Gskill DDR610 on DFI LP UT

[kakaroto]

Got my 1GB PC4400 512MB 2.5-3-3-7 / 2-2-2-5 kit and tested it on the DFI.

lets see what it does on a Single channel platform.



================================================== ========
This mem does NOT WORK with the DFI with 2 dimms inserted, I get 10K errors in memtest #5.


I tested with a other 3400+ CPU and now with Drv Strenght bootable at 1, i come alot further with this mem. 275Mhz 2.5-3-3-5 @2.6v.
I have a strong feeling that is has to do with the Drv Strenght.



I ask jack from Gskill, he said it is a known compatible problem with single channel controllers :(

So only 1 dimm inserted you will get the max. mem stability.

Max stable is 265MHz 2.5-3-3-5 1T with 2 dimms inserted.
================================================== ========


with 1 dimm
2.7v
10/5 bios
Skew value = 128
Drv strenght = 1
4b burst enabled
All with 1T CPC.

woooow great timings at ddr 310 !!! :toast:

TCCD rulls ...

[st0nedpenguin]

Looks pooh, only one thing for it, send it to me! :P

Seriously though, nice timings for DDR600. :slobber:

[Holst]

Is that 1T or 2T, I suspect 2T judging by superPI.

I wonder what my Bh5 would run with only one stick.

Nice bandwith though :D. very nice.

The pifast is low cause of the CPU speed.

[=[PULSAR]=]

Wow really nice kakaroto, I think those are the best bandwidths I have seen so far here, excluding dual channel chips. Also changing the timings to 2.5-3-3-7 on the 2x512MB didnt help? Thats kind of wierd I thought DFI boards worked nice with this stuff.

[kakaroto]

Here a message from onepagebook feedback:

(2x 512 problem)

That 's nothing to do with RAM, that's really a big bug there even the designer of the board, Oskar Wu understand this prob. I heard several users have this prob though. Personally I will let Oskar know about this matter.

Thank you very much to let me know about this.

Looks like its a very serious bug .. :(

[SHiRaKaWa]

Is it 2x512 or 2x256? I'm confused
The label on the modules says it is 2x512 and sandra says it is 2x256.

Its one 512MB module.

Bank 0 is one side of the dimm with 8 IC's and Bank 1 the other side.

[SHiRaKaWa]

aha
thanx

[Zeus]

Nice speeds K! :toast:
Which dimm slot? 1?

Slot 3 seems to be my most stable slot.

[eva2000]

tried read preamble of 5.5ns instead of 5.0ns ?
tried no skew value at all ?

can the ram handle

Trrd = 2
Twr = 2
Twtr = 2
Trtw = 2

at any speeds ? what's the highest clock you can manage with them all at 2 for those 4 values ?

[=[PULSAR]=]

I think it might be something with the GSkill here is a thread with OCZ Rev.2

These are the max stable in memtest test#5 in DDR600 2.7V

One module can do 15 passes stable at settings below. Other module same settings only Max asyn 8NS and preamble lat. 6NS

TrFc =12 gives me "detecting array"

http://www.xs4all.nl/~famchow/Memory/Gskill%20PC4400/DDR600_settings%20002.jpg

Drive strenght level 1 works the best for me, higher only makes it instable.
Increasing Skew will stablize the ram, own experience.

DFI 939 + 3200+ Winchester + Gskill mems :P

That is some sweet ram.

[saaya]

wow, nice!

[jinu117]

Interesting... the 3700EB runnin @ 250mhz 3-3-2-8 gets 2027mb/s (ocz memtest). Wondering because of 350mhz diff on CPU speed or something? Wonder how these TCCD performs under similar condition...

Kakaroto, I'm curious, what is your HTT set at?? 3x?

[kakaroto]

Kakaroto, I'm curious, what is your HTT set at?? 3x?

Yes, if I set AUTO the bios will automatic set to 3.

[WeStSiDePLaYa]

damn! thats some serouis bandwidth for sure!

[rick_fx]

ddr610, nice! :thumbsup:

[Zeus]

ddr610, nice! :thumbsup:

Make that 620, but nice nontheless! ;)

[PytonOrm]

My Pc4200 Ocz does 320 x 2 in single channel :) timings 5-4-4-2.5 vmem 3.2v with abit max3 :mad: in dual still yet 288fsb :( tested into dry ice

[The Virus]

Yes, if I set AUTO the bios will automatic set to 3.

Your lucky man, I can't even do 217fsb on my FX55 and MSI NEO2, it boots but crashes when i try to run 2001mark. Maybe sata 3/4 are dont have pci lockage.

Kakaroto, what should the HT be set at for 12x217fsb?? This should give me exactly 2.6ghz which is stock speed for fx55. I got corsair pc3500c2 bh5 2x512 .

[Apocalipsis]

TrFc =12 gives me "detecting array"


What's that? I get that message past 320HTT speed, what means that? a wrong timing?

217MHz is very low. The Chipset is made for 1000MHz HTT.
So 217x4 is not OC'ing...
I think your HD is the problem, try the SATA ports from the NVIDIA Chipset and not the external SATA controllers (marvell, silicon)
My Marvell SATA controller on the DFI is also badly locked..

For safe overclocking set the HTT Multiplier to 3x, because the difference between 4x and 3x is very little to none. Most chipsets won't run past 1GHz HTT. (Detecting array message...)

That is a bios corruption..or some kind.
Reasons:

1. Overclock to high
2. HTT to high

I'm not sure what you mean. You want me to try SATA ports from NVIDIA? So are you saying that port 3/4 is not Nvidia??? The reason why im using 3/4 is because people claim that they are locked and 1/2 are not.

Well try them out :)
I don't have this board but i think that the 2 SATA ports close to the chipset is not NVIDIA. I might be wrong so test it.

[kakaroto]

Tested some more with the mem, and i founded the fastest setting for my Gskill Ram at DDR600 1T

Tcl = 2.5
Trcd = 03
Tras = 05
Trp = 03
Trc = 07
Trfc = 14 (lowering cause freezing)
Trrd = 02
Twr = 02
Twtr = 01 (1 or 2 are the same performance)
Trwt = 02
Tref = 3072 (200MHz, 3.9µs) (this is the fastest setting in pifast. select 4708 for more stability)
Twcl = 01 (keep this 01, higher will not boot )

Skew value = 128 (increase)
Drive strength = Level 1
Max async = 7ns lowering cause freezing
Preamble = 5ns
R/W bypass = 16x
Bypass max = 7x
32B Granularity = Disabled (8 burst)

Good work there Kakaroto.

[kakaroto]

Only 2 dimms is crappy on this board.

Hope GSKILL find a solution for this, cause i bought 2dimm and if i cannot run them on a single channel board. That is not nice :(

I cant run SPD speeds, my max stable is 265MHz 2.5-3-3-5 1T.

[Ubermann]

Twcl = 01 (keep this 01, higher will not boot )

You can try "5" also.
Dont really know what it is good for.

[=[PULSAR]=]

kakaroto did you try a timing like 2.5-3-3-10, they like the high Tras timing Ive noticed.

[kakaroto]

=']kakaroto did you try a timing like 2.5-3-3-10, they like the high Tras timing Ive noticed.

Will test it asap. :)

[mad mikee]

(Hey gimme a break, my UT is in RMA and I have to play w/ SOMETHING :D)

x9, 2-3-3-7 seems to work best

x10, 2-3-3-(7 to 10) all work about the same.

Something else for you to test out?

[Onepagebook]

that's the highest FSB I can go!

[kakaroto]

Nice result Onepagebook :D

btw.. is there already a solution for the bug with DFI lanparty with 2x 512MB dimms?

Several user say its a bios bug and has to do with the HTT MP.

[kakaroto]

Update: used a new 3400+ 512KB processor and now with Drive strength level1 I can get 280MHz 1:1!!! with 2x512MB. :toast:

So the issue must be the internal memory controller, this one likes Gskill.

yep, got the same issues when using 2 memory sticks on the DFI Single channel board;
with only 1 stick it will go past 300FSB :banana4:


got older 3200+ CG stepping CPU, seems I need another CPU upgrade? :mad:

[reject]

that ram looks really god can you get in in australia? i think that there is something about this board... my cpu wont go past 2160mhz stable and wont boot windows past 2430ish
so i tried raising HT and found 282x8 was as unstable as 270x9...
wth is this board doing to our cpus and rams

you should help people that have got this prob. ;)
Very nice found! Very nice. :toast:

[Dagalidis]

I had same problems with DFI UT NF3 250GB @ 2x512 MB ADATA VITESTA DDR500 when used DIMM 1&3....
Was not able to pass 255 FSB without MEMTEST errors....
But when i used DIMM 1&2 was able to reach 290 FSB CMD1T depending on DDR timmings used ..

Just try and see if 1&2 DIMM make some difference.... :D

[kakaroto]

thank you Onepagebook, I even hit 300Mhz with 2 dimms.

http://www.xs4all.nl/~famchow/Memory/Gskill%20PC4400/300MHz_1024MB.JPG

not quite stable, get errors in memtest but enough for some benches :)

I must experiment more with the drive strength and some timings.

[Onepagebook]

not a problem, anytime;)

[jlccarv]

Nice clocks!

Your Tras looks way too low... with RAS to CAS and RAS Precharge at 4, set Tras at 10 (minimum). Run some tests, see how it goes. :up:
