| 1187144 | 2011-03-29 23:31:00 | I have had a number of boards that put the memory timings and value at wrong setting even though they are running at default.....I have had to force the settings....and usually its the memory voltage... running at 1333 instead of 1600 is a common occurrence, however Im a little out of the loop now.. |

| 1187145 | 2011-03-30 00:15:00 | I don't really know either, I don't overclock, I'm using the cheapest RAM I could find, DDR3-1333 from eBay which at the time was $70 cheaper than anything in NZ. | Agent_24 (57) | ||
| 1187146 | 2011-03-30 00:37:00 | Try this (www.overclockers.com). Same stop error. It may have something to do with the voltage settings Altho that applies to the P55 chipset As one of the posts says: When all 4 DIMM slots are occupied on a P55 board, as in your case, the QPI/VTT voltage (or IMC voltage) needs to be increased because of the added strain on the memory controller even at an effective / rated DRAM frequency of 667MHz (DDR3-1333; 133 BCLK x 10). The absolute maximum VTT as spec'd by Intel for the i5-700 series chips is 1.40V, so just keep that in mind. You might be able to get by w/ the default 1.05V PCH Core voltage (the P55 chipset), but I would just leave it at 1.14V which is only a .09V increase over the default. |

| 1187148 | 2011-03-30 01:16:00 | yes 2 4G, 2 empty slots. I did try swapping them around before this thread started. 25 hours crash free, have reverted back to a previous windows install to avoid activating again ( must be up to around 4 times amazed it worked last time ) and turned the onboard LAN back on, will let it run like that till tomorrow and then try the RAM voltage back to 1.5 again. As far as I can tell from corsairs webasite and my BIOS the auto setting has set the RAM as per the SPD like it should. However the need to increase the voltage would tend to suggest it's working harder than designed or is faulty. My suspicion is still that its a problem to do with the way sandybridge interracts with RAM because of all the posts I find with the same issue on other hardware. The Geil forums have a user attributing it to their RAM for example and fixing it by upping the voltage.and over on ASUS forums they are blaming the P67 pro MB. Random freezes, looping audio, and screeches coming out of the speakers - seemed like I was reading my own problems but the hardware is completely different - except the chipset..... also read through the posts from speedy's link, sounds intriguing. Perhaps sandybridge has a weak memory controller or is just finicky with RAM, and perhaps 8G in 2 slots is enough load to cause issues, QPI voltage is not the same as the DRAM voltage though right? Seems the earlier advice to check the supported memory list was on the money, however CL has NONE of the listed memory modules available and neither does PBtech. they have other modules from the same manufacturer though... |

| 1187149 | 2011-03-30 01:20:00 | True, it looks like that XMP may not be reliable either (when its enabled) | Speedy Gonzales (78) | ||
| 1187150 | 2011-03-30 01:33:00 | I've never gone by RAM QVL, because like you found yourself, you can't find the RAM for sale, but only time I had problems was if the timings were set wrong or the RAM was DOA. I have seen a lot of threads where people bought Intel-certified RAM for their AMD system and it gave problems, though. |

| 1187151 | 2011-03-30 01:55:00 | Thats why I asked about the QVL, I got a ASUS mobo w\ PhIIx4 w\ 2x2Gb and the damn thing would lock, restart, freeze etc. Voltage was incorrect, but it would run correctly either even when overvolted for the correct speed. CL sent me QVL RAM and the problem was solved straight away! Its like they give you 2 speeds for the RAM, pick what works for you! |

| 1187152 | 2011-03-30 18:56:00 | I have turned everything back on and just left the RAM voltage as the only change. Currently on 10 hours uptime so it seems like that's the one. Now that I know what to focus on I may try a few other RAM related settings. |

| 1187153 | 2011-03-30 19:04:00 | Sounds like it could be the RAM, but like its been mentioned - it may not be faulty, just not completely compatible with the Board. | wainuitech (129) | ||
