GA-EP45-UD3P - Won't boot with 450FSB

Re: GA-EP45-UD3P - Won't boot with 450FSB

Ok, IBT and OCCT Linpack pass every time now but I am back to OCCT Large failing (Testing Prime Large atm), is it true the latest version(s) of OCCT are buggy and could be causing the failures itself?

EDIT: Prime Large bombed out too, NOW What do I tweak

Re: GA-EP45-UD3P - Won't boot with 450FSB

Is OCCT so different from Prime95 that it is worth testing in both?

Re: GA-EP45-UD3P - Won't boot with 450FSB

Probably not, I just like that OCCT makes a noise when it fails...

Is it like the noise on Family Fortunes when they get an answer wrong? that would be cool. Could change it to that if the sound's customizable.

And our survey said......

I need the big guns to take a look at my template now and see where I could find some Prime Large stability (PLEASE!)...

IBT and OCCT Linpack are passing without error, but standard OCCT and Prime Large are being their usual PITA.

Help!

Not a big gun by any stretch but I'd say (assuming your memory is not the issue here what so ever) that it's one or a combo of #1 CPU VCore/MCH Core/Mch Reference? (could be you never know) #2 Would be *maybe* the chip is at its limit? If that's possible that is.

I know I wouldn't mind running @ 4.530ghz 533x8.5 but I think I'd require a massive VCore to get it stable (I've been trying from 1.36250 to 1.4250 with no luck so far in prime/occt) also looking at your IBT temps, which admittedly would never happen in real world let alone in games are something to think about if I want my chip to last 3-5 years that I plan to keep it.

If Prime large FFT is failing, I'd give VTT and MCH Ref tuning a go. I know you've tuned them already, but not sure if you've done it at this clock speed. Try 0.62-0.76 MCH ref at VTT from 1.2-1.4, you may strike gold somewhere.

Re: GA-EP45-UD3P - Won't boot with 450FSB

Thats 99 combinations psycho (I made a chart!!!)!

[Psycho101]

Re: GA-EP45-UD3P - Won't boot with 450FSB

Yep. It's surprising how many different combinations come from a couple of variables.

You should have seen mt Q8200 spreadsheet when I was trying to go from 3.2Ghz to 3.4Ghz, and stablize the D strap. It would have been quicker to crack 128bit SSL with a BBC Micro.

I see on your latest 4.24GHz( 530x8.0) template that you are using VTerm of 1.32 .
Are you living dangerously.. or has opinion changed that 1.32 is ok? I thought it was nothing over 1.30.

Re: GA-EP45-UD3P - Won't boot with 450FSB

VTT (CPU term) is commonly thought to be safe up to 1.4V. Lower as always is better, but 1.32 is pretty safe, I'd say no riskier than the default of 1.2V really.

Yeah, also PLL being over 1.61 is a chip killer I hear or at least degrades it much faster than it being lower than that.

Re: GA-EP45-UD3P - Won't boot with 450FSB

Agreed. The exact level at which risks increase greatly with PLL, like with VTT aren't certain, but Intel's maximum rated PLL is 1.60V. As UD3 P45's won't set 1.60V, just 1.61, this is deemed acceptable. I will admit I'm comfortable up to 1.65V PLL but will go no higher. That's just a personal choice though, and it may be better to stick to 1.61V.

Wow I've never really played with the CPU PLL. I set it to 1.57 and have left it there.

I am trying the CPU term of 1.32 and now I think I have 4.2Ghz stable.. will know in another 10 hours (or so )

So we should hear something back from you by the end of summer!!
