A8n sli premium cpu voltage limit ?

[LeeMc]

OK so I fitted my Swiftech kit without much problems and its running great and keeping everything cool ........lovely .......but(theres always a but ) I think my cpu can go higher than it currently is , 2.7ghz is no problem and is totally prime and superpi stable , go any higher and it'll fail superpi altho its stable in games and benchmarks etc , I can get to 2830 or so with it still being stable in games and windows but obviously it fails pi and prime virtually straight away , I'm currently running it at 1.55v which is showing as the boards maximum in the bios and I'm running the latest non beta bios which is 1009 i think but I've seen reviews on the net most recently at anandtech with the a8n sli premium listed as having 1.6v as max voltage.
With the cpu going that much higher than is prime stable without crashing in games I feel sure it will go higher with more volts and the current watercooling setup could certainly handle the extra heat no problem i'm sure.
My question is this :- Is there a way of letting me get more volts from this board than 1.55v?? , like the old abit boards like the bh6 and bx6 where you could flash to the next bios and if you set the cpu volts higher than std when flashing it gave you more in the updated bios or does it involve a volt mod in some way(which im not too worried about doing , i've volt modded boards and cards before so that shouldnt be a problem.)

Thx in advance

I had that problem when i had the asus premium. I say screenshots at 1.6v and aibooster even allows 1.6v but when changing past 1.55v the system hung. I tried all bios available up to 1008 beta i think and never saw an option for more than 1.55v. What i did notice was that at 1.55v asus probe reported it as 1.58 most of the time but it did fluctuate (apparently normal for this board). Let me know if you find anyway to up the volts on this board

Ok well after some seriarse googling the only way i've come up with is this , a volt mod basically , so its off to a local electronics supplier for me at weekend and get some trimpots ordered(yeah they never have stuff like this in stock even tho its listed on the net) , then I'm gonna have to rip me system apart again and get modding , its been a while since i soldered anything this small so its out with some old graphics cards and m/boards lying around in the loft and get practising I think.

Heres the mod , looks simple enough but when you eventually find it on the board you realise just how small this is :-

Then if all goes well with that mod I really do fancy the 7800gt volt mod too , here :-

looks sweet and not TOO difficult to do I wouldnt think , practice makes perfect eh ?

I would delete the reference to the competitor.

Volt modding GFX cards... ...you'll be TEC cooling and killing GFX cards left right and center in no time!

Good luck

Hehe well hopefully not , i'll be very careful and patient with adding voltage and with the current temperatures I have I think I've got quite a bit of headroom , anyway I'll let ya know how I get on.

Are those the same solder points for modding a 7800gtx 256, im thinking of doing mine but the pics ive found on the net are not that clear.
