Damn this thing, trying to OC to atleast 3.2 ghz and iam only getting up to 3.1 ghz(Actual goal is 3.3-3.5)

setup...

intel core 2 e6600 (@ 3.1 ghz under full load temp 49c)
intel 975XBX
Corsair 6400 C4 2 gig 4,4,4,12 800mhz
600w PSU Enermax


Anyways I tried tons of settings in the BIOs.
(Combination)
Memory - 5,5,5,15 ..4,4,4,12/15..667 mhz then 533 mhz @ 2.1 volts. notta
CPU - Tried 1.5 volts nothing, 1.6 volts nothing and i didn't go higher.


Very lost at this point. Usually i do good when it comes to OCing.
 
5-5-5-15 @ 533, 2.1v doesn't get it for you?

Disabled C1 and enhanced halt steppings?

Disabled spread spectrum and everything else you dont need?
 
Try 2.2 v on the ram if you can. I remember I had the same issue, I kept ignoring ram voltage and as it turned out 2.1 wasn't enough. 2.2 won't melt your ram anyway.
 
Hehe, ok well here are some things to try

If 5-5-5-15 RAM timings @ DDR2-533 speeds dont let you post,

Have you tried locking the PCIe bus at 101 or 110mhz instead of the stock 100?

Make sure "Spread Spectrum" is disabled
 
Far as i know(which isn't much) its set at 100 mhz at default. I'll try and fiddle with it..brb...

There's not to many options on this intel board...
 
Couldn't find CPU spread spectrum anywheres. Also tried moving the PCIe mhz around, 101.23 and 109.70. Still stuck at 3.0 ghz stable using Orthos and the folding program. I checked out that diagram and found five 975XBX boards that OCed fairly well. I just don't understand why i can't achieve 3.4ghz.
 
Are you using a "stock" 975XBX? Or have you modded the board to show the rest of the option needed for overclocking?

A standard 975XBX can only overclock up to 30% and it doesn't allow you to change the CPU Voltage which is what you might be needing right now.

If you want more, be prepare to do a very simple and effective mod to the board!

I'll try and link it soon!
 
Wow thanks Orion, never thought about that. Here's a question, why bother adding the voltage and 50%(should be around 3.5 - 3.7ghz) burn-in OC when it can't do it? Right now iam at 25% burn-in ...meaning iam OCed to 3.0 ghz; 9x335.5.

And please if you have a link id love to have it...

again thanks.

Edit: Oh and also, does MCH mean the CPU voltage or something else? It shows 1.58v - 1.89v. And then theres the FSB voltage override, 1.3-1.4v.
 
From your link it shows how to mod to increase the memory voltage. Orion also meantioned after 30% it can't OC anymore. Just wondering if i also need to mod something else or this "taking a pencil to it" idea actually works :confused:
 
Sorry. I forgot your link:

Look at picture # 3. All you need is a conductive ink pen (radioshack) to trace a small connection between the 2 points (very easy to do, I did it on my previous 975XBX and it worked)

After you do that, you will have access to a 50% burn in mode and a few extra options.
The most important being Vcore Voltage which is what's probably holding you back!

Also keep in mind, that 975XBX boards use 2 different "clock generator"

http://www.xtremesystems.org/forums/showthread.php?t=108863&highlight=clockgen

1 of them allows using anything higher than 30%
The other one will not. Even though you might be selectin 40% in the Bios, the board will now go beyond 30%. My board unfortunately had this problem.

Also, the is a program called "systool" which allows you to overclock higher IN WINDOWS. The downside is that you have to to this manually everytime you restart the PC.

MCH = Memory Controller Hub. This is the voltage needed for the boards to work at high FSB and / or high memory overclocks.

Same goes for the FSB Voltage. You just have to try upping those together with the CPU Voltage (Vcore). Setting any value too high might lock your board so go easy, small increments.

Also, The maximum value for the CPU Voltage shouldn't be higher than 1.55 which for some is already too high.
