TCCD DDR600+ DFI nF4 Ultra/SLI guide

[S0nic]

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.

did u have to raise ldt voltage from 1.2V? or the chipset voltage from 1.5V? because afaik it's not a mobo issue, it's a chipset issue..

[SET]

hello.

I have problems here. I have tried the configuration as Kakatoto says, but cannot cause that this works correct. Actiualmente I obtain these results on 3/10.P.

Somebody can say please to me that I must change or that I am making bad?

Thank you very much

[arctic-k20]

try chaging:
trfc=14
trc=9
max async=8ns
idle cycle limit=256

and are you sure 1.4v is enough for you cpu @ 2500mhz ? might need a smidge more

[SET]

My configuration is:

Vcore: 1.550 + 104%
LTD: 1.2V
Chipset: 1.5V
Vdimm: 2.9V

Profit to obtain 2,6 Ghz with these adjustments, but does not finish the PI 1M. T

hat but I can do?

Thanks

[arctic-k20]

trrd=3
tref=200mhz 3.9us

also try andyocz's vcore trick - set vcore to 1.3 and set 123% - try those settings and see if it helps!

trrd=3
tref=200mhz 3.9us

also try andyocz's vcore trick - set vcore to 1.3 and set 123% - try those settings and see if it helps!

why 1.3*1.23% = 1.6V and no using 1.4, or more and 1.13 or 1.1 multi? is is worth to use 123% multi, any advantage?

[arctic-k20]

because it has been noticed that the vcore doesnt track properly when using 1.5+10% etc so if you drop it down to 1.3~1.4 and use a higher % you may get the vcore to scale up properly and get your cbbid to o/c

[SET]

Bad news.

I have tried all the possible configurations and this does not want to do 260 x 10 @ 2.5-3-3-x I have thought to change my memories by a UTT, can be good election?

Thanks for everything.

I'd like to say a thank you to the thread starter for providing this information. I used the settings listed for DDR550 with 331-3 bios with my G.Skill PC4400 LE modules and It's running perfectly. I will post some screens when I get home. But I'm very happy with what I have so far. The board worked perfectly right out of the box with the 1/25 bios also. But I'm glad someone posted some manual settings that work well. Thanks a bunch.

[GNU]

I use the settings @DDR550 but not 550 only 540 because if i try to set the FSB up to 275 or 280 at the same settings. Memtest shows too much errors.
At next i use the same settings @DDR600 but not 600 only 540. I can't set the FSB up
to FSB280. I have no idea. I want to run FSB 280 but it's crashes every time.
Can you help me.

[GNU]

I tried to use different settings but nothing runs. Any idea?

[Huhn]

thanks for this nice guide running my tccd adata 566er 2x512mb @ 300mhz cl 2,5-4-3-7 2,7v now. runs flawlessly and rock stable. without thta guide, even 300 mhz with 3-4-4-8 were not stable at all

Glad it helped alot of people here

=========
Guide is updated with a small change.
Tref 3072 is better then 4078 for 24/7 stability.
=========

Trc = 8 sometimes helps for better stability in memtest86++. Not confirmed by me. Thanks Tutti-fruti.
=========

Another thing:
Q:
My memtest session test5 is doing fine 200pass+ butwindows is not stable. (prime etc)
A:
Try up 0.1v.

Please give us more info to help you. What kind of CPU are you using and what kind of RAM.
Thank you.

Sorry i have forgotten it.

Bios 310P (testing now)

After my post about Memtesterros. I have tested with 2.5-4-4-8 @280. It runs but not long. I tested with Memtest. It's okay then i tested with Sandra and Prime95 (long FFT 3h). It's okay but i tested first time the torture test BLEND (Prime95) it shows me an error. Another problem is if i play a game like Silent Hunter 3 (This game need very high memory) then my system crashes. My system doesn't run @2520 Mhz. And i want reach FSB 280 - 290 stable WITH 3-3-6/7/8 (anything but Trcd 3! It's faster and i read many posts about Tras. It's better 8 than below 8 but i want to reach fast settings without any lost of data) I can't solve my problem.
Ah yes i tested with Memory Analyzer (this program crashes while testing).

Summary all settings are not 100% stable.

For anyone using this guide: Remember, every rig OCs differently from the next, even if the hardware is identical. With this in mind, change each timing individually from the rest using A64 tweaker in Windows. You can then test for stability using Pi or 3DMark once the setting has successfully been established by A64 tweaker. This way if your system has a strange quork (ie can't run Trp of 3 above 250MHz...pretty uncommon in my experience) it can be singled out without going through an unsuccessful post if you were manually setting all the timings at once in the bios. Just something to keep in mind, even for the veterans out there (we all make dumb mistakes.)

GNU:
Try using 1.325v + 136% special and the 166MHz RAM divider. Then boot at 260htt or so and see if you can't scale to 290...Seems to me like your mem controller just can't hang at those speeds.

Here is what I run 24/7 with my OCZ PC4400 Hynix and 0449 3000+

Also, from all the testing I've seen, a Tras of 6 is the most efficient setting for the NF4.

@Gogeta: Thank you for your information. I haven't any problem if i set FSB down to 270/260. It's stable with 1.3v 123% 2.5-3-3-6 but if i set this up to 280 then the system crashes. So i have tried with 4-4-8. At the beginning. I have no problems with many Testprograms but after 4x reboot then the problem began. I can't believe it's my mem controller because it runs 2 days 280 without an error. I will test your suggestion.

[GNU]

So i tested your settings but it's not stable. My system crash while i play a game like Silent Hunter 3 (very high memory and cpu stress). So i see nothing want to run stable NOTHING. Every settings are not stable. I can't believe it. Many users have the same settings 2.5-3-3-6/7/8 or 2.5-4-4-8 but my system want it and crashes. Most settings passes Memtest without any errors but in windows ..... (One times it's prime error, one times it's Memory Analyzer and most of errors ARE IN GAMES! Many BSOD. It's maybe a defect Mobo or bad IRQ?

Try Bios 2-17 GNU

[GNU]

Bios 217 is older than 310 what's better in 217?

[Gogeta]

Hmm, could be your mobo but it sounds like the limit of the cpu. I would switch to the 331-3 beta bios and see if things improve. They did for me.

[fareastgq]

Bios 217 is older than 310 what's better in 217?

Well, I've tried them all, and no matter what, 2-17 gives me 0 HD corruption, I can oc like hell and I never worry about it, it's the only bios that lets me run high fsb or tight timings, tccd or utt, 3dmark stable, if the other bios's are not working for you, this is prob the bios for u, you may be in the same situation as me, that's all, every rig is a bit diff, g'luck. As to technically what's differnt, I don't know, heh, ask oscar wu/tictac, someone who mods bios's

Wow. Then i will test 2-17 and i hope it can stop my crashes about HDD Backup. I give you a short explain of my new problem. I tried to backup big files (3gb) from a IBM IDE HDD to a SATA Seagate HDD. While the transfer my system hangs up. Every time and this problem cames suddenly. I getting more and more and more problems. Ramsettings are not 100% stable see the other posts over me and then it's my HDD.

[neokenzo]

Anything above 260Mhz, I cant use 2.5-3-3-6. Above 260Mhz, I can only 2.5-4-3-6 without any errors. Anyway of getting 2.5-3-3-6 above 260Mhz? Here is my settings at the moment:

Vddr: 2.7v
Tcl: 2.5
Trcd: 4
Tras: 6
Trp: 3
Trc: 9
Trfc: 12
Trrd: 2
Twr: 2
Twtr: 2
Trwt: 2
Tref: 3120
Twcl: 1

Bank int.: Enable
Skew control: 255 +
Drive strength: 7
Data strength: 4
Max. Async: 7ns
Read Preamble: 5ns
Idle Cycle: AUTO
Dyn. Counter: Enable
R/W Bypass: 16x
Bypass Max: 7x
32Bit Gran.: Disable

So i have solved my problems until my HDD problem. I uses 2.5-3-3-8 FSB260x9 LDT 4x @2320Mhz and this runs stable in all Testprograms even in games but i want more Mhz. I can't believe FSB260 is the maximum Clock for my CPU. I hope i can set more FSB stable maybe until 280. Any idea to change my settings?

I don't test Bios 2/17
