Overclock i7-920 or upgrade CPU?
Hello! :)

I would like to raise the performance of my old machine and I would like your advice.

The specs of my PC:

Motherboard: Gigabyte EX58-UD5 (Socket 1366) rev1.0 (BIOS F13)
CPU: Intel i7 920 @ 2.67GHz
RAM: 18GB DDR3 @ 1600MHz (9-9-9-24) [ 3 modules of 2GB Corsair CM3X2G1600C9 & 3 modules of 4GB Corsair CMX4GX3M1A1600C9 ]
Operating System: Microsoft Windows 7 Ultimate (x64) SP1 Build 7601
GPU: Gainward GeForce 9400 GT
PSU: 625W Enermax MODU82+ EMD625AWT
Disk drives:
- 1TB Crucial CT1000MX500SSD1 (OS drive)
- 3TB Seagate ST3000DM001-1ER166

I should state that I have no idea on OC, I am a total newbie and I have already made a disastrous attempt to OC. I had found somewhere someone posting his BIOS settings for the same mobo and cpu as mine in order to achieve 4.2GHz. I just entered the values into my BIOS. Result: Windows booted, then I had several error messages and after a few seconds BSOD. OC killed my SSD OS drive (Crucial MX500).

Now I have a new SSD drive. My question: Is OC safe? If I can *SAFELY* OC my CPU to 3.5-3.7GHz then I would like to try it. But if there is the slightest possibility to kill my SSD again then what CPU would you recommend me to buy? I do not want to spend more than 100euros.

Thank you very much in advance for your help! :)

The biggest issue with the first gen "i" series cpus were just their low clock speed. They're very easy to overclock and there are tons of guides. You should definitely overclock it before you jump to upgrading.

Also, i believe your system supports triple channel memory. Your system would probably be faster if you took all the two gig sticks out and just ram with 12 gigs of matching ram.

Increase performance ... in what? You can OC your CPU to 1000Ghz but with a 9400GT you're not going to be playing games if that's your intent :p

If it's for non-gaming things, you already have the board to OC, so OC. If it doesn't get you the gains that you want then you should upgrade.

Yes, OCing is safe if you do it correctly and can cool it/don't go overboard on the voltage.

Thank you both for the quick replies! :)

I am not interested in playing games. I use this machine as a Digital Audio Workstation.
I do understand that OC is the most logical thing to think first before upgrading... but.. is it 100% safe? I do not want to brick another SSD!! :(

I think all my RAM modules are triple-channel...

Did you kill an SSD or did you corrupt data and lose it? You should be running backups anyway. :)

OCing incorrectly and being unstable can corrupt things, but you won't kill a drive.

Yes, I bricked it.. I could see it in BIOS but could not access it even as an external disk in another PC.. Believe me, it didn't get corrupted.. It died!

An unstable OC won't kill your drive. If your PSU isn't up to snuff then it can cause things to die. Short of that it was just a coincidence it decided to die when you tried to OC.

Take out the corsair sticks and OC the snot out of it. If you don't want to risk corrupting a drive you should just OC with a Windows bootable stick...or Linux.

Never heard of a drive being killed by overclocking but I've seen a few SSDs fail just in general.

Overclocking is safe so long as you know what you're doing, and there isn't much to know. Read a guide or watch a youtube video or two on it and then come back and ask us your more specific questions.

I've had three Sandisk Ultra II SSDs die during my overclocking experiments over the last few years. They don't seem to like sudden hard-power-off events when your PC locks up.

My Samsung/Intel/Fusion-io, and even SanDisk Extreme Pro SSDs all have worked fine through all of it. It's just each time, one of my SanDisk Ultra IIs would fail.
