AMD 1075t Overclocking

I need some help, no matter what I try I seem to get a core fail/error unless I'm on stock settings. Right now it fails after 25min of OCCT with multiplier of 14 and fsb of 286. CPU v is 1.45 CPU-nb voltage is 1.25, ram voltage is 1.7 (1.6=stock). CPU-nb and ht are 2280mhz, and ram clock speed is 1525mhz. Ram timings are at 9-9-9-24 until I can get a stable CPU overclock, but the default timings are 6-8-6-24.



Idk if there's anyway to make this work (settings last night before I found out my CPU-nb was too high):
CPU = AM3+ 1075t phenom ii x6
mobo = Asus M89GX
Ram = 2x 2gb g-skill 1600 MHz (running at 1525) 6-8-6-24 timings
HD = seagate barracuda 7200.12 1TB
PSU = 850w Thermaltake
PCI-e = ASUS 6870
Cooling = Corsair H50
Cased system = Thermaltake Case

4Ghz
Multiplier is 14
FSB is 286
Ht and CPU-nb are ~2578
CPU voltage is 1.45v
CPU-nb voltage is 1.35v
Ram voltage is ~1.71
Prime 95 12h stable
OCCT 2h stable

It worked yesterday, but I am now aware that CPU-nb voltage should not be as high as 1.35

It looks like you need to start back at the beginning. Start with these manual settings in BIOS:

HTRef: 210
CPU: 15X
vCore: 1.40v
cpuNB: 9X
cpuNB VID: 1.15v
HT Link: 9X
vDIMM (RAM): 1.70v
RAM speed: 667 (DDR3-1333)
RAM timings: 7-7-7

Test that out to see if it's stable and let us know what your load core temps are.


Also, a shot of your CPU-Z memory and SPD tabs would be helpful - I'm just kind of guessing at the RAM numbers.

My Mobo can't set CPU nb or ht link multiplier, my options are 1600. 1800 or 2000. (as clock speeds increase i have a lot more choices, for my stress test I used 2000 on both. I posted pics of the OCing options my Mobo has as well.

Images are attached For some reason they came out really big.. sry about that. Btw those lines aren't artifacts, just from my camera.

Just so I can look at them:
Once you attach pics you can use the paper-clip icon to position them in the thread. If you do that it will also resize them.
The paper-clip is at the top with the other add-ons: Font - Size - 'A' (color) - Smiley - Paper-clip

Edit:
From those pics set vDIMM to 1.55 and set timings to 9-9-9-25. You can go back later and play with RAM. For now, concentrate on the CPU/cpuNB overclock.

For the cpuNB and HT Link multipliers 2000 MHz = 10X, 1800 = 9X, 1600 = 8X, etc. A lot of boards do that and I usually include a note about it but forgot so you're looking for 1800 on both.


BTW - Here's a great little program for resizing pics.

Ok I have it now so it is stable for 1 hour Linpack, but cpucct it fails after 30 min with a core error (no bsod just a core error). Any suggestions for stability? Also, is the HT freq. supposed to be the same as the CPU-NB frequency, or is the HT supposed to be as close to 2000 mhz as possible? Also just for reference my ASUS bios is 1606
Pictures attached so you can see my current settings.

You can experiment with the HT Link but, from what I understand, most X6's like the cpuNB and HT Link the same. Doesn't hurt to try something different, though.

Did you change the RAM timings to 9-9-9? I ask because the vDIMM is still at 1.70.

Did you really need that much cpuNB voltage? Seems pretty high for the speed you're running.

How's your load core temp??

Timings are 9-9-9 2t forgot to change voltage back, about the CPU-nb voltage, I tried lower but it would either blue screen or error in 5 min, load core temps are 47.5C.

Did you start with the settings above and increase the HTRef a few MHz at a time?

When did you have to raise the cpuNB above 1.20v? I'd be more inclined to raise the vCore before the cpuNB.

I had to raise it once i got to around 3.8ghz

I'll try lowering my CPU-nb some and raising the vcore a bit.

When my CPU voltage is 1.47 (I tried raising it a bit) llc takes it up to 1.5360v on load, which seems too high.

Stable

Alright! I finally got it stable it seems my processor likes a cpu nb and ht frequency of 2670 instead of the lower 2403, it passed OCCT after I did 4 hours and 30 min. When it is on full load OCCT the cpu voltage goes up to 1.51 at max, when running normally idle/medium to mild usage the voltage varies from 1.46-1.49 due to LLC. I posted some pics of my settings, just wanted to make sure everything looked ok to you, thanks. P.S. it gets around 45C-47C at the very max when on OCCT load, even after 4:30

You really need your voltages that high for 4Ghz?

Maybe I was a little lucky with mine.. Here's my settings for 4Ghz

15 x 271 - 4065 Mhz
CPU/NB - 2710 Mhz
HT Link - 2168 Mhz
RAM - 1812 Mhz

CPUv - 1.390625v
CPU/NB - 1.20v
CPUVDDA - 2.55v
DRAM - 1.65v
HT - Auto
NB - Auto
NB 1.8v - Auto
SB - Auto
