X79 and/or rampage IV OC'ing thread for those of us still left....

Looks like I got most of my bandwidth back to stepping ram to 1.35, and 2600mhz:

You could try to play around secondary or tetriary timings to get some more out of them (but I'm not sure how good your chips are though, so it may not be worth it).

^This is fully stable with 1.48V on DRAM in BIOS


I'm using four single rank B-die DIMMs (B-die = DDR3 timings, on DDR4 clock speeds).

 

[ThrashZone]

Hi,
Pushing the cache higher will lower latency a bit to.
Watch or limit the vccio & sa voltage to system default which is I believe 1.05v otherwise auto will be extremely high so max it 1.1v otherwise might toast your chip

Because of this, I got board with measure point to manually check what it does when I set offset on VCCSA (along with OC Socket switch).
I got "fixed" option for voltage on VCCIO, so that's fine.

Hi,
Broadwell-e bios updates really screw haswell-e up voltage wise pretty much why I use old bios
Just activating xmp profile throws auto voltages insanely high.

At hospital waiting atm for port to be put in for fiancé but will be interesting to see how my recently acquired b die's do on Z69 vs your X99... When and if I get near my pc again lol.

Glad others are posting and doing stuff... I'm kinda drained emotionally and living vicariously through what you guys post

Hope she get's better :/

As for tech : You will "reck" my latency number pretty easily (even in other latency based benchmarks that AIDA64), BUT you can forget about getting my bandwidth numbers. 256-bit bit bus FTW


^Latest for now

Here's what I set in more reasonable program along side 1h of memtest5 (custom settings) :

They are pretty useless for everyone else using B-die though (simply because they are validated for just 3GHz effective clock).

 

[johnspack]

Man... 30% more bw than I got.... I'd kill for your ram! I got my ram to 2666 and got a slight increase. Then I got my ram to 2800... and my bw tanked. Same timings too.
Ocing ram is weird stuff. Either my imc can't deal with the speed or the ram can't. Wish I had faster ram to test that theory out. Oh well. The 5820k is
at 4.6 now, at 1.275v, but will do 4.8 easily, and maybe more as I didn't test. My low end aio can't quite cut it above 4.6.

I doubt my 12900k will do better for latency #’s, you have 46 ms and actually the bandwidth #’s are what I am hoping to get close to. Aiming for ~ 80k the latency I think will be more like in the 50’s I think…

 

[agent_x007]

Man... 30% more bw than I got.... I'd kill for your ram!

Actually, it's really not THAT expensive, I'm using this (just two kits for 32GB) :

Not that expensive at all actually…is that b die? Also what is the standard voltage for 4000 mhz @ Cas 16?

 

[agent_x007]

@dalekdukesboy Yes, as mentioned previously, they are B-Die. 1.45V for 4GHz CL16.16.16 (ie. "flat 16").
Buildzoid take :

Just FYI : XMP profiles for those WILL NOT work on X99, because frequency is too high on 99% of CPUs (even 3600MHz second profile).
You can use timings from profile as base (put in manually) + lower frequency to what CPU can take to boot, and tune stuff from there.
Also, if I wanted to get new dual rank B-die kit (so, the same capacity 32GB, but in two DIMMs), I'd have to pay 60% over the price for two of these Viper kits. In math language : DR B-Die (2x 16GB) = 1.6 x 2x SR B-Die (2x 8GB), or NUTZ pricing level

Hi,
I just got a set of trident z royals 4000c16 2x16gb 16-16-16-36 and xmp voltage is 1.4v
My 3600c16 4x8gb kit same tight timings needed 1.45v to do 4000c16

Sorry you did say it was b die and the ddr3 like timings etc... Just tired and mind is mush life is bit upside down lol. The stuff I just bought is CAS 17 4000 mhz but only 1.35 volts so probably be very similar as I add voltage and tighten the settings.

Trident is bit better but both are actually pretty good.

 

[johnspack]

Dam, it's partly timings as well... I couldn't go above 2666 and get higher bandwidth, so next I went for timings. Started with 15-15-15-38, so I went with 14-14-14-32... up went the bw!
I'm pumping 1.35v into these 1.2v rated modules, so they should jump a little heh...: I've got to try for 70 at least... not dam bad for 1st gen cheap ddr4 modules...

Some day the Canadian gov will give people on pwd enough to live on, but for now we get like 200-300 after rent and utilities to live on. 350... after conversion and customs
is still way too much for me. Guess I'll stick with the old school ram for now!

 

[johnspack]

This 5820k is bonkers.... it doesn't seem to have any walls... brought my ring bus up to 4.4ghz, and yet more ram bw.... I wanted close to 70 and I got it:

Never mind... bonkers... as I now call it is doing 4.6ghz ring, and I'm passing 70 now... if I get a better cooler, I'll hit 80... swear to god!

Boooo! Bonkers will only do 4.5 ring bus stable after a bunch of testing. I did read online several places that said that 4.5 is max. Now I believe them.....

You should try a different strap with none matching bclk. or try the 100 strap at least with bclck below 100. X99 suffers the same bugs with higher ram dividers like X79 does.
I can tell by your lower readspead in comparison to your write and copy that you suffer from this.

I agree with everything BZ says in this video besides flat 19s @ 4000MT/s is Samsung B-die.

He talks about Crucial running +4000 @ RCD 19 later in the Video.

@buildzoid Have you seen Micron 16GB Rev B SR doing 3200-14-14-14? I believe you may have this RAM Kit in the kits Crucial sent to you.
Subs timings were left on Auto I know you don't like that.

My uncle underwent chemotherapy for throat cancer 2 years ago and the cancer was defeated. He was a heavy smoker and still smokes heavily.

My quest for 32GB DDR3 2400 RAM is finished. As you know, I already owned 100% stable Corsair Vengeance 16GB RAM. I snatched another 16GB Vengeance RAM with the same PCB version from eBay, but the sticks are gray. My 32GB RAM is a mix of red and gray sticks.
Below is AIDA screenshot with 100BCLK. You can guess that write speeds are lower due to the CPU strap bug.

BCLK adjustments did not help. I then tried 125 strap. The RAM ran at 2333 MHz, but write speeds increased nonetheless.


agent_x007 must be very lucky to be running overclocked i7-6950X at 4.4GHz on air cooling. I also have i7-6950X and it can pass Cinebench R15 at 4.3 GHz at 1.24 Vcore. But the chip reaches 80°C on 280mm Corsair H110i GT. It can boot Windows at 4.4GHz, but as soon as I run CB, the screen goes black and the PC shuts down most likely due to overheating. My chip must need custom water loop with triple radiators.

I also have 18-core Xeon E5-2699V3. V3 Xeons are fun, because with the custom UEFI and undervolting, you can run them at almost max turbo frequency. I found out after purchasing my E5-2699V3 that the best V3 Xeon to get is actually E5-2696V3 because it has 38x max Turbo multi instead of 36x multi of E5-2699V3.

My E5-2699V3 was running at 2.7 GHz at stock with the original BIOS on ASUS X99-A.

After BIOS mod, I tried to undervolt -0.125V, but Windows did not boot and blue screened. The highest frequency I could get was 3400 MHz with -0.1V undervolt.


If you increase the BCLK slightly, the max multi is also increased under load. The max stable BCLK on my motherboard is 103 MHz. The max multi I achieved was 35x with -0.08V undervolt, which equals to 3600 MHz frequency.


I tested the stability with Prime95 Blend and -0.1V undervolt was not completely stable. -0.06V undervolt seems to be stable on 100 MHz BCLK, but on 103 BCLK causes WHEA Corrected Hardware Error in Event Viewer. My chip is completely stable with -0.05V undervolt on 103 MHz BCLK and the max sustained multi is 34x. Of course, other people may have better luck with the silicon lottery and their chips can be 100% stable with -0.095V undervolt as recommended in Tech Yes City video.

Hi,
I wouldn't count aida64 as any type of stability test
It's mainly just a memory latency test
Even it's stress test is pretty lame sadly.

You can try blender opendata
Blender Open Data — blender.org
Or a quicky is good old R23 loop.

I only run at 4.4GHz for short (no AVX) tests, also - I can't really do it in summer.
Usually, I keep it at 4.26GHz @ 1.28V. It's really not that great of a sample (but does 3650MHz on UnCore which I prefer over 40MHz in core clock).

Hey, maybe you can provide some single core bench numbers please (all cb versions, geekbench, cpu-z and whatever else you got? Would be very nice since i am exactly thinking about doing this litte upgrade.
I have a rampage v laying around with a 14core e5 v4 (sadly 2 memchannels are broken due to damaged pads), an e5 1660v3 8core (i see not that much of a gain to switch from my 1680v2) and was thinking about giving the turbo hack a try with the 2699v3 or the 2696v3 (as you stated the better option, but harder to find) and i want to know how much single core performance i will lose.
The 6950x is still too pricy in the used market.
Just want to know if it is worse the hassle to get all watercooled and teardown my watercooled x79 build.
Thanks

The CPU was running 31x multi during CPU-Z benchmark.


Windows Task Manager showed that the CPU frequency was jumping between 2.8GHz-3.0Ghz during the Cinebench runs.



There are plenty of E5-2696V3 CPUs available on Ebay. This is the cheapest listing: https://www.ebay.com/itm/284905292850

If you get the silicon lottery winner chip that can take too much undervolt and your motherboard can take 105 BCLK, then theoretically you can run E5-2696V3 at 38x105=3990 MHz. That's 18-core 4.0 GHz for you! However, these CPUs don't require exotic water cooling. 240mm AIO is sufficient to keep the temps under 75°C even when running Prime95.

I checked prices out of curiosity the 6950x can be had for 200-280 US.

If gaming is not the primary usage of his X99 system, then 18-core Xeon would be better option due to being cheaper and faster in multi-threaded workloads.
