DDR VTT Voltage Control 0.75v
NB Voltage Control 1.2v
NB/PCIe/PLL Voltage Control 1.8v
Only works when CPU clock ratio is set to [X17] and Northbridge set to [X12] or [AUTO] which gives 2400 MHZ either way.
CPU Performance Boost [Enabled] and under that listing it says
CPB Ratio [AUTO] 3400 MHZ
Turbo CPB [DISABLED]
Tried [Disabled] for CPU performance boost. No difference.
Any ideas?
Thanks,

EDIT: I filled out the Rigbuilder, but it isn't showing up.
The board is a GIGABYTE GA-880GA-UD3H

G.SKILL Ripjaws Series 4GB (2 x 2GB)

Arctic Cooling Freezer 7. Temps stay below 51 degrees C.

CORRECTION TO ABOVE: On [AUTO] the Northbridge frequency is actually 2000 MHZ and NOT 2400 MHZ.
1. Disabled CPU Performance Boost
2. Turbo was already disabled
3. Disabled Cool and Quet and C1E
4. Changed Ram Timings from [AUTO} to [Manual] and left the settings as is. For the GSkill Ripjaw modules # F3-12800CL9-2GBRL the timings is 9-9-9-24. Frequency has been kept at 1333 all along.
5. VCore 1 (CPU voltage) has been at 1.325v. vCore 2 (Ram voltage) has been at 1.49v Haven't changed these.
Tried 17.5 x 200 for a 3.5 GHZ overclock. Monitored with HWInfo, temps reached 51 degrees C running Intel Burn Test (5 passes) and 52 degrees running OCCT for five minutes. No crashes (BSOD). Ran Prime 95 for 5 minutes. No crashes.
Tried 18 x 200 for a 3.6 GHZ overclock. Ran Memtest 86 after I changed the BIOS. No errors.
Booted into Windows XP Pro and ran Intel Burn Test Temps reached 52 degrees C running Intel Burn Test (5 passes) with no crashes. Temps climbed to 55 degrees C running OCCT , but it crashed with a BSOD after 2 minutes.
Maybe 3.5 GHZ is my limit on six cores unless I am still doing something wrong?

Invest in a better cooler..thinking.gif: Sunbeamtech Core Contact 120?

So you don't think it is a ram problem, but rather a cooling problem?

The BSOD did seem to occur as I watched the temperature for Core 3 hit 55 degrees C.

Assuming that is too high, I can use a Hyper 212 cooler if I move the Ripjaws ram over to slots 2 & 3. Right now the Arctic Cooling Freezer 7 barely fits with the ram in Slots 1&2 and the Hyper 212 is much larger. I am using MX2 as a paste with the Arctic Cooling 7. I tried AS5 first then switched to MX2 and didn't see a difference between them so I left the MX2 on the CPU. It's on pretty thin.

I do have two sticks of Wintec Ampo if you think they would be better than the GSkill Ripjaws.

960t X5 200x19 @ 3.8 stable with +.5 on voltage, 6th core error in prime (#3) so disabled.
Will try for more later, sucks getting new hardware at beginning of work week. Computer and monitors at 250W @ idle. ouch.

200x20 is stable, 220*19 is not.

Biostar Smart Fan is the Devil, I gave up and just set to disable and let run full tilt.

Also might want to look at the temps for the VRMs. 55C for the cores (not socket) is high and pushing the 62C threshold. If you a prime blending and it's having issues with heat, then a large in place fft or linpack test would push temps even higher.

I hate how the new heatsinks mount on AMD processors, top/down instead of right/left. Unfortunately, without some major tweaking it's near impossible to get facing the other way. On top of that, most aftermarket solutions cover dimms 1&2, which makes removing them a pain.

As far as the ram goes, you can easily switch the divider in the bios and run the memory at a lower frequency (1066 or so) and that would let you know if there is a problem with it or the IMC communicated at such high speeds.

When overclocking, it's usually most beneficial to try and isolate one component and then work your way up. Memory is usually the easiest, so I'd start with that. See what the max speed the chips will run at. Then work on the Northbridge. Then the CPU. Lastly the FSB to fine tune the system.

Once you have the limits you can start putting it all together. In the processes, you'll find out what voltages are required for what speeds, and this can make troubleshooting later so much easier.

Going to apply some new settings in bios brb with prime results... thumb.gif
EDIT/UPDATE:
Tried the settings rdr09 gave me several pages back to no avail, even tried pumping 16v into the chip to see if I could get it stable just for a bit and still got BSODs however I was able to get into Windows and run Prime at 1.6v, I'm fairly certain now that my wall is at 4.1Ghz but I like things even so it'll stay 4.0Ghz.
Running Prime95 Listening to music and running a few programs in the background right now and I still have not crashed in 5 minutes. To me this is good enough. Upped Ram speed with my new Ripjaws set to 1800Mhz. biggrin.gif
Great news:
A friend of a friend was directed to my house to see if I could build him a computer for him and he decided that he wanted to go AMD and want's the chip out of my rig. Lol so I told him if the 960T he gets won't unlock I'll just give him mine and I'll get another one. He's also getting the same exact MB as me so this should be interesting. I'll keep you posted. (I will not be receiving the parts until probably 02/13/12)
UPDATE:
After 10Minutes of Prime cores 5&6 reported errors and the workers were stopped so I'm just going to revert my settings back to my proven profile. rolleyes.gif

Are you overclocking thru the multi or do you have the FSB tweaked as well?

I used these exact settings firstly, then tried tweaking voltages, even tried 1.6v on the cpu and was able to boot into windows but wasn't close to stable.

DRAM Freq (set automatically by BIOS): 1680

CPU Vcore: 1.46v
CPU/NB Voltage: 1.4v
DRAM Voltage: 1.63V (spec for my brand of RAM)
Both LLCs: enabled
the CPU/NB Voltage may be high. i read earlier in another thread it should only about 1.275V or something.
set at your own risk, all power saving stuff are disabled as well as Turbo, and watch your temp closely . . .gl!

Hey, just registered to post to this thread after seeing everyone's overclocks !

User Name: Lemon Jelly
CPU: AMD X4 960T Zosma
24/7 OC: X6 4425Mhz @ 1.62v
Max OC: X6 4425Mhz @ 1.62v
Unlockable: X6

It's prime stable at that, 245 bus and ~ 3gig NB + HT (didn't crash it so why not). At ~ 4200 it needs about 1.5v. Haven't tried with fewer cores yet, I quite like the 6 cores, but it would probably go a bit higher - I'm at the limit of core 5 which stops when priming at 4500. All under water and using CaQ to underclock for 90% of the time, max temp is about 52C from socket (silent rig so fans stay at ~800rpm). They're great chips and I got lucky after my x3 720 wouldn't unlock and topped out at 3600 with 1.5v !

I do believe this is the best X6 OC for a 960T yet... thumb.gif

Yeah, looks like you hitting the limit with the processor -- honestly, your CPUNB is way too high, though. 1.4v would be good for 3.2+, if your system could manage it. At 2700, you'd need about .075V or so.

If you're running 6 cores, I'm willing to be the VRMs are overheating; when the system crashes, is it an immediate BSOD or does it freeze up first and then eventually BSod?

Yeah, but using Q&C to unclock or K10stat, you can probably get the chip to run 4.8ghz PEAK, but not sustained. I can boot into windows at over 4.4, but it won't prime for more than 15-20 minutes before the system reboots.

So i replaced my 3rd and finale 960t biggrin.gif and this one loads in windows with 6 cores but i cant see the temps and i`m kinda scared to hit prime95 with stock fan tips ?
