Kingmax Hardcore Memory: Tiny BGA Reaches For Top Speed

Kingmax DDR466 Hardcore Memory
DDR466 was also provided as a matched pair of 512MB modules.
Except for the speed rating of the DIMMs, the Kingmax 466 and 500 modules are exactly the same.
Apparently, chips for the next bin level are used for DDR466. As you can see, the memory chips are rated and labeled 4.4 ns by Kingmax. This is consistent with a DDR speed rating of 466.
Kingmax DDR466 Specifications
| Kingmax DDR466 Memory Specifications | |
| Number of DIMMs & Banks | 2 DS |
| DIMM Size Total Memory |
512 Mb 1 GB |
| Rated Timings | 3-4-4-8 |
| Rated Voltage | 2.6V +/- 0.1V |
Kingmax 466 Hardcore memory is rated at the same voltage and timings as their DDR500. We were a little surprised that Kingmax did not choose to rate DDR466 for a bit faster timings than their DDR500. However, in the past, Kingmax has been very conservative in their memory specifications. Generally, they claim that the rated timings are the worst you will see on their memory, with most DIMMs performing significantly better than specifications.

By the way could you guys please start highlighting the item being tested in the graphs with a different colored bar or even different color text for the name (or both)? It makes it very difficult to find the product you are testing if I have to read every name on the graph just to find one of them.bldkc - Friday, March 12, 2004 - link
Wow, don't buy the DDR466! On page 6 it took 1114 seconds to complete! Okay, it's a typo, but still.#10-If you wear a thinner coat outside you won't stay as warm as if you wear a thick one. The same thing with chips.

#11 - Corrected.#10 - BGA chips are both much smaller and thinner than TSOP chips. The electrical connections are also much shorter, generating less heat to start with than TSOP chips. I have seen data supporting 80 to 85% heat dissipation with BGA chips.

I sure hope Kingmax didn't provide you with 512K chips of RAM ;). (top of pg3)ViRGE - Wednesday, March 10, 2004 - link
What is it exactly about BGA chips that make them run cooler than TSOP chips? There's the size difference of course, but that doesn't account for the temp difference, does it?Jeff7181 - Wednesday, March 10, 2004 - link
It's good to see this from Kingmax... I've been wondering for quite some time now why video cards have had DDR500 memory for a few years, and it hasn't made it's way into system RAM. Now we have RAM on video cards capable of DDR1000... why can't we get similar results with system RAM?Inferno - Wednesday, March 10, 2004 - link
Something everyone may want to note, if you decrease voltage on the Kingmax sometimes that yeilds better O/Cs then raising it. I have owned alot of Kingmax TinyBGA and it usually responds negativly to more voltage. They also do benifit from heat spreaders when pushed hard and kept at default voltage.Pumpkinierre - Wednesday, March 10, 2004 - link
Good article but still more of the same. It seems like 18month old Winbond BH5 and now these BGA chips are the fastest at DDR400-433. However, are there any hints of a DDR466-500 at low latencies (CAS2) out there? I mean graphics cards have got 256Mb of <3ns DDR (dont know the latencies) so why arent the memory manufacturers using that?Xtreme DDR have got some PC3700+ at 2-3-3-6 using picked 5ns Samsung chips (http://www.xtremeddr.com/products/x_pc3700+.shtml)... They quote 2T command rate and some i875 mobo compatibility, which is counter to the Mushkin website advice that intel dual bank chipsets force 1T timings, and memory rated above 1T could be unstable. Perhaps you might get a coupla sticks of that and put them through your test procedure?

Evan,We have achieved ludicris speed, overshot the winnebago, and gone to plaid.

BGA is the new standard on DDR2. I welcome the change.Kristopher
