Finding Max multiplier.

post #1 of 3
Thread Starter 
ATM i've got 4 SB 2600k rigs running here. I have WC the main rig all of the others are running as servers/workstations with stock cooling.

The chip i have in my main rig is pretty lousy, it will run stable 4.6Ghz @ 1.38 / 4.8Ghz @ 1.44, but anything over that and it wont even post. Tried 49x with 1.56v, but wont even post.

The main rig is WC and the cpu block is connected to everything else with "solid pipes" and not the ususal tubes, so to remove the cpu block i need to drain the system.

My question is then: Is it safe to put 1.56v and check for the max multi on the other systems running stock cooling? I will ofc not load anything, just verify that it posts and loads into Windows, then shut it down or is there some other way to check for the max multiplier?

Thanks

This should help:

Briefly:

1. set vcore to 1.55v
2. disable EIST, C1E and C-states
3. disable HT and 2 cores (to prevent overheating)
4. increase multiplier

It doesn't have to actually boot into Windows; as long as it gets to the OS options, it should be able to run at that multi given sufficient voltage and cooling.

It's a pretty quick process; given that you'll be using the stock heatsink, definitely disable HT and two cores.

Yea, that's the method i've been using on my main rig. Was just wondering if it was OK with the stock heatsink. With that solved it looks like i'll be testing some more 2600k's.
