Ah, the age old question of 'How much memory do I need' crops up time and again on many enthusiast forums from users seeking advice. This simple question cannot be answered in a 'one for all' scenario as a lot depends on the type of programs you run. If you are an avid photo shopper or indeed work with audio and video then the old adage of 'too much is never enough' applies. However for the average household, we have previously proven 6GB to be more than ample for an everyday setup. With prices of DDR3 dropping however, 12GB is now becoming within reach of every ones budgets and here is where Kingston step in. They are now providing 12GB kits that are cost effective no nonsense kits which should eradicate the headache of the user looking to future proof their setup.
12GB kits are fairly thin on the ground at present due in part to the high prices DDR3 demand. Those prices however are beginning to drop and to further the attraction of 12GB, Kingston have released a value kit which comprises of (2x) 3x2GB totalling 12GB. The price of such a kit is sketchy at present but I did manage to find a 6GB kit on Sale in the US at $113. Multiply that by 2 and using the present currency conversion rate equals a price of £141.42 for a 12GB kit. Not too shabby but perhaps not as big a bargain as one would have hoped for. Still, when you consider many were paying that much a couple of years ago for a high performance 2GB kit of DDR2 then this puts the price into some form of perspective.
Here's what Kingston had to say about their kit:
ValueRAM's KVR1333D3N9K3/6G is a triple-channel kit of three 256M x 64-bit 2GB (2048MB) DDR3-1333 CL9 SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR3-1333 FBGA components per module. Total kit capacity is 6GB (6144MB). The SPDs are programmed to JEDEC standard latency 1333Mhz timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers and requires +1.5V.
The following specification was taken directly from the Kingston
JEDEC standard 1.5V ± 0.075V Power Supply
667MHz fCK for 1333Mb/sec/pin
8 independent internal bank
Programmable CAS Latency: 6,7,8,9
Programmable Additive Latency: 0, CL - 2, or CL - 1 clock
Programmable CAS Write Latency(CWL) = 9(DDR3-1333)
Burst Length: 8 (Interleave without any limit, sequential with starting address “000” only), 4 with tCCD = 4 which does not allow seamless read or write [either on the fly using A12 or MRS]
Bi-directional Differential Data Strobe
Internal(self) calibration : Internal self calibration through ZQ pin (RZQ : 240 ohm ± 1%)
On Die Termination using ODT pin
Average Refresh Period 7.8us at lower then TCASE 85°C, 3.9us at 85°C < TCASE . 95°C
PCB : Height 1.180” (30.00mm), double sided component
CL(IDD) 9 cycles
Row Cycle Time (tRCmin) 49.5ns (min.)
Refresh to Active/Refresh Command Time (tRFCmin) 110ns
Row Active Time (tRASmin) 36ns (min.)
Power 2.160 W (operating per module)
UL Rating 94 V - 0
Operating Temperature 0o C to 85o C
So on the outset, nothing too outstanding other than the massive total storage of 12GB. I do however wonder how much life a product such as this has left when you consider 3 and 4 GB modules are now available to buy.
Let's take a look at the packaging and appearance of the product...
