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

[BETA.]

Reporting back in. My 1055t did Prime95 stable 10 and a half hours with 1.55v/1.57v. LinX, full memory 20 pass test as well, but forgot to do a screenie.

Go ahead and set it to 2.5 as well as your CPUNB to 1.25-1.3. Then boot into windows and check stability.

I am going to try this with a much lower Vcore. i'll report back if there's good results.

1.57V for just 4G? That's insane.

[crazydiamond]

good temps for the volts though ive been helping him a lil through pm so hes starting to get it figured out.. id guess he'll get 4ghz stable somewhere around 1.5-1.52v

[Manicdan]

did we find out if amd overdrive let you use the higher multis for 1055T? if so that might help out BETA with using a much lower cpu voltage.

[Titan7171]

1.57V for just 4G? That's insane.

Id bet depending on the mobo it might be getting overvolted automatically through the mobo. If I set my voltage to lets say 1.4v I might see up to 1.45v if running prime. He should go over the voltages again my 1090T can do prime at 1.4v 4ghz.......didnt let it run for long but its just an example.

Ill post a pic in a minute im on my laptop now.

here cpu at 4ghz nb at 2800



setting my voltage to 1.57v for 4.2ghz and the nb at 3ghz look what the mobo does

Ambient temp is 21 degrees Celcius, so I don't believe the temperature the CPU is reporting.

This is all in a closed Lian-Li PC-A05N with an UltraKaze 2000 as intake powered by the CPU fan header. The fan runs 1100RPM idle and around 1700RPM under full load.

40mins may not be that long but it sure is good enough for me.

[biohead]

got mine today ...



hopefully a 4ghz chip as well.

[informal]

Good luck biohead!!! Post your results when you can.

Hey guys, looking for some insight with this issue I am having with my 1090T, taken from my cinebench benchmarking post...

Not sure why CPUZ has my clock speed/voltage fluctuating since I have C1E, Q&Q and CPB disabled in the bios? This appears to be an issue with the new asus bios, great.
Update: No matter what I set my cpu voltage to in the bios, it won't reflect the same bios voltage in cpuz or AOD. BIOS says 1.4V and AOD says 1.325...

To run at 4.0ghz I need to set 1.40V in AOD...

Hopefully Asus releases a fix for this.

[biohead]

Good luck biohead!!! Post your results when you can.

still waiting for that OCZ kit to arrive, got it from the FS section. so somewhere next week.

Ran all night (8 hours) at 4004 MHz on this 1055T. I had to set it to 1.55V. Lame. Turns out my board droops to around 1.51V under load, so no wonder I was crashing with lower voltage set.

On a side-note, here's a shot from my last DI run. This is the speed I played BC2 at, though voltage was higher I think.

Nice Prime.. that Dice OC @ 4500mhz and able to game cool...

Vdroop suc_ks Bal_s with Numerouse Mobos(ASUS inparticular) ,, If you Use Higher NBvid say above 1.35v (depends on NB freqency ) it will sometimes let you use a Lower Vcore For Prime. Seeing the IMC is what Hogs some juice once Prime kicks in the Heat.

Also look for a setting Like (VDD volts) in Bios... usually Runs @ 1.22v or Auto something like that .. Raising this to around 1.28v can keep the Vdroop more minamal.

The CPU Divider.. Sometimes a Higher or Lower Divider will have less stress on IMC = less load on same Voltage settings.

Its funny how a new chip makes everything New Again

Particle -- I will reserve this spot, and update with full info soon with CPUID and screen shots. Please wait to put your info in your official chart until I have the final, highest stable clock -- right now all I have done is very very simple. (EDIT: 1.45 V was not really stable, 1.50 V appears to be -- in terms of stable I am quoting Prime95 will test with Y-cruncher before I update the final report), EDIT2: Stable at 1.525 V requested in BIOS, 1.481 V at load. Prime 95 and Y-Chruncher 8 hour passed, Y-cruncher screenshot below.

Particle, why is your HT Link so low? Maybe that's causing instability?

[BETA.]

Hey all just reporting back in. I sold my previous 1015 batch chip on craigslist and was lucky enough to get a buyer within 2 hours of my posting. As some of you may already know, that chip took 1.57v to do 4 ghz. I got a lil guidance from crazydiamond but sadly this chip just wasn't having anything else. Anyways, after I sold the 1015 batch, I called up Fry's and spoke to the cage guy and he confirmed that the other batches they had were 1008's and 1010's, I went with the 1010. got home and popped the chip in and the stock VID is 1.3000v. Pretty good, I think? Waaaay better than the 1.425 chip atleast.

Anyways I managed to do 4.0ghz with 1.47v/1.49v prime95, small FFT's 10 hour stable and LinX full memory load, 20 passes. 286 bus speed, 14x multi with 8x on the NB and HT Link. 1.2v on the cpu nb, 1.2 NB everything else on auto.

I just wanted to update my situation, sadly though i forgot to take screenies of my 10 hr prime and 20 pass linx, but I got 3 hours of blend.

hi all i'm italian sry for my english.
now i have crosshair iii and 965 and 5970 sapphire. i use pc only for gaming. what do u think? i need to sell ch3 and 965 and buy ch4 and 1090t? it's better? i use pc with noctua nh-d14 and now i have 965 at 4000@.1475 - with 1090t i can overclock more? also 4200-4300 air mode? it's better for game? thx to all!

[richierich]

If you're only gaming your current system is fine.

[biohead]

hey richierich, i see that you're running a mugen 2 with two gentle typhoons, which is exactly what i'm gonna do. good combo, right?

i've already taped the short sides of the mugen 2 to eliminate airflow leakage for push-pull. i figured that would increase air pressure somewhat. thoughts?

[richierich]

How did you tape them? I figured that the typhoons were already good enough that I didn't have to do any kind of taping.

[biohead]

How did you tape them? I figured that the typhoons were already good enough that I didn't have to do any kind of taping.

transparant tape on both short sides. and it's not like the fans itself aren't good enough, it's just that i think this could increase performance a little. i'd like the air to go straight through rather than escape from the sides.

[richierich]

Oh I see now. I want to see your temps once you get your system setup.

[Particle]

Charts updated.

Particle, why is your HT Link so low? Maybe that's causing instability?

I try to keep it around 1GHz or so. Considering how unimportant HT link speed is, there really isn't any reason to push it. 800-1200 MHz is fine.

[Polizei]

So what's the story on stability? I ran prime95 for almost 5 hours for mine at 3800mhz and it was fine.

I also have an unstable/untested 4004mhz validation if you want that for the charts.
