I got me a NF7 Rev 1.2 Today

**OPPAINTER** · 03-01-2003, 09:56 PM

Heres my mem mod, no touching the pin 19 for this one. I used a 10ohm resister, then attached a 100ohm VR (green) to it.

Great Work OPP!

You always get there first, and give us all the low down... Thanks man.

If you can't get the 3rd dimm working, this effectively lets out Dual Channel @ high FSB, Correct? How much of an effect would this have in real world performance, and programs like PiFast that emulate it? And People seem to be saying that the NB is not getting that hot... How is your temps there?

I should have my 1.2 by Wed... Try'ed as hard as I Could but I was not able to lay my hands on one before then.

Best, RoydRage

**OPPAINTER** · 03-01-2003, 10:38 PM

The NB is pretty cool actually. Not sure whay the Dimm 3 is so tough. I can get about 233 with it.
I don't know about real world, 3d mark 2001 takes a hit though. I think it's pretty fast at 237 single channel myself, seems so anyway

Don't mean to jack the thread, but got a question about NB cooling for when I get my NF7-S...

I have water right now, but it's on the same line as my GPU w/ 80W pelt... I'm thinking of switching to just air. On my 8RDA+ it seems that the NB sits at 31-32 degress in BIOS... Is that good or bad? Can I get lower with air?

Now I was looking at a few things:
1. Zalman ZMNB32J
OR
Zalman ZMNB32
OR
NB MAXX Blue Anondized Northbridge Cooler
With
Sunon 40x40x20mm Fan
2. Stock NF7 cooler
OR
PCToys ICEChip (just about same thing as NF7 stock cooling)

Eventually, after I get my soldering iron and a pelt PSU (probably a meanwell) I may put an 80W Pelt on the NB just for the hell of it.

Also, anyone cooling their southbridge? I'll probably end up sticking the stock hsf on the sb like I did with my 8RDA+.

Looking good though guys, can't wait to get my NF7! Opp, I wanna see you hit 237 Dual Channel!

Been there done that on the rev1, only problem is that I could only use the 11 and 11.5 multiplier.
Timings were at 7-2-2 Cas2.5

Got a mem bench, Opp? And what do you think about the NB cooling?

Svenn, I've got One of these on my NB and one on the SB of my 8RDA+. the Sunon 40X20's I have are vapo bearing 10cfm about 6000rpm. Seems to do the trick though

**xtreme** · 03-02-2003, 04:13 AM

mhmm what changed for vdimm mod on rev 1.2 ? is this pic above for rev 1.2 ? and how do you attached the 10ohm resistor on this little leg ? ^^ and how do you attached the VR on the 10ohm resistor ?... sorry for the questions, but im a newb

Does lowering the Row-active Delay actually help very much? I can't see any difference in bandwidth between 7-2-2-2 and 5-2-2-2 in either Sandra 2003 buffered or Memtest86 unbuffered tests.

**Major** · 03-02-2003, 04:16 AM

yep 1.2, dont have unsoldier or cut pin 19 now, they put a resister btween pin 19 and mosfet so you can just soldier to pad now

**xtreme** · 03-02-2003, 04:23 AM

hm but opp said, he didn't touch pin 19

**Major** · 03-02-2003, 04:27 AM

right dont have to do anything to pin 19 now just soldier to the pad of the resistor they put between pin 19 and the mosfet leg looks like they did the same thing Opp did in his mod to begin with.

Edit I think i remember him saying he took the resisor off the board and replaced used a 10 ohm in his v1.2 mod.

It helps in 3D mark 2001 benching.

238 x what multiplier?

seems faster than 8RDA here
i can get the POS to 241 in single(240 in bios)

OPP can you make us a lil guide on vmem and vdd mods for the nf7-s 1.2? i should get mine next week, and i wanna buy the parts needed for the vmod so i can use her right away.

**Major** · 03-02-2003, 10:05 AM

Really need a sticky for all the different mods on the different versions of the NF7-S, sorta hard to find.

**mdzcpa** · 03-02-2003, 10:18 AM

Wow...OPP great work. 3-2-2 CAS 2 at 237 is sweet.

Well, you guys have convinced me....I'm off to radio shack for the modding supplies

**Creative** · 03-02-2003, 04:23 PM

I cant get 217 stable atm in my 1.2 board.

It will prime and then all of a sudden it will freeze, then 10 seconds later return, with it in 4 colours and saying that a Devie Failed and i must restart. I restart and all is fine?

I also am very annoyed at the jumps in the fsb range above 210....I might flash the bios again.

Better board than the Epox but nothing spectacular imo.....1 died after 4 hours so they cant be THAT great

A few thoughts:

Is it possible that you might be near the end of the rope with that 3200 memory. Running 400mhz memory at 434mhz could be the problem.

BTW, those FSB "jumps" are the way it is supposed to be. The clock generator used by Abit has those choices. A flash will not help....unless it is to a new BIOS that Abit manages to unlock a few other FSb choices (which is not likely)

**OPPAINTER** · 03-02-2003, 11:25 PM

Running two sticks solid at 238 in dimms 1-2, I had to change the Cas to 2.5 for the two sticks. I can't get Dimm3 any more then 230 solid and at very low timings. I guess I'll go to a pelt tomorrow and see If I can get Dimm 3 working better.

OPP

2 x Kingston HyperX at 3-2-2 Cas2.5

**Merenfreak** · 03-03-2003, 04:32 AM

Opp

Any difference of the highest CPU clock compared to 8RDA+ ?

thx n`cya

Very nice OPP

This is encouraging. I'll be doing the vdd mod once I get the Nb water cooled.

Keep up the good work

I should update my sig, Im running Dual Channel HyperX atm, 256meg sticks with blue heatspreaders so they are 434 sticks

Good summary on the fsb jumps but they still annoy me.....iirc someone on this forum said they had ALL fsb options, and no jumps, thats why I am thinking theres something wrong

Someone on iirc is pulling you leg than

I find the jumps to be pretty darn inconvenient too....but unfortunately that's just a limitation of the board.

EDIT- what did I just say
