Never knew that GEIL made single sided ddr2 pc6400 ultra 4-4-4-12 RMA'd 1 set of GEIL DDR2-800 CL 4-4-4-12 GX22GB6400UDC (2x1GB), I wanted to RMA all my 4 ram sticks but they did not accept that. Now I found out that my 2 new ram sticks have a sticker on the heatspreader it which reads: Voltage 2.0V My other GEIL set DDR2-800 CL 4-4-4-12 GX22GB6400UDC (2x1GB) has a sticker on the heatspreader which reads: Voltage 2.1V Also when I looked closely I found that the pcb/transistors are different from each other. Ok, probably they changed the pcb design? And the ram sticks are manufactured in another week? Suprisingly when I open CPU-Z all 4 ram sticks: Week/Year 10/08 The new set won't run 960MHz 4-4-4-12 either, while the other set can. Also with every new GEIL ram stick I found a thin plastic film sticked on the GEIL logo, the "new" set of ram that I just got returned only had this on one ram stick and there was no plastic film on the other stick. Also I had a problem with the Voltage in the BIOS, my older ram stick rated at 2.1V I always had the Voltage at +0.5 which resulted in 2.3V, now with the new sticks rated at 2.0 I had to set the Voltage at +0.6 to get to 2.3V. After trying different timings and speeds , at one moment the BIOS settings went back to auto and now when I would set the DIMM Voltage +0.5V results in 2.3V again with all 4 sticks in it. Somehow I don't feel so good about these new ticks that I got returned(Thailand), the PCB design/transistors are different and the rated voltage is different, and manufactured in the same week as my older ram sticks to me it looks like FAKE geil sticks? Or just cheap pcb's with a orange heatspreader and GEIL logo sticked on it? Now I run my 4 sticks at 5-5-5-10 960 2.0V (the voltage is not bad but they used to run 4-4-4-12 960 2.3V) the new ram sticks seem to be low quality If anyone ownes GEIL DDR2 800 4-4-4-12 sticks, could you post a picture and week/year from your ram sticks?
