Aaaaccckkk - Microsoft x64 Windows

So I put the system together, configure Intel Matrix Raid, fire up Windows setup and it says: "Aborting, you don't have any disk drives." Silly me, I thought x64 Windows might have driver support for third tier chipset companies --- LIKE INTEL

OK, so I find some drivers on the ASUS CD Rom, fire up Windows Setup, hit F6 saying I've got some drivers, and it says: "Aborting, you don't have a floppy drive." Well, of course not, I haven't used a floppy in 3 years. That 1980 technology has no business being in my computer! You'd think MS could update their 1990 era setup program to find drivers on the Internet or CD-ROM.

LOL but completely sympathetic. This is an example of why every one of my PCs has a floppy drive. I might only use it only once every 3 years but $10 - $12 for a floppy drive is cheap aggravation insurance when it comes to dealing with Microsoft software.

So far so good. Overclocking 25% is torture testing now. Overclocking 30% fails the torture test. This is without increasing voltages (and Vcore is drooping to 1.25V running dual prime).

25% overclock is 3.5GHz per CPU. 7GHz total - yum. Should be much better than the previous measly 2.133 GHz.

Temps are between 56C and 62C with the side panel open (so the floppy drive can hang out the side).

Now it just a balancing act between rock-solid stability / vcore / temps. I'll likely run the FSB at 10MHz below its maximum as determined by torture testing. With a 14x multiplier that is 140MHz below maximum CPU speed.

George, what was it you actually bought eventually? 955x board with an 820 proc?

Anyway sorry to hear of your sata trouble.

Of course Suse 9.3 has support for that chipset and the raiding already in there AFAIK lol.

I'm sure one day you will see the light and move to 64 bit Linux.

Once you get your windows sorted go for dual booting on your new machine which would be a step in the right direction.

Then one day you might grace us with a 64 bit Linux client

Regards,
Peter

I finally selected 3.5 GHz with a 0.0375 volt CPU core voltage bump. This was dual prime torture test stable at 3.6 GHz. Unfortunately, temps occasionally approached 70C with the case closed.

Today, I put 2 80mm fans in 2 5-1/4" drive bays. Motherboard temps dropped 12C and CPU temps 8C. All is good, 3.5GHz, stable, reasonable temps.

Well done George.

I am slightly jealous of your dual 64-bit Intel

Today I carefully fitted a "Gigabyte 3D Galaxy" water cooling system to a 3.4GHz P4 which I have never been able to cool properly from day 1 -- during the hottest part of the summer I had a case fan taped onto the standard heatsink fan, plus a room fan pointing at the open case.

On booting the water cooled system, I looked in bios and the temperature was 23C. I then fiddled with the hidden motherboard feature accessable through "ctrl+F1" and finally settled on the "racing" setting which I'd say was about 3.75GHz -- about 10% speed up on the standard settings. LLR is doing 2.9 msec/iteration at 2.1 million bits

I hope I don't get a leak

I'm very pleased too. This is my third overclocked machine. The previous two times I did not get anywhere close to the results others were getting on the overclocking forums.

Of course, no one posts their crappy overclocking results. So maybe I was getting average results before and I got well above average results this time.

Intel 8xx are made on 90nm process.

For Q1 they migrate to the new 65nm process to make 9xx which will be similar but have also virtualisation.

The process difference should shrink power consumption and heat.

I saw some figures that watts for cpu drop to about 2/3 of the previous levels.

So someone overclocking their 9xx in Q1 should not have so much difficulty with the heat issues.
