Core i7 930 overclock problem

[DoDLeZ]

Hi!

My specs:

Intel Core i7 930 D0 с Zalman CNPS10x Performa
Gigabyte GA-X58A-UD3R rev 2.0(last bios version)
Kingston 4GB 1333MHZ CL9(one stick)
Windows 7 SP1 x64

My overclocked cpu does not pass Prime 95 Small FFTs test and crashes with bsod after 10 seconds - 15 minutes
I would like to know that it is possible to fix or change something in my configuration..
I read a lot of topics, but unfortunately answer for my problem isnt found

P.S. Sorry for my bad english

What is the BSOD code? 00000000x124 usually = cpu core voltage...

4.2GHz and 1.38v may not be enough...I also prefer a fixed voltage so I don't have to use basic math.

 

[DoDLeZ]

I had a lot of different BSOD codes))

I thought that for D0 stepping this voltage was enough and ~1.4v is not recomended for 24/7..

 

[EarthDog]

Its been a while since I was on that CPU, but I recall the D0 stepping being better. That said, every CPU is different so just because its a D0 doesnt mean you need X.xx volts to get to said clockspeed.

Also, 4-4.2Ghz is where things topped out there on air really... what temperatures where you hitting before it BSOD?

What is your memory speed at? Can you post pictures of CPUz please with your current settings, specifically the Main, Memory, and SPD tab please?

 

[DoDLeZ]

Core temperatures ~89-95C before bsod

Here is crash dump analys about my most common bsod error

On Wed 14.08.2013 17:26:57 GMT your computer crashed
crash dump file: C:\Windows\Minidump\081413-11325-01.dmp
This was probably caused by the following module: xntkrnl.exe (nt+0x80640)
Bugcheck code: 0xD1 (0x65553F5C, 0x2, 0x8, 0x65553F5C)
Error: DRIVER_IRQL_NOT_LESS_OR_EQUAL
file path: C:\Windows\system32\xntkrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.

A couple things I notice..

1. That is too hot for those CPU's IIRC. You want those less than 90C for stability reasons. Try lowering the clockspeed and voltage to reduce temps.
2. Your memory is WAY overclocked that could also be causing stability. Raise it to 1.55 or 1.6v or lower the speeds of the memory to take that out of the equation or both.

Also, see the guide we have to overclocking these CPUs. With respect, there are some basic principles you are missing that would help you in your endeavor.

Yes, but tj max is 100c and only after that cpu will go in throttling or bsod..or not?

about memory, I raised to 1.64 - no effect, and jedec says that could work with 1600 CL9 on 1.50V

These are my assumptions and guesses, so dont judge me

 

[Nebulous]

@ 95c you're already hitting it's threshold and that will cause instabilities. TJ max is indeed 100c, but that doesn't mean you can run it @ 95c. What will happen is the cpu will eventually overheat and will cause the BSOD's and shut-downs.

As E_D stated that ram is way overclocked. Set your ram divider to 667Mhz and set ram timings manually @ it's rated specs and voltage.

You're trying to overclock both the cpu and the ram at the same time which will not work atm. You need to first stabilize the system @ stock speed, then gradually overclock the cpu ONLY while leaving your ram alone. This will narrow down the issues causing the BSOD's in the first place.

Calm down, no one here is judging you, you're asking for help and that's what E_D has provided to you. You need to check out the link he provided so you can get an understanding on overclocking before you can start. Ramping up voltages and ram speeds is not how it's done.

 

[DoDLeZ]

I can increase coolers speed, so temps may be lower..and I think no one aplication or game can load cpu like prime95, so temps will be much lower

Ram was tested with memtest86 without any errors..

 

[EarthDog]

That is true regarding the temps, but you are failing P95 now, right, and want to pass that? You may need to bring those temps down a bit or raise the voltage to which you have no room temperature wise. You may just want to lower the overclock...

Memtest 86 is a good test, it shouldnt be memory if it passed but... that ram is still WAY overclocked with no voltage changes. Quite surprised its stable honestly.

 

[DoDLeZ]

Okay, will do some tests, and will write here results and observations, thx for help

 

[RJARRRPCGP]

Likely need more Vcore and/or lower core temps.
