Duonger,

Would you recommend I get the Redline XP4000 (2 x 512MB) for use on a DFI nF4 mobo? Some are saying to stay away from anything UTT at the moment. What's your position on this? I tried searching through the Mushkin Forums...hacked.

Thanks,

Scoot

Why not!!! they have a warrenty, so if they go pop RMA them
:stick:

That's the thing though, don't want them to go 'pop' lol.

actually we have been trying to investigate this more and more. we have talked to several people and are waiting for dfi to get back to us too. i will post an update shortly about this here and on our website.

from what i can tell as of right now,. it is a board issue but we dont want to point fingers till we have identified everything.

Duonger

Thanks for the info and quick reply, but if the Egg happens to get these babies in stock today or tomorrow, I'm going to end up purchasing them. The RAM is worth it, I'm optimistic in both Mushkin and DFI on coming up with a fix for this issue.

Memory Death:

We use two stages of linear regulators to generate the VDIMM on the DFI NF4 motherboard.

1st regulator from the psu’s 3.3v or 5v line to VDIMM sets the target voltage to 4.1v, or 3.2v (depending on what how the J17 jumper is configured). The 2nd regulator controls VDIMM voltage to the memory modules themselves.

Explanation as follows:

In 3.3v source jumper mode, the 1st regulator will output 3.3v to the 2nd regulator. The 2nd regulator handles the voltage output to the memory modules. (2.5v-3.2v)

In 5v source jumper mode, the 1st regulator will output 4.1v to the 2nd regulator. Then the 2nd regulator will handle the output to the memory modules. (2.5v-4.0v).

ATTENTION:
The DRAM voltage as originally supported by the spec is up to 2.85v only. Jumper J17 allows you to select beyond the defined spec. Although the function is supported (at the hardware level), selecting a higher voltage may cause unstable current supplied to the system board which may subsequently cause damage to the CPU and DIMMs

(copied from the warning sheet supplied with the DFI NF4 motherboard concerning the J17 5v jumper and also found on page 9 of later revision NF4 motherboards (A02 and later))

Using this design, the 5v source voltage will not exceed the VDIMM source from the 1st regulator (4.1v). This circuit will not supply DRAM voltage higher than 4.0V(4.1V-0.1~0.15V) no matter what kind of user error or bios error.

Using this type of linear voltage regulation is very resistant to any voltage spiking and in the DFI labs and in independent testing no spiking at the memory sockets has been observed.



To conclude, there has been no evidence that the DFI NF4 motherboard has been responsible for any memory death. You can choose to not believe this if that is what you want to do. We have done extensive testing and found no evidence that the board kills memory modules though, and that is the truth, no matter how much some of you might want to flame and shout that you 'know for sure' that the board does kill memory.


===============================================


Cold Boot:


We are working on a new bios to correct this for the relatively few users experiencing this situation.

Oskar expects a bios to be given to me by Monday that I will be able to give out to select users with this problem to test. We cannot guarantee that it will solve the problem for any or all users. We can only have the bios tested by users with this problem and try to refine it to hopefully alleviate the situation.



that is all i am going to say on the Cold Boot issue until Oskar does give me the bios and I have been able to have it tested by those of you with the issue that are willing to test it.

so memory or board?

Still vote memory, Said it once say it again!!!!! voltage spike high enough to blow memory would blow On die controller first. This has already been proven in the past with early shuttle boards.
I also have a very strong feeling a good 20 percent maybe user error, flashing bios with high volts still enabled, over volting, poor cooling.

The thing is I cant see anyone owning upto a dodgy product :banana:

:am: it seems most of it is UTT and it is UnTesTed from winbond unlike the BH-5 and stuff that no one has problems with....

the UTT is not tested near the conditions of BH-5/6 ect.

memory is my vote too!

I thought DFI already fessed up to board issues, HOW could it be the sticks?? And they're covered by warranty anyway, so what gives??

Winbond-UTT is weak and might not be as good as an old BH-5, throughly tested by Winbond in high-heat/high voltage owens before it leaves the fab. Most memory module manufacturers test sticks manually using special testers but only fabs have owens that heat up ICs to 60-70C and apply high voltage to simulate months of "normal use".
Like Angry Games stated, 99% of truble cases come from users with UTT based sticks, which are NOT tested in a fab and as some may have a long, high voltage life, many others may not.

i dont want to RMA my stick every two weeks and plus Duonger said the UTT chips are getting real hard to get so who knows how much they will have if everyone RMAs their stuff!

- jiff - Actually that percentage might be higher... especially in lieu of the fact that Vmem is applied after AC off/on cycle before the MB is powered up...

- stealth - some of the memory vendors do a lot more testing than you give credit for... but there is a difference between the old BH5 and the newer CH5/UUT - thinner gate oxide, smaller feature size...

- Charlie - regarding the Black4400... before my CPU went belly-up on me, I was playing around with mine and had gotten this far ;)

FYI... regarding testing:

Mushkin testing OCZ testing

Peace :toast:

EMC2- ive read throught the threads you posted and thank you for making me aware of a bit more about the issue. bottom line is now one knows what the h3ll is going on right now. pattern does seem that UTT is most often being killed reguardless of testing precedures. who knows what ganna happen. time will tell

that's some AWESOME 4400... wish mine did that well!! How many V??

-- stealth -- I agree, the problem is far from sorted out yet... and likely is a combination of things (some cases not dead, but cold-boot issue - some cases killed by inadvertent user mistake - some cases as you say who knows atm). Time will tell ;)

-- Charlie --
My Mushkin Blacks definitely have a small sweet spot for voltage... found that 2.8V + .03V in BIOS (2.905 actual measured) was the spot for mine. 2.8V + 0 (2.857 measured) and 2.9 + 0 (2.958 measured) cost me ~15Mhz. BIOS and drive strengths are what I suggested in your original thread on them ;) Just hope my replacement CPU (whenever it gets here...grrrr) has as good of a mem controller! I would further note that very clean and stable PS rails are important, as you can see from the size of the sweet spot (probably on the order of 50mV). I was tempted to mod Vmem regulator for manual tweaking to see if I could get the last 5Mhz... but right now with the state of things regarding the MB, decided against... maybe later on.

Peace :toast:

Churned through the whole thread....

But does anyone know whether these Redline produce good results on an ABIT IC7-MAX3?

It's fully volt modded and top notch (under prommy), but I don't want to invest if the sticks aren't going to perform with the P4. Any advice/info appreciated, cheers :)

After much reading, it seems that unless I get a cheery picked set I'd be better off with some good TCCD/TCC5 like the OCZ PC4800 or G.Skill

Tho I'll have to get meself some of those red heatspreaders :D

beginning to have cold boot issues with my setup. Been running at 260x10 24/7 prime stable, but now when i try to restart i get the long beeps. :stick: Instead of powering right on, i have to power on once for the beeps, power off and wait for 5sec, then power on. Usually gets up on the 2nd time, but now every so often it needs a third time to boot. :( Looks like ill be leaving mine on 24/7/365 no matter what.

-Zach

Kind of ironic that my cold boot issues start this morning....last night i bought a Mac Mini to use so if this one dies i still have a PC :toast:

Next week, I will test some Mushkin Redline XP4000 on my SLI-DR but I would like to know what is the best way to start testing ?

The best bios version ?
The best slots to use ?
If possible, can anybody post bios settings for these mems ?

Now I'm using Gskill pc4800FF and that's a completely different thing !

Thanks for your help,

use the yellow slots and bios 510-2. Drive strength of 8, data drive of 1. There are plenty of different A64 tweaker shots floating around this thread. My suggestion is just print one out and set the corresponding values in the BIOS.

so yellow slots have been doing the best? muy interesante

Do these mems perform better after a burn-in or that's not necessary ?

basically anything silicone will do better after burn-in. even older silicone breast implants do.

use this method to burn-in...

works amazingly!
