Parity errors can only occur in the RAM (Memory) so I shoud think niether are right. That said however strange things happen to computers, so without a look at the offedning machine I cannot be 100% certain.

10 reasons why PCs crash-You must know tip 2


2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

Dell Optiplex 330,won't boot memory parity error, tried new bios battery, new ram stick, still won't boot,actually had two at same time the other I ran a advanced diagnostic test said hard driv


I found this

Customer's Optiplex 330 did the same thing today; no beep codes (due to lack of on board speaker). Solid/orange light on front of case indicates board or cpu. I isolated every component not soldered down (RAM, HDD, Optical, etc). Considering all the fans and lights on the MoBo were functioning, and no physical damage to the CPU was apparent, and the BSOD presented the "memory parity error; system halted" (meaning it's memory, graphics memory, or cpu and we've eliminated possibly CPU and RAM) my conclusion is that the problem resides in Graphics memory failure. Considering the error message is very vague and generally insists "motherboard", the gpu in an optiplex 330 is integrated ON the board, lumping it all together.

and general memory parity fail information

Is it a raid drive? If so you need to format it correctly. If not, check the bios setup and insure your uefi or ahci and legacy options are correct. Check the sata operation should be usb. Check that the boot sequence is in order. Give me more information and I'll help you

Getting the following error repeatedly: A parity error was detected on \Device\RaidPort1. Source: adpu320 Event ID: 5 Any help would be greatly appreciated...


Any "Parity Error" is from a communication error on the SCSI bus, and it's bad! Errors are a way of life, and the SCSI transceiver has failsafes to fight them, and one of these is parity. Consider it extra data that the controller sends when you transfer data to your hard disks. Once there, the drives transceiver does a simple ccheck and verifies that the parity is correct. If not, a Parity Error is generated.

99% of the problems surround the SCSI bus itself in the form of a damaged SCSI cable, loose terminator, or a bent pin on a SCSI connector (latter being most common). This error is more apparent after moving the SCSI devices, resulting in unplugging and then replugging the cables back onto the Targets (HDD, CD/DVD ROM, printer, etc.) or back onto the Host Bus Adapter (HBA - the 29320 in your case). Check ALL pins. You can try to straighten the pins, otherwise it's time to replace the cable. REMEMBER that terminators are a must and can also cause Parity Errors if there is no termination present on one end of the bus or the other.
This coming from an ex-Adaptec employee and support person! :)

Best of luck

I'm thinking you should be checking the drives. If one of them is failing, you will get parity errors.

Parity error issue with TF85 DSSI based on VAX4000 - 700


If cleaning the heads using the cleaning tape did not help, then there are 3 possibilities that I know of:

1) The heads are sufficiently dirty to require direct cleaning with a more powerful solution.
2) The heads are defective.
3) The heads are out of alignment.

Parity errors are not usually controller problems. If the head alignment has drifted enough, you may be missing a track when recording. An initialization includes writing format information at the beginning of the tape. This is "re-read" during the process to confirm correct writing. This is the part that is failing.

Keep me posted.

Hardware halfunction


Hi!
This behavior can occur if a hardware component malfunctions, or if there are damaged or incompatible drivers installed. As with VISTA!
To try to resolve this behavior, use the following troubleshooting techniques. Because Windows can display only basic error messages when hardware malfunctions occur, troubleshooting can be difficult. Most equipment problems center around the motherboard, the RAM on a motherboard or on an adapter, or the cache memory on a motherboard or on an adapter.
Remove any adapters that are not required to start the computer and run Windows. In many cases, you can start your computer with only the drive subsystem controller and the video adapter.
Let me know.

Error code 10-fc06-002 in toshiba a200 after running recovery disks


This is a toshiba error when running recovery discs on your machine. There are two reasons that this could occur, one would be corrupted Recovery Discs and the other is bad hardware (Hard Disk Drive).


While running a full system recovery from the Recovery Media, the installation may fail -- and display one of the error messages listed below. Possible causes of these error conditions are listed at right. Use this list as a troubleshooting guide -- not as an absolute list of causes, as there may be others.
"An error has occurred. ERROR :10-FC10-1710" -- may be caused by a faulty hard drive.
"An error has occurred. ERROR :10-FC12-0241" -- may be caused by a faulty hard drive or defective memory.
"An error has occurred. ERROR :10-FC12-045D" -- may be caused by a faulty hard drive.
"An error has occurred. ERROR :10-FC06-0002" -- may be caused by damaged recovery media or faulty hard drive.
"An error has occurred. ERROR :10-FC12-0970" -- may be caused by defective memory.
