***Official nFORCE2 Bandwidth Thread!***

yes thats all very nice, but how many people here are running that kinda vdd for normal use? and how many people here are actually stable at any of these speeds?

what i wanna know is whats the highest vdd and highest STABLE mem clocks that people are getting in normal 24/7 use.

im at 1.91vdd and 2.9mem (shows as 3.0 though in bios), managed 225fsb at 7/2/2/2 on my NF7-S 2.0 with 2x256mb xms3500. system temp according to bios never goes above 31c under load which i think is fine using stock cooling.

This vdd I am using all the time. My max stable fsb was 230MHz dual channel before taking this 1.1 out of my sys to put in my new 2.0

After that I could not even boot at 220MHz fsb with my kingstons. So back to my good old 1.1 but my proc was changed though.
But now though pelting my nb as before I could not run fsbs like before

So I gotta test out the max of my 1700+ (near 2450 b/c of fluctuation of voltages) @1,78-1,82. Think I am gonna put some hs on all the mosfets to stabilize it more effectively.

Think today I am able to use 11*221MHz @2,0-3-2-2 24/7 and 4eva

Hoping on a fix for rev2.0...

I'm not sure if my mobo finally bit the dust, but if it did I'll be RMAing for a a7n8x 2.0. I was told that putting a 100mhz fsb processor in my board might fix it, so I'm going to give that a shot and hope for the best. Just thought I'd update people who were wondering why I haven't been benching anything in a while :P

Just to show I'm still @ it though, here's a Soltek 75FRN-RL maxed in the bios @ 211mhz with ease. I may be getting a 75FRN2, which allows for up to 250mhz.

Hello B4E, when did you buy the A-Data, and where if you don't mind sharing? Little higher and you'll have the highest bandwidth on th planet! Woow. Forgot who it was here who said the highest was 4K?

I bought A-Data a few weeks ago in Italy as well.
What do you mean when you say: "Forgot who it was here who said the highest was 4K?"?

Meaning your at 3700MB/s bandwidth, and 4000 = 4K, so if you were to breach 4000MB/s you would effectively have attained the highest memory bandwidth on a AMD system on Earth. If I read that prior statement correctly. It's here in this thread somewhere.

Yeah, I know it, but you must consider that my abit isn't modded and I only use standard air cooling system, so IMHO this is a very good result.

[shidokanjohn]

first posting here so i would like to say a big hello to all
this is mine bandwith with 2*256 kingston(winbond chips) running 223fsb 2.9vdimm for every day use

[Liquid3D]

Welcome, nice overclock there. Especially for DDR333. Is there anyway it'll run at lower VDIMM?

[shidokanjohn]

Thanks Liquid3D
At 2.8 vdimm can run 2.2.2.6 at 210 fsb
At 2.9 (3.06 with abits overvoltage) i have 223 at 2.3.2.6..
I think i can go 4-5 mhz more but 1.7 vdd holding me back
I have seen running winbond chips even 3.3vdimm for a long time working just fine

B4E your the man!!! Nice, really nice. Your going to have to find a Beta BIOS which allows for 275MHz FSB!

Hey shidokanjohn I just ordered the Soltek SL-75FRN2-L which allows VDD adjustment to 1.8V. It wasn't too warmly embraced initially because the board's 1st BIOS was only 200MHz FSB. It was then increased to 211MHz FSB, however; recent BIOS versions offer 250MHz FSB. And supposedly each board has the C1 stepping nForce2 NB. Speaking of NB's, I took the NB heatsink off my 8RDA yesterday, and the stepping was A3 so I was happy. I put an old Thermaltake CPU HSF on there, but haven't fired it up yet, because I had problems with my Prometeia's microfreezer contact. I think CPU temps were as high as 50C, but with the inaccuracy of PCHealth (thermistor is under CPU which is affected by Prometeia's low temps) I'm afraid I damaged my 2400+.as actual temps may have been over 60C. I had experienced all sorts of visual anomalies in the BIOS. Anyway, I'm going to give it a go tomorrow morning when I'm not so tired.

Really nice overclock guy's. Your inspiriation it can be done! But where the heck to you go after 250FSB? Wow.

nf7\s 2.0 full air,no mod....DC

[shidokanjohn]

Thanks man
I wish you good luck with your cpu
I will do vdd mod this week so i'm hoping too catch 230-235fsb

btw ztop very nice overclocking
:thumbsup:

I am stuck with this crappy efficiency 92% or so.. ingle channel though, also only 1.592v VDD and 2.8v Vdimm

Beleive me that bandwidth is nothing to feel too bad about, that's excellent. Man you guys are rocking! I have 2GB's of OCZ EL-PC3700 between my two rigs, but; I'm having trouble with my Prometeia, or I might be posting myself. In the interim, I can only watch you guy's have all the fun (little Cindy Boo-Hoo).

[Spec3]

vdd was 2.1V and vdimm was 3.15V

This was done single channel but I am now working on dual

Can someone point me to instructions for this L12 mod? What benefits does it offer for my 1700+ ? thx very much!

Look at the picture!

EDIT: This is a L12 mod for increase FSB default from 133MHz to 166MHz.

B4E.. what should we be looking at? What does that do?

EDIT: Nevermind.... *Smacks himself in the head*
