Great run! :up: I did some testing (but it was hot to finish) and 4.7GHz is about lowest possible for 200GFLOPS run.Quote:

thanks dom :D
i think that 200gflops depends from the ram, because before when i was having gskill 2133 @ 4,7ghz i was having 193gflops, changed ram and bumped to 2.4ghz they i had 200gflops :)
and no it's not snowing, i've just opened my room windows ehhe :D , i tried to run this morning 4.9 ht off, reached the 13 loop i got an error, and temp where pretty high so i decided to let it go, i'll try when room temp is lower, don't really want to rma my board again! :mad:
btw here is a 4.9ghz ht on :)

And finally I've got my replacement board, but I'm faced with the exact same debug 01 issue. What are the odds for me receiving my second faulty Rampage IV Extreme motherboard?
Once again I tried with different pairs of RAM, running one-by-one, trying with two different graphics cards. Basically I tried with different kinds of every piece of hardware besides the CPU as I don't have a second LGA2011 CPU around.
Now the big question is, might I actually have a defective CPU, which are very seldom or did I just receive my second faulty Rampage IV Extreme?
Wow that's terrible. I'm inclined to think cpu at this point.Quote:

Those are safe voltages.Quote:

well from what I've read even Sham suggested upto 1.15 VCCSA for 24/7 use on the rog forums, granted I'm sure one can push higher with water and other cooling solutions but with air I simply do not see why it would go so high on auto?Quote:

if vccsa is 1.05V, the vcore should not exceed 1.35v, right?
thanks :)

So you're right!:)Quote:
If overclocking past DDR3-2000, then finding the optimal delta between CPU vcore and VCCSA becomes critical with some memory modules. Hence, we recommend making small changes and monitoring for impact upon stability. It is probably wise not to exceed a voltage delta larger than 0.6V between VDIMM and VCCSA, so if VDIMM is set to 1.65V, then set VCCSA at around 1.05V minimum as a starting point AND also try to keep VCCSA within 0.3V of Vcore if possible.
ok thanks
my settings (bios) ram @ 2400
Vcore 1.28v
VTT: 1.15v
VCCSA: 1.05v
VDIMM: 1.65v
it's all good :D
Auto really is Auto. There is no universal bullet when it comes to memory controller voltages, we have to pick a range that works with almost all setups. Too low and users complain some kits won't POST and then expect some kind of workaround. In the end it is down to the user to tweak the system down to lowest voltages - and this will vary from CPU to CPU and according to the memory modules used.Quote:

Sorry if this question has been already answered, but how can I downgrade the UEFI ???
Anybody know if this board will fit into my Silverstone Raven RV02.
Thanks.:up:
it should.Quote:

EDIT: here's a pic of it up and running in the Kublai 04. keep in mind it's far from done;) needs a water loop and much better cable management, among other things.
but the point of showing you this is to show it fits, and still has almost a full inch of room until the board would cover the cable management pass-throughs.

Great many thanks :)
What about on the Rampage 4 Formula? They don't have any of those connectors, so does that mean that I shouldn't push the board? I haven't started overclocking yet, but reading this doesn't sound very good. What OC should I be looking at for 24/7 use? 4.5Ghz? Going to try to set it up with offset at 4.5Ghz like my Asus Z68 MB. Anyone got a link to an offset OC guide for X79 or is it similar to Z68?Quote:

The spec for 8-pin EPS is 4 * 12V + 4 * ground 18 AWG line. Conservatively it can safely handle 28A or 336W and probably 1.5 times that without bursting into flames. I don't think you have to worry, unless your 24/7 clock for 6 cores is 1.6V @ 5Ghz :)Quote:

I've read it overclocks just as well, but I don't see how it can without the extra power connectors that the Rampage Extreme has. That's OK though because I didn't really buy the board for that. I bought it more for the 4 x PCIe x16 slots, in other words for gaming, and I'd say that is what this board is catered towards. Maybe I am wrong though and it can hold it's own Vs the Rampage Extreme.Quote:

EDIT: I have to back what Deachus said. Just push your system. You'll start experiencing odd problems when(more like IF) power related issues pop up. And hey, if the board fries, the ROG RMA department is great about replacing your board regardless of reason of failure. These boards are designed for overclocking and Asus fully expects us to do so.
Anybody have an idea what good settings for BCLK and PCIE skew are for a 3820? In the RIVE OC Guide Raja posted, it mentions the ideal settings for the 6c procs are -2 BCLK and -20 PCIE, but haven't seen anyone say anything about the 3820. I've tried -1 BCLK with -10 PCIE and -2 BCLK with -20 PCIE, but neither helped much. -1/-10 was able to run longer before BSOD, but still very unstable.
If needed, I can post a quick rundown of settings and voltages.
EDIT:nvm, found a post by Sham on another forum(think it was the ROG forum...) saying to try BCLK skews from -2 to +2 and PCIE skews of -20, -10, +10, +20, +30. I'll fiddle with them later and report back.
nice cpu .Quote:

(I started out using medium CPU LLC with a 3960X, but stability was unpredictable over 4.6 GHz. I could perform a 20+ Linx run, then a minute later the system would randomly BSOD or error out 3-4 minutes into another Linx test. Also, try the latest Prime95 with AVX. With these CPUs it seems to cause a BSOD or show errors more consistently and faster when something isn't quite right. Stabilizing the CPU voltage with High LLC solved that problem for me.)
The system is stable at 4.7, 120.6 x 39, 1.35Vcc. Trying to go higher and potentially stabilize 5.0, as temps and voltages are still well within the safe range, but it's being difficult. It could also be that I haven't really had time to sit down and tinker for a few hours continuously.Quote:

I've been using AVX Linpack as it seems to cause higher temps, should I be using AVX Prime as well?Quote:
