TCCD/TCC5 Overclocking Database and Discussions

Having overclocking problem with your TCCD? Some questions that we usually overcome with TCCD and TCC5 chips.......

So... I hope this is the best thread to share our results on TCCD/TCC5 discussions. I don't see any relevance in separating TCCD and TCC5 as they are basically the same chip/ic, which is Samsung K4H560838F. To make this database possible, you guys need to post your best DDR speed which is stable enough to run SuperPi 32M. Don't forget to include your CPU-Z verification link. Necessary utilities like SuperPi mod and CPU-Z 1.30 is provided at the bottom of this posting.

Categories are divided to single channel and dual channel. 2x dual channel will be added if there is any. AMD or Intel does not matter, as long as it fulfills the requirement. Ranking is sorted according to the highest DDR speed, followed by timing and then voltage. Lower voltage will have better advantage compare to higher timing.

Rules
Just like any other database, please include your:
1. CPU, chipset and FSB:RAM divider used.
2. RAM brand, TCCD or TCC5.
3. RAM speed, timing and voltage.
4. Screenshot of SuperPi 32M (pass) with 2 CPU-Z which shows "CPU" and "Memory" section. Please use thumbnail or attach to the posting to make things neater. Avoid direct image linking if possible.
5. Include CPU-Z verification link.

Example:

http://valid.x86-secret.com/show_oc?id=41342
CPU: AMD Sempron 2800+
Chipset: nF3 250Gb
Divider: 5/06
RAM brand: 512MB OCZ EL DDR PC-3200 Platinum Rev.2 1.1 (TCC5)
Speed : 270MHz, 2.5-4-3-10 @ 2.8V
*Ignore screenie, it's just an example of posting template

This database purpose is to help others, rather than for show-off purpose. Each person can post more than one result, as long as it came from different brand. There is no need to cheat to get into the chart, as there is no minimum ranking for this database.

Utilities:
CPU-Z v1.30
SuperPi mod 1.4

no luck yet so far.... but it's getting interesting

will restart from the scratch

what i like about my TCC5 is that it runs DDR400 2-2-2-5 with only 2.6V, 100% stable with memtest, prime and superpi32M

i wanted to try 2.5V but when i put 2.5V the reading is still around 2.6V

but heck... the default voltage OCZ suggested was 2.75V

no much luck yet

i can do DDR600 2.5-4-3-7 at 2.8V with some errors during memtest. can run superpi 1M and run sisandra memory benchmark only

maybe it's just my Palermo D0 memory controller at the limit

TCC5 is binned at 466MHz by Samsung
TCCD is binned at 500MHz by Samsung

both are from the same die (revision F), which means they should have the same overclocking potential.

lower speed binning actually reduces manufacturing cost

got such tccd ddr600 2-2-2-5 meh?

i tot... tccd ddr600 2.5-3-3-x-1T is already super

and also... CL1.5 by Geil also marketing gimmick, where the CL1.5 is actually non-existence in A64 memory timings

Geil sure got lotsa marketing gimmick eh?

My current setting at 2.8V with very minimum error in Memtest86+, maybe need more burn-in

(Using DFI nF3 250Gb 4/15 BIOS w/ 4Vdimm mod)

haven't tried that though

i tot lower timing is more stable

nice one there dude

but 256MB modules sure can clock high easily due to the single bank factor

ahpaul... i think your voltage is too high for only 270mhz ler...

try back down to 2.7v or 2.8v

yours are tccds right?

find your maximum memory oc and tune the memory timings to get memtest86 pass at test #5, tune until you can get it run at 2.8V or less. if you're trying to run at 300mhz, put the vdimm at 2.9v

from there, after you can pass memtest86 #5, try to enter windows. if you cannot stable in windows, you might need to increase your chipset, agp or cpu voltage. or maybe u need to bump your agp speed to 67mhz. no need to alter your vdimm anymore.

bios memtest purely tests the ram, that's why even OCZ still use this utility for testing.

when you go into windows..... any memtest based tool is affected by the processor and overall system stability also, that's why you can pass bios/dos memtest but cannot pass windows memory tester.

One reminder to TCCD/TCC5 users, do not stress your RAM with high voltage like 3.3V and above, if not the RAM will lose their efficiency with lower voltage. This matter had been discussed in a few other forums.

my ocz EL tcc5 can do 200mhz 2-2-2-5-1T with only 2.5V

maybe u need more cpu voltage

i don't think there's any KVR with TCCD chips because TCCD are considered premium chips... not value chips (expensive production cost)

TCCC, i'm not so sure whether it's quite good or not. but the best one i've seen is only around 250mhz, but most of them can do only around 230-240 with loose timings.

you can find TCCC in some KVR and Apacer Value

1T of course

anyway... this thread is meant for DDR600 TCCD and TCC5only... so let's back to the topic

ah_khoo

it's better to find your limit by running at 1T

.....coz 2T is gay on DFI

the extra memory option is not that hard. first you try to get some settings that has been regularly used by everybody, but make sure the type of mobo and ram that is used is similar to yours. for example u might want to find a setting that is similar to somebody that is using lanparty nf3 ultra-d with TCCD. from there u just test 1 by 1 on the options that different ppl use different values. for the options that most ppl using the same value, just leave it that way.

that's the method that i used to reduce my RAM voltage from 3.2V memtest stable to 2.9V memtest stable, on my TCC5 of course.

It depends whether your processor can cope with up to 300mhz DDR or not, unless you can run the DDR with ratio higher than the FSB, which is not possible.
