Kingmax Hardcore PC.
Kingmax Hardcore PC-4000 2x512mb
We received the Kingmax memories in two separate gold boxes, one for each 512 MB stick. The box is a bit large, and is actually more for the inner piece of plastic that holds the memory inside stably. Inside the package you can find the memory itself and a small product catalog containing the variety The products that Kingmax sells. The memory comes with green aluminum heat sinks, which are uniquely designed and slightly different from most other memories on the market. This is not a drastic change, but it's always fun to see some companies try to refresh cosmetics in the world of computers. It was worth choosing a different color that would suit the more unique motherboards that the market has to offer.
The green heat sinks can be removed very easily, without any utilities, which means they are not as reinforced, and probably less efficient at dissipating heat from the memory chips. Also, the model sticker is affixed on the side of the clamps and not on them, so there is nothing to fear from its tearing and loss of warranty. Beneath the heat sinks can be seen from a kind of simple thermal pad, but it is not sticky and does not leave a mark when removed. After removing the heat sinks, the DT-D5 Hynix chips can be seen on both sides of the memory PCB.
The following are the memories, according to the product page on the Company's website:
-Performance range V233Mhz / 250Mhz (4.3ns / [email protected]= 3)
Power supply: VDD: 2.7V¡: 0.1V (for DDR500
-Bi-directional data strobe (DQS)
-Differential clock inputs (CK and CK #)
-DLL aligns DQ and DQS transition with CK transition
-Auto & self refresh capability (8192 Cycles / 64ms)
-Double-data-rate architecture; two data transfers per clock cycle
-Programmable Read latency 3 (clock)
-Programmable Burst length (2, 4, 8)
-Programmable Burst type (Sequential & Interleave)
-Edge aligned data output, center aligned data input
Serial presence detect with EEPROM

The factory default memory timings are 3: 4: 4: 8, operating at 500MHz at 2.7V. These are relatively loose timings, but the truth is that we were able to reach lower timings, and higher final speeds, as we raised the tension of the memories and tested what maximum performance could be obtained from them.
