BSOD Problems - Vista x64 and ntoskrnl.exe

Hi there, I'm wondering if someone could help or some advice.

Under a month ago, I installed a new hard drive a extra 4 gig of ram and Vista Ultimate x64, then every other day I would get a BSOD (and still do) and the likely cause was\is by the following module: ntoskrnl.exe, with errors ranging from

PAGE_FAULT_IN_NONPAGED_AREA (3 times)
IRQL_NOT_LESS_OR_EQUAL (4 times)
SYSTEM_SERVICE_EXCEPTION (4 times)
DRIVER_POWER_STATE_FAILURE (Once so far)
BAD_POOL_HEADER (Once so far)

I had other BSOD with other errors caused by the following modules: ntfs.sys, ecache.sys and aswtdi.sys but the majority of the BSOD are caused by ntoskrnl.exe.

Now in the past week I have ran an extensive memory test using memtest86+ v4.00 testing 11 different combinations like slots 1 and 2, slots 3 and 4,, slots 1, 2 and 3, slots 1, 2 and 4 and so on, and all have passed, I've ran some twice and have passed twice,

I have tested the Hard Drive that C: is located on using both CHKDSK /R and Western Digital's Data Lifeguard Diagnostic for Windows (since the drive is a Western Digital) and it has passed with out any errors being detected but am still getting the BSOD with it likely caused by the following module: ntoskrnl.exe, (the error is never the same).

At first I thought it might be a problem with a program called AutoGK (v2.55), as I suddenly would get a BSOD 10 minutes after the program had started and was in use, so uninstalled it and installed an older version as I didn't have problems with it when I had Vista Ultimate x64 previously, but then would get a BSOD when I was viewing web pages from IE and AutoGK wasn't running, so now I'm at a loss.

I'm now wondering if it’s just a simple case of a Windows or Software problem or that even though Vista Ultimate x64 was installed it might not have installed some system file correctly and that formatting the hard drive then re-installing windows will sort this out as I've never experienced anything like this when Ultimate x64 was installed before (but did experience my PC randomly freezing when I logged in to Windows, but was fine once I rebooted).

Since both memory and hard drive have reported no errors, the voltage for the memory is at the correct voltage of 1.8v, the memory I have is on my motherboard QVL and also the motherboard is on my memory's QVL, all sound and video card drivers are up-to-date and I don't over clock my PC (this is why I'm pointing to a Windows\Software problem).

Another things is I'm also wondering if my Bios settings are also 'to blame', as I need to change the setting from IDE to ACHI, as I have 4 sata drives in the 1st 4 Sata ports and a Sata Dvd Drive in the 5th Sata port, and in order to get my DVD drive to work and to be detected I can't select IDE, as that only recognises the 1st 4 Sata ports on my Motherboard.

it cant be anything but your ram every dump file is uniqely differant it HAS to be hardware , up it by .1 of a volt in yuor bios to 1.9 see if it helps

adding an extra 2 modules nearly always causes voltage issues , if that doesnt work slackening the timings or underclocking the ram a little could help

memtest is good as long as your running it in "dos" and a s long as you run it for at least 8 hours and show no errors , even then it can "pass" memory as stable and the os will still throw a wobbler

The voltage is now up to 1.978v in the Bios and will give that a try and hopefully in the next few days i'll run memtest 86+ for the 8 hours and see what happens, if I'm still having problems, I'm going to try your idea of undercloking from 667 to 533.

see how it goes although i do think that voltage will be fine kingston only warrentys that ram up to 1.9v so be carefull

if you have to undeclock it (you shouldnt) see what options the dividers offer 533 is a little slow

i forgot to ask is that the voltage you set in bios? if so what voltage are you getting in windows?

if your not sure download HWMonitor run it and look at the DDR voltage

CPUID

1.978v is what I set it in the Bios and from CPU-Z (HWMonitor wont display the ram voltage), its says solts 1 to 4 are 1.8V (on JEDEC 1 to 3)

Got another BSOD about 10 minutes ago while playing C.O D 4 Modern Warfare but it was fine when playing C.O.D Modern Warfare 2,

So..........going to remove the newer RAM that was replaced 2 weeks ago and going to see if that makes any difference and reset the default voltage settings, if it does, then I know to contact Kingston, if not going to run Memtest 86+ v4.00 then contact Kingston.

Ok, have done some more testing of the memory today, and have tested each of the ram sticks and all have passed at least 3 times, going to test them all together overnight and see if theres any errors.

But just wondering, on the motherboards QVL list, its got for AM2 supported CPU, that the motherboard supports

One module inserted in any slot as Single-channel memory configuration.

One pair of modules inserted into eithor the blue slots or the black slots as one pair of Dual-channel memory configuration.

But does not support (as I thought it did) 4 modules inserted into both the blue and black slots as two pairs of Dual-channel memory configuration <----could this be whats causing the BSOD?

Ran memtest+ 86 v4.00 for 8 and half hours and found no errors.

Got an emial back from Asus (motherboard manufactures) and got this reply

The memory sepc of this motherboard is, 4 x DIMM, Max. 8 GB, DDR2 1066/800/667 ECC,Non-ECC,Un-buffered Memory. You can install 4 sticks ram, only the 1066Mhz memory has limitation: only one in per channel. We recommend you use the same spec of the ram. Maybe adjust the memory voltage and the CL according to the memory manual is better.

So I am thinking that I can run 4xKVR667D2N5/2GB


Still getting the BSOD even though the voltage back to auto and have set the memory timings manually to 667, going to see if reinstalling windows or windows 7 on a separate drive will fix this.
