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

[agent_x007]

XMP profile made for Haswell, won't work on X79.

Oh, that's disappointing. But hopefully it will overclock better than other more standard ram.

 

[agent_x007]

You can put everything manually though.
Critical stuff is tRFC and first four timings with Command Rate.
Unless you have... problematic RAMfor your MB, which may require manual secondary timing tweaks.
For 2400MHz, you may need a bit more volts on VCCSA.

 

[X79User]

Is there a good ram oc guide for x79 you could link me to? Is there a stock set of values (for those timings) i could try for 1866, 2133 or 2400 mhz?

 

[agent_x007]

Nope. You can check what SPD/JEDEC/XMP profile says (in CPU-z for example), and go from there.
I managed 2133MHz on my memory.

I'd recommend skipping all 2011 at this point sub 1680v2. They're so cheap now, you can get amazing performance for like $150, slays all Zen, Zen+, and most 2011-3 chips for gaming and productivity.

One of the most underrated CPUs of all time. 55%+ OC very easily from 3.0 base to 4.6-4.7 GHz on 1.35 volts.

Memory controllers strong usually too, mine was happy at 9-10-10-9 1t 2400 with64gb

For memory OC guide, search for rampage 4 black OC guide on ROG forums. Lots of good ram info there.

So much as I love your comments I have to ask the obvious, why do you have a 3900x now? I admit, part of me due to being in a good situation atm is thinking of building a crazy 3900x system but power draw alone would be scary I'd think.

So do you run the 1680 v2 Ivy-E or the 3900X in your profile system specs?

Why not X99/1680 v3? Wouldn't it show a noticeable boost in performance over the 1680 v2?

Just noticed this was last reply in here and I knew not much had been going on since I had no notifications coming in but just wanted to "bump" the thread and 4's comments here, I also was curious about if Othnark had only the 3900x system listed in his bio or if he did still indeed have the 1680 v2 system he referenced having. It sounds like he was quite happy with it and obviously is recommending it now as a viable option over 2011-3 chips and some Zen's.

Hey all, not done much with my system but I did do a couple runs and was curious on what was causing the multiplier downclock and I'll have to post it but it's a very useful reply I found in a thread. Basically, the VRM's overheating automatically causes the CPU to clock way down with an instant drop in multiplier, and it so happens the thread I found was about X79 so the CPU even clocked down to the identical 1400 mhz mine clocks down to! I used to have more fans than I probably needed but one fan I did away with thinking the RIVE black improved the heatsink enough was the fan right over the VRM's but at least under enough stress and an OC it obviously can't handle it. So I'll be tie-wrapping a fan or so me such mod over the VRM heatsink. I could take mobo out and reseat the heatsink but doubt I'd improve it enough to bother with...not sure you can use TIM under heatsinks very effectively vs. the tape they use.

Since half of the vrm heat output is at the back of the board this is not much of a surpise , hopefully you are able to get your front so cold with the attached fan that the back is getting cold enough too. This is why i watercooled my RE IV F. VRM stock heatsink design of i think all x79 boards (at least with asus ) is some kind of arkward since half of the nfets are at the back.

Last week i found some time to optimize the voltage and settings, right now i am sitting at 4,4ghz with 1.208v under "normal" load (like CB15) and 1.216 to 1.224v under heavier AVX load like LinX or y-chruncher. C-states enabled and limited to c2.

4.5 looks to be able with round about 1.28v but i think the voltage bump is not worth it since i use this as daily driver. Next thing is some ram tightening, sadly my 32 gbcorsair dominator platiniums are rated c11 2400 and i can not get them to cl9 at 2133.

Something that me really make a little bit sad about this plattform is that you can not use the 2400 ram multiplier with 100/100 due the known bug and that you can not use power saving (idle voltage) features with 125 or higher strap. I would love to have 2400+ running with it (i have some 2800 plats but only 16GBs that runs without problems) and powersaving but this is not going to be.
Really sad, even with my 4.6ghz X58 setup i was able to run 2400ish ram and with at least c1e states that drops idle voltage.

But i am ok with the current setup and performance, pushing it more will be something in the future for my benchtable ;D

@drizzler Check what manually inputing tRFC from XMP profile and setting 0,95V on VCCSA does.

Thanks for the post and the info, I did wonder about the back of the board because I did notice since I have both sides off of my case just due to laziness and ease of access that the back of the board the few times I went back there just to check it out can be pretty damn hot...I have a Silverstone case which has a cutout in the back so I did consider throwing a fan back there somehow wondering if it'd be worth it...obviously by what you're saying the answer would be yes, on top of freezing the front as much as possible as you said as well.

That's a nice overclock voltage for 4.4 ghz, I'm currently sitting at 4.5 simply due to the throttling problem I found and it may only show up on Linx when I'm stressing it far beyond any app I use but I'm going to play around with my fan placement and would be pretty neat to see the throttling go away if it works, rarely do you do something so simple and it makes such a big difference, often you do stuff that seems good in theory but in practical reality when put into practice they accomplish diddly squat.

So you said your formula board you WC what cooling do you have on your current board and it looks like a Rampage in your attachment is it regular rampage or the black version? Great post!

 

[drizzler]

It is a Formula ;D

Guys I'd like a penny for your thoughts...

I'm trying to put together a PC for a friend who's not well and basically has kidney problems..

So I'm thinking, X79, 32GB some sort of Xeon(??) possibly a 8 or 10 core if I can find one at a daft low price and then whatever else I have laying about here.. I've got a 1080 Ti with water block, so I was toying with the idea of that and water cooling the CPU as well for him, never had water cooling and hasn't even had USB 3 yet, so..... What sort of CPU might you guys suggest?? Been looking at the following few Xeon's that seemed to be a fairly decent option....

Xeon E5 2658 V2 10C 20T 95w
Xeon E5-2660 v2 10C 20T 95w
Xeon E5-2650 v2 8C 16T 95w

I tink I'm more tempted to get a slightly slower 10C than a slightly faster 8C.... But what do you guys think??

Maybe I'm misremembering but I thought you already had an 8 core or something in your X79 system?

 

[phill]

I believe I do, but as I've a few X79 boards and it's for my best mate, I figure I could try and see if there was a faster 8 or 10 core out there that might have been better again to use I think now you've reminded me, it was a 2.00GHz CPU... I'd like to give him something a little faster if I'm honest

 

[dalekdukesboy]

Well all, I had a new version of windows download last night along with some updates, my windows was shaky as it were with some issues, I hoped this would "fix" my problems. Yeah worked great all day, restarted my pc and windows splash screen just crawled with little circles windows has going in circles as you start up....barely moving. Basically all but frozen and never would restart I'm sure and I wasn't leaving it on hours to find out. I just reinstalled windows 10 from the USB I bought it on and thankfully I had it handy to just plug in and within 45 minutes I'm back up and running again...however now I have to see what is in my windows.old file (like everything) and try to get it working in my fresh windows install which is essentially empty of any apps/programs/games etc. What a PITA! Oh well. Not sure how well or easy it will be getting all my files restored but to at least get back online wasn't too hard. The ssd admittedly installed windows way faster than last time I did it on my 10k raptor drive.

Ah yes unless he can OC it well 2.00 ghz particularly on this older platform is somewhat archaic and slow....I'd recommend the 1680v2 because they clock like mad and are Xeon tough silicon and you get 8 cores and a generally very good memory controller to boot

Speaking of, my windows still needs a few updates and I'm not particularly good figuring out the windows.old folder and how it works despite all the things I've read now about it. Restoring pictures and files like that is pretty easy but trying to find and put game files back where they belong in steam etc....not so easy. There is an auto restore tool but ran into a snag with it not sure the deal....However I'm pleased to announce I lowered voltage significantly and got 4.5 ghz stable with no throttling! However VRM heatsinks were quite hot after 6 runs which is why I stopped it, so
original plan of putting serious fanery on them will have to go forward.

Low voltages and low temps for 4.5 ghz. Not even sure that much voltage is required or not I just picked a lower voltage than I have tried in past and gave it a try.

 

[bobbybluz]

That looks good. The lowest I've had the voltage on my #2 1680 V2 is 1.3 at 4.6 volts. I've been so busy I haven't had time to play with it other than to do updates last week but my #1 1680 V2 is in use nearly every day for audio production.

Found the CPU I had in the boards, a 3820, E5-2650 V2 I think and a 4930k... I've managed to grab him a 10C 20T Xeon and I've managed to grab a PSU for it as well, I'll put some pictures up when I'm done with it.. I'm not so happy with the tubing and I think I'm going to have to swap out some of the fittings for others ... Which will be a blood night mare but.... lol He won't need the raw clock speed rest ....I'll see how this one goes and if needs be, I can always put the 3820 in there instead...

 

[bobbybluz]

Has anybody tried a 22 core E5-2699 V4? Asus claims one will work in a Sabertooth X79. I know where one is locally in a decommissioned server but the price for the whole unit (won't sell just the CPU) is more than I want to spend at the moment.

I'm too busy to be playing with this, I just said to hell with things and did it anyway. Now I just have to get all my stupid steam games working...I hate how they arrange folders etc it's a maze of mess just waiting to fail...

That's for 2011-3 so unless you can perform some kind of magic there's no way that CPU should work.

It appears reinstalling windows fresh on SDD vs. cloning an already abused copy was a good idea. Everything is more stable and overclocks with FSB suddenly are working again, for a while I gave up and thought maybe it was a cpu/platform thing and it appears it was a WIndows being half broken limping sort of thing...also using far less voltage than I recall for all of this, again I just picked the voltage I haven't even tried for lower yet!
