hmmm

Remember, that Largon number was with UTT-CH...as he edited his post to note.

We struggled with BH5 for a long time without great results....TicTac tried a bazillioon bios hacks. But I've always felt "something" was setup as a default in the bios, with no user abilitry to change it, which was holding back BH5 results.

As we see with the UTT-CH, the AthlonXP's and the NF2 memory controller CAN do high speed 1T, but refuse to with UT-BH5/old-BH5. That smells out loud of a memory setting default being "incorrect" for the ram.

But all the manufacturers stopped BIOS development and moved to A64 and we never got it sorted out. At least DFI with the LPB/Infinity got closer to sorted out than others.

Myself, I'd suggest either get UTT-CH for 250x10 or the Mushkin 1G sticks for 230x11 operation with a 2500/2600+ mobile XP and be happy.

Otherwise I'd switch to A64 and use the UTT-BH5 in a NF4 based system.

i see... thanks for your correction and explaination. sound like I got nothing to do with the utt bh5, either I sell it or move to NF4 platform.

off topic,

uwackme, the below vtt mod is limited by 3.3v rail (mean max 1.65v) or it always half of the vdimm?

Atleast SPi 32M stable. Don't remember if it was actually stable

Edit: Ok, ok! It's CH-UTT...

Yep....Gotta luv VX

These are for my NF4 board but im waiting on GPU RMA so
toss em in my LPB and viola...

my vx 4000 wouldnt boot on my dfi nf2.....

I am running the same bios on LanpartyB
with VX4000

seldomsean,

your vx4000 on LanpartyB is based on 1T or 2T ?

hmmm

I think that Vmod yeilds Vtt 1/2 Vdimm....and you use the 3.3V rail voltage control of your PSU to raise the 3.3V rail to get higher Vdimm/Vtt then the stock 3.2/1.6 max.

On the Infinity, the Vdimm comes from the 5V rail, so a simple one pot Vdimm mod allows up to 4.0V Vdimm. I was using 3.45 with my UTT-CH.... bios set for 3.3V = 3.45V in reality.

It is CPC On in the bios... 1T..

EDIT: I am running this Bios from "Hellfire" (N24ID619-8KA-REV2)

and it seems to run very well with my board so-far...
Tic-Tac's 2-15 5035T for LP-B had given me the best results
before i found this one.

Well now, I actually had ran SPI32M with those TMSPs on even higher freq:
http://www.xtremesystems.org/forums/...id=36449&stc=1

I had 6 sticks of this stuff, tested them and sold 4 weaker sticks. All did atleast 245MHz 2-2-2-11 @ 3.3V on nF2. :p:

If you ask your memcontroller, those 256MB sticks of BH-5 are single sided - even if the IC's are on 2 sides.
Check the link under the big pic in my sig.

well, i'm using ddr booster now, so my vdimm is not limited to 3.3v from psu rail. what I ask is about this vtt mod, since the mod does not required pot, isn't when i adjust the vdimm up to 3.5v, the vtt will be half of it, 1.75v automaticly?

Hi all,

I think I can add something to this thread so here we go:

Let me first say I was using 2x256MB Corsair BH-5 at 256MHz FSB rock solid, so I know the limits of my motherboard :) Here's my experience with 1GB Kit(2x512) of UTT and BH-5 with the NF2-Ultra chipset:

note: All test were made with tictac's Mantarays XT CPC OFF. With CPC ON It was a real "no go" with 2x512 sticks.

With 1GB GEIL PC3200 Ultra-X kit (UTT IC's) I can run memtest at 10.5x248 2-2-2-5 (3.3V) with 4 sometimes 8 errors per loop. I'm currenlty burning in those sticks so no reliable test were made with the OS loaded. I can only say the max I was able to get into Windows was 10.5x256 with 2.5-2-2-5 timings.

With 1GB Kingston HyperX PC3000 kit (BH-5) memtest showed lot's of errors even at 230 FSB (2-2-2-6 / 3.45V). And the Max I could get into Windows was 240MHz.

So the only thing I can conclude here is that the "new" UTT is by far superior then the old school BH-5 when mixed with NF2-Ultra chipset. Not to mention the UTT is more flexible when it comes to memory timings whether the BH-5 have take no benefit when you relax them.

tip: I'm using uwackme's BH-5 burn-in guide and I'm getting great results with it, give it a go :toast:

Regards,

KODE.

hmmm

On the NF7-S... not sure. Vtt has its own regulator that needed a seperate pot to control correctly. I never used the booster, I cant tell you.

Simply moding the Vdimm did NOT have Vtt follow it on the NF7-S. It did follow on the Infinity, LPuB, and Asus A7N8X boards.

I didn't realize until now that the DFI nf2 has all of the extra ram timing capabilities like the nf3 and nf4 DFI boards. I didn't know that any nf2 board did that. I just saw your sig, uwackme. My nf7 was like 4 timings and thats it, lol.

KODE,

your replied will be appreciate. :)

hmmm

GM, you can use the WPCRSET program to force in windows some of the additional timings on any NF2, but you end up needing to boot at lower FSB, set the timings, then use clockgen to up the FSB to where you want it.... the penelty for the settings not being in the bios.

To me if sticking with NF2, it's worth it to hunt down an Infinity. As much as I luv'd the NF7-S, ABit really let us all down when they ceased supporting changes to the bios. Some stuff is too complex for TicTac, etc to deal with on patches.

LOL I´ll prolly fry this one but I´m a die hard mofo when it comes to achieve goals...

250MHz /2-2-2-5 with:

2.3Vdd :stick: :slobber:
3.5Vdimm
3.9V on the 3.3rail

So far so good, 25 passes on memtest and climbing :toast:

your utt running 250 @ 2-2-2-5 is 1T or 2T ?

what's the point? seem only dfi nf2 can run utt bh5 well with 1T. maybe dfi bios provided alpha setting?

hmmm

Yes the DFI has all the memory timings settable in the bios.

but you're barely get 225 @ 2T on DFI infinity. why? :confused:

Altough I managed 250MHz FSB to be memtest stable, it is not 3D stable :( still working on it.

Looks like the ultra high Vdd is the culprit here, not sure yet.
