Help Overclocking i7 920 D0 with EX58-UD5
« on: December 31, 2009, 02:44:58 am »
Here is a list of my gear:

Antec P183 Case

Gigabyte EX58-UD5 Intel X58 Motherboard

Intel Core i7 920 D0 Stepping (SLBEJ) 2.66Ghz

Corsair H50-1

Corsair XMS3 6GB PC3-12800C9 DDR3

Sapphire 5770 1GB New Edition

Corsair 1000W Power Supply

4 x 1.5 TB seagate 7200 RPM 32mb cache for storage

1 x Curcial M225 SSD (64gb for installing Windows 7 Home Premium 64bit)

Please can someone assist me in guiding how to overclock my system to 4GHZ. I mean I have looked around and found these settings is this a good option or does someone have a better settings? please consider all my equipment as stated above.. Here are the settings which I think may be good for 4 GHZ overclocking.. I want to get the best out of my RAM and CPU any advice and help is welcome. or shall I just use the Overclockers profile which they use for this setup?

SETTINGS SEEN ON ANOTHER FORUM:
Ai Overclock Tuner - Manual
CPU Ratio Setting - Auto
Intel (R) SpeedStep (TM) Tech - Enabled
Intel (R) Turbo Mode Tech - Enabled
BCLK Frequency - 190
PCIE Fequency - 100
DRAM Frequency - DDR3 - 1523MHz - If you use memory that is slower than 1600MHz, you can use the next lowest setting here, however, if you use faster memory, such as 1866MHz or even 2000MHz, please stick with this setting for now.

DRAM CAS# Latency - 8 DRAM Clock
DRAM RAS# to CAS# Delay - 8 DRAM Clock
DRAM RAS# PRE Time - 8 DRAM Clock
DRAM RAS# ACT Time - 24 DRAM Clock

CPU Voltage 1.25000v - This is our maximum Vcore
CPU PLL Voltage - Auto
QPI/DRAM Core Voltage - 1.3v - We need to up this to 1.3v to maintain stability, or at least I did on my CPU, your mileage may vary and you may need slightly more or slightly less.
IOH Voltage - Auto
IOH PCIE Voltage - Auto
ICH Voltage - Auto
ICH Voltage - Auto

DRAM Bus Voltage - 1.66v
DRAM DATA REF Voltage on CHA - Auto

Hi,
There are some good guides for overclocking in this section, ;D
But bear in mind that all systems are not equal, even though they are the same components, 8)
What works on one setup does not work on another,
Your only option is to change settings and benchmark to find the sweet spot,
one of the forum overclockers has hit 4.5 and going for 4.6/7 ish,
Cheers

the above guide does not explain much.. please can some one give me a step by step guide possibly with bios screen shots if possible :)

Hi,
Sorry it's all DIY what works for one setup won't for another,
You got some base lines here above, all the rest comes from your working, benching, adjusting, benching again to find out what you can get stable,
Information you want, Start here, http://forums.tweaktown.com/f69/
happy new year

I have to disagree slightly with the above.

Overclocking should be done manually, gradually and with understanding of each of the settings. This will get the best results. However overclocking is rather simpler than it used to be, and you can get reasonable results with remarkably little knowledge.

As an example, set the following
qpi to x36
unclock to x16
ram muli to x8, timings to c9
vdimm to 1.66V
qpi voltage to 1.3V
vcore to 1.3V
turbo off, load line calibration off

This will leave you with ram running below spec, processor at 2.66ghz. Run ibt/prime95 for ages to check it's stable, I'd be astonished if it wasn't. Increase bsck to 150, retest. Then increase bsck 5 at a time, testing each step. When the tests fail, go back to the last stable bsck and you're done. What frequency you hit from this is a bit hard to guess, should be 3.8-4.0 ish.

I'll reiterate though, researching this and spending time on it will achieve significantly better results. Not least that a lot of settings are system specific, cpu pll, pci clock drive, cpu clock drive, qpi pll all have to be set on an individual basis. In my case 1.7, 800mv, 800mv, 1.14, but for you these values will not work better than defaults.
