good thing it doesnt really degrade performance by a whole lot, maybe 1 or 2 percentage.
2T will drop 30MHz in performance....read it somewhere so if you are only losing 2% you are actually either running 2T or 1T and not comparing the results properly.............where do you get the info for 1T ONLY or 2T ONLY At all times....bios OK...what about windows...SiSoft, A64Tweaker?!?
PLS beware that Sisoft Sandra actually reports 2T for all 1:1 settings regardless....bug in the software....if you are running a divider at 1T it will show it properly......A64Tweaker gives reliable settings......
Look i don't want to be a party pooper but asus guys have been waiting for a bios fix for 1T 250MHz ceiling since late last year and it still hasn't been fixed.....BUT as you said it actually works good on some machines and doesn't on others so it is promising
SOLO...since you run yours at 1T(i assume so) please let us know of the full setup so we can figure out or mimic this problem with other users......I think Solo is using the FX55 for his tests which may very well work better with these bios files as it is an older core CPU......it seems Venice CPUs are plagued with that problem ATM......
I read the first page but i couldn't see anyone running high multiplier stable at 300+HTT at 9,10 multipliers........week 17 3000+ venices are all easily doing 2800MHz which is 311*9......can anyone test if this board can do that or not.....

I would still reserve my judgement on video encoding jobies which i didn't see get much mention but it seems that 1T or 2T CMD rate will not really be as bad as i thought

Knew this myself after running a few simple tests.
1T v 2T means jack :banana::banana::banana::banana: in real world preformance - 1 to 2%, the only thing that shows a dramatic gulf between 1T and 2T is sandra bandwidth test....and we all know that to be a BIG wank which mean nothing at all. :fact:
OK two things:Quote:

Secondly the AN8 SLI (non-Fatal1ty) with heat pipe also has 3.55V and all the other options in the BIOS of the AN8 Fatal1ty SLI and Ultra with heat pipe.
I run 1T no problem.
OK...i would lean towards CPU support here...even though bios 13 supports venice it probably needs a bit more work....thanks bigtoe...i'm sure there's a contribution there already
i ordered the AN8 Ultra and will get it tomorrow to pair up with a 3000+ Venice 0517EPMW that does 2.8GHz stable at 1.52V.......i'll keep you guys posted about this....CPU was checked out in my asus board which i sold yesterday and it did 32M around mid-26m in 133 divider...so ram was 200MHz 2-2-2-5-1T...the CPU would probably top out in the 2.85/2.9 on air i'd say......Ultra mobo will have to go way past 300 to keep up with this CPU....

@ default i can do 1T without any troubles :)
Running now @ 300x9 with memory @166divider and still testing :)
that's what i want to see....that is the new UTT ram isn't it

Yea need like 3.8 for my BH5 Abusing @ 285Mhz.. :D Nice board stable and all.. :D i don't think DFI will put another 4V VDIMM option again, or they will make it optional, ect causing to much major problems for them.. Abit being sensible actually :D
what is the latest bios for this bios?
tictac, I've seen BIOS 13/14 uses previous CPU microcode, so I guess updating it would improve Venice/San Diego support ?

you would be better off with Abit + booster....or maybe DFI can resolve this problem with their boards with new revisions.....

i wouldn't try a booster on this board. it's getting the vdimm from the 5v line.
dfi is getting the voltage from that line with that jumper but if you're using the booster on DFI you'll drop it back to 3.3V line of course
if you are suggesting Abit vdimm voltage option is actually off 5V line I didn't know that.......please make it crystal clear what you meant there.....
can any of you Abit gurus confirm which line is used for RAM on these V2.0 boards with 3.55vdimm option in bios

hi m8
did you give it a bash...also why not try ultra as well....anyway i guess any 3.55vdimm board will do a similar job

well I would prefer the regular SLI version due to higher resale value when you want to sell it back.
You mean like so.Quote:
