Bsod help

ste-sim2x9 · 29 Oct 2009 at 15:54

I've been getting bsod's here and there but now they are happeninga bout 2 times a day. These are what i keep getting,

Stop:0x0000007F
or
Stop:0x0000001E

What are these caused by.

I have took my ram out and i am going to memtest it tonight but how many passes to you have to give it. I tested 3 of the sticks today and did 2 passes on each with no errors.

Could you list your spec?

Make sure you're using the most current version of memtest.

Also, if all sticks pass with zero errors (test #5 is usually the killer) after a few passes on each stick try testing with 2 sticks installed and then 4 sticks. If you do get a failure with 4 sticks it may be that your NB voltage (MCH) needs upping slightly – or a faulty slot or other....

Additional: If your system is clocked at all set everything back to stock.

It's also advisable to reset the BIOS and load optimised defaults as this can sometimes eradicate BSODs.

Have you ran Chkdsk?

My spec is,

Microsoft Windows 7 Home Premium
Intel Core 2 Quad Q6600, 2400 MHz
Gigabyte GA-EP45-UD3P
8gig (DDR2-800 DDR2 SDRAM)
ATI Radeon HD 4800 Series (1024 MB)

I have tested all sticks one at a time and tested two sticks at a time with no errors. I have yet to test all four stck as you know its takes time. My system is at stock settings at the moment and ive loaded optimised settings. I have been useing my computer with just two sticks in for a 5 hours with no bsod's so if i will have to test all four sticks together and then i don't know what to try.

Try increasing the memory voltage. Find what it is rated to from the manufacturers website, and manually set it to that. Normally when you've got all 4 slots used, you need to increase the voltage to get it to run stable.

4 sticks lowers stability on most systems for some reason... Needs more DRAM voltage, and potentially a touch more NB voltage. only ever increase the NB voltage by one notch at a time, and check temps with something like realtemp, coretemp, speedfan, everest, your choice. Afraid I don't know much about what is a stock voltage for an intel NB though.

Have you upped the MCH (NB voltage) since installing 4 sticks? (As i mentioned earlier it may benefit from this increase.)

I have found most systems require the MCH to be knocked up an increment or two to get a system stable when filling all the slots.

Using 4 sticks puts additional stress on the memory controller and as a result sometimes requires a touch more juice.

Also check that your memory voltages are correct and you may want to consider slackening the timing slightly while your trying to get the 4 sticks stable.

I have now put all 4 sticks of ram back in my pc, the ram has 2.3v on the sticker but my bios set it to 1.8 so i've raised the voltage to 2.0v and raised the mch from 1.100 to 1.200. Would that be a gud move or what, i will memtest tonight with all the ram installed to see if it passes with no errors or bsod's.

I would raise the voltage to 2.2V/2.3V for now - as this was probably your problem.

You could always experiment with lowering it once you feel the sytem is stable - but for now it's best to run the memory at it's recommended voltage as you're having stability issues.

my brother was getting this a couple of days ago, turned out to be a virus

i know its a stupid question to ask but sometimes its what causes the problem.

1.Is the windows 32bit with those 8gb ram inside?
2.have you got latest motherboard bios update?

ste-sim2x9 · 31 Oct 2009 at 08:05

My operating system is windows 7 home premium 64bit and is retail i brought and installed last week but the bsod's were happening while i was using the beta. I have not upgraded the motherboard bios for quite a while. I have no virus and have my anti virus and firewall updated and working fine. Since raising the ram voltage i have not seen a blue screen yet so fingers crossed that may have been the problem.

I would hope your problem is sorted now bar fine tuning of the voltages if desired.

It sounded like a voltage problem and as you were running 0.5V under the recommended voltage, plus the MCH voltage was on auto using 4 sticks it makes sense that it would struggle.

Upping the MCH is always advisable if you’re having stability problems when running 4 sticks and the fact you upped this setting at the same time as your memory voltage may also have contributed to the renewed stability.

As i mentioned before once you're confident that your system is stable (give it a week or so) try dropping the memory voltages incrementally until it buckles as it would be beneficial to run lower than 2.3V (but not crucial).

Once you have found your minimum memory voltage for stability you could try lowering the MCH - but if you’ve only knocked it up one increment i wouldn't worry too much about this.

Or you could just leave well alone and let it run as is…
