WinXP BSOD's and memtest errors! (KR7A-133)

[f300]

System:

AMD AlthonXP 1800+
Abit KR7A-133 (non-raid)
Crucial 256Mb PC2100 unbuffered non-ECC
Leadtek Winfast Geforce2 Pro (Det 21.83)
Maxtor DiamondMax Plus D740X 60Gb
Creative SBLive
Happuage WinTV
Realtek RTL8029(AS) Nic
Realtek RTL8139 Nic
300w power supply
WinXP Pro installed on D:
Windows98SE installed on C:

The CPU, mobo and memory are new. Everything else has been working fine for a while in an Abit KG7-Lite with T'Bird 1.4.


Since installing the new mobo/cpu/memory and clean installing WinXP, on boot about ten seconds after the desktop has appeared i get a BSOD with one of the following errors:


DRIVER_IRQL_NOT_LESS_OR_EQUAL
USBUHCI.SYS F9D0D6B2 base at F9D0A000

OR

IRQL_NOT_LESS_OR_EQUAL


It only happens on cold boot and when it's been off a while. Normally i've just rebooted and then it's been fine. This morning i got the first error, rebooted, then just after the OS menu i got "unmountable boot volume". So i used the recovery console to do a chkdsk on D: which fixed the problem. It then booted fine.

Also, when I first got the new mobo/memory/cpu installed i ran Memtest. It gets through all the tests with no errors, apart from Test 5. At first it gave about 300 errors each pass, but now it varies between 3000 and 20000. The memory is set to 133Mhz with the slowest timings, fast command decode off. If i use more aggressive timings i get many more errors, upto 200000. When i put the memory bus to 100Mhz i only get 70 errors. I've tried two sticks of Crucial PC2100 seperately, both producing the same errors in memtest but neither produce any errors when used in a KG7-Lite.

Apart from the bootup errors, everything seems ok. Any idea what's causing the bootup problems (and how do i fix them)? Are they related to the memory errors, and is memtest reliable? Every other test i've tried has been fine.

Thanks!

Try restoring defaults or flashing. Try other modules. Try other RAM testing software.

 

[f300]

Set fail-safe defaults and it made no difference to memtest. Can't check the Windows prob until comp has been off a while as it only happens from cold boot. I've already tried different memory utils, (burn-in test, sandra benchmark, and a couple of others) and they give no errors, but they don't appear to do any "block move" tests, which is what memtest fails on (test 5). Unfortunately I have no other memory modules to test with, but using a different Crucial PC2100 stick made no difference to the number of errors. The mobo came with the latest bios available.

I've been getting EXACTLY the same problems!

XP1800
Crucial 2100 DDR
KR7A-133 no-raid

I get the same boot up errors and have had the unmountable boot volume error also. I also get lots of random BSOD with irq not equal or PFN_LIST_CORRUPT errors. I also ran memtest and get loads of errors, I tried Docmemory which gave an error but only once. I just today ordered another stick of Crucial 2100, I wish I hadn't bothered now! ( Typically out of 300 PC's at work we don't have any that use DDR typical!

hey guys

i currently use a P4 rig (you can see the specs on the link below), but I also had the exact same problem. After days and days of reinstalls and debugging, I finally fixed the problem by installing all the mobo drivers that came with the mobo. For some reason, the native xp drivers were causing all sorts of problems. I had to install the intel .inf's for the i850 chipset, the hpt370 raid driver, and the bus mastering drivers. give it a try and see if it helps.

 

[athlonoc1]

Any of you guys got a USB modem, and is it for dial-up or DSL.

Let me know what you have, I may have some answers.

 

[f300]

kjhoskin - I also got the PFN_LIST_CORRUPT for the first time this morning. Are the errors you get with memtest only on Test 5 and/or Test 8? What's the rest of your system? (pci cards, graphics card, power supply?)

GiGoLo - I've tried the via 4in1 drivers that WinXP loads, and also the latest version (1.437a) and it made no difference. I've tried George's PCI latency patch which also doesn't help.

athlonoc1 - No USB modem, just a cable modem plugged into a Realtek RTL8029(AS) Nic. I've got a USB Epson printer, a USB HP scanner, a USB intellimouse and a USB hub built into my Ilyama VMpro451 monitor though.

 

[NogginBoink]

A PFN_LIST_CORRUPT bugcheck is almost certainly bad RAM.

If you're getting ANY errors doing a memory test, THROW THE RAM IN THE TRASH!

Your acceptable limit should be zero errors. Zero. Any more is not acceptable.

 

[f300]

But both the sticks of Crucial PC2100 I tried do not give errors in another mobo (Abit KG7). So is it the KR7a board that is faulty, or is the RAM not good enough?

 

[kjhoskin]

rest of my system:

300W PSU
Sonicfury Soundcard
Videologic Vivid 32mb KYRO graphic card
8Gb Quantum fireball HDD
27Gb Quantum fireball HDD

yep I have a USB modem but I had errors installing XP without this installed so I don't think its the culprit. Its looking like the Crucial memory is the little tinker causing the grief! I've ordered 256Mb of Samsung DDR today which should be here in a day or two I'll give that a go when it arrives. I'll get back to you on the memtest as I'll need to run it again. I'll post the answer tomorrow.

cheers

Let me know if the Samsung memory fixes the problem!

 

[bevancoleman]

Some idea to try,

* Do not overclock (You didn't say that you where, but if you are)

* If you have two sticks try leaving a free slot between them (ie, put ram into slot 1 and 3).

* reset bios using jumper on board (turn off first ), them reset to default in bios. Don't tinker with the settings

* The Mainboard might be deap



MemTest86 should give NO errors, even 1 error will corrupt your system and cause data loss and crashes. The MemTest page also has some info on debugging the problems.

 

[bevancoleman]

dup ...

 

[kjhoskin]

No I'm not overclocking its a bit of a pain to do with the AMD XP so I'm not bothering.

I ran memtest again lastnight and it does indeed fail on test 5 quite near the end of test 5 in fact

 

[f300]

I'm not overclocking either.

I've just tried the ram in a different slot and it made no difference. Also, I took everything out of the system, leaving the memory, floppy, and an old 1Mb PCI graphics card and that made no difference either. So that rules out the PSU and any cards causing the problem.

it's possable you've got a board that disn't like critical memmory (or at least the sticks you have), got any generic sticks?


It is also posable that the board is faulty.

 

[kjhoskin]

my new memory arrived at work today I'll try and give it a go tonight and see what happens

 

[kjhoskin]

I got back very late lastnight from a Travis concert but I managed to fit and test the Samsung 2100DDR memory and it worked fine NO ERRORS at all with memtest. So it looks like a problem with Crucial 2100 DDR and the KR7A MB

 

[nealh]

try upping the voltage on the ram you memory setting may require more voltage

 

[f300]

nealh - Tried that, made it worse.


kjhoskin - I've e-mailed Crucial about it. Where did you get the Samsung DDR? Glad it's fixed!

 

[kjhoskin]

hiya

Well I don't know where you are but I'm in the UK so I got the memory from www.Simply.co.uk I've only run memtest as I didn't have time to do anything else lastnight but I'll give the PC a good try this weekend to check stability.

cheers

Kerry

 

[nealh]

f300 that is interesting that more voltage lead to more problems..sounds as if crucial needs to replce the ram for you
