I've added 2x 1GB more ram to my system, and now I'm experiencing some stability issues that I've never had. Computer lock-ups, black artifacts on the monitor (only on boot up as the Vista Login Screen shows up), and even a couple BSOD's.
I'll try to give as much detail as I can.
Original setup:
Motherboard: EVGA 680i LT SLI
Memory: 2x 1GB Crucial Ballistix DDR2-667
Processor: Intel Core2Duo e6420
Operating system: Windows Vista Premium 64-bit
The memory was set at 667mhz and timings were 3-3-3-12 at 2.2v
Processor was slightly overclocked to 2.66ghz to sync with the memory; kept at 1.35v
New setup:
Motherboard: EVGA 680i LT SLI
Memory: 2x 1GB Crucial Ballistix DDR2-667 + 2x 1GB Crucial Ballistix DDR2-800
Processor: Intel Core2Duo e6420
Operating system: Windows Vista Premium 64-bit
To match the original pair of memory, I lowered the frequency of the new memory down to 667mhz. Also since the DDR2-800 is rated at 4-4-4-12 timings by crucial I increased the timings to 4-4-4-12 for all memory. Kept at 2.2v
And then... lots of lock-ups, black artifact lines on vista load screen, and a couple BSOD's (when I get a BSOD it usually happens within 10 secs of logging into Vista).
As memory being DoA is s not uncommon the first thing I did was run memtest. This took about 14 hours as I had to check all the sticks one by one.
Memtest results:
All 4x 1GB Sticks: Pass
Each Stick Individually: Pass for each one.
Since there's nothing wrong showing up in memtest, I'm lost as to what could be wrong. Often the computer seems to be running fine, but when I try to run some memory-based applications such as SuperPi, it's a hit and miss. SuperPi works only about half the time, and errors out the other half. I don't know what this means exactly, but I'm assuming that's an issue there.
I was also wondering if power could be an issue since more memory does consume more power.
My PSU and other components:
PSU: Corsair HX520
GPU: EVGA 7950GT KO
Other Stuff: WD HDD, Lite-ON DVD-RW, FloppyDrive, 3x 120mm Fans, Intel Stock CPU Cooler, 2x 40mm NB, SB fans
But as far as I know the Corsair HX520 should be more than sufficient for my components.
I'm really stumped on this matter, so for now I've removed the 2 new sticks.
Does anyone have any ideas what's wrong or anything else I should do to further assess the problem?
