Thread: MD5 Error

What game is this happening on? I'm assuming one of the BF2 games.

I would first try to re-seat the Sticks before jumping into a purchase.

Start by powering off PC, touching case to remove static build-up, don't drag feet on carpet, etc. while inside of case...

Remove both/all sticks and inspect gold contacts for discoloration or "burn" marks, dust, etc. - anything other than gold color.
Don't use Pencil Eraser to clean these if needed, rubber erasers will leave deposits and cause more troubles. Buy Dialectric (non-conductive) Contact Cleaner (spray can), which is made for this. Don't touch contacts with fingers either, this leaves oil and salt on them from sweat. Even a T-Shirt/Rag will leave lint. If in a pinch, and have an LCD cleaning cloth, this will suffice. (supposedly lint-free)
If they look OK, then plug 1 stick in same slot it came out of, and run Memtest again.
Check each stick by itself to try and find out if one or both sticks are faulty.
If errors persist, use same stick in another slot, trying all slots before starting new stick. This will show if stick is bad or Mem controller is at fault.
Repeat for each stick/slot combo you have. Tedious work, but might save $ if Mem controller or Mobo is a fault before buying new RAM when yours may not be.

PS, you can roughly test your RAM by moving a large (>600MB) file around a few times on your hard drive and then comparing the file size to it's original.
A little quicker, but not a true test.
Any lost DATA would suggest RAM read/write errors.

When i first saw the title i was like...why the hell are you using encrypted authentication (for those of you who don't know MD5 is the DoD standard for encrypted authentications between machines).

Follow the steps listed before me and you should be good to go. Theres a possibility you could have stuff on your MoBo contacts as well, so might wanna grab some compressed air.

Also you can try this...

If you are getting the shaders_client.zip mismatch error then this duct tape fix may or may not work for you:

Follow these steps closely:

1. Delete the cache data folder for PR. You can find this folder usually by going to
C:\Documents and Settings\username\My Documents\Battlefield 2\mods\bf2\cache\
and deleting whatever folder is there. This will force re-optimization for the game when you load into a map again.

2. Make a backup of the following file by renaming the file adding .bak to the end of it.
C:\Program Files\EA GAMES\Battlefield 2\mods\bf2\shaders_client.zip

3. Then COPY C:\Program Files\EA GAMES\Battlefield 2\mods\pr\shaders_client.zip to the previous folder in Step 2.

4. Restart Game and the problem may be solved.

To the post you just quoted. One stick at a time.

Seems the other replies believe that it mat be a software (game) issue, which could be true, I don't have BF2 or 2142, and that would be another route to explore, but, if RAM is bad, those steps could damage more files than what you have now.
(Including your Operating System...)

Sorry if I was vague, in my first response. It's not easy to guess the knowledge of the person asking questions about their PC troubles just from typed words...
I'll try to clarify my statement from earlier:

You should have 4 RAM slots in Motherboard, two should be a certain color, other two should be another color, this means there are two channels (2 colors) for RAM.

You said you have two sticks of RAM, leaving two empty slots.

If both sticks are in same color slots, they are in Dual-Channel mode, or running under two channels, or (two) Memory controllers. If one stick was in one color slot, and other stick was in different color slot, you were running Single-Channel mode, using one channel.
The preferred method is Dual-Channel.

In pic below (of my Mobo RAM Slots) there are two colors:
Yellow (Ch1) and Black (Ch2).
From top to bottom, Dimm1Ch1 / Dimm2Ch1 / Dimm2Ch2 / Dimm2Ch2



What I was asking to do was run a single stick, by itself, in each slot, and test in that slot for errors.
So, 4 tests for a single stick...
Then repeat 4 tests with other stick by itself.
Like I said: tedious work, but worth it, giving a true test.

If errors occur in same stick, in all slots: RAM Stick Faulty;
(replace one with equal brand/type/speed stick)

If errors occur in same stick, but only in one color slot, not both: Bad Controller;
(use other color slots/channel)

If errors occur both sticks, every slot, Bad Sticks RAM* ;
(replace both sticks)

*The last line could also be bad Memory Controller, but odds are 99% that doesn't happen at same time, but 1% chance it could (both channel controllers die at same time).

Hope I didn't add confusion, you could just buy a new pair of sticks and skip all this.
Maybe the Game Issue is what's a fault, but sounds like RAM to me.
Good Luck.
