Asus Rampage 3 Gene Xeon X5675 overclock?

[Mr.Scott]

Had to bump the voltages, stable now for a few days, playing Fortnite usually crashes within a couple rounds when it gets hungry for voltage getting 120-140 FPS epic settings shadows low
CPU 1.46250 V
CPU PLL 1.90 V
QPI/DRAM 1.35 V
DRAM Bus 1.64V

I like your voltages as long as you can cool it.
I personally would bump the vdimm to 1.7-1.75v simply because that voltage usually sags, and more so with 6 sticks going.

running a 120 mm Cooler master AIO mounted at the back keeps it in the 60-70c range during gaming would do better with a 360mm at the front and use this 120mm to cool my RX570 on my other rig
these dims are rated @2133 1.6v I'm underclocking them @1969 I don't think it would be safe over 1.65v I damaged one X5675 leaving the DRAM voltage set to auto

I have one but it won't fit with the AIO in the rear. temps are good this is after 1:48min of gaming with Fortnite running in the background I have MSI monitoring the hottest core #2. using an inferred heat gun getting below 60c on VRM and chipset. this case has great air flow I currently have the three 120mm front and two 120mm top intake fans one 120mm rear exhaust for the rad. soon to get two noctua A12 black fans for the top intake, also have slotted PCIE slot covers at the back to help vent and direct air past the chipset heatsink

 

[Keullo-e]

I do need a better case for that rig but can't afford one now. I'll also get something with good airflow as the current Define XL doesn't have that good of an intake. CPU can get over 90C easily, even under water.

I've had 1.71v vdimm running for years now on my X5675's. No issues at all.

 

[freeagent]

I am ok with 1.725v for extended periods on BBSE. I did baby my STT Chromes though, I never gave them more than 1.7v.. I should have gave them some more though but always had the fear that my Hypers were the ones that died, but 10 years says probably not

 

[Keullo-e]

My HyperXs (3x2 + 3x4) run so damn hot that I just don't want to bump their voltage any higher. Probably a RAM cooler would be a thing.

 

[DirtyBiker]

Anyone know where I can probe for CPU, VRAM, QPI/VVT, voltage on the P6X58D-E motherboard?
Thats what I like most about the Rampage Gene III it has dedicated Probe points

No idea, I don't even have a multimeter..

well, I have to live with 2 front fans in my Cooler master CMP 510 one of them makes an annoying hum and vibration sending it back for RMA see how long it takes to receive it back funny thing is I looked on their web site and they don't sell or even list these fans??? while I was in there I replaced the thermal paste in my GTX 1080 dropped fan speed about 500 RPM I want some kind of cooling solution for the GDDR5 chips on this card, I was thinking thermal pads but there's a big gap between them and the heat plate and would probably end up blocking air flow to them, GPU hot spot is 80-85 during gaming I assume that's the ram temp anyone know of a solution for this?

It's not uncommon that bundled case fans aren't sold separately.

GPU hot spot is literally what it says, doesn't have anything to do with the VRAM. But having thermal pads between the plate and the GDDR5X would probably help at least with overclocking. Which model your card is?

My G-skill 2133's don't even hit 40c measured from the hear spreaders and the back of the motherboard

My HyperXs gets so hot that I can't even keep a finger on them for long.

You got the card used? It should have thermal pads... https://www.techpowerup.com/review/asus-gtx-1080-strix/4.html

Yes, used super clean paid $395 Ebay. it does but not on the ram chips, from what I have read no worries until over 100c on hot spot, even at stock clocks it hits 81c no difference overclocked only 3% higher fan speed still would like to lower it to quiet the fans a bit

HaHAHA I found out where coolermaster sources these fans
Amazon.com: EZDIY-FAB RGB Dual Ring 120mm Case Fans,5V Motherboard Sync,Speed Adjustable,RGB Sync Fan with 10-Port Fan Hub X and Remote-5 Pack : Electronics

Well no crashes yet sense I upped the CPU voltage and just placed #3 on fire strike for X5675 + GTX 1080 all time scores, I need to work on air flow in this case now, I had to pull the bottom front case fan for RMA and I can feel it hot exhaust air coming out of the PSU basement I might just reverse the flow the two bottom fans powered by the GPU fan headers that will give me 3 intake and 3 exhaust, I don't want to force the GPU exhaust through the radiator I will mount 2 black Noctua NF-A12x15 PWM intake fans powered by the 4 pin motherboard case header at the top to feed fresh air into the radiator

 

[DirtyBiker]

OK no more crashing well almost none tried lowering voltages, but this is efficient as she will get, flipped the two lower front case fans to exhaust hot air from GPU under load, powered by the GPU, they only come on when GPU reaches 65c, stock GPU fan curve, the temps do get lower with MSI curve but at 100% she gets noisy without much effect. two top mounted 120mm filtered intake fans and one front top 120mm intake fan behind mesh not really filtered powered by motherboard case fan heeders, all unused PCIe slots are vented and act as intakes during heavy GPU activity and exhaust when GPU is idle (smoke tested). My Samsung 950 Pro M.2 NVME drive with heat sync is mounted just below the GPU so it's a good indicator of air temp reaching the GPU intake fans (my other silicon power SSD temp is not active always reads 33c), screen shot left taken with Fortnite running in the background after a long session and victory royal screen shot right Idle temps fan speed case fan curve set to standard, CPU fan set to manual 40% 40c 100% 60c keeps it quiet when not under heavy usage. I haven't had time to return my RMA case fan but with it only coming on when the GPU is loaded you can't tell the difference over the other fans when they ramp up. I plan to just drive to Cooler master there close to home, maybe they can set me up with some swag I would like to get some Cooler Master fan stickers to place over the stickers on the back of these fans because they face forward but you really can't see them, they are ring fans with LED rings on both sides. next mod will be spring loaded CPU cooler mounts, I need to find long enough bolts and some heavy springs to give equal pressure to the GPU block I have the nuts and spacers and the nuts have recesses for springs to locate. this AIO didn't come with socket 1366 hardware and I don't want to over torque it. maybe Cooler Master has the right hardware at the main office that would be nice.

 

[DirtyBiker]

I wasn't happy with the CPU@ 1.4625v so I got the voltage back down to 1.45v by upping the CPU/PLL to 1.96v played a couple rounds of Fortnite no crashes yet may try and lower it a bit more later if no crashing also downloaded the ASUS Strix GPU tweak so I could adjust the two external exhaust fans to come on 60% @50c, 100% @70c works well to bring down the GPU temps minimal noise
(((( update that didn't prove stable went back to previous settings ))))

 

[DirtyBiker]

Well, this is what I came up with idle temp's vs temps after Cinebench R15, power supply RPM is actually AIO pump speed

 

[DirtyBiker]

Huston, we have air flow, I reconfigured the fans again I was getting a dead spot under the GPU, so I flipped one of the 2 top fan closest to the front to exhaust, now it gets mad airflow, check out the samsung SSD temp it's mounted in the PCIE slot just below the GPU fans, now the middle and top front fans and one top fans act as exhaust, they only come on under GPU load, powered by the two GPU external fan headers, there set to come on 50% @50c, and 100% @70c. the other top mounted PWM fan is set to intake just above the radiator it feeds cold air directly above the AIO radiator, the Bottom front case fan is 3 pin motherboard powered feeding cold air under the GPU and somehow it's still positive pressure under load, the slotted PCI slot covers blow air under full load and idle, at idle its two in one out and under load its 2 in 4 out what's, cool is the top mounted exhaust fan is an old Antec Molex powered case fan with a speed selector switch, but sense the Cooler Master front case fans have 3 pin and Molex daisy-chain, I was able to plug into there so it's now acting like a 3 pin GPU powered fan, I also flat lapped the AIO pump and CPU IHS with a 120 grit finish. I had made a steel lapping block that I surface ground then flat lapped on a glass picture frame with the 120-grit sandpaper and red diamond compound then used red diamond lapping compound to get the heat sync and IHS flat, then finished with a couple light passes on fresh 120-grit sandpaper for adhesion of the thermal paste here's the results.
Question does anyone have any experience using liquid metal on copper?
I was thinking about using an Oring around the CPU IHS to keep the liquid metal from leaking out and lube the Oring with standard thermal paste to create an airtight seal.

((((Update)))) speed stepping and C-state working great to keep power and temps down, no crashes yet and the new fan config is solid, I just need to save up for those 2 black Noctua NF-A12x15 fans, the one RGB Cooler Master fan from the AIO I use as a top intake is a bit noisy, it doesn't like being so close to the grill and I'm sure they were not designed to be mounted vertically. next phase of the build is quiet as possible. I may only need to get one Noctua fan because I like being able to switch down the power on this Antec Molex fan to tune the air flow and its black, where it's mounted no one would be able to tell the difference because it only comes on under load its equally loud if not quieter then the Strix 1080 when it spools up its triple fans. I may even go with two 140mm top fans, quieter and more air flow. also picked up these Swiftech socket 1366 pump mounting screws on Ebay I hope there the same metric thread as my current back plate there's nothing in the description about thread pitch or dimensions, the AIO pump is plastic so I like the Idea of spring retention, it can expand and contract better and provide equal mounting pressure, I've seen reviews about the plastic around the pump breaking, I'm surprised cooler master didn't go this route.

I decided to try max overclock with the CPU voltage set to auto (Max 1.35v) as well as speed stepping and C-state enabled ended up with 4.31Mhz 50 point drop in Cinebench R15 but was able to keep the ram speed close to what I was getting @4.53MHz and lowered the latency to 48ns from 50ns, also dropped the QPI/Dram @1.331v, DRAM @1.6v temps are much less stressful with no noticeable loss in gaming performance testing COD war zone, Fortnite, Doom, Halo infinite, Apex legends, even at 4.33MHz had to boost voltage to 1.37v QPI/DRAM 1.35 DRAM 1.64v with little to no performance gain in benchmarks I think we found the sweet spot for this combo is 4.31Mhz for performance and power efficiency

Lol. Thats funny. Pretty sure I said that way back in this thread.
Here's mine again.

 

[DirtyBiker]

It's a learning curve

 

[Mr.Scott]

It's a learning curve

And you had fun.

 

[DirtyBiker]

I have to admit it's kind of addictive pushing the limits at least knowing I only paid 12 bucks for the CPU don't know if I would be so adventurous if I paid retail price back in the day I always enjoy pushing the limits of my dirt bikes my cars and now computers, my nephew's in college at the moment and doesn't have room for a PC but he's graduating in June and this is going to be his job well done gift so I want to make sure it's rock solid for him he's the one that got me addicted to fortnite well kind of I just use it as a benchmark tool hahaha but it's still pretty fun I actually like dying and watching the guys play while I closely monitor performance statistics some of these players are pretty amazing
