I have been playing and fixing PCs for nearly 20 years, but I this was my first time trying to OC one. Just my luck, I get two steps out of the gate, and fall on my face! So, could you fine gentlemen tell me where I misstepped?
Optimal i7-930 Settings:
CPU freq: 2.8 Ghz
DDR3 freq:1600 Mhz
QPI: 4.8 GT/s
HT: enabled
QPI freq: auto
Memory Ratio: auto
XMP: enabled
cpu multiplier: 21
Blck: 133
Spread spectrum: enabled
PCI Freq: auto
PCI-E freq: 100
Turbo mode: enabled
Vcore: By CPU vid
DDR3 Voltage: auto
IOH: 1.10 V
QPI uncore: Default
Level 1 OC (Preset OC option on motherboard):
CPU freq: 3.36 Ghz
DDR3 freq:1600 Mhz
QPI: ~5.7 GT/s (Forgot to write this one down, so I am unsure of the exact number, but it was OC'd)
HT: enabled
QPI freq: auto
Memory Ratio: 10
XMP: enabled
cpu multiplier: 21
Blck: 160
Spread spectrum: enabled
PCI Freq: auto
PCI-E freq: 100
Turbo mode: disabled
Vcore: +20 mV
DDR3 Voltage: auto
IOH: 1.10 V
QPI uncore: Default
**This is how the PC arrived, and ran for years. It became unstable with this mild OC about a year ago. The system would seemingly run fine for days, or even weeks of casual use, and then it would randomly blue screen. (Now that I think about it, the inconsistent nature of the problem would be consistent with memory issues.)
My OC Settings:
CPU freq: 3.57 Ghz
DDR3 freq:1360 Mhz
QPI: ? (Wouldn't boot, so Idk this figure)
HT: enabled
QPI freq: 4.8 GT/s (I lowered this in accordance with a guide I read)
Memory Ratio: 8 (I lowered this to ensure the memory didn't get OC'd, also recommended in guides I read)
XMP: enabled
cpu multiplier: 21
Blck: 170 (I increased this by 10, a small increase)
Spread spectrum: enabled
PCI Freq: auto
PCI-E freq: 100
Turbo mode: disabled
Vcore: +20 mV
DDR3 Voltage: auto
IOH: 1.10 V
QPI uncore: Default
Now, what happened.
The computerredacted!
It started, then immediately shut down. Then it started again, and ran for about a minute, and shut down again. Then it would just repeat this minute on, shutdown cycle. There is no video or beeping during this time. So, I was like ohh shit, I blew something up, which I did. I swear if it wasn't for bad luck, I wouldn't have any.
Long story short, I diagnose the problem, and my 2nd memory slot is fried. If I plug memory into it, alongside other memory the system does the above. If I plug a single stick into that slot, the system won't recognize it all, and will start beeping (notifying me I have no memory)
Currently, I am running a stress test with the e5620 at stock speeds. It's been going 30 minutes now, and no issues.
My 2 cents,
I don't think I screwed up, but I am certainly no expert on OC'ing. I am thinking that memory slot was going bad anyways, which potentially caused my previous instability issues.
Currently I have the E5620 that I got in the mail today, and have been running an aida64 stress test at stock.
