Corsair has been one of the biggest memory module manufacturers since 1994. Their XMS product series is designed for the unique demands of the serious enthusiast community. XMS stands for eXtreme Memory Speed. The XMS family includes XMS2, high performance DDR2 modules, XMS Xpert (the first modules with real-time display of
parametric data), XMS Pro Series (gaming memory with real-time activity LEDs) and XMS
Classic with black or platinum heat spreaders.
In this review, we will be testing the XMS TwinX 1024-3200XL RAM modules, part of the XMS Classic series with black heat spreaders. These DDR memory modules are clocked at 400MHz.
Corsair uses Samsung's K4H560838F memory chipsets for its Memory modules. The K4H560838F is 268,435,456 bits of double data rate synchronous DRAM
organized as 4x 8,388,608 / 4x 4,194,304 words by 4/16bits, fabricated with
SAMSUNG's high performance CMOS technology. Synchronous features with Data
Strobe allow extremely high performance up to 333Mb/s per pin. I/O transactions
are possible on both edges of DQS. Range of operating frequencies, programmable
burst length and programmable latencies allow the device to be useful for a
variety of high performance memory system applications. Below you can see a list of features for these chipsets.
- 200MHz Clock, 400Mbps data rate
- VDD= +2.6V ± 0.10V, VDDQ= +2.6V ± 0.10V
- Double-data-rate architecture; two data transfers per clock cycle
- Bidirectional data strobe L(U)DQS
- Bidirectional data strobe(DQS)
- Four banks operation
- Differential clock inputs(CK and /CK)
- DLL aligns DQ and DQS transition with CK transition
- MRS cycle with address key programs
- Read latency 3 (clock) for DDR 400
- Burst length (2, 4, 8)
- Burst type (sequential & interleave)
- All inputs except data & DM are sampled at the positive going edge of the system clock(CK)
- Data I/O transactions on both edges of data strobe
- Edge aligned data output, center aligned data input
- LDM, UDM for write masking only (x16)
- Auto & Self refresh
- 7.8µs refresh interval(8K/64ms refresh)
- Maximum burst refresh cycle : 8
- 66pin TSOP II Pb or Pb-Free package(RoHS compliant)
