hei... that bios 14 didn't mention anything about previous board... are you sure it is build for this board... ? :hammer:
Check the change log
Code:BIOS release 1.4 for AN8-V V1.0
Release information:
[ENGLISH]
1. First release.
2. BIOS compiled date: 05/20/2005
You guys need a bios that sets the dram drive to weak, then you will stand a chance with TCCD.
hmm weird, its running fine?? I dl'd it on another forum that said it was for the Fat SLI. Looks like I'm going back to 13 lol.
Tic: Can you recommend some settings for me to try in order to get the board stable with my OC? I am getting some weird problems like CPU-Z not being able to tell my the mhz of my memory and clockgen says my memory is running -100mhz? Not sure what is going on, but all this was before I flashed the bios so its a non-issue.
Actualy the board has a DDR Ref Voltage option which when set to -50mV boosts my TCCD's up to DDR600 form 275 MHz max. Only that whatever I do at DDR600, I can't seem to pass test #8 in Memtest (#5 runs perfectly well ~20 passes). That is with 2.5-4-3-8 1T (Read to Write delay set to 2) and 2 sticks of 512 MB (Corsair TwinX1024-3200C2PT rev 4.2). With only one stick I can pass all Memtest tests and it is Prime95 stable up to DDR618 (this tested with both sticks, one at a time). I guess it has something to do with the DRAM Drive Strenght you mentioned... but I'm wondering about the termination resistors near the DIMM slots (DFI has them in double)... I think this has something to do with it.Quote:

Also... with 2x 256 MB TCCD (Corsair TwinX512-3200C2PT rev 4.1) I can easily pass DDR600 in Memtest and Prime...
Another thing worth mentioning... the board seems it cannot POST above 278 MHz with RAS to CAS set to 3... and RAM isn't an issue here. ;)
Just flashed to the 1.4 bios.....no probs here.....i too was not sure as the readme does not reference the SLI....but it was in the same directory as the 1.3 on both USA and Taiwan plus the nameing of the bios was incremental so i took my gonads in my hands and flashed away.
Will try some more settings to see if i can get this thing at 300 stable but im sure like Bigtoe says its to do with drive strength

Another tweak would be to remove the Dram termination resistors on the board, replace them with pots and tune them to suit the TCCD or which ever ram you are using, this tweak alone could ramp up the fsb by 30MHZ or more.
:woot: damn dude...you are Solo....why didn't you say something:sick:why didn't you say something.....
love your work on other reviews.........:clap:

I am running everything STOCK on this new system for now until I figure out these settings and even have my ram running in auto. Video card is running same speeds as my AGP, except this one is PCi-X
Pretty impressive.. :clap:
i've seen 500MHz on DFI a while back.....very hard to compete with that.......but 371 and 385 are worthy to mention....my Asus goes to 325MHz at 8xmultiplier....i tried 335 but UTT RAM showed some errors in memtest.....i am not the type to voltmod but it would be possible to ho higher i guess with CPU and RAM at higher volts.....330Mhz is roughly the limit at Asus factory configuration I guess

I am really confused why the heck my CPU-Z and Clockgen cannot show me the speed of my ram..
Varz: I am mainly interested in your voltage settings, as a lot of those settings were not present on my nforce3 board. Good OC btw. I will be happy with a 260x11 but I can barely do 240x11 right now @ 1.65V =|
nice work

So bigtoe, just to confirm, if we run high vdimm RAM on A64, we should set "weak drive strength", right? Also, if I remember properly from one of OCZ's memory tuning threads, all "even" drive strength values were "weak" and "odd" were "strong" or was it vice versa?Quote:

Ok this is quick and dirty OC but this board has so much potential.
I really think we are going to see some great Overclocks with this board.
Heres my 3200 venice @ 290 x 10

nice work....what venice do you have...week and all.....give that X2 a go as well
looks like the new Asus premium board is a really nice OCer as well....DDR640 1:1 1T on TCCD outch!!!

Sound Blaster Audigy 2
OCZ PC3700 Rev3.0 Gold 2x512
I cannot get this thing stable even at 240x11 with 1.60V!! I have to be missing a setting.. Screen shots on the way :)
ram settings on auto, cpu set to 240 HTT, 4x HT, 1.60V, 2.80V for the ddr, 1.4 for DDR VT Ref.
http://img201.echo.cx/img201/1214/cpusettings8ho.jpg
http://img201.echo.cx/img201/9823/cpusettings23gg.jpg
You are running Memory clock higher speed that HTT speed :)
that is the limiting factor... Get sisoft sandra bench...
can you recommend me some timings for the memory to try with this ram? I didn't have this many options with my K8N Neo2. ;)
Start with 240 HTT,
4x HT,
1.60V for CPU,
2.80V for the ddr,
1.4 for DDR VT Ref
Ram Settings :
DDR Clock : DDR400 (1:1 sync)
CAS Latency : 2,5
row cycle time : 14
row refresh cycle time : 24
ras to cas delay : 4
ras to ras delay : 3
min ras active time : 7
ras precharge time : 3
write recovery time : 3
write to read delay : 2
read to write delay : 4
Dram command rate : 1T
burst length : 4beats
bank interleaving : enable
increase HTT with this setting see where you max out ... GL :toast:
Here we go :toast: I had figured me up some settings from your post on like page 7 so here are my results:
http://img130.echo.cx/img130/358/tweaked5ie.jpg
http://img123.echo.cx/img123/3685/tweaked22co.jpg
Needless to say if these settings are STABLE without exiting games and no blue screens, I am pretty happy :) That is a 400 pt increase over my K8N Neo 2 with same settings and slower mhz on the cpu!! I wonder if I swapped to Mushkin Redline if I could get 14k pts in 3dmark03 : :woot: :banana:
nice result... :up:
push up that HTT there is still some headroom... :comp10:
ok tic tac which should i experiment with now since i buried the original fatality. an8 v2 or one of the sli boards. i have no plans on using sli however if they seem to be yielding better results ill get it.or is there plans for a v2 normal fatality?
I want the AN8 Ultra.
It should only cost around $130, maybe $140 max. It seems that it's not for sale quite yet, but it's almost identical to the AN8 SLi (Non-Fatal1ty version) which has been out for a week or so now...so I don't know what's taking so long. :(
Wow. Lot's of useful information! I'm thinking about getting the SLI instead of the plain Fatal1ty AN8 now. It looks like a better board for a lot of reasons.
Chew... i have no idea if there will be any V2 Fatal1ty AN8.. :-/

I just wanna get this straight are these the only abit boards with 3.55vdimm?
Abit AN8 V2.0
Abit AN8 Ultra
Abit AN8 Fatal1ty SLI
Yeah, but that's just a pre-order, tictac. Not in stock. :(Quote:

I think Oskar Wu should go back to Abit where they can better follow through with his designs. Better quality control and better testing methods. DFI is still too spotty
Just wondering as all you guys are heading for 300MHz what am i doing wrong cant get stable over this.......
Change the following and keep the rest of what you already have on the RAM.Quote:

Change from 1T to 2T...
Bank Interleave Disabled
Make sure your giving the ram 2.8 or 2.9Volts
then move upto 300 Fsb and change multi to 10x
If that works then move the 2T back to 1....and test.
Then try bank interleave on and test
OK cheers whats Tcl can't find it ????????
ok sorry found it...tried that and keep getting message at boot up ......"Warning your in safe mode your bios will be rest f1 to continue del to enter bios " cant seem to get the magic 300MHz
They are already on the 4th revision of the board!!!!! :slapass:Quote:

If DFI dont get there boards sorted then i will be looking for a more stable product.
The Abit is looking tempting at the moment but i am in talks with Abit about changing the bios to support the Drive strength option amongst other things.
Lets wait and see over the next 2 or 3 weeks how things pan out.
My San Diego is garbage, very poor overclocker due to the amounts of voltage it needs to be stable. It also shuts off the comp if it doesn't get the voltage it likes :( (did this on my K8N Neo 2 as well, thought it was a bad mobo.) I will probably ebay this one and get another.
What are the Ram dividers available on these boards?

the drive strength option in the abit doesnt allow for a weak drive strengh thus the board is very hard to get to 300fsb in sync or higher however i did find timings that were 24h prime stable however around 36 hours i would get one error. they are posted in the xtreme bandwidth section.http://www.xtremesystems.org/forums/...ad.php?t=58112Quote:

Any problems with 1T?
Here i'm having problems with 1T bios 13 with G-Skill LA.
no 1T problems on my board.
Can someone tell me me what the CPU Ref voltage should be when overclocking?

This board is for a review, maybe its defective, i remember only my third DFI was ok.
so whats the verdict here do i go with the Fatal1ty or the DFI SLI?
if you're going to run BH5/UTT Abit is the only choice as DFI is defective

some serious OCs in sig.......Abit needs a monster OCer owner or two to squeeze the bejesus out of it....:devil:......

Btw-I ran 310 HTTx9 last night 1.65V with my OCZ memory on a divider no problem. I like my system running 1:1 so I put it back to 245x11 for right now (my processor can't do much more without some kind of shutdown or exit out of a program.)
This board has serious potential in it, give it a few more bios updates and tweaks I am sure it will be very comparable to the DFI. With ATI's chipset coming out this board is perfect to hold me over until I start seeing reviews of those boards.
And btw, I have used ABIT for many years with the NF7-S being the only board to ever die on me that I needed to RMA. I still have a KR7A-133 (something like that :D ) running in my wife's machine with no problems. I guess every person has different luck when it comes to hardware :stick:
so are there only 2 abit boards atm that have the 3.55vdimm option?
hi m8 i think 3xboards....someone mentioned a third one here....tic tac will know

this was a few years ago, i believe they use top quality caps these days. I mean if u really want to dig up old news, I think we can easily find someone with a pile of dead DFI boards...wait...no one bought them back tehn due to lackluster QC :p:
Strange, the Dram divider is selected through Bits 22-20 of DRAM Configuration High Register:Quote:

110b = reserved
111b = 200 MHz
Now the reserved values are 120, 140, 150 and 180 Mhz. So how can the abit board select these memory divider values higher than 200 Mhz?
not sure how do they able to do so...
but from AMD 64 datasheet... it is writen over there that
http://img269.echo.cx/img269/6834/imag00039xw.jpgQuote:
"... It is possible to program this field for higher frequency than maximum allowed by the processor."
well I can't seem to get 1T to work or clock higher than 2.35ghz even at 1.6vcore. Although I did get as high as 320htt but that required me to use the 266 mem divider. Looks like my Corsair BH6 sucks. Won't do 250htt. The comp just powers down at 250htt max vdimm. Same thing with 1T, comp just powers down even when the mem runs way below spec. Venice don't like 1T?
I'm sitting looking at the Ultra bios the one with heat pipe and it has 3.55 volts for the memory as well !!!
my asus board gives me options for dividers higher than DDR400 i'm pretty sure

Got me AN8 SLI (non fatality)
Set it up didn't bother reinstalling windows (waiting for dual core for that). Bit messier wiring than DFI NF4 on my Li-Li PC-V2000 Plus due to location of FDD connector and extra power for PCI-e.... I might use extender for that cable to make it neater later and longer FDD cable (or relocating FDD bay to top of case)
vdimm looks good, my pair of stick works fine as it did on DFI (mushkin blue). My overclock didn't change much at all. (gained 20mhz but could be due to just remounting hs again). Interestingly, the temp readout is.... 10c higher than was on DFI. I think ABIT is still keeping their long tradition of +10c vs other mobo tradition. (Their thermal shutdown defaults at 85c... vs 75c of others).
Bios is streamlined and clean enough to feel plesant. The overclock on fly is cool feature... except, you can only do it once per reboot -_-;
Now, I didn't see alarmning temp on my NF4... but since my mobo is upside down... wonder how effective that heatpipe would be :P Temp doesn't look bad though not going over 40c...
With my mouse and keyboard combo as well as many USB devices, I sometimes had to start system again just to get mouse back (saitek keyboard, Razer Diamondbak, USB scale, UPS, Printer, and another hub in monitor which has my Treo 650 and few other junks, as well as card reader in 3.5" FDD)... Haven't had this issue at all in this mobo.
Also, it initializes a lot faster than DFI board... I was rather surprised at how quick it boots up. (I think I've been tamed by DFI's slow initialization sequence)
Just about all fan headers can be controlled and programmed for fan speed for those who seek noise level reduction solution. (saw 5 in quick glance... there might be 1 more somewhere)
BTW, big typhoon is not the best candidate on this mobo as heatpipe is going to lay horizontally. In fact, it works only as good as CNPS-7000 Cu... -_-; I think I am going to sell typhoon I just got and grab new Zalman when it comes out... what a waste of money and 1.5 hours of lapping today (base was that horrible... I actually had to use 400 grit to start)
warning... it use same socket retention kit as DFI... no idea what Abit is thinking... -_-; Is asus and msi like the only company that uses standard mounting now?
Anyway, money well spent so far. Bit less noisey and attractive mobo.
Edit: I got the typhoon mounted wrong... Found out it still does perform about 8c better than Zalman CNPS-7000cu... after couple more remounting... There is gotta be better way to mount this monstrosity.
Yes it seems all boards with heat pipe are version 2.0 and thus 3.55 volts memQuote:

Oh... on side note, I wish Abit did get to this board slightly sooner. This board is my choice over DFI NF4 Ultra D already after hours of using it. (no quirks so far with bunch of things I knew would be marginal on DFI board). For those with 5v rail and dead memory syndrom on DFI, this is board to move onto for safety of mind for time being. I am running 3.4v on this sticks for fun right now... :)
great work......so all heatpipe ones are with high vdimm....very very nice

The ABIT simply does not let me OC to what the Neo 2 did with this chip, but that is a good thing b/c what I *DO* get out of overclocking is rock solid. I am running a modest 235 HTT x 11 (yup, thats it) but with 1.475V which was IMPOSSIBLE on the Neo 2. The temps on the AN8 are really high compared to my Neo 2 but I know they are false readings. Mounting my XP-90C is questionable due to the way the base goes around the socket. I think I should mount it with the heatpipes facing the ram because right now I have it the other way and I do not think its making good contact.
Either way I love this board for its features and speed. My computer is faster using stock settings then my OC on the Neo 2. I have a Venice on the way with some Mushkin Redline so I'll post those results when I get them.
BTW I am a hardcore gamer and do some 3D graphics on the side, so I actually *USE* my computer to do things rather then just benchmarking. I can tell you I could not ask for much more out of my system right now, especially when I have FX performance out of a $300 chip, and do not have to worry about my parts dying pre-maturely. :woot: :toast:
anyone else with 1T issues? I might just have gotten a bad board like someone suggest over at the ABIT forums.
Did you try diff CPU? I've had diff CPU working 1T on both boards (DFI & ABIT). But than I've had Venice which doesn't like 1T on either board... (windows doesn't finish booting up)... figures...Quote:

I have been talking to Abit guys, I suggested a ton of bios options need adding and some tweaks to get the board clocking TCC* better. I get a board soon also.
No, the AN8 Fatal1ty doesn't have the overclocking features the following boards do:Quote:
