TCCD DDR600+ DFI nF4 Ultra/SLI guide

[kakaroto]

Yep kakaroto Pi 32M rock stable !!!

Great!! I cannot do 32M fully with my Clawhammer 3500+.. Hopefully with a better controller on the 3700+ SD

Good job!

Thank you very much man

Now with 510-2

A64 Venice 3000+ @ 2.4GHz 300x8 1.525v
1Gb G.Skill PC4800LA @ DDR600 2.5 4-3-5 1T 2.8v

I tested my system in Memory Bandwidth Benchmark (SiSoft Sandra) and I get only 6680/6628 in the 1st. run and 6686/6620 in the 2nd. run.

It's terrible... isn't it?

What could I change? What setting is the problematic setting?



My Venice is REALLY a bad overclocker.
What voltage can I put in LDT and Chipset with no chance of getting any problems?

Thanks

[higherøx]

510-2 gave me so much better results
I could get the same results, but with more agressive settings and less 0.1v, going from 2.8v to 2.7v.
With other bios I couldn't pass memtest stable with 315FSB even with 2.9v, with 510-2, I almost passed this goal with 2.8v, but I got 2 errors in memtest #5, can you help me?
I'd like so much using 315FSB with 2.8v, because I'm not sure if I could use 2.9v daily.

Settings for 300 FSB 2.7v:




When I got 2 errors in memtest86 315FSB 2.8v, the settings were (in order):
2.5
04
06 (05, 07 and 08 = worse)
03
14
16
03 (or 02-02-02-02 was the same)
03 (or 02-02-02-02 was the same)
02 (or 02-02-02-02 was the same)
03 (or 02-02-02-02 was the same)
3072 (4708 always were better, but with this bios it isn't)
01 Bus Clock (better than Auto)
Enabled

Auto
0 (255+ = worse)
Level 7
Level 2
8ns (9ns = worse)
Fast
5ns (Auto = worse)
256Cycles
Enable
16x (8x was worse/the same)
07x
Disable



Pleae help me!! I'd like 315 FSB 2.5 4-3

Anyone with Ocz PC3200 Rev2 memorys who using 510-x ? I need a good setup and should i use Tref 3072 also? Have a DFI NF4 Ultra-D and a SD 3700+

[jikdoc]

@kakaroto,

i read in a post by ocz tony that running a system under phase increases the drive strength so that you need to lower it in order to overclock well. have you noticed this with tccd? i'm running gskill LE @ 287 2.5-4-3-7 on SD now. 2.5-3-3-7 won't go at 275 and above

Uhm no. I also have a LS but the TCCD results on air and Phase are here the quiet the same.

When Timings are tighter then stronger drive strength come handy.
When looser the timings then you can try lowering the drive strength.

Remember, when upping the drive strength you may lower the Vddr to make it stable.

With TCCD I always use drive strength 7 and data strength 2 with Vddr 2.7v. With BH5/UTT I use 7/8 and 1/2 (depend on your ram test results)

[XiN]

So 510-2 (with 3.16 ram table) is better for TCCD?

Anyway, at the moment my best is DDR630 7-4-4-2.5 spi 32M stable (with 2.9V and bios 510-3)

PS: with a CBBID

Good question that I want to know, too.

I don't know if I use 510-1, 510-2 or 510-3. G.Skill 4800LA.

I heard that 510-2 is better for UTT, but I'm not sure.

Thanks, []'s

510-2 is suppose to be for UTT/BH-5 (510-1=TCCD, 510-3=everything) but I've seen several people use it with TCCD also. Personally I didn't notice anything even though 510-2 let's you use both the orange or yellow slots for dual channel. I had to go back to 310p for it to OC stable.

[higherøx]

So, I have TCCD I think I'd use 510-1... hummm

[XiN]

Isn't 510-1 generic and 510-3 for TCCD? Uhm ... just little confused

Anyway, I'll try 510-2 too

[kakaroto]

nope, with 510-3 you can use orange and yellow slots because this bios is two memory table compatible.

For UTT/BH5 the best bios is 510-2 and TCCD/TCC5 best is 510-1.

Ok, thx

So this http://www.techpowerup.com/articles/other/114 is wrong ...

(* -1 for both kinds of rams, -3 for TCCD etc., -2 for BH5/CH5 etc.)

I just can't get my G.Skills stable at 300 2.5 4-3-6 with 2.6v

[Murdock_TF]

Hi everybody here,

I'm new in this forums, i watch you a long time and now i said; i must join the community

My Problem is the following:

Systems Specs.:
DFI NF4 Ultra
1GB OCZ Platinum Ed. Rev. 2 with Samsung TCCD 440 Chips on it
Athlon 64 3200 Winchester
X800XTPE

I wanna get 300Mhz @ 2,5-3-3-6 stable, but i can't get it. I tested a lot of confÃ:banana:gurations but nothing bring 300Mhz fully stable @ 2,5-3-3-5. FarCry chrashes after 15Min. but Memtest did 30Min. without errors.

Here are my setting in Bios:





can someone tell me what i should change, but i didn't want to change TRCD to 4

[xavicl]

These memories cant do 300 at 2.5-3-3-5 , i can only do 278 or so. And 305 at 2.5-4-3-7 (2.9V)

[higherøx]

Agreed.
My G.Skill's Samsung 440 just CAN'T run at 2.5 3-3.
And it was not easy to reach the total stability at 2.5 4-3-6 1T 2.7v.

[Transonic]

Well it's kinda like they said ^ it's hard enough to get G. Skill to do 2.5-3-3 @ 300 let alone Platinum Rev.2, try 2.5-4-4 instead. I spent the better part of yesterday morning trying to get 290 & 300 FSB to pass memtest and I got pretty damn close with these settings while at 2.5-3-3-7 but 2.5-4-4-7 was what got me to pass:

Genie:
290-300 FSB
3x HTT
9x Multi (10x hasn't worked for me yet)
1.55v Startup
1.4v
113%
1.3v LDT
1.7v NB
2.8v RAM (little or no errors compared to 2.7v in memtest, 2.9 showed no improvement)

DRAM Config:
200 1:1
2.5
4
7
4
10
14
2
2
2
2
1032 (4708 was a close 2nd best, I tried just about all of them)
1
enabled
increase skew (auto & 0 gave me a bunch of errors)
255 (tried 200, 100, 50, the lower the # the more the errors)
Level 7
Level 2
8ns (slightly more stable than 7ns)
5ns
256 cycles (everything stock from here down)
disabled
16x
7x
disabled

I'm chillin at 260x10 atm cuz it's rock solid without distortion on my screen. I'm gonna RMA my graphics card probably this week which, according to BFG, should clear up the crap on the screen. If that doesn't work then my CPU is next. I'm also gonna try to flash my bios again now that I got some good/stable settings to try. Currently I'm running the 310p bios. Hope this helps.

1.55v Startup
1.4v
113%

Why?

I ever used 1.4v at startup that's my default, I did it wrong?

Thanks

Well that didn't really make much of a difference for me, I was kinda emphasizing on the DRAM configuration settings/timings rather than voltages.

[higherøx]

Which gives the better performance for TCCD, Skew Value 255+ or 0 "Auto"?

And which of them give better stability?

I can explain to you, but OPB has a much more and clearer article about DQS.

[higherøx]

Thanks
Other thing that's interesting is that trrd, twr, twtr and trwt were running here at 02-02-01-02, I just couldn't pass SuperPI 32Mb, then I put 03-02-02-03 and I didn't lose much performance but reach the stability.
Data strength for TCCD: I know that Level 1 and 3 are more stable, and 2 is better for UTT and BH series. But here Level 2 gave me stability. But what is FASTER for TCCD, Level 1 or Level 3?

Thank you

Start post is updated with San-diego memory stability tweaks

If anyone has more findings about the Venice and/or San-diego please share here. thank you!
