Intel 1.4 P3-S on Asus TUSL2-C

Edit: Don't bother reading this, I'm a doofus. I wasn't looking at the right stuff.

So I have had this processor overclocked to 1500 Mhz for about 7 months now, but would like to go further.

Here's the thing:

When I go any farther above 1500 it changes the SDRAM frequency to 100 instead of staying at 133. The next step above 1500 lowers the ratios (FSB:SDRAM:PCI) from 133:133:33 to 133:100:33, but these don't appear to be adjustable.

At 1500 the MHz's are 143:143:35.
Anything higher starts off with 144:108:35.

Should I just say f.uck it and keep going, or possibly find a BIOS version that doesn't do this, or even more drastic, try and find a better board that might not do this

Am I missing something?

    I'm not familiar with the TUSL2-C, but on my Gigabyte GA-6OXET mobo there are also some jumpers to control the SDRAM frequency also, besides the settings in bios.

    I just d/l'ed your manual and you should be able to overclock with the jumper block while keeping your SDRAM frequency the same as the fsb frequency. There is a setting for 145/145, 150/150 and 160/160. The 145/145 should definitely be doable and your proc might be able to do 150/150 with your vcore up around 1.65-1.825 v or so.

    According to the manual, you should be able to control the fsb/ram frequencies in bios though, by setting it to manual. Also, I don't know how high your mobo will let you set the vcore; you might have to pin wrap for a higher vcore.

    I've had my P3 1.26S up to around 1615 MHz on air and have had it to 1713MHz with a 120 watt pelt and watercooling, but I run it at around 1500 MHz now as it is my satellite gateway rig to get my folding farm online and I need high reliability out of it.

    Yeah what I did was I decided to do manual settings, as before I was just using the increments it had listed. After changing to manual I was able to force 133:133:33 as the ratio even though it warns not to do that. I have it running just fine at 1550 right now just with air, and vcore at 1.5.

    I only added 50 MHz but thats playing it safe, I spent 200 bucks on this thing, and I don't want it crapping out.

    I'm still not understanding why it was forcing a 100 MHz RAM bus on me.

    I've heard that the TUSL2-C mobo's are some quirky boards; don't know why it might be trying to force the underclocked ram setting in bios.:confused:

    Don't worry too much about hurting that P3S proc; there are some kind of tough. As long as you cool it well, you can run up to 1.825v vcore without problems. I've run mine like that for months at a time and I've had no degredation in stability or overclockability on it at all. The Tualatin's aren't nearly as fragile as the Northwood P4's as far as voltage is concerned.:cool::thumbsup:

    I'm cooling mine with a Kanie Hedgehog and 27 cfm Sunon fan.
