CPU 1 Socket issues

So I run my Z800 with 2 X5690s now. I had boot issues since owning the PC, improper boots resulting in the splash screen never going away, and I would need to boot directly through the BIOS to make it work. I removed a CPU in an effort to increase frame rate in a CPU-intensive game, and my boot issues vanished. This was when I ran X5670s. When I got the X5690s in, I intalled and everything was great, until I restarted the PC. Boot issue again. I visually inspected the socket, but nothing seems out of place... help!

  • Hi,

    Did you check to see if the pin pads under the CPU are clean from any foreign material such as thermal paste? Also, are you running the latest bios for your machine?

      Pin pads are clear, as are the pins themselves. Technically, the latest BIOS is 3.71, but the way I understand it, the latest BIOS isn’t actually supported by the board. You have to download it some really backwards way, and the possibility exists of bricking machine in the process. In addition, I get packet loss issues in-game. I doubt the BIOS would cause that, but I don’t know everything

      If 3.71 isn't supported have you tried downgrading to 3.61A? (I didn't see a 3.71 as a BIOS option on their support site)

      stormson weathers I meant 3.61, my bad. I’m fairly certain that I’m at 3.60

    • stormson weathers I just noticed that the Win8 version will not work with windows 10, but I did find this walkthrough on HP's website.

      Reading this further, I'm guessing these are the steps you mentioned?

I had the Dell Counterpart to your machine, a T5500, but never had to remove one of my CPUs to play games, but the two companies tend to do things outside the PC norm.

      So it wasn’t a necessity, per se. CPU crosstalk was slowing frame rate, I was simply trying to increase speed. So updating the BIOS may help with the packet loss as well?

    • Joe Krol It may and may not, but it's usually a common fix. You can also try and update the drivers for the video card. Also bear in mind depending on what game you're playing;  your video hardware,  RAM, or even the CPUs can bottleneck the game. With that said, it's a matter of what balance you want to get the performance you're looking for. If you want more frames, you lower your resolution and/or disable some unneeded effects, adding more RAM can also help (for example if you have less than 8GB), but it all depends on what hardware you have in your machine aside from the X5690s (You forgot to mention your RAM and video card).

    • stormson weathers I forgot to mention that in multi-CPU systems, its usually best to leave the system in NUMA mode (found in most BIOSes) to avoid CPU to CPU bottlenecks.

      stormson weathers sorry, I’m running a Zotac GTX 1080 8GB and 96GB of normal DDR3 RAM. I’ve never heard of NUMA mode. Is that in the config settings?

      And this link offers some detailed info of the BIOS (F10) settings. From what I can see, there is a NUMA setting in the  "Chipset/Memory" section of the BIOS. There is also other settings that may help with performance.

      stormson weathers you are a scholar and a gentleman, sir.
