Freezing

Hello you all. This is one of my rare problem. I observed when I load an empty mod patch from any one of the Modular my PC would crash. When I restart I cannot open up the Scope software. I have to reboot several times to use the PC too. I have Scope 4, Win 2K, Asus P4B 533 Mobo, 768 MB DDR 266, P4 2.53 processor, an Nvidia video card and two Luna 11

There seems to be a major problem with SFP 4 and HT processors (Intel 875 chipset). SFP4 frequently locks up the machine completely and you need to reset the PC. If you can get ‘Windows Task Manager’ started (sometimes you can but often the machine is just totally locked up and you cant start WTM) you will notice sometimes that 50% CPU loading is constant. The solution I found is to change the driver for your ACPI (XP = Control Panel, System, Device Manager, Hardware, Computer, ACPI). Select Properties and choose to 'Update Driver' 'Install from a specific location'. Choose the "dont search I will choose" option and select the standard ACPI option, NOT the 'dual' or 'multi processor' ACPI option. Reboot and SFP will work perfectly.

I don't have HT in my system but I am experiencing exactly what you described above. It only happens when I load the empty Modules. Maybe I should go back to 3.1c. It was very stable.

Hi,
I had trouble with freezing too. I think Sean_Middleton meant to write, "choose Standard PC" instead of choose Standard ACPI.
Maybe my post to Jngaelin that I just made, will help. Same forum.

virtualstudio also had a freezing problem. I had that problem with my Korg Oasys until I disabled USB in bios. In Creamware though, I got the impression my problem was a disagreement with the number of midi drivers in my projects and the number of them in the Windows Device Manager's Scope settings tab.

I am running Scope 4 on Windows 2003 Server, in HT mode with 4 (four) processors

(2 real ones), awesomely...

Although, I disabled the ACPI in BIOS before I installed Windows. Maybe, you have to disable the ACPI in BIOS if you switch to Standard PC mode.

Bingo - don't you mean disable the APIC in BIOS ?

BingoTheClowno · Post by **BingoTheClowno** » Wed Jun 02, 2004 12:21 pm

What I wanted to say is that, one has to make sure if one switches to a Standard PC mode in the Device Manager, maybe one should also disable the ACPI (Advanced Configuration and Power Interface) in the BIOS also, just to avoid any possible conflicts.

Also, if one disables the ACPI in BIOS but leaves the setting in Device Manager to ACPI Uniprocessor (or other ACPI setting), maybe that is also going to create problems. I don't know for sure, but it could. Or does Windows detect the change?

Well the only solution I have found that cures my glitch /freeze problems is to do the following: -

Install windows in ACPI mode (HT disabled).

Tweak and install all my programs

Go into the deive manager and switch the computer to Standard PC mode

Re-boot and install my drivers again

Re-boot and turn off ACPI in the bios

At the moment it seems to be running without problem (touch wood).

Talk about a nightmare or what

Plato · Post by **Plato** » Wed Jun 02, 2004 2:17 pm

Scott, why not just install in Standard PC in the first place......that seems an incredibly long-winded approach, and probably won't be helping the stability of your system.
Bingo - what I meant was, I thought you could only deal with the APIC in the BIOS (not ACPI) ie the Interrupt Controller....correct me if I'm wrong

BingoTheClowno · Post by **BingoTheClowno** » Wed Jun 02, 2004 2:28 pm

Sorry Plato,

, I kept thinking ACPI and thought maybe you made a mistake with the abreviation. APIC (Advanced Programmable Interrupt Controller) is only available in BIOS.

Majestik, that procedure sounds fishy. If you change the PC mode in Device Manager, make sure you disable it in BIOS after the first reboot.

No sweat, Bingo

Scott - the way to do a fresh install in Standard PC mode (from pcaudiolabs.com):

When you see the installation tell you to
press F6(Third Party SCSI or RAID Drivers)
press F5 instead. You will see Press F2 for Automated System Recovery(DONT press F2)
Right after that you will see a list
Press the UP arrow key to highlight Standard PC
Hit Enter..
Hit Enter to Continue
Hit F8 saying you agree.
Now, if this is an existing OS of say Win2k or a previous install of XP you will see options for
Esc=Don't Repair; R=Repair F3 to Quit
Well, we're doing a fresh install so we want to hit Esc for Dont Repair
Now, you'll see your drives and partitions here..
If you have Two "physical" drives it will show you these drives as C and D
Highlite C Drive
If you had an existing Install from any other OS press D for Delete Partition.
Press Enter to Continue
Press L for Delete

Now, we're back at the drive selection screen again and this time we see Unpartioned space..
We're ready to create a partition.

Typically you want to the OS drive to be as small as possible for drive reading purposes.
Reccomended OS and Application drive should be around 12GB tops.
If you have a 20GB drive partition it into two parts..
the first part being 10,000MB and the remaining to the
Second partition(comes to around 9500MB)...Which can be used for extra storage

BingoTheClowno · Post by **BingoTheClowno** » Wed Jun 02, 2004 2:45 pm

I would recomend before installing and going through the above procedure, disabling the ACPI in BIOS. APIC should be left enabled.

With HT processors WIn XP gives 4 options to do with ACPI. Standard PC, ACPI (standard), Multiprocessor ACPI and one other which I can't remember (I'm at the office on a none HT Machine). Of course you wont get the Multiprocessor ACPI option if you dont have a HT CPU+MB machine.

Hey Sean_Middleton,

Thanks for posting your reply. I'm not familiar with hyperthreading at all, thought you were making a booboo.

Doesn't work I am afraid. I tried installing the computer as a standard PC from fresh but I got the same problems as if it was installed as an ACPI.

Don't ask me why it did that because I couldn't tell you.

hmm, strange.....what's your system, Scott ?

yo !

i have pentium4 2.8HT with intel mobo 865PERL, acpi installed (default),WinXP sp1a with SFP4.0 running and so far i don't see any problems....

Something I haven't seen mentioned, the latest p4 models have FAR better HT implementations than the first few chips to have it enabled. I should know because my Prestonia-core Xeons had HT before it was even enabled in the 'consumer' p4 line and the implementation in my chips gives a 10-15% DROP in performance across the lines. This is even with apps that see an increase in performance with a modern p4 core. So if you're experiencing HT problems you may wish to check & see what revision your p4 core is.
