Hi,

I bought the a7v-e the other day, stupidly assuming that because the -e stood for "enhanced", it would, at worst, be as overclockable as the a7v, and at best, even more so. Well, if I'd bothered to look at the manual on the asus site before ordering, I'd have found that not only is there no vcore adjustment in either software or via the dipswitches, there is also a limit of 110 on fsb speed.

I realise that fsb speeds of above 110 are very likely to cause problems with cards on the pci bus due to it running faster than it should, but I see from the a7v manual that an fsb speed of 133 results in a perfectly normal pci bus speed of 33, so this is what I would like to try on my board.

The a7v-e manual, however, only lists 4 possible speeds settable by dipswitches: 100, 103, 105, 110. But, there are 5 switches used to set this, so I'm thinking there is a very good chance that there ARE other combinations, but that asus just haven't printed them in the manual.

And that brings me to why I am posting this - I am hoping that someone has this information, and could post the "hidden" dipswitch settings. Or even if someone has already gone down this route and knows that there are in fact no other settings, and that I'm wasting my time, please post to let me know this.

If I don't hear back from anyone, I will try this weekend to set some different dipswitch combinations, and see what happens (and will post the results here). I assume that if I was to set a dipswitch combo that isn't supported, that the board will not implode before my eyes, but again, if anyone knows that this is in fact very likely to happen and there's a high chance of me trashing my board, please post to tell me this.

Cheers
 
Same stupid problem here....Is that ever lame dude.
specially lame when u can read "200FSB" on the bloody Box/Manual...
I did t even think double check that, because I really didt think anyone made crap stupid stuff like that.
And with a chipset that support way more then 110FSB,,,,I mean give 133fsb and ill be happy...

!!!!!!not even 133fsb!!! J......... thoce guys Suk

110 FSB TOP! what the joke
 
The A7V-e board does provide higher FSB than 110. I have experimented and found out the following settings for SW1:

111:10010
113:11100
115:10100
117:11000

I have not been able to go any higher. Maybe if I had PC133 RAM. My duron is running stable at 117x8,5=994 with VCore 1,85. I have found no way to raise VCore than by shorting bridges L3 (I think it was) on the CPU.

I'd say just try different settings out.... most likely, there's a pattern and you'll be able to figure them out. Is this board KT133E-based by chance? If it is, then it SHOULD do 133 FSB, as the Abit KT7E is able to. As far as the 200 MHz FSB thing, they're referring to the fact that it's a double-pumped 100 MHz FSB, so the effective data rate is the same as a single data rate 200 MHz FSB. (Which means 133 MHz FSB equates to 266)

i have asus A7VE too and it can reach higher the bus than 110 and i want to ask you to behrens how can you raise up the bus into 117
duron 700@1000 1.85v 100x10
 
to go to 117 Mhz you have to use the jumpers on the mobo. Jumper settings for FSB are:
111:10010
113:11100
115:10100
117:11000

I found the same situation myself. I tested ALL of the possible combinations (32) and found 17 don't work, of the 15 that remain only the ones listed above give FSB speeds above 110mhz. I do have PC133 ram and that doesn't effect anything in this situation. As for the L bridges I believe you want to short the L7 bridges, not the L3.
