"Core i7 920, Gigabyte X58-UD3R Overclocking Issues"

[caaront]

Hello, I am a new member and was referred here by a trusted online friend.

He has helped me immensely in the past and thought that I would receive the best help possible here.

A quick history is in order, I built the following system myself and have been very happy with it.

It consists of a Gigabyte GA-EX58-UD3R mobo, an i7-920 CPU, 6 GB of OCZ DDR3 RAM, an OCZ 700W PSU, and a GTX 260 GPU.

I hope I added the photo's correctly.

I have been OC'd at 4.2 with multi-threading enabled for the past 6 months with zero issues.

I was getting some stuttering in Flight Simulator X and a friend advised that I change my graphics driver, do some specific tweaks to the FSX cfg file, and return to default clock settings in my BIOS and see if there was any difference.

I did all of the above and saw improvement.

But I did not think that my GTX 260 was a bottleneck so I thought I'd OC to my previous successful OC numbers.

The OC failed, it was getting too hot, so I disabled multi-threading and then the OC was successful with no temps above 75C in the successful OCCT test.

Here are those numbers from my BIOS, NOTE: These are the numbers from the succesfull OC with Multi-threading disabled and that passed the OCCT test.

My OC numbers:

Voltages:

CPU V Core=1.300

QPI/VTT Voltage=1.300

DRAM Voltage=1.640

IOH Core=1.100

CPU PLL=Normal

ICH I/O=Normal

DRAM Termination=Auto

OTHER SETTINGS:

Clock ratio=20x

QPI Link speed= x36

BLCK Freq=200

Performance Enhance= Standard

System Memory Multiplier=8.0

Memory Freq =1600

DRAM Timing Selectable=manual

Profile DDR Voltage=1.5

Profile QPI Voltage=1.2

CHANNEL'S A,B, and C:

CAS Latency Time=8

tRCD=8

tRP=8

tRAS=16 (24)

TURBO BOOST=enabled

CPU Cores enabled-all

CPU Multi-threading=DISABLED 1st test-passed, enabled 2nd test-failed.

C1E Enhanced Halt=disabled

C3/C6/C7 State Support=Disabled

CPU Thermal Monitor=enabled

EIST=disabled

Virtual Tech=disabled

Bi Directional Prochot=disabled

UNCORE Freq=x17 3400MHz

Isochroneous Support=enabled

The OC failed with Multi-threading enabled, the OCCT test resulted in an error in core 2 with a temp spike to 95C.

I am not the most tech savvy person, this was my first build.

I want to learn all I can.

Please do not be harsh with me, I will learn only from constructive criticism and straight-forward advice.

If anyone feels the need to be rude, or criticize solely for the sake of meanness this is not the thread for that, and I am not the type of person who tolerates it.

Any advice, constructive criticism, and help will be most gratefully accepted and appreciated.

Thank you, Aaron

Welcome to XS, Aaron. What is your board version, bios version?

Welcome to XS, Aaron. What is your board version, bios version?

I'll have to check later, although I am back up to 4.0 stable.

I was having problems OC'g after changing a driver to my graphics card, and after posting every number from the MIT section of my BIOS some folks told me to roll back to my previous driver.

One stated that changing to the latest driver for his mouse screwed his stable OC.

I rolled back and am now stable at 4.0 with the highest temp at 100% stress reached being 73C, but mostly hovering between 68C-71C throughout the test.

I have disabled Turbo Boost just to test the temps, I am sure that I can enable it and still pass with flying colors and hit 4.2 GHz.

I have disabled multi-threading, I will test with it enabled later, but I'm sure that I may pass with my current settings if I were to enable it, but might need to come down a little on a couple of voltages.

Key voltages right now:

CPU V core= 1.26875

QPI/VTT= 1.260

DRAM Voltage= 1.640

All the other numbers are the same.

What setting do I enable to allow the CPU to power down when I am not gaming and just surfing the web, etc...?

Thank you.

If I fail after enabling Multi-threading what settings should I adjust?

Thanks, Aaron

Okay, I am back to stable 4.2GHz with the highest temperature reached during testing at 100% load being 77C with the following voltage settings:

CPU V Core= 1.275

QPI/VTT= 1.280

DRAM Voltage= 1.660

Multi-threading-Disabled I'll see about enabling it later on.

EIST-Enabled to allow lower temps and power consumption while not gaming. (I game maybe 5-20 minutes a week)

[caaront]

After enabling EIST and after 30 minutes of just surfing online my CPU was still at 4.2, how long does it take to step down?

And my graphics card is staying a little warmer even with the fan on 50%, will it hurt to run it a little higher at idle?

I run it at 70-75% when using FSX.

Should I enable C1E?

Will it allow the CPU to step down?

[caaront]

I'm very stable and with a few slight changes running even better at 4.2 now in FSX before, the new driver is working great also.

I enabled EIST so when I'm just surfing the web and stuff it throttles down to 2.6 and when I start FSX it goes to 4.2 (checked with real temp and cpuz), it is stable, very good temps, I'm a happy camper.

Thanks for all the help, Aaron
