Water-cooled 865PE + Radeon 9800 XT = rocketship . . . pulls a Challenger
The good news: even without any overclocking, this new rig is yielding
90 to 100fps at 1600x1200x32bpp with 3D programs! The bad news: after a few minutes or hours, it suddenly produces a strange, Herringbone pattern of garbage on the screen. When the pattern comes up, the keyboard and mouse still work, so I can exit WinXP by pushing the Start keyboard button, then "U", and "U" again. So I'm thinking it's not the CPU or the memory. The only "symptom" I'm getting from CoreCenter is that from time to time, the alarm will go off because the 12V rail dips into the 10.5V range. The alarms have no correlation to the appearance of the garbage screens. Even if I thought the 12V rail was causing a problem, I don't see any way to control it via CoreCenter or the BIOS, so I'm not sure there's anything I can do about that. Please look over my config and give me some suggestions for fixes. THANK YOU in advance! HARDWA MSI 865PE Neo2-FIS2R w/default "safe" BIOS settings (I tried OCing just for kicks and it made matters worse: BSOD, a boot-up error that says "DRAM timing is too tightly . . ." etc.) Asetek WaterChill system with CPU and Northbridge cooling blocks (temps in Centigrade are in the low 40's idle, high 40's at load) P4 2.8GHz w/800MHz FSB (shows up as two CPUs in Device Manager, so I know Hyper Threading is working) 1GB Corsair Platinum RAM (2x512 in slots 1 and 3 for 800MHz) Radeon 9800 XT w/256MB RAM (interestingly, the fan on this card is very quiet. I fully expected to buy a water block for this GPU, but the fan is so quiet I think I'm going to leave it as-is.) PS: ThermalTake 480W Silent PurePower Two 200GB Western Digital SATA drives configured as RAID1 on the Promise controller (these are MUCH quieter than my old IBM 60GB RAID1 drives) BIOS SETTINGS (v1.7): Hyperthreading: Enabled DRAM Timing by SPD: Enabled DRAM Timing: 2.5, 4, 4, 8, 8 AGP aperatu 128MB Spread Spectrum: Enabled Dynamic OC'ing: Private Performance mode: Slow DRAM Frequency: Auto CPU Bus clock: 200MHz DDR clock: 400MHz DRIVERS: Intel 865: v.5.0.2.1002 Radeon 9800 XT: 6.14.10.6387 Thanks for your help!

Even though the TT PSU has great specs, that 12v fluctuation is not a good sign of stability. Also, the herringbone sounds like it could be overheated or overstressed video memory. In a water-cooled system, sometimes people forget that ventilation is still necessary to allow the remaining air-cooled components to work properly. Not saying that's your problem, but if the card is overclocked or it's in a hot air pocket, it's worth checking. |

Ben Sounds like the video card is getting too hot. If you're OC'ing it, back it off a little. |

I had a brand new 9800 that produced a weird herringbone pattern before it got to the post screen, sounds like a video card issue to me.. I'd RMA it. -- Stacey |
