KD7-E initial impressions!

Welcome to Extreme joeyao:)

If you haven't already, make sure that you flash the BIOS to a newer version. I find C8 to be the best. It fixes the no boot problem when FSB speeds are above 180 or so.

It's hard to tell from your post what BIOS settings you are using which cause the mobo not to post. If it is high FSB settings, flashing the BIOS will help a lot. If it is other settings which are just not within the operating range of your hardware, then they only way to clear those settings is by trying to power on several times as Abit recommends, clearing the BIOS with the CMOS jumper, or trying to power on while pressing the "insert" key during the initial bootup.

Hi! Mike. My bios is c8, it is a little better than cs when booting(Thank you for your recommendation). The system work stably on FSB166, I change the multi from 5X to 8.5X(835mhz to 1.41G) for different use. Unchangeable on FSB166, the memory timing are the most aggressive. I think in the division -5:2:1, HD corruption should not exist and the core of the booting problem lies on the mobo not other devices. Have you suffered this booting problem on FSB166?
BTW, the sisoft sandra seem to misreport my PCI&AGP frequency...

I've had no problems booting at 166mhz at all. If you are having trouble with this make sure you are setting the divisor to 5:2:1. Also, make sure the CPU Command decode is set to normal.

what are u guys using for a NIC card? i wanna know which one can handle high FSB

Right now I'm running Linksys LNE 100TX ver 5.1 NICs in all my rigs. The one in my KD7-E handles FSB up to 206 fine using the 1/5 divisor. Not sure at speeds above that as my Radeon 9700 says no to anything higher.

Funny, somewhere between 206 and 208 my D-Link 530TX+ cr*ps out. I had it running fine at 210 on my KR7a.

Maybe it's time for a little network burnin, perhaps I'm not exercising the southbridge enough?

i have that NIC right now, so i guess i can use that

thanks guys

Hey guys, I finally got 3DMark to run over 190 fsb, though only slightly. I know now that it is my Radeon 9000 that is the cause. It just can't handle the higher fsb. I was able to complete 3DMark at 192 and hit my goal of 10k. I am third in AMD systems, only a mere 30-40 points behind a couple of nForce2 boards :) At 185 fsb the Radeon displayed no glitches what so ever, but once I hit 190 or above, it would start to show signs of stress even at the same or lower overclocks. I should have a Ti4200 here in a couple of weeks and we will see if I get the same type of problems, then we'll know if it's a shoddy agp port or truly the Radeon 9000.

Got a few more MHz outa my TBred and it was running stable, but ran out of time to do 3D at this speed.

I see some differences from board to board here... My board run 200mhz FSB all day long, Prime95, 3DMark, never crashes whatever you throw at it. Mike's board is also a very good one.

Now getting 215 FSB, 3dmark stable from my board. I'm running an ABIT GF4 Ti4200 (4X AGP, non OTES). Can't publish any score running 3dmark above 208 FSB though :(.

Anyway, after a little conditioning I think you'll be happy with the 4200, SPQQKY.

Wow...some good stuff going on now there:) I only wish I could get my board that high. Good job...I'm glad to see you got it sorted out.

Getting the Abit Ti4200 OTES. Might as well for the price (64 Megger), see if that GF FX type cooler will help at all.

The key (other than sorting out my board) for me was absolutely stable memory.

215 is my current 24 hour stable FSB on memtest86 and Prime95. I can bench Sandra as long as I wish at 220, but not 3dmark, Prime95 nor memtest86. As my TwinMOS burns in, *IF* I can get it Prime95 stable at higher FSB, it really feals like the video will be stable, as well.

Paraphrasing what you stated in your first post in this thread, this board is video card friendly, much more so than my kx7! So very true, mdzcpa, glad I got that advice from you! :toast:

Thanks for the toast...I'm glad I could help. I am certainly no expert in all things hardware, but I do find it very rewarding when I can offer some useful tid bits of experience to others when I stumble onto something good:)

you think it would help me if i bought a pci ata card, to reach higher fsb's?

might as well wait for the NF7 rev 2. ;)

I'm running a RocketRAID ATA 133 card and it does work very well with the KD7-E. However, I have never tried comparing the max FSB with and without the card. I originally picked up the card when I had my A7N8X. I really like IDE RAID which the A7N8X did not support.

That said, many users have found the ability to reach higher FSB speeds with PCI controllers...generally speaking.

yeah i get a pci raid card next week from a forum member (in switzerland :D ) well see how much this mobo makes

Cool...Looking forward to those results:)

sure i want to break 15k till now i have 14804 with the epox 8k3a+ @200mhz fsb and ti4200 308/650

Im at 15261 now, but i havent vmodded the mem yet, and have yet to try the core higher than 1.8v. Just sat the core on my Ti4200 to 332, mem 640. Havent uploaded it, im at a party!!

:toast:

This board and my TwinMOS just keep getting better. Sandra mem @226, 3dmark01 stable at 224. 3 volts to the memory so I still have room to push it as well. Nice and stable for video at 224. I'm from the gaming rig school of clocking so I'm sure I don't have the skills for mad bench scoring but this is really a fun board to work up!

very nice. i should have got a KD7-E no doubt, this KD7 wont even do over 180.

Wow...way to go sjohnson:) I wish my R9700 Pro allowed me to go higher. Too much trouble to swap out vid cards just to see.

Anyway, congrats on the awesome overclocks you're getting with the KD7-E:)

Thanks, what's really impressive to me is the continued high memory efficiency - that sandra score is at 97% of theoretical max. With the AGOIA 1600+ I could get 96%, this 1700+ JIUHB gives it that little "extra" :)
