BSoD/Vertical Gray Line crash
**Minidump attatched
Here's my system:
Mobo: Asus M4A78 Plus (latest bios version 1214, also latest chipset update)
Processor: AMD Phenom II X2 550 BE (i planned on OC'ing, but have not yet because of the crashes)
Overclocking: Not yet because the system is already unstable.
Vid Card: SAPPHIRE 100283L Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.0 x16
RAM: G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel
PSU: Thermaltake toughpower W0103RU 600W ATX12V / EPS12V
HDD: Western Digital Caviar Black WD5001AALS 500GB 7200 RPM SATA 3.0Gb/s 3.5"
OS: Windows 7 64-bit
I've got a 3rd party Zalman CNPS10X Extreme cpu cooler on the phenom II. (which I have already taken off, removed the paste, and reapplied much more carefully).
I've got the latest of all drivers/software (all Win 7 64 bit compatible). I have completely reseated every component.
Problem: Annoying gray vertical line/restart (various colored vertical lines suddenly appear and then the system restarts) OR BSoD which can be counted on to occur VERY often. The gray vertical line issue has been widely reported by other ATI 5XXX owners. I ruled out this problem by first trying all of the proposed tweaks in that thread, and finally by replacing my Radeon by an old nVidia... the crash persists but manifests itself as only a BSoD and not vertical line crash (I assume the difference here is just the same crash but different expressions of it because of the vid card switch).
Testing:
*Memtest86+ v4.00 ran overnight (12hrs) with 0 errors.
*Prime95 crashes for small FFT's, in place large FFT's, and Blend. At first it gave me the Fatal Error: rounding was 0.5, expected less than 0.4. I manually set the ram to 400 frequency and 5-5-5-15 with 2.0 volts (the specs recommended). The rounding error goes away but the system still crashes (either lines or BSoD) before 15 minutes pass.
*Since Prime95 crashes quickly, it isn't surprising that all games i've tried also crash.
*All temperatures are normal: GPU never above 65C, CPU never above 39C, mobo never above ~33C.
