Do you even have a ACPI driver in the device manager? If you do, it must be an old one.
That was 8 years ago.


ACPI / Power Management - Architecture and Driver Support

"A comprehensive approach to system configuration and device power control is built into Microsoft Windows operating systems, based on the ACPI system interface and other new bus and device specifications. Windows supports capabilities that can be exploited by drivers and applications to improve the user's computing experience"

Thanks. I will clean install WXP SP2 and retest. I think the problem is with the BIOS/CPU interface rather than ACPI. Speedstep works okay up to about 270MHz FSB, then remains locked at the higher voltage.

 

[DNyholm]

Well, I tried to enable speedstep and it looks like i am running into problems. The only thing i changed in BIOS is the set SpeedStep to [Enabled]. CPU-Z shows my voltages to fluctuate between 1.304 and 1.312 and my multiplier and clock speed do not change at all even when my processor is at 0%. I did notice that if i hit ALT-TAB to switch between programs, there is a program running called ASUS ACPI. Do I need to go into the POWER options and enable/disable anything (I am currently at the default settings). I tried to disable ACPI APIC support, but I could not boot windows. Currently it is set to enabled and ACPI 2.0 support is set as disabled.

Thanks for the help.

The Asus ACPI is buggy. You probably loaded it with a utility like PC Probe. The MS default ACPI works well. Anyway to find a restore point?

Clean installed WXP SP2 fixed the voltage reading issue. With SP2, the voltage AND core speed go up/down with load, as shown by CPUz. That's good. However, I did not notice any change in CPU core temperature during idling with Speedstep ON/OFF. A decrease of Vcore and CPU clock speed should have lowered the CPU core temperture. I use Speedfan, RmClock, and TAT to confirm that there is no change in CPU idling temperature with Speedstep ON/OFF.

Hooked up a calibrated Fluke ammeter on the AC input line to measure the actual current (in mA) during various states of operation. Power Options in Windows is set to NOTEBOOK mode. A Big Typhoon with one medium speed 120 x 38mm Panaflo serves as the CPU cooler. Switching to Minimal Power Management yields no change. ACPI is standard from Microsoft (SP1 or SP2). ACPI 2.0 enabled in BIOS.

Asus P5B Deluxe with 1101 BIOS, C2D E4300, EVGA 7100GS, and 2GB Kingston 800 ValueRam. System is stable with S&M max heat, 32M Super Pi 1.5 XS, Orthos, and TAT.

IDLE; 280MHz FSB; Vcore @ AUTO
-Speedstep ON....1.140Vcore...1680MHz core speed...1140mA current
-Speedstep OFF...1.304Vcore...2520MHz core speed...1220mA current

IDLE; 290MHz FSB; Vcore @ AUTO
-Speedstep ON....1.050Vcore...1740MHz core speed...1240mA current
-Speedstep OFF...1.330Vcore...2610MHz core speed...1240mA current

IDLE; 280MHz FSB; Vcore @ 1.475
-Speedstep ON....1.050Vcore...1680MHz core speed...1320mA current
-Speedstep OFF...1.448Vcore...2520MHz core speed...1320mA current

IDLE; 380MHz FSB; Vcore @ 1.475
-Speedstep ON....1.050Vcore...2280MHz core speed...1410mA current
-Speedstep OFF...1.448Vcore...3420MHz core speed...1410mA current

To verify that the ammeter is okay, I disconnected an 80mm fan and the current went down by about 10mA (1.2 watt).

Speedstep works in lowering the power, but only up to 280MHz FSB with Vcore in AUTO mode. At and above 290MHz, Speedfan still show a drop in voltage and core speed with Speedstep enabled, but the actual power consumption by the PC does not change (same current draw from the AC outlet). The test results were identical with WXP Pro SP1, even though Speedfan does not correctly report the voltage drop with Speedstep enabled.

I don't believe there is a problem with Windows (clean installed WXP Pro SP1 and SP2 with latest Intel drivers). Suspect the engineer at Asus is using BIOS 1101 to ignore the command to lower the voltage. You may think that you're saving electricity and reducing heat with Speedstep, but the BIOS locks Vcore above 280MHz FSB, and perhaps core speed. The actual current draw from the AC outlet remains the same as if Speedstep was disabled in BIOS and Windows!

I cannot downflash to an older BIOS in Windows. To accomplish this, I must use a bootable floppy. Course the 1M BIOS wouldn't fit on a bootable floppy.

I also tested the maximum power draw from the wall with Orthos and TAT @ 100% load for 10 minutes.

FULL LOAD; 380MHz FSB; Vcore @ 1.475; 3420MHz Core Speed
-Orthos...2320mA (~278 watts)
-TAT.......2600mA (~312 watts)

I didn't realize that TAT would draw that much power from the wall. The idle load went from 169 watts at idle to 312 watts at 100% TAT load! You'll need a very powerful CPU cooler if you want to push these latest C2D chips to the max. The technology permits a very high core speed with additional voltage, but the current and heat generated will also explode, BIG TIME. I wouldn't push higher than 1.375Vcore with the stock CPU cooler.

This chip is capable of 3.5 to 3.6GHz on air, but only with a better CPU cooler. I'm already pushing 65C Orthos with 81F ambient (30C no load). Yes, the surfaces are lapped with 2000 paper.

I am having a strange issue with my hard drive.

I have
p5b deluxe, E6400 at 3.3ghz(8x412), 2gd crucual 6400-c4, 7900gt OC, and a Samsung HD321KJ drive. The drive is sata2, connected to Sata port 1.. I have a sata dvd on sata port 4(black connector)

The machine seems sluggish and a defrag tood days. My drive benchmarks are pathetic.. I mean pathetic. HDTUNE says I maxout in the single digits. I noticed that the drive is UDMA7, but running at udma5(at100). Any ideas why that would be? I cannot find anything in device manager. Is there a problem with the sata driver?

many thanks,
Ken

 

[SerpentRoyal]

Check the performance of the DVD ROM. If okay, then remove the DVD ROM and move the HDD to port 4. Still have problem? Can you clean install windows on a blank HDD? That's the easiest way to isolate software issue.

Hmm, in that case, i don't think I really need to worry about SpeedStep as I am running 39 idle 50 load and when I play my games, I am about 45 or so. It is just annoying as my fan ramps up in speed at 43 or so and it kinda gets loud. I guess i could always adjust with speedfan, but i'd rather not get into messing with that.

On another note, has anyone had any troubles getting past 401 FSB? If I go anywhere past that, I can't run stable no matter what I set my vcore to (currently at 1.35v in Bios, 1.30 running). I'd like to be able to run at 410-425 FSB since i think I have the cooling, but nothing seems to work.

 

[Rafael]

Linking the pictures

TAT
CPUZ
CPUZ 6x
CPUZ Memory

That is very odd, because my vcore won't go down when my system is running at 6x.
Unless I leave it in AUTO.

Dnyholm,

You mean by unstable, Orthos errors? Or BSODs?
Because I can run my system 500 Mhz x 7 without BSODs, lockups, etc. But I always get random errors in Orthos. But it is stable in Windows, I can play games, leave the system running for several days.
What I did not try yet is raise all the way up the NB voltage. And I think that is why I get random errors, but no BSODs, lockups, etc.
I start to get lockups and BSODs when I get over 3600 Mhz or when I have tight timing without the right voltage.
I can put my system to boot, get in to windows and run 1 round of SuperPI running @ 4 Ghz. But I was not able to save the screen. Maybe up the Vcore would do it, but I did not feel comfortable to put the vcore over 1.55.
I might play around more now that is getting colder here, and when I get on vacations from work.
Tell you the truth I did not see the benefits of pushing the system to higher FSBs. The P5B Deluxe (I don't know about the other models) has the problem of the NB strap, if you set your FSB up to 400 Mhz, you stay in the 1066 Mhz strap, and you pass the 401 Mhz you get the 1333 Mhz strap. And your performance starts to degrade, so you loose the performance.
And for the best performance, without much effort, is to run the system in assync mode (i.e. FSB 400 Mhz and memory 500 Mhz)
I have a comparison with different FSBs and timings in SuperPI, but I need to test a few more FSB speeds to get the results that I want.
If you are interested let me know and I will post here.

[SerpentRoyal]

Did you enabled ACPI 2.0 in BIOS? The voltage drop may appear in CPUz, but there is no actual drop in current at the AC wall outlet. I measured the AC current at the wall with an ammeter, and there is no change in current draw when the voltage drop.

Has anyone installed a normal IDE controller card into the normal P5B-E board?

Can't get 800MHz RAM to run at rated speed

Sorry, but i'm a bit of noob here.

I'm having trouble getting my 2G's of Kingston 800MHZ Value Ram to run at its rated speed, and was

wondering if someone here might be able to point me in the right direction.

I have
Asus P5B Deluxe motherboard,
conroe E6600 CPU,
and this RAM kit:
Kingston ValueRAM 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit

Desktop Memory Model KVR800D2N5K2/2G - OEM

which i believe is listed as being qualified to work with my motherboard.

When i first power up the machine, the BIOS complains "oveclock failed!" and prompts me to load its

default settings. I do, the machine restarts and then fails to POST. Only by removing the battery

and jumper am i able to restart and get back inot the BIOS.

After tinkering around in the BIOS for a while and restarting a few times I was finally able to get

the machine to sart up by changing the DDR2 RAM speed (Jumper Free page of Advanced BIOS settings)

from 'Auto' to 667MHZ: all other settings are default, nothing overclocked. Since then i have been

able to install WIndows XP and have had the machine up and running stable for a couple of weeks

now.

I called Kingston tech support, they talked me few a things that did no good, RMA'd the RAM, which

i swapped out and....same thing! What gives?

Is tweaking the RAM voltage up a bit from its default 1.8V worth a try, or do I risk frying it?

Cheers,

Jonathon

 

[Rafael]

Jonathon,

First of all, welcome to AT Forums!

Let's go in parts.
Do you know if you are trying to run your memory 1:1, FSB and memory at the same speed?
Probably what is happening is that you are trying to set the memory to 400 Mhz in the FSB, and with a E6600 you will NOT be able to achieve this.
Try to run your system assynchronous, leave the FSB at default (266 Mhz) and try to run your memory at PC26400.

That is my guess.
Try that and let us know if it worked.

Rafael

 

[Jonathon]

Rafael, thank you very much for your reply.

> Do you know if you are trying to run your memory 1:1, FSB and memory at the same speed?

I'm afraid i don't. How would i tell? I don't see an 'FSB:RAM ratio' option anywhere in the BIOS (perhaps its called something else?).

The only setting i'm aware of that mentions RAM speed provides as possible choices {<3 smaller values>, 667Mhz, 800Mhz, <two bigger numbers, like 1096?>, Auto}. Is this setting in fact implicitly controlling the ratio you describe?

When set to auto (oh, and another setting somewhere to do with SPD detection, also enabled by default), the motherboard appears to think I'm trying to overclock the RAM for some reason. Same thing when I switch RAM speed from Auto to 800Mhz. The lower value of 667Mhz allowed me to POST ok though and boot into Windows. Like this, I am able to run CPU-z, which reports the CPU mutiplier as x9 (although it drops to x6 when idling: something to do with Speed Stepping, NIOS, or Orverclocking AI support?), the FSB hovers around 266Mhz, and the CPU speed as 2.4GHz. Is that any help?

Ummm, what does 'assynchronous' mean here, and what BIOS settings changes do i make to do as you suggest?

Many thanks,

Jonathon

 

[Rafael]

Jonathon,

In the BIOS where you are setting the memory speed, you got CPU FREQUENCY and DRAM FREQUENCY.
If you set the CPU FREQUENCY to 400 and the DRAM FREQUENCY to DDR2-800 Mhz you will be running synched, 1:1. If you set the CPU FREQUENCY to 266 and the DRAM FREQUENCY to DDR2-800 you will be running assynch. Because you will have your CPU Bus (FSB) at 266 Mhz and the memory running at 800 Mhz.
If you already have that, and no go.
Try to change the timings, set it manually, change to SPD to Disabled and set it manually, and put the values as your memory spec says.

Hi there guys, the search tool wasn't working so I greatly apologize if this same question was asked before...

I recently got my quad core system (woot), most everything is running well. I was having issues with my PCI Express so I tried reformatting and fooling around with the BIOS. I Finally fixed it and got my 3DMark scores at the level it should be performing... but anyways that's not the point of my problem. I thought my HD was underperforming (WD Raptor 150) and was causing my framerates to plummet, and I also thought because I did not install the ICH8R driver at Vista setup the HD was underperforming, but it actually was fine and forgot the drive is NOT SATAII.

So, ONLY AFTER installing the ICH8R driver I notice my main drive (the raptor) randomly stalls. It could be light or heavy load on the main drive to trigger this. My mouse moves and windows can be clicked here and there, but stalls anything loading off the Raptor drive for approximately 30 seconds such as music, games, IE, MS Word etc. Not what I expected from a high end system like mine. So i reformatted a few times and still the issue is there. I've tried using the Intel Matrix Storage utility to check evrything out, and all is fine. I found a fix on intel's site by deleting a regkey that conflicts with the SATA controller. http://www.intel.com/support/c.../imsm/sb/CS-025783.htm. After deleting the regkey, the problem has reduced but is still is quite apparent. I have my hard drives set in ACHI and setup windows vista that way, I am also an old member of driverheaven and some members found issues with the Yukon Marvell controller causing performance issues. in this thread I created: http://www.driverheaven.net/ha...issues-raptor-x-2.html

So I don't know if the ICH8R driver is loaded on all my hard drives, even after I reformatted my master which is my raptor. Or if something else is causing these stupid stalls. What might I be able to do to solve this issue?

My basic setup is as follows

Intel Core 2 Quad Q6600
Asus P5B Deluxe
BFG 8800GTS OC 640MB
2GB OCZ Platinum 4-4-4 DDR800
WD Raptor 150GB
WD Caviar 250GB
Seagate Baracuda 250GB
2x LiteOn 20x DVDRW (SATA)
SB X-Fi
TV Wonder Elite
Vista Ultimate

All help is appreciated

1. Update to 1101 BIOS (latest).
2. Reset CMOS.
3. Go into Advanced/Jumperfree Configuration/AI Tuning and change DRAM Frequency to 533.
4. Go into Advanced/Chipset/Northbridge Configuration/Configure DRAM Timing by SPD and change from ENABLED to DISABLED.
5. Change timing to 5-5-5-15.
6. Hit F10 to save and exit.

Reboot back to BIOS and raise FSB to increase CPU core speed. The RAM should run at 1:1 ratio north of 370MHz RAM speed. Use CPUz to check RAM speed.

I made the mistake of loading the ASUS Ai Suite. It changes the APCI driver that I believe does not function fully in VISTA. Even Though, It is a Vista version. I un-installed it and it will not fully un-install. I attempted a restore point. But any thing with that installation or before gives me a Blue screen. Than I need to schedule a an error checking on that drive to clean up the mess.

Dam ASUS, I don't like the Vista support on this board. The sound driver does not even have a left and right speaker control. I looked at the P5B Vista version and they have the same poor sound driver. I just want my MS APCI driver back and get the ASUS APCI Center out of my task manager.

I have Vista 64 and it runs great. I did have the hard drive slowdowns or un responsiveness with the Vista 32 Bit. But, since I went with 64 bit my raid 0 speed is fantastic. It is very stable OS. As long as you don't use all the ASUS drivers and utilities.

The only reason I use the ASUS sound driver is for the SoundMax mic. It did not work with the MS sound driver that had many more features.

I uninstalled the ASUS Ai Suite w/ ASUS ACPI. But look, it is still there!

Yes it does support the new CPUs with 1333 Mhz bus, since BIOS 1004. And no words on Penryn yet!

What SATA port you got your HD hooked to?

 

[BigBrownPimpsta]

guess the first sata port... on the intel controller. Should I try the Jmicron controller?
