I have no idea why, anyone have any ideas?
I didn't increase voltages at all either
I had the HT at 1920 and the memory at around 1170mhz (down from 1333)

that is not very accurate... at least we need to know what clocks, NB clocks and what CPU and CPU/NB volts you used... ram voltage also couldnt hurt, NB voltage, VDDA and so on would be a welcomed present too

Good thing I wrote it down :d
DRAM Voltage: 1.500
DDR VTT = 0750
NB Voltage - 1.300
Sideport 1.600
nv/pciE/pll - 1.800v
CPU voltage - 1.3500

and I was trying to get about 3.5ghz at the time but then it just didn't boot anymore. Not even a boot then blue screen. I had to remove the cmos battery twice and hold the power button for 1 min+ twice, re-installing graphics card, cpu and RAM for it to work

I was reading articles/watching videos about overclocking Phenom II X6s and people were saying how 3.7ghz is achievable "straight out the box" with no voltage changes. Quite annoying too cos I've got the 95w version as well

that's thermal cut out caused by to much heat

Oh I thought that too, but seeing as I didn't get into windows I ruled it out

put the ram voltage to 1.6-1.65, the vtt voltage on auto, the NB voltage can be left like that, but you also can try auto to see if there is a difference... sideport is only important if you use the onboard VGA, and can be set to auto... you also better shut the onboard VGA off as long as you dont use it, keeps the NB and VRM a good tad cooler
PCIE voltage should be on auto.
The CPU voltage is alright for 3.5ghz, if you dont have a pretty bad example of an x6...
but i dont think that!
i think you have forgot to set the CPU- NB and HT clocks correctly...
you have a x6 Non- Black edition, which you can only clock up to 3.5 ghz if you up the HTT to 250.
With the HTT at 250, and the HT and NB at stock, it should equal to 2500mhz NB and 2500mhz HT (max NB and HT multi are 10x on locked X2,X4 and X6, i think)
i know, that most of them have problems to be stable, and some, to actually boot, with stock CPU/NB volts and NB clocks past 2400... only the very good ones will do that without a problem.
You probably dont thave the CPU/NB option in bios, you can only access it by using this, when beeing in windows (you should better look for a windows based FSB changing tool for your board when trying that, it can be the only way for you to get 3.5 (and probably more) actually stable
HT at 2500 doesnt need to be problematic, buts its unnecessary,except once you really come to tweak the last bits of performance from your rig.
For finding Inital stability, you should dial it back to 8 (2000HT) or 7 (1750), depending if the former is stable or not.
try this and then report back, if anything changed

Doesnt necessarily need to be... if he clocked the NB too high,at too low volts, exactly that can happen... for me it was only a few cold resets at worst,i admit,but sometimes with the Bios completely resetting and signaling a HT transport sync error... the temps should be alright if he didnt made a fatal error upon application of the TIM.

lovely stuff
I'll try it out tomorrow man, I'm going to bed now
I'll update when I give it a go

windows still didn't boot with THESE settings

these are the settings I tried
as you can see the HT link freq = 2000 (same as default)
and the memory clock is at 1332mhz
and the DRAM is up to 1.605v

turns out this whole time my 1333mhz RAM was running at 1066mhz

also how do I disable the onboard gpu?

you should up the cpu/NB vid to 1.2-1.25v, or put the NB down to less than 2400mhz... that should make a difference

in your bios there should be an option to shut off the onboard VGA, but its not in M.I.T., as far as i can tell

[El_Mayo]

gonna change that now, I'll edit when I try it ;D

[El_Mayo]

Okay, still not booting windows with THESE settings



it's rather annoying
I think the default HT link frequency is 1600mhz though, maybe that's why it's not booting when I use 2000?
also by default my cpu is undervolted from 1.35v to 1.30

then, you can try for more Vcore , say 1.4, and lower HT, as you say.
if that still doesnt work, try to dial down the HTT until it works... 225 probably will.
if that works,your board is probably a bad HTT clocker,which cant hold the 250 stable, and which efficiently puts a hard lock to the progress of your OCing attempts... you then only can try, to give the NB more volts, to see, if it lets you clock the HTT higher.
Or,you exchange the processor to a black edition or the board to one, that can clock up to 300 HTT

To disable the iGPU go under the IGX Config at the top of the MIT menu. As for booting try setting the NB to 1.35v, not the CPU-NB. My MSI 890GX needs roughly that much to boot at 250mhz HTT.

ah, there was it! nearly hidden,at the top! my fault!
yeah, what he said!

My pc doesn't boot windows
but it does the post beep and just freezes on the motherboard menu

I press DEL but it never brings up the BIOS
I give up on overclocking
I might just undervolt at stock speeds and live with that (when my pc springs back to life)

Reset CMOS, or remove CMOS battery.

~~~~~~~~~~~

Figure this one out:

My 1090T will do 207 x 19.5 Prime95 stable (209 = unstable for core 1), but only in AMD Overdrive. My BIOS won't let me boot up if I dial in this setting, giving me an OC unstable message. Can do 200 x 20 no problem though.

HT: 207
CPU x19.5 @1.5v
CPU-NB x15 @1.35v
RAM x800 @1.65v

I've got a 1055T :P
I'll try removing the battery and booting

edit: oh that did the trick :P
I did a tiny overclock 3.01ghz (couldn't resist) and it seems to work fine
I'm running prime95 for a few hours to test now

[erocker]

Overclocking a 6 core on a motherboard with 4+1 phases isn't recommended. Just don't go pushing a lot of voltage.

what voltages and clocks youre at atm?
as said, it can be, that your Board/Proc can not clock the HTT very good.... if you want to keep your board save too, set your board to stock clocks and volts (except for the memory, that you can set at 1333 1.55-1.65 fixed) and then try to volt down the processor as far as possible with stock clocks... from that point, you can start your OCing the best

Definetly not more than 1.4v... rather less than 1.35. i can also second that

You just need to set your HTT (or processor clock on the GB board) to 250 like you did before but change the multipliers so that all the clocks are at stock or below. Leave the memory timings on auto and change the multiplier so they run at stock speeds. Leave the stock voltages at stock except for the NB (890GX chip). Set it to 1.35v and see if it boots.

If it doesn't boot after that then boost the NB volts up one increment to the next "+" setting. Keep doing that until it boots.

Eventually you will find the volts needed to boot at that speed then you can start messing with the other multipliers.

I won't increase the voltage above 1.4v
what's 4+1 phases?

well atm it's 3.01ghz
I'm using the voltages on AUTO so I don't really know man

Definetly not more than 1.4v... rather less than 1.35. i can also second that

well prime95 keeps failing on me atm "HARDWARE FAILURE" and all that so I wanna get this overclock STABLE before going higher

4+1 phases means 4 voltage regulator packs for the CPU, and one for the memory
as i said, use stock clocks, and try to undervolt, step by step, until it gets instable... from the last point where its FULLY stable, you can start to clock up/volt up then

While my 890GX Gigabyte board doesn't work, for a 4+1 board that mother is one heavy sob. Heavier then even a MSI 980a (which is 8+2) or my beloved Asus P6T6 Intel board. I about dropped it when I first took it out of the board because I wasn't expecting the weight.

While it maybe 4+1, it sure is not like the MSI 890GX 4+1. I'd trust that Gigabyte board long before any MSI board.
