Random BSODs and applications crashes on a fresh Win7 install

These are the results from last night, before changing the 'VDDNB Over Voltage' setting, as I ran the test before you replied. Will repeat it with new voltage settings as well.

Attachment 196848

There's a strange thing however, unless I understand something totally wrong: on the screenshot above, the CAS parameters shouldn't be 9-9-9-20 or am I mixing two different things? CPU-Z reports 9-9-9-20 - this is what I set in BIOS.

Also, when I try to get info on SPD during memtest, it tells me "SMbus controller unknown".

Is there any point in changing "chipset voltage"?

Thanks for help!

Have you had any crashes in the last week?

If you haven't had any more crashes, then leave it as it is now.
If you are still having crashes then bump the 'VDDNB Over Voltage' to 1.250v.

Always post any new crash minidumps when you get them, they may have additional information that will help us.

Let us know your status.

Hi, I didn't have any crashes since I set the mems first to 8-8-8-24 @ 1.65v (which was roughly a week ago) and then after your suggestions to 9-9-9-20 @ 1.60v. No blue screens since then. However, 2 or 3 Firefox crashes (v.10 just released, maybe it was actually Mozilla's programme issue). [/quote]

I already bumped it to this value after your previous post. I ran memtest again and did 7 passes without any errors. Funny thing though, memtest would pass every time even when I was getting blue screens - i.e. sometime 2-3 weeks ago.

Another thing: several people report that memtest is showing incorrect timings values in their case - can anything be done about that? Isn't it that it's actually testing RAMs with wrong settings? CPU-Z reports correct values as I set them in BIOS and says also that I'm running dual-channel while memtest says 64bit.

I think, but I'm not 100% sure, that before timings in memtest were what was actually set in BIOS, then recently it would report wrong ones... Does it matter anyway?

Will do if I get BSODs again, hopefully not.

You mentioned that it's possible to get mems running @ 1600 with AMD - could you shed some more light on it? If everything stays fine as it is now, I may try some time to make them run as OCZ claims they should.

Thanks again for help!

Good that your system is stable now.
Firefox has been known to have crashes with their latest updates.

Ram can still cause crashes even if passing memtest86+ (best RAM testing program available) and the RAM can fail a test after passing several times.
Just the way electronics are.

If your RAM timings are on 'Auto' in BIOS they can show different numbers in memtest86+.
You can manually set the first four RAM timings in BIOS, leave the rest in 'Auto', this should let memtest86+ run the test at the right timings.

I'll look for the AMD 1600MHz info and post back.

Since your system is running stable for the last week, you can mark this thread as 'Solved'.
Let us know if you have any questions.

I use the same one, memtest86+ v4.20.
Haven't had that issue or seen it reported here.

AMD IMC and RAM frequency at or above 1600MHz

You can try posting in the Seven Forums Overclocking forum, several of the members with AMD CPUs have been doing this successfully.

Good luck with your 1600MHz RAM settings.

You're welcome.

Enjoy your tweaking, keep a log of your settings, pass and fail, will be a good reference.

We have been having server issues, should be fixed now.
Try to upload again.

Do you have any other RAM you could borrow to test with?
This would be the easy way to rule out the RAM.
