Thanks for your help with all that, Tony.

You'll love the 1.2 NF7-S in the Mean Machine.

Wx,

I'm sure I will whenever I get one

You're Welcome on the PSU.... You know the old saying... "Buy The Best", "You'll Never Be Dissapointed".

You may want to try Azzo, Tony - (where I snagged mine and they were great making sure I got the right revision of the mobo), or I think Excaliber is supposed to be getting another shipment this week.

Most noticeable change I noticed between the A7N8X / 8RDA+ and this board is definately the weight. The 1.2 feels much heavier. Perhaps its a higher PCB layer count?

**twiggy** · 03-01-2003, 03:26 PM

OPP where you at?! Hows it going.

**fibonaccov** · 03-01-2003, 03:37 PM

mdzcpa,

I realize what you got is great - btw, you had to mod your cpu if I recall, no? The 1.2 seems like a good board indeed but it seems like a VDD mod is still required to go above 220'ish fully stable...like I said some 8rda+'s are running 230fsb dual-sync stable with and without VDD mods...Obviously, having a VDD of 1.7v in bios helps - I just wished they has made it available to higher values like the 8rGa+ ...I'm also looking at this board and will wait for more feedback...

Yep...sure did....but that CPU mod helps on just about all NF2 boards. This has been very well documented around the net by now

The 1.2 seems like a good board indeed but it seems like a VDD mod is still required to go above 220'ish fully stable...like I said some 8rda+'s are running 230fsb dual-sync stable with and without VDD mods...

Yep...but we both know that that kind of performance is the very remote exception....is it not? Most 8RDA+ boards run much much lower I thought. At this point only a handful of NF7 1.2 boards are out there so it's really too early to tell whether we'll see some 230mhz v1.2s. I expect we will.

The point isn't to look at the highest performers from each brand...nor the lowest. The best board, in my opinion of course, is NOT the one that has a very slim chance of running the highest FSB. Instead, the best board is the one that consistently puts many users in the highest range of stable FSB speeds.

Just based on the early results of myself (2 boards now that run 220s), MrLavender, Equito, Shadco, RacerX, a others, it seems running at least 217 is almost a given. I think you'd be hard pressed to say this of the 8RDA+.

But...perhaps I'm wrong. Perhaps the two 8RDA+ boards I tried were just bad examples of the board, and that the two NF7 1.2s I've tried are great performance flukes. You never know

Either way...I'm not going to get into a pissing match about which board is better on this thread...at least not any longer that is

If I recall, this was meant to be an NF7-S 1.2 thread I think...that is until some users decided to bring the 8RDA+ into the discussion

Sorry about crappin on your thread OPP

How about everyone else?

A3 here.

**xgman** · 03-01-2003, 07:09 PM

Op, what vdd are you planning to run at after mod? I have mine set at 1.85 so far and I am wondering if she will benefit from more?

**Major** · 03-01-2003, 07:19 PM

I think that 1.8-1.9v are optimal, just burned mine nb up at 2.1v with no gain after 1.9v, might have been my fault though, not sure if the water block was making good contact with the NB. You should make sure you have better cooling on the nb if your going to crank it up. Some people have reported getting better fsb just by improving cooling so you might want to try that first.

**OPPAINTER** · 03-01-2003, 09:05 PM

I did a little moding, I’m on straight water for the NB. This mobo needs more Volts then the Rev1.
I ran into a snag, the Dimm 3 sucks, and that’s the one I need for good dual channel. I can run all day stable at 237 one stick, and check out these timings 3-2-2 Cas2

That’s right, completely loaded a new OS and everything at these settings. The problem is, Dimm 1 and 2 work fine at 237 then I switch the stick to Dimm 3 and no go, Urhh.
My voltage is 1.96 VDD, and 3.1 v-mem.

I may have to resort to a pelt and up the VDD to get the Dimm 3 working at 237.

By the way, I did a mem mod, very easy on this Rev1.2 J the reason that everybodies mem voltage is over volted, is because Abit took our mem mod and did one themselves to this mobo

, right off of pin 19 they suck a resistor in the trace to the Mosfet, there’s your extra voltage

And this my friends makes for a easy break in the trace for us, just take out the resister and put in your own

OPP

**twiggy** · 03-01-2003, 09:09 PM

Sorry to hear that Major

. It took ~1.97v on my chipset to get 237 fsb and this was with the stock hs and no as3.

**Emericana** · 03-01-2003, 09:15 PM

opp lets see some sandra benchies w/ 3-2-2-2 at 237! kick ass!

**twiggy** · 03-01-2003, 09:17 PM

OPP- Yeah I noticed that this thing loves more voltage then the rev1 and 1.1's also. The dimm3 sounds fuct up, whats the highest you can get with a stick in dimm3?

Gonna have to get down and do a vdimm mod now

. Thanx for the heas up.

**Major** · 03-01-2003, 09:19 PM

Thanks twiggy, no big deal, not the first nor the last time I'll trash a mb. I just ordered another NF7-S v1.2 suppose to be instock on tue. Thought about an Epox this round but everone seems to be doing great with the Abit. I've been back on the A7N8X finally got it stable at 212mhz DC sync but just doesnt seem the same after running the abit !!!!:p I'm hopeing the new NF7-S will have an A3 on it I think it makes a difference.

**OPPAINTER** · 03-01-2003, 09:52 PM

Here is a single channel with mem at 3-2-2 Cas 2.

OPP

**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.

OPP

**RoydRage** · 03-01-2003, 10:17 PM

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

OPP

**Svenn** · 03-01-2003, 10:51 PM

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

**Svenn** · 03-01-2003, 11:42 PM

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.

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

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

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

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

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

**Major** · 03-03-2003, 10:08 AM

The early Asus bios where that way too, after 200mhz the increments took some leaps, but with bios 1002 they now have 1mhz increments up to 250mhz. It might be a limitation of the board but I hope it will be a bios thing.

(Im an optimist)

**dykz34** · 03-03-2003, 04:38 PM

Hopefully Abit will have 1mhz FSB increases in the next BIOS update... 5mhz is a HUGE jump when you are already so high...

**Major** · 03-03-2003, 06:17 PM

Well my NF7-S was only up for a couple of days b4 I killed it but definetly was MY fault, during that short period of use I'd say its a great board ! ordered another (didn't RMA) no problems with it at all.

WRONG

Check out the new BETA BIOS 16 which provides 1 mhz increments to 233, then and then 236/37/40/42/44/45/50.

Go Abit!

OPP,

Got my Rev 1.2... But this is my first NF-7... So I was hoping you could bring me up to speed...

What is the value you would use for a single resistor vDDR mod?

Do you know Of a thread that details the vdd mod... I can't find one... And what value would give me about 1.9v?

My NB Stepping is G31861.1A

025A3... I hope this is the latest...

About the FSB jumps, the 8rda+ is the only board that has TRUE 1mhz increments to 250mhz even the Asus is like 202/04-10/12-33/36/38/41/45/48/50 or something close to that

Twig,

I know 100Ohm would be a safe bet, but it probably would yield little, or no increase. It's got to be somewhere near the middle of the range..... But exactly where?

Thanks,

**twiggy** · 03-05-2003, 08:53 PM

A friend of mine is running a 10ohm and 100ohm resistor and hes on a rev1.0 and it gives him over 3.1v.

I have a 1k pot set to ~120ohms and it gives me 3.05v at 2.9v in BIOS.

**RoydRage** · 03-06-2003, 06:48 AM

Twiggy,

Ok, Thanks. That gives me an idea about what to go with. To start I'm going to go with a 60 Ohm...

Regards,

Royd

**RoydRage** · 03-06-2003, 08:09 AM

Bingo...

A 56 Ohm Resistor got me exactly 3.20 Vmem!

Now If anyone has any ideas as to why my vCore voltage it stuck on 1.6v Please let me know!

I've disconnected all the mods.... And it's still won't budge...

this is my 7th nforce2 board.....

JUST KILL ME, PLEASE!
