Corsair with Abit AN8-Sli


Recommended Posts

Is the TwinX2048-3200 (2 x CMX1024-3200 v5.1) (no "Pro" or "C2") compatible with the ABIT AN8-SLi?


The reasons I'm asking:

1. I bought a dual channel pair a few days ago and plugged it into my mobo that was already populated with 2 x 512 MB O_C_Z 4200 (O_C_Z5331024PFDC-K), ie. all 4 memory banks were filled yielding 3 GB. Using Windows XP for a while suddenly caused unexplainable BSOD's. Memtest86+ v1.65 resulted in several errors.


2. So, I took out my O_C_Z RAM and ran tests with the TwinX only: Memtest showed me an error always at the same address in test #6 after running 3 complete passes for 3+ hours. Stopping the test and running test #6 specifically produced the error again, but I'm not sure anymore if it was at the same address. Increasing the voltage to 2.8 V, relaxing the timings to 3-4-4-8 (although it should run @ 3-3-3-8), and even downclocking to 167 MHz didn't change anything.


3. I placed the TwinX into my other mobo (Asus P4C800-E Deluxe with 875 chipset), and Memtest ran through it without a hickup! Even slightly o/c'ed to 210 MHz @ 3-3-3-8 (2.65 V) didn't impress the TwinX modules.


What do you suggest should I do? I hate to RMA these sticks especially since I would need to pay 15% restocking fees on something that is not broken! If you think these modules SHOULD run with this ABIT board (although they are not mentioned on ABIT's compatibility list), then I definitely have to return them since they are a no-go for me. Or is there any program where I could upgradge and pay a premium to the "Pro" version since those modules supposedly work with this board?


Thanks for reading this long posting and I'd appreciate any suggestions. I will continue with my tests, but after 2 days and 6 hours of sleep, it gets frustrating.


R. :(:


PS: I forgot to mention my setup...


- ABIT AN8-SLi with BIOS 19 (the most recent BIOS)

- AMD 3800+ X2 (2.0 GHz not o/c'ed) cooled with Scythe Ninja heatsink

- eVGA 7800GT

- Hauppauge WinTV-PVR 350 (tested with and without it)

- 465 W Enermax PSU (20 A on the +12 V line)

- BenQ DW1640 DVD burner

- Lite-On SOHC-5232K (CD-R/RW and DVD-ROM combo)

- 160 GB PATA Seagate

- 200 GB PATA Seagate

- 2 x 300 GB PATA Seagate as RAID1

- plenty of ventilation: case temps are around 30-35 C (idle/load)


I doubt that my PSU is underpowered considering that it powered a powerhungry o/c'ed P4 2.8E (@ 3.0+ GHz) system before I switched to this new mobo.

FYI, RMA means replacement manufacturer authorization, doesn't mean return and refund.

oops, you're right. as you can see from the posting time, it was kind of late :o: .


i did some more tests, and it was interesting to discover that the ABIT board set the command rate to "1T" automatically whether it's with my 512 or 1 gig sticks. is that specified in the SPD as well??? it was an accidental finding for me when i played around with memtest's advanced options. setting the command rate to "2T" stabilized the memory modules tremendously, although with severe bandwidth impact! at least i was able to work in windows for several hours w/o crashing -- huge improvement to my former 5-10 min. until the dreadful BSOD :laughing: . right now, memory tests are still running at home, though.


anyway, thanks for reading my post.
