960T OC Help request

post #1 of 49
Thread Starter 
I'm at my wits end as I've tried various combinations but cannot get past 3.72GHz without pumping serious voltage 1.5+ through the vcore. This is my first OC on an AMD processor and was a little (though not too much) disappointed after seeing so many people say they could just put the multi to 20x @1.45V. Can't complain since the price was right and I enjoy overclocking. It's 6 core stable at 3.0Ghz as well... anyway to the point:

My most stable OC 24/7 capable
Have 2 cores locked so 960T x4
LLC, TurboCore, CnQ is off
240x15.5 @ 1.475V CPU
2400MHZ NB @ 1.3V CPU-NB and NB-V
Ram is rated for 1600 and is currently set at 1599 @9-9-9-24 2T 1.65v
Core temps are showing max @54* on IBT max setting and I know that the core temps are not always accurate on these chips but they stable out @45* and become more accurate? Correct me if that's wrong. Even with an offset watching the socket I'm pretty sure I'm within a safe range.

I've perused every 960T thread I can find/every guide I can find including Gappos/Dolk's/4ryan6's

I had a friend tech-savvy electrician friend check my psu (probably the weakest link on my computer, though I have a friend that OC'd his i7 to 5.0GHz+ with the same model) with his voltmeter and he said it was stable. I've also borrowed my friend's psu which is a Corsair 750(?)+ 80Plus certified PSU to rule out that as the cause.

The chip is CCBBE stepping if that matters?

Is there anything I'm missing? I feel like it's something I might be doing wrong and once I figure it out it'll be obvious. Or am I just being unrealistic? At the moment, I don't think it's a heat wall, just maybe I got a chip that's volt hungry? Any information you need I'll be happy to answer as well as any screenshots and any benchmarks I need to run.

Thank you for your time and consideration.

Ok..can you post your bios settings?You should be able to flip the multiplier up to 3.6 without changing
anything at all.CCBBE stepping?That's kind of odd..can you post a cpuz screenshot of cpu and memory,pls?Also..It would help if you fill out your comp specs in "rigbuilder"Don't bother with anything but the top line....but post all voltages and settings there, if possble

I hope this is right.

I'm trying to figure out how to get my bios to save the info to a flash drive to show a pic. Will post that if I can figure that out. UEFI is a bit different than I'm used to with a lot more settings than my previous board tongue.gif

Edit: You are correct, just did 20 runs on IBT at max at 3.6 just raising multiplier leaving everything on board enabled. Which is why I'm so confused on how I can't get it higher redface.gif raising it to 3.7 same default settings aside from multiplier tosses errors on IBT after 2nd run.

So, let's just have a recap here.

System works fine when the multiplier is raised but not when overclocked via ref clk increases?

If that is correct, then my answer is as follows:

Don't bother overclocking through the reference clock -- I've yet to see any reliable information that proves it to be in any way faster than overclocking via multiplier. On top of that, it is a pain to troubleshoot, and you always have to worry about increases to the North and South bridge cores, which is rare when overclocking via multi.

You have a Black Edition processor. Use the benefit of it's multiplier flexibility. You can also increase the NB and HTLink by their respective multipliers, so again, no point to increasing HTT.

System works fine until 3.6GHz with no voltage increase, fantastic. Stock is 1.4V on CPU. At 3.7GHz I have to increase CPU to 1.4375V. At the moment, I'm trying to find a way to make 3.8 stable, though I'd like to push to 4.0GHz+ if possible. The reason I even messed with the reference clock was because I had thought it might be able to be stable (naive I know) at a lower voltage than 1.5V+. When I did the multi at 240x and went to 3.720GHz that's the fastest stable clock I've got so far. As well as having my ram at 1600. Going past 1.5V isn't something I want to do on AIR and also isn't something I see a lot of until after 4.1-4.2GHz on the majority of 960T OC's that I find around on these forums. Everywhere I look I see "Push it up to 1.475 and hit multi to 20x" something my current build seemingly isn't capable of doing.

Again, I am new to this particular type of overclock. There are many variables that I need to take into consideration and I'm all for it being easier to check errors, so I'm not inherently opposed to raising solely on multi. I just feel I'm having a hell of a time getting this proc higher than what others have reported, so as far as I can tell, I'm either doing something wrong in complete ignorance, or my chip isn't made to get a high OC.

Wut,

i know Schmuckley and Ozzy were helping you but if you can't wait try these settings (DO NOT SKIP A STEP) . . .

- go back to bios and set everything to default
- disable the following - C1E, Turbo, HT, and Cool & Quiet
- set your vcore to 1.38v or 1.4v (try 1.38 first). Certainly quit if it asks for 1.47v.
- raise your Multiplier to 20
- the fsb should be at 200
- save and exit.

hope it boots. monitor your temp using programs like hw monitor. WATCH the TEMPS.

this is the only guide that we should follow . . .

I would like to iterate that I have indeed followed Gappo's guide already as noted. I have set everything to default, disabled CnQ, Turbo, HT is at auto, UCC is locked (overclocking only 4 cores at the moment), C1E is disabled.

I have raised the multiplier once again to 20x. It will boot (which gives me false hope), but it is NOT stable. I'm at 4.0 right now, on an unstable boot that I can guarantee won't pass Prime95/IBT. Occasionally, the screen flashes white quickly, then black, then blue screens to a stop code.

0x00000124 <- I believe indicates CPU-NB or Vcore voltage (correct me if I'm wrong)
0x0000001E <- I believe indicates VCore voltage
0x000000C5 <- Possible driver corruption?
0x0000007E <- Unstable OS (probably due to overclocking) - Now I could be wrong on these but as far as I can tell, these are correct.

I'm thinking maybe these people posting high overclocks are on unstable systems?

Am I correct in assuming that using memtest, Prime95, and IBT are good choices for stability?

I would like to re-iterate that I have followed the Gappo's guide.

It has not worked for me.

I am new to OC'ing, but I'm not inept.

I have had this computer for over a week. I would not post if I was not at my wits end.

I cannot find a solution.

Thank you for your time and consideration.


Edit: stop code to include cpu-nb on x0124. Log of progress. Boot into windows under 20x multi at 1.375 Vcore. Bluescreens to x00124. Increase voltage to 1.38--Vcore. Bluescreens to 0x00C5. Increased NB voltage to 1.25V... Will continually edit as they happen while under x20...

Edit 2: Now 0x00050 blue screen - 0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x <- is what I can find. I have increased the ram's voltage from 1.50 stock/default to as I have previously on the same routine solely decreased the frequency (first try) and then loosened the timings (second and successive tries) <<<<< IF you see me doing something wrong with the ram, feel free to point that out as I am most certainly not an expert at RAM with timings OC'ing etc.

Currently at auto they are running 1333 9-9-9-24- 1T.

mine won't pass prime as a quad at 4GHz with less than 1.4V. raise the vcore (just this and set everything else in auto). like i said, 1.47 is too much and is really up to you (or your sysyem) what is acceptable. the 212 should handle 4GHz no problem with reasonable vcore.

That's what I was thinking before I started this endeavor. I re-set everything back to auto (following that white rabbit on those stop codes) and increased the Vcore to 1.425.

I am comfortable with up to 1.55 rated voltage (I know no more than 1.475 is reccomended) as long as it isn't pushing temps past 62 core or 76 socket temp... I would love to just be able to increase Vcore to get this stable.


Edit: Vcore at 1.425, bluescreened on blend test stop code 0x00124. Increased Vcore to 1.4375V

Edit2: Blend test, core 4 dropped less than a minute in. Increased Vcore 1.4375V

Edit3: Blend Test, Core 4 dropped out right before stop code 0x00101. Increased vcore to 1.4500V

Edit4: Blend test, Core 4 dropped out less than a minute. Increasing Vcore to 1.4625V

Edit5: Blend test, core 4 dropped out in less than a minute. Increasing Vcore to 1.4750V

Edit6: Blend test, core 4 dropped out. Increased Vcore to 1.4875V

Edit6: Blend test, completed 9 tests, max temp shows 39* (assuming @44*), Prime95 stopped working. Increasing Vcore to 1.5V...

Edit6: Blend test, all cores completed test 1. Blue screened stop code 0x000101. Increased Vcore to 1.4875.
