Stability problem 4 sticks RAM

[shepardx]

Hi! This is my first post I have read A LOT here, I love the oc, love the hardware and everything related to the computers. Bla bla, ok.

The problem is with my PC in stock:

GA-880GM-UD2H
4x2GB Adata gaming 1333
Phenom x2 555

Everything in stock, bought less than a month ago.

Windows continuosly throws me BSOD's

PAGE FAULT IN NON PAGED AREA (mainly this)
BAD POOL HEADER
MEMORY MANAGEMENT (The rarest)

All are related with memory afaik.

In linux, all goes well, except running mprime (prime 95), a blend test with a lot of ram fails, maybe more than 5000MB

I have tried memtest overnight, and it passes. Tried test 5 several times, and passes.

But the weird things here are:

- Using only 2 sticks of RAM, it works very well. Using 3 or 4 causes these problems
- Sometimes the 4 sticks works well, and then, these issues aren't repetable. I can left the PC working HOURS and all is ok

The "pattern" to follow to get crashes, is leaving the PC off several hours, and then when you power on, you get the BSOD almost always.

Then, all these things discards some posibilities

- Isn't temperature
- Isn't windows/drivers

I have tried upping the vdimm because the memory says 1.65-1.75. Same results. Well, I have tweaked every voltage... (This was the only solution I found seaching in internet..)

The mobo has the latest bios (F8)

What can I do? I am getting desperated because I can't repeat the problems to diagnose it.

Thanks!

PS: Sorry if my english isn't any good.

Are you o/cing at all ? Did you enable the other 2 cores of that chip ?
What are you RAM timings ?

(post a CPU-Z screenshot)

Have you ran memtest86+ overnight to check the RAM ?

[shepardx]

Thanks for your answer

As I said before,

-Stock settings (No oc and no unlocking)
-RAM timmings, hmmm sorry I don't have CPUz at this moment, but they are at default SPD, 9-9-9-27 or something like that.
-Memtest overnight, 8gb passes again and again.

I will post that cpuz screenshots later :P

Edit. Double post sorry ¬_¬

But I can use this post to say the other components in the rig

9800GTX+
Corsair HX620
A dvdrw
2 sata hard disks

Bump CPU-NB voltage to 1.25v, then see if the problem persists

[shepardx]

Woah, the mythical beepbeep in my post /cry /cry

I will do that and test a lot :P

And here are that screenshots btw

I had to raise the volts on the ram (4x2Go) just a little in order to have it run stable at it's rated speed and timings.

I did the change of CPU/NB, also Vdimm, ALSO upping volts here and there. The same happens.

I have a new possible theory, a way to repeat this behavior and to "correct" it:

-My PC is off, without energy to the PSU, maybe a few hours, or overnight.
-I plug the cable, and start the PC.
-Then I get memory problems.
-If I try a restart, or do some tweaking in the BIOS, I get the same problems.
-If I poweroff the PC, without unplugging the cable, and power on, the PS works stable.

What is happening!? I am wondering about the PSU with this behavior, but I am unsure. I will test without GPU (without hope...)

Some ideas?

Is your battery low ? If you unplug the cable from the PSU (why?), then the board is using the battery to keep the settings in CMOS. If you have it plugged in, then it does a trickle charge to keep the settings.
This is just a guess though. That sounds like a odd problem that I don't recall having seen before.

Try two sticks at a time again and test with Prime Blend for 4-6 hours, then do the same with the other two. I realize you said two work fine but four doesn't, but maybe you should play it on the safe side

No, the mobo is like new, the settings doesn't dissappear

I have tried! And everything works. I will do more tests, but I need to put my computer off some hours before this.

I have confirmed this behavior, a cold boot causes BSOD. I must shutdown and start again to get the 4 sticks stable. As far as I have tested, this works always :S

Mobo issue...if it was IMC you'd have the problem all the time.

My 890GX board does the same with two sticks if I run over ~1700, didnt even try four.

Hmmm, tomorrow in the morning I will try 2 sticks, and in the night the other two.

I am suspecting about the mobo too. But, here the warranties are a little bit 'difficult'. How can I explain the issue? Commonly the people in the stores aren't very technical, and probably they will refuse to give me warranty without good arguments =(

I am wondering about a memory compatibility issue, but I don't have more RAM to test :S

Email Gigabyte, they will probably be the most help to you

[shepardx]

Bumping.

After more tests, I found the "bad" pair of sticks. And I say "bad" because I tested it with memtest and found errors. But after shutting down, and power again, they doesn't show any errors. The other pair doesn't have that behavior, or at least I haven't been found any issue... yet

I am wondering if that pair will qualify for warranty, because sometimes works, and other doesn't work. Maybe I will try to check that pair with other mobo in the weekend.
