My specs:
AMD Phenom II X2 550
Biostar TA790GX A3+
4 GB DDR3 RAM@1333MHz
Nvidia GeForce 250 GTS 1GB
Western Digital Caviar 160 GB (going to be replaced with a Caviar Black 640 GB w/32MB Cache)
Rosewill RP500 500W PSU (going to be replaced with a 600W PSU)
Windows 7 x64 Ultimate
Well, after a month of running my process as a dual core I've been trying to unlock the quad and have been somewhat successful with a few oddities. My old Phenom II X2 was unlocked, but it went bad (motherboard went out and took the processor with it) so the CPU I have now is actually a replacement. I had a 555 Deneb Black Edition, but AMD sends me a 550 Callisto. Weird.
Anyway, I went into the bios and turned on the ACC function to all cores with core leveling at -2%. When I had the Deneb BE I had remember I had to set the HT link speed to 1.6GHz for it to work stable as a quad so I do that again. Save changes in bios, reset, and Windows boots up. So far everything is look good. Load CPU-Z and it's recognized as a X4 B50 quad. So, I decide to re-run the Windows 7 experience assessment. Everything is working and I'm monitoring my CPU temps ranging between 45-50*C, but the oddity comes into play when it gets to the CPU assessment subsection. Screen goes black and the computer just reboots itself. This happened three times, it cannot complete the assessment as a quad. For safety reasons I have the ACC disabled and the processor back as a dual core.
So, I'm trying to figure out what is happening and why I can't get it to run as a quad.
First, I thought it might be the stock cooler and the CPU temps. Thing is when I ran the assessment again as a dual core the load temps were pretty much the same as when it had been a quad so temperature shouldn't really be a factor of why the quad can't complete the assessment. I also don't think there is much of a difference (if any) between the dual core stock cooler and the cooler the quad uses. I wasn't planning on overclocking or anything, just to run it as a quad.
Second, I began to wonder if my 500W PSU can't handle the processor as a quad, but this is the same PSU I was using when I had my 555 Deneb BE unlocked and didn't have any issues back then. Of course I have a 600W PSU I"m going to be installing when the rest of my parts arrive so if it is a power issue then it should be resolved when I install the new power supply.
Third, I've taken into account it might have something to do with my hard drive itself. It's an older drive I've had forever and a day, but I've become under the impression that it might be reaching the end of its life cycle. It could possibly have bad sectors. I'm not exactly sure, but if the issue with the quad has anything to do with the hdd then hopefully it will be resolved with my new drive and a fresh/clean Win7 installation.
Fourth, I considered the possibility it might have something to do with the corrupt Win7 installation on my hard drive. For whatever reason Win7 has gone bad, but is still working. I know this because a while back I was getting system crashes and BSODs so I tried loading up event viewer to check the system error dump files and the minidumps, but the service wasn't running nor could I get it to start. So, I did a "sfc /scannow" command in cmd to check the integrity of the Windows file system. SFC reports corrupt files (namesly iassdo.mui.dll and a few others) so I can't recall how many times I've taken ownership of the bad files as reported by SFC and replaced them with the originals from my Win7 DVD, but now matter how many times I do it files are always being reported as corrupt by the system file checker everytime I run the scan. A lot of the time it's the same files too. It's the most unusual problem because it doesn't impact system performance at all as all of games and applications run perfectly fine. They don't lock up or crash. Still, it makes me wonder if the compromised integrity of my Win7 installation might be affecting my processor as a quad. I know I will have to reinstall Windows, but I'm waiting until my new hard drive arrives before I go through the trouble of reloading everything.
I'm confused as hell and can't figure out how to keep the quad. I can unlock it and boot into windows just fine (haven't tried running any apps like 3DMark06 yet), but if I run the Win7 assessment then it reboots the computer when it gets to the CPU assessment.
Any ideas?
