is master, he has mostly the best AMD scores with Air/watter etc, if he want it
