OCZ TCC5 Overclocking Results?

[high5]

yes, only stuff on label is relevant here.

[Ein0]

So my ram sticks are tccd if they have no 1.0 or 1.1 on the sticker?

[high5]

yes.

[mrapples]

@ein0, where did you order yours from?

[mrapples]

anyone have new plats that are tccd to confirm this?

[ex2cib]

ive put this in bachus anonym's highest TCCD thread also, but thought i would put it here since its TCC5
9x295 @ 2.5-3-3-7 32m stable
618-3 bios

[ZX7891]

nice results

The fastest 2.5-3-3 Superpi32M stable TCC5 I have seen

But still far far away from 305

Bump the volts and you may be the first to reach 300 and definitely the TCC5 record holder. Keep trying.

[LikwidKool]

I have some pc4200 Plats TCC5 which are at 300x9 at 3-3-3-10-1t 2.8v right now. I passed test #5 for 7 passes real quick just to make sure. Unfortunately my cpu will not run super pi 32m at 300x9. I have a venice coming soon so hopefuly I'll be able to get that. Timings are not super tweaked as I have only had these sticks a short time.

I only added the sandra pic for the tweaker shot. Like I said these settings are untweaked. I need to play around a little more.

[ex2cib]

i should get a chance to play with them a bit today, as right now there is a tropical storm outside.

i think im going to have to drop the multi down to 8, CPU is starting to max out, and i dont want that to have any effect on the mem clocks. i tried to change to 2.5-4-3-7 last night and see how high i could push 1m...only 3 mhz more than 2.5-3-3-7. at 2.5-3-3-7 310 i can run 1m, changing trcd to 4 only got me 3 more mhz.

what is the record for TCC5 anyways?

[ex2cib]

i tried dropping the multiplier to 8, same exact situation, only 3mhz more in 1m. so either the mem controller has reached its limit, or there is some setting i am missing.

how much would upping the LDT voltage and chipset voltage by .1v help? each of those are on their 2nd value from the top in the bios, whichever those are.
i might try disabling bank interleave, dont know if it would help at all

[amrgb]

ex2cib, try the following
- max async latency: 9
- read preamble: 6.5
- Trc: 12/14
- Trfc: 16/20
- Tref 2336
- Vdimm: 2.9v (3.0 if you want to take the risk)

Also, try -2 bios. Unlike it's common to hear, it's the (one of the) best for TCCD.

[ex2cib]

i tried 2.9, actually ended up worse than 2.83. i think 2.83 is where i need to keep it, seem to get the most out of it there. now my highest 1m on my ram is around 313-314

[ex2cib]

highest 1m was exactly 314, using a few of your settings and mine amrgb. im trying a 32m right now at 298.

what are your chipset and LDT voltages?

[dnottis]

DDR630 @ 2.8v still testing. OCZ PC4800 with TCC5.

[nfm]

Nice dnottis, could you do me a little favor?:

What's the max 1:1 HTT@2.5-3-3-7 with these settings:

- trc 12 clocks
- trfc 18 clocks
- trrd 3 clocks
- twr 3 clocks
- twrt 2 clocks
- trtw 3 clocks
- read write queue bypass 16x
- bypass max 7x
- max async latency 8ns
- read preamble 5.0ns
- idle cycle limit 256 clocks

find your best voltage, tref value and data strenght and lets see if you can hit 300, 1:1 HTT, or can you get 32M super pi stable at 1:1 HTT@2.5-3-3-7 300 HTT? You have a great venice there, also try 2.5-4-3-7. Thanks

[amrgb]

highest 1m was exactly 314, using a few of your settings and mine amrgb. im trying a 32m right now at 298.

what are your chipset and LDT voltages?

I set both to +0.2v above the normal values. I think that these voltages aren't too important. I only set them to +0.2v to rule out these two factors.

PS: the settings I used for 305 2.5-3-3-7 are on the link in my sig and the complete list of memory timings is here http://www.xtremesystems.org/forums/...949#post937949

You can try with my settings as showed in here:

http://www.xtremesystems.org/forums/...chmentid=32415

You could start from 300Mhz @2.9v and raise just the clocks.
Tell me then about your max stable fsb achieved.

I'll do it tonight after work - as for Super PI - she's already super Pi stable. I'll try what you want to see and get some more screenshots up tonight of the TCC5 results.

[ex2cib]

ill try to work on it sometime tomorrow if i get time

[Harshal]

After reading some of the TCCD/5 info, OCZ Plat REV 2 are TCC5 currently, right?? Also, If I have EPOX 9NPA SLi is it safe to predict 290MHZ+ or a DFI Lanparty SLi-D will help cross 300??? Or its just simple plain Luck??

I have A64 3000(Winne)
MSI RS480MSIL (Upgrading Soon to EPOX or DFI)
Twinmos CH-5 512X2
Corsair TwinX1024-3200V6.1 (Suposedly Winbond-BH)
OCZ PowerStream 520W

I am also getting OCZ Plat Rev 2 if reply is somewhat good. I am looking for something under $185 (shipped).

Thanks.

[ex2cib]

i wouldn't go so far as to predict 290+, i have only tried 1 pair of these, and mine work great, but i can't say the same for others. it depends some on your CPU.
it seemed when OCZ first started using TCC5, the results weren't that great, but they seem to be getting better from what i can tell.

[STEvil]

its highly dependant on the CPU.

the PC5000 parts from every manufacturer are very high RMA rate, and its not the ram causing it for example..

[Harshal]

Ok thanks for the help. But what will be the max I will be able to get from them, if I get them??

[mrapples]

i think his point is that you cannot know that answer, it depends on the memory and the cpu
