Hi all,
I have run with the above hardware specification since Jan 2007 without experiencing any hardware problems at all. Recently, I upgraded the CPU from an E6700 dual-core to a Q9550 quad. I was a little concerned about doing this, because the MSI mobo I have supports a max FSB of 1066 and the Q9550 is rated at 1333. I don't know enough about these thiongs to know whether that is likely to be problematic? in any case, I Googled around and found that some flavours of the Q9550 had been tested on my mobo (http://www.cpu-upgrade.com/mb-MSI/P965_Platinum_(MS-238).html) so I took the leap.
Early indications were good - Vista detected the new chip and I rebooted when prompted. However, in the space of a week I experienced 2 BSODs - both STOP 101 codes and both while the new CPU was under full load (converting media files). Hmm!
A friend at work suggested that I needed to up the CPU FSB and maybe the VCore also as this would make the CPU more stable. This didn't sound right to me, but thought I'd give it a whirl. I tried upping the CPU FSB (I am a total noob when it comes to OCing). He suggested increasing the CPU FSB in multiples of 20 to start with, so I tried going from 333 (with 8.5 multiplier) to 353. this took the CPU from 2.83 GHz to 3.0 GHz or thereabouts. I rebooted and the PC just displayed a blank screen - no POST. I had to pull the plug, wait a min and power back on and got a message 'your last attempt to OC failed, resetting...'. I then went back to the 'optimised defaults' and left it that way.
Another week, another couple of BSODs with the Q9550 chip, again both whilst under heavy load. Any ideas on what I should do? Have I bought the wrong CPU for this mobo?
Thanks in advance.
