Heres a though for all of us that had Memory probs

So from what I understand the Bull Dozer has a significantly different memory controller. So all the work we did with the Denebs to get the memory to work and hours to weeks of overcolcking to fast and stable conditions will be a mute point if we upgrade to the B.D. ? It will be like starting all over again ? Geesh Cant wait ..

Anybody have any projections of the initial cost of the B.D. upon release ?

Bulldozer should have a stronger memory controller, so hopefully it will be easier.
Asus Maximus Extreme Z, Intel 2600K at 4.5, Noctua NH-D14 cooler, MSI GTX 670 PE/OC, Dell U2412 monitor, 8GB Gskill Sniper memory at 1866, Corsair HX850 Power Supply, Asus Xonar Essence STX, Samsung 128 gb 830 ssd, WD RE4 2 tb X 2 in raid 1, Intel 320 870 gb ssd, Filco Tenkeyless keyboard, Logitech G400 Mouse, Audioengine A5 speakers, HP Officejet 6500 printer

It is more about trace/signal optimization then Bulldozer having a stronger IMC. The 990 boards are designed for Bulldozer with compatibility in mind for earlier processors. Future AGESA releases will make memory clocking harder when using current CPUs.

At least with Thubans using the tools at hand can result in respectable speeds still being achieved. I see an average of 15% higher memory clocking and approximately 150MHz NB speed gain when properly tuning the C5F compared to the C4F. Drive Strength adjustments play a key role in reaching full stability when pushing memory/NB speeds. Also need to keep in mind the relationship of VCORE, CPU/NB, NB and HT voltages to each other and what changing these voltages is actually doing. Altering any of these voltages also changes the corresponding timing window. Examples are noise threshold, jitter and clock crossings. When on the ragged edge a change of 0.005V can mean the difference between not booting into Windows and complete stability.

Fro pre-Thuban processors I prefer the C4F. On that board AGESA is tuned for those CPUs and the same clocks will not be reached on the C5F. In the end I guess it is all about setting our expectations realistically within the limitations of the components on hand and fully using the tools we have to get the most out of those limitations.

Praz.. nobody explains it like you.. thank you.

Sir, Have you done any testing with the dom.gt1866?
Do you have an idea of why it isnt on the qvl?
Is there something I'm not seeing...or did I just
get a lucky t1100/ram combo?
Hate to be ding'n on this question, but just trying
to figure out why some are on it...well that wont run, and
this isnt.
(I still point to JJ's OC Vid w/t1100/dom.gt.1866..my video,
using t1100/7130mb of 8000..and of course Chew/FX/dom.gt.1866/WR/1 stick,no.1 lane)
I await your respected answer...thanks.

I actually got better memory and CPU overclocking results with my 1090T on the CH4F.

So much so, I've been tempted to rank my CH5F and replace it with my trustworthy CH4F until BD arrives.

Actually peoples should not purchase a board until the CPU is release no ? Especially we don't know how perform this CPU.

I don't have any Dominators to test with. Normally memory not being on the QVL doesn't mean it will not work. Just that ASUS has not tested the memory with the board.

To surpass the C4F requires patience and tuning. If one doesn't have the time for this then the C4F is the better option.

So again, any projections on retail release price ?

I want to talk about it also this morning but....... I hope the main reason it's not yet release is because they try to have a better quality of yield.
