I have a mach1 and it cant hold reset on this damn board! BS!
Anyhow Im running 3x256mb xms3500 rev1.1 at max Vdimm and default VDD. I defin. need more Vdimm, I can get upto 230 but mem starts to crap:(. In my NF7 I can do 230-240 with 3.3v. V-mod anyone? DDTung where are you? :D
Does you board have the trace cut too?
Yes.
Man Abit needs a BIOS that reads under 0c! I have no CPU temp lol even clocked at 2.7ghz.
In my nf7 I could boot at 3ghz with 2.3v but couldnt make it into windows. Maybe 2.313v will work if its not undervolting.;)
Is that DC on that An7? Also where do you get that CPU-Z program?Quote:

Very slight undervolt on the Vcore now. Like 2.134 is really 2.09
Not too bad.
But I'm impressed with your OC. What are cooling the NB with?
google itQuote:

Yeah I figured it'd undervolt at high vcore, my NF7 is like that, overvolts at anything under ~2.1v and starts to undervolt at 2.1v<.
Everything on my board is still stock.
Except the Vdimm is at 3.20 right?Quote:

Yeah, my voltages are 1.96v Vcore, 3.2v Vdimm and 1.6v Vdd.
EDIT: also the multi's still dont work for me.
Ok, here the reply from Abit about the cut trace. it WILL BE ALL the new boards too but not visible.
Cut Trace Answer
We have official word that the cut trace was necessary to correct a problem. Newer boards have the same fix.
The first lot of AN7 was with that trace cut; however, we have fully tested every piece of AN7 and all the functionalities are OK. Please ignore it as it in no way effects the board, infact it is a fix and needs to remain that way.
Please dont ask about what the specific problem was as I dont know and I am not going to ask for the schematics of the PCB layout and try to figure it out, just sufice it to say that all is well with that trace cut and future boards will not have it be visible.
Thanks

LOL, how did I know what they would say, very predictable....
Would have been nice to know what they screwed up:stick:
But they really side stepped the issue.
Like why wasn't it fixed so future boards don't have it?
Why wasn't the line chnaged after checking out a couple boards?
Are they saying they produce many of these boards before they check them out?
Is that why many boards in this industry suffer from poor quailty in many cases?
OK they replied.....
Well obviously the answer is that it over volted the 3rd VDIMM slot.. hehe hell i know since once again.. i connected it.

A dead slot does not indicate that it was to high of a voltage. only accurate way to diagnose is get a straight answer from Abit, trace the circuit on the board, or to look at the schematic...
Happy ThanksGiving to all my Oc'ing buddies whether you celibrate it or not :toast:
Ok, this is where I'm at right now.
I don't think this board likes BH5 chips that much or at least not my older KHX 3500 that are marked
"Kingston 4.5"
I thought all along they were BH5's but I'm having doubts now.
At least with this board. In other boards the stuff ran so so also
but best in my P4P800. I tried 4 sticks and all of them errored out in Prime at 221 and rebooted the system where the KHX 3500 CH5's ran just great in it. Again I stress that this was the ram the Abit techs used to check this board. I doubt they used BH5's.
The Buffalo 3200 BH5's have to be tested again. They also ran sos so *compared* to the Ch5.
Now, I'm Priming at 225 but with Interface disabled in the hope of burning in the NB this way for better future results.
I also wanted to take all the possible bottle necks that might cause errors while trying to take the FSB higher. So I though perhaps there is bad voltage regulation on the AN7, so I stuck my Hynix DDR500 in. It loves the Hynix ram for sure.
Now this ram is doing 225 at 2.60v I'm giving it 2.65v just to give it more edge. I mean it can do 275 at 1:1 so 225 1:1 is not big deal. heck I bet it can run at 2.55v but I haven't tested it that far yet.
Yes it's just Priming away here plus my CPU Mhz is improved.
I had it 227 but I think the ram kicked out or the higher Vdimm made the board unstable when using the other rams.. This is what I'm trying to find out.
I can tell you one thing, the system is running much smoother,
Whether it's the low Vdimm {probably} or the Hynix chips {don't know yet} or having Inrerface disabled I don't know yet either.
Too early to tell about any of them really.
But, with all that's happened, I will say if you get a working board and not expect miracles, plus you have knowlege about N2 boards, for $115 is makes a nice playtoy :cool:
Tech..
whats the diference between interface enabled ou disabled ?!
I still dont have a n2 board but i'll buy one for me :)
About 20 - 30 Mhz FSB worth in performance. You want to keep it enabled.Quote:

A pretty big difference in benchmarking scores.
I'm not too sure of how much a performance hit games actually take real time with CI disabled. But remember one thing in exchange for turning it off, you migt but able to take the fsb much higher making up for some of the loss and maybe also allowing lower latencies and response time.
It's a trade off. Hey, I'm into this business for fun 1st and to see higher number even if performance takes a hit LOL
I'm Xtremely brainwashed :alien:
:banana: :banana: :banana: :banana:
I have to put some cooling on the South Bridge. it gets super hot man. My finger hurt after I held it there for 3 sec. I felt cause I lost my USB mouse Priming at 227.
The keyboard, Prime, everything else worked OK except the mouse. Instead of trying a PS/2, I'm going to put a NB fan/sink on it first and see what happens. It used to work and my early NF7 versions.
so.. if i enable cpu interface im able to get mor fsb.. but i my "timmings" is higher ?!
No CPU Interface enabled gives you 20/30MHz FSB worth of performance due to faster timings but reduces potential overclocking speed on the FSB...
I.E. 200MHz with CPU Interface ON will probably equal 220MHz with CPU Interface OFF.
So keep it on, it's fastest :D
strange.. my friend have nf7s and he told me that his nf7s get more oc with CI Enabled...
but.. i dont know if he hasnt changed another thing at the same time...
That's pretty unlikely NoOne.Quote:

You'll get better scores but not higher FSB with CI enabled.
I just read through the entire thread.
Pity the boards that you guys have tested aren't obviously better than the NF2 v2...:(
Cause I would have really liked a board that would have allowed me to bench at 12.5 x 244 or there abouts.. :) On the NF7v2 in my possession it's 13x 234 or there abouts as a max 3Dmark HexusPifast stable.
The same board was doing 250 x 11.5 with CI enabled. 252 as a max. With a different cpu.
