*New* ABIT Fatal1ty AN8-SLI = 3.55V Vdimm

[Delirious]

last i read your bpard was doing good at like 295HTT, what happend?

it does do 295 fairly well as long as its 2T as soon as i switch to 1T i get all kinds of issues. Also if i shut the computer down it wont power back up without the cmos being reset.

I have tried and new cmos chip and every bios they have. It has that issue with and without the oc.

Other than that its been an ok mother board.

no issues with 1T on mine

Just wanted to point out: only 10 more posts 'till this thread reaches 1337. Well, 9, counting mine.

How... monumental.

Well after messing around with the modded bios 19 from celemine1Gig (needed it to access different boot devices on my RAID card), I can't say that I have noticed any improvements over what is possible with the tictac modded bios 13. About the only thing I did notice that was different was that bios 19 increased the Read to Write delay (Ttrw) to 4 regardless of what is it set to in the BIOS menu. I am convinced that A64Tweaker is not simply misreading the value since the results from Everest seem to bare out that bios v19 has lower values than tictac's v13. If I manually set the value back to 2 using A64Tweaker, I again match the previous v13 results. Given that I have noticed slight instability (fails after 7-8hrs stress testing) if I use Ttrw of 2 at high FSBs (290-295), I am theorizing that any added stability by the newer bios may have come from locking this value higher. I don't know if this is simply a glitch that occurs with v19 and my PC4800 TCCD ram or not, but thought it was worth mentioning.

I am getting decent enough results with my ram now that I think I will just give up on any magic bios revision fixing the 1T issue and the minor performance increase from 1T doesn't warrant me buying an entirely new motherboard. I also can't say that I have sworn off all future Abit products, but this experience may bias my opinion towards another manufacturer. That being said, I am still experiencing better luck with this board (aside from the 1T issue) than my previous DFI Ultra-D that would test stable for days using whatever stress test I tried (yeah I tried all from Memtest86+, infinite 3DMark01SE loops, long Prime95 and SuperPi runs, to software tools like S&M and OCCT) and then still randomly crash far more often during actual use than any of the stability tests suggested.

man i keep reading this so i've got to ask................who are you and why do you think you are so important that Abit would go out of your way to impress you.................don't you think you would at least be an Abit beta tester if they valued your opinion



1T works on any core if you have the right combo of RAM+mobo+CPU...........

well the fact issues were being fixed in the order i shunned abit for, plus my artical was right under their noses on google, then the fact i dont believe in coincidences to the degree they occurred when i got the artical going, go figure

and whoever asked, official and modded 19 are good, no real difference apart from the modded having unhidden options.

i can hit with my venice 280x10 and my BH5 1T , and for 24/7 i user 255x10 = 2550mhz and 1:1 BH5 255mhz cl2-2-2-5 1T ,and no problems , what kind of issue you gus talk about 1T ???

[socrilles]

hi all, just got the an8-sli and have a opteron 165, when I put the 165 in, it doesn't really fire up at all...do I need the latest bios to get the mobo to post, or is this probably a problem with the mobo? I ask because with my epox board it would post without dual core support and then I was able to flash to dual core support, but again the abit board gives me nothing

[Malichite]

mascaras, the issue that almost everyone is having with the AN8 is generally occurring at RAM timings above 260Mhz and exhibits itself in random reboots, shutdowns, and other general errors. Many report testing the exact same chip and memory in DFI motherboard and getting around 295-305 Mhz with 1T. I for one can achieve only achieve 1T at around 240-245Mhz with my PC4800 TCCD memory, anything higher and no luck regardless of any timing tweaks, aside from bumping it to 2T.

Doesn't really matter at this point though, while a few have had success with the AN8 the consensus seems to be "buy a different board from another manufacturer if you have TCCD memory unless you want to either run at lower Mhz RAM timings or CMD at 2T". If everything works for you, than be happy and don't mess with it! However for the rest of us with TCCD memory, it is clear that BIOS rev 19 is NOT the "magic bullet" to solve all problems.

the DFI ULTRA-D have the same issue?? my BH5 only do 255mhz but i can do it with 1T , id like to see TCCD in my board to see if i have the 1T issue , at least to 255mhz i can run 1T bit with more i dont know , i bought a opty 144 this week , and i was thinking to buy a TCCD , maybe i have to sell my board and buy the DFI ULTRA-D its better???

[Pedro69]

I just thought I join the club here . I just tried my first OC with my main rig and I have exact the same issues like most here. I can hit 250HTT but only with 2T and the system isn't stable (crashes in BF2) and I even hit 290 but only with one stick of my memory. I hope Abit comes up soon with a fix or I have to get another NF4 board.

[Gitsum]

Wow, I can't believe this thread is still going.
Ah crap, I just helped it along, didn't I?

[biatche]

Hello thread, you're now back to life.

My system won't boot up if:
FSB 280
Mem divider: 366
Cpu 280x8

but will boot up if

fsb 240.. all 1:1

my venice e6 will error out 250x10. seems stable at 240x10 but sometimes errors out when i occt/prime it..... (since i keep rebooting the box to try different settings... i only occt / prime max 30minutes)

is this normal? does e6 really suck to that extent?

im getting an opteron 146, any good feedback on this?

i also got two sticks of ram... my old Mushkin LVL2 PC3500 Gold..

and new PC4000 VX GOLD... man i can never get this ram stable, at 240 it is already trouble, in 10 hour test, ii'd get 1-2 errors.... sometimes alot... its so inconsistent..... how far can this ram go? i thought 250 2-2-2-8.... this just sucks.

also, my mushkin just can't do 1T.... whats up with this? is this the legendary 1t issue?

[bazzah]

u r lucky mine wont even hit that high, this board just doesn't like OCZ rams, I have PC4000 Gold VX(1GB) and PC4000 Gold (2GB UCCC), don't even think OCing on 1T; it only runs on 1T on 200MHz. chucking this board somewhere for backup only, no wonder Abit is going bankrupt (if u guys don't know, they have huge debt).

im on dfi eXpert now bye bye abit

[Zangetsu]

I have the regular an8 sli and currently i have my winchester 0451 @ 270x9 1.55Vs. Ram is KVR 3-3-3-8 1T on 166divider. Rock stable for me. Gonna try lowering the multi to 8 and htt to 312 and see what happens. Ram divider @ 133 of course. My kvr can't handle anything over 223Mhz.

[tictac]

Wow, this thread is still going
my bad....
1T no go...

[dinos22]

Wow, this thread is still going
my bad....
1T no go...

i got 1T going in the end heheheh but at that time i already got a DFI as well heheh

my key was just running G.Skill LE TCCD RAM....it ran awesome and even to this day all the CPUs i had OCd higher on my system than any other system even with better cooling.....Abit=good too bad they don't listen to customers very well

so did you get any board tictac

[tictac]

ya... but they didn't listen...
better play with DFI

[Rolle2k]

There is a Beta 20 bios out now with some new ram settings in it!
you can download it HERE.
HERE you have the thread about the bios in the Abit forum. Seems that 1T is fixed for some people at least.

My first Post

I'm using the official 19 Bios, since using mushkin XP Redline 4000 2x1GB (infineon ce-6) i dont have the 1t problem anymore at high fsb (above 250).
Before I tried OCZ Gold 2x512 (Bh5 UTT) and Corsair twinx XLPT (samsung TCCD) 2x512mb. I don't know, maybe the mobo doesnt like tccd or bh5??

[celemine1Gig]

Hi guys,

I had some time today, so I modded the new beta BIOS (AN8_20).

You can download the file here:

http://people.freenet.de/celemine1Gig/BIOS/AN820BM.BIN

The changelog is about the same as the one for my modded AN8_19 BIOS. So have a look at that for the changes.

The file is not tested yet(I don't have an AN8), so no guarantee from me. Use the file at your own risk! If it works, that's good, if not then I'm not the one to blame. Keep that in mind.

[tictac]

nice... thx

i have mod this version 20 as well... with preset:

tref timing
DQS strenght
DQS delay
drive strength

my friend said he got 2sec faster in super Pi 2M... he will be using it for competition... will let you know our progress later... wish us luck

HI tictac, could you send me that bios? I've been having some trouble to oc my G.Skill 2Gb HZ sticks.

Mail: pfgp76@gmail.com

Thanks

HI all

I wait this great bios for a long time !

I am having some problems with my old G.Skill PC4800 LA (2*512) : 290 Mhz 1:1 2.5 4 4 8 1T .
