Performance Comparisons
Performance of the Kingmax Hardcore Series DDR500 and DDR466 was compared to all of the memory recently tested in:New Memory Highs: Corsair and OCZ Introduce DDR550
OCZ PC3700 Gold Rev. 2: The Universal Soldier
OCZ 4200EL: Tops in Memory Performance
Mushkin PC4000 High Performance: DDR500 PLUS
Corsair TwinX1024-4000 PRO: Improving DDR500 Performance
Mushkin & Adata: 2 for the Fast-Timings Lane
Searching for the Memory Holy Grail - Part 2
Memory performance was compared at DDR400, DDR500 and the highest stable overclock that we could achieve and would run Gun Metal 2 Benchmark 2, Quake 3, UT2003, and Super PI to 2MM places. Where the data was available, comparisons were also made at DDR433 and DDR466.
Results are compared for Quake 3, Sandra UNBufferred Memory Test, and Super PI. SiSoft Sandra 2004 reports 2 results for each memory test - an Integer value and a Float value. Results reported in our charts are the result of averaging the INT and FLOAT scores, which are normally close in value. In other words, INT and FLOAT scores were added and divided by 2 for our reported score.

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
