I've been away for the past 3 weeks.....just installed the 1.07d bios and will do a performance comparison between the 1.04a and 1.07d bios. I'll post my results later this week.....

My Prime temps....highest achieved as it does fluctuate depending on what test it's running.....is 46C with a 72F room temp.

Oh and BTW I'm a HE

So you finally make an appearance Gives us the skinny as you seem to have the most stable oc, and we can all benefit from the results.

I have tried the new bios and it does not seem to make a difference. I am really starting to think that there is a problem with the cmos clearing function as even when I clear the bios comes back with some of the old settings that are not default.

For the benefit of any Aopen reps who happen to do a little market research . . . up the damn vdimm in the next bios revision so we can oc the new DDR modules . . . restrictions on vdimm when current modules are rated between 2.5-3.1 is ludicrous, not to mention the fact that you include vcore adjustments that far exceed the specs for the P4, but undervolt power hungry ram. . . Wtf

Sorry, as you can see I am frustrated, and Aopen doesn't seem to want to allow me to register on their forum.

I am curious as to the change in the DDR voltage selection. Does that mean that you can no longer manual set voltage and that AUTO is the only setting, or that they fixed some bug with the AUTO setting. Oh well, guess I can try it out to see.

Update, it appears that the problem is with something other than my mem, as I purchsed some mushkin for another system and tried it out with same results as the Geil, to similar in respect to the errors. Moreover, I did a doc mem test on the Geil Dragon mem at it came out clean after 12 hours of testing at 440. This means I am going to have to eat crow on those forums that I dissed the Geil mem.

Looks like I will be tearing down and rebuilding this weekend to trouble shoot. Ah the joy of configuring a new system

Man I will tell you that I have never had to eat crow more than I am doing with this board.

It appears that my remarks were again in haste as I failed to change the settings in the bios after installing the mushkin mem. It appears that I was wrong in that it was a mem problem because I am now able to run a FSB 255 stable with this board with mem @2-2-2-5 timings and 1.60 ratio VDIMM @ 2.75. I owe Aopen an apology for being a little hasty in my remarks, but I will have to say that my confidence in docmem as a reliable mem test has depreciated. Well at least I don't have to retrack my remarks concerning Geil, even though it may either be a bad chip or just a compatibility issue. I think I will be less inclined to post to these threads so quickly.

Any way I was only able to fool around with it a little this past evening and will post all of my benchmark scores later, but I will say that the Mushkin Level II mem rocks. I was able to get to a 220 FSB @2-2-2-5 no prob at 1:1, then I got impatient and switched to the 1.60 settings so I could see if it would run stable at the above higher settings. Go figure

All of the probs with prior bios seem to have been fixed and the results obtained by Shoman are consistent with what I have been able to achieve, except mine are little higher. Mem bandwidth its just a tad under 6 gigs.

Any way Sorry Aopen and good job on bios, now if you can jsut fix the utilitties, there will be nothing to complain about this board.

I had a shock this morning when I switched my computer on, it wouldnt boot. The screen came up with the message


Award BootBlock Bios v1.0

Copyright (c) 2000, Award Software Inc

Bios Rom Checksum error

Detecting Floppy drive A media

INSERT SYSTEM DISK AND PRESS ENTER


I've never seen this before and didnt have a clue what it was. then I noticed it said BootBlock Bios and thought I had a virus and it corrupted my bios. I thought no problem I'll just recover it from the rescue bios, tried it and no effect, didnt work, same message came up. Thought I was in real trouble now, i didnt want to lose everything on my computer. But a thought in my mind this would give me an excuse to get the Abit board. I managed to get the normal boot up screen appear by disconnecting the power and tried to get into the bios but the screen would just go blank. Then I tired clearing the cmos manually as it was the only thing I haven't tried and to my relief the system booted up as normal!

The only thing I did the day before was to set my memory to 2-2-2-5, my computer is not overclocked at the moment as the weather is a bit hot. I have good memory and seeing other people on this board setting there memory to that speed I thought it would be okay and it was all last night. By the way I am using the latest bios v1.1

Don't understand why the cmos didn't reset itself automatically when it didn't boot the first time, all the other bios did it so that you wouldn't need to reset the bios manually on the board. I'm also suprised that changing to the rescue bios didn't help, suppost thats not the purpose of this problem.

Well if you get this message appearing, you know what to do.

Also I don't understand how some people can get upto 250fsb on this board, I can't it stable over 240, any tips?

Duncan...I had an issue like that when I updated to the 1.07d bios and the rescue bios worked for me...then I reflashed it and am now back on the main bios chip and now running 1.10.
I backed down my overclock a bit to be 110% stable also lowering my CPU voltage to 1.65v in bios. I'm running at 242fsb 1.6 ratio ddr voltage at Auto, CAS2,5,2,2

I think the early 2.8's are junk. I got an early one as you did I'm sure....they have a hard time to do over 3.4ghz. I learned my leason about getting things right when they are released. I paid 400 dollars for this 2.8...also I'm stuck with an Abit IS7 that I tried once and had to RMA it. I should have never bought it. Now I figured I'd use it on a media PC and NOONE has an ATX case available that would fit in my entertainment rack yet. *sigh* Money, money, money....

BTW - Either the new bios or the mem I installed has fixed the EZClocking utility. Its now fully functional and isn,t bad as well as the rest of utilities with the exception of winbios that doesn't work with the new 1.10. HAven't checked this morning to see if it has been updated.

Haven't gotten around to playing with it because work calls, but it appears that the 1.10 fixes have done it.


I have had the same boot problem as a result of setting my mem timings to the tightest, on the Geil not the Mushkin, and all I had to do was powerdown clear cmos and reboot. The screen you see is normally associated with a corrupt bios. Its looking for you to put in a disk with the flash and bios file on it to reflash. Strange, but not uncomon.

I was fortunate enough to also buy a 2.8c that was of a later version and it has proved to be an excellant, but I now think that the 2.4c is a better buy as I have seen as high or higher oc's that alsao allow you to max out the DDR because of the lower multiplier.

"Also I don't understand how some people can get upto 250fsb on this board, I can't it stable over 240, any tips?"

You also have to realize that Shoman is using an slk with a hell of a fan on it and I am using water cooling to get to the 250FSB. Others with vapor cooling are getting oc's in the 3.7's with the same processor, so I would say that your 240 with a Zalman is damn good, especially considering the noise you don't have to suffer, and the worry you don't have about leaks like me.

Plus, as Shoman has said he has dropped down his FSB, which I will do also once I see what it can do. OCing is mostly to see how fast the car can run, not try and run it at top speed all of the time. A difference of 5-8 mhz makes no real world difference, its just trying to eek out every last mhz until you take your system right to the edge thats kinda fun. Sucks when you have to go through pains of trouble shooting like you can see portrayed in my posts, but sometimes it is the luck of the draw as far as processor, ram, et al. Plus I don't know what you consider stable, but I myself simply run Prime95 torture test for about 9 to 10 hours before I declare my system stable, most that actually use prime for its intended use run torture test x 2, by creating a seperate folder and running simultaneously at 1024k setting for about 24 hours to ensure accuracy (this is way overkill from my view point, but if your using Prime95 client it makes sense). Reviews usually run Prime95 plus another benchmark for 24 hours before they declare an OC stable. In truth, Prime95 is overkill, as there are very few programs that tax your system or require the accuracy that Prime95 does, or the others like seti@home; folding@home, et al. A practical stability test is to loop 3DMark for an hour or so and see if it crashes and then run Sandra burn in for a 12 hour period, if neither crashes then you are probably as stable as you will ever need to be.

242 FSB Shoman?

What's the highest this board can go on o/c the FSB? It seems like most everyone get 252FSB tops. I could be wrong.
Does this board supports the new Prescott?

FSB 252 is probably tops for most 2.8c's as the cpu tops out at about that. I was able to get a 255 FSB, but no higher, with a 1.75 VCORE setting (won't go any higher as I am afraid of frying my cpu). There was a roundup where the AX4C utilizing the 1.04a beta biso topped out at 266 FSB with a 2.4c, but the round-up also reported the board had heat dissipation problems and had the MSI board topping out at about 254FSB, if my memory serves me correctly.

A lot of talk about which boards will or will not support Prescott. The only board that I know whihc officially has stated that it will definitely support prescott is the new Abit IC7-G MaxIII. Intel is playing games again.

Look here. http://www.overclockers.com/articles777/

I sure wish AMD would get back into the game

But the odd thing is that Abit never specifically says that the Max3 will support the Prescott processors in its actual site. In fact, the only motherboard manufacturer that actually still says that they're motherboard will support the Prescott is Asus with their P4C800-E motherboards.

But even then I have my doubts. I actually waited to buy a Canterwood thinking that all of these mobos would support the next family of processors as everyone had originally thought but now with all this new info and/or bad rumors that none will support the initial batch because of power specifications, I think I waited in vain (well, at least it supports 800Mhz Northwoods).

To tell you the truth, I wouldn't buy any Canterwood motherboards out now on the ONLY basis that it says it will support the Prescotts until the Prescotts actually come out and it is proven.

Yeah, I looked at the web site and your right, my bad, I was relying upon an article that was written about the new colling apparatus on the Max 3 and it seemed to indicate that the new cooling was in anticipation of the Prescott running hot and the need for additional cooling around the capacitors. If the Canterwood and Springdale do not support the upcoming Prescott I think that we can expect to see some lawsuits flying soon.

Well this thread seems to have died. Well the new revision to the BIOS seems to have eliminated most of my probs with this board. Settled for a nice 251 FSB OC @ 1.6 divider, as I started having probs with the sound system, a little to high I think for the realtek and the southbridge. Had to overvolt somewhat, but not much at 1.725 my cpu should last at least 2 years even at that as real is about 1.65-1.68, and I will probably change out within next year and put it in one of my work puters. Not a bad board all in all, and for the price a much better bargain than the others. Still wihs they would increase ram voltage though

LOL! No Kidding!! BTW, that's an excellent overclock.....for a watercooled system. What are you running Vdimm and Vagp at? Did you make any modifications to the chipset cooler also??

Thanks, VDIMM @ 2.8; AGP @ 1.6; Chipset also water cooled (I credit this being the reason for the good oc with this board, in addition to having a 92mm fan blowing directly on the board, and that heat sink hanign there), had to make my own damn mounting bracket since the mobos with the 875 have those damn loops, but its not bad for the board, decent for the cpu as I have seen better oc's with the D1.

Ran into some weird probs with the audio, and had to birng it back down to the 251 (250 setting in bios) to keep it from going dead on me. I think the problems with the 875 relate to the power issues, and heat dispensation. I think this is the reason that Abit dsid their little dew with the cooling of the capacitors.
