Abit NF7 owners - BIOS option questions ...

ooo man ... it's back

107 bucks at newegg

I can't help thinking that I could get some serious performance with my ...

Xp2600 - (runs 189.4 easy on my KT333)
XMS PC3200c2 (runs 386fsb at 2.65v at 1T easy)
9700pro (runs 4x94 FSB also .. wonder what 8x would do with the Dual DDR???)

and got my modified Enermax 465 too

Is there switch or BIOS option to disable the sound ????
(got my own digital sound card)
 
Thanks ...

But .. I just downloaded the manual ... it says .. the PCI is not locked ... and of course ... it warns of running PCI cards out of spec.
(please tell me I'm wrong or if theres a BIOS update for this)

But ... there IS a AGP lock at 1mhz intervals ... (nice)
It also offers a whole bunch of CPU to MEM divider options ... (wow)

And unfortunately .. the memory options are minimal. (no comand rate 1T)

But I dont think I could run 1T at 200+ fsb anyways .. so .. (up to 237fsb)

I also read the that 1.1 version of the MB are out also ... with orange color and HSF mounting holes and the latest 1.3 bios.

I think I'm going for it ... 🙂
 
noid, confirm that newegg is shipping NV7-S with version 1.1. mine just arrived today and it is the new version. reddish-orange PCB looks very nice, the mounting holes around the socket are present (i use a clip HSF, the AX-7, so i really didn't care about that) and the BIOS has got tons and tons of tweaks.

just so you know, i dropped my Crucial PC2100 mem and a tbred 1700+ i got for $50 in this board. first thing i did was set the FSB to 166 MHz and the FSB ratio to 5/5 and DIDN'T CHANGE THE VOLTAGE, and so far it is kicking ass and taking names. =)
 
I just found out the only differences in the 1.1 version is the HSF holes and it's color.
It's still has the memory controller problems and the issue with the xp2600.
(the memory controller wont allow a boot with PC3200c2 timings... you have to use PC2100 to get the intial boot ,,,
Then set the aggressive timings and shutdown and swap the PC3200c2 back in.)

I'ts not for sure if a another version of this MB is comming ... but I'm going to wait and watch for awhile...


OH ... Can anyone confirm that the FSB adjustments are NOT in 1mhz increments?

And ... is there an Abit insider around here that can confirm a revision 2.0 comming???
 
noid, the BIOS does come in 1 MHz.... sort of. it is skips around a bit, going from 133 to 134 to 135, but sometimes it goes by increments of 2, like from 166 to 168. i am not a serious overclockers, but i am very pleased with my 1700+ hitting 1830 MHz (11 x 166) with PC2100 memory and default voltages. temps on the chip are still under 50*C and i don't even have all the case fans on =)

oh yeah, there is a dearth of fan headers (only 3) and they are placed in the most assinine place possible--right by the IO backplate. there is no header near where the front of your case is, so i am going to have to crack out the soldering iron and wire and length my front case fans.
 
Yoda ... thanks for you reply and insight...

Can I add a bit of advice ??

Case fans powered by the MB is a bad practice. You should get some Molar connectors to the 12v PS leads.
They have passthru molars so you still can attach other 12v devices.

The only fans used by the MB should be modified Vid card fans or northbridge fan and of course the HSF PCU unit.

Can you confirm the higher FSB settings (around 200 and higher) have larger gaps in the fsb sttings?

 
But .. I just downloaded the manual ... it says .. the PCI is not locked ... and of course ... it warns of running PCI cards out of spec.

The PCI bus is locked at 33MHz. I just dowloaded the manual from here =>

ftp://202.168.194.114/pub/download/fae/NF7_3in1_EngWEBV.100.pdf

And I can't find the text "the PCI is not locked".

Abit did not include a visual PCI lock in the BIOS because they didn't wan't people playing with a dangerous BIOS setting and it gives virtually no performance gain.

Abit's official word.

Should also note that folks are running exceptionally high FSB speeds (greater than 400MHz DDR) on the Abit NF7 boards without problems.
 
Page 2-3 ....

This motherboard supports standard bus speeds of 66, 100, 133MHz that are used by specific PCI, processor and chipset specifications. Exceeding these standard bus speeds is not guaranteed due to specific component specifications.
Click to expand...

Can you tell me where is says that is IS locked???

IN the MANUAL ??? ... Or from another source other than a forum post?

Can anyone verify for me thru Sandra that the PCI is running 33MHz while using a FSB over 166?

(Preferablely around 200 fsb)

Noid, that's not any ordinary forum. That's the Abit forum. And that's Abit responding to the question. That document ya quoted is most certainly out-of-date because notice it does not say anything about supporting 166MHz bus speed. Which NF7 certainly does.
 
please stop the full quote crap ... I dont want a huge thread ... thanks ..

I want someone to verify ... thats alll ....

Im NOT arguing with you or anyone ...I just want facts...

And ... as you see ... I was correct about the manual ... right?

I don't have Sandra, but I can tell you that the PCI bus independent of the FSB. I'm running the FSB at 192 x 11, overclocking my 2100+ to 2600+ specs. The only "dividers" to worry about are the FSB DRAM ratios. I'm synching (one-to-one) so my DDR is at 384 Mhz, which isn't even working up a sweat for my PC3200 DDR.

Can you confirm the higher FSB settings (around 200 and higher) have larger gaps in the fsb sttings?
Click to expand...
Right now, I can only confirm that the settings around 190 do not have gaps. I'm at school, and the 'puter is at home, so I cannot say specifically about 200 and higher. If nobody has answered, I'll try to remember to check it out this evening when I get home.
 
lol.. this is getting funny now...

Ive been asking in a few forums ... no one will verify... I wonder why

How can you tell the PCI is independent of the CPU and MEM divider without a utility program?

I have my suspitions because some of the dividers are ... 5/5... 6/6 which is in reality 1:1

Dont they know math? (just kidding) 🙂

Thanks blcjr

Did you actually even bother to read the link to the abit forum that was posted above? It contains a post from the forum administrator, an abit representative, to wit:

Well I guess it's too late but I just received a reply back from our FAE in Taiwan.

The PCI clock and the CPU clock are independent for the nForce 2 chipset, therefore the PCI will stay at 33Mhz for the whole time.

How much more verification do you want?

 
lol.. thats funny ... ya .. I know ... thats a 'representive' of ABit

funny ... how a representive needed to ask another representative ...

I very cautious on my MB purchases (yes paranoid and frugal) ... I've been burned before...

... and I dont like sending equipement back and forth, waiting for equipment, paying for shipping and going to the post office
... talking to techs that have English as a 2nd or 3rd language....

I could probably think of a few more ... ... how about .... ummm ... someone verifying the dividers and the PCI fsb...

... with a piece of free software... someone will reply ... with the same curiousity as me ...

dont you think the 5/5 and 6/6 dividers are fishy? arent you curious if they do the same thing?

________________________ EDIT __________________

I just found out Sandra is unable to /or is not configured ,,, to display the PCI frequency for the NFORCE.

I find this info odd also ...

No need for anyone to reply ... unless you found a utility that displays these specifications.
(then please PM me)

I still like to know the FSB increments over 200fsb though ...

Thanks all
 
Can I do what you want with the free version of Sandra? If so, I'll download it and check it out when I get home (late).

As for the 5/5 and 6/6, yes, they just sync FSB and DRAM. That I can affirm from first hand experience. I've booted into the BIOS and fiddled with these settings no less than 50 or 60 times since I got my new 2100+ T-bred B on Friday. It was my first experience with this type of "divider", and I tried out a lot of the 3/4, 4/4, 4/5, and so on cause I wasn't really sure what they were doing. But I soon caught on, because I knew what I was setting the FSB at, and the BIOS reports my memory speed during boot. So I learned that 5/5 and 6/6 were the same thing, that it would simply sync the memory bus to the FSB.

Why did they do it? They're from Taiwan, so how do know? 😕 (Actually, "some of my best friends are Taiwanese." Or were. I actually lived there for 18 months 40 years ago. There weren't no mobo manufacturers back then. There wasn't much of anything, back then.)

Well, I think you are being unreasonably obtuse (picture "Shawshank Redemption" here, if you can), but I'll continue a bit longer to try to help out. I enjoy a challenge.
 
blcjr ... dont bother on my account ...
...the Sandra PCI freq doesnt work on the NFORCE chipset ...
(works for Via and AMD)

It still has usefull utilities thou ... you might like it.

Let me know what those FSB increments over 200 are .. ok ???

talk to ya later

KidChaos...

Thats a kewl gizmo there... thanks for the link
 
Newegg just Ed me ... its back

One more question ... can the on-board sound be disabled ???

(I have my own digital output card)

______ Edit ..

opps ... its a BIOS option ... thanks!
 
ya ..... that's what I wanted to hear ...

Thanks LED 🙂

Hey ... you got a link for me to watch for the release info?

uh oh ... post # 500 ...

Am I spending to much time here ..??? 😱
 
thanks for your "advice" about the fan headers. i use the fan headers because i run ultraquiet panaflo fans and i like to view their speed and even throttle their speed down with software (program called speedfan) if they are running too loud. i used to be a hardcore OCer with delta fan this and 120mm case fan that, but that is all in the past. now i like em dead-silent, but i still like to push to chips a little.

this setup is perfect--quiet as a mouse fart and still a decent overclock (1700+ to 2200+ and the 166MHz FSB with old PC2100 mem). to each his own noid =)
 
yoda ,,

I had no intentions of offending you ... I know that case fans will affect stability of an OC if attached to the mb in some situations.
