i just can think 1 solution if u guys going to use heatspreader for the rams. Use non-conductive aka mx-1 thermal grease.
It's sure look goods, but, heatspreader are meant for high vdimm one aka bh5 / ch5. Ive been running my bt-d43 253@2-2-1-11 1T 2.9v back while. it didnt get hot ( as hot as need some cooling ). Just my 2 cents.  |

Actually i agree with satanhead....It's sure look goods, but, heatspreader are meant for high vdimm one aka bh5 / ch5. Ive been running my bt-d43 253@2-2-1-11 1T 2.9v back while. it didnt get hot ( as hot as need some cooling ). Just my 2 cents.  i've been pumping 2.9v to my DT and BT-d43 and they dont feel hot..  WArm yeah .....thats why i decided to just get a fan blowing at it, even though i dunt think i need it... coz my top blow hole is already aligned nicely on top of the ram.... ohh well... |

i never did burn my 1GB sitcks of d-43 eventhough they were at 2.9 volts during my NF7-S days
and no matter how much voltage you give d-43s, they will never budge from max of 240FSB for my pair.....sheeeeeeesh =.=" |

QUOTE(RacingTech @ Mar 30 2006, 08:24 PM) Hello guys, I just bought the AIR value ram which using Samsung TCCC chipset on it, i wonder how much juice can we push on this baby??? At the moment i only manage to push it till 250mhz which = DDR500 with 3-4-4-8 timing. Is there any where to push it futher like....275mhz???? QUOTE(RacingTech @ Apr 3 2006, 07:25 AM) Thanks for your complement lichyetan Bro...sorry to dissapoint you but i dont think you got a Samsung Chip on your rams. , my cpu is also venice core but may be i'm not lucky enough to clock it high with default heatsink. I am thinking of getting a good heatsink like ninja n see how it perform. As for the RAM, i think it is good enough for me, but like zahri say, is like possible for use to use thermal paste on the heat speader n removing the default thermal tape??? Is any one out there try that before???Btw have you tried reading it with Everest or CPUZ? |

Antonio_zth,
It is a Samsung TCCC cause it is a value ram and you can see the chip!!! Although in cpuz you cant see it but physically it is a Samsung TCCC!!! If not, what chip do u think??? |

about heatspreaders.
i actually tried once, removing the heatspeader, the tim between the heatspreader, lapped it, then clip it back to my ram. it's a corsair xms heatspreader, the one that uses the thin strands of metal for clipping, somthing like paper clip, so i managed to get most contacts between the chips on the ram and the heatspreader. used some arctic ceramic (silver is conductive, i tried to stay out of troubles..) for extra contact. to test it out, i used memtest for burn in. i cant remember the results coz i forgot to note it back then but.. roughly... without heatspreaders 2-3-3-5, 2.8v, reached 240fsb stable at 245, got few errors every several loops of memtest, roughly 1 or 2 errors per 4/5 loops. with direct fan blowing on bare rams, 2-3-3-5 2.8v 250fsb stable, 0 errors after 8hrs, removing the fan instantly produce errors.. with heatspreaders. 2-3-3-5 2.8v 240fsb stable. 2-3-3-5 2.8v 245fsb, no errors for 10pass, then loads of errors. - the heatspreaders managed to remove the heat fast enough when the ram modules arent really hot. but after heated up, seems like it cant dissipate the heat fast enough to cool down the module, ends up heating the ram. heatspreaders with fans. no problem running 2-3-3-5 2.8v 250fsb for 8 hrs.. takes sometime to produce errors after removing the fans, but generates more errors per loop compared with bare heatsinks. i cant seem to push it higher with the same timings, possibly the limits of the ram at that timing, or bcoz pat was enabled.. didnt bother to disable and test it bcoz of the performance difference is too much with pat disabled. so, imho i'd say that even with proper contact, heatspreaders dont have enough surface area, or heatsinks to help dissipate enough heat, especially without airflow. even with airflow, it is not really efficient. just sticks with bare rams + fan. as for the difference between the heatspreaders with their default tim and arctic ceramic, i'd never actually did any comparisons, but i can bet that with arctic ceramic the heat can transfer to the heatspreaders faster since it heats up a lot faster, compared when using thermal tape, or the original tim. tim = thermal interface material. |

ermm...
so its better to run the rams bare with a fan then with heatspreader.... |

QUOTE(antonio_zth @ Apr 4 2006, 02:25 PM) Bro...sorry to dissapoint you but i dont think you got a Samsung Chip on your rams. yeap..indeed u are rite.Btw have you tried reading it with Everest or CPUZ? actually AIR OEM ram with samsung tccc chips are Mosel Vitelic 5ns ram chips that are re-labeled. read this, QUOTE Vitelic 5ns - This is 5ns ram from Mosel. It is commonly found in PC3200 offerings, and at this speed is rated at cas2-3-3-6. This is not bad, but nothing out of the ordinary. It is similar to CH-5 from Winbond. This ram can clock to around 240 MHz and hold decent timings such as cas2.5-3-3-6. If timings are kept at 2-3-2-X, then this ram will typically max out around 220 MHz. This can be found in Corsair XMS3200, Geil Ultra PC3200 and PC3500, OCZ PC3200 and PC3700. This is not a bad choice of ram at all. It offers great overclockability while still holding very respectable timings. Although Mosel is not a well known name in the memory industry, you can see that the top memory manufacturers are using their ram. If you can get these on the used market, they would make a very sweet deal. I have not seen these in Value Ram offerings, but that does not mean they do not exist. Identifying these can be somewhat difficult, as many companies re-label them. Take a look at the ram list to be sure of what modules contain these chips. You can identify these chips by the last 5 characters being SAT5B. picked from atomicmpc.com |

Hi antonio_zth,
i will try the everest tonight, i didnt know that ram can be relabeled. Thanks for your information. But i dont think it is a big deal cause it can reach 250mhz then i am happy with it since it is a value ram. GKwong. Since you are a AIR owner, how about the chip on your ram, is it true that it is a fake samsung??? R u using the everest to test it? |
