OC: Sabertooth X58 + i7 920 D0

[seesee]

seesee,

 

It's a pretty standard recommendation when overclocking the socket 1366 i7 platform to increase QPI/DRAM/VTT (or whatever your particular BIOS calls it) to the neighborhood of 1.3v or equal to your cpu voltage.

 

I still think you're light on the cpu voltage for 3.855Ghz. IMHO you should start your cpu voltage and your QPI/VTT voltage at 1.30v and work your way down from there.

 

I thought I answered the question about bclk and voltage - but I guess not.

 

When you start pushing your bclk you need to consider two voltages;

 

1. NB Voltage - it directly affects your ability to hit sustained and stable bclks above 160

2. CPU Voltage - since your cpu operating frequency increases with the bclk (unless you reduce your cpu multiplier) then you have to juice the cpu at some point. What point that is depends on the quality of the cpu to begin with.

 

oh icc... thanks

 

I keep getting this BSOD message.. what does it mean

ERROR_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.

Hello Guys. I am trying to overclock to achieves the best voltage and BCLK ratio.

 

my current settings are

 

Ai Overclock Tuner: XML

CoreRatio: 20 * BCLK:195

VCore: 1.32

DRAM V: 1.5

 

Auto for the rest

Temp Stable @ 75~80

 

I can't run prime85 for more than 3 hours, any help please? I tried increase the PLL but it just got worst.

 

Stable Settings

=================

21m x 175 @ 1.225V

21m x 180 @ 1.275V

20m x 190 @ 1.28750V

 

 

Questions:

 

** I keep getting BSOD ntoskrnl.exe , can someone help me with this? thanks

 

3) Lastly did I miss out any setting?

 

 

Updates:

I decided to resolve the ram issues later, since the variable that affects BSOD is related to QPI/DRAM voltage.

 

Back to question 2, is there anyway to increase the 175 BCLK without increase the CPU Voltage?

Did you adjust the VTT at all?
