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

[UsAs]

Nice result and good temps. When i'm on water, ill see what my xeon is willing to prime.

 

[phill]

Nearly close to 5ghz. i7 3960x @ 4.8ghz with decent voltage and temps with Corsair h100i V2 aio and rampage iv formula..

I'd have to push the BCLK over the 100Mhz mark to get it over the 4800Mhz OCD is a pain lol

I'm pretty sure that adding an NVMe card to my machine has made my machine far more touchy when it comes to altering the bclk from 100Mhz. The P9X79 Deluxe is a great board, but getting it to handle a high overclock is a little tricky. There are so many knobs and levers you can twist and pull that it makes tuning the board an event.

I'm amazed that my 7+ year old X79 platform still can breathe a bit of fire. I originally built it after Black Friday 2012 with an Asus X79 Sabertooth and 3930K. I'll have to do some digging for the CPUZ benchmark but I got it up to 5.02GHZ stable and held the highest CPU score for a 3930K I ever saw on Passmark, around 17,300. After a few years I turned it down to 4.8GHZ then finally 4.5GHZ due to the effects of core degradation. Then I lucked into a 4960X as part of an amazingly cheap package deal on Craigslist for the leftover parts from a flagship Falcon gaming rig that went poof when a coolant line let go. As luck would have it only the mobo died; the CPU, RAM and power supply were still fully functional. The RAM alone was worth more than twice of what I paid for everything at the time.

I swapped the 3930K with the 4960X, set it for 4.7GHZ on all cores with all other settings left on auto. I was extremely pleased that it booted the first time with no issues. That was three years ago and it's still running fine at that speed but now I want to try an E5 1680 V2 in it to gain the two extra cores. I can get the Xeon cheaply enough that if it works as well or better than the 4960X I can sell the 4960X at a rather decent profit margin. Has anybody here done a 1680 V2 in a X79 Sabertooth? If so, how well has it performed? I know there are several posts in this thread but I don't have time to read through all of them. I did see a modded BIOS that adds the microcode updates along with NVMe support. IS there a BIOS that enables everything in the 1680 V2 plus adds NVMe support without the microcode updates? I use that PC for A/V production work and it's rarely online other than to update software. Any advice and help will be greatly appreciated.

@bobbybluz I own 1680 v2 with X79 Sabertooth for about a year now
In my case, OC'ing is mostly limited by cooling (air).
Overall, I got nice speed bump vs. 4960X when program uses more cores (Rendering videos), BUT is slower in Single thread stuff (because my 4960X was OC'ed to 4,5GHz). I CAN force 1680 v2 to run at 4,5GHz, but temps are simply too high.
At this point I'm running it at 4,2GHz and 32GB (4x8GB) DDR3 memory @ 2133MHz CL9 (I will switch MBs when I get to it [already bought better one], earlier I ran it at 4,3GHz with 8x2GB RAM without issues) :

I'm using moded beta BIOS : NVMe support, bifurcation support, all uCode updates and most module updates (iRST/RSTe/LAN and Marvell OpROMs). Download link : LINK. Topic : LINK.

Hey @agent_x007 I recently get myself Asus Sabertooth X79 and I also changed bios immediately with that moded beta 4801 ver. of yours and I follow your instructions from HERE,everything is working perfectly fine(THX) but I want to change the CPU that comes together with this mobo(I7-3820)as I am short on money I want the best price to performance CPU that I can find...Gaming and Editing are priority but also every day normal use....

I wish I can afford 1680 V2 or 2697 V2 but at this moment I can't so this is the list of CPU that have reasonable price and I can get them here in my Country:Xeon 2650 V2,Xeon 2680,Xeon 2687W,Xeon 2658 V2,4930K,Xeon 1650,3930k......more or less all of this CPU's prices are somewhere in between 40€-100€ and that fit's into my budget plan,so PLS. do you have any experience with any of those CPU's and what is the BEST CPU from this list in your opinion....

P.S.Is there any benefit from V2 CPU's or I7's that are build in 22nm technology compared to the 32nm....I assume less power and heat?

 

[UsAs]

Get yourself a 1650 (SandyBridge) or 1650V2 (IvyBridge). I got an V2 which overclocks well. Sandy Bridge has less temperature and is 5 to 10 percent quicker at same speed due to more modern architecture.
And before you want to buy an 1680V2 think about getting a Ryzen system. A 1680V2 is still very expensive these days.

I run a 2695v2 on a Sabretooth board.
Does that modded bios solve the issue of a loud pch fan?

 

[agent_x007]

@Lorec Not sure what you mean by loud PCH fan ?
Doesn't Hardware Monitoring options for PCH fan speed work for you ?
You can also change fan profile in ASUS AI Suite (under "Radar").

@Zyll Goliath 22nm CPUs don't need "NV fix" for PCI-e to work at 3.0 speed.
Less power/heat is only up to ~1,35V, 22nm FinFET doesn't like high voltage (it heats up REALLY fast after this point).
PS. I updated my original post of that topic just now for additional moded BIOSes

THX for the advice...also I didn't know about that"NV fix"...hmm...so all in all then 4930k or maybe 2650 V2(that is really cheap here) are good solution in your opinion?

 

[UsAs]

2650 is locked. You aren’t able to oc. Only a few mhz with bclk which isn’t recommended.
The 4930k is unlocked. Better one.

Yeah I know that...but also have 8c/16t and its much cheaper....seeing some people did fairly good BCLK OC with that cpu....

 

[agent_x007]

To get good BCLK OC on that locked Xeons, you need to modify BIOS (otherwise you are stuck at 100MHz strap), and even after mod - it's not guaranteed to work in every case.
I would focus on how much your programs will scale with additional cores vs. 30% higher clock speed.

 

[UsAs]

Depends on what are you‘re going to do with the system. For rendering the more cores the better.
For gaming you should take a unlocked one for high per core speed.

Hey how's that CPU doing in gaming and did you menage to do BCLK OC?

 

[HUSKIE]

Don't buy 2680 Xeon Cpu for x79 MOBO, I had one on here can't overclock at Xeon thread pages 189

 

[bobbybluz]

Thanks for the informative responses. In my case cooling isn't an issue. I'm using a Corsair H105 w/4 Silverstone FM121's in push-pull running at full speed (110cfm each) plus the radiator is mounted externally on top of the Corsair C70 case for more internal space. That proved to be extremely helpful when I added a XFX R9 Fury X I got cheap earlier this year. I ended up mounting the radiator and fan for that externally as well. I'm using a Corsair C70 case and it has two Silverstone FHP141's running at full speed (173cfm each) in the side window. Airflow isn't an issue at all, I have 20+ years of experience modding cases. It sounds like a small vacuum cleaner but so do the rest of my rigs.

The pictures below are from 4 years ago when I did a major teardown and cleaning of the X79 rig. Since then all of the hard drives have been replaced with the main system drive now a Samsung 860 Evo 1TB. When NVMe support is added after the new modded BIOS and 1680 V2 are installed I plan on using a Samsung 970 Evo Plus 1TB for C:. The 64GB of G.Skill 1866 Z-series has been replaced with 64GB of Corsair Dominator 2133 and the XFX R9 290X got swapped for a XFX R9 Fury X. As I previously mentioned the 3930K was replaced with a 4960X a few years back. I think I also changed the PSU when I did the CPU but I can't recall at the moment (having 6 high-end A/V production desktops makes it difficult at times to remember what's residing inside some of them). I'll post a pic after the next upgrade mission.

Back to the main point: We all know that the overclocking lottery varies with each individual CPU. I may strike gold again with the 1680 V2 or end up with fool's gold. It's the chance all of us take in this game. Winning adds to the adventure, losing means putting it up on Ebay and hoping the next one is better. Even though I'm officially retired from the IT and computer building/repair business (over 1,000 builds in the past 20+ years) the passion still exists and milking that last drop of goodness is something nobody but folks like those here understand. It appears to be a great crew here and I'm happy I finally joined after many years of lurking.

One E5 1680 V2 is on its way to me. The addiction continues...

 

[Lorec]

Hey how's that CPU doing in gaming and did you menage to do BCLK OC?

I mainly 24/7 crunch with it.
I used it as a temporary pc though for a bit and well the most important was to change the default option in bios to sync all cores sitting @2.4ghz
on Auto one core can boost till 3.0 which is something.
I also disabled spread spectrum.

 

[Zyll Goliat]

Ok guys at the end I get that Xeon 2650 V2 and so far I didn't regret...it was really cheap(40€) and I menage to OC via BCLK(112) so it's working on all cores 3,360Ghz and turbo all the way up 3,8Ghz on 1-2 cores...
Here are some bench results:

I still didn't game a lot...I will do more test in following days.....

 

[bobbybluz]

It works! Next comes the modded BIOS and a NVMe system drive.

Now I need another X79 mobo for my homeless 4960X. Looking for another X79 Sabertooth or an ASRock X79 Extreme6. The prices sure have skyrocket recently!

 

[bobbybluz]

Here's the CPU-Z verification for my old 3930K from 7 years ago. 5.022.57 MHz. Now that same mobo has the E5 1680 V2 in it. https://valid.x86.fr/show_oc.php?id=2616338

 

[FreedomEclipse]

Good voltage for 5ghz

 

[Zyll Goliat]

Guys I wonder did any of you tested&benchmarked X79 platform with spectre&meltdown protection ON/OFF and did you notice any significant difference lately?

Nah, I just Linux with the kernel options

mitigations=off

It's not a shared machine and people don't have access to VMs I run on it, so I'm not worried about it.

As far as Linux is concerned, there have been benchmarks for how much of a toll the mitigations take on newer hardware, I can't imagine it's any better with older hardware.

I like Linux and I will migrate tomorrow totally to that system IF gaming is not the issue.....tho' now I also have some very old nokia booklet 3g that I installed Linux(Knoppix)on it,how HDD is broken there I picked a system that can work from usb stick and that was Knoppix(based on Debian)and you know what it's just works as intended even machine is old&weak and whole system is on usb stick I can surf the net and play some games on emulator......
