I am thinking that I have absolutely no luck with overclocking. Every guide/template I have done results in Prime crashing or my computer not booting. One of my sticks of RAM went bad and I am back to stock config running 2/3 RAM. 8GB instead of 12GB
All I want to do is get a 4.0Ghz clock and maintain a cool system. My temps are currently:
Ambient air 75-80F
Using highest core in CoreTemp
idle /load
28-35C/49-52C
I see other H2O setups with lower idle temps. If I look at the led numbers on the mobo, it reads 14-18. Which one do most people use?
Could using 2 sticks of RAM hurt my overclock?
Are there any templates that anyone is using that is rock solid and fits my mobo/cpu/RAM combo?
EVGA FTW3/i7 970/Mushkin Blackline 12800, 9-9-9-247 1.65V
Also anything else anyone can think of for help would be much appreciated.
thank you

I used this guide to overclock my i7 920: http://forums.evga.com/Simple-X58-Overclocking-for-Dummies-m81651.aspx it may be useful for you. Usually what I do is drop the cpu to stock with vdroop off and set the voltage and vtt to stock (not on auto). Then I increase the freq by 100MHz increments. Testing stability with 10 passes of linx /or intel burn test for every increase. When it bsod's I increase the vcore or vtt (depending on the type of bsod) by 1 increment and try again until it's stable. Repeat the process until you get to the freq you want. Idle temps depend on your ambient temperature. (hot ambient= hot idle, cool ambient= cool idle (usually). Using 2 sticks of ram might improve oc potential and temps since it's not putting as much load on the IMC. Hope this helps you in any way.

Thank you!! :) I did the incremental like you suggested and I think I found a happy medium between an OC 3.75 and temps. I will run Prime the rest of the night to test stability..but my "highest core" idle is 40C and load is around 60C..Ambient temps 76F. Hopefully this stays good throughout the night.

I moved it to 3.73. It did not make the overnight run. My RAM timings are different from the printed timings on the RAM. If I get the timings correct on the RAM in the bios, will I be able to either reduce my cpu voltage or increase my overclock at the current cpu voltage?

Set the ram to default spec. And no, it probably wont make any difference to your oc.

From a quick glance the VTT is way too high and probably causing the stability issues. 1.3v on vtt is considered high. Try for bclk around 175 to 195. Remember that some chips like odd multipliers and some like even multipliers. If you have the cooling you can use more vcore. And NB can go up to 1.12-1.14. Keep the memory at low multi until you get the CPU stable and dialed in then raise mem multi slowly after that.

Good point Nathan, also, some CPUs have a BCLK hole, no matter what settings and voltages you apply, some CPUs just will not post, or stay stable at certain BCLK's, and it varies. I have seen it personally. My old X58 sat strong all day at 4.2, when I tried pushing it, at BCLK 197 I had a hole until like 205 or 206, above that, same voltage it worked again, rather odd. 900 series procs can have some really oddball personality quirks at times.
Also, when you left Prime running, which Prime test were you running, Blend, Large or Small FFT's? Did the program crash, PC freeze, BSOD, reboot, or did you loose 1+ core(s) during the test?

wow,didnt know that(Holes) maybe that what happened to me when i was trying to get past 4.2 on air. Might have to try it again this winter when its a little cooler out. Not to be nosie or get off subject what did you get your I-7 920 up to above 4.2. I got to 4.4 and ,figured I would mess something up and toast cpu. THX Dave B

Hello and ty for the info. I lowered my VTT, increased my chipset voltage. I moved my OC to 160 or 3.8. It seems to be doing fine and 10min stress test went ok. When I run prime, I use the blended test. So far, the only thing that crashes is Prime95. I just close the error message, windows is just fine, and any other programs (chrome) work just fine as well. My bios settings are below(except changing to 160 freq).

For quick and dirty 4ghz try 1.33v on vcore with 185 bclk and 22x clock ratio (don't change anything else from what you have now). After that if you crash you can slowly bump up vcore to get stable (watch temps though). If your stable with that vcore then you can slowly back vcore down to see how low you can run vcore at with those settings. Depending on your cooling you should have no issues getting 4ghz on any LGA1366 chip.
Edit : You might also need to lower the memory ratio down when you change it to the 185 bclk

what is the difference between using 22x clock vs 23x vs 24 or anything else?

If you look at your first pic it is what gets you the Target Freq.
185 x 22 = 4.07Ghz
you had - 156 x 24 = 3.7Ghz
I was saying earlier some CPU's like odd and some like even more, and some chips don't care. If you have trouble getting 22 stable you can try 21 or 23. And just adjust the bclk to fit your target.
I fine that the multipliers are just hit or miss some work well some may not. As for bclk getting to 200 can be hard to do on some chips. But I seen many people in the past with 4.2ghz with 200 blck at 21x. That was a pretty common overclock on 45nm CPU's. The i7 970 you have there is 32nm so should be even easier to get it over 4ghz, which you mentioned is your goal in the first post.

thank you, do you think there any kind of benefit from being at:
185*22= 4.004
vs
168*24= 4.032
I was just curious from temps/longevity/performance perspective

It won't really make any difference, just go with whichever is more stable.

Yeah it won't matter until you get to the point where 24 ratio is not enough. Then you will need the higher bclk.

so i was trying some different settings. at 3.8 my system:
liked 24 x 158
did not like 22 x 172
Also,
I think I will stay 3.83. I like the temps. I tried going to 4.0 and slowly increasing the voltage and could not find a sweet spot and I did not want to go up to 1.25.
Some further questions.
1. Why can I run my setup all day with no problems(including minor stress testing 10-20min in Prime95), but if I test it overnight with Prime 95(blended), it crashes?
2. Is 3.83Ghz enough of an overclock for ideal performance of video cards? GTX 670 4GB single/sli up to 780ti sli?
Thanks again for all the help.

If you can do short stress test and can't last through longer stress test, then you might just need slightly more vcore. 1.3v for both NB and vcore is not that big of a deal don't have to worry about staying at 1.25v. If you set the board to Auto vcore it would probably go higher than that 1.25v anyway. Your actually being safer than then the board auto.

Personally, I say the water isn't a bad idea, but, the temps are not bad, if you got a quiet fan and aimed it at the VRM you should be fine, something like a Noise blocker.
Now for your testing, I would say that you have passed one of the tiers of stability testing. I would also do either game benchmarks or overall system benching like 3d Mark or Valley, then the final stage is LinX/IBT, put it on Max memory and 20 passes and let it run. that is the true test. I do this conglomerate of tests as I have seen systems that are stable on one not another, and usually when you can do all of these, your cooling is solid, and your CPU/RAM will be fine for all, be-it gaming, streaming, number crunching or A/V encoding.

Nice, definitely need to test longer than that though. You probably won't have much temperature stability issues until you get it up to 80c. Might as well go little higher and get it to 4Ghz threshold.
