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

[aQi]

Hey all, hope you’re having a good week finally getting some warmer weather here been very cold in spurts. Barely been home been with the fiancé and family which has been nice but I will also be happy to get some time at home and play with my pc again

Yeh man you said it i was waiting for the weather to get a bit warmer. If feels good when external temps do not bother. I get kick by extreme colds and extreme warm situations.

So what configurations are you planning to play now ?

It’s in the 50’s here after being barely double digits for week or two…not sure exactly what you mean by the configuration question but I am putting together a new 12900k system from scratch and also tweaking and adding multiple fans to my old 1680v2 setup…When I get back home which will be today/tomorrow at some point I’ll take pics of what I’ve got and what I’m doing. Also just ordered 2 new power supplies I like the corsair 1000 watt I’ve got but with the 6900xtx I’ve got and the big overclock and watercooling etc I think it may not be providing enough power…especially when the recommended minimum for my gpu happens to be 1000 watts. I’ve noticed some weird behavior from my Gpu when gaming like at some points not using anywhere near 100% utilization plus had some shutdowns and issues with pc and only way to know if it’s the power supply being inadequate is to upgrade it. So, I’ve got a 1600 watt sitting there and just ordered a 1350 and a 1600 watt because I like having what I need and having extras and I literally only had the corsair power supply till I ordered the other 3, and I will have 2 systems so needed at least 2 power supplies and the extra is good to have on hand just in case.

Is it because of this pin that RBE 4 teases and stabs me at the start.

Where is this beast now ? And arnt those cards connected

 

[Xeon]

This beast is long gone, I've sold the mobo+cpu (4930K)+ memory back in late 2015. I've actually rebuilt it after taking this pic. I had to move it from the corsair 750D to a 900D because I needed dual psu's...if you look closely you can see the 2 bottom GPU's pcie cables were routed outside the case, These GPU's (R9 290) didn't need a crossfire bridge and fun fact one of these still lives on my son computer the other 3 were sold aswell.

Sounds strange 1000w was fair enough though considering whatever system its supports there is still some maths to be done before you go more power which I assume you might have done. Lets us know if upgrading the PSU resolved your issue

Yeh i saw those cables moving out but i thought may be they were twisted. Well now i get it radeons did not need that bridge to crossfire. Supposingly i guess that radeons provided more juice over gtx though never seen those r9 295 in crossfire freaked up.

Oh man, wasn't expected to see those here

Coincidentally this is the card i got just a week ago

Bought it from a guy that had it from day 1, was one of those full 290X chips inside 290 so I got to unlock it too.

 

[Xeon]

You're lucky, none of my cards unlocked to 290X.

Here is a video of a 4K Tomb Raider benchmark, with the original system that was Trifire before i added the 4th.

 

[KptRex]

none of my cards unlocked to 290X

Yeah from my knowledge it was only first few bathes on relase and some later sapphire modeles that got full 290x cores inside

Bay the way how did the utilization on those card looked like. Any noticeable gain from adding 4th card? From my experience with HD5970 on 2 chips it worked quite well if game was optimized for it and horrible if they waren't, never had a chance to go with 3 and more so interesting to see how it worked out

Oh and power consumption of whole uint with temps, super cerious about those

These were from the very first batch available locally from November 2013! 3 and 4 cards work great when the game was optimized for crossfire, or it would be a pig but no point on getting a trifire or quadfire setup with a pony 1080P screen, I've started with 3 cards and an eyefinity setup (5760*1080p) when I upgraded to a single 4K I felt that it could benefit from the fourth card.

Not sure why you are super serious about power consumption and temps? These cards are a decade old by now they have no official driver support and even on Linux they're starting to be flaky, just get a more modern card.

I have two sets of 16GB Corsair DDR3 2400 RAM. One is CAS9 Dominator Platinum 4x4GB set and the second set is CAS11 Vengeance Pro 2x8GB. I need 32GB RAM and a matching set of the identical DIMMs. I have one of the following options. Which route should I go?
1) I can exchange CAS9 Dominator 4x4GB set for another 2x8GB CAS11 Vengeance Pro set locally so I will have a matching 4x8GB set.
2) I can purchase another CAS9 4x4GB Dominator set from eBay. The revision number matches with my kit. Will 8x4GB DDR3 2400 even work at CAS9?

 

[pevac]

It will work without problems

The Corsair Dominator RAM is arguably the best DDR3 ram ever made for a X79 motherboard. Only little quirk with this motherboard I've found is that with the installed Xeon, it only runs the RAM in the red dimms.

I own two i7-3930K processors. 1st can do 4.5GHz at 1.26V, but 4.7 GHZ at 1.35V. 2nd one can do 4.5GHz at 1.28V, but 4.7GHz at 1.32V. Which one can be considered golden chip? Which one should I keep?

Is anyone running DDR3 2400 in this thread? I own E5-1680V2, Rampage IV Black Edition and Corsair Dominator 16GB DDR3 2400 CAS9 kit. When XMP is enabled and everything else is set to Auto, CPU VTT is around 1.26V and VCCSA 1.15 under load. How are your VTT and VCCSA set in BIOS? I have read elsewhere that over 1.2V on VCCSA/VTT is deadly for Ivy-Bridge CPUs.

My CPU can run Cinebench R15 at 4.6GHz at 1.27V. I enabled the XMP setting and dialed in the known good OC settings for 4.6GHz with VTT manually set to 1.10V and VCCSA to 1.05V. Windows Memory Diagnostic ran without any errors. But Prime95 Blend test failed within minutes because several workers stopped. I dropped down the CPU frequency to 4.5GHz. Prime 95 Blend ran for 15 minutes before failure. I upped VCCSA to 1.12V. The test run for over half a hour before the worker stopped due to rounding error. I upped both VCCSA and VTT to 1.15V, but Blend failed within seconds. I upped both VCCSA and VTT to 1.20V and PLL to 1.85V. After 25 minutes, the PC suddenly lost power and restarted. What is happening?

I googled for info and read on another forum that even 180% Current capability is too low for E5-1680V2 on Rampage IV black Edition, so you apparently have to disable it to fix intermittent shutdowns.

 

[pevac]

Cinebench R15 is not prime 95, increase the voltage on the CPU

The second. The 1.28v is a good low voltage, but the 1.32v for a high is better as that will keep potential circuit pathway degradation to a minimum.

I had some 2133 at one point, but the 1866 had better timing and tested better so that kit was sold. DDR3 1866 with 8-8-8-24 or 9-9-9-27 timings are sweet spots. DDR3 1600 with 6-6-6-18 or 7-7-7-21 would be too.

That's excellent as long as the voltage isn't too crazy. Got a model number we can look at specs of?

 

[wanna_buy]

My kit model is CMD16GX3M4A2400C9 and the rated voltage 1.65V.

I don't understand. If VTT 1.10 and VCCSA 1.05 are too low, then the system should not boot and Windows Memory Diagnostic should not pass flawlessly, right?

 

[lexluthermiester]

1.65V

Holy crap! Ok, that's some serious voltage. What's the XMP profile say about 2133mhz?

 

[wanna_buy]

Holy crap! Ok, that's some serious voltage. What's the XMP profile say about 2133mhz?

Are you aware of any DDR3 2400MHz modules that can run at 1.5V? There's no 2133 MHz profile, only JEDEC low speed and XMP 2400 MHz profiles.

 

[lexluthermiester]

Are you aware of any DDR3 2400MHz modules that can run at 1.5V?

Nope. The implication was that you should try to lower that voltage to 1.55v and try 2133mhz at the same timings. 1.65v is a bit too high, even for the 3930k. While the RAM voltage problem was not as serious with socket 2011 like it was with 1366, it is still something to be cautious of. The bandwidth drop from 2400 to 2133 would not be noticed, but the voltage drop would ease stress on the IMC and lower temps.

There's no 2133 MHz profile, only JEDEC low speed and XMP 2400 MHz profiles.

You can still adjust RAM speed in the BIOS though. Was just wondering if it had a profile for 2133 as that would take the guess work out of making an adjustment. Still, you can set the XMP, then before saving the settings and rebooting, change the voltage to 1.55v and the RAM speed to 2133, leaving all the other settings alone.

You have apparently missed this post where I state that I am running DDR3 2400 in combo with 8-core E5-1680V2. I am not using i7 3930K. I played with i7 3930K for fun, but I plan to use 1680V2 for my new rig.

 

[lexluthermiester]

You have apparently missed this post where I state that I am running DDR3 2400 in combo with 8-core E5-1680V2

Yes, I did. But that doesn't change much. The IMC in the 1680V2 is still sensitive to RAM voltage being to high. I've seen what happens to CPUs with high RAM voltage. The performance starts to degrade and then one day, the CPU just fails to boot.

 

[wanna_buy]

I did an extensive testing using Prime95 v26.6 which is the last non-AVX version. I decided to test DDR3 2400 stability with VTT manually set to 1.10V and VCCSA to 1.05V. The CPU was at stock, but with the XMP enabled it was running at 3.9 GHz Turbo. Prime95 Blend test ran without any errors for more than 2 hours.

Previously I have used Cinebench R15 for quick stability testing. While the RAM was running at stock 1333 speed, my 1680V2 could pass Cinebench R15 at 4.5 GHz at 1.23V and at 4.6GHz at 1.27V. I now reverted the RAM speed to default 1333 MHz. However, Prime95 Blend failed even at 4.5GHz at 1.27V. I upped Vcore to 1.29V and Prime95 Blend ran for 23 hours without any error. Now I am going to test both CPU at 4.5GHz and RAM at 2400.

Yes, I did. But that doesn't change much. The IMC in the 1680V2 is still sensitive to RAM voltage being to high. I've seen what happens to CPUs with high RAM voltage. The performance starts to degrade and then one day, the CPU just fails to boot.

I have read pretty much elsewhere that 1.65V is the max safe voltage. However, you should keep the gap VCCSA and DRAM voltage no larger than 0.6. So I have to set VCCSA to at least 1.05V.
