That is what memtest86+ said my memory was when I had the timing in the bios set to auto. So I know it crashes at that. I will try a bios update. Thanks

Try them at 5-5-5-18 timings, if still no good I'd try updating the main boards BIOS.

Thanks for the suggestion.

I did what you said and memtest86+ still crashed. Also, when I set the timing to 4-4-4-15 in bios, memtests86+ shows 4-4-4-17. So I set it to 4-4-4-13 in bios and the memtest said it was 4-4-4-15-41. In both instances memtest still crashed. I tired voltage at 2.1, 2.2 and 1.9 and no good results occurred. It is set on 2t timing. I do not know what that means but thought I would mention it. Thank you for your help and I hope to hear more suggestions from you.

I think I see the problem.

Make sure you have the RAM in the correct slots, check your manual.

Now........ with one stick installed ......... go into your main boards BIOS and set the voltage for your RAM to 2.1 volts (mainboards default is 1.8 volts) then go set the rams timings (cas latencies) to 4-4-4-15 reboot, turn off the PC, toss the other stick in, and give it a shot, I bet it boots right up and passes memtest.

Ya it loads windows fine and windows doesn't crash. But I am still troubled by my comp rebooting 5 seconds into the first scan. I am using memtest86+ 2.11. It runs after post and before windows.

More detailed spec:

AMD Phenom 9950BE

OCZ Reaper HPC Edition 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800

MSI K9a2 Platinum

Sapphire Ati 4870

850 psu

Hope this can help. Thanks for your responses.

In addition to GmsCool:

What kind of memetest do you run? "Memtest 86" that runs after computer POST and before computer boots in WINDOWS can't crash anything.

So it boots to windows just fine?

Try a different Version of Memtest (that one might not like your hardware)

And list your hardware.

I've tried using two chips that are exactly the same. They came in their own set together and they still reboot the comp during memtest. Also for whitelotus's reply, the comp is rebooting during the memtest. Not during normal booting and running of windows. I am starting to this it may be a motherboard issue.

There could be many reasons that may cause this. I did a search on google and found this info. You may read it and see if it helps.

ask-leo:

So here's what I would do, when faced with a randomly rebooting computer:

Yes, I would consider upgrading to Windows XP, if the machine was capable of it.

Make sure that anti-virus and anti-spyware utilities are running and up-to-date.

Make sure that the operating system and all device drivers are as up-to-date as possible.

Run a memory diagnostic such as Memtest86 or Windows memory Diagnostic.

Run a hard disk diagnostic such as SpinRite.

Run a motherboard temperature monitoring tool such as Motherboard Monitor - it's a free tool that will report your CPU's temperature among other things, and will let you see if the machine is overheating for some reason.

At this point I've done pretty much everything I can that doesn't involve opening the computer. If the problem isn't evident or resolved, we need to get a little more serious. This might also be the time for some to simply take their computer in to a technician for diagnosis.

Next, I'd open up the computer and:

Carefully vacuum all the dust out of the machine.

Make sure that the fans which are accessible are running properly. If not, I replace them. If the machine doesn't crash as quickly with the cover off, that's often a sign of overheating.

Remove as many optional hardware components as possible that would still allow the machine to run. If the problem disappeared, I would re-install components until it reappeared, and then remove other components to make sure that the problem was associated with only a specific component.

Re-seat all remaining and accessible connectors and expansion cards - sometimes problems are as simple as a loose connection.

Then it might be RAM conflict Did you use different brands or the RAM with different CAS L?

Whenever I put in more than one chip to scan with memtest my systems crashes and reboots after scanning for around 5 seconds. I have individually tested the chips and they have not reported any errors. Anyone know whats up?
