Sinking pll and mosfets? 230 not acceptable : /

[PanaBob]

Rig: NF7-S v2 w/ vdimm & vdd mod, 2x256MB KHX BH-5, 2500+ M (does 2.7), 480W Thermaltake B'Fly 3.45v, 5.3v, 12.4v, MCW5000 on CPU, MCW20 on NB. 11x230 for everyday use, 11.5x230 for benching

Here is a short summary of how I got to where I am now:

Before I was stuck at 225FSB with 2.9vdimm (its actually 2.97v if you read the vdimm with a meter) in DC CPU Enabled of course. I was using OCZ PC3700. After doing the L12 mod I could boot up to 240-245 depending on the BIOS! But then I you guys convinced me on BH-5 for the NF2 and NF3 so I took a chance, got 2 sticks of KHX at zipzoomfly, did the vmem mod and now my memory passes memtest86 upto 243Mhz with only 3.08v. I also did the vdd mod, I get 2v when I set it to 1.7v I watercool my NB so no worries about heat. After all this, the blend torture test only passes upto 230FSB 2-2-2-6 DC etc. : /
I would think I would get better results after all that?
Or does the blend test usually not pass after a certain point on NF2 boards?
Maybe my memory needs more volts?
What about putting a big ramsink on the pll where you read vdimm?

Any tips from the xtreme members would help ;)

L12 mod on a Barton? OK what did you make it? 200 FSB default? or 133?


I would try more juice on the mem side. Its BH-5 so it will easily handle it. 3.2 - 3.3 should do the trick. Also some boards work better with slots 1 & 3 , and some like 2 & 3. You probably already tried that, but if not, could be another thing to try.

Also, SB cooling - try throwing on a heatsink & small fan onto it, its been known to improve things as well, I know it did for me.

Might want to give BIOS 14b a try - stock or one of tictacs modded ones, they've been known for strong 11 multi performance.

Good luck.

Well I'm running a Mobile Barton. It defaults 133FSb so I made it 166Mhz with L12. When my room is nice and cool I can run it at 2.65Ghz rockstable.
eh, I actually forgot to try diff dimms. I'll try d14b too, good suggestions. I have two large ramsinks with ASIII and a lil epoxy on my SB. That 120mm fan gets air moving over most of the mainboard.

Nice looking rig you got there man :toast:
I like the 120mm fan mount.

Of course there is anoher way of getting high FSB - pick up a DFI mobo. ;) Thats what I am doing :D
I found the Abit fun to play with, but getting much above 230-235 (100% stable) out of one takes a lot of luck.

DFI performance seems more consistently in the 250+ range.

[PanaBob]

Yeah I think I'm going to get one and then I can really see if the Abit has better clocks then the DFI or not :thumbsup:

I have had 2 NF7-S v2.0 (D18 and D19)
Vdd mod usally gives 5-10MHz not more.
L12 mod made me lose 2-3MHz on my XP-M, but thats different from what board you got.

Actually the board that did worse stock is that one that did best modified (Newer D19 one)
231.8MHz FSB 2.06-2.07V Vdd Air cooled is max however, but the one before that couldn't run 230 with more then that so i'm pleased...

G|-|oST
Yeah, most DFI seems to hit around that, but i havn't seen many that are actually 100% stable there.

But i do not think it's worth getting the DFI now or if someone already got another nF2 board at 225MHz+..
I don't see the point on "benching" this 1.5 year old nF2 chipset anymore...

Nice system PanaBob :D

[S!1v3rB@cK_Dk]

Man that is a nice case.. Very stylish:slobber:

[PanaBob]

Appreciate the comments guys :toast:

Well the D14 is where I am going to stay. My temps are down, and now FSB is good from 230 to 235 with the blend test, so 11.5x235 2-2-2-11 for 2.7Ghz will be for benching :banana:

Since I might make my sister a PC, I'll think about getting my hands on a DFI and some more BH-5 just for fun now that I just got hired out of college
:banana3:

.. the highlighted molex is where I check my vdimm

[G|-|oST]

Yep the good old D14 :D

As far as the temps being 'down' - they are just shown differently with older BIOS revisions. They are not 'actually' lower.

Awesome results though, now lets see some benchies at 2.7 :toast:

[PanaBob]

How fast can Barton's do SuperPi at 1M?

[SAE]

About 34seconds ;)

[PanaBob]

My Mobile Barton doesn't like anything over 2v :confused:
I'm happy with it though, it will holdmeover till Socket939 later this year

SAE, thats pretty wicked :toast:

If I keep reading this thread I'm gonna fry my hardware from drooling on it :slobber:

LOL anyway prime95 is very strict, you can run games at like 200MHz higher clocks than prime95. Pay no attention to prime95, try 3dmark at 240fsb
