I've seen this issue WAY BACK and dont' recal the board or the cause.
So please excuse if I missed it again in my search.
I picked up an ASUS M4A89GTD board and a Phenom II 555 BE.
+ rest of parts from old PC = G.Skill 2 X 8 gig RAM / 1100 Watt PSU / 4X RAID 0 baracuda's ...
I ran all my standard initial tests and all runs great. Unlocked the core (only 3 work...) but I only paid for 2.
Still stress test GREAT.
Went to OC ... 1st by upping the FSB to 225 ** and setting the multi to 16 (vs. auto).
Booted fine and CPUZ recognized as 3.6 G's ~ but when I started a program, the multiplier would drop to 4 (leaving me with a .9 G).
Went back into the BIOS and checked everything. Locked the CPU back to a dual core.
Booted and same issue? I know it's a BIOS auto option that I need to change, but I'm not sure which one?
NOTE: I can leave everything on auto (leaving the bus at 200) and up the multiplier to 20 getting a total OC of 4 G's with air cooling and no issues / 24 hours of solid stress testing and temps not breaking 43.
But as soon as I touch the FWB (change from auto to anything over 200 ...) I get that same on the fly drop in the multiplier down to X4
Anyone know which auto setting is the issue?
.... I'd change 'em all, but there's a ton (most are new to me and I've done this for a while now).
