Overclocking i7 920 + x58 UD4P

[bob saget]

Guess I am ready to dive into overclocking this guy. Current temps at stock are about 30C at idle and 65C at load with prime.
I am looking to get my memory snappy and a 3.6ish overclock with the lowest temps possible.
This is the memory I have: Corsair XMS3 Dominator TR3X6G1600C8D

http://www.corsair.com/_datasheets/TR3X6G1600C8D.pdf

I'd prefer just bios settings that i can go along and fill in. I am not much of a tinkerer.
I'd also appreciate some advice on what to do if computer does not boot.
Currently I have not changed anything in bios, other than the flash.
I am not sure what to think of hyperthreading.

Thanks for your help as always.

If you will search this forum with "UD4P Overclock" you will find enough information to keep you busy for quite a while. Once you do that you can come back with specific questions and you will find a wealth of help.

Thanks.
I was hoping however for just a bios template for 3.6, preferably from lsdmeasap because he obviously has a wealth of experience with this board. Like I said, I'd rather not start experimenting on my own from zero. Once I get to my desired range, maybe I could do a bit by myself.

Re: Overclocking i7 920 + x58 UD4P

Well you will still need to tinker a bit, as you will need to find your own optimum CPU Vcore, QPI/Vtt, and IOH Voltages, but that only leaves you with three or so settings to tinker with instead of 30-40

0X00000050 << Incorrect Memory Timing/Freq or Uncore Multi
0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
0X00000101 << Not enough Vcore Voltage

3.6 is a iffy spot to pick, you can use 190x19 to keep ram at 1520, or use 170x21 for ram at 1700, all up to you

OK
So just to double check, if i choose to go 190x19, i need to set
Clock Ratio - 19x
BCLK - 190
I am a little confused about the Uncore, QPI, and SPD.
Basically, what would be the difference, 8x or 10x for the SPD.
Also, for the ICH I/O, what does that mean see below?

Also, if say I fail to boot, i need to press clear cmos button?

Thanks for the settings BTW.

Re: Overclocking i7 920 + x58 UD4P

Yeap to that, sorry I wasn't sure of the better way to write that out in the settings.

SPD is you memory multiplier, it will be x whatever you use for Bclk. So 190 Bclk x 8 will be 1520Mhz ram speed.

Uncore would need to be, if using 8 SPD, x16-18

ICH I/O Comment, only meant the same applies as to what I wrote for ICH Core

Yes, if you fail to boot and trying several times does not help then you may need to either unplug the PSU for a second, or clear CMOS. Removing one stick of ram can help sometimes as well as this will update the DMI pool, but that isn't always a option for users to to. Clear CMOS button works fine on these boards, with the PSU Plugged in as well, just press and hold it with the system off for 20-30 second and it will clear the CMOS

Anytime, that's why I am here!

Good luck pushing things!

Re: Overclocking i7 920 + x58 UD4P

I am really confused with an issue I have.
I followed the above settings for 4.0, i am getting 3990.XX, dont know if it matters.
Booted. Idling at about 40ish. The second i load prime, my core voltage shoots up to 1.6. I am seeing the core voltage through cpu-z.
And even in bios at the setting one higher than 1.25, its showing a core voltage of 1.248.

[Lsdmeasap]

Re: Overclocking i7 920 + x58 UD4P

Just replied to your PM

Na, what you mention about 3.xxx is normal, raise the Bclk 1 if you want it to be above 3.xx

What CPU-z are you using? And what Vcore in the BIOS?

[bob saget]

Re: Overclocking i7 920 + x58 UD4P

cpu-z version 1.52.

[Lsdmeasap]

Re: Overclocking i7 920 + x58 UD4P

Please use 1.52.1

What Vcore set in the BIOS? BIOS F9c right?

[bob saget]

Re: Overclocking i7 920 + x58 UD4P

Bios is F9c.

[Lsdmeasap]

Re: Overclocking i7 920 + x58 UD4P

Hmm, PM Sent. Very odd

[bob saget]

Re: Overclocking i7 920 + x58 UD4P

With LinX and Everest, CPU Core goes up and down, 1.26 to 1.66, back ad forth.

[Lsdmeasap]

Re: Overclocking i7 920 + x58 UD4P

Why did you post that pic? It just shows 1.26V?

I think via PM you noted the cause, BIOS F8 right?
