A quick query, i have read in a few forums that ram speed can influence the stbility and headroom for overclocking. i have a 955 at 3.7 stable and just bought the CM Scout case and Zalman CNPSX10 Extreme cooler, I'd like to think I could get to 4Ghz with this as my temps are very low, I'm just struggleing to find the perfect balance between NBV and CPUV. I have loadline cal set to 0% and CnQ disabled.

I was just wondering if their is any truth to the theory that I need to balance the RAM speed as well?

Thanks in advance

yes just try to make the ram speed at or under it's rated

ok, even with that very nice HSF, if you read the latest SBM articles you could see that even with a high quality liquid cooled rig, the 955 cant break the 4ghz barrier.

if your just overclocking with FSB, then yes, RAM speed can help with stability but you can just drop the memory multiplier down to compensate.

The 955 can break the 4 ghz mark but not all and most need alot of volts=heat=whats that smell..On my 955 OC the ram was the crashing me lots untill I got the volts right for the ram Spec timmings and speed. To the OP 1.42volts to get 3.6ghz stable on my rig have Core contact freezer heatsink max load runin prime is 53c

So you are saying that the 955 cannot break 4Ghz on water??? I hope I misunderstood your post cause I know more than 5 peeps here on Tom's that are running their 955's at over 4Ghz on air.... no water needed....

its only a waste if you have to use high volts according to the article i read

Yes but I would rather have 12GB of RAM at 3.8Ghz than 6GB of RAM at 4.2Ghz, speed difference is negligible overall and the entire system runs stock voltage no extra heat to deal with.
