In chrome I get this error:

Sigh. I hope i won't have to reinstall windows.

When google chrome crashes i get a windows DEP popup: Windows data execution prevention has prevented chrome from executing.

phew.

I had a very similar problem and found an answer on a Newegg review. If you change your memory of cpu timings, there is a very good chance that you will not be able to connect to the internet. There is a fix that worked for the reviewer and me. Unplug the ethernet cable and your power cord. Wait a couple of minutes and plug them back in. Works every time for me.

Here is the thing with my PSU the cpu connector is an 8 ping 2x4 connector. The mobo only has a 2x2 connector. So I looked at the adapter and one side has two squares and to cathedrals, the other half has four cathedrals. The mobo connection is for the 2 square and 2 cathedral side, so that is what I have connected. I have tried the putting the 4 cathedrals in there and the end result was the same.

I think someone posted earlier in the threads that you'll need an adaptor from the 2x4 to a 2x2 to get that to work correctly.. That connector is really important.. the board won't boot unless it's perfectly happy w/ the power in that 2x2

[cmgx]

Actually I just noticed that my 2x4 adapter seperates into 2 2x2... one fits perfectly in. And it seems when I turn it on, the fans come on full speed and then quickly slow down.

How do I know if my processor is running to hot?

CPU - 40 degrees C @ Idle
- 50 degrees C @ Prime95

Stock fan.

99% of the time, processor temperature is just a matter of comfort level. It's a function of ambient (room) temperature, your CPU, your heatsink/fan (and how well it's mounted), and the ventilation in your system. With regular old air cooling, your lower bound will be room temperature and your upper will be the thermal maximum for your chip. One way to see if your chip is too hot is to go into your BIOS settings and look at Advanced | Hardware Monitoring. The first temperature there should be "Processor Thermal Margin" (I believe it was renamed from something else in BIOS 0102). That will tell you how many degrees you have until Intel thinks your CPU is too hot. Another way to see the same information (I believe it's the same information) is to load up HWMonitor:

CPUID

Zone1 under Temperatures is negative and seems to correspond to that Processor Thermal Margin from the BIOS.

Thanks will check that out later.

Seems that DP45SG has C1E (Enhanced Halt State) always disabled All hardware info utilities shows that C1E is supported but disabled, (I have the latest BIOS 106). I'm not an overclocker and I would like to have C1E enabled, but there is no setting for C1E in BIOS (both normal and maintenance mode)...

Yep. I noticed this, too. Once, I THOUGHT it was on during a run of Intel's Processor ID Utility. But, I must have been mistaken since every run before or after that has shown it off. I'd suggest sending Intel's technical support an email and asking them about it:

Intel Corporation - Welcome to E-mail Support

EDIT: I double-checked the specifications for my processor:

Intel® Core™2 Duo Desktop Processor E8400 - SLB9J

and it says both Enhanced Intel Speedstep Technology (EIST) and Enhanced Halt State (C1E) are supposed to be supported.

I am pretty sure EIST uses C1E to work and I know EIST is working. Intel should probably take the C1E option out and leave EIST.

Very easy installation. Rock solid. Performance slightly above the DP965 (1FPS). Got a bit more headroom though. BIOS is good, although I have to use S1 mode for standby, as S3 will wake the computer - but not the monitor.

There is a new IDU for it - it's in beta however. I'll wait till later to install it.

The DP43TF was once advertised as a server board going for ~$1000.00 (per googling). This must be a mistake as I only paid ~$80.

Getting ~49FPS in FarCry2 with everything at "Very High" - I'm happy.

Thanks again for the link.

Merry Christmas to all.

Great! At least now you can run a new/old revision Wolfdale or Penyrn if you choose to later. This will boost performance quite a bit and run cooler.

Been waiting to get this card to make it perfect and I've found it. I will try to get the EVGA 896-P3-1257-AR. I was thinking I would have to get a GTX 285 to guarantee a 55nm GPU but it looks like the 55nm GTX 260s are going to be very discernable from the 65nm versions. Can't wait to get this card.

The only other thing I was interested in was CL7 memory but I am done buying memory. I will keep my CL9 and continue to enjoy running it at 1.5V. Since I am almost done with hardware I am looking at software. Going to get some cool games and an AV package. I am trying out MS Windows Live OneCare ATM (free 90-day trial). Anybody have a preference for a good anti-virii program?

This is from an old AnandTech article:

AnandTech: Intel's Pentium Extreme Edition 965: The Last of a Dying Breed

C1E - Enhanced Halt State

"Whenever the OS executes the halt instruction, the CPU enters what is known as the halt state. Architecturally, what's going on in a halt state is the clock signal is shut off to the CPU for some period of time. With no clock signal, none of the logic in the chip will do anything and thus power consumption is reduced. Performance is also significantly reduced; however, the halt instruction isn't usually called during application usage, so the performance aspects of the halt state aren't very important.

The problem with the halt state is that it does nothing to reduce voltage, only current draw by stopping clocks from going to the CPU. Since Power varies linearly with both current and voltage (P = I * V), you're effectively only addressing half of the problem. The Enhanced Halt State, as Intel calls it, does two things: it reduces the clock speed of the CPU by decreasing the clock multiplier down to its minimum value (on the EE 965 series, that's 14x, or 2.8GHz), then reducing the voltage. The clock speed is reduced and then the voltage is dropped, to maintain stability.

Intel insists that the enhanced halt state is a significantly lower power state than the conventional halt state, thanks to the reduction in voltage in addition to the reduction in clock speed. While the standard halt state causes a linear reduction in power, Intel's enhanced halt state causes an exponential decrease in power, potentially offering better power savings than the standard halt state. The real world impact obviously depends on how idle your system happens to be."

EIST:

"What EIST does is very similar to AMD's Cool'n'Quiet. It is demand based reduction in CPU clock speed and voltage. Using the same mechanism of adjusting clock speed and voltage, based on the application demand, the processor will dynamically increase/decrease its clock speed between its minimum clock and its normal operating frequency, as well as voltage, in order to optimize for power consumption.

Because of the way EIST (and AMD's Cool'n'Quiet) works, there's inherently a drop in performance. The idea is this: if you're performing a task that's not using 100% of the CPU, the CPU will operate at a slightly reduced frequency in order to conserve power. So, while some tasks will require that the system run at full speed, others will run at lower speeds. "

It looks like EIST senses CPU activity and then uses C1E to adjust accordingly. Obviously if you disable C1E then EIST will no longer work. That is why I think the option for C1E in BIOS is redundant and could probably be removed but I could be wrong.

I don't think so... As far as I understand C1E means reduced clock/voltage only when CPU is executing HALT instructions, i.e. when CPU has nothing to work on.
EIST allows software to dynamically control CPU speed/voltage during work and it is not related to HALT state. So C1E and EIST are different things, but they can be overlapped sometimes...
