TCCD DDR600+ DFI nF4 Ultra/SLI guide

[kiwi]

Noooo STD is a testing procedure in Memtest86++. You can select the test with "test selection"

Ik use 290MHz HTT with 1.2 LDT / 1.5v chipset.

Ah yeah! lol stupid me

Hi there,

First of all, thank you for this guide!

But I have a problem here, those settings seem to work fine @ 1:1, but with the 180 divider, I cannot have my mems stable at 282MHz.


My rig is:
A64 3000+ @ 3100MHz, S&M 1.51 stable (Prommy cooled)
DFI NF4 Ultra-D
OCZ Powerstream 520W
ATI X850XT PE
4x 160 @ RAID0
and of course, 2x 512 GsKill 4800LA




Any help will be much appreciated



Thankx

I still need help on this....

Come on guys, give me a hand here ok....

My 1GB GBLE 440 set can do 286MHz 2.5-3-3-7 @2.8V how much can I gain raising the volt to 2.9-3.0V?

[fareastgq]

Here's an update, after a clean install, I was able to run the ram dual channel with the relaxed timings and managed to get it 3dmark2001se stable, it's very important that you relax the tref and change the idle cycle time to 128 or 256, these are the only settings that I could get to run 3dmark stable, (bios 2-17), I was using this bios because this is still the ONLY bios for me that doesn't corrupt my OS install no matter how much I OC. For my system I still feel this is the best bios, Also, currently I am not able to max out the potential of my chip due to heat (dumb stock cooler), I have no doubt under water this chip will fly at 2.7 gigs and 275-280 HTT dual channel (I'm talking 100% stable for 24/7 oc now) , in memtest I was stable up to 280 HTT dual channel on 2.7 volts, seems to get into windows though, I need 2.9, the sticks are hotter running memtest than any games or 3dmark, thanks to OPB for the new sticks, they rock man. One last note, I ran 1T timings.

Ah yeah! lol stupid me

"STD" is just the whole testsuite test #1 to test #8, without the "extended" tests.

Still....i have some problems with memtest since it looks it literally has no use EXCEPT for checking that memory sticks are working ok, or that they get enough voltage etc. to work properly.
Ok, this alone is certainly already worth a lot !

BUT
If you see my other posts.....and the OP's comments....dont even ASSUME that a bunch of memtest runs gives you any indication about stability in Windows or in games/apps.

I had it happen that i run 15 tests #5 ok and STD and test #8....and with the very same configuration i couldnt even properly boot into windows...not to mention that it was only prime stable for 5 secs etc.

So...check your memory sticks with it...let it run a few runs to make sure your memory is working ok....but for overclocking and tweaking OCCT or prime is much better and memtest is almost useless !

There are now TCCD 507 to add to the list too.

will do thnx. Are there any test with the new 50x series?

[althes]

Great guide, I will definitely be using it today with my tccd 2*256 la

[rick_fx]

Great guide!!!

Got 300MHz 2.5-3-3-6 at 2,7V.

With a little tweaking, tccd is now stable at 2.5-4-3-5 @325 with 2,9V

[LowRun]

There are some done with 504 and very few as of now with the 507, you could eventualy PM Computermsa for further infos. I got my 4x512 507 stick courtesy of this young gentleman but i'm waiting for the Venice to compliment them with and have nothing serious to test them right now, will do ASAP.

My PDP 440 TCCDs can't do even 275mhz with the exact settings on the first post. I wondering why. voltage i gave was 3.0V.

Holy crap, actually rated for 350MHz @ 3-4-4-8, 2.95v
That's some crazy shiat, i sure can't see DDR2 (or 3 at this rate) taking over as the standard any time soon

try 2.75v

[arctic-k20]

great guide - really helped!!

guys - i was wondering if anybody had suggestions for me to try and tighten some timings in my setup:

300x9 1:1

2.5-4-3-6-9-14-3-2-2-2-3072-auto-incr-255-7-2-8-5-256-en-16-7-dis

those settings get me 32m superpi stable but if i put trcd to 3 it errors out pretty quick - they are ocz 4200plat tccd and seem happiest @ 2.7v

also i have tried 4708 vs 3072 and 3072 is more stable....

[xavicl]

You cant put trcd to 3 at those speeds, search the limit. I reach 280 at 2.5-3-3-5 and more than 280 need to raise 1 on trcd, so at 300 I use 2.5-4-3-7 with only 2.8V with 3/26 BIOS.

So this company (ASTAK?) is marketing a stick from one production week? I imagine quantities are limited. Pretty exciting stuff since its guaranteed to run 3-4-4-8 but I'm wonder if some of these 512mb sticks will go 2.5-4-3-6 like OPB's pair of 256mb sticks. Wishful thinking?

Did anyone using LDT/FSB? What's the best for overclocking? I see 5x at bios? It's good if i using 9x260 LDT/FSB 4x @2340MHZ? More LDT/FSB more Power?

[arctic-k20]

you want to keep the overall ht speed below 1000 - so 5x times your ram speed = ht speed

for 260 4x should be ok but much higher than that and you will need to lower it to 3x

Okay thank you very much.

I have forgotten anything. It's better to set LDT/FSB "auto" ? I read some posts and some members mean it's better for High OC and it's better if you set CPC diesable?

[arctic-k20]

cpc is 1t or 2t
enable=1t disable=2t

yes you can overclock higher if you set it to 2t but there is a performance hit
and i would choose a ldt number - not auto because it will auto to 5x and you will become unstable fairly quickly once you are over 1000

When you set AUTO, the LDT multiplier is adjust when the HTT is high.
I get multiplier 3x when setting HTT to 300MHz (LDT = AUTO)

Okay thank you but i have FSB 9x260 LDT/FSB 4x it's HTT 1040 it's also over 1000. Shall i reduceLDT/FSB on 3x and set FSB 9x270 it's better?

@kakarotto: Multiplier 3x? Isn't too bad for OC?

[mdzcpa]

I've run numerous DFI NF4 boards at 300 x 4 LDT for 24/7 use. The 1000mhz max rule of thumb on the hypertransport bus doesn't apply to the NF4 like it did with the NF3.

Just fyi.
