Overclocking A E8600 Major Help Please

[s54m0]

Well, the problem is that every time I try to oc to 4 ghz (should be easy on a E8600 right) and run prime95, the second core keeps failing. Also, how are people overclocking while getting extremely low voltages? The lowest voltage for vcore my motherboard can go is around 1.25 and I've read people overclocking while getting less than 1.2?

 

I am using a Asus P5Q Deluxe MB and I have installed the latest drivers for it.

 

here is the link to the specs for the mb

ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler (I dunno how to change the speeds but it seems like it is on max)

http://www.newegg.com/Product/Product.aspx...N82E16835186134

 

The ram I am using is G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

 

specs:

Cas Latency 5

Timing 5-5-5-15

Voltage 1.8V - 1.9V

These are the settings I have tried:

 

CPU Ratio Setting .......... [10]

FSB Frequency .............. [400]

DRAM Frequency ............. [801]

PCIE Frequency ............. [100]

FSB Strap To North Bridge .. [Auto]

DRAM CLK Skew .............. [Auto]

DRAM Timing Control ........ [Auto]

 

CPU Voltage ................ [1.28125]

CPU GTL Reference (0/2) .... [Auto]

CPU GTL Reference (1/3) .... [Auto]

CPU PLL Voltage ............ [1.52]

FSB Termination Voltage .... [1.12]

DRAM Voltage ............... [1.9]

NB Voltage ................. [1.12]

 

Load-Line Calibration ...... [Enabled]

CPU Spread Spectrum ........ [Disabled]

PCIE Spread Spectrum ....... [Disabled]

CPU Clock Skew ............. [Auto]

NB Clock Skew .............. [Auto]

C1E Support ................ [Disabled]

Max CPUID Limit ............ [Disabled]

Intel Virtualization Tech .. [Disabled]

CPU TM Function ............ [Disabled]

Intel SpeedStep ............ [Disabled]

Intel C-STATE Tech ......... [Disabled]

 

I also tried:

 

10x400

vcore = 1.225

CPU PLL Voltage = 1.54

FSB term = 1.26

nb = 1.24

sb = 1.2v

and rest is all auto.

 

420fsb x 10

DRAM Frequency = 801Mhz

vcore = 1.35

CPU PLL Voltage = 1.50

FSB Termination Voltage = 1.12

NB = 1.4

sb = auto

and rest is all auto.

 

PLEASE HELP

 

 

EDIT:::

 

 

My last settings I tried was still a failure. Here was my config. I tried running prim95 with this settings and still, one of my cores fail. I have a VID of a 1.2500

 

 

Thanks.

Welcome to OCC

It might be a good idea to start back at stock (10x333) use 1.25vcore and set your RAM to 2.0v and be sure all of your hardware is stable.run memtest overnight to test your RAM.

Run prime95. After your RAM passes for at least 8 hours(24 hours is what I would let it run for), be sure to check temps using coretemp or realtemp.

 

Sure its a long time but isn't it a good feeling that you know without a doubt you have a rock stable machine?

 

I like to do this so I know that there are no issues such as a bad RAM stick or something. Then I can confidently start clocking and get things rolling.

 

A lot of things can be set wrong and the only way to find out is process of elimination. Randomly entering numbers in BIOS may work but you won't really know for sure what exactly are optimum settings unless you establish a baseline at stock and work your way up.

 

 

Just because Joe Schmoe says he can run 4 ghz at 1.25v doesn't mean anything. Heck I can tell you my chip runs at 5 ghz using 1.0 vcore. Doesn't mean its true and you will never be able to prove it. What you can prove is what your PC can do and I am telling you this is a good way to go about doing it.

 

Read the guides, they have a lot of great information and it would be in your best interests instead of just guessing and getting frustrated.

 

Good luck.

Kingfisher has a good point. Make sure you have a solid rig at stock settings. You may have a bad Core 2 with stock setting, but you would never know unless you checked. Make sure you take solid notes when you work. Change one item at a time and record what was changed and the results of that change. This will make it easier to go back and fix problems.

 

Try upping your FSB Termination a little. I'm not the best of help, but that seems a little low to me in all of your settings. Wait for some more serious OCers to get in here.

I agree with Kingfisher.. My e8400 wasn't such a great overclocker.. Compared to others which could easily do 4ghz on 1.35v or lower.. I couldn't even get 4ghz stable with 1.45v.. So your best bet would be to check for stability first like what Kingfisher has pointed.. Try using 1.3v for fsb termination voltage cause it helped my rig get stable hope it could do the same for yours..

Thanks for the help!

 

What setting should I run on the prime95? Also, is there a reason to run the ram on 2.0?

 

Thanks!

I always like to run blend test.

I run my G.SKILLs at 2 volts.

You can try using other voltages if you like.

I love my E8600 it runs great in my setup. With some watercooling mabey 5.0Ghz

Most people would recommend running blend test cause it totally works your ram.. But for me.. I can't run blend as it totally uses 100% of the ram.. Reason for running the ram at 2.0v is just to reduce the variables in oc'ing.. But u can run at 1.8v if you do not intend to oc the ram..
