Sandy Bridge default volts? Overclocking help required

Firefox35 · 11 Jan 2011 at 18:19

I want to try overclocking my 2500k sandy bridge but would like a little advice, what are the default volts for an i5? I plan on trying these settings on my Asus motherboard.

Disable turbo

CPU core to 1.25 (what's the default voltage?)
CPU PLL to 1.8
BCKL set to 100
Memory voltage 1.55

What do I set the VVCIO and VCCSA volts to?

Any other advice would be very much appreciated chaps.

Each chip will be different for its intel specified setting. it'll probably say it in the BIOS somewhere. check Gibbos thread for overclocking tips

Hi doesn't mention the default volts for VVCIO and VCCSA volts and I don't want to chance leaving them set to auto.

Edit: I'll stick the notes in as well as 1 is fairly pertinent, especially as regards Vcore which isn't listed in the datasheet yet.

Notes:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical
data. These specifications will be updated with characterized data from silicon measurements at a later
date.
2. VCCSA must be provided using a separate voltage source and not be connected to VCC. This specification is
measured at VCCSA_SENSE.
3. ±5% total. Minimum of ±2% DC and 3% AC at the sense point. di/dt = 50 A/us with 150 ns step.

Thanks Jokester, got it running at 4.2Ghz, ran prime for 30 minutes and temps didnt go above 60c
