I need some help with overclocking my cpu AMD Phenom II X6 1090T to 4.0GHz if possible my motherboard is ASUS M4A87TD EVO please help me

You set the Cpu multiplier to 20.... leave the cpu voltage on auto and run stability testing. Some of these 1090T's did not need much increased v-core to sustain 4ghz. Starts getting hairy around 4.4ghz, if you have the cooling capacity.

[Levent]

Do you have a beefy cooler? Because you are not gonna hit 4ghz with stock AM3 cooler. These chips cant handle high temperatures.

I have a pretty good cooler ngl it always kept the cpu under 36°C when im playing on high graphs n stuff

That doesnt mean anything. What about your temperatures with prime95? intel burn test? How are you reading the temperatures?

Im reading it with speedfan and i max out the speed of it aswell just in case i need it the cooler isnt a basic one

I benchmarked it a lot of times and the temperature rised only 1°C

The 1090T is a pretty decent chip and typically runs pretty cool. The less voltage you need to use the better.

I heard its really easy to overclock n such but is it normal for it to take time to start my desktop? Havent really overclocked in my life only watched youtube videos of others doing it

Could you screenshot temps after running prime95 for ~5 mins?

 

Board is prob bios crippled, i can make an ebb mod for it for higher fsb but dont expect too much

 

For safe volt since its 45nm id just follow intel spec for 45nm which is 1.6v, i doubt youll get anywhere near that though unless your cooling is extremely beefy, dont go above 2v ddr3, and since nb is 65nm dont go over 1.7v

 

 

For oc just crank the fsb as high as itll go then raise multi, higher fsb should increase performance so thats why i dont suggest oc purely with multi

Ill take a pic of it instead of ss if u dont mind

Yeah unless you have a 480mm rad there, that is not possible. You are either not reading correct values or your readouts are wrong.

Yeah you're right i just saw that the cpu temp is 50°C and ive been reading the gpu temp all this time because i tought it was the temp from speedfan. Sorry dudes i really did tought it was the cpu temp.

7m have passed since prime95 and the temp is 49°C to 50°C

@Ruvzyvat

DO NOT dump 1.6V into the Phenom II X6 1090T.

For 4.0 GHz, it DOES NOT need that much voltage.

If you need that voltage to get 4.0 GHz, you have a REALLY leaky piece of silicon.

 

A lot of software had issues properly reading CPU temperatures for AM3/AM3+ CPUs.

Because the temperature sensor was in the socket, and not within the CPU.

The IDLE temperatures were the most inaccurate.

At the time, HWMonitor and HWinfo gave temperature readings that made sense.

 

As for overclocking the CPU.

The easiest would be the adjust just the CPU multiplier -- and you can do that.

To get the highest overclock, you would want to use a combination of both CPU Bus AND CPU Multplier.

 

I owned a Phenom II X6 1090T from 2010 ~ 2013 (though I still have it in my display case).

Paired with an ASUS ROG Crosshair IV Formula 890FX motherboard.... and later with a Crosshair V Formula 990FX board when I transitioned to a FX-8350.

I was able to run 4.0 GHz with ~1.45V on the CPU Core Voltage.

4.1 GHz pushed the voltage up ot 1.48V.

 

I've done 4.0 GHz / 4.1 GHz using just the CPU Bus (250 MHz X 16 = 4.0 GHz), and just with the CPU Multiplier (200 MHz x 20.5 =  4.1 GHz)

Ill use the same like you and see if itll work. Sorry for wasting everybodys time here but im getting a hell a lot of fps drops recently and im on low graphics and everything may aswell try to overclock it till i start working in the summer

Keep in mind, you are running a lower-end motherboard, so keep an eye on temperatures and voltages.

Your motherboard use a 8+1 phase VRM with NO heatsinks to cool them.

The ASUS Crosshair IV Formula that I used has 8+2 phase VRM, and HAS cooling.

 

Uhh.... some things to keep in mind....what I can remember:

• Keep your HT Link Speed at stock, or close to stock....so 2000 MHz ~ 2200 MHz. Running that too high will introduce stability issues
  • The word was, never go above 2200 MHz
     
• Increasing your CPU-NB frequency will improve your memory (RAM) performance
  • I had my CPU-NB running at 3000 MHz, but to get that, I had to tweak the CPU-NB voltage (I was also playing around the NB and SB voltage, though)
  • 2700 MHz ~ 3000 MHz was the ideal range, but as you increase the CPU OC, it will be harder to keep a high CPU-NB frequency stable
  • Recommended safe CPU-NB voltage is around 1.3V, lower the better, only use as much as you need to keep things stable
     
• Keep the CPU Voltage below 1.5V if possible
  • Given the motherboard you are using, I would NOT try to push that far anyways
     
• Use the appropriate Load-Line Calibration setting that will give you the most stable voltage
  • Use an LLC setting too high, and our CPU voltage will spike higher
  • Too Low, and the CPU voltage can dip lower, making the CPU unstable
     
• You typically don't need to mess around with voltages like CPU-VDDA, NB, NB 1.8V, SB
  • Unless you are tying to push RAM overclocks
  • And trying to squeeze every last MHz out of your CPU

Thank you brother. Will do.

Thats max voltage not the voltage you need for 4ghz, good god how the hell do you interpret max voltage as voltage needed for 4ghz?

 

Been awhile since ive come across someone that interprets it like that so it was gonna happen eventually anyways

 

 

For safe volts since its a lowend board i doubt even maxing out the volts will kill anything, i suggest looking at max volt setting for boards like m4a89 then -0.4v for a safe volt, my p6t lets me set 2v cpu and 2.4v ddr3 if i enable the 0v headers so pretty accurate way to get safe volt since 1.6v cpu and 2v ddr3 is fine for maximum safe volt, i doubt youll need that high anyway so push them as far as you need to, conservative = rip overclock so dont be overly conservative

Aiite good to know that 

[Somerandomtechyboi]

Actually there are some exceptions that need -0.5v for safe volt, for me on x58 its qpi volt being 1.55v max safe and board lets me set upto 2v so beware of that

 

Also on cpu nb volt if its just nb volt it should tolerate atleast 1.6v due to nb being 65nm and seeing ppl reccomending not over 1.6/1.7v daily volt for p45 (also 65nm) but if its basically the equivalent of qpi volt on x58 then proceed with caution (treat it like the latter)

[Beerzerker]

Usually you don't need much over 1.40v's to hit 4.0 and be stable from a Thuban.
The less voltage you can use the better since these chips DO run hot under load, my 1100T showed me that long ago.

And I will say if you're needing 1.6v's to get 4.0 out of the chip it's not leaky, it's a shit-chip.
