Hi all,
i want to ask about 32-byte Granularity. is it important to disable with tccd?
Thanx.
TCCD/TCC5 discussions, memory tuning, voltage, etc.

QUOTE(sniper69 @ Jul 11 2006, 07:20 PM) hy there...i'm new here with new (traded with vtec rock his TCCD), i actually hit DDR670@3-4-4-8@2.8VDimm (not stable thou), DDR660 Super-PI-ed 32M, n DDR630 stable after memtest n Super-PI-ed, wonder y Priming failed after 10minutes even after i lowered the CPU multiplier as low as 6x (300x6), 400x6... wow.... DDR670.... i'm curios to see this. can show ur screenshot? |

QUOTE(leadaxer @ Jun 17 2007, 12:43 PM) Ok, thanx for the input. But my concern is NOT how much or how far this baby can go. It is purely simple. Assume that: I think, u dont want your TCCD exceeding 2.8v. And, in my exp., i havent met any tccd will do CL3. Resulting in no-boot. n oso from my exp, tightening TCCD sub-timing will benefit little gain in perf. Unless it can boot with " Bank-Interleave" option as ENABLED in bios, then it will be in the same league as BH5 / CH5 / BH6 (of course w/ higher frequency than the later).- Timings can be very loose: 3-4-4-8 - Vdcc can go anywhere from 2.6V up to 3.2V - Multiplier is locked And judging from the specs of the said RAM: Team Xtreem Hermes DDR1 PC4400 DDR 550MHz 512MBX2, 2.5-4-3-7, 2.7~2.9V That would make it have a standard clockspeed of 275MHz. My question is, could it make 280MHz without much of a sweat..or is it near the absolute limit already...? The tightest sub-timing of TCCD can give me around 29s in superpi 1M ( thats at oced to ddr600). n The tightest BH5 (yeah, Team Zeus Series) comes at 27s (oced to ddr500 only). Both at same config,same setup; 3G Opty 146. |

wow... chill out dude. Just telling,
1 - tccd cant stand high voltage. That is, if u want it to last longer. 2 - BH5 is better for benching well in ur case, there's no assurance how high it can be oced. if u want to achieve ddr 560, y dun just buy ddr600 rams? And, for ram, there's always "Burn-In" procedure.But it very risky.Wrongly burned, u'll end up stuck w/ setting the time u burned. Well, if u want to take the risk, go through high-reputation forums, xtremesystems,ocau, to name a few. There's always a guide for it. mine achieved abt 20mhz after burn-in, 2 notch lower vdimm n tighter timings. |
