Now my feet hurt, and it's your fault Abit... I don't need extra exercise runnin up n down stairs, so give us back our reset facility please!

cant they maybe make a BIOS update that will allow you to have a setting in BIOS to turn this "feature" on or off?

**vbhard** · 10-29-2002, 07:43 PM

the reset button for me doesn't work sometimes for me even at 177MHz

Also changing some of the simple settings say vdimm from 2.65 to 2.75 or vice versa system just hangs ..similar affect like the 'reset button'

Mine actually rebooted during playing BF1942 last night and since then it wont auto restart when selected leaving Windows.

I know we all hear problems people have with systems that will just random reboot, but I dont get those......until now. This board kinda has me worried, where Im used to enjoying my Abit boards.

And now with a few comparisons Ive seen between the 2.4B and the 2600+, Im thinking of switching back to Intel again for another run.

One of our local stores just posted availability of the 2600+ for $371 US and it gets beat by the Intel 2.4b which is only $221 US. So much for AMD being the powerful, cheap alternative.

Aha!!! Thank you that man!!

I was at a LAN this weekend, and installed BF1942... surprise surpise my machine crashed half way thru playing and now won't reset from Windows when told to... still haven't found a fix yet... I just wiped and reinstalled Windows...

I thank all of you for your input so far on this thread

Late last night our Abit contact called and he and I went over this entire thread, all info was noted and it will be relayed back to the engineers. Those of you who gave me detailed info and numbers, that was greatly appreciated also. He was unaware ,from his seat, of the heat and undervoltage problems...so this info in its detail was very beneficial. Your continued feedback on the KD7 and AT7Max 2, and for that matter, any of the performance boards members use is always welcome.

BTW....you guys running undervolted memory IT7's, that issue was passed along too.

After much testing here's the short list:

HD corruption at higher FSB speeds (seems to be right around 200mhz for most of the KD7 boards I've used).

Overstated system temps...no big deal really.

No reset over 180mhz is a real nuisance.

Sound crackling occurs on some games. Even when using a non creative card like my trusty TBSC. This indicates some PCI bus troubles. Note that the PCI Delay Transaction is Enabled by default in the BIOS. As setting enabling PCI Delay Transaction in the BIOS is the common way to cure sound crackles and HD corruption, it seems Abit is already aware of the issue.

Other issues...(which are really KT400 issues):

Only synchronous memory support when running the 5:2:1 divisor. Memory speed setting locks out at 166mhz when the 5:2:1 is slected. Some users are confused beleiving this means only synchronous memory support at FSB 166mhz or above. However, if you choose to overclock the AGP and PCI bus at 166mhz (or above) by choosing a 4:2:1 divisor you can then select the memory speed of 200mhz.

Very poor DDR400 performance when run asynchronously. Between the relaxed settings needed to keep the DDR400 stable and the latency penalties involved, asynchronous DDR400 is useless IMOHO.

Other comments:

Although I found one of the mounting holes to be close to some resistors (the north/right hole), I did not have to modify anything to fit Swiftech mounting hardware onto any of the mobos that have come through the lab. I'm wondering if this indicates manufacturing variances.

Mosfets do get hot. They have not caused any problems for me thus far. All KD7 systems have been able to Prime95 and loop 3DMark2001SE for at least 24 hours in a highly overvolted and overclocked stated (at or near 200mhz FSB with Core voltages at or well above 1.95v). However, there might be long term stability issues with such high temps.

12v rail voltages vary from board to board...again no stability issues. I think it has more to do with voltage sensor calibration than actual voltage variation.

Final comment, run with FSB and memory synchronous, this is a great mobo. Between the onboard sound and LAN, better voltage options, USB 2.0, AGP x8, and it's price...it is a good value. After getting the KD7 tweaked I have yet to have any unhappy customers. Only extreme overclockers looking for FSB speeds above 200mhz are those who will have issues.

Damn...I type too slow

**Tomcat84** · 10-30-2002, 05:01 AM

lol yup

**Tiribulus** · 10-30-2002, 05:12 AM

Still a lot of twiddling left to do, but overall I'm happy with mine. It let me overclock my 2400+ to 23 and change with relative ease, gave me 16789 in 3dmark (a 1500 point improvement so far), another 500 megs a second or so worth of memory bandwidth over my KR7 (shoot boys, twernt that long ago when 500 megs a second period was damn good) and besides all that the onboard lan and sound doesn't suck! especially the sound was a real eye opener to me. 1 million times better than I would have ever imagined. Haven't gotten sky high bus speeds, but could be something other than the board, like the 9700 Pro or half a dozen other things. I really think we've gotten spoiled to the point where if we can't accidentally get 250 fsb and a 400mhz oc on air with temps under 40 we feel cheated. That's not to say that I wouldn't always like more or that I have no complaints about the board, but maybe I just wasn't expecting as much as other people were. I do have to say that this and the AT7 Max I just put in my wife's machine really slurp up the juice. Lowest rails I've seen yet. Same parts different board, way lower.

**RacerX** · 10-30-2002, 06:08 PM

Hey guys been fighting the data corruption with my AT7 max2 also. After getting the corruption at 200 with my Xtremeddr PC3200 I decided to give my PC3500 a try. I'm now running at 202 stable and haven't tried higher, yet.

I did though format a seagate barracuda drive to for testing. I left it on the raid controller as a single drive. Only installed 40.71 drivers and directx 8.1. Running very stable at 205 without the corruption. Rebooted atleast 20 times and even played alittle N2002 without hiccups.

Thing I noticed is I needed 1.825v to get my XP1600 to run at 9x205(1840) where as I only 1.750 to run at 9.5x195(1862). I know I the higher the fsb the more voltage a chip needs to be stable but I thought this was kinda high.

Anyways here's a taste..........

**DesireToFire** · 10-30-2002, 08:04 PM

This thread has been a good read.
Ive found few problems with this board it seems to be extremley stable, In fact I havent experienced a single crash. I have yet to attempt any overclocking however.

There are only two issues that I have with this board one fairly unimportant and the other something I feel is more of an issue but should be fixable with a bios update.

1. They real choose a bad place for the System temp thermistor it makes the readings from it somewhat less usefull, but I can live with that no big deal, I guess you can use it to keep an eye on that particullarly hot area which may turn out to be more usefull than not.

2. Bus Parking/PCI issue, as per the previous post Ive found very ocassional sound crackling issues. I dont know if anyone reads the TecChannel(In German) http://www.tecchannel.de/hardware/1053/index.html
But basically the VT8235 now supports Bus Parking if enabled in the bios(perhaps a patch could do this) it should both improve pci performance and compatability, and quite possibly eliminate all remaining Via pci issues.

Id love to know if Abit plans to release an updated bios with this feature i really hope so.
Other than that Im extremely happy with this motherboard.

**ABIT Marketing** · 10-30-2002, 10:10 PM

Thank you so much for this thread Randi, really appreciated.
Just want to let you guys know that I have already summerized and forwarded this thread to our FAE in Taiwan and they are looking into the heat issue right now.

Dang I can't wait to upgrade mine too!

**TheDude** · 10-30-2002, 10:19 PM

Welcome to the forum!

Thanks so much for your concern and your help. Very impressive that Abit cares about and listens to, customers! When it's all said and done, that's what matters the most.

**ABIT Marketing** · 10-30-2002, 10:25 PM

Thank you for the warm Welcome TheDude.

Small update:
Just heard from my buddy over at OCZ regarding the data corruption issues. I sent him a couple KD7 for memory validation and he tested with their PC3200 and the 3500 and can not seem to reproduce the same problem.

I should have the results back from Cosairs as well by tomorrow. Gonna keep you guys updated

**twiggy** · 10-30-2002, 10:48 PM

wow its really nice to see a company that cares.

ABIT does own and u dont how much this means to so many of us overclockers.

**Marci** · 10-31-2002, 04:42 AM

I sent him a couple KD7 for memory validation and he tested with their PC3200 and the 3500 and can not seem to reproduce the same problem.

At what FSBs did they run the test, and with what OS?

Welcome to XS Forums d00d!

So that's... official Abit representation, official Chip-con representation... what other big companies can be pulled in to boost the shared knowledge of our `iccle collective o' clockers?!

Apparently I am now an Official Innovatek Representation (according to Innovatek, anyways! Was news to me, but apparently I have been Innovatek UK as far as they're concerned since the day we started selling it ... lol... they could've told me sooner!)

**RacerX** · 10-31-2002, 12:46 PM

Hey guys just received another KD7 raid ver.1.1. I have to say looks like I got a yummy piece of hardware.

Scores are low cause I didn't reformat, out the with AT7 max2 in with the KD7. Gonna go for 215. Be right back

Test all the question listed above, and see if they fixed anything.
heat, fsb currputions, temps etc..

edit:
i just bought a kx7-333, but if this mobo is fixed then i might look into it. ill probly upgrade to a 2600+ in dec so if this board unlocks multis then i might have to get it

**MrIcee** · 10-31-2002, 01:01 PM

Abit Marketing

You are very welcome my friend

Glad to see you back and chatting with our members. This means very much to Xtreme and it's members to have your ear in these issues that have cropped up and any in the future....a company who listens to it's customers is a company who will thrive from the ground up. We all appreciate your participation

Thanks for the update also, we look foward to hearing if Abit can possibly resolve some of these other issues

**RacerX** · 10-31-2002, 01:13 PM

Ok, I getting lots of IE errors at 215fsb and if I try to launch Sandra I get errors. My voltages seem alittle higher than my first KD7. My system temps seem to be the same.

I have gone through 2 AT7 Max2's and 2 KD7's. This is what I have come up with. Someone once mentioned here that ECS was making some of these higher end boards. This might hold true.

2 boards with the Yang. AN YA-4 lettering on the back get data corrupiton at 215fsb

2 boards with the Tean TN2 94v-0 lettering get corruption around 200fsb.

I'm getting more stable voltages with the Yang boards. Also both my KD7's were ver.1.1 and AT7 max2 ver.1.0

The Yang boards seem to handle the higher fsb better. Meaning the onboard lan atleast to me seems alittle faster.

One more note if you order a AT7 max2 you might not get the black PCB. They have gone to the yellow/gold color like the KD7's. I know of one individual that has the 1.1 and was quite upset. I'm going through the process of trading my AT7 max2 for his. Hope to have it by next week.

later.

**Tiribulus** · 10-31-2002, 01:22 PM

So what does this mean for us who got a rev 1.0 in the last 2 weeks?
Tiribulus

**mike.elmes** · 10-31-2002, 01:27 PM

I for one have just recieved a rev 1.1 but this board is a non-raid.
RacerX1, is your board raid??

**RacerX** · 10-31-2002, 02:15 PM

Yup, raid. Check the back of the board which board do you have, Yang or Tean?
