Thanks! Happy with how it all came together.

Chapter 8 - Finale It's all done! Finally had some time to sit down and complete this bad boy. I'm really happy with the end result. A LOT of work, but I think it paid off. Here are some final pics below

It's been way too long, and life's been way too busy (new job, new house). But I've finally found time to work on this build. The loop is full, custom cables (bar one) have been cut and the modded side-panel is ready to go. I'm going away on holiday for the next few weeks, but anticipate having everything completed in a month. Here's a little pic, I'll wait for completion before posting many more: And a small teaser for my next build:

Ok, beginning to narrow it down. When running in Crossfire, the system will crash when GPU one is at ~61-degrees and GPU two is at ~55-degrees If only GPU one is enabled, there are no crashes, even when pushing the GPU to~63-degrees using FurMark When only GPU two is enabled, the system crashes at ~55-degrees. The issue? GPU two. Why? Still no clue. Why would it work perfectly up until that mid-50 point, when total system failure occurs? I'll try take everything apart tomorrow and see if I can see something. Perhaps an o-ring has slipped or something. The backplate feels pretty darned hot, so I suspect that the graphics memory temps are significantly higher than the seemingly fine GPU temp

Thanks, will give that a go! Testing the GPUs individually I think I've noticed something. It isn't the first GPU causing the crash at 60-degrees, I believe it's actually the second GPU at around 54-degrees which causes the crash. I'll stress test the first GPU further but it seems, at least at this point, that there is an issue with the second GPU.

I'm using MSi Afterburner for all monitoring, and I'm confident the temps are correct. I'll try unplugging one of the GPUs and testing again, but I suspect you're right and the MoBo will throw a hissy fit

Update: Some more testing was done. This time I limited the framerate to 55 using CCC and set all details to low (using Unigine Heaven). This resulted in temps not exceeding 52-degrees, and not crashing once. It definitely seems like there is some sort of thermal issue.

Thanks for the advice. Unfortunately, as I mentioned before the system is watercooled (with acrylic) so swapping cards in and out isn't the easiest endeavour. I've tried a variety of drivers and reinstalled Windows. Same issue. Also, nothing higher than a 750W lying around, and I don't think that's enough to really test out the system. I think I may have made a diagnostic breakthrough of sorts. Three times in a row now the artifacting has begun when GPU 1 hits 60-degrees. I've set Overdrive to have a much higher thermal target than that, so that isn't causing it. Any ideas? What would lead to such instability upon hitting only 60?

Pretty sure everything is out of warranty. 5 years on the PSU, both the graphics cards have custom water blocks on them (and worked perfectly in the previous build). What do you mean about the PCI speeds? hasn't 8x/8x been proven to be more than sufficient?

Yep, not concerned with the wattage, just the age. I've had it since 2010 in regular use. Will wait for some more feedback from others though

Absolutely everything is currently running at stock. And yes, I normally relate artifacting to GPU, but as a result of power issues (e.g being pushed too far)

Hi all, Hopefully someone can either confirm my suspicions or point me in another direction as to what could be the issue. First, my specs: CPU: Core i5- 4670K (not OCd) RAM: 16GB Kingston HyperX @1600MHz MoBo: MSi Z97M Gaming with latest BIOS Graphics: 2x R9-290s in Crossfire with latest drivers (not OCd) PSU: Corsair HX1000 Windows 7 Home Premium x64 with SP1 Basically, when using my PC for regular things (watching movies, browsing the net etc) everything runs swimmingly. However, when I start a game artifacting will begin to occur after 5-10 mins (depending on the game) and then the whole PC will crash within 5 seconds. Some things to note: Disabling crossfire stops this from occurring locking framerate either prevents the issue on some games OR delays it on others Have run memtest - no issues Have tried many different drivers and reinstalling Windows What do I think is wrong with it? I think it's the PSU beginning to die, and when the power draw gets too high it croaks. However, Corsair makes incredibly reliable PSUs and at 5 years old, I figured it may still have a few good years left. Any thoughts? Thanks!

Sorry I haven't updated in a while! Been busy on other projects and just chipping away at this when time permitted. Progress has been made, however. Here's a little update pic. Cat + PC = good times Also completely rearranged the internals and began some new tubing routing. There's some custom acrylic work done on the inside, but LOADS more to be done on the exterior, particularly the front panel and to cover the externally mounted fans. I've actually become really happy with how it's turned out, so I'll probably end up bumping up the graphics to something beefier. 980Ti or AMD Fury. I'll probably put it to a vote on here, so stay tuned for that

Just sitting here waiting for Fiji, twiddling my thumbs.

Yep, would be temporary while I get a matching black sparkle version. However, I've changed it to a right angle black sparkle fitting instead!
