Amd x6 1090t @ 4Ghz what voltage? - Page 2

post #11 of 21
Depends on the chip. My X6 loved 1.46v in the bios for 4Ghz stability

I have fix the themp error en starting overclocking.
Now i have bus speed: 201 Mhz, Multiplier: x18.0, Voltage: 1.45V makes ~ 3624.5 Mhz (3.6 Ghz Stabel).
But if i change my multiplier in x20.0. my system hangs when i start windows.. how can i fix this?

i have the same board as you, when you have turbo enabled , bios will show the vcore as 1.450v , however it only uses this when turbo is actually kicking in, its only at 1.300v when operating normally, however it displays the turbo mode voltage here instead. so i think you have tried to run your cpu at 4.0ghz at only 1.300v when you assume its 1.450v buts its not thats the turbo voltage, which is not going to boot , this took me ages to figure out. to check if im right simply turn off turbo boost in bios only and save and reboot , you will now see it only shows 1.300v for cpu cvore.

i am running mine now at 3.6@1.300volts all day stable. i have the turbo on still , at 4.0ghz , so turbo turns on and runs 1.450v and 4 ghz on the cores it needs. the cool n quiet also is left on to save power at idle, this drops to 1.2v @ 800mhz. it can handle 4ghz in turbo mode as it isnt using all cores at 4ghz and so doesnt get too hot. 53c max so far,

you can however turn turbo off and re-enter bios, youll see the 1.300 volts displayed now, boost this up to 1.450v and try 20 multiplier to get a constant 4ghz on all 6 cores, however i bet it will be stable in prime etc but will get too hot eg 58c, i have the hyper n620 cooler which is similar to your v8 but not quite as good. i can run 3.800@1.350v stable all day at 54c degrees (TMP01 socket temp) using 19 multiplier. however with a multiplier of 19 cool n quiet wont work , bios doesnt allow it to activiate , also if you turn turbo on, you can still set it to whatever speed you want but with the base at 1.350v you will find it jumps to 1.500v now with turbo mode and thats too high and hot for air cooling in my case. (turbo mode always boosts vcore by .150v from your base on this bios/MBoard.)

there are software programs you can use to have software versions of turbo and cool n quiet but i dont like them and they arent as consistent

so make the decision , stable all day on stock voltage at 3.6 and use 4ghz turbo and cool n quiet 800mhz, or turn turbo off and crank it to whatever speed you want boosting the vcore up . it will chew more power for no real reason tho. theres no real reason to run all 6 cores for a few 100 mhz more, not many progs use it, youre better off having the turbo on and a base of 3.6 imo.

these voltages worked stable for me 1.35v 19 multiplier 3.8ghz, and stock 1.300v for 18 multiplier.

use cpu-Z to see what the actual voltage is when in windows.

i also run the NB at 2600 and HT link at 2000, the NB only needs stock voltage of 1.200v to run this stable. tried 2800 with no noticible boost in performance.

hope this helps

I'm at 1.45 showing 1.5v in cpuid 24/7 and never crashed since . but temps get alittle hot if embient are at 22-30c smile.gif

I killed my AC units 2 weeks ago because my room was too hot and I let it ON since winter began . will have to buy a new AC .

what's good about it is I don't have to turn on my heater so it pays for itself.

just leave it to auto. it wont make a difference. they are all on in auto anyway, you would only use this function if you had a faulty core and wanted to disable it.
