AMD Thuban X6 OCing database

[thilanliyan]

I think we should have a database on this to share information.
Like the one at XS:
http://www.xtremesystems.org/forums/showthread.php?t=250607
Please provide as much information as possible and include a screenshot of a stability run if possible.

My own example (just copy and paste and fill in whatever you can and leave blank what you can't):
* CPU Model: AMD Phenom II X6 1055T
* CPU Stepping: CCBBE CB 1011BPMW
* CPU Frequency: 4004 MHz
* CPU vCore: 1.525V
* CPU Multiplier: 14x
* CPU Turbo: Disabled
* CPU NB Speed: 286x8=2574 MHz
* HT Bus Speed: 286x8=2574 MHz
* HT Link Speed: 286 MHz
* RAM Brand and Model: GSkill DDR2-800 + Kingmax DDR2-800
* RAM Speed: DDR2-760
* RAM Timings: 5-5-5-15-2T
* RAM Configuration: 2x2gb + 2x1gb
* RAM vDIMM: 1.95V
* Motherboard: Gigabyte 790GP-DS4H
* Chipset/Socket: 790GX + SB750, AM2+
* Cooling: custom watercooling
* Temps: 22C Idle / 40C Load (not sure how accurate the programs are)
* Operating System: Windows 7
* 32/64-Bit: 64
* Stable/Suicide/Untested: Stable

Finally got 4GHz OCCT stable, but ram is running under DDR2-800 and I had to manually change tRFc timings to get it to boot. I wish I could get PhenomMSRTweaker to work so I can have some idle underclocking too. I'm instead using CnQ but that only undervolts to 1.225v unfortunately.

Seems you had a little better luck then your Denebs, congrats!

Its good to see so many people enthusiastic for Thuban

I don't get it. There was all this hype right when they came out, and many people got these chips, or at least ordered one.

Where are all the replies ???????

 

[SpeedTester]

Just curious, why are you running XP 32 and 8gb of ram? Couldnt you benefit quite a bit
running win7 64?

My Chip 1090T will be in on Monday and I will post my results hopefully by the end of the night.

its 2 x 2gb, thanks, I fixed that.

As for why XP ? Win 7 is not cheap, and I have so many boxes. The one box its on (my 920) is a dual boot, and I usually use XP on it, as some of my programs don't work right under 7, and I don;t want to spend weeks re-installing everything. I just did a quick count, and I have 82 things to install, and thats probably low.

 

[SpeedTester]

I just picked up the OEM pro 64 for around $150. Your shiney new AMD chip wasnt cheap but you still bought it. ;^)

I understand the reinstalling thing. I'm the same way but I still think you are holding back your system from it's full potential.

bump... I can't believe there are only 3 X6 rigs out there...

 

[jchu14]

working on it Mark . I am having issues getting the 1055t over 3.7ghz, but trying!

 

[alyarb]

mark why don't you turn your multiplier down so that you can have a faster base clock? aren't you folding? you have a decent specimen and I'm certain your uncore can do 3 GHz or better at the voltage you're running now.

First, I admit I am a lazy overclocker.

So what settings do you suggest ?

Manimal, you OC is almost identical to mine !

I too am lazy mark lol

I couldnt get 2600 on the NB without a ton more voltage sadly. My ram is crap and I need two more clicks to get linx stable Vcore wise.

All in all the OC was super easy. My chip seems to run very warm since the Big Typhoon I had on it loaded coudlnt cope with the heat. Once I get a better cooler I may try to get more out of it but this is decent for now.

i was hoping you would mess around and get back to me. what is the fastest HT reference clock you have ever gotten on your board? it should be able to do at least 300 Mhz and there should be a separate setting for your northbridge multiplier. this is important because it directly relates to your L3 cache and improves overall performance.

 

[Kantastic]

I'll have a rig up in a week or so.

Same here. Waiting on a new cooler to help dial in the temps and voltage.

On a side note, looks like I've been running my ram in the wrong slots, I dunno if its AMD in general or this board in particular but the ram needs to be in slots 1 + 2 or 3 + 4, all the intel setups I've used wanted it in 1+3 or 2+4 for dual channel mode. seems to be running better now. I'm hoping my new CPU cooler (Coolermaster V8, picked it up for $20!) will be here friday

My chips doesn't seem as good as some of the other people's.

I'm Priming on 3.6ghz at 1.425v, I haven't been able to push through that. 3.7ghz won't stabilize even at 1.45v. Prime blend is heating up my temp to 56C w/ the stock hsf. This little hsf is pretty capable, but the fan is sounds like a vacuum at 5000rpm. I have a Scythe Yasya coming in tmrw, hopefully that'll give me a bit of a boost/peace and quiet. If I can't reach 4GHz, I'd really like to get to 3.7GHz. For some reason, I think 3.7GHz sounds a lot better than 3.6 GHz.

Oh anyone know what the difference bewteen 'VDDNB Over Voltage' and 'Chipset Over Voltage' is? I've upped teh VDDNB to 1.25 (from 1.75) and Chipset Over Voltage to 1.15 (from 1.1). Is Chipset Over Voltage controlling southbridge voltage? Which one should I be adjusting?

 

[T2k]

RAM brand & model would be also helpful...

 

[BD231]

VDD is the minimum amount of voltage going to a selected component (cpuvdd, nbvdd, ect.).

If you're stuck at 3.7 hopefully you just don't know what you're doing with that bios jchu14 . Pump the actual NB voltage up around 1.3v/1.325 and get your 4ghz!

 

[kstud]

You guys obviously know how to overclock but for those who doesn't here are the steps I took when doing HTT overclocking:

1) Set everything stock including ram voltage/timings, cpu, etc... and run prime to make sure it's stable.
2) Find the max HTT (aka FSB) by lowering the multi and upping the HTT and try to keep CPU clock around 2.8ghz (stock clock).
3) After finding max HTT, choose a multi you want to use (I chose 14 for the 1055t) and up the HTT (stock voltage) until it's no longer stable.
4) adjust voltage, NB, HT, etc... as needed for what ever clock you want.

My 1055t is priming @ 3.8ghz on 1.34 volts (stock volts for everything) going on 5hrs prime95 blend. Using a gigabyte 890gx and 4gb patriot 7-7-7-20 1333mhz. Will post back once I get my final clock with CPU-NB, HT, voltages, etc...

BTW, I only overclock on stock volts to keep temp/fan noise down.

 

[jchu14]

RAM brand & model would be also helpful...

Ah right. I'm using 2x2gb Patriot DDR2 800MHz ram rated 4-4-4-12 @ 2.1v. Motherboard is Asus M4A77D with 770/SB710. PSU is a 430watt Rosewill Green (ATNG made, copy of the Nexus Value 430). It's also powering a Radeon 5770.

I've tried setting the ram divider so that the ram stays within spec, didn't help.

Also, with more testing of turbo-core, it seems like my my overclock was limited by TDP (don't know if it's psu or mobo limitation). I turned on turbo-core and it seems to boost all the way up boost to 4ghz stabily at stock+0.025v (1.45v at bios and 1.45v @ load after boost and Vdroop, idle at 1.25v from CnQ).

I may stick with this setting of 3.4ghz before boost and 4Ghz after boost.

VDD is the minimum amount of voltage going to a selected component (cpuvdd, nbvdd, ect.).

If you're stuck at 3.7 hopefully you just don't know what you're doing with that bios jchu14 . Pump the actual NB voltage up around 1.3v/1.325 and get your 4ghz!

Thanks. then what's 'chipset over voltage'? Southbridge volt?

My 1055t is priming @ 3.8ghz on 1.34 volts (stock volts for everything) going on 5hrs prime95 blend. Using a gigabyte 890gx and 4gb patriot 7-7-7-20 1333mhz. Will post back once I get my final clock with CPU-NB, HT, voltages, etc...

BTW, I only overclock on stock volts to keep temp/fan noise down.

Thanks for the tips. Either you've got a gem of a chip there or I am unlucky (or my other hardware is lacking) because I can only get about 3.5GHz on stock volts.

 

[radaja]

there really should be some screenshots for proof.like at XS's they have categories for stable,unstable,untested.otherwise this is pretty useless.anyone can just post anything they want,and they dont even have to own a thuban.just a thought.

What's your NB speed?

Well, I did a quick test, 300 less than the current OC total speed, 2600 same NB, and I did have all the voltages up a bit, and it wouldn;t even post. Have to get back to work now.
