Failed Memtest...Help!

September 10, 2010 at 14:41:45
Specs: Windows Vista
I just bought new ram for my hp m8300f desktop and I took out the old ram and put the new ram in the first slot of both of the dual channels. So, each channel should have been running a gig. I put on memtest and it failed. It got 98% through Test#6 (Moving inversions) and there were 2 errors and 2 passes. Below it says 'unexpected interupt- halting cpu'. Does anyone know what I can conclude by the failure of this test?

Go to the link below and expand the motherboard listing. Look at the memory section to determine what type, max. capacity and speeds.

Either the RAM you bought is not compatible with the board or it is defective.

What exact RAM did you buy and where did you buy it?

Should have also mentioned that you should make sure the memory modules are fully seated and the locks on the ends are engaged.

Memory normally will be configured to run at the specified voltage settings. This is not always the case. Running RAM at the wrong voltage could also cause errors. Especially if the voltage is set too low. Too high will just eventually fry the RAM.

Normally I worry about any memtest failure. Only one time did it fail and still be correct. It finally turned out to be a way dell put usb support in. Most times a fail is a real fail based on bad ram or other reasons.

Be sure bios setting are set at the correct setting for the ram.

It is still possible that memtest is wrong.Try microsoft memory diagnostic and other versions of memtest too.

Why did it take me over a year to phone in a problem to ATT?

How do I get into my bios options? I go to the setup menu when my computer startsThe pack of ram says compatible with 400, 533, 667 MHz but when I run memtest it came up that my ram was set at 430 MHz. Is there any way I can change these settings? I was thinking about flashing the bios because someone told me that might help. My computer has not done a BSOD since I put in the new ram, which was why I replaced it to begin with, but now it freezes. I think its because of the MHz, is there any way to lower my bios setting to 400 MHz?

Without more information on what hardware you have we can't answer those questions.

Download SIW and use it to find out what motherboard and processor (CPU) you have and then post that info here. Get SIW at the link below.

I removed your second post. Stay with this one. Use SIW to answer my questions and maybe we can sort out things. I sounds like you have manually set a FSB multiplier wrong. In essence, you may be overclocking your CPU, which may be the cause of the BSODs.

In addition to the the information I requested above, post the information on the RAM (memory) you see in SIW.

If you go to they have a Scanner Tool to determine the correct memory, saying it is compatable with speeds is only part of the story, voltage and CAS are also important...

You are currently running mismatched modules. Read for yourself.

Slot 1 had Qimonda 512MB of DDR 667.

Slot 2 has PNY 1024MB of DDR 800.

Timings are different too.

Either you bought mismatched RAM or you have mixed up the RAM and installed one old and one new.

According to the link I provided in #1 above, your motherboard supports:
Athlon 64 X2 with Dual Core technology up to 5600+ (up to 89 watt)

It appears you are running a Athlon 64 X2 Dual Core Processor 6000+. That CPU draws 125W and doesn't appear to be supported by your board or BIOS.

Did you assemble these components yourself?

No I did not install these myself until recently. A few weeks ago my computer started getting BSOD's and I looked on messages boards and the errors (which were memory management, irql less than or equal, page fault in non paged area, etc) pointed towards faulty ram. I did memtest but became impatient so I quit it and just decided to buy new ram. I pulled out the ram in the 2nd channel which was 2x 1GB, but unfortunately I didn't think to replace the first channel which was 2x 512. I showed a guy at bestbuy what my ram looked like and he gave me the same ram (which was PC2-5300) that I pulled out. I guess I should have checked the MHz speed. When I put both of the gig ram sticks in the 2nd channel the computer wouldn't boot, it would just stay a black screen. You said that the timings were different? I've tried a few different combos for the ram but for some reason this is the longest my computer has lasted in the last 2 weeks. Its been on for a few hours, multitasking and hasn't frozen or BSOD'd. I don't think it'll last too long but id like to fix it soon. Should I buy new ram for the first channel?

You don't have the RAM paired up correctly. The matched pairs must be installed in the same color slots. Install the the old RAM in the Black slots and the new in the Blue slots. Below is an excerpt from your manual. Link to manual at the bottom.

· All DIMMS must be of the same density (256 MB, 512 MB, etc...)
· Same DRAM chip technology (x8 or x16).
· All either single-sided or dual-sided.
· DDR2 and DDR3 support Dual Channel mode. The same type of memory must be matched into the same matched slot for Channel A and Channel B. Usually the memory slots are color coded to make it easier to understand.

I asked about the CPU that you have installed. Are you the original owner of the HP? Did the CPU that is currently installed come installed when the computer was new? That CPU may not be compatible.

Yes, I am the original owner. I tried installing exactly what was installed to begin with when I bought my comp. I replaced only the GB rams in the 2nd two slots. And I left the 512 pairs alone. The thing is when I put in the GB rams in the correct slots the computer would start but I get a blank black screen like its not reading my monitor. If I removed the 512 pairs in the 1st two slots and put only the GB pairs in the blue slots in back would my computer start? I think the GB rams are just incompatible with my computer because they are about 2 years newer than my computer. I know that the 512 rams are compatible. I should probably take everything out and just leave those 2 in and do a memtest. Last night I spoke too soon and I awoke to a BSOD.

If you suggested I pair them I think so...

The first channel I had (512MB x2)
The second channel (1GB x2)

When I do this my computer boots but the monitor screen remains black.

Then try with ONLY the original pair of 512MB sticks.

Ok now its been a few weeks later and I cannot take the BSODS anymore. The ram I bought is obviously the same, but the speed is different so it is incompatible. I can't even start my computer now so I just need to replace all the ram. Is there any way you can tell me exactly why sticks I should buy given the specs I listed above.

The original sticks were
(2x) 1GB 2Rx8 PC2-5300U-555-12-E0
(2x) 512MB 1Rx8 PC2-5300U-555-12-D0

Apparently the ones I bought from best buy recently are not compatible with my MHz speed so can someone point me in the direction of a place that I might purchase these exact sticks with the correct speed. I want to buy online this time so please help me solve this issue.

As was stated above in #7, go to and use their online scan tool. It will tell you exactly which modules will work.

Did you figure out how to enter the BIOS screens?

Enter the BIOS and set the screens that deal with the memory and CPU to auto.

You have 4 sticks of RAM in 2 matching pairs. Running either pair by itself should be OK.

Try installing ONLY the PNY sticks. Leave the others out.

Acccording to HP your computer came from the factory with the following RAM installed. 3072 MB(2 x1 024 MB) ( 2 x 512 MB) (expandable to 8GB)

Running more than 3GB of RAM with the 32 bit version of Vista is a waste of RAM.

My computer won't even start now. I can get the first blue screen where it says 'recovery' 'setup' etc. but I can't get any further because the screen goes black. The ram I bought isn't compatible with the MHz speed and I think that's why I have been having issues. I also cannot find the BIOS options. I tried the startup setup but no where in there does it allow me to control the BIOS, I have been looking for this forever. All I have right now is the 2x 1GB sticks that I just bought, and the 2 original 512 sticks that the computer came with. No matter where I pair the GB sticks the computer will not start (ie. first or second channel). When I put one 512 stick in the first channel, and 1GB stick in the second channel the computer was working, but not anymore. For about two weeks it worked, I still got a few BSODs, but not as often. I think the 512 sticks might be bad, and the 1GB sticks are just incompatible. This is why I wanted to buy new ram, but I wanted to make sure that it was the same as the factory installed ram so that I know its compatible.

If you are getting that screen you have already gone past the option to boot to the BIOS (setup).

Your computer is probably not starting Windows due to all the bad shutdowns.

Wasn't the computer working with ONLY the 2 512MB sticks originally?

When you install RAM with two different operating speeds the RAM normally just runs all the RAM at the lower speed.

If the faster RAM is installed in the first memory slot the memory controller may try running all the RAM at the faster speed, which can give you BSODs.

The 512s are the slower RAM, so they should be in the first slots.

Are you sure you are fully inserting the modules?

Try snapping each module in and out 5 or 6 times to burnish the contacts.

Go to the link below and expand the memory listing. You will see that both speeds you have are supported.

If you run a memory test and you get failures then the RAM might be defective. Could be dirty contacts too. HP probably doesn't allow you to perform any memory tweaking in the BIOS.

Watch your screen messages as soon as you start up the computer to learn what keystroke/s to use to enter the BIOS (setup). You must act fast.

Ok so my problem is back again. Actually it never went away, but now its worse than ever, BSOD's galore. The new BSOD message I've been getting is 'bad pool caller', and another one that just says that it tried to access memory in a non paged area or something to that extent. At this point I am through trying to figure out where the bad ram is. I think the 512's are bad, and the 1gb's that I bought are just incompatible. I am willing to just say screw all the ram I have now and just buy some new/compatible memory. If anyone can link me to a site where I can buy affordable ram that would work with my specs it would be greatly appreciated. I am tired of trying to figure out where the bad ram is, memtests just take way to long. Thanks for the help.
