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

[lexluthermiester]

It seems that I was lucky and got a good CPU ... it only needs 1.256 mv for 4,4ghz
The max temperature was 51 C while running Aida64 Stresstest for about one hour (thanks to my water loop)

That is CPU silicon lottery in your favor! Nice!

Hi all, back from dead.
Had a lot of stuff on my head until recently. Also will be moving in a month but finally found some time for testing.
While I could have played again with 1680v2 I felt a little rusty so decided to have a warmup and got myself 2697v2.
Actually I was surprised how easy it was to overclock and how stable it was afterwards.

Ended at 114bclk with llc at medium and vcore offset of +0,08. Had to step down one multiplier on ram because even when it was working without changing voltages, system seemed sluggish (old 1600mhz set so didn't expect much).

All core turbo 3420mhz
On paper max one core turbo of close to 4Ghz but best what I have detected was 3,9Ghz.

Stress testing with occt, lynx, aida64, prime95. Everything stable and max core temp 54C.

Although found it weird that anything over 114bclk was instantly black screen. Even 114.125 was not booting no matter what offset I choose. Maybe it's the limit for this mb.

After tweaking and testing I found the sweet spot of my 1680v2. It seems that I was lucky and got a good CPU ... it only needs 1.256 mv for 4,4ghz
The max temperature was 51 C while running Aida64 Stresstest for about one hour (thanks to my water loop)


All in all I´m pretty happy with that "old" CPU. In the next days I´ll try to find it´s max stable clock. But 4.4 with 1.256 mv will be my 24/7 setup anyway ...

Keep going testing and optimizing. Maybe your cpu is capable of more with less voltage.
I was starting at round about the same amount of voltage for 4.4ghz in the past but i was able to reach 4.6ghz with only 1.26v under load (see some earlierer posts) by testing out cpu_pll , skews and vrm setttings. Finding a well working cpu_pll is crucial, i can even use something like 1.3v with my cpu and see some small gains in performance but sadly my usb audiobox is dropping out with too low cpu_pll (this may need some adjustments of pch voltages) but 1.6 is working well too without issues with 125 strap 122blck.

Right now i am sitting at 4,5ghz / 2600 ram with 1.216v load and 1.23v idle (different strap and different memory compared to the 4.6 setup) for 24 / 7. Greetings from germany ;D

@Duc996 As much as I'd like to agree with drizzler, a word of caution: If this is your daily driver and that OC is solid stable, call it good and be happy with the massive OC you're getting. However, if that system is just a tinkering machine, push it to see what you can get and have fun!

 

[Duc996]

@drizzler Your results are great and made me curious what my CPU is capable. I´m not sure if my MB can handle those pll tweaks. I recognized voltage drops under load ... my voltage is just stable without heavy CPU load. The more load the more drops. I need to try 125 strap anyway.

@lexluthermiester It´s currently my main rig. I´m fine with the performance at the moment. On the other hand I´m a collector in some way ... I have four watercooled Asus Rampage based PC´s and I switch from time to time. At the moment I´m sitting next to my Rampage Formula running a Q9550 ... that way it´s more or less a tinkering machine.

Guys I have a question.....did anyone managed to turn on PCIe Resizable BAR on X79 platform?

 

[lexluthermiester]

Guys I have a question.....did anyone managed to turn on PCIe Resizable BAR on X79 platform?

Is it possible?

 

[Zyll Goliat]

Well...If I could guess I say theoretically it is possible...I mean on X79 we can turn on Above 4g decoding in bios the thing is that someone we the little knowledge could possibly moderate the bios and solve this problem in the future.......BTW Also some people claim that resizable bar working on older card without the problems even if the GPU are not supported....here bellow pic with the R9 390....

They claim that actually unsupported GPU is not the issue if your motherboard/bios allowing that resizable bar could be turned on....

Fair enough. My guess is that a BIOS hack would be needed.

 

[Toothless]

I forgot if I asked this in this thread, probably did.

Anyone try the 1680v2 in a x79 Classified? I'm about to pull the trigger on nabbing one but I want to make sure it'll work. It's not on the official support list on the EVGA site.

As long as your BIOS is upto date, you'll be good.

 

[Meese]

Hello everyone, been interesting reading though this thread, gave me the idea to go and buy a e5-1680v2, got it for £140, received it today but haven't installed it yet. Hopefully it's a lucky chip with good oc potential and will tie me over for a couple years till ddr5 and pice 5.0 are out and see what amd or intel have to offer in 2022/23
It's going to replace my i7-3820 on a rampage iv extreme, been going strong since 2012 running at a stable 4.2 since then (1.29 vcore, 36c idle 68c at 100% load, 100blk, 42 multipler), computer rarely gets turned off manged to get 4.6 but don't use it at that for daily use could probably push it higher, seems to be a good chip. Using a Coolermaster master maker 8 air cooler atm, replaced a h80 after the pumped failed after 6 years.

Anyway I need some help, I'm super indecisive, currently using 16gb corsair vengeance lp 1600mhz c7 memory(4x4), overclocked it to 2133 c8-9-9-26 and has passed all stress tests, get a higher score in aida64 slighty(50231 read, 58562 write, 51987 copy, 51.9 latency) but about 1000points lower in realbench compared to leaving it in xmp at 1600 c7.

My question is do I buy some different ram and will I see much benefit from a higher mhz, from my understanding there's a bug at 2400 or is there a work around? is 2600 doable and stable on the 1680v2?
Currently can find some 32gb 4x8 kingston hyper x savage 2400mhz c11 for £160, it's low profile so in slot 2 and 3 on the mb it will just fit under my cooler as its quite big and just hangs over these slots but from reviews you can't oc it at all over 2400 or I get some Avexir Blitz 4x8 32gb 2400mhz c10 which is easily overclockable to 2600 or even 2933 but would require me to change my cooler to a aio like the ek 240 or h100i. Can't find any 4x4 or 4x8 matched sticks of G.skill Trident X or other good ram really.
Should I just stick to my current ram or upgrade, what do you think?

Once I fit the e5-1680v2 and ticker with it and see what oc I can get I will let you all now, hoping to just get 4.4 maybe 4.5 with low vcore and decent temps for daily use, any advice on bios setting to achieve this?

Sorry for the long ass post, appreciate any help or advice

 

[lexluthermiester]

It's going to replace my i7-3820 on a rampage iv extreme

Going from a i7-3820 to a Xeon 1680v2? That's an upgrade you will feel the performance impact of! Very solid upgrade. Little tip, before switching the CPU's over, load BIOS defaults for RAM and CPU settings. The 1680v2 has a different IMC and those RAM timings are unlikely to work in a straight swap of CPU. You'll need to retest your RAM and timings as you test for the OC on the 1680v2. Focus on the CPU OC first, the dial your RAM back in. If you can't match what you have now, you'll likely get close. Keep your expectations realistic and you should end up with a solid OC and stability.

My question is do I buy some different ram and will I see much benefit from a higher mhz

With the motherboard you've got, changing RAM will not be of much benefit over what you have now. 1866 DDR3 Standard and ECC is getting pricey. If you had a board that supported Registered ECC, that stuff is cheap. But your board only supports standard and ECC DDR3. If 16GB is getting a little lean for you, try to find a matching 4x4GB 1600 kit and then play with the RAM OC a little.

 

[Meese]

Yeah looking forward to seeing the performance boost over the 3820 and tickering with the 1680, thanks I'll give it a go tomorrow, just waiting for some TG kryonaut to arrive.
Max ram I'm using is between 12-14gb so getting close to 16gb, was trying to find some matching sticks but had no luck, also find I run into problems sometimes when ocing when not using factory matched sticks, reason I was looking at 32gb is because I can't find any good quad channel RAM in 16gb but found a couple in 32gb, so tested my ram recently to see if it would oc any higher than 1866 and was surprised I was able to get 2133 working stable in those timing using 1.6v though, hopefully I'm not putting to much stress on it. Not touched secondary timing as I don't really understand it much.
I'm mainly using this rig for gaming now when I have time, and like messing around with overclocking, will I not see much benefit then running at lets say 2600 compared to 2133 and just save myself some cash, I would just buy them and try it out for fun if it was cheaper

 

[lexluthermiester]

was trying to find some matching sticks but had no luck

When I said "matching" I meant to say specs, such as matching speed, timings and voltage, not the make and model.

For example, your Corsair DDR3 1600 at 7-7-7-20 timings at 1.35volts, then try to find DIMMS with those specs. You might also want to try a set of 2GB DDR3 DIMMS. 4x2GB added to what you already have would give you a total of 24GB and would be set you up for the functional life of that system. This presumes your board has 8 DIMM slots. What board do you have?

BTW, Welcome to TPU!

 

[bobbybluz]

Both of my 1680 V2's do 4.7Ghz easily. I have 64GB of 2133 in one and 64GB of 1866 in the other. Keep them cool and you're good to go. I'm using Arctic Liquid Freezer II 240's with 4 110cfm aftermarket fans in push/pull at full speed in both of them. BLCK is at 103.4 in both of them, had stability issues with higher than that but not a single crash at that speed. Remember that Xeon's are the best of the best silicon. They run cooler with less voltage than any of the i7's plus you get two more cores. I'm not a gamer but for A/V production work they still do a great job. Don't cheap out on the cooling and they should run just about forever.

 

[Meese]

Ahh I got you, yeah it has 8 dim slots, it's a asus rampage iv extreme, so will I not experience much issue mixing the ram with similar spec, tried it in the past with dd2 but kept running into problems so haven't done it since, I'll have a gander on ebay and see what's about but there's not much about in c7. But I should be fine with 16gb I reckon, more curious about seeing what I'll gain with higher frequencies and don't think I'll get much more out of the current ram

And thank you

That's good to know, excited to see what I can push out of it, never oced an xeon before, I'll try at that BLK, see what happens, what motherboard are you using?
Was looking at the arctic coolers, I'm limited to 240mm in my CM haf x case, spotted a ek aio on ebay for a good price might just snap that up and put 4x120 noctua fan on it. Should keep temps nice and low

 

[bobbybluz]

Asus Sabertooth X79's. I have the fans & radiators mounted externally on top of the cases, gives a lot more room inside plus isolates the radiators from internal heat. If noise isn't an issue the Silvetstone FM121/ EverFlow R121225BU is the way to go. Even slightly more extreme are the Delta FFB1212SH's. Around $10 each including shipping from China on Ebay. You'll have to run those off 12 volt Molex connectors with adapters. They push around 140cfm each. The Delta's are the best deal for the price and performance if you don't mind the noise. With a Dremel tool and high speed carbide cutters you can mount radiators where you want them, the same goes for fans as well.

Sorry for the long ass post, appreciate any help or advice

First of all Welcome!!!Now I will suggest you to NOT buy immediately faster ram first install and OC yours 1680 V2 and see how far he can climb up because sometimes on those higher clocks(4,5Ghz+) if you manage to achieve that you maybe not going to be able to run much faster ram speeds....really depends on overall stability of your system and anyway on X79 ain't always that easy to go over 2133Mhz and gains are usually negligible in real life applications....so my advice is go slow step by step and then see IF you really need faster ram that you already have......

 

[Meese]

So I've been tinkering away tonight, manged to get 4.549, 44 ratio, 1.3vcore, BLK 103.4 and RAM at 2206mhz 9-10-10-28with 1.65v(will try and tighten better), set VTT to 1.05 and second VTT to 1.0599, VCCSA to 1.1, rest is on auto, virtualization is turned off, left speed step set to auto, c states on auto and turbo mode enabled, should I disable c state?
Not sure what to set the LLC to or if I should try offset, Vcore is set to 1.30 but any reason why hwmonitor shows about .2 higher to whatever I set it to in the bios? As you can tell I'm a bit of a noob at this

Temps are between 36-41 idle and 78-81 under max load with my air cooler that isn't to bad but could be better so might grab a aio, should drop it by about 5c, found a h100i xt pro for £50

Seems to be stable after a couple stress tests on realbench, got a realbench score of 147,735 and aida64 memory bench score are quite good. Will post some pictures

Tried pushing it to 4.653 but bsod on the stress tests, upped the vcore, vtt and pll but still no joy, maybe lowering the frequency to 1953 will work, will try that tomorrow.

Anything you recommend or think I should try or leave it as it is?

 

[drizzler]

Hey, the "bump" in vcore is LLC related (i guess you use auto so the rampage iv is using very high or extreme seting if i am not mistaken) and switching frequency related.

No LLC : Lets say the cpu is needing 1.3v to receive 1.25v under load , so we have to set 1.3v in bios to have a stable cpu.

Some people tent to say : ok, so i let LLC come into the play and i am able to set 1.25v in the bios because LLC prevents the vdroop (the drop from 1.3 to 1.25 we saw before)

So for example : 1.25vore with LLC Very High is giving you 1.25v all the time from software readings.

But here is the problem :

The boards vrm can not regulate the wanted vcore in a all time constant way, it has always to be adjusted so we always have some kind of over- and undershoot of vcore (especially while load is changing).
How fast your vrm can adjust is directly linked (not only but this is something you can set within your bios) to the switching frequency. This determs how often the "vcore is checked and adjusted" within a second so with a higher frequency we usually have less over-and undershoot but some other negative effects like switching losses for example.

So what can happen with LLC is that your "entry level" of vcore is too low, so that if undershoot is happening the system will crash cause the cpu is not getting the needed vcore anymore.

So from my experience you want to have some vdroop to prevent this and since the cpus are intended to work with this (this is because they should work with all mainboards as well as they could, so if your mainboards vrm is crap and slow vdroop is helping to compensate this) and an overclock is more stable with it.

 

[lexluthermiester]

Anything you recommend or think I should try or leave it as it is?

I would call it a day if it's stable and runs cool. Though....

RAM at 2206mhz 9-10-10-28with 1.65v

...this bit is crazy. Above 1866mhz you get very diminishing returns. Bump it back down to 1866 or so with matching timings and bring that voltage back down too!

 

[dalekdukesboy]

First of all Welcome!!!Now I will suggest you to NOT buy immediately faster ram first install and OC yours 1680 V2 and see how far he can climb up because sometimes on those higher clocks(4,5Ghz+) if you manage to achieve that you maybe not going to be able to run much faster ram speeds....really depends on overall stability of your system and anyway on X79 ain't always that easy to go over 2133Mhz and gains are usually negligible in real life applications....so my advice is go slow step by step and then see IF you really need faster ram that you already have......

Ditto WELCOME!!!! Hell it's my thread I started least I can do is welcome you . I'm sorry to you and rest of you guys I've been a bit absent had a lot going on and some of that was using my system and not for posting/email so much . This is also excellent advice....high dram for this cpu/platform is extremely affected by your cpu mhz speed, higher you get the cpu to fly, the harder it is to maintain a tight timing and/or high mhz RAM setting. ALSO it makes a huge difference in heat I found...memory usually stays cool enough but the memory controller and all the strain on it and higher voltages on related settings really drive up your cpu temp!

On air...you're lucky to get 4.5 ghz with that cpu especially with the really nice speed and timings on your RAM! So good job! 4.6 + requires water period. Unless you have a car radiator and box fans to air cool your cpu.
