Guyz just need some clarification, does the overclocking suffer if we use Triple Channel kits on a P55??? I have got my P55 setup running for just a day now, and though I havent tested them thoroughly but my GSkill Trident 1600 CL6 kit which could do 2200 Mhz CL9, is not able to boot at somewhere around 1850 CL9 from the initial impression. So some1 who has tried this, can explain this?? or should I put more effort and this should work???

Mem speeds are tricky on p55, I think as bios mature it will get easier.
What board and chip are you using?

From what I've read, sub-timings are important on the P55 boards to maximize performance. Not sure if you sticks have a different set of programmed sub-timings that could be effecting your over all top speeds.

Splave, using a UD4P board here.....seriously do not want to spend on another kit since I will be only using either x58 or the P55 rig for regular use as well....will play with the subtimings, thanks for clarifying about the timings thing, and I was thinking why does the board does not boot when I am trying manual timings, it boots only when using auto timings....

Should be able to push farther on p55... mainly because you have too.

have read the article in the morning when it was posted, but he is using separate dual channel and tripple channel kits as far as I can tell....

Nope

Same kit

DDR3 2×2GB (and 3×2GB) from a Kingston KHX16000D3ULT1K3/6GX kit


Sorry I can't add anymore than that.. I have not run a p55 yet.

OMG!!! I clicked on it, opened it but the title made me feel that its the same article that I read earlier, looks like its completely different. Thanks a lot looks like this is what I was looking for......

I remember asking this long ago and was told it should make no dif using 2 sticks of a triple channel kit on a P55 system.

I usually purchase triple channel kits so I can use these sticks on both setups. Marketing might want you to believe that they are different and there for you should buy a different kit for each setup so they sell more RAM.

I think what we see when clocking RAM on a P55 vs X58 is the fact you are using 1 more or 1 less stick of RAM. With 3 sticks timings become more critical than with 2 sticks. Remember when we used to clock on older setups that we generally went for high OC's with 2 1gb sticks on a platform vs a 24/7 rig that uses 4 2gb sticks.

Clocking memory is a fine art, so many settings that generally most do not know how they effect things.

As motherboard/CPU/Memory setups all act different spending some time with Memtest, adjusting settings and seeing the effects with our benching programs is worth while.

Yup completely agreed, and I actually knew this but it was my impatience and since I feel at home here hence without even trying much I posted the question. After Neuro's article played around a bit and it seems there is some sort of link between QPI/DMI and Ram. I was setting QPI/DMI to the lowest multi and then trying to OC ram but looks the simple logic of x58 where Ram multi has to be double or more of QPI is not true? Had to set the QPI to a fairly high multi which made it work...

Back to 2200Mhz CL 8-9-8-24, will play around with sub timings later.......
