View Full Version : recent loss of stability: BSOD on win2k boot
I've been running this cpu (see sig) at 1.87vcore for about a year and it's behaved nicely.
Recently, it's been giving me bluescreens when booting at 933, and I've had to drop it back down to 700 (where it behaves again). This has been happening off and on since I changed to win2k (from 98se).
The alpha has been keeping it nice and cool (21C idle, 24 load now....34 in summer) and I haven't changed anything else (memory, bios,psu, peripherals).
The funny thing is that it works great under load (CS, RTCW, Sandra) at 933; the problem is only on cold boots or restarts. It will go in and out of stand by without a problem.
I have heard that the NT kernel OS's are more sensitive to instability, and that is why I'm seeing this now. Have I been running too much voltage over time and am seeing the results of electromigration? I've tried dropping memory timings to no avail, but my memory is high quality ( I even tried pulling one stick, in case the two brands were not playing nice together).
I have SP2, all the MS updates, and the current 4in1's (including the pci latency patch).
Anything I'm not thinking of?
What is the error specified in the BSOD?
Could be sometimes Win2K just corrupts itself since the NT Kernal aren't so overclocking friendly.
They're registry errors...can't load corrupt/absent hive file in
systemroot/sys32/config/software
Sometimes I get 'config initialization failed'
I may try tweaking the voltage up and down, and checking for proper heatsink/slotket mounting, in case something shifted when moving the case around.
Can you get into Windows at default speeds?
If you can get the bootdisks and then go back to full throttle in this case 933 and use the repair option.
Yeah, default (700) works fine.
I tried the repair (at 700), using an EBD.
I can't get through a setup-load at 933.
Think I saw something similar to this in another thread the other day. Might have been you, but anyway, I had pointed out that those modded Promise RAID cards have been known to degrade before and begin corrupting files.
May be something else but worth looking into.
did you install 2000 with your CPU overclocked? Its not good to install your OS with your CPU overclocked even if you think its rock stable.
Yeah the install was overclocked (since I thought it was stable with 98se.
is the PSU aging, if the setup was working well before?
I had similar (not exact, as the windows2000/me boot up okay, but with an error message saying the registry files were corrupted, need to reboot, then the next time it's usually okay) problem in the cold-boot situation randomly (ie turning on the machine in the morning) when I pushed the FSB around 140 even the Vcore were upped to 2.0v.
The chipsets of my MB are same as yours. I am now using 1.8v Vcore. Voltage are set by jumper. Is it possible the cold-boot problem in i-815 also happened to 694X, ie, POST at default voltage? Or it should only happen to MB with Vcore selected by BIOS? How about yours? Will the CuMine wire-trick help?

Its probably best to format and reinstall at stock speed then overclock after the OS is completely setup stable
I can set Vcore easily on the Abit slotket III (max is over 2.5 I think!) , so no need for a wire trick. It is set to 1.85 on the slotket and reads 1.87 in bios and MBM.
The big question I haven't figured out yet, is why the BSOD only on bootup if it was stable under heavy gaming??
The PSU is less than a year old...it's a 400watt Leadman Powmax. I guess it wouldn't hurt to throw an old psu in to check.
That was me with the Promise problem, but I think I tracked that down (sort of) since I am having no problems whatsoever at 700 Mhz. I guess I could pull out my array and load 2k onto an old drive (using the ongoard IDE) and see if it boots at 933.
hmm. you know last month i was running at 1.75v and then i took my computer home because my brother wanted to see it and it wouldnt even boot until i boosted it to 1.85v.
anyway i have to agree that windows 2k doesnt like a lot of things. i usually get the kernal not founds and corrupt registry if i oc too far. the blue screen that pops up after the windows 2k white loading screen is done.
this is a dumb and tedious method and so is a last resort:
start only with video card and without raid card and see whether there is still BSOD if yes then replace one by one the RAM (also try slowest timing 333/68), PSU, CPU, video card with borrowed items until BSOD problems do not recur, bit by bit you'll narrow down to the bottleneck
can also find the S-SPEC (like SLY45) of your 700E and check against overclockers.com database and see whether that may be a good or bad one
It's unlikely to be the peripherals (raid, voodoo, sound) since PCI is in spec at either speed (my board has a 1/4 divider).
The memory is PC133 and PC150 so it should cut it at 133, even with aggressive timing. I did try taking a stick out (in case the two brands didn't work together)...no luck.
I think it's my memory. I have 2 brands... a 128 stick of kingston PC150 and a 256 of generic PC133. They aren't playing nicely together. I pulled the 256...boots fine at 933. I put both in and set the mem clock to 100, and it boots fine.
I may have to sacrifice my memory timings or cas2 to run both sticks. Damn.
are you allowing your MB to adopt the SPD (preset memory timing) of the RAM modules? as they are of different brand and spec the timing (like 222/46) will be different and not compatible to each other at high FSB
You can disable MB reading from the SPD and use Bios and Wpcrset to standardise the RAM timing. Please check your PC-133 is CL2 sustainable or not. Also even your PC-155 may not be PC-133 CL2 sustainable.
I changed the timing for the PC133 stick down from 'turbo' to 'normal' and it works fine now.
The PC150 stick is still on 'turbo' and CL for both is 2.
u mean your Bios allows you to select "Turbo" or "Normal" for each RAM module?:eek:
Yup! I think there are 5 or 6 settings for each individual bank. There are some advantages to using Darth Via chipsets!
Interleave is set for all of them (I'm using 4 way).
