BSoD hours after clean Win7 install, rig is "seasonally unstable"

That is Memtest86+, the + just blinks and I snapped a picture when it was gone. Silly feature in my opinion.

Here are my voltage and RAM shots as requested although I'm not very good at interpreting them. From left to right: default voltages, actual voltage?, RAM timings, and a hwmonitor image.


DDR VTT or whatever it's called is not listed although it appears it should be. I ran HWMonitor and saw a VIN at .88V that is most likely the VTT? Also the RAM is rated for 1.5v but there isn't an option to set it below 1.6 manually.

And the requested images from CPUID

Your NB Voltage control is on the outside of the requirement that it be within 0.5 V of the DRAM Voltage. Bump NB Voltage to 1.2 V to go with the DRAM 1.6 V so they are within 0.4 V. (If you cannot get 1.2 V, choose the closest value that is higher, i.e. 1.205 V instead of 1.195 V)

NB Voltage is basically VTT Voltage, by the way.


Post back whether that increases stability.

Not to be a skeptic but this review with the same model motherboard shows pictures of the BIOS with both.

I'm referring to the image below. Just want to be sure of this since I've never touched voltages before.

I bumped up the voltage to 1.2 and did a few minutes of memtest test #5 and within 3 minutes there were 21 errors. This is across all 4 gigs, so I guess I'll switch out a stick tonight.

Sorry, I was not as clear as I should have been. There is a VTT Voltage that feeds the memory termination logic. There is also an Intel VTT that provides voltage to the CPU Memory Controller much as the NB Voltage does. Those are the two that are interchangeable. Since you have an AMD board, that is why there are VTT and NB Voltages; your VTT is for the Memory termination logic.

Does not look like a simple Voltage bump is going to resolve the errors. You likely have a faulty module or slot. Let us know how the RAM swapping goes.

Hi all, over the past few days, I've been running a battery of memory tests. Here's my results which seem a bit inconclusive. Also the RAM pairing in my rig is 1+2 and 3+4.

1. RAM 1+2, slot 1+2 - Many errors mostly test 5 and some 7
2. RAM 1+2, slot 1+2 with voltage 1.2 - quickly showed errors test 5
3. RAM 1, slot 1 - 1-2 errors per pass on test 7
4. RAM 2, slot 1 - 18 std passes, no errors
5. RAM 1, slot 3 - 6 passes test 7, no errors
7. RAM 1, slot 3 - 12 passes std test, no errors
8. RAM 1, slot 1 - 6 passes test 7, no errors
9. RAM 1+2, slot 3+4 - 7 passes std test, 20 errors on test 7
bluescreen during windows usage
10. RAM 2, slot 3 - 13 passes std test, no errors
11. RAM 2, slot 3 - 5 passes on Windows Memory Diagnostic extended, no errors

I guess I need to go back and test RAM 2 in slot 1 to make sure it was indeed error-free

Looks like good troubleshooting. Make sure slot 1 is good as you mentioned. Also, you may want to set aside the suspected bad module for now and see if the other module causes any issues.

My guess is RAM 2 is good and RAM 1 is bad. RAM 1 may not show errors on all tests depending on whether Memtest86+ checks the bad parts of the RAM or not. The fact that you had errors at any time running only 1 shows that it is likely bad, but it could also be the slot, as you also suspect.

Nice work!
