Overclock Questions

With the RAM at 2.0v, still doesn't want to work?

You can only change it between 7 and 6, you want it to go higher, not lower, so there's nothing we can do with that :cool:
 
Your memory will handle 2.1volts , what are your timings set at ? I'm running my XMS at 2.1 volts but had to loosen my timings from 4-4-4-12 2T to 5-5-5-18 2T in order for a stable oc. I'm running my E6850 at 3700mhz . One other key change would be to bump up your NB voltage alittle.

I'll try 2.1v, thanks! :)

You have the 6400, were as I only have the 5400, maybe that's what's up? Also, what is your multiplyer at, mines locked at 7 and 6, 6 is pointless anyway :cool:

NB voltage, what would that?
 
I'm running my NB at 1.4 volts anything past that and it gets too hot and becomes unstable, without adding an extra fan to blow on it .
 
Only way to check or set it is in the bios. I know your running a Gigabyte board and mine is Asus so I don't know where to tell you exactly. It should be under the advance tab in the bios though.
 
Danny check out these settings the MCH is your NB
Advanced BIOS Features
- Disable CPUID Max to 3
- Disable No-Execute Memory Protection
- Disable C1E
- Disable TM2
- Disable EIST
- Disable Virtualization Technology

PC Health Status
- Disable Smart Fan Control Method

Motherboard Intelligent Tweaker (M.I.T.)
- Press Ctrl+F1 for Advanced Settings
- CPU Clock Ratio (CPU Multiplier) at 7x
- CPU Host Frequency (FSB) at 430MHz
- PCI Express Frequency at 100MHz
- Disable CIA2
- System Memory Multiplier at 2.00 (1:1 Ratio)
- DRAM Timing at 5-5-5-15
- *** DDR2 OverVoltage Control +0.2V (2.0V) ***
- FSB OverVoltage +0.2V (1.4V)
- (G)MCH Voltage +0.1V (1.55V)
- *** CPU Voltage at 1.274V ***

*** Your settings may vary. Some may achieve stability at higher voltage, whereas some may achieve stability at a lower voltage. ***
 
Thanks Colt!

I seem to be able to get 2.8Ghz on stock volts, it's my RAM that craps out, I think I'll try 2.1v on the RAM...
 
The RAM is only running at DDR2 808, voltage should not be an issue. It does not sound like a RAM issue to me.

I would also eventually lower the RAM timings, as those are very high. But I would wait until you get your processor where you want it first.

Bearing in mind this ram is 667 MHz not 800 MHz, i think voltage increase is necessary
