I just bought yesterday OCZ Platinum Rev 2, 2x512mb...and I got v1.0... ;)

so, let's see the results of the "new TCCD"...

[Kasparz]

Try to increase voltage to reach stable 300Mhz@2.5-3-3-6 and show us A64 tweaker.

[masni]

update...

290htt@2.5-3-3-6@2.7V vdimm, I forgot A64 tweaker, i'll post later...

280-290- Now bring 300 home! :D

[masni]

almost there... :nono:

295htt@2.5-3-3-6@2.7V vdimm, I had to use different bios, this is with 704-2BA bios...

using a divider on this last one?atleast on tweaker and clockgen looks like it

[babyelf]

looks like the 233 divider option in the bios

[nfm]

Use:
2592 clocks tref,
dqs increase, 128
dram speed = fast

drive strength = 5
data strenght = either 1 or 2

5.5ns read preamble
trrd 3
8ns max async latency
trc 7
trfc 14
trtw 2
twtr 1
tras 5

[BioPC]

Use:
2592 clocks tref,
dqs increase, 128
dram speed = fast

drive strength = 5
data strenght = either 1 or 2

5.5ns read preamble
trrd 3
8ns max async latency
trc 7
trfc 14
trtw 2
twtr 1
tras 5
Those are as well my best parameters. When you get them working you can try lowering trfc to 13.

[nfm]

Trfc 13 only if you go higher than ~2.82V on memory otherwise it will be unstable at lower voltage. Tras 0 and lower than 2592 tref also helps on higher voltages BioPC :D. Going from 510-2FixMod to 704-2BTA helped me stabilize 2Mhz, my end result is 308Mhz at 2.5-4-3-5 with twtr 1

dqs increase, 128 helps if your on newer cpus with newer mem controllers
dram speed = fast respons to read preamble, if you set on "fastest" then read preamble does not take any effect

[harleybro]

looks like the 233 divider option in the bios
Agreed see the 117 memclk freq in A64 tweaker. Click on the memory tab on CPU-z should show you differant then 295. ;)

[RyderOCZ]

233 divider makes ram run faster than FSB, 200 is 1:1 so 233 is upclock....so 295 FSB would be like 340 ram speed, which I doubt.

[bachus_anonym]

using a divider on this last one?atleast on tweaker and clockgen looks like itIt's div120 selected from BIOS therefore only DDR354 :hehe:

[MaxxxRacer]

Guys i think its a bug.

If you look at his clockgen it says -295....

[masni]

sorry guys, when I flashed new bios, i used bios reloaded settings and my ram was set to "BY SPD"... :banana:

i didn't realize that at all... :rolleyes: so, 295htt doesn't count...

but here is a new clock, 300htt@2.5-4-3-7@2.7V vdimm

<a href="http://imageshack.us"><img src="http://img252.imageshack.us/img252/677/300htt25437superpi32mb2yc.jpg" border="0" width="1024" alt="Image Hosted by ImageShack.us" /></a>

i'll use your tips and report again... :toast:

[lawrywild]

yay nice 300htt :D

[|SiLA|]

Guys i think its a bug.

If you look at his clockgen it says -295....

i had that bug when i used 9/10 "180" so .. :rolleyes:

[RyderOCZ]

Thanks for the update Masni Nice Clocks !! :woot:

[nfm]

I believe those tccd hold much more potential, you should be humming 2.5-3-3-0 twtr 1 trc 7 trfc 14 at 300Mhz + easily with them. This is what I got on cheapo tcc5 Rev.2 v1.1 after many hours of tweaking:

http://img.photobucket.com/albums/v298/Kapucyn/PC/Best32MCalc.jpg
That's an absolute max without a doubt.

Or maybe new tccd aren't that good as before...

[[XC] moddolicous]

Masni, nice results. TRC should be 10, and twtr should be 1. Those may give u some nice results.

[masni]

another update... :cool:

@need.for.mhz

i couldn't get this ram pass superpi 32mb over 290htt@2.5-3-3-6, this is the max, 2.7V vdimm, rising vdimm didn't help... :(

maybe you have an idea, or a tip... :toast:

[masni]

this isn't over yet... :nono:

this "new" TCCD is really good... :clap:

[dogsx2]

Where did you get them?

[CRUSH-ER]

My TCC5 1.1's from August do 308 or more stable at 2.73v at good timings but I'm running them now memtest stable at 253 (DDR 506) at 2.84v at 2.0-3-3-6 due to a poor memory controller. :rolleyes:

[masni]

Where did you get them?

Croatia, Europe... :)

Here in croatia we don't get very good mem sticks, there isn't any gskill, patriot, crucial to buy... :(

there will be another upadte, i feel... ;)

[althes]

very nice sticks keep the updates coming.

[skycool]

hi , masni. i have same couple ocz with you , the v1.0. and same m.b. ,3000+.now i put it on 300htt, 1:1,at 2700Mhz,stable. just like before you did. but i can not set it at 310htt, i need your help............
could you shot some pics. from your bios's memory configuration?
i need know :Drive strength: ? ,Data strength: ? and some else information can not be find in your a64 tweaker. thanks
i use 623-3 bios.

Your CPU isn't at 1.45, it's ay 1.48. Nice results btw, I want this ram o bad but decided that going with a 2gb kit is uhhh, smarter, I guess.

[CRUSH-ER]

You should change your LDT bus from 4x to 3x man. :toast:

[jahjahbinks]

DRAM RESPONSE = fast?

Mine can only POST at normal.

[masni]

@Dave_Sz

vcore is set to 1.425 x 104% = 1.44-1.46 , so i wrote 1.45... ;) not so important... :p:

@CRUSH-ER

why...?? 300x4 = 1200...that is not the max of my mbo...i makes no difference if i use 3x or 4x...only when i go past 320htt i use ldt 3x... ;)

@jahjahbinks

that depends on your ram...my chips are a little better...that's just luck... :toast:

[nfm]

hey nice results, try decrease dqs, I've made mistake and told you to use increase. Should say dqs "Faster" in A64tweaker and trrd is a big stability factor, especially 3 clocks and if you go higher max async latency may be changed to 9ns and tref set to lower than 2592, good luck. Also get to the point in memtest where you see errors in pass #5 let's say your'e at 320Mhz with current setting and get ~100 errors, tweak every tming and see with which one you get least errors and continue to up mhz

[CRUSH-ER]

It's usually best to keep the LDT at 1000 or less.

[ex2cib]

not a bad set of ram. if my mem controller wouldn't have gotten tired of high mem frequencies i would try to beat your 2.5-4-3-7 32m.

just curious, but whats the highest you can go 2.5-3-3-7, 32m and also max bench speed?

1.425x 104%=1.482. Also, the boards max ht is 2000, yours is now at 2400, 300x4x2=2400, you misssed a step.

[Vapor]

Dave....the board never supplies the exact voltage specified in BIOS, the only way to know what you're getting is to check with a DMM. Also, if his board runs perfectly fine at 1200, then let it be, no sense in pulling it down to 900 if it doesn't need it. :stick:

And don't mulitply it by 2....that's marketting BS because it's full duplex, it still runs at 1000.

[uOpt]

I did the multimeter trick and I found that my SLI-DR is extremely close to what I select in the BIOS (and that the sensors for the OS are off).

Forget about the HT, it's no biggie. Actually, when I run my ht above spec, my music encoding or whatever it's called is a bit faster. The only reason I said that it actually runs at 1.48 is because, well, that's what mine does. I have minet at
1.375x101%. All my software shows it at 1.47-1.48 when it should be 1.5125. Ok, so I took out my DMM, a 77series fluke, and guess what, it read 1.512. So my board seems to be supplying the exact power that the 1.375x110% should. That's why I said what I said. I guess not all the boards are the same.

[masni]

enough of OT... :nono:

let's get back to memory tests... ;)

i have another update...this is my max stabile setting, pass 317htt i have to change some settings, maybe loosen up something to get higher clock...i didn't rise ldt voltage or chipset voltage, maybe this will help...

and also, i will try my sticks one by one, to see witch one is better (if there is a better one... :p: )...

318htt@2.5-4-3-5@2.8V vdimm...

i think i can push this sticks a little bit more...or at least i hope so... :clap:

i'll get back soon... :cool:

[MACMAC]

Very, very nice!

Hope my stuff can come close to yours! But I doubt it because the A8N-SLI Premium doesn't have nearly as many tweaking options as the DFI.

I would die for Drive/Data Strength, DQS and Tref options in the bios! (You hear me Asus!!!)

Anyways, I'm still tweaking now, mainly testing for 2.5-3-3-6.

What was your highest clocks using 2.5-3-3-6?

i reached 290htt@2.5-3-3-6...:(, but to be honest, i didn't try them any further...

i wanted 300htt+, so i used 2.5-4-3-5 timings... ;) later i'll try again...

[MACMAC]

Ah ok.

For the last...oh...5 hours I've been tweaking things, and I think I've got it stable at 295Mhz 2.5-3-3-6-12[Trc]-14[Trfc]-3[Trtw]-3[Twr]-1T

No matter what timings I tweaked, I was always getting 24 errors.

That's when I found out that multipliers make a bigger difference than I thought.

7X and 2.7V would give 2 errors in Test #5, but 8X and 2.7V would give 8 errors. 7X and 2.75V would give 0 errors, but 8X give 24 errors. Tried upping the Vcore from 1.4V to 1.45V, but still 24 errors.

So I just set it to 9X and 1.55V, and it works fine :p:

thank you so much masni. my 3000+ and tccd are working better,
and i wanna know which bios do you use when you get 310htt@2.5-4-3-5@2.7V and higher than that, like 318htt?

i can get in windows at 310htt , or 315htt. but not stable. :mad:
maybe you change something in bios but i didn't :confused:

need know your experience. :p:

i used 704-2BA bios to hit 300htt+...

this timings is stabile up to 318htt, after that, i used 2.5-4-3-7, trrd 3, 9.0ns max ansync...

thats it...enyoy and report back with some fine results... :toast:
