BIOS hangs during post

Question

Well I decided to start a new topic on my continuing problem. I reinstalled my memory in the correct config. (DIMM 1 and 3) but it still hangs during POST. I cleared NVRAM, cleared CMOS settings and reloaded the defaults. I have counted the number of times I have to hit the reset button before it decides to load. It is usually 3... I am at a complete loss as for what the problem is. When it works, it works fine, but more often than not, it hangs and the LEDs on my DDR hang also...The memory is brand new so that's not a problem. This might be more of an annoyance than anything that I can fix, but I really don't  understand...

Answer 1

Yes, all corsair RAM is warrantied to 2.8V, except PC4000 and above, which they warranty to 2.9V. If you wish to clarify this with them direct then read or post here
I think there is a compatibility problem with this chipset / memory combination, please read:-

I suspect that PAT is playing a part in this, but you need to confirm this via BIOS.
In Frequency / Voltage Control
Do you have Performance Mode: Slow.
If so, I would try manually setting timings:-
Advanced Chipset Features
DRAM Timing Setting
Configure DRAM Timing by SPD: Disabled
CAS Latency: 3 Clocks
RAS Precharge: 4 Clocks
RAS to CAS Delay: 8 Clocks
Burst Length: 4 Clocks
Integrity Mode: Disabled
and see if you can post.
Second thing to try is just one memory module at a time and run Memtest on each and see which errors.
If you still can't post at relaxed timings, see if trying some NoName PC3200 memory does the trick!
Unfortunately, the only DDR400 Corsair Memory Modules listed in this mobo's Compatibility List is the CMX512-3500C2PT and I have a feeling I've read somewhere that the a fix was implemented on these modules to ensure compatibility.
I would post on the Corsair forum, and see if you can't persuade them to swap your modules for a more compatible type.
The benefits of Low Latency memory on the 865 / 875 chipsets (all manufacturers) are the subject of much debate anyway and whilst opinion is as ever divided, I am firmly in the higher frequency is better than lower latency group.
Hope this helps.
