i7 950 OC'ed - Need Advice

post #1 of 5
Thread Starter 
Howdy,
I'm running an i7 950 on a gigabyte X58A-UD3R rev. 2.0. I have 6GB of 1333MHz Corsair XMS3.

I came home from work today and my computer was off. I always put it into sleep mode when I go to bed. I can't remember if I actually shut it off last night or not... but when I booted, it went to a black screen with a flashing grey cursor. We had a storm last night and power might have gone out - would a power outage in sleep mode cause the first boot to do this?

Just in case that's a no (and even if it could), I've posted my settings here for my 3.8GHz OC. Just wanted some input since I am pretty new to OC'ing the i7. Thanks a lot guys:

Note: If it's not listed, I didn't find it important and/or it's at default!
Code:
Clock Ratio: 23x
QPI: x36
Uncore: x18
BCLCK: 166
Memory Multiplier: 8
PICE Freq.: 100
CPU Clock Drive: 800mV
PCIE Clock Drive: 900mV

LLC: Level 1
CPU Core: 1.25
QPI: 1.235
DRAM: 1.64

RAM: 7-7-7-20

Turbo: off
Cores: All
Multi-Thread: on
CIE: off
C3/C6/C7: off
Thermal monitor: off
EIST: off
PROCHOT: off
Few questions:
1. My RAM is rated at 7-7-7-20 1.65 volts. This motherboard only does 1.64 and 1.66 volts. I've heard setting it to 1.66 is OK... is this true?
2. Would a lower clock ratio and higher BCLCK be a better choice? If so, anyone know a good combo to get the max speeds out of this RAM? I am only using this ratio and BLCK to get the full 1333MHz from the RAM.

Thanks for the input guys!

I don't know what to tell you about the black screen with blinking cursor but it may be related to a power spike which caused the computer to turn off improperly. If it works now the only thing I would worry about is the power supply.

As for the RAM as far as I know a few hundred MHz isn't as noticeable as tighter timings. I could be wrong with this though. My RAM is running @ 1400MHz and I see no holdups with it not running @ 1600MHz.

Running at 1.66 won't kill it. It's not the ideal situation but it could be worse

No your ram timings are based on your bclck. At least mine are. However you can change the multiplier on the ram which is what I did. Mine runs at 1492mhz I think. If you feel that stability is a problem I'd start with loosening the ram timings. That seems to always be my problem. After you do that run intel burn test or OCCT or Linx.

Let me know if that helps

My concern with the RAM voltage is that it is rated at 1.65. I am running it at the factory rated speeds, but with less voltage... could this cause problems or is .01V not drastic to make a change in stability?

My RAM timings are not based on my BCLCK. Only the frequency is.

I run my ram at 1.64 all the time, even at 4.0
