so would i be correct in saying that blowing the 5th L3 bridge on a tbredB 2100+ I will get +8 to any multiplier I choose in my bios? (A7V133)

ONLY if "your" mobo/bios/?northbridge? co-operate.
And then only adds 8X to 5X, 5.5X, 6X, 7X, 8X, 8.5X, and 9X settings, because of the nature of AMD's Multiplier Code.

6.5X + 8X = 14.5X = Reserved, might not boot.
7.5X + 8X = 15.5X = Reserved, has Remapped to 22X.
9.5X + 8X = 17.5X is Remapped to 18X.
10X + 8X = 18X = Reserved, has Remapped to 23X.
10.5X + 8X = 18.5X = Reserved, has Remapped to 24X.
11X + 8X = 3X = Mobile CPU code, no boot??
11.5X + 8X = 3.5X = Mobile, has Remapped to 19X.
12X + 8X = 4X = Mobile CPU code, no boot??
12.5X + 8X = 4.5X = Mobile, has Remapped to 20X.

Isnt the last L3 on the Tbred 2100+ open already as the default multi is 13 hence the 8x is set to high already?

It was on my mobo,unlocked and set to higher multipliers.should be on others as well.

Yes you're right, but we ignored that...focused on the +8X question since most people assume ALL 5X-12.5X settings get 8X more...and like "Buttercup" in Pirates of Penzance?? sang, "All that glisters is not gold".;-)

I'll get my 2100+ tomorrow and see what L3's are cut then as some more questions!!!

Pictures of my 2100 & 1700 Tbreb Bs..

If anybody's interested in which bridges are cut, here are pictures of my...

2100+ Tbred B

and 1700+ Tbred B

Anybody know the lowest voltage you can use to blow a bridge ? Most posts I've read have used 9V., but would 1 1/2v. work ?
