BSOD's cause by non-IBM memory?

I hear this is a widespread issue with the company's T42. BSOD's (blue screens).
Crucial memory installed. Should we (and I) go with IBM memory?
Anyone else on this forum experience this problem?

I can't speak for your t42, but i installed some samsung chipset 1gb pc4200 into this t43 and haven't had problems.

I think it would be safe to say that I have more experience with T4X series Thinkpads than you and I have never heard anything of the sort.

Crucial (Micron) RAM has been one of the preferred brands for Thinkpads over the years. It is one of the brands IBM will label as their "own" and you're likely to find in your new machine as it ships from the factory.

my friend is using 1slot of Kingston 1GB ram in his T42 as well.
Nothing is going wrong with it.
working well,

What leads you to think that the BSODs all over the company are related to the RAM that's installed? It could be something the company is installing on all their T42 images.

Sounds like what's called "shotgun troubleshooting" to me.

Here you will a few people with the same problem.
In fact someone makes the point that this forum does not want to hear about this problem. I hope this is not true and any person should be able to come here and solve whatever problem they have.

In a quick read of the above URL I didn't note anyone saying that their problems stemmed from using non-IBM memory, your original subject and contention.

Yes, the ATI video chip problem in the T4X series machines is a known problem and has been discussed to death here, so no, it's not true that we "don't want to hear it".

My T40 (2373-8CU) is on its second motherboard for precisely this problem.

I'll repeat myself and tell you that if you were to order "IBM" memory to replace the Crucial memory in your affected systems, the memory you receive from IBM will quite likely be a stick of Micron (Crucial) memory with an IBM label on it.

Not overclocking are you?

If it's stock crucial RAM, it's the *exact* same thing IBM will sell you for more than 2X the price. It's literally just putting an IBM sticker over it. That's all.

May want to compile and test with memtest. If that passes, then I'd say the RAM is good and start looking elsewhere. If it fails, likely just a bad stick.

Getting a little cranky here,...?

Hehe, my firm's IT guys just upped my T41 to 2 GB memory, dunno what brand, and a few weeks later, my HDD starting eating itself (bad sectors multiplying like rabbits). Maybe there's a connection!

Or maybe it's just that the TP is 2 years old and has been in two users' hands. (shrug)

Michael1980 · #10 Post by **Michael1980** » Sat May 06, 2006 11:42 am

No, not overclocking.
Anyway, the BSOD's on my laptop (don't know about the rest) only seem to happen while on battery power. Ati Powerplay causing this? Turned it off.

Before, I got a good advice to check whether the drivers were causing this. I did the Windows Verifier and my BT pc card came as a culprit. Then, I had a what seems to be a faulty SD PC card adapter causing BSOD's. Now I have a CF adapter which works okay.

Anyway, looking at other people, it seems they may have solved the problem by installing IBM memory. That is why I assumed it is the Crucial memory.

Any BSODs since turning off PowerPlay? From what you found, the card (and its drivers) could be a culprit, but happening only on battery power is an interesting clue....

FWIW, I don't do the "change refresh rate" power saving in my power profiles. Besides the annoyance of the blinking, I didn't think it a gentle practice for the display circuitry.

Michael1980 · #12 Post by **Michael1980** » Sat May 06, 2006 3:50 pm

Well I am fully docked and working so cannot really check it out.
Does anything else change when running of the battery? The BSOD's usually happen when the proc. was set to "very slow" and I was changing tabs very quickly in Firefox.

davidspalding · #13 Post by **davidspalding** » Sat May 06, 2006 10:44 pm

No, really. Please ... don't BSOD on my behalf.

Michael1980 · #14 Post by **Michael1980** » Wed May 10, 2006 7:29 am

Just had a BSOD (something about MountMgr.sys) on AC power.
Do you think it is the graphics driver?

davidspalding · #15 Post by **davidspalding** » Wed May 10, 2006 10:30 pm

MountMgr.sys doesn't seem to be related to your video. But there are some instances in which it can be involved with a crash.

http://support.microsoft.com/?kbid=892926

Your instance could be different, but I really kinda wonder what your IT department thinks about this.

Michael1980 · #16 Post by **Michael1980** » Sat Jun 10, 2006 12:21 pm

Hi, sorry if I made it unclear, but the Thinkpad is actually mine. Ie my work and home computers are virtually identical!

Basically it came to this. I will not get BSODs when I turn the paging file off (of course I will get some other nasty out of memory stuff, especially running iTunes). Does this mean that the culprit is the hard disk?

Regards

DIGITALgimpus · #17 Post by **DIGITALgimpus** » Sat Jun 10, 2006 12:59 pm

That could be a sign of HD corruption... what is the error on the BSOD?

Corruption could be either filesystem, drive going bad, or a drive controller issue (motherboard).

Best bet would be to run PC doctor, and scan the disk.

http://www.memtest.org/

Download memtest86+ iso, burn a CD-ROM and boot on. It will test your memory. If it reports any error, it's a memory issue.

Michael1980 · #19 Post by **Michael1980** » Wed Jun 14, 2006 10:56 am

I ran the memtest from floppy. Left it overnight, in the morning the screen had a lock pictured (like that when you enter you pin code) and the sleep, num lock, caps locks lights were blinking. What does that mean?

Pc Doctor returned no error.

When the BSOD happens it is usually the "kernel stack inpage error" with the code being loads of zero's. Sorry don't remember it exactly.

If the Video Card is to blame, what error number would I get?

At the moment I am getting 0x00000077 blue-screen error.
I changed the crucial sticks, to no result.
Now, I put my old original hard drive in to see whether it is the hard drive corruption that is the culprit here.

JHEM · #21 Post by **JHEM** » Mon Jun 26, 2006 9:21 am

It's an XP software error, not a hardware error!

James

Michael1980 · #22 Post by **Michael1980** » Mon Jun 26, 2006 5:29 pm

To be honest, Microsoft gives no real explanation for the error. But it does suggest (somewhere in that article) that it is due to a hardware malfunction. Really difficult to pinpoint.

So, am I right in thinking that the Video Driver error is not 0x77?

Regards and I will hopefully get to the bottom of this!
