That's unfortunate. Perhaps try the 1000/100 and continue going lower until you find a speed that works? My Dell Precision Workstation 410 maxed out at 850 MHz slot 1's. 1000's booted, but were not reliable. This is perhaps something I should revisit in the future. Maybe the issue was dried out …

It wasn't entirely clear to me how that guy got the copper to stick to the PCB. It sounded to me as if there was a via under the pad and that he was able to get solder melted under the pad, though I'm not entirely sure. I sent the seller of the red MSI card photos of the damage, but he didn't …

I had been wondering if anyone has had success using a SuperMicro P3TDE and Tualatin CPUs without modified Tualatins or without a socket 370 adapter? The P3TDE is a dual socket 370 Pentium III board with AGP Pro, PCI-X, and dual channel PC133 memory. The SuperMicro manual mentions support for …

Cache and processing power on a raid card is used most for parity raid eg 5 or 6. Mirror or stripe isn't very processor intensive and doesn't require much cache. Could there be any performance hit by using 256 MB of RAID cache vs. 64 MB? I can even install as little as 32 MB. The two drives I am …

If you feel like loading Vogons, then 64 MB may be preferred if using Win9x. Vogons seems to load with 32 MB in Win 3.11 w/IE5. I just checked my BIOS. I have SDRAM divisors of 3 and 4. I have it set at 3, so 266.666/3 = 89 MHz for the RAM. I'm also using CL2. THe 89 MHz is probably why I cannot run …

Why do you want to enable NMI? Force IRQs? Or you looking for memory parity checking? I haven't played with this at all. If it is for memory parity, I find on some systems that soft reset can be enough to generate and NMI error. I don't recall what my BIOS options are for memory clock divisions, …

Isn't the main benefit of 15K vs 10K for U320 SCSI due to reduced seek time? I went with 10K U320 SCSI's in this setup because of a) less heat, b) less noise potential, c) less cost. I also recall reading somewhere that later generation 10K drives will outperform earlier generation 15K drives. What …

Yeah, its not bad if you can use a proper PCI 3D card.

The question is largely theoretical. I'm in the process of setting up a two Ultra320, 146 GB hard drives using a PCI-X LSI MegaRAID 320-2 with 256 MB cache. It has two SCSI channels. Is there any theoretical performance benefit in connecting each hard drive to separate channels on the host card, …

So much for my boxed MSI collection. Is there any way to fix this? Maybe strip the pad off a dead AGP board and glue it with a very thin layer of JB Weld or other epoxy?

I managed to find an MSI 8966 6800GT for a decent price. It has a different heatsink though. At any rate, is this red PCB the one which belongs to this box? And does the pure copper heatsink from the dead card belong to the red card? If so, I can swap it and have a boxed item. I'm not sure why the …

I'll let you in on a little secret, the TI 486SXL will run at 2x if you limit the FSB to not greater than 20 MHz. So you can use a 40 MHz crystal and set the SXL into clock double mode. This will give you a 40 MHz upgrade. You can also run a 32 MHz crystal and get a 32 MHz SXL. Not that if you use a …

I did find the spec sheet previously and saw the "Absolute Maximum" Vcore setting of 1.75 V, but it seems like it is awefully high. It wasn't clear if 1.75 V was OK for sustained use. Normally, it seems CPUs have about a 0.1 V, above and below the target voltage for which they can run at. In this …

Most (all?) chipsets cannot be run faster than some threshold. PCB design also takes into consideration operating frequency.
