Haha.. Fair enough! Thanks guys and / or girls! It's good to know I've got some headroom to play with. I'll push it some more in a few months then, but for now, should I be worried about the FPU AIDA64 stress tests? What does the FPU actually test or do? I read somewhere it pumps Prime95 level voltages (the bad kind) into Haswell-E chips.. Is FPU not a good option to select, or is my OC not as good as it could be? Ps. I just noticed the core voltage sits at 0.973v at idle too, went up to 1.246v, and the Max temp was 72, average temp hovered around 66. I'm guess I'm fairly happy!! 8D ChrisDiz

Hi All, I'm new to overclocking and PC building, but have got my i7 5820k to 4.5Ghz and it's not crashing in Unigene Valley, Heaven, 3dMark Time Spy or Aida64*. Parts list is here: http://uk.pcpartpicker.com/list/rT8wcc At idle, the temps run around 28 to 33 degrees. I've upped the CPU multiplier to 45 and memory to XMP profile 1 (2666Mhz) and it runs at 72 degrees indefinitely (over 3 hours so far) with CPU, Memory and GPU tick boxes selected (not FPU, cache or local disks). Also, I've pressed the physical GPU higher power limit button on the graphics card, I'm running the graphics card at 1100Mhz via Trixx, and I've upped the Trixx software power limit to +50%. I haven't changed any other settings, and the CPU core voltage builds from 1.19v to 1.243v in CPUID. I believe the core voltage is set to variable voltage as again, I haven't changed anything else. However, When I run the AIDA64 system stability test with every tick box selected aside from "stress local disks", the system will crash within seconds, hence the asterisk (*) above. When I'm gaming or running the visual benchmarks mentioned, It's not crashed once for over a month now.. only while stress testing above in AIDA64 with FPU, Cache and local disks selected . Should I just leave it be and be happy with the OC (and likely start gloating), or does the FPU or Cache test crashes indicate a problem yet to surface if / when I start encoding videos. All the best, ChrisDiz

Solved!!! Aaaaand the problem was.... A tiny speck of dust in the cpu socket?! I'd checked all the pins with a torch up close, and they were all uniform, looked from different angles.. Looked ok. But the kicker was I called someone out.. They came during the daytime, and with the motherboard near the window, he saw this speck of dust which I hadn't seen at night.. A gust of compressed air and we moved it.. Then.. Posted to bios!! A £60 speck of dust later, then it overheated because the pump doesn't work. So, RMA in progress.. Hopefully it hasn't cooked the overclocking potential of the cpu eh? So, video card fans turning on and off? Check the cpu socket for invisible dust.

I do have a spare mechanical hdd so I'll give it a go, but I've tried booting it without any drive in at all and it still has the same behaviour. I just cannot get to the bios screen. I bought a boss speaker and plugged it into the correct socket, and I'm getting no sounds from this speaker at all. (The psu is an 850w platinum evga supernova.) At the moment I have the MB on the motherboard box with the psu, cpu, cooler, ram, and video card. I've tried different combinations to no avail. Now I've disconnected everything and plugged the Cryorig aio pump up to the sata power connector (having disconnected the fans), and the sata cable to the psu. Using the psu tester socket, the psu fan winds up, but I can hear no noise whatsoever from the pump. I even turned the psu into economic mode to stop the fan spinning, and still I couldn't hear a prep out of the pump housing. I figure the pump should at least be working in this instance, even if the pwm fans don't run.. right? Is the pump screwed? I'm tempted to just take the whole lot to a specialist as I just don't have the alternative parts to troubleshoot.

I had a similar issue last week. I bought 3 new Cryorig 120mn fans for the front of the same case. I took 8 screws out from the 2x phanteks 140mm fans. The replacement fans had screws wide enough to screw the fans in from inside the case (ignoring the wobbly long rubber screws), though I had to remove the hd trays to screw the bottom fan in, then put the trays back in. In your "case", I would suggest getting 12 washers if the screws aren't wide enough for the slots. Hope this helps.

Thanks for the reply! Yup, I've done these things more than twice.. How hot should the pump exit pipe get? Unless the mobo or cpu is dead on arrival, I have a hunch the aio cooler pump is busted. I had no idea before tonight, but the outlet pipe temperature is making me suspect the Cryorig. I just hope the cpu is still ok..

Hi there, Please can someone help me? I've just put a new pc build together, but it won't post or Beep. All the fans come on but the video card fans spool up, then down, then up and down again non stop. I've noticed the pipe to the radiator is getting very hot, almost too hot too touch. I don't know if I can hear any pump noise, as I've never heard it before.. I've stripped it back to motherboard, psu, 1x ram stick, cpu and cooler.. Still with no joy. Could the pump in the cooler be screwed? Windows 10 pro 64bit (with intent..) msi x99a sli krait edition (BIOS version unknown.. Haven't got that far yet) Intel i7 5820k (stock speeds) Cryorig a40 ultimate 2x8gb 2400 Kingston hyper X Fury ddr4 Sapphire HD7770 vapor X (also tried with sapphire nitro r9 fury, same outcome) Samsung 950 pro m.2 ssd 256gb evga supernova 850 p2 platinme Enthoo Evolve atx

20-25% increase is significant considering the price increase of 15%. Are there any obvious areas or games where the rx480 would narrow that gap? I've heard the performance gap between fury and 480 may get even wider at higher resolutions, but not realised that much at 1080p? Can the 480 do anything the fury can't? Would the fury be overkill for 1080 gaming? Is it easy to output higher res to the monitor and downfalls these days? I understand I need to get a sweet spot between 45~70 fps for freesync to "activate".. Is that right? Thanks for the 1070 heads up, but I'm intentionally excluding nvidia from this build because I have already bought the freesync monitor (I didn't want to pay the gsync tax). I'm reconsidering crossfire altogether, hence the fury.. Cheers ChrisDiz

Hi there, I'm close to buying a new video card for my first pc build in 2 decades. I've been into computing since 386 days through 486 dx4133, Pentium etc. My first hard disk was 30mb (?!) but it fell out of favour with me when essential discreet graphics costs became prohibitive and I went to consoles.. around our just after the time when half life came out. I played hl2 on a laptop and orange box on ps3.. Now, I've been trying to research what's what, as I'm building an i7 5820k editing / gaming comp. Actually.. It was the mechanical disc optimisation vid from ncix tech tips (with linus' short stroking) I watched when upgrading ps3 hdds, and then watching more LTT and the other techtubers' vids which sucked me back into pc building. I have the build bug. And a shrinking wallet. http://uk.pcpartpicker.com/list/rT8wcc So now, I'm looking at graphics cards. I have a sapphire vaporX hd7770 which I picked up for £30 to get me by until I decide. I was going to get one, then two as money allows, sapphire rx 480 nitro 8gb cards. The sapphire rx480 8gb OC is £256, but my eye has been drawn by the r9 fury (non x) for £300. Between these two, what would people recommend I buy? many thanks, Chrisdiz Ps. I'm not going with Nvidia as an ultrawide freesync was too expensive. Just not doing it. ?
