'New' CellShock 1600 CS3222271 2x1GB (D9JNL ?)


I now have slightly better CL7 clocking than I did, but 900mhz is the maximum I can find for Memtest stability.

Max vDIMM before errors start is 1.90V (set in BIOS). So 900mhz/CL7 and 1000mhz/CL8 seem the limit for 86+/HCI.

CL7 up to 950mhz is mostly ok for 32M with ~ 1.96V.

Can get to windows / run Everest at CL7/1000mhz but can fail at any time.

However even if the max, 900mhz/CL7 opens up more of the board than the Transcend could - 562FSB/5:8/899mhz isn't great at CL8/tRD9, but starting to get pretty quick with CL7/tRD8.

For Read and Latency, 560+FSB/5:8/CL7/tRD8 takes over nicely from where 475/1:2/CL7/tRD6 gets to, and the board takes the strain instead of the DIMMs.

CS3222271 works ok with 0206/0403. 1001 seems good enough to keep using it with this kit.

could work as 4x1GB @ 800-900mhz/CL7, but not enough CL7 headroom for 2x1 on this board.

Using CS3222271 @ 1.90V, I have made a bit more progress with Blend, Large FFT and IBT stability at 500fsb/1:2/CL8, adjusting GTL and DDRref in line with some of cstkl1's recent recommendations


All Voltage set in BIOS 0403/1001 (not measured)


Memtest HCI 2000% / 900mhz (1800) / CL7 / vDIMM 1.89V / vNB 1.40V







475x9.5 / 950mhz / 266strap / CL7 / tRD 6 / CT Strong / vDIMM 1.96V / vNB 1.51V







562x8 / 899mhz / 333strap / CL7 / tRD 8 / CT Mod / vDIMM 1.90V / vNB 1.59V






I've included a quick IBT run aswell but more work needed for a longer test. vNB may go lower.
