:wave: I have and Intel D875PBZ chipset. For over a year, especially when playing online games, I get a high rate of disconnections. This is after going through 4 ISPs, two different phone grids, complete reinstallation of OS, changing modems, getting the latest BIOS, etc. There seems to be no incompatibility issues of internal comps (they are all high-end brand names), just that randomly the system wants to stop churning tons of I/O data. My CPU core voltage is what I expect after these many months. I require +1.55 volts to be nominal, but several indicators says I am jumping between 1.494 to 1.518. All other voltages read nominal. I checked this chipsets BIOS several times and there seems to be no way to increase this specific voltage. There is only one jumper on the board I can see, it is only BIOS recovery/management related. Regardless if hyperthreading is on/off, same problem occurs (I prefer hyper off). I have contacted Intel but have gotten no reply. Unless there is some way I can increase the CPU core voltage by at least .056 to see if this truely is the reason for instability, then my next solution is to go with another chipset, and you can bet it will not be an Intel. Speaking of getting another chipset, I plan on purchasing one of those ASUS deluxe boards. I use dual SATA drives, with OS/utility programs on one, and games only on the other. Will it cause the OS and harddrives any confusion if I place these filled drives on the new chipset? Furthermore all other components should be compatible, both boards essentially have the same component compatibility. I have lots of great comps, just not what should be a good backbone. Lastly, City of Heroes is one of the online games I constantly play. Another person had a similar issue where CoH had instability until he increased his CPU core voltage. Ostensibly, not enough voltage was being made to crunch that much data. I believe this is what is happening with me, which is why extreme multitasking seems to have issues as well. I do have plenty of ram and such. Thx for your help.
