This board is great but also not that great:

- can't hit high HTT... strange bios maybe.
- Vcore is overvolting ... sometimgs 0.1V

Nice :toast:

Hows that compare to your previuos baord (gigabyte wasnt it?)

I would really like to know if this board offers any overclocking improvement over say the gigabyte or shuttle. The BIOS & voltage options are nice but really un-necessary with A64 tweaker + volt mods. So come on and give me a good reason to buy one.

ok, u've a prommy....so, your results aren't valid :D :P ;)

but nice ;)

Thats pretty sweet, PC2700 too:D How much v is the Ram getting and 3.3 rail? But most importantly, is this via Clockgen or BIOS?

I dont know of any A64 board modded or not that will feed 4v vdimm which this one is supposed to do with beta BIOS and 3.3 rail mod. Thats a pretty good reason for me if it's a stable board. To me this board is catering specifically to the overclocker, so naturally it will take a little bit more knowledge to run it successfully. Still, I think you have a valid question. People are scoring big with the Gigabyte ala Macci and some of those Portugal guys. I think we need some time to see just what can be done with it.

If I didnt already have a S754 setup then this board would be my first choice, but seeing that I already have a pretty good AN50R its hard to justify the upgrade.

I keep telling myself that the AN50R is holding me back since I can only get 1.96V Vcore out of it and its an old NF3-150 chipset.

Convince me !!!!!!

My previous board was a EPoX 8KDAJ.
Well those extra mem timings in the bios is "A64 tweaker build-in" :) so thats true.

Compare to the shuttle....well thats difficult, the shuttle is a one-hell of a clocker.
The DFI NF3 is a lot more stable then the EPOX 8KDAJ. (ie. Vcore)

But i have the feeling that i can push more on the 8KDAJ then on the DFI.

So i think it will give you a more stable 24/7 rig, but not a good OC as your shuttle.

But im still searching why it is so hard the last 200MHz... (HTT? bios?)

btw.. The 2.1v bios is not working, seems it hit his own OVP?? :stick:

All through BIOS.3DMark works there also.Lot's of volts.3.5 via DDR Booster.The stick was bought fromn newegg as Buffalo PC3700 but SPD is 2700 I have a few nice ones.Had it up to 294x10 with 1x512 EB3500 at 3,3,3,9 but only Sandra stable.

Hi! i have a big problem on my DFI!

i flashed by winflash the 914 bios with 4v vdimm support. all worked well!
i cleared CMOS and now i have the following error:

"Bios ROM Checksum Failed"

it lets me go to DOS with a bootable floppy and flash the bios all over! the curious thing is that after i flash the original bios to the chip, i reboot and get the same error again!

any suggestions on what i could be doing wrong? i tried to clear CMOS after flashing and still nothing, always the same error.
09-19-2004, 04:26 PM
[SuPeRmAn]

thats a CMOS checksum error... i have a Bios ROM checksum error, but thanks anyway.

i believe ive gotten that be4, but honestly im not sure it it was a bios or cmos checksum..

but if you can get into the bios, then you gotta set it up.. mine errors with a checksum after every cmos reset.

well, i cant go into the bios, thats the problem...

:bleh:

brilliant. I know that OCZ has changed since then, but they still did it. I also understand if they send their best one to a reviewer, but if the review boards are getting 420HTT and the retail ones are getting 250HTT, thats just :banana::banana::banana::banana:ed up.

He also is a reviewer, dont be stupid.

My HTT is at 275 right now. And it doesn't mean it is the board either...it could be the CPU as well right?

Just because skilled overclockers get a beta board and get 425HT+ and modren overclockers can't, doesn't mean you gotta flame a Great Company. OCZ Has the best memory out, Who cares about there past. Mistakes only make you stronger, and Who has the best memory for the amd64 platform?

Don't call me stupid again.

That's my retailed MB, not a sample MB... ;)

If you are going to test higher HTT with a newcastle core A64, you will be disappointed, most got around 3xxMHz HTT, finished, but with a clawhammer, it is easy to get over 400HTT, though higher HTT with async. low freq. of RAM got almost no advantages.

If you only got 250HTT, there should be somethings wrong in the settings, apart from lowering the RAM freq. and CPU multiplier, try to set the LDT ratio (LDT/FSB frequency ratio) to AUTO, it is the best setting when you are playing high HTT, you may get boot problem if you set the ratio manually, e.g. 2X, 2.5X.......bugs.

You can then check by sandra to see what the actual ratio the BIOS has set for you...e.g. for 425HTT, the MB has set a ratio 2.5X for you (see attachment), i.e. 1062.5MHz Hypertransport!

LDT at 2.5 seems to work well for 250 plus, mem settings(all of them) seem to have big influence on getting high HTT speeds.

I am not going to bother with screenies but I have been up to 345HTT prime stable no problem. After this I start loosing my raid array, IDE drive would probably get me farther.

My board is a retail board with no mods, running beta bios with Vdimm mod.

Convince me !!!!!!

Just came from an AN50R myself.

I can't tell you much cause i haven't had much time to fiddle around w/ this board but the one thing i found is that the max of my CPU isn't any higher on this board, despite the higher Vcore options.

It was also a bit hard to set this board up properly, it had a few quirks but a fresh windows install ironed out most of it.

Also, the voltages appear to be jumping around a bit but i've been told this is a bug of the chip reading out the voltages.
On the Shuttle all voltages were always rockstable.

On a positive note, i've never gotten such high voltages so darn easy.
Vcore is already high enough and Vdimm is just a matter of flashing the bios, which is a walk in the park.
Now i'm no longer scared to raise Vdimm over 3.2V, doing this on the Shuttle made me nervous, as that board is a wellknown chipkiller.

Other advantages over the Shuttle are:
Wider Htt bus, 6 channel sound, working sata even with very high bus, loadsa bios options.

Maybe i can convince you later when i master all options and possibilities of this board. :D

hmm that make sense... ive got a NC 3400+

I hit 305MHz (AUTO HTT) with this boad.

http://www.xs4all.nl/~famchow/A64_34...305MHz_HTT.JPG

It crapt around 315-320Mhz.

But with the beta bios i cannot go beyond 280MHz.. then is looses the array.

hmm, yes could be, I hit 300, but its not completely stable.
http://users.pandora.be/lifeless/300HTT.JPG

But i cant seem to get my cpu over 2400mhz stable :(

andL64

so dont go for a newcastle? i cant believe i wanted above 3.0ghz with a necastle on water but i wouldnt do this with a clawhammer i think so should i go 4 a clawhammer because i get the mobo in a few days...

Thanks for that.

Keep us all posted.

It will be interesting to see whether or not the DFI vcore regulation is better than the shuttle and hence offer a better overclock. The extra HTT speed from the NF3-250 chipset is just a bonus, but it aint going to seriously help my 3dmark ;)

yeah RW Bypass 16x is faster... interesting about 32bit granularity
