250@ 1:1 ok, but no go 275@ 5:4

[Nebulous]

I cannot believe this! I can finally run 250-251 FSB @ 1:1 with 3.25v, but i can't get the 275 @ 5:4 like b4? What the heck?

Tried loose timings, semi loose timmings, raise vcore, lower vdimm, flashed bioses, swapped ram slots, still no dam go :upset: My temps are nice-n-chilly @ 22c idle and 26c loaded H20 cooled. What the hell am i missing here? Keeps locking up at either the welcome screen or when it gets to desktop still loading.:mad:

[Nebulous]

Um...anyone?

[wolfgang]

Do you like the 275 5/4 better?

[skate2snow]

you know 2.6C are the best OCer hey man?

And can you do like 260 5:4?

[Nebulous]

HIya wolfgang, yeah somewhat. I like to switch inbetween.

Skate, I can do 270 5/4, but i was able to do 275, now i can't.

Dam! :shrug:

[thirdeye]

I wish I were stuck with a 2.6c that would "ONLY" do 270...

[Nebulous]

I dunno what the heck it is, but she used to do 275-280 @ 5:4. It's like the vmods did something to prevent it. Evrything is solid as a rock and still i can't get the 275 anymore.

Noticed also @ 250 1:1 evryhting would run smooth as silk, no errors. But the minute i try to run ut2k3 it would crash to desktop.

I'm gettin really fedup with this machine :upset:

[wolfgang]

It takes me 3.4 volts to run 250 2-2-2-5 with my bh-5. l

If you are running high Vdd, have you considerd inadequate NB cooling?

[Nebulous]

The thought has crossed my mind, that's why i ordered one of these (http://www.burnoutpc.com/index.php?page=reviews&review_id=205) :D . Hopefully I'll find out if it's the NB cooling. I have a 40mm delta clone on the NB heatsink now so i'm still puzzled.

Wolfgang, that 250 with 3.4v is rock steady stable? I got my vdimm up to 3.35 and she'll run windows and surf but the minute i try something extensive like gaming she'll crash to desktop.

[wolfgang]

Yeah its stable as a rock I run 2 folders and play games sometimes. I went from 3.2 to 3.4 for stablility. I can squeeze out some more 260 at 3.45 volts. That is a little hard on my psu. This prescott is hogging all the power.

What do your rails look like? thats a lot of vdimm, if you're straining the 3.3v down too low itll hang or reboot..you may need a new PS with rails well over spec with that kind of load..
