well i know mem is stable unfortunately cpu isn't stable at 11x cpu multiplier





but

2nd fastest pifast and superpi 1M time with 11x 264mhz 2-2-2-6 with 2x 512MB OCZ PC3500 Platinum Limited Edition BH-5 on DFI NF4 SLI-D 310 bios




highest with 2x 256MB KHX3200K2/512 BH-5 on MSI K8N Neo2 1.36mod bios

[esdee]

Eva2000 how much did those settings helped?

Skew = Increase
Skew Value = 255

Nice RAM there ...

[eva2000]

They helped me pass test #8 in memtest but that was before i figured out increasing LDT voltage and chipset voltage did the same thing = help pass test #8

[saaya]

cant wait for my bh5 that does 250 with 3.1v

excellent job eva!! Nice complete testing too...no doubt in my mind those sticks are the real deal on the DFI.
I was playing around with my mushkin 512's yesterday and this is what I got with the 210 bios and 10x with a winnie that only goes to 2.7 on air.

With 9 multi, the same sticks went to 279 pifast 1m stable
This board loves 512 sticks of bh5.
I want to test that 310 bios now today with some of your settings to see if I can get these farther.
Thanx again for your work

no probs... nice clocks max for mushkin with 32M superpi ? vdimm used ?

looking good this DFI NF4 board it's first time i used doubled sided BH-5 on it heh i wonder how well my 2x512MB Mushkin PC3500 Black LVL2 BH-5 and Corsair XNS3500C2v1.1 BH-5 and Corsair XMS3200C2v1.1 BH-6 handle on this board.. guess I'll find out soon

That was with 3.6vdimm, 1.5vchipset, 1.2v ldt.
I have been inspired by your post to give these sticks and the dfi hell all day I never really bother with larger calculations in pi because im mostly a 3d guy and more times than not when a component is 1m pi or pifast stable for me, it will 3d at same speeds.
But....after seeing your post I want to try today for some larger calculations just to see where they end up. In fact, I think im going to throw just about everything I can at them today, I have nothing to do all day
Did you notice a big improvement with the 310 bios compared to the others?

I bet you will have great results on all your bh5 with the dfi.

[eva2000]

well first time used double sided BH-5 and it was with 310 bios never used prior bios for the ram so can't say.. only reason i updated to 310 is reported divider fixes and 218 bios i couldn't use DDR266 divider pc won't boot when i had 3200+ winnies heh

yeah throw everything you have at them - i think latest competition is to see who has fastest 32M superpi time

[Rondrian]

how do you cool these sticks at 3.6 v ?

[eva2000]

2x 60x25mm fans strapped together sitting over dimm slot retention levers - ghetto fatality cooler like

[EMC2]

Nice work, nice clocks, and nice info Eva

[KaEL]

darknico... woah 273mhz! i guess you confirmed my results hehe you removed heatspreaders ? as you list the PCB details ? i still have heatspreaders on

darknico care to share all bios settings/voltages and timings/a64tweaker as well

My PC3500 LE are BrainPower 808 too .

eva2000, you don't have to remove the heatspreader to see the PCB Version


Well, I suppose all are BP 808, due to that OCZ BH-5 LE perform better than others BH-5 sticks.

"...When we asked OCZ about these improvements, they indicated that they were using a new PCB, which was designed to achieve higher clock rates with Winbond BH5 chips."

They helped me pass test #8 in memtest but that was before i figured out increasing LDT voltage and chipset voltage did the same thing = help pass test #8

aka helped the IMC ...

noticed it too with my 2x512 UTT, impoved the stability at 270Mhz++ in windows, raising the Vldt (to 1.5V)

keep up

[eva2000]

hey ya right just checked side of the PCB and it says B6U808

[REDKEN]

I'm very happy that BH-5 is still alive. I'll be buying a DFI soon and was planning on getting some TCCD with it, BUT, after this thread I'll hold off and test my LvII Munchies first.
They haven't let me down yet and have been one of the better investments I have done to my PC.
I can get them to 250 @ 3.43 on an 875P sys. Can't wait to test them on an A64 sys. I'll put some benches up if they will help, but it'll be a little while though

I’ll be trying your bios settings EVA, thanks!

[Dynasty]

Same thing happen when i was using my BH 5/6 sticks on the POS K8N Neo2.
No matter which bios i tried my BH ram would max out around 230HT
Now on the DFI nF4 U-D and the sli-dr my BH ram is King again high 260HT
with 3.39V through them.

DFI nf4 with BH/VX ram is just superb

[eva2000]

No probs REDKEN, yeah Neo2 doesn't like double sided BH-5 much but runs single sided BH-5 fine

[wfarid]

funny how after how many years of bh-5 being out it still kicks ass, that's rare in the pc world (unless you are talking about crt's)...

great job! and i wonder how you'd do with pelted ram, dont bh-5 sticks get really hot @ really high volts?

Heat isn't really an issue for most RAM, someone tried phase-changing their RAM and didn't even gain 3Mhz, its useless, a nice size fan works just as well.

[Arnar]

Ive got a 2x 512mb Kingston HyperX PC3200 BH-5 and also the DFI nf4,

they do 260mhz 2-2-2-6 @ 3.5v

I have though not raised the LT voltage, maybe I'll try that

[eva2000]

nice Arnar using what advance mem timings for ram ? Good to hear as i got some 512MB KHX3200/512 BH-5 here too

[andL64]

got on 3,5V on the DFI 270 2-2-2- still testing

[Arnar]

eva2000, I had everything else just at auto.

I tried the excact same timings as you posted and I had to back down to 250mhz to get it memtest stable, I ran it all night at that settings, so its stable there

Didnt seem that more vdimm than 3.5v helped

I see yeah AUTO would be pretty loose timings for those advance bios mem timings
