JPM has mentioned a few times he feels the IMC is the limiting factor of his memory clocks. I was referencing his wall for memory frequency, not the IMC. Remember the IMC is also responsible for memory frequency... The Edition 10 has a layout optimized for BW-E, so should help him on the memory side in comparison to the R5E.

daaum - that's very sharp... all it needs is a thin film OLED screen in the top glass or heads-up like display. very cool!

So far with each of my kits the R5E is behaving better with the BW-E than HW-E. I had 3 HW-E chips in this MB at various times, all behaved similarly which is to say they could run at 2800, 2800 or 2800... I did eventually get 3200 with 1/2 my 128G kit in a benching setup with HW-E, but not something that would pass an hour of stressapp.

So, it appears the OC socket is dead for BW-E as it relates to unicore frequencies owing to BW-E cache architecture.

Pretty fascinating/sad that we are getting to quad-pumped 12GHz effective DDR technology-wise (GDDR5x) Where intel is running a 2.8GHz on-chip cache... and yes I know latency, burst, access vs cache-line on-chip and DDR vs GDDR is a different beast, but still 11-12 vs 2.8-3.7 is a BIG difference.

Cool! Didn't know these existed. Might have to check this out as I use my case kind of like a desk (Ikea tabletop and two monitors on top) ... thumb.gif

Not as big as a Cross Desk, but big enough and almost half the price here in the UK. Lots of room inside, as well.

That might well be the case, but the Edition 10 is better than the R5E for clocking memory.

I'm not hung up on cache frequency. The power trade-offs were always unbalanced for my liking.

Hmmm - just checked it out - do you have to be on Facebook to order? Too big for my use unfortunately.

For my daily driver use cases it provides a linear speed up 10% more cache speed provides 10% more application performance but I admit it's not the usual. I've already got custom loops so provided it is stable and not chip roasting voltage, I'm more than happy to move the heat away for that.

Interesting on 10 as I can say the same for DDR speed of course lower CAS is just as important, I definitely see the bump there. 2800@12 beats 3000@14 but of course that equation changes with 3200 or 3400 provided the CAS stays low.

Anyone that understands memory should never talk about timings as if they are a separate entity to frequency.

Being UK based, I ordered mine from OCUK.
