Current Vcore is at 1.375 and VTT is at +300 PLL VCORE is 1.845 and IOH PLL is 1.80 QPI PLL is 1.20 Dim is 1.6

You say you are stable in all tests? What tests are these? I you passed 40 tests of LinX and 11 hours of Prime95 Blend that stop error is a software/driver issue.
The 0x00000101 stop error is just a crash of your game and not the whole system right?

Yep stable in Prime95 and LinX.

I'm starting to think this is a driver issue with the Nvidia drivers for my dual 275 ftws?
Every program and game runs flawlessly except flight SimX..... And it crashes the entire system -- BSOD.
It's a challenge to figure this out for me -- to say the least.
Before replacing the RAM I could not even start that game!
But on my ASUS board no problems whatsoever ......

Chronic420, here is a screenshot of my VCORE set to auto (and by screenshot, I mean a pic from my iphone):
www.dephekt.net/auto-vcore.JPG

I've raised my VCORE, one step at a time, up to 5 steps over auto (1.35000v). I've also raised my VTT from +100, +175, +200. My ram is rated for 1.65v, 8-8-8-24-74, which is what I have it set to. Also, according to your guide when I was following it initially, I was getting this problem at 2 and 1 steps below auto (and at auto).

Keep in mind, this is at a mere 160qpi. It seems weird that the numbers I see in other people's posts and numbers people use in several different guides I've read, for my same CPU and motherboard, just never work at all for me. I've never been able to keep stable settings overclocked, had this chip since May or so (iirc), following any guide I've seen. Not really a rant or anything, just weird.

Have you tried 3.2ghz and see how much vcore you need for it? You have a very voltage hungry chip. How are your temps at 1.35vcore? Is HT ON or OFF?

Yes it could be a "display driver tried to reset but couldn't" BSOD

Here is a question for ya!!!

I like the guide btw.

What is your opinion/suggest/input on 'this' instability issue....

100% stable, 50 LinX passes, Prime95 forever, etc. However, increase bclk even slightly, OR try to push the ram slightly, and NO BSODS or Crashes however cannot do LinX passes without errors?????

This is a big one for me and I still have not figured it out, thus why i am stuck at my current OC.

Ok I see your temps are very nice and low for such a high vcore. Looks like your chip is just very voltage hungry but not hot. See what 1.4v does to your temps. Also dont set VTT to auto if its showing 1.20v in E-Leet.  1.20v is the same as +0mv.

Well, here's the thing. If I run VCORE = 1.4V and VTT +100mV at my 148 QPI, the system crashes during LinX. If I go back in to BIOS and keep my VCORE at 1.4V and change my VTT to auto, I'm stable again.

Temps at 1.4V CORE and auto VTT are 74c 71c 70c 69c. Again, VTT at auto is 1.20 - 1.21V. If I put this up +100 mV, I lose stability. I want to mention this is all without vdroop.

I guess I didn't understand you before. Yeah, I could set VTT manually to +0 mV.

So far, with 1.4V VCORE and auto VTT, my LinX looks like this:

Size   LDA    Align. Time(s)    GFlops   Residual     Residual(norm)
24575  24584  4      252.133    39.2476  5.271611e-010 3.101634e-002
24575  24584  4      251.710    39.3136  5.271611e-010 3.101634e-002
24575  24584  4      256.671    38.5536  5.271611e-010 3.101634e-002
24575  24584  4      252.935    39.1232  5.271611e-010 3.101634e-002
24575  24584  4      251.722    39.3117  5.271611e-010 3.101634e-002

I'm running on air, my indoor temp is around 65F. I'm using an aftermarket CPU cooler, it's a Mongoose something, I forgot the whole name, but it's not stock air.

So at this point, should I be able to increase my QPI and go for a higher clock? Should I adjust my VTT to +50 mV when I do it? How far should I push the QPI initially above 148 before testing again for stability? Do I need to increase my VCORE from 1.4000V when I do this since I was stable at 1.32V with my 148 QPI?

Sorry for all the questions and thank you very much for taking the time thus far to go back and forth with me on this. I can guarantee I will always buy evga products from now on (this was my first evga motherboard).

Ok now that you've got that down, lets get you a nice overclock. Now you say you are clocked at 3360mhz right now with  160bclck right?
Turbo mode is on and HT is also ON. Execute disable bit and intel speed step disabled.

Try 163 bclck with your vcore still at 1.4. Bump the VTT up to +25mv and QPI PLL to 1.125. Run a few LinX and let me know how it goes.

Well, bad news. Even at a 152 QPI, I still crash like I did before, with VTT +25mV, vcore at 1.4V.

Yes, turbo is on, HT is on, execute disable bit and Intel speedstep are disabled.

In your last post, you said "QPI PLL to 1.125." Did you mean increase it by that much or set it directly to that? Because right now auto is 1.8V and I don't actually have an option low enough for 1.125V.

So just to recap what I've tried:

Stable
QPI = 148
VCORE = 1.4V
VTT = +0 mV

Unstable
QPI = 152
VCORE = 1.4V
VTT = +25 mV

Unstable
QPI = 148
VCORE = 1.4V
VTT = +100 mV

Well, I change the QPI PLL Vcore to 1.125V because I didn't see your "Leave it there" in time. But, I'm running:

QPI = 153
Vcore = 1.4V
VTT = +0mV
QPI PLL= 1.125V

One test has passed thus far in LinX. Temperature maxes are 75c 72c 71c 69c so far after LinX test one. Usually I don't complete the first test before my computer shuts down, so this is a good sign that it will be stable enough to move on.

Chronic420

Yes I dont think the QPI PLL will hurt at all. What is your ram ratio and actual ddr3 speed? Im assuming your ram is 1600mhz 8-8-8-24 by manufacturer spec.

Disregard my last on that. My computer crashed before LinX posted the results of the second test, so I'm still unstable at 153 QPI using my aforementioned voltages. It seems 148 QPI is the only QPI I've been able to run stable on for 20+ minutes.

To answer your current question, my running DIMM frequency at 153 QPI is 1221MHz (610MHz before the multiplier), running a 2:8 ratio. My ram is 1600MHz 8-8-8-24-74 @ 1.65V by spec.

Chronic420

Have you ever ran linx at auto everything to see if that crashes? Try running linx for 8 hours when you sleep tonight after you set everything on auto.

For the 153 QPI
Try increasing vcore to 1.42
Make sure QPI Frequency selection is at 4.8gt/s
Make sure CPU Uncore Frequency is at x16
PS Clock Skew = 0
VTT +0mv

I haven't ran LinX at default everything. However, I was able to run Prime 95 for like 12 hours overnight when I was running stable at 148 QPI with auto voltages on everything.

Chronic420

so 148 QPI with auto voltages everything and (with vdroop) passed 12 hours of prime95?

Im guessing this is what your settings were for that
QPI = 148
vcore = 1.32 (auto)
VTT = +0mv (auto)

That sounds right. It's been a couple days now, so I could be wrong, but that sounds right.

Great guide Chronic it will help alot of the new X58 newcomers out.

I am just now reading this thread for the first time and just finished the first page where there was apparently a lot of flaming going on.  I was wondering... am I correct in assuming that RJ replaced all of sylon's post with the one quoted below?  Surely,  sylon did not keep re-posting that over and over... first time I have ever seen something like this is why I'm asking.

This guide is full of holes and will leave the overclocking noob left feeling lsto and confused.
 
Of course they will asks questions.
 
Your gudie is far from complete.
 
Learn to overclock.
 
Your temps at that overclock are way to high especailly for the cooling setup you have.

 
Now to finish reading the rest of the thread where there seems to be some good info including the OP!  Nice work and a well deserved BR IMHO!!!
 

Chronic, I applaud you for the time and effort you put into the guide. I'm not new to overclocking but still managed to pick up a number of things from it.  You hints may get me stable at 4.2GHz yet! I'm sure there are many people still wrestling with their i7's but too embarrassed/proud to ask.
