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

No, 4.9 ghz stable is a lot more voltage than is wise as well as an insane amount of cooling...I'd be impressed to see 4.75-4.8 ghz stable. I can do 4.75-4.77 or so myself but still tinkering with that. All I can say is that pc is a work of art, I could just ist and stare at it for it's looks alone even if the hardware was complete crap lol. Mine is such a mess in comparison...other than the rads though do you have many fans I don't really see any unless they are on side cover to keep VRMS and board itself cool.

Yeah was my first water cool build that one this year around May when Covid etc came in, thought I'd switch my gear over to something else... the other PC now in the second rig is below... always just used fans before. Nope, the only fans you see there are the rads, all exhaustive through the rads and create negative pressure who a few frown on, however for me, the vents in the Lian Li case allow them to suck the air in, never had any problems with temps in this thing at the moment so... long may it continue So basically it's 7 fans and all of them on rads and they are SILENT running 1,200rpm each.

Hahaha my fans are NOT silent atm I have a few screamers on it but I have them toned done with controller, what cfm are your fans? I also wonder what kind of pump you have and how many gph it does? Having 3 rads helps obviously but still I have 2 and I don't have my graphics card on one.

Airflow: 38cfm
Fan Speed: 1500(+/-10%) RPM
Sound Level; 23.5 dBA

Sure there's better out there and 100% way better fans, the Corsairs I have in the 2nd rig are something like 70cfm, but then they're so noisy... and it's always finding that balance.

The pump, not sure on the stats and I don't have a flow meter which when I upgrade to Big Navi I'll be slapping one in as I'm interested in the gph myself tbh. Haven't a clue, just a boggo Barrow DDC pump, dont' really know the specifics tbh.

You must have a powerful pump, because to run at speeds you're at with such low flow fans and if you're temps are good...then the loop itself is very efficient.

 

[Pugheaven]

You must have a powerful pump, because to run at speeds you're at with such low flow fans and if you're temps are good...then the loop itself is very efficient.

Yeah I'm only running the pump at 50% because this seems to keep the flow at the right point i.e. keeping the water in the rads long enough to exhaust but not fast enough that the flow simply pushes the water through the rads too fast and thus heatsoak into the pipes the case... which is NOT what you want. People automatically think that faster the pump is the better, nope... you don't want water spending most of it's life in the pipes, you have to get the flow rate right to enable the rads to do their job... what I've found is if I max the pump, the water temps go up, hence my theory previously... it's all about experimenting and also depends what's in your loop etc, thickness of rads, CFM, flow rate, ambient air... all adds up and it took me a while to realise that fast flow does NOT equal colder water as stupid as that sounds. The pipes keep the heat in, you in theory would want all your water in the rads and thus let them do their job!

As for temps... in a normal working office...

Just been running AID64 FPU for 30 minutes whilst 24/7 running folding at home on the GPU and the CPU temps maxed at on one of the cores 84C after 10 minutes... but thats' using the FPU stress test which is mental i.e. like Prime95 etc. That's also with the GPU at full whack in the look as well. When you run Prime95, AID64 FPU or OCCT benches, they're not really realistic BUT they're fantastic for stability and if you can control temps using those, in 24/7 use you'll be no where near those temps.

In Normal benchmarks they never go out of the high 60s i.e. I switched to the "Stress CPU" in AIDA64 and the maximum CPU temp on any core after 10 minutes was 68C which was also running the GPU 100% folding... That's in my room which was showing 19.5c as ambient if that's any help.

When I have the patio doors open recently when I was benchmarking, the ambient was down to 13C and the CPU's never go above 59C on full normal load...

True, I have logically gone through what you said in my own head before and realized there has to be a "balance" of good flow to keep replacing the hot water from CPU with cool water from rads/fans, but not so fast it just blows through and the rads/fans don't do their job properly cooling water...for heck of it, I have my pump on full I'm gonna try couple lower settings just to see what it does, I never have before

This is what my setup does with 4 gigs of memory tested with intel burntest and flow on pump on full....

Granted didn't let it cool down much but I ran same test with couple inbetween settings and always ran hotter, it appears if anything I could benefit from more flow not less...

As I said in another post your builds are really good looking....I'm going to have to bite bullet and show you the frankenstein wire monster I have! LOL. I will say I had to modify stuff and there are tons of fans so would be very hard to manage all those wires and hide them or route them in a good way! I'll do it however and bite my pride and just admit I'm a hack and a hayseed hick pc builder who's the equivalent of the guys with Trans Am's and Camaro's up on blocks with no wheels on them .

Just for shits and giggles I ran the Aida test and stressed everything but the disk and I have fans set on a curve and they rarely kicked in because the temp never went high enough long enough but two cores hit 78 degrees the rest were 74-77 so it ran pretty cool and that is at 4.75 ghz. I have to check which core is the one that controls the fans kicking in is it automatically core # 0? I'm honestly not sure, you just set it in bios the temps you want fans to kick in at and what percent they run but that's something I never really am sure of. At idle just fyi the cores are 25-33 so it's a pretty cool running rig overall.

Hey, anyone running a MSI Big Bang 2 here and was able to use commandrate 1 at ramspeeds above 2000+?

Even at 4 dimms i am not able to use commandrate 1, with my rampage formula 2800 was no problem with commandrate 1, same sticks.

What's your opinion on the 1680 v2 when compared to todays CPUs?
I'm thinking of replacing my 3930k for extra cores and small IPC gain, but looking at the prices they are still around 200€ - which is quite a lot of money for such old tech.
My plan is also to replace my GPU since it's not keeping up with todays games even for 1200p gaming (I like cranking up the graphics quality to max), so I was thinking of maybe going for the 1680 V2 with an RTX 3060Ti (still waiting for release and reviews) which IMO should be enough for 60fps and settings maxed out.

The alternative is the 1650 v2 which goes for under 100€ - but I don't gain any core count or significant cache increase.

 

[bobbybluz]

I have two 1680 V2's. They destroy all other X79 CPU's. Performance is extremely close to a X99 5960X at the same clock speed. I got mine off Ebay for $150 USD each.

Hey, is this with 125 bclk and125 strap or 100 / 125? If it is 125 / 125 how have you managed to get your vcrore to drop while idling? with my formula the idle voltages are gone with 125 / 125

This is with 125 strap and no idea how it even did that....I wondered myself how it happened when I took screenshot and noticed it lol.

 

[agent_x007]

When multi is fully unlocked, strap doesn't matter that much.
On my board, strap at 125MHz makes Vcore static (while 100MHz works fine while idle) :/

 

[drizzler]

yeah that how it usually works, maybe just a cpu-z bug @ screenshot

Hurry up and get a 1680 so we can see it lol. Seriously though I hope you can find one for a reasonable price and use it, you will notice the difference...

I also have a random stupid noob to watercooling question, can I install a 2nd pump (I know I can) but would it help me at all if I suspect my flow is less than optimal going through two pretty big rads?

 

[bobbybluz]

Somebody has more than 10 on Ebay for $150 USD each but no free shipping. https://www.ebay.com/itm/Intel-Xeon...976682&hash=item1aa030ddb7:g:XOIAAOSwwoledH1L

 

[repman244]

Yes I saw that, but after import duties, the price is the same if I buy it from Germany.
Still haven't decided if it's worth to upgrade my CPU and stay with X79 or build a new system which won't be cheap since I want to stay with a similar system (quad channel RAM and high number of PCIe).
And looking at the motherboards for newer systems - they don't even offer the same number of PCI-e slots as they used to.

 

[TheUnbrained]

well, since this isnt my main setup anymore, i went for some ocing, the results are...interesting

Limits: 4,9GHZ for 1 core, 4,6 for 4 core and 4,5 for all @1,385vcore

actually dont know if this is good or not, i mean the vcore is rather high

p.s. this is still so much more fun than ocing haswell-ep ...

 

[Zyll Goliat]

Hey guys just to let you know I upgraded my CPU from Xeon 2650 V2 8c/16t to the Xeon 2697 V2 12c/24t....also I managed to OC this cpu via bclk on 115,2Mhz bus speed so cpu now working on 3,456Mhz on all cores + turbo boosting up to the 4,032Mhz and it's 100% stable on only 1,175v
here some benchmark-results bellow....




Temps are also great....under heavy-load in Cinebench R23 loong runs CPU max temp was 77c on my modest air cooler....

Hey there,

I just bought a Rampage 4 Extreme and a 4960x (engineering sample) for some cheap money, paired with 2 sticks of Corsair 2x8gb 2133mhz c11

Everything is running fine with a light overclock at 4.0ghz all cores but I can't higher > when I set ratio to 41, with whatever settings change in bios, it doesn't even boot or post, just infinite restart and I have to clear cmos to acces bios again...

Should I try BCLK overclock or is this an ES CPU issue ?

And btw, you talk about Xeon E5 1680 v2, but what about an E5 2667 v2 ? Looks the same on paper

 

[Zyll Goliat]

And btw, you talk about Xeon E5 1680 v2, but what about an E5 2667 v2 ? Looks the same on paper

Xeons E5 2600 series are locked cpu's and basically you can OC them but only via BCLK and that depends how good particular chip is,your mobo,memory....usually on BCLK you can expect somewhere around 103-105 but sometimes it is possible to reach more... I have 2650 V2 before where I managed to OC on BCLK up to the 113,4 and now I have 2697 V2 that goes up to the 115,2(Golden Cpu)that gives me 3,456Mhz on all 12c/24t cores and turbo up to the 4,032Mhz on few cores which is Great but still 1680 V2 easily can hit 4,2Ghz-4,5Ghz and with a bit of tweaking you can see that some guys in here hitting much higher speeds than that....
P.S.if you or anyone else is interested I tested both of those Xeons so you can see the results when they are OC and how that is compared with today's cpu's
Link:"Old"Xeon 2697 V2 and Xeon 2650 V2"Overclocked"and Benchmarked!!!

Well you can try BCLK and see how that goes also maybe you need more"juice"on your Vcore,VCCSA,VTT,PLL.....but it is possible that your particular chip can't do more then what you already achieved considering that is ES it is quite possible ....If you have time to play with OC and you like it then go for it man,your motherboard is just perfect for that just stay safe with the voltages......GL

 

[j1n101]

The previous owner was running everything at stock voltage and frequencies, so I don't know how this ES CPU is limited (I've heard some ES were good for oc too)


The 1680 v2 is still quiet expensive at the moment, do you know which xeon 6c/12t is unlocked ? Because if I have troubles with my current CPU maybe I can purchase a similar xeon to seee how it goe

 

[Zyll Goliat]

Well basically All series 1000 is unlocked now when it comes to the 6 cores you can go with Xeon 1650 which is equivalent to the I7 3930k or you can go with the 1650 V2(4930k/4960x)....they are pretty close in performance tho' all V2 Xeons are done in 22nm which means less power/heat then older 32nm tech.....but my advice to you is first try a bit more tweaking and OC your current 4960X and see how that goes....btw. your CPU is X and have a bit more L3 Cache(15mb) which should give you among other things a bit better performance in gaming.....
