Games crash -> bad memory?

[mr.gearhead]

Hi there!

I bought a new 6800GT recently and my problems began. During games, my computer crashes. but in a strange way. I can hear some strange sound continously and my monitor displayes strange colors in a strange resolution. Its definitely no temp-prob and the videocard is also ok (tested in other systems). Even buying a new Powersupply didn't solve the problem. Working on XP-desktop for hours is absolutely no problem. But the games.... Fear Demo, Starship Troopers Demo, Halo, fun for about 4 minutes but then my monitor seems to have a party on lsd ;-). Games like Fable or Dundeon Siege 2 Demo work fine funny enough.

First step was testing only one of my rammodules. it worked! like a slideshow indeed, but it worked. playing with the other module installed caused the game to crash and return to the desktop. Not like I described above so I had to reboot, only to the desktop.

 

Today i tested my rammodules. Did I find the wrongdoers?

 

Here the results after testing each module for about 1 hour:

first one gave me 4119 failures, the other one 196.

 

My system:

Asus P4C800 Deluxe latest Bios

Pentium4 3,0

2X CMX512-3200C2; Version2.2; LotNumber 0320021

running at 2,85V; 2-3-3-5

 

Please excuse my bad english, I'm from old europe ;-), but thanks for any help

 

greetz,

p.s.: I also posted in the Customer Care's Forum 2 days ago. Maybe someone can delete that thread.

Was the system running properly before you changed the Video Card? And have you ran http://www.memtest.org on the modules one at a time? Please note that you will need to disable legcay USB when running any memory test with this MB.

Before I changed the Videocard, everything worked fine and rockstable. But with my 6800GT I play with higher Details in higher resolutions which stress my ram more than before. Therefore my first thought that the Powersupply had too less Ampère.

Yes, I tested each module at one with memtest running from a bootable disc. Same slot, same configuration.

 

I'm not sure whether I disabled legacy USB. But I'll have a look and test again if not.

 

Thanx for your help so far.

back again. tested the module which crashes games to dektop in singlemode for about half an hour (described in my first post above). USB function completely deactivated.

 

..3982 errors....

 

:(:

[mr.gearhead]

here some new results:

 

1) Ram A (the one which gave me the most errors) in another system (AMD64)

2-3-3-6 2,8V -> 230 Errors

2,5-3-3-8 (SPD) 2,8V -> 38 Errors

each test for about half an hour

 

2)2 Kingston modules in my system 2,6V SPD; Fear Demo -> running properly

 

3)Both Corsair Rams in my system with 2,6V SPD; Fear Demo -> crash to funny colors, strange resolultion colors and sound after a few minutes.

The USB controller needs to be enabled, but legacy USB will have to be disabled. If you just disable the controller that will not solve that issue. What you have posted would suggest a power problem, can you test them in another system or test with your old video card installed? However, I have no problem replacing your modules. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!

Ok. USB legacy deactivated, USB controller activated.

2-3-3-6; 2,85 -> Ram a: 1753 errors, Ram B 128 errors.

 

I would rule out a power problem. I use an Elan Vital 400W (2x15A), only one HD, cd-burner, dvd-burner, Audigy ZS, 2x120mm fans, 6800GT, P4 3,0. nothing else. with other Rams installed, all games work fine.

Testing the rams in another system, memtest produces errors also

 

Thanks for offering the replacement and bearing with me :):

Let's get them both replaced. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!
