So this is the thing: The "dummy OC" option in the BIOS seems to not work for me... I made sure it said yes, made sure I saved, but it's still showing up as 2.67GHz. If someone can tell me if there is anything different I have to do for that to work that would be awesome.. but either way my goal is at least 3.5GHz, and hopefully 3.8 or even 4.0 and I heard this was very possible. I would really appreciate it if someone can tell me EXACTLY what I have to change in my BIOS and or ELEET software to achieve this. I have never OC'd or anything and just want to get this done right now, Don't really care if I learn something just want my comp to be at 3.5-4GHz, so if anyone can provide a step by step DETAILED instruction, I will prolly succumb to having your babies. Thank you!
 
OK. I don't have one, but this should all be right - I'm looking in the EVGA manual to find where your settings are (I have the Asus P6T).

Step one: Enter the BIOS and go to the "Frequency/Voltage control" menu.
Step two: Change the "CPU Host Frequency" to 180. This should be good for 3.6 GHz.
Step three: Make sure the PCI-E frequency is still at 100MHz.
Step four: Set the CPU Vcore up to around 1.35V
Step five: Go into the "Memory Feature" submenu
Step six: Set the memory frequency as close to 1600MHz as you can. With a 180MHz bclk, this will probably be around 1450MHz or so.
Step seven: Make sure the first 4 memory parameters are (in this order) 9-9-9-24. Also set the last memory parameter to 2T if it isn't set to that already.
Step eight: Go back to the main "Frequency/Voltage control" menu, and make sure the DIMM voltage is set to 1.5V.
Step nine: Leave all other voltages on auto, and then go into the "CPU feature" menu. Disable Turbo Mode.
Step ten: Set the "QPI frequency selection" to the lowest option.


If you do this, then exit out of the BIOS, it should be able to boot up and run at 3.6GHz. It isn't guaranteed, but these are fairly safe, conservative settings, and it shouldn't have a problem running them. After you've verified that it is running fine, then you should try lowering the CPU Vcore a step or two at a time until it is no longer stable. Once you find the cutoff between stable and unstable operation, bump the voltage up a bit from that level (you don't want it right on the edge of stability), and leave it.

Thanks but it didn't work... I enabled the dummy OC thing and apparently it worked this time so I have 3.2GHz right now but I want 3.8 or 4.0 ..... I don't really want to go back into the BIOS, can anyone please tell me what I should do now with the ELEET software to OC it to about those numbers? The core temps are all from 38-41C right now just sitting on the desktop and I think that's good enough to keep going... Preferably just tell me what to crank in ELEET to get it up to ~3.8-4.. Thank you

You can't overclock to 3.8-4.0 in Eleet, you must do it in the bios.

If you're willing to get familiar with the bios I'll help you get there, I've gotten to 4.2 so far with my EVGA x58.
 
It didn't work?

That's really odd. Try using exactly the same settings, but drop the bclk down to 160 That'll only give you 3.2 GHz, but it'll at least be a starting point. Also, check to make sure you have the latest BIOS.

I am just sticking with the 3.2 Dummy OC for now... I got it to about 4.00 GHz but after running Prime95 it got BSOD. Is there a way to get it to a STABLE 3.5 ish using ELEET software?

Alright well BIOS I don't really care... I just want it to be really stable because my room gets really hot during summer and I don't feel safe with the 4 GHz so I would like about 3.5 or so. If you would be so kind as to tell me the exact settings to achieve that I would be very grateful... and it should not BSOD during Prime95 then right? Oh btw how high is too high for VREG? It had about 71 when I was on 4ghz but now at 3.2 it says 60 I think... Thanks man

you can't get someone to tell you "the exact settings" to get a certain overclock. every chip is different. some e5200's will take 1.4volts to get to 4ghz, some e5200's will need 1.7

thats just the way it is. you gotta start low, and start working your way up. get a fairly simple, pretty much guaranteed OC, then slowly increase the bclk by what 3-5mhz at a time? stress test wth orthos, and if it fails, bump up the vcore. stop once you've reached the max temp or vcore you like.

I see... Well this guide I read for 4.0 I copied it and got the same results... I don't really understand what I have to crank though.. Clueless

CJI I will be trying what you said again but for the memory are you sure I should put 9-9-9-24? Cuz I mean my ram says it runs at 8-8-8-21 and thats what I used when I did 4 ghz and I left the 1T also... And last Q about that is the memory freq when I tried ur settings I put it at exactly 1600 was that wrong?
 


It says it runs at 8-8-8-21?

That's odd - the model number is the CL9T, which by Newegg spec is the 9-9-9-24 rated version. As for the memory frequency, you can always try running it slower to see if it is the problem - if you want to troubleshoot, set the memory fairly slow, and then overclock the CPU.

Yeah I have the black ones for sure I'm looking at them right now. Guess I linked wrong or something? I'm following your first post right now, by lowest QPI do you mean lowest on the list or lowest number? I put it on lowest number and am trying it right now.

Hi:

Just logon to EVGA forums and there is OC guide
http://www.evga.com/forums/tm.asp?m=642527


This give a 4.2GHz OC but you can turn down the Bclk to 170 or 160 to get 3.6 or 3.2 GHz.

"I want it now, I want it NOW!"

No one can tell you exactly how to OC your particular board to a certain OC. You have to ease the QPI up a few steps at a time.

Follow Shasemi's OC guide ( not the one the last guy linked) on the EVGA forums. It will only take you a few hours to get to 3.5+. If that's too much time to spend insuring you have done it right then don't bother OCing your machine..

Don't follow JacobF's guide. Use Shansemi's as linked by xKhanx.

It was fairly easy for me to get 3.6ghz. If you have an i7 920 with my batch, getting to 3.6ghz should be similar.
EVGA X58
i7 920 Batch# 3841A453
Gskil Pi DDR3 1600mhz 6gig kit, non black: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231245

First thing you want to do is set all your voltages from auto to manual setting. The default settings are already displayed in the BIOS, just set it to that. Now the easy part : I do not know my VID and Core Temp did not display it, so set my vcore to 1.3125v, which is the default AUTO value.

CPU uncore, use the 16x multi

Memory should be 2:8 1066, leave all your timings on AUTO for now.

Disable CPU features:
Intel Speedstep
Turbo Mode Function
CxE Function
Execute Disable Bit

Slowly increase your Bclk from 133 --> 180 in 10 increments. Make sure you test for stability with Prime95 or another program. With my processor, around 3.5ghz I had to increase the CPU VTT to = +100mv

Not much to it for 3.6ghz, but it gets significantly harder to tune for stability after 3.6ghz.

Hi, Im really new to overclocking and wanted to get my core i7 920 to 3.5.

Could u possibly give me a starting point with voltages and such..i know each is diff per cpu but a bases would be great.

I used the steps listed and it set my cpu to 3.2 with turbo off. Do you think this will be stable? the idle temps are 30 to 34 and the max in an fpu test is 66. can i turn turbo on and have it still run smooth and not damage my cpu?

I made these changes to my bios, restarted, and now have a black screen.

How exactly do I fix this?

CLR_CMOS and start over with a lower BCLK.
