Magic Jump... ???

[SickBoy]

Well, I took the time to move my voltmodded Shuttle AK31A into my main box. Stuck the TBird (1 GHz AXIA-Y) in, slapped on a GlaciatorII HSF and away we went. Win2K didn't like having its motherboard pulled out from under it -thats ok, I'm installing XP tomorrow. Win98 has no problems though.

The mysterious thing, is that I had a 100 MHz jump in capable CPU speed!! I went from no stability at anything faster than 136x10 at 1.83V - no matter how much vcore or VIO I gave it.

Now I am sitting pretty at 1470 (140x10.5) and 2.00V (2.70V DDR voltage). My load/idle temps are not changing much from what they were at when I set the chip directly to 10x133, 1.83v.

Things that have changed since the days of not being able to get past 136x10:

1. Went WinXP back to 98SE (RC1 I guess... tomorrow this HD is getting full version XP Pro)

2. Motherboard swap from voltmodded KT7A-Raid to voltmodded AK31A.

3. Took out my old 13.6 5400 RPM ATA66 drive (which was running XP)

4. Cooler change was from Alpha 8045 to the GII. This I would not think to be a huge difference, both are extremely capable coolers and temps on both are well below the unstable zone (neither have/had hit 45 C)

So what's related, if anything, and what's not? It'd be nice to know for future reference....

My own personal guess is that the OS change was the biggest factor... When I load full version XP tomorrow, we'll see if my overclock holds. (I will be, of course, setting everything back to stock speed whilst I install) I think this baby even has moire left in her... I smell 1.5 GHz ........

On a side note.... my AK31A REALLY dislikes (2) 256 sticks of Crucial at the same time. Win98SE refuses to run like it's supposed to, even when I did the M$ fix (I limited RAM use to 500 MB). I wound up just taking out the second 256 MB stick for now.

Opinions???

Firstly, it's not the first time I've heard of more than one stick of RAM causing OC problems......

A free 100MHz? Good gain!

98 has proven itself to be an excellent OC'ing OS again.

I can't wait to find out what you can squeeze out of that CPU now........:)

The thing is, I'm not sure that it's the second stick of RAM causing OC problems.... it was doing the typical "out of memory" thing that everybody talks about because of Win9X's 512 MB memory limitations. I thought I had fixed it (I used msconfig to set the RAM that Win98 uses to 500 MB) but apparently that didn't work, so I just said screw it for now and took out the second stick.

Well, I am wiping this HDD in a few hours - I am going full NTFS/WinXP, no more of this silly partitioning and dual booting business. 98SE, while apparently being the key to that extra 100 MHz out of my CPU, is still being flaky with me. WinXP RC1 was much more fault tolerant - things didn't start going to the crapper on me when I would try to go for a higher OC. That, and the fact that it won't give me problems with 512 MB of RAM.

On RC1 my lockups were (this is what WinXP told me) related to my Geforce 2 MX driver. I was using Detonator XP's 21.83, but I think it was something OS related with the video driver. The computer would lock at a higher OC, but if I was playing a game or an MP3, the sound would keep going, indicating that it was something video related. I'll see if they fixed this in the release. RC1 WAS just a mite old... (been running it since July :) )

Anyway..... all this experimenting is beginning to get to me. I just want a good solid machine and a good solid overclock. But I am happy to know that this so-called AXIA-Y superchip I picked up is capable of more than my previous setup was allowing it...
