It seems logical that it might make it faster since it is less work the CPU has to do. -YB Reply With Quote 10-10-02,06:27 PM #2 donny_paycheck View Profile View Forum Posts Inactive Super Quad Mod Join Date Oct 2001 ECC slows down any memory acces, so mine is disabled.

I read Tom's guide on BIOS settings, but I don't think he mentioned this. Also, should the setting http://www.overclockers.com/forums/showthread.php/129267-CPU-L2-Cache-ECC-error-checking for 'Video RAM Cacheable' be enabled or disabled? I'm looking for performance here.... A few system specs that may be relevent: 256 Mushkin High Performance RAM 256 Crucial Cas2 (Coming Tuesday) Athlon 1ghz Herc. gf2gts2 32mb #1 theNEOone, Jul 29, 2001 wfbberzerker Lifer Joined: Apr 12, 2001 Messages: 10,423 Likes Received: 0 what kind of motherboard do you have? if your computer is set up https://forums.anandtech.com/threads/cpu-l2-cache-ecc-checking-enabled-disabled-in-bios.586218/ as a server, you may want ecc enabled for safety. however, if you just have a normal computer, you may want to disable ecc as it causes a performance drop. (for future reference, buy normal ram, not ecc, if you dont need it for a server, because its cheaper) #2 wfbberzerker, Jul 29, 2001 theNEOone Diamond Member Joined: Apr 22, 2001 Messages: 5,733 Likes Received: 1 i have an abit ka7-100 i don't have ecc ram....ack! #3 theNEOone, Jul 29, 2001 Sugadaddy Banned Joined: May 12, 2000 Messages: 6,495 Likes Received: 0 Look here. #4 Sugadaddy, Jul 29, 2001 pm Elite Member

Here's the specs:Motherboard: Gigabyte MA770T-UD3CPU: Phenom II 545 (RB-C2)RAM: G.Skill 4GB DDR-3 1600OS: Ubuntu 10.10 Maverick with 2.6.35 kernelI am running everything at stock speeds and voltages. I did try to overclock for a couple of days but never could find a decent clock that would pass Prime tests overnight. So, I have been at stock for the last couple weeks.Anyway, l2 cache ecc I have noticed over the past week or so that I am getting hard lockups every few days. It seems to almost always happen while I am in my browser and watching videos. So, finally, I decided to check syslog for errors and lo and behold I find a large number of "Machine Check Exception" notices. So, I installed mcelog to discover exactly what these errors are, and I find that most of them are exactly the same. Here is an example:HARDWARE ERROR. This is *NOT* a software problem!
