4000+(San Diego) @ 3GHz...... - Page 2

post #11 of 18
Thanks Shadow for clearing that up for me. Now I got two more questions. Why is it called a rail and what was used to show those voltages?

most likely those aren't accurate.....Use everest home to monitor your rails to begin with. MBM is always a little quirky and needs to be setup properly to be anywhere accurate.
Even speedfan should show different readings than MBM

haha look at the voltages tahts what he means.

Its called a rail just due to terminology, probably has something to do with the fact that the old amplifier power rails used to be actual metal rails that allthe components drew their current off of. The voltages were shown in the system stats monitoring application that you can see at the bottom of his screenshot.

Hi floyd

just posting my finding here, cause i have a similar setup and am also attempting to break the 3GHz barrier so far have only been able to get to 2805MHz stable, have been working on the assumption that this is a vcore issue and sadly the A8N-sli deluxe only allows a maximum of 1.55V so looks as though am going to have to brave the plunge and get the soldering iron out.

Can boot up to 2.9GHz , but not prime stable and gives the ocasional BSOD when running long super pi runs.

Also just curious as to what your stepping is mines a KAB2E?

ADA4000DAA5BN
KAB2E0539DPMW
1336197J50159

Oh and the setting i'm running at the mo are
HTT 255
HTT x4
CPU x11
Vram 2.7
Vcore 1.525 (cpu Z is showing higer cause have been fiddling about and it fluctuates a little)

And some pics

I can get 3GHz easily. It runs OK for most apps but it'll never be "Stable". I can run Q4 w/no prob, but it locks up for CS:S.

well... got to around 2.9 stable (somewhat).... but i need more vcore, is there any way to get more with this mobo?
heard there is like a pencil lead mod or something....
post #18 of 18
There are loads of voltage mods for this board over at www.vrforums.com, but the chipset mod is the ony one that i know will work with a pencil. i did the vcore mod with soldering iron and variable resitor last night, I was cacking my self the whole way through, but it works fine and so far i can get 2.9 GHz stable, havn't got anyfurther yet cause had to sleep and have uni today, will try and post some pics for you tonight.
