  1. This is a 10yr old thread and what does Obama have to do with netflix???
  2. The internet tells me its a 80mm fan. But you have the computer in hand. Just measure it lol.
  3. Having used many many different pastes over the years I like kryonaut the best. Lowest temps I've seen for sure. MX4 is fine as well. I'm not sure about either of them lasting longer just from normal use. Tons of different types. Some stay wet and messy forever, others will harden up after being heated.
  4. looking at some pictures, the case as a single 80mm fan for exhaust. You will want to replace that as well. I found this thread of someone replacing the stock cooler. No matter the aftermarket cool you pick, you will have to remove the motherboard to install it. https://www.dell.com/community/XPS-Desktops/XPS-8940-Better-cooler/td-p/7690322/page/5 https://www.dell.com/community/XPS-Desktops/XPS-8940-Better-cooler/m-p/7694684
  5. Maybe in a few years you'll find one
  6. Not sure if your trolling but if it is a pre-built it should have a manual, give it a read. Otherwise you need to provide more information. Not really sure what your asking help with.
  7. Ahh. You are your own business. I get it now.
  8. What is your fps without overclocking after hours of gaming? It doesnt make sense why the frame rate would drop to a 3rd of what is it. It seems like a program / driver issue to me with a memory leak. The only other thing I can think of is the GPU is overheating and downclock to keep from damaging itself. But hours into into gaming?? Your cpu might be the one overheating and downclocking. Just some thoughts.
  9. Hmm good point @sticknstone . I,guess I assumed these people already understood CPU overclocking and just trying to get memory stable. But yeah this a 2-part and should be done separately. CPU overclocking and checking for stability is necessary. I use programs like Aida64 and Prime95. Aida64 is less intense, thus is more like encoding temps. Prime95 blasts the cpu to the end of the earth. Thats when a 360mm aio might be nessary. I was getting 33 watts per core. That adds up quick. For memory, it is much easier to leave the cpu at stock unless you vetted the CPU overclock. Put memtest86 on a flash drive and boot to it instead of Windows. Every time you change frequencies or voltages, boot to the flash drive and vaildate your memory settings. If that passes in Windows use aida64 memory stress test. If it doesn't crash the computer you are all set. I do this for every memory review. It takes a few days on and off, but it is the best way to make sure you have soild memory.
  10. Congrats on the free computer!
  11. Before playing around with the CPU, try just the memory. Personally I leave LLC either at the lowest setting or on Auto. I've killed CPUs with high LLC. I hate the function. It should be locked with a warning screen. In any case to get 4400 stable. You will have to raise the memory controler voltage. Auto doesnt always do the job. Start at 4000. Run memtest86 and go up until either you get errors or fails post. Errors in test 1-5 is memory timings / voltage. Test 6-7 fail / system lockup or restart is usually low voltage cpu controller related. Either the voltage needs to go up slightly, or its already been high for a while and needs to cool off. I would avoid going above 1.25v. That should be enough for ddr4 4600. If, you dont want to type in the timings manually, a simple trick is to enable XMP but than change the dram frequency what you want before exiting the BIOS. Also that memory has a second XMP of 4133 I believe. If all else fails, give that a go. I have to tell you guys, from all these memory reviews I've done with lots of hours on benchmarking. 4000 CL15 is better than 4400 CL19. Plus its eaiser on the CPU memory controller. Starting point for 4000-4400 CPU SA: 1.2 CPU IO: 1.15v DRAM: 1.45v
  12. curious what motherboard do you have? I have two sets of that Patriot Viper 4400. On the Gigabyte Z490 Vision G I cannot get ANY memory to put above 4000. Even that Patriot kit is on the QVL.... However using the MSI Z490 Unify I've been able to post at DDR4 4400 without any problems. So the memory doesn't always work at the rated speed, it can depend on the motherboard, CPU and voltage settings. Personally DDR4 4000 CL15 is better I think. Lower voltage and less stress on the CPU memory controller. Much easier to sustain a CPU overclock. I would go for DDR4 4000 first before reaching for the stars. Everyone CPU is different, but you can get similar results. 5Ghz is not uncommon and that guide Braegnok link is a great resource. Here are my settings for 5.1Ghz / 4400. Bumping up the SA and IO voltage is required for higher speed memory. For example, I can reach up 4266 stable with default 1.1v. If its 4 DIMMS I cannot post above 4133 no matter the voltage. CPU VCORE 1.275v CPU SA: 1.2v CPU IO: 1.15v Ring Ratio 43x
  13. I've been looking for the specs saying which CUDA and OpenCL is supported in Divinci Reslolve Encoding. I cannot find it anymore. But it looks like the Free version does not have the GPU acceleration enabled...or so the Blackmagic forums say so. I was using it for Divinci Reslolve 17. But that was the beta, so it might be why it was enabled.

    does this help?
  15. Wow these dual X99 are like $400 on ebay used. I beat you could find a Threadripper 1920X+MB for less. $40 for a pair of 2620 v3 is nice, but not good if all the real brands like ASUS and Supermciro the MBs are all overpriced for something used. If you use Divinci Reslolve 16/17 Adobe Premiere CC21 you do offload the video encoding to the GPU. Much faster then any dual socket CPU system.
  16. Glad to see you back! Question though, why use these old X99 / 2620v3? Other than it being really cheap on ebay, these new Intel and AMDs chips will outperform it easily.
  17. Nah, I gave that up after the last crash. I wouldn't buy a pre-mined card though. Might as well throw the money away.
  18. What is your budget? The used and new market is ridiculous with cryto mining going on.
  19. I would agree. However I do not have any experience with stability testing in Ubuntu. I don't want to suggest possible issues that are unrelated. I have a bunch of stuff laying around so if I am being lazy i'll swap parts left and right. But not everyone has that option.
  20. Well Ubuntu is pretty stable. Is it locking up when under load or idle?
  21. You can go to up 1.35v for 24/7 use. Some big overclockers say 1.4v, but that is a bit high for my own liking for long term use. If you passed a hour long stress test, I think that is enough to consider it stable enough for gaming. I looked it up and the Ryzen 1600 has around a 3.9-4Ghz soft-limit before it takes a lot more voltage and tweaking.
  22. Okay, Since you say thr serial numbers are in order either its 2 kits bought at the same time or more likely actually a quad kit. I was just going by the SKU you listed which only pulls up 2 DIMM kit on google. 4 DIMMs on a dual channel system can have this effect. Depends on the motherboard and CPU. But first I would remove 2 of them and see if you can achieve DDR3 1600. If so there is your answer. If not well it time to dig into the CPU FSB settings and such. Bump some voltages, etc.
  23. I think your problem might be that you have 4 DIMMs. While it usually isnt a issue at lower speeds, having a second set will inherently lower the highest frequency achievable. Not to mention those are sold as 2x4 kit so its possible the other two from the second set are actually completely different ICs which will also cause problems. That's all I can think of. Can't say if that usually is the issue but I would start by removing the second set and seeing you if you can achieve a higher frequency.
  24. The op shouldn't go above 3600 because that is the limit of the 2700X Infinity Fabric. 3800 for Zen2 and 4000~ for Zen3.
