Hubird Posted September 1, 2008 Share Posted September 1, 2008 I read the post about P45 chipsets and 1600 RAM troubles http://www.asktheramguy.com/forums/showthread.php?t=71781 I seem to be having the same problems except with 2G not 4. I have the latest BIOS (BETA :[pouts:) and am unable to get my PC to boot with the RAM spped at 1600, seems fine at 1333. I must admit though I find this boards BIOS overly complicated, if anyone has a similar setup that is working I would appreciate some pointers (I am open to suggestions).

Hubird Posted September 1, 2008 Author Share Posted September 1, 2008 I have been unable to get my system to boot with my 1600 DDR3 RAM running at 1600 So I just download and ran CPU-Z and got some weird results. Memory SPD Module 1 DDR3, PC3-10700H (667 MHz), 1024 MBytes, Corsair Module 2 DDR3, PC3-8500F (533 MHz), 1024 MBytes, Corsair Also different part numbers: CM3X160C9DHX CM3X1G1600C8D4 I would have thought that the part numbers and speeds should be the same (it was a sealed pack), did I get a bad batch ?

Hubird Posted September 2, 2008 Author Share Posted September 2, 2008 I found someone with a similar problem (different RAM / SPD info) http://www.asktheramguy.com/v3/showthread.php?t=68645 I will take the RAM back to the shop and try to get it exchanged for the 1600C7DHX 2x1g kit which will hopefully run at the advertised 1600 speed.

You need to overclock the FSB to 400Mhz to attain the advertised 1600Mhz speed. Link to comment Share on other sites More sharing options...
Hubird Posted September 3, 2008 Author Share Posted September 3, 2008 The problem is that when I overclock the FSB to 400 the PC will not even POST. That's when I came across the link about P45 / 1600 RAM troubles, I am assuming that I am having this problem (as well as my RAM not being matched pairs).

Hubird Posted September 3, 2008 Author Share Posted September 3, 2008 Just an update: I have given up on trying to get my RAM to run at 1600. No matter how I adjusted the settings in the BIOS I could not get it to POST. I have had 4 different packs of the Corsair CM3X160C9DHX (2x1G) RAM. First lot did not seem to be matched (according to SPD info in CPU-Z, and M/B BIOS), exchanged that for another lot that was matched but still would not POST at 1600 (both sticks say a maximum speed of 533 MHz, (1066 DDR ) now :sigh!:). I then went back to the computer store and asked if I could exchange my RAM for the more expensive 1600C7DHX 2x1g kit (and pay the difference) but they would not because I did not keep the original pack. I then exchanged the RAM once again clinging to the hope that I might get a pair that worked.. Boy was that a mistake !!! This pair had one stick that was dead, so after much pleading and arguing I got them to try some another brands 2x1G RAM in my board (and replace my faulty RAM while they were at it). The other brand RAM did not run at 1600 but did show up as supporting 1333 in the BIOS. Long story short, I give up....I'll settle for 1333 !! Even though I told them about the official post here explaining the troubles, they kept insisting that it was something in my BIOS configuration.

Hubird Posted September 16, 2008 Author Share Posted September 16, 2008 Thanks for the offer, I was building the PC for someone else who moved interstate. He is content to have it running at 1333 and uses it for business so will not mess with it any more. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 16, 2008 Corsair Employees Share Posted September 16, 2008 Were you dropping the CPU multiplier when setting the FSB to 400MHz? Link to comment Share on other sites More sharing options...
Hubird Posted September 26, 2008 Author Share Posted September 26, 2008 Yes I dropped the multiplier to a value that gave me a clock speed that was close to what the CPU should run at standard. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 26, 2008 Corsair Employees Share Posted September 26, 2008 More than likely the BIOS will be updated that will take care of that, but if he has problems have him call as I suggested and I will help him get them replaced.
