Hi all,
About a year ago I have built a system with the following components:
- Gigabyte GA-P55A-UD4, F15 BIOS. SATA Controllers in AHCI mode.
- Intel i7-860
- 4x Kingston KVR1333D3N9 (2GB each, for a total of 8GB)
- ATI HD4870
- Samsung Spinpoint F3 1TB
- 500W Enermax powersupply.
- Win7 x64 SP1
Everything is running on stock settings, no overclocking, no manual voltage adjustments or anything like that. System used to be rocksolid with no hickups whatsoever. Until I added an SSD.
First SSD I have tried was a Vertex 2 120GB with the latest firmware (1.32). This introduced the following two problems:
- About 10% of the time, the system would crash and reboot at startup. Not even a BSOD (or at least not visible), just an immediate reboot just before the windows desktop appears.
- About 90% of the time, if the system would resume from sleep it would crash with a BSOD. Also instant reboot, despite the cleared setting for automatic restart in advanced system settings.
In both situations, the system would not recover after a reboot and would keep crashing and rebooting just after desktop appeared. Only a cold start would "cure" it.
However, if it did boot, I never suffered any random crashes or BSODs. Just the two situations I described above. Considering the countless reports about sleep and resume problems with the Vertex 2, I decided to change the drive for a different brand.
Now I have an Intel 320 160GB. The first problem still persists:
- About 10% of the time, the systems crashes just after startup, just before the desktop appears. No visible BSOD, just an immediate reboot. And again, if this happens, it keeps on crashing and rebooting just after the desktop appears unless I manually switch it off and cold boot it. If it *does* boot, it seems as stable as ever. Never any random lockups or BSODs.
- Resume from sleep works. Never had any immediate BSODs or lockups.
- After resuming from sleep, the problem I sometimes get at startup, also appears at shutdown. Again a cold boot is required to recover.
Things I have already tried without any effect:
- cleared the system of any unnecessary peripherals (HDs, DVD Burner etc.).
- tried both SATA controllers (Intel and Marvell), just the SSD on the first port.
- since the event log shows BCCode 124, manually set QPI/Vtt from "auto" to 1.17.
My guess is some voltage is -just- above or below what the SSD or SATA controller can handle. Im surprised that an SSD triggers this problem when a 7200rpm harddisk doesnt give me any troubles. Also surprised that a reboot is not enough and the systems requires a cold start to get going again.
Anyone have an idea what else I could try?
