Archimedes block install, Cooling upgrade for "Behemoth" - Page 4

I've come to the conclusion that the issues I was having with my RAM was indeed a slightly bent pin that wasn't quite getting the right contact with the pad on my CPU due to the dielectric grease in the socket. Through months of running ram at 1600 and the heat cycling that goes with it, the pin has now got perfect contact again and I'm able to run XMP 2600 10-12-12 and beyond again. So, I need to crank this CPU core up a bit, plain water cooling is good for 4.8ghz, but beyond that it doesn't respond well to voltage, however when I had the TEC block on I was able to game and bench at 5.2ghz, stable at 5.1ghz. I'll leave the IHS on the CPU this time to avoid any issues with ram/pins etc.

I have also retested my TEC controller and it is indeed able to handle the 19940 TEC at 12v, I must have has a short somewhere before that was causing the controller to not work, I just assumed the 20a limit on it was causing an over current protection to come in, but it turns out there is no protection and it will run whatever you throw at it till it burns out, so I'm now able to handle the 12v 24a at startup before it settles down to 12v 18a at 100% CPU load with about a 25*c delta below ambient.

Too much pressure on the chip will cause it to bend and I've noticed with mine and heat cycles that sometimes my PC will crash then fail to boot when voltages really run up high, my 4670k is also naked and bare die with an ek wb. I also want to do the same as you Liam and get myself a TEC setup and run it 24/7. I'll be PMing you in the not so distant future I think. thumb.gif

hit up foxrena to make you one or sell you one if he has any left. highly reccomend his blocks and this TEHC19940 TEC is perfect for quad cores.

My troubles were purely because of the dielectric grease in the socket, its really packed in there, so if a pin gets slightly bent or even just depressed and prevented from springing back by the grease you get bad contact with the CPU and usually results in ram issues, I wasn't overly tightening the socket, and I was pretty careful to keep it flat, but when I changed my loop I think I pressed the block while it was in place to tighten a fitting and it might have just squished some grease in between a pin enough to cause problems. When I switched back to plain water I didn't clean the grease out so the problem persisted. Through heat cycling and perhaps some luck that the pin sprang back I'm all good again. Collecting parts to do a hard tube build with the TEC block in a phanteks evolv atx case. I'd love to get a 15v PSU to really keep the cold side temp sub zero even with the 4670K at 100% load.

I will be following that because I want to put a TEC on this i5 or 6950x for 24/7 I don't want to go sub ambient temps though, I want a rig that looks good while performing just as good. I'm going to have to pick your brains on how I'm going to achieve this though as I don't know anything about TEC cooling. redface.gif

TEC is pretty simple, get a nice custom water block, get the biggest, baddest TEC you can find, run it at 35-75% of its Umax (max voltage), use a PWM controller to keep it around ambient, the controller I use can be set at any temp you want. learn how to insulate your motherboard just in case, most importantly, learn the limitations, ie using a direct die TEC on a 6950x is going to be difficult, but if you only want to get around ambient temps it is doable. It's perfect for your i5 but it may not be worth the cost to spend that much on an i5, I did and I'm happy with it but if I tally it all up I could have a 6800k system easily.

Still waiting on evolv atx to come into stock, plus now they sold out of 16mm tube, hopefully in a week I can place the order if it is all in stock.

But you could use that tec on another rig couldn't you like a 6800k? I need money first and foremost. biggrin.gif

Yes I can use it in future systems, which is how I can justify it, but it is certainly a costly hobby, I do it because I enjoy it and it's a nice challenge. I'd love to build a chiller but the cost is prohibitive to do it well. I think I'll lean more towards staying above dew point in future just to keep it practical but still being beneficial.

I'm planning on a future move to AMD ZEN provided it turns out well, bit tired of Intel and want to mix it up a bit, if it has similar IPC as my haswell and is 8 cores/16 threads for a decent price and can be OC'd well with good cooling then I think I'll migrate to ZEN.

well I have always had one intel system, and one AMD system that I build at the same time, currently I have a AMD FX8350 system at stock speeds of 4Ghz, and that runs at about half the speed of the intel 3930K also set to 4Ghz, they both had 2 GTX580 video cards and 1600Mhz memory. so, the only real difference between the two systems was the CPU. the last time I had a AMD system that outperformed the intel system, was the AMD FX60 2.6Ghz Vs. the intel extreme 3.73Ghz the AMD system had a 6800 pro video card with DDR 400Mhz memory, and the intel had the 6800 ultra video card, with the DDR2 533Mhz memory. at the time the AMD CPU was 999.99 processor, and the intel CPU was 999.99, but the AMD system ran most games better, and faster than the intel system. today unfortunately intel seems to be twice as fast, or more than AMD systems, maybe in time that will change. if it does, than I am sure that we will see a increase in the price of the AMD processor to match. AMD seems to know when they have a comparable product, and prices there product to match intel's counterpart.

You simply shouldn't have an FX at stock, they need to be overclocked, get that thing to 4.8ghz you'll see a difference, 5ghz keeps me 5fps behind my overclocked i5. I suggest going to the fx 8350 owners club an giving it a read on how to set up the 8350, once you tune up RAM and the motherboard clocks you'll see a good difference. thumb.gif

provided you can cool the beast tongue.gif

as I said, hopefully ZEN has haswell IPC or better, if it has haswell IPC I'd be happy because it's very solid performance, more cores/threads, but also as it is a generation or three behind intel IPC it might keep the prices at a reasonable level. If ZEN miraculously is skylake IPC then they will be priced to compete with intels best.

I want them to be level with intel tbh, intel chips just don't seem to be improving much considering AMD have been out the game so called....

5fps from my amd to my i5 even though the amd is a generation behind? hmmm not to impressive.
