Overclocking Amd phenom ii x6 1090t problems.

[OneMoar]

My 1100T easily does 4GHz @ 1.4v... I think his problem is the board. I mean his 1090T should easily do 3.6GHz on all cores. When he oc's he is just overclocking one of the cores, there must be an option or something to even the frequency between all cores, or select which cores you want to oc!

I think you need to overclock more cpus most phenom II's need 1.5 for 4Ghz and the Thuban is worse about it
here let me google it for you

I bought this one second hand from a guy who shipped it inside a sock (naked pins) rolled with aluminum tape, I guess I got quite lucky xD Regarding frequency or w/e, his problem seems to be able to overclock just one of the cores, which should not happen, he should be able to oc all at the same time!

Yes that's the problem, and i have searched and tested different things and i can't seem to find an option. Only option right now is to use software like Amd Overdrive. Even in the bios it says that it overclocks all cores, but in windows it doesn't.

On that Giga board set the turbo the same as your OC

 

[OneMoar]

always leave c/Pstates/turbo enabled unless you are having a specific issue

990fx is where its at for overclocking

 

[Johan45]

For PII/T I prefer 790

Modern AMD boards (900 series) are designed for FX in mind, so they are not so stable for Phenom II CPUs.

i used a 970 to unlock a 555BE to a 955BE

I have clocked both on 790FX and 990FX with no difference between the two.

Recap

Bought the Msi 970 Gaming, it couldn't overclock.

Bought the Gigabyte GA-970A-UD3P rev. 2 and it couldn't overclock neither, i contacted Gigabyte support who after some time provided me with a new bios so i can overclock.

I am finally at 4.0ghz 1.536V.
Max temp on core 48°C, and max 60°C Vrm using the Noctua NH-D15 After 30 min with IntelBurnTest.
I will have to test more, but it seems like this is the most stable for now.

It took me awhile of tweaking to get where I am with my 1100T, and its below what I expected.

Well, looks like you got it now. Problem is you had to do a lot to satisfy that chip, though... new board and cooling solution to be able to push that thing. /shrug

I had my 1100T on an MSI 990FX and it was solid as a rock

Got my 1100T to 4.3 IIRC, with NB of 3000. The NB OC helped more than core, but both together it was really not a bad CPU. Took some doing to go beyond 4.3 though, if I recall the voltages had to increase like mad past that point. I think it comes down to (obviously) the CPU in question, and the power delivery of the board. Again IIRC, at the level I had it OC'd it could draw over 200W. 970 boards like the OPs are usually cheaper and have lesser VRMs and cooling. I'd imagine thats whats limiting the OC here, as @cdawall all said. Also @Johan45 is right, the NB voltage sometimes needs to be upped (more so if you OC the NB, but can help general OC).

I don't know if it's safe, but i have my NB at 2.6ghz with 1.3V and it stays under 50°C

Had mine under a Corsair H100 at the time, don't recall actual temps but I remember it was in the safe zone. You mentioned getting a new cooler in your original post, I suggest doing that and getting an H105 or similar to handle the heat an OC'd Phenom II 6 core will produce. 50 is OK for now though, higher OC's I wouldn't recommend until cooling is improved.

Hope that helps

65C load is about when you should stop on the chip. 50C is fine if its stable.

 

[OneMoar]

its a phenom II ,the question is not whats safe but do you really care if you kill it

 

[Schmuckley]

I'd sell that thing and get one of these:

That's fine.Try to get CPU/NB to 2800-3000
Most Thubans need 1.47-8v for 4Ghz
cpu/nb=1.37v
NB=1.26v
Keep HT link around 2000-ish (but above)
^from memory.
You also might want to experiment with different multi/base clock combinations.
anywhere from 200-300.

I got my Northbridge at 2.6ghz with 1.3V i could maybe tweak it to reach 2.8ghz.
I got the Noctua NH-D15 cpu cooler which keeps the core temp under 50°C and on a hot day it reaches 55°C.
My motherboard got some decent 8+2 power phase and Vrm cooling which stays under 60°C on a normal day, here is a picture of the motherboard: http://www.gigabyte.com/fileupload/product/2/5194/20141121102844_big.jpg

My cpu needs 1.536V for 4ghz i have tried lower but it crashes after some time.

That's just how it is, then

I would point at the motherboard being chit.

I used a MSI 790FX-GD70 to clock my unlocked dual core 555 BE (4 cores) to 4100mhz on 1.475v using a Hyper TX3 (max temps 56c)

It's also dependant on your memory too, but this looks like a motherboard problem foremost.

 

[Recon-UK]

CPU Clock at 4.1ghz
North Bridge 3650mhz
HT Link 2600mhz
CL9 1600mhz Ram @ 1.5V

NB/HT link base motherboard voltages.

I relied heavily on the MSI board to deliver the clocks not the CPU multi and found it went higher this way, with just multi it hit a wall at 4ghz.
