Hi guys I have a problem where if my system gets stressed, it crashes and restarts. It's a new system I put together myself, and its driving me crazy, so I would appreciate any help.

System:
Motherboard: Asus Extreme Striker
Ram: 3 GB (3x1GB) Corsair XMS2 – 6400 (800)
GPU: 2x Nvidia GeForce 8800 GTX running in SLi
Sound Card: Creative Sound Blaster X-Fi Xtreme Audio
Hard Drive: 2x Western Digital Raptor (10,000 RPM) 150 GB
CPU: Intel Core 2 Extreme QX6800
OS: Windows Vista Ultimate 32bit
Power Supply: Enermax Galaxy 850W
Chasis: Thermaltake Kandalf LCS

First let me say I’ve updated every component with the most recent drivers, and updated the bios to the newest version (1102)

The system first crashed while I was running Battlefield 2. I tried it again and the same thing happened. I figured it might be a problem with a game. But then I tested the system and ran two movies at the same time. After about a half hour the system crashed again. I ran a system stability test using the Stability Test on the Nvidia Control Panel, and the system crashed after almost a half hour.

I only ever got a Blue Screen of Death once, and the error was
Bad_pool_caller
0x000002, 0x00000007, 0x0000113d, 0x886e0620, 0x886e0628

I figured it might be the audio card, so I disabled the card from Device Manager. Unfortunately the system crashed again. The system only crashes when running something intensive, like movies, or a game, or the Nvidia stability test. The BSOD never repeated, the system just crashes and automatically reboots.

Event Viewer in the control panel lists dozens and dozens of the following Event ID 6 error:
IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 24, function 0. Please contact your system vendor for technical assistance.

The PCI Slot numbers in the event error change, but I read an article on the microsoft support site that said this was normal with vista, and could be safely ignored, which means I don't know if its relevant.

I’ve got a liquid cooling system on the CPU.

Unfortunately I can’t see what the temperature is for the graphics cards, because the Nvidia Control Panel doesn’t show their temperatures, even though I’ve installed ntune. I even downloaded sensors view, and it won't show my GPU temperatures either!

The whole system's only a few days old. Recently I tried to install a program, got the BSOD and the below message. I don't know if its related.
pfn_lilst_corrupt

0x0000004e (0x00000099,0x00072f1d,0x00000002,0x00048f1c)

it really sucks

I don't know whats wrong, and I'd appreciate any advice, as its driving me up the wall. Thanks!

please see attached files from cpu-z and pcprobe, they might help you see whats up!

finally found out how to check the GPU's temperatures. They are at 78degres Celcius at idle... could this be the problem?

78 is much idle maybe it cant handle when load.. both cards at 78? how many fans u have at ur gtx's? i would say the normal is 60-65 idle with a gtx

Hot.. but I doubt it.. Nvidia driver should warn you before temp goes critical and shutting down PC and on the restart it should be mencioned as well.... try gaming under XP.. should correct the problem. If not, well maybe even some of the great Enermax powersupplies are faulty?

Before that try testing your RAM stick by stick or download Sandra/PCmark and try stressing different components to see witch stress crashes you PC sooner.

I don't know what else to add really, system specs are awesome and if I got that problem with your setup I would start testing RAM stick buy stick under WinXP before suspecting anything else.

thanks for the advice guys.

I don't think its the temperature anymore... i ran two movies at the same time to crash the system.. when it crashed CPU was at 34 degrees celcius, and the video cards were at 79 degrees celcius, so hardly any different than idle, and the system was stable on idle.

Honostly.. I would be VERY surpriced if it didn't turn out to be one of your memory sticks..

This is not an hardware error. The bad_pool_caller error on BSOD indicate an driver error. That stop sign is the stop code and he points you to a bad driver. Under the 0x0000050***it shood be a name of the driver if some concrete one, if not then its a blank line. so you need to reinstall that driver, if you can find out what that is.

OR it could be his RAM and drivers fail because of it. I've had a faulty stick once and received MASSIVE amount of errors and his problem seems very similar to mine. It could be anything but I will press on checking his Corsair Stick By Stick before anything else !

In any case.. if you have the Corsair XMS2 that runs at CL4 and not the CL5 your memory voltage is lower then it's very minimum (1.9 instead of 2.0 if you read the manual) What RAM do you have exacly?

BTW: I just found another XMS2 that needs 2.1V of juice:

XMS2

thanks alot for the advice gys, its much appreciated!

I decided to use the nvidia control panel to perform a stability test on individual components...

I tested the RAM first... after 20 minutes i got the BSOD

So it must be some problem with the ram. I'm worried however because shortly before that I got a message from ASUS PC Probe II that said:

there are some warnings:
NB Core Voltage

My NB Core Voltage was 1.23v at the time

Does anyone know what that message might mean?

I've started testing individual ram sticks, i'll stress test each stick for an hour. I really really really hope I find one stick that messes the system. I'm worried it might be a problem with my power supply 8O


EDIT: just saw your second post xela, thanks btw My ram is listed as Corsair CM2x1024-6400

More info from back on one of my ram sticks:
5-5-5-12
800MHz
1024MB
XMS2-6400

That is possible to, im not saying he shouldn't check his RAM but for bad RAM usually comes some of this BSOD: UNEXPECTED_KERNEL_MODE_TRAP-more common for overclockers, PFN_LIST_CORRUPT-this is in 99% bad RAM or PAGE_FAULT_IN_NONPAGED_AREA-this is also usually bad RAM and your statement "OR it could be his RAM and drivers fail because of it" would most probably be this message from BSOD.

I can't see anything wrong with NB voltage beeing 1.23v.. I would think that it is your mobo's default. NB = North Bridge (a chip that handles communications between the CPU, RAM, AGP or PCI Express, and the southbridge.)

Before you start testing any of your sticks make sure you set RAM voltage is set to 2.1 in your bios. It won't burn your ram even if it works on lower voltage and will make sure that it gets enought juice if you have a decent XMS2 !!!

xela i think there might be something to what you're saying.

i think shows my ram, and its says it was tested at 1.9v I don't know if that means thats the voltage I should set it to. PC Probe has my memory at 1.87v

About your edit, I found this:

http://www.zipzoomfly.com/jsp/Prod [...] de=85025-2

Retail
1024 Megabytes of memory in a 240-pin DDR2 DIMM
Implemented using 64M x 8 DDR2 SDRAMs
100% tested at 800MHz in high performance DDR2 motherboards
Legendary Corsair reliability and service
Test Specs
Each module is tested in an Intel-based motherboard at 800MHz
Tested at at the latencies of (5-5-5-12) at 2.1V
SPD programmed at standard latencies of 5-5-5-12

Please note the part where it sais tested 2.1 Volt for your sticks
EDIT: It will NOT heart to try 2.1 even if they say 1.9 in the manual
10$ that we have located your problem
