OC off after fancontroller install


Recommended Posts

So this is kind of weird.. I have been running my 260fsb stable for around 2 weeks now without a hitch.. Today I get my fancontroller unit and I install that. No ekstra fans or anything, just the controller, and then I hook up my fans to it.

 

To begin with XP wouldn't boot properly, but turned off my monitor just as the "logon as" screen was about to show.. I solved that by booting in vga mode and reinstall graphics driver..

 

Now I can't get my old OC back to stable! My old setting were really easy. Just optimized defaults except for 260FSB and cpu voltage at 1.40.. Stable as a rock..

 

At the same settings now XP bluescreens during startup, but memtest is "stable" (only check with 2 passes so far)..

 

If I go 1.45 on the cpu, XP doesn't bootup at all..

 

At 102% above VID I get into Windows, but it's highly unstable and only lasts for around 1 minute of use..

 

At 104% XP bluescreens during boot..

 

Any ideas? Especially since it was stable before the fancontroller was installed, and no, I tried taking the fancontroller off again, but that has not helped..

Seems somewhat stable at 250FSB (needs more testing - but at least it can complete a Prime95 run) - but where did those 100mhz go? :-S..

 

Memory seems to be fine no matter what I do, but my cpu seems to have a mind of its own today.. I have tried to shoot for some better voltage settings, but 1.40 seems to be the best, even though I can only get 250fsb today..

How is the temps in your computer and inside the work area you're currently location compared to that one time you got a higher clock speed prime stable? Have you tried a longterm CMOS CLEAR?

Just found out 250FSB was not long term stable...

 

Well, it's not warmer here, or in my case.. My cpu dosn't crawl much over 40 ever...

 

The 260FSB had been stable for 2 weeks.. Odd isn't it??

 

Could it be because I'm putting too much load on a single rail? I'm pretty much using the same powercable from my PSU to drive everything.. That is actually the only difference... I had a seperate cable driving 2 120mm fans before..

Definitely wouldn't hurt to move some of those cables around. it's recommended even on the Ultra-D/Sli-DR to give the motherboard one whole power cable from your PSU and just use splitters on the other to power everything else.

Hmmm, I'm sort of stable now at 260*10 x3.0 3-4-3-7 9/10 @ 1.425

 

I'm not doing a full oc thing now as I'm getting my 7900GT in a few days (sig says I have it - but it got delayed), and I'm not into spending 3 days oc'ing a rig that changes in a week. If a fancontroller can mess things up, I have no idea what a graphics card can do :-)

 

Anyways.. From a quick max-cpu and quick max-ram test I got 2700 on the cpu and 260 on the memory..

 

2700 with 9/10 divider didn't complete more than 4 prime95 runs, so now I'm at 2600 with the 9/10 divider.. XP BSOD's on boot without the divider!?!?..

 

Well, if my graphics card shows up before easter, I'll know what I'll be doing during easter :-)

Oddly enough, I'm a wee bit more stable at 300*9 x3 on a 5/6 divider...

 

What is actually most important when it comes to games? High htt or fast memory?

 

I'm wondering if 2600mhz with a 9/10 divider is faster in games than 2700 with a 5/6 divider
