Windows 7: BSOD Win7 Pro 64bit - ntoskrnl.exe??

25 Nov 2010   #21

Windows 7 Pro 64bit

Mobo: Gigabyte 880GA-UD3GH
RAM: 2x OCZ 2GB 1333MHz Platinum AMD Ediotion (PN OCZ3P133LVAM4GK).

Of course I started post on OCZ official forum. By now I'm waiting for replay, maybe someday I got one...

I checked out your motherboard manual.

Make sure you have the RAM in the Blue slots, since you are only using 2 sticks.

In manual I couldn't find anything about in which slots I should plug sticks but to plug them into one of channels (both blue or with slots). For long time they were running in blue slots, and BSOD appears. Now I'm testing them in white slots. Tests in first white slot passed.

Now I got strange issue. When I tested single memory stick in first white slot memtest86+ showed:
RAM: 666MHz (DDR1333).
but now I'm testing second white slot and got only:
RAM: 200 MHz (DDR400).
Can you say why??

I'm using UNGAGED mode, as it is mentioned in OCZ forum, so 64bit bandwith (not DUAL CHANNEL?).

this is my therad on this forum.

Hi pskierczy, with some information on your system we can adjust some settings.
D/L CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.

For posting the information , enter 'Snipping tool' in the Start button > Search box, hit enter. Select the area you want to post and save to a convenient place.

Have you been checking your temperatures?

Speed Fan or Core Temp , run one of these and check the CPU temps when at idle, under load and/or testing.
Let us know the minimum and maximum temps you get.

Go to your BIOS and tell us what the RAM and North Bridge (NB) voltages are.

First, sorry for posting just part of info you required.

Now I'm at work, but I think I got some interesting info:
All day I was testing my RAM in second slot (as mentioned above) and for first stick got no errors (12 passes) but for second I got errors on first pass (test #7) MB about 1000-1100. So I decided to test it other slot just to make sure it is damaged. So I pluged it in first blue slot and run some tests. After about 5 passes and no errors I decided to run just test #7 because just this one caused some errors. What is more I limit test space to 1000M+... and after 20 passes got no errors... I'm really confused... By now I pluged RAM sticks in one blue and one white slot (both first) ans run allnight test. We'll see what it show.

I've installed all programs that Dave mentioned. And what can I say:
temp (idle): below 30C and that is on Core #0 and only this temp i can get from CPU.
other temps: sligtly above 30-35C, so rather low.

If we're talking about cooling, I got one fan on CPU and that is OEM. One in front of case - preinstalled.
PSU - 135mm fan(as I remember), one on side (70mm) Fander ROXO, and one on back, Fander Selekta 92mm, so I think cooling is OK. They're running at about 1800-2100 rpm, so at max speed or maybe 90% of max speed.
What is more when CPU is idle it sets speed to 800MHz (multipler goes from 16 to 4).

Voltages (and other BIOS stuff) are all set according to OCZ instructions, so:
Set Memory Clock to { Manual } and { x6.66 }
Set System Voltage Control to { Manual }
Set DRAM Voltage Control to { 1.65 volts }
Set CPU NB VID Control from { 1.2 to 1.35 volts } mine is 1.35V

Set DCTs Mode to { Unganged }
Set DDR3 Timing Items to { Manual }
Set DRAM Timings to 7-7-7-20 (CL-TRCD-TRP-TRAS)
Set 1T/2T Command Timing to { 2T }
PCIe Spread Spectrum to { Disabled }
One more thing...
I was building this system myself and it was my first build from zero (ealier I just replace just some parts) so I started to thinking what could I pluged/did wrong or what are common mistakes in assembling new system. One of my friends told me that maybe thermal paste layer between CPU and CPU cooler was to small or smth. But mine was already put on radiator and require just to mount it on PSU (as it was OEM)

Sorry for so long post.
Tomorow I'll paste rest of info Dave asked for. How long stress test should I do to make it reliable? (Prime95 or OCCT Perestroika)

Mine allnight RAM test (20 passes for whole 4GB of RAM) showed no errors...
Since new instalation of OS I also got no BSOD(maybe because I ran a lot of tests with memtest and rarely use Windows.

Now I'm running Prime95 stress test. After about 30-40min, temps got stable. My readings are here,but I do not know what are Temp1 to 3...

If you're not getting errors or BSoDs anymore you should be good.

Let us know if you get any more BSoDs or memtest errors.

If you have any problems you can relax the timings a little.

Try 8-8-8-19 and leave the 'Command Rate' at 2T.

Hi again

Again I got BSODs while windows logging in. So I decided to check it by memtest86+ and got 190k+ errors on tests 5,6,7,8. All adresses above 2048 (second RAM stick, whichever it is).
It is impossible that BSODs are caused by software errors. Now the main task is to know if this is really RAM error.

I swapped RAM sticks (but use this same slots) and got no errors. Also windows started normally.
IMHO this must be mobo or CPU malfunction. Correct me if I'm wrong, but swapping RAMs I change system config. And then got no errors. So surley not RAM is fault.

I'm doubting than any software can caouse such as errors.

Now please replay. Is there any tests that can determine whether mobo or CPU is faulty?

I got another BSOD. But what I found it maybe incoplatible RAM. I do not know why My ram, but not AMD Ed. is compatible, but mine may no be. This I got from gigabyte tech support. But they do not seem to be helpful (they just "do they job", nothing more).

Would you mind taking a look at this reports??
Attachment 119087

What more I found is that OCZ tech suport know such as issue. But do not know how to solve. One more time incompatibility I guess.
