E6600 not stable at 3.0 I need help

I followed wussy's guide to do this.
It's my first time trying to OC. Please be gentle.
here are the parts:
e6600 & big typhoon
p5n-e sli
8800gts
G.skill ddr-6400 F2-6400CL4D-2GBPK
Antec Neo HE 550W.

I tried to Oc to 3.0~ and it's not stable. Randomly got BSOD. I think it's the ram's problem.
here are some screenshots I took. Please give me some suggestions what I should try to do. Thanks alot.



Summary of what I did following wussy's guide:
1. Disable all the things that wussy mentioned in bios
2. Set ram timing as 4-4-4-12 ( either 2t or 1t wouldn't be stable) @ 2.013 volt.
3. Unlinked. Set vcore from auto to 1.4v
4. Increased Cpu's fsb to 1332mhz (ram still at stock @ 800mhz
that's basically what i did. I need your help.

If you need any additional information please let me know.

I am running @ 2T. Correct me if I am wrong, but if i put at 1:1 then would it be like 3.6Ghz? I am afraid reaching 3.6 is gonna be hard and cpu would be a bit hotter. I just need it to be stable @ 3.0~
as advertised the G.skill memory I bought can run @ 4-4-4-12 2.0~2.1v
Thanks for your help.

I have the same problem with my E6600, random BSOD.
But i use 4 x 1GB DIMMs 667Mhz memory.
This is how i think you should reach stable 3.0 Ghz or FSB 1333.
For the E6600 3.0Ghz isnt much of a problem to reach easily with almost no raising the CPU voltage.Do the following :
Raise the CPU voltage in your bios 1 or 2 steps.
Raise the voltage of your ram to 2.00 or 2.10 Volts
FSB/ram ratio must be set at 1:1 and when you have done so check if your Ram runs at 667 Mhz (FSB 333Mhz x 2 = 667Mhz speed of ram)
You have good quality ram so you can set the timings at 4-4-4-12 at 667Mhz or just to be surely save or still get unstable results try timings t 5-5-5-15.
the greatest "bottleneck"when overclocking in your system is your MCH because the only tthing that is pushed a bit is your memory controller.Raise the voltage of your MCH to about 1.38V.
(3 or four notches from default on your MCH voltage.)
When you have done all this your system should run as stable as a rock.
Good luck!

Default voltage for E6600 is around 1.25V.I suggest setting it at about 1.30V.The less volt it runs stable at, the better.More voltage means more heat and heat kills electronics in the long run.
MCH is NB voltage yes, so this should be the most "stressed"to obtain 3 ghz and needs to be raised a bit.
your ram running at 333Mhz (667)instead of 400Mhz(800)doesnt impact performance not even in a million years.800Mhz ram is mostly used for extreme overclocking with FSB to 400Mhz or higher, then it is worth having 800Mhz DDR ram.For overclocking to 3 Ghz, 667Mhz ram timing is even better because it will run synchronised to the FSB and processor delivering its data, so FSB/ram settings at 1:1 is the best you can do.Chnging ram timings doesnt help so very either, but will get better results than raising ram speeds.Most memory work in dual channel so bandwidth isnt a problem, latency can be helped a little bit by adjusting timings of ram.for your ram i should try 4-4-4-12 because i think it can manage those timings stable.If unstable at these timings try loosing the latencies to eg 5-4-4-15 or so.Performace advantage from better timings: expext 1-5% performance increase so up to you if you crave this performance over stability or not.(hopefully it will get stable at these better timings)
Im still trying to get my rig stable :-( hopefully i will succeed!
Good luck!

I think it is stable for now. Ran memtest overnight for 12 hours and passed. No more BSODs. I have one more question regarding the temps.

I have googled and read the temp stickie so far, but due to my bad English I dont get much out of them, so I am asking for experience users to see if these temps are fine @ idle? for some reason TAT doesn't work after so many tries and which temp I should be looking at? Thank you for your replies.

What should I do because TAT doesn't work. :x

The system is stable. Thanks to all. memtest 12 hours no errors, orthos 8 hours passed. The only thing im worrying about is the temp as i mentioned. Those numbers are weird. Tat doesn't work. I already googled the error, but couldn't find the solution.
I have tried Core Temp, Asus Probe, speedfan,everest,pcwizzard ...

I have a similar configuration same C.P.U. & R.A.M. but I have a Intel 975 DFI Mother Board but maybe my Info will help. I run the ram 1:1 or 533 MHz Strap @ 390 Mhz X9=3.5 GHz using a Zalman 9500 LED 5-5-5-15 @2.2V 25C now 58C on Othhos stable for 20 Min. I lapped the Processor and am giving it 1.44 Volts Weird CPU-Z does not show Command Rate for me.



I was looking for ways to keep this Processor cooler than 66C at full load under Orthos. I found a nice muli-Pack of Fine Sand Paper at a local AutoZone so I picked up a pack. I read to do it on a piece of glass to keep it flat so I used a piece of Mirror I had to put in the bottom of cases. I started with 800 Grit and found the Integrated Heat Spreader (I.H.S.) to be quite uneven leaving the nickel on the center at first then in two corners. After mostly filling the 800 Grit piece of paper with copper dust I moved on to the 1000 Grit. I moved the C.P.U. in small circles turning the C.P.U. every few strokes reversing direction as well. I used Brass-O to polish the I.H.S. till I could see my face in it. This lowered my C.P.U. Temp from 66C to 64C @ 351X9=3.16 GHz...Hey It's still faster than a Core 2 Extreme X6800 For 1/3 the Price!

I had too much Thermal paste after a reapplication of AS5 in the amount of just a small piece of rice I got 60C then I put my System in an Antec 900 Case and got 58C Under Load even at the incredible OC of 3.5 GHz.

Dude! Vmem 2.1 Vcore 1.4 Vnb 1.65+ add a 40mm fan to the nb

I watched Core temp as I ran Orthos

If you look at the pix mine is around the same @ idl in term of temp, so I dont have to worry about the temp then? thanks.

I opened Orthos for over 30 mins I dont know if it's long enough. Here is the result.


Been watching. The temp seems to stay there. Not going higher

I accidently hit stop right before taking the screenshot. I dont wanna run it for now. I hope you can see the picture

You have a pic of your memory settings? I have the same ram as you and i have it set in the bios to 1:1 divider with a 375x8 fsb but when i open cpu-z it shows me at a 5:6 divider and the memory is at 400mhz....

Your temps are banging. Happy clocking!

Hay 20033,

The biggest thing that held me back was the MCH voltage. Once I raised it alittle the rest came easy. I pushed the Vcore some, and then set the memory to 1.1, and she runs cool and very stable. 35c idle and 45-47 load

I was using smart guardian it came with my DFI Mother Board it reports 9C more than Core Temp. Do you think it's closer to the truth?
