Well, I've searched all over and can't seem to figure this out so I'm starting a thread. Computer specs at the bottom of post.
I put this computer together about a year ago now. After I had everything up and running fine, I bumped the CPU:FSB ratio up to 5:4 at the default 200MHz (quad pumped) FSB. This had me running it at 3.0GHz. I then overclocked the memory just a little and had the CPU at 3.14GHz (pi, not on purpose).
I left it like this for a good 6-8 months. Never any problems. In the summer while gaming, the hottest the CPU ever got was 53 degrees. Never any crashes, everything was perfect. Then I bought a Seagate Barracuda 7200.7 160GB SATA HD, and had a hell of a time getting it to work. I finally worked after turning off the SATA RAID in the BIOS, and making sure it was plugged into SATA1 port.
However, while trying to get the HD to show up, I turned everything in the BIOS back to what it came like.
I haven't been able to overclock since. I haven't tried more than a few minutes at a time the last couple months, until today, where I spent about an hour trying everything. If I switch the CPU:FSB ratio to 5:4 while keeping the RAM at 200MHz, it gives the "System failed due to CPU overclocking" voice message. If I keep the ratio 1:1 and overclock the RAM more than 10MHz, I get this too.
The Vcore is currently at 1.525. However, I tried everything all the way up to 1.6 without success. I've tried all sorts of options in the BIOS (Turbo On/Off/Auto, PAT On/Auto, etc). Nothing changes this at all. I've changed the RAM timings a hundred times. Everything from 2-2-2-5 to 3-5-5-8. No difference.
The only thing I can think of is if the SATA HD is somehow messing up my overclock? Nothing in the system has changed since then. It's not a matter of heat, as even with a 1.6 Vcore, I was still getting around 38 idle / 51 load. Originally I had the Vcore on auto.
I really want my 3GHz back, and I'm out of ideas. Please help!
