Dual (or Quad) Cores cause crashes, but you may be able to try this as well:
1. Start EQEmu
2. Before logging into the login server, ATL+TAB out of the program and hit CTRL+ALT+DEL
3. Select the 'Processes' Tab
4. Find the eqgame.exe process and right click it
5. Select 'Set Affinity' and then chose CPU 0
6. Return to EQ and run like normal

I did this and now its giving me a memmory error and not allowing me to log into it at all. I am trying to change it back but it gives me access denied. I uninstalled and reinstalled and it is still giving me the same error. Anyone able to assist me with this issue and help me problem solve it?

Each time you load the game, it should reset the affinity settings, so that shouldn't be an issue unless you have a hung process or something. Have you tried rebooting your whole PC yet?

What memory error are you getting?

It's giving me Application Error This Instuction at 0x1000foce referenced memmory at oxffffffc. The Memmory could not read.

What OS and how much RAM do you have?

I've got 2k ram.

Uh, what? You mean 2GB?

What OS?

yeah 2GB. The game worked before this it was just choppy and I changed that setting and have redownloaded like twice. sucks my screen changes to some crazy colors when I click the Icon to log in. This happened right after I changed the CPU 0.

You still haven't replied to as what OS you're using, lol. :D

If you're using Vista there's no need to change the affinity for the CPU at all. If you're using Windows XP with SP2, you don't have to either.

I don't know how many times, I have to mention this. It seems like the old information that was posted is causing more confusion than anything. :rolleyes:

Also, what processor and videocard do you have?

I'm not sure this is true in all cases. I believe it is true for all Intel processors but some of the more recent AMD processors still needed fixes to resolve all multi-core issues.

The reason why I said that is because there was a memory address error in AMD CPUs with Windows XP in anything earlier than SP2. If anyone is running WinXP with SP2, then this hotfix should be included. Vista already has this as part of the OS, so it's not needed at all. :)

Intels do not suffer from this issue because of the way they're made. They handle CPU instructions differently than the first batch of AMD CPUs that were out on the market.

Also, if anyone has an AMD CPU that's a Phenom Quad Core, there's a TLB (erratum) that they screwed up on. Most motherboard manufacturers have released a BIOS patch, but some have just turned the other cheek. A good thing to check is by going to your motherboard manufacturer's site and see if they have a BIOS update. Should be something along the lines of "TLB Error Fix" or something.

The way to tell if you have a CPU that suffers from this is to check the model number. If it's a CPU that does not have a XX50 in the model, then it most likely has the faulty core. For example, the Phenom Quad Core 9600 has the TLB bug. The 9650 does not. Also note that if you do patch your BIOS with the TLB fix and enable it, you're essentially cutting your CPU's processing speed in half. So it's wise to check that it may be a possiblilty that your motherboard may already have this fix included with it and it's enabled if you have this CPU.

Also, there are memory patches for Windows XP that Microsoft has released as well. This was a hotfix mostly for games since the memory address was not being utilized correctly. But it's hard to find a link since this has all been included in SP2 and SP3 for WinXP. Even though you may have SP2 or SP3 installed, it may be a good idea to see if it's actually there by checking the KB number after you've installed it.


Here's some links.

Here's AMD's site for the CPU hotfixes and stuff. (It should be under Processor Drivers at the top.)
