Have you run memtest86? It'll make sure your sticks aren't faulty.

Just to let you know. Some people have been very unsuccessful getting a Q6600 to overclock on this board. I couldn't boot stable with a speed of higher than 2.7 GHz, which is really disappointing.

just be aware that memtest errors dont always mean faulty ram. Setting CMd rate to 1T will cause memtest errors on my system - my sticks are just fine though.

I tried the other 2 slots and that was no dice. I tried tweaking the voltages on all the vcore, nb, and dram. I can get it stable as long as its pretty much idle - running 3 instances hci memtest and there are no errors, but the system will lock up after a period. When trying to install programs from DVD or CD, the system will often lock up - even with just 2 gigs.

I set the DLT freq. to x3, and clocked the ram down to 667. So it appears that 4 gigs in 2x2gb dual channel mode just doesnt work with this board. :\ I have not seen anyone pull it off.

thats what was happening with mine i had a faulty ram stick

Hey guys I have a quick question. I ordered 4x1GB A-Data Extreme RAM and was wondering if there should be any problems, or if anyone had any problems with this brand. In the manual A-Data is listed as a supported manufacturer with a few models with one resembling a model I just ordered almost exactly. Looking to push the e6300 to >or= 2.5;done it before but with different RAM so fr now RAM is my only concern.
PS: Anyone foresee a problem with 4GB on XP 32bit? Except it not showing full 4GB. Thanks ahead,

[MadDogX]

Except for the usual problem of XP only showing 3.25GB of RAM there shouldn't be any problems. Especially since A-Data are on the list of supported manufacturers.

I've heard about people having problems with the yellow ram slots, but I haven't had any problems with my 4x1GB so far.


On a different topic: The ZALMAN ZM-NBF47 northbridge cooler I ordered recently for my southbridge doesn't fit there... does anyone know whether it will be better than the stock heatsink? I'm thinking about putting it there instead but the stock heatsink is so much bigger.

That isn't an issue anymore if you update the BIOS.

Just wondering.. Do you have any luck getting your Q6600 past 2.7 GHz? I couldn't stabilize past 2.7..

No, I'm afraid not. My heatsink could probably handle a lot more than 2.7 Ghz but somehow the damn board fails to post with anything above 300x9. There's either a huge FSB hole - or it's the ceiling.

A lot of people have been saying the P5N-E sucks at overclocking quads, but I'm not going to just accept that. There's got to be a combination there that makes it work.

I wish you luck then. I spent over 15 hours getting my Quad to go past 2.7 GHz. Tried everything I could think of.. Random FSB numbers to get away from the holes. Tried everything up to a 3.4 GHz.. nothing at all. One thing I noticed was that it doesn't like even clocks like 3000 MHz. You have to do like a 3011 MHz or something to get into Windows (but once in windows it crashes.. at least I get past the POST screen). I had to reset my CMOS everytime it failed (over 100 times) since it froze on the POST. Again. Good luck. Let me know what you get.
