Ive just bought some new memory (TWIN2X4096-8500C5C G), the new memory doesnt seem to work unless I only add one stick, and even with that I get blue screen errors.

So from reading a few pages on teh internet I put my old memory back in, and ran windows driver verifier. Upon restarting I got and keep getting teh following BSOD.

IO SYSTEM VERIFICATION ERROR in wmiacpi.sys (WDM driver error 20e)

If the system ran fine...before you added RAM...then you need to see if the new RAM (by itself)...works.

The new RAM may not be compatible with your old RAM, in which case the system will run fine with one or the other...but not both.

The Driver Verifier tool is tricky to use, I would disregard that effort...for the moment.

Remove your old RAM...put the new RAM in...see if the system works properly.

So I removed the old 2gb module and replaced it with one of the new 2gb modules.

I let the computer boot normally and it came up with teh following blue screen:

IO SYSTEM VERIFICATION ERROR in wmiacpi.sys (WDM DRIVER ERROR 20e)
[wmiacpi.sys+152f at B7C1452F]

So then I rembooted in 'Safe Mode with Networking'

I got the following BSOD:

STOP:C000021a {Fatal System Error}

The Session Manager Initialization system process terminated unexpectedly with a status of 0xc000026c (0x00000000, 0x00000000)


I then put the old memory in and booted normally again, got this bsod:

IO SYSTEM VERIFICATION ERROR in wmiacpi.sys (WDM DRIVER ERROR 20e)
[wmiacpi.sys+152f at B7C5452F]

So I am posting this message in safe mode, please help :S

I'm not sure you read the directions for using Driver Verifier.

Once you engage it, it will continuously give you a BSOD...you have to disengage it to get the system to boot normally. I've used it once or twice and I'm sure I made the same mistake regarding disengagement.

To disable the Driver Verifier, start your system in Safe Mode, which will bypass most device drivers, thus preventing Driver Verifier from going into action.

Once in Safe mode click Start|Run, type

verifier /reset

in the Open box and click OK. This will disable Driver Verifier and allow the system to boot normally, you can then replace/update the offending device driver.

Troubleshooting this isn't going to be easy, as you are finding out :thumbsup:.

FWIW, IMO: WMIACPI.sys is a Windows file that seems to be installed with SP2. If it's damaged, I suspect that the only thing that might cure it...would be installing SP2 or SP3.

If it were me, I'd simply do a repair install of XP, using my Microsoft XP CD and license.

That still doesn't clarify your potential RAM issues...which could be responsible for all this.

Well with one stick in I get

STOP 0X050 (OXB84C0058, 0X00, 0X8059BDC8, 0X00

And with both of the new memory modules in (toal of 4gb) the monitor lights goes yellow then green then yellow and the screen stays black, the computer continues to run tohugh.

If it helps i am running Windows XP 32bit, thay may cause a problm with having 4gb of RAM?

Sorry for posting late, I just did a memtest for one of the new ram modules, firstly by 14% the test already displayed over 1,000,000+ errors :S
Other things i noticed were that it said the speed was 400MHz when it should be 1066MHz also the timing said it was 5-5-5-18 when it should be 5-6-6-18

Would the memory be faulty?

Well...it COULD be faulty...but you can check the RAM module data...with another utility I consider reliable, SIW System Information for Windows - http://www.gtopala.com/. This tool will dsplay data under the Memory designation, you can crosscheck it with what Memtest86+ reported for each module.

If they agree, draw your own conclusions.

Sorry...my mistake :thumbsup:, I forgot about that.

Well, my experience is that Memtest86+ is accurate when it comes to timings and module...I can't tell you any more than that.

You need to test each module of RAM you have on hand...write down the timings and other specs noted by Memtest86+...and do some thinking.

Sorry, I don't really have any idea.

Although there are multiple instances of this same error message...I haven't seen one which conclusively pinpoints what it wrong and what steps can be taken to correct it.

Example: http://www.bleepingcomputer.com/forums/t/153175/blue-screen-io-error-verification-error-in-wmiacpisys-wmd-driver-error-20e/

It could be anything...and you don't really have any clues which lead anywhere.
