***Official nFORCE2 Bandwidth Thread!***

Since alot of us have nforce2 boards, and OPP mentioned that a new bandwidth thread should be started up, I thought I'd go ahead and get one goin.

Keep in mind, this is strictly for nforce2 based motherboards and just the sisoft sandra memory benchmark. And let's keep it in sync and dual channel (if you can). Feel free to list your mods, your bios, etc, so that we can all learn from each other :)

______________

I'll start it off by posting what I think will most likely be max FSB attainable with my A7N8X.

A quick overview of mods, 1.9v on the chipset, 3.12v on the memory, 1002.001 beta bios, cpu_fsb jumper @ 100, new battery, 85w peltier + chilled water on the core (-5 to -8C temps). My PSU is also vmodded and gives me 5.15V under load approximately (not sure if that affects the high clock.) Memory is 2 sticks of XMS3500 (winbond -5ns) in DC 100% sync.

EDIT: Timings were 2.5-7-3-3 @ 240mhz. 2-6-2-2 @ 236mhz

Great!!!!
mine compliments!!!
The system running rock solid?
There's a tutorial for modding A7N8X?

nice bandwith sys, what are ya timings?

Here's mine @225, no vmods, DC100% sync'ed, 2x512mb Corsair XMS3500c2. vcore@1.85v, vmem@2.8v, 3dmark benchable but not that stable. 2700+ unlocked. Will push it further with my newly arrived Prometeia very soon :D

http://www.yenz.net/benches/fsb225.jpg

HÂ¥percUbe: I'll have a guide up soon on how exactly I did everything on my site, Maximum OC. And as for rock solid, I could bench sandra, I could do most things in windows, I didn't try PCMark2002 but I will give that a shot eventually. Speaking of PCMark I scored 6464 @ 232 2-6-2-2.... was just testing.

Drozdov: Silly me I forgot to put it in... 2.5-7-3-3. 236mhz I can do 2-6-2-2 though. ;) (I will edit my post w/ this info.)

Okkk. Thankz!!
i'd like to view PCmark & 3DMark screenshot ;)

I'll upload em tomorrow, heading to bed now :cool:

Can you post an unbuffered sandra bench at the low timings.

Here's my bandwith @ 10.5x230 ...

And here's my PCMark2002 score @ 225MHz, both sync and SC DDR :rolleyes: ...

wellÃ:banana: Ciao :)
yes it's rock solid and 3dmarkable 233 dual channel, till 228 is quite easy

i'd better go with NF7 1.2 or 8RDA+ then A7N8X ,altought Sys got an impressive fsb with that ;)

http://www2.arnes.si/~mlivak/Benchmarks/3645.jpg

Kingston Hyperx 3500 2*256 MB/s cas2.5 6,2,2 vdd 1,98V vdimm 2.86V, this all with normal watercooled NB in warm room, no xtreme mothods, I'll try those soon :D

Like Spaceboy wrote POS Vdimm. I'm thinking of modding but can't decide if it's worth it, oh yeah Epox 8RDA here with 3117 bios, btw Spaceboy that helped a lot. With my previous latest bios, I got BSOD loading windows even at 230 in normal room temperature conditions

That is really, REALLY nice morphling1. Congrats on a fine workup!

I think I'm gonna lower my resistance a smidget (slap on a smaller resistor rather) and try for some higher fsb... not sure if that'll do it but it's worth a shot.

2x Corsair PC3500 XMS running dual channel in timings 4, 2, 2, 2 Vdimm 2.77V

Vdd @ 1.60 not Vdd moded "yet"

Dual Kingston HyperX 3500s,, 256Mb sticks,, 3.1V,, 7-2-2 CL 2.5
Epox 8RDA,, Chipset voltage at 1.9V

OPP

heres mine.. Not great at all..

Corsair 3500 2-7-3-3 @2.7v on a NF7. VDD@1.8v.

Wow huge score there OPP, let me see if I can get anything more out of my mem. with chilled water on NB :)

we need Vdimm Morph :);)

LOL yes we desperatly do :D I just bough trimmers today so if I wont' be able to get higher with chilled water, I'll do the mod this weekend.

i don't like to do extreme Vmod on POS mobos
my KX7 was a rock so i did 3 mod and still works great but i'm afraid that this 8rda could die on me anytime :(

Hehe ,as they say: if you wanna make the omelet, you need to brake some eggs :D

Nice :toast: your the man :D
Great bandwidth goodness, makes me wanna void my warranty :D

Sorry, this may be a n00b question... sysfailur how did you get to 240Mhz FSB if A7N8X is supposed to support only 211Mhz FSB??? (I think so :rolleyes: )

Sorry if I'm wrong... thanx, bye!

You should flash bios sometimes, and you will see some changes, up to 250 I think :D

wow, such a big change just flashing BIOS??? great!!!

Well the option to get to 250 is there but it would be mighty tricky to hit it! And without a chipset voltage mod or memory voltage mod on the A7N8X don't expect to get much past 205-210. :(

Yeah, finaly made vddr/vbt mod on 8rda+ So I charged my Kingston with 3.23V and got this

Nice job!! *gets bumped to 3rd place* :( hehe

This is my old board ( still has a chance at life- but doesn't want to work right now, and may never again).
4-2-2-2 timings 238fsb ( sandra says 239) 1.77vdd ( wish I went a little higher with this board b4 it went belly up)2.9vdimm

I never cut the L12 bridge on this 2600+/333 chip, but I did remove the JCLK jumper.
EDIT: 8RDA+ Rev1.0

Great score there muzz, I'm just slightly behind you with this one 7,3,3 2.5

XLNT score there morphling....... :thumbsup: , the 1.1 I have now doesn't run as good as that board did at 1.8 vdd...... still looking into what I can do to make it better......... wonder if the L12 will do anything for me? I know bowman said it did for his, and he has the same chip I do ( 2600+/333).... considering it.

XLNT ? sorry I'm not realy good with those abbrevations :)
What should L12 do ?
Oh yeah I squeeze a little more out of my mem, just a little to past you :)
http://www2.arnes.si/~mlivak/Benchmarks/mem%20rec2.GIF
I forget cpuid, but it was the sam fsb as before, just timings 8,2,2, 2.5

Damn I lose :( hehe Methinks I need to crank up tha chipset voltage! Rawr! ;P

XLNT= Excellent.....
I am regretting not cooling my old boards NB with at least a wb, and even better a wb/pelt combo and raising the vdd to 1.85+....... that board was rockin' at the lowly 1.77 missed opportunity there... I don't trust this board as much as that 1.....and have 2 156w pelts, but the wb I have does not fit, and I would have to design a hold down out of some strap metal and bolts....been thinking about that also, as this one stops around 233/234. may lower the resistance a bit... heheheh

Nice bench:toast:

I finally worked up enough balls to do the VDD mod and looky at what I got running dual channel :banana:

Those balls got to heavy for you to drag around anymore huh MM....:bounce: :bounce: hehehehehe

Good job man....... looking good there.:thumbsup:

Ya muzz those balls were getting pretty heavy :D


Anyways nice score to you too, I will see if I can get higher later, I just need to put a fresh OS on there again as I just killed it pushing a little to high :smileysex

I would ghost an image right after you do an install if it were me..... that way you don't have to keep reloading the whole thing after/if it gets corrupt.. loading an image takes about 5 minutes.:D

ya I should make a ghost image...I have just been to lazy/ forgot to in the past :eek:

Thats unacceptable...........;) :D

So are most of these high mem benches comming from the epos's?

Yeps, because no matter how big the pos is, it's still the best mobo out :D

Guys help..I have an issue

I have the MSI K7N2-L nForce 2 motherboard, a wiretricked Athlon XP 2400+ and Kingston HyperX PC3500.

I'm at max FSB @ 200 my ram only does 3,3,7 and the CPU won't go beyond 2.2 Ghz. I'm using AS3 on the CPU and a HHC-001 HSF...Temps are NOT a problem. I'm running this as of now:

CPU @ 2.2 Ghz 1.675 V

FSB @ 200 (DDR400)

Mem @ 3,3,7 2.5V

Now I know one thing, the MSI doesn't allow VDIMM adjustments...so I'm stuck at 2.5V....At DDR400 FSB Dual channel is VERY UNSTABLE, while single channel works fine...Is that whats keeping me from the 2,2,6 settings EVERYONE seems to have?!?!?! Also..the damn MSI doesn't allow over 200Mhz on the FSB..so what do I do???

Do I have to buy an ABIT NF7 V1.2?? Or is there any hope for the MSI??? Any suggestions are welcome as I want to move to the next level! :D

Hollywood... I would have to say that you'll need more VDD (chipset) voltage to stay stable in dual channel. You might also want to try TIGHTER timings believe it or not that might work. Also check for bios updates constantly!

Thats the problem SYS...it seems that the damn K7N2-L has NO fix for the VDIMM settings. Anyone here heard of a fix for us poor, wretched MSI users?!?

I just realized that you meant Chipset voltage (VDD) Duh...Man...That means I may have to slap on a better HSF for the northbrige and do a VDD mod on my mobo...hmm...wonder if there's any mods for the K7N2-L out yet. Now as far as the ram voltage..I think MSI will resolve the issue via a new BIOS..but it's already up to version 3.3 (started at 3.1) and they still have yet to fix the VDIMM issue..

You guys are absolutely sick!!! These have to be the highest scores on the Planet!!! This forum houses the best overclockers on the Internet without question. Congrats'! I better get my nForce2 board ASAP! "This is madness!" (think of Phebe's voice, and intonation)

this is mine :)

http://digilander.libero.it/mybenchmark/sandra230.jpg

This is with vdd at 2.00v and vdimm at 2.85v (real)
Timings are cas2 4-2-2

I'm using 3129 bios because of cold boot bug resolved, do you think I can squeeze out some more bandwith using earlier beta bios?

sweet :)
gotta get me some pelt action :)

Heres my bench using some nice cheap PC3200 Twinmos :) $57/stick.

CCtaylor, this thread is for nforce2 boards _ONLY_. Nothing else.

My 8RDA+ @ 231MHz 1,85V running Xerox PC2700 (Samsung chips) @ sync 2,9V.

Now I'll have an awesome database to work with when I get an nForce2. Probably going w A-bit's NF7S-ver. 1.2. It look s like it will be the best one out. For now.:D

it is? what makes the bit board better? more options higher options? new chipset revision?:confused:

a little update

8RDA+ dual channel


http://digilander.libero.it/spaceboyz/238-dual.jpg

I'm guessing it has either a PCI lock in the BIOS or they put the one sixth divider in there or both. A friend got his UPS tracking number on his w/a new T-Bred B 2100. So he should be getting his on Thurs. So we'll see what the things got. Excaliber PC has a combo deal w/the CPU & the new NF7-S 1.2 for a low low price. You'd think I work for them. Anyways, you would've had to order over the weekend to get one this week. They get a new shipment in every week. But they sell out almost immediatly. :)

NF7 at 250 :D

OPP

the NB is only watercooled or do you put the TEC on?
1.96v?

:toast: Opp
And I also wonder what kind of cooling you use to achieve that, plus voltages & timings

That's awesome OPP. With the rev 1.2 I assume? Also: How? ;)

Its only one stick at 7-2-2-2.5,, I am still only water cooling the NB. I was useing 2.1V VDD, 3.1V on the mem.
I was at 10x 250.

OPP

wow, such great score with single channel, Sandra must realy like FSB :) Is that with Kingstons ? What about DC how high can you get ?

WTG OPP :thumbsup:

Not many hit 250.

I'm not sure how many have seen this as this thread is kinda hard to find, but on this thread, 3 Finnish guys got sick overclocks on the A7N8X Dlx.... 250mhz DUAL channel 2-4-2-2, 250mhz dual channel 2-5-2-2, and 242mhz dual channel!

250mhz 2-5-2-2 gave 3901/3669!!! ===> http://users.kymp.net/p203463a/A7N8X...50cas2225d.gif

now i know cause i got lower score at 238 Dual than other users

on 8RDA 7-2-2 is better than 5-2-2 :rolleyes:

FOOOOK, what the hell are they using LN2 on NB and memory itself or what :D:D

Thats incredible for an A7N8X

Yeah Sys I saw that.... the guy disturbed posted that here.
Great clock for certain:thumbsup:

My FSB with 8RDA bios 8RD13305 (NO Vdd MOD!!!)

http://digilander.libero.it/LunaRott...LES/My_FSB.JPG

Sandra is not important cause I can't use synch RAM/FSB...my XMS 333 doesn't work correctly over 205MHz...

...but FSB without Vdd MOD is very impressive!!!:banana:

CYA

u can go till 240 without mod in Async mode ...

Sorry, but I don't understand!!!

Could I go till 240MHz in asynch...but not in synch???

Help me for understanding!!!

CYA

P.S: Sorry 4 my english

219 no vdd mod?!north cooling?dual or single channel?can you run sandra or sup-pi at 219?

Single channel...only a 5x5 fan over the SPP's original dissy

Yes I can close Super PI & Sandra memory test, but my memory is asynch with FSB because XMS 333 doesn't work at 219MHz...so I setted them to 83% !!!

This is my screenshot with this configuration

You will get higher performance running fsb/mem synched than asynch.... at 200mhz synch those scores in Sandra will be in the 2900 -3000(INT- Buffered) range.... try it. Do some benching of different apps like sandra/pcmark/3dmark/games synch( around 200mhz, or the best you can do synch), and I think you will see what I am trying to say B4E.

Sure, I know what you mean, but I wanted to see where I could arrive with my FSB.

My RAM works max at 414MHz...so I coudn't test it with higher FSB!

Actually I think that's dual channel, but lower timings. I scored 10 lower on the Int, but scored 19 higher on the Float w/ my dual chan @ 2.5-7-4-4... so maybe he was using worse timings? Not sure.

Yes it's SC. 3th ram slot won't work above 220Mhz reliably when benching 3D, allthought pifast and sandra mem test work just fine 242MHz DC. (4-2-2-2 3.2V Kingston HyperX PC3000)

Of course, leave it to OPP to leave no room for competition... like my generic PC2700 could stand a chance anyway.
