I'm thinking the 6x VID from SpeedStep is 1.15, so you are also better off with manual undervolting across all multipliers. Tonight I plan to install RMClock v2.35 which has Wolfdale/Yorkfield support. I couldn't set a P-state pair below 6x / 1.15v with version 2.30.

Good catch, see this: viewtopic.php?t=47470&highlight=anandtech

I personally prefer Steam over discs primarily due to portability and protection. In my houshold with 3 gamers, discs get torn up. With Steam we now install a game on all computers and play on any one (at a time, of course) and there's no disc to protect. Also the kids can login to the Steam account...

Your MB kicked butt in low power consumption in this review http://www.anandtech.com/cpuchipsets/sh ... i=3288&p=1.

Does this mean that if I take a 65W processor like an E8400 and clock it at half its rated speed and also undervolt it I can expect mobile-like power usage? Right now I am kicking myself for spending way too much on my home server mobile-on-desktop setup (see sig). I think these new 45nm will kill ...

What clock speed are you running it at? Stock speed for the Q9450 is 2.66GHz (8x333) and under Prime95 it's pegged at 8x and 115 watts. At idle it drops to 6x333 and the idle system power drops to 77 watts with 0.99375 VID. When manually set, voltage stays at 0.99375 VID under all multipliers. The ...

Voltage is the key, not only for OC'd power use but at stock speeds as well. I found the Q9450 to be a tremendous undervolter. At Prime95 4-core load with 1.225 VID, my system pulls 153 watts and with 0.99375 VID, it pulls 115 watts, both stable. That's a 38 watt drop from the cpu alone.

How many fans/fan headers/fan sensors on that board can be read by a utility like Hmonitor or Speedfan? Funny you should ask because right now I am trying to figure how to get Speedfan to make sense. It's monitoring two fans but giving me crazy speeds in the hundreds of thousands rpm. The MB has 2 ...

With the Q9450 Coretemp uses 105 as Tjunction while Realtemp uses 95, so Coretemp reports 10C higher temps. There seems to be a consensus forming that Realtemp and 95C are correct and that's what I think based on waking up the system from C3 (edit: S3) and quickly checking idle temp. If Tj is 95C th...

The OP's questions on cpu and MB are dependent on WHS usage, especially wrt the handling of media files by both server and client. From what I understand, if you are serving media files to a PC, you dont need much WHS horsepower because the client PC can handle the on-the-fly-transcoding. If you are...

Undervolting an E2000 for WHS is a good idea, and I just found out how good the Gigabyte P35 boards are at undervolting with a DS3L and a Q9450 at less than 1.0v VID. At $90 for the DS3L (rev2) and an inexpensive cpu, you can build a WHS machine on the cheap and put cash into hdd capacity. A couple ...

If the kontron supports EIST speed step, then you really don't need to undervolt. The T5500 in my WHS machine spends most of it life at 6x and 0.95v (the lowest "stock" speed step setting). For WHS you'll want a 64-bit capable cpu for compatibility with WHS upgrade plans. I believe the cheapest mobi...

jerryk,
Can you post the cpu voltage in BIOS or with cpu-z? I'm curious about the Q9300 stock settings.

I confirmed that both SpeedStep and RMClock can only change the multiplier once voltage is set manually in BIOS on the DS3L. And since my lowest stable voltage is lower than the SpeedStep voltage at all multipliers (6x 7x and 8x), that's a good thing.

I was surprised myself, especially since the Q9450 defaulted to 1.2375v or thereabouts out of the box. Here's my setup experience: viewtopic.php?t=47335&highlight=

According to the bios settings the default Vcore voltage is 1.225 Volt which seems rather high, maybe I got a bad sample? My Q9450 defaulted to a high VID, and I thought the same. However it undervolts big time: Prime95 stable at 0.99375 VID (0.960 Vcore idle, 0.944 Vcore load). So don't worry too ...

what is the lowest power CPU to put in such a system? Should I underclock? Does an E2160 or E4500 make sense - what is the power consumption for these CPUs? If not that then what? Does an E8200 make more sense - the processor speed is overkill but will the lower power consumption help? I am running...

A single multi-drive RAID array which contains both the WHS system and client data files is not affected because it looks like a single drive to WHS. Data on multiple individual drives are only affected by client applications that attempt to write to a file on the server that is concurrently being w...

Q9450 Yorkfield 2.66GHz (333x8)

Prime95 stable for 11-1/2 hours at 0.99375 VID (0.960 Vcore idle, 0.944 Vcore load)

Try RMClock for software throttling. It achieves both multiplier and VID adjustments based on demand amongst several other controls.

The system was Prime95 stable for 11 1/2 hours today at 0.99375 VID (0.960 Vcore idle, 0.944 Vcore load), so I'll call that the basement. I didn't have time tonight to run a full suite of VID's with the killawatt, but I did take the end points: 1.225 VID pulls 87 watts idle and 153 watts load and 0....

I have not calibrated Realtemp...but that doesnt effect load temps..and I'm looking at delta from Tjunction anyway. I have a killawatt meter...will check power draw across a range of VID tonight and post results.

It ran Prime95 stable for 2 hours at VID 1.000 and I ended the test to approach the limit from the other direction. With VID set to 0.975 Core3 generated a P95 error after 2 minutes. Reset VID to 0.98125 (0.928 Vcore load) and Core1 generated a P95 error after 20 minutes. Reset VID to 0.9875 (0.944 ...

Today 12 3/4 hours at 1.05 VID no errors. On my third step down from there I am currently Prime95 testing at 1.000 VID 0.960 Vcore idle (6x) and 0.944 load (8x). Prior 2 steps tested 30min Prime95. Load temps now settling at 53C to Tj.
