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

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

Unfortunately not. I hooked mine both up to a 4 pin molex adapter each. I don't use the BIOS PWM/Voltage control, I use the CPU header to be able to control my Yate Loon GFX fan with Speedfan.

I found the Fan header specs on this UD3P to be the worst thing about the board. What's needed is 4 PWM headers, all outputing a max of 12V. The 5V header is a complete waste of time IMO.

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

Ok I seem to keep failing to OC around 18-20 hours... so I decided to make sure my basics are working. I went with just a 500FSB with a 3Ghz cpu... an underclock of the CPU actually. Last night I failed with a MCH of 1.260. Maybe I should take my advanced memory setting and just make them ultra loose instead of auto.

This is what I am trying now.

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

A 500 FSB wants a higher MCH Core than 1.26. Try raising it one notch at a time. Also, I think I had to lower my MCH Ref a notch or two...

[D-an-W]

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

Just to echo what grishkafool said, my latest (510x8)...

Passed so far, 20x trials IBT, 20hrs Prime Small & 22hrs Prime Large (Will switch to Prime Blend @ 24hrs).

[D-an-W]

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

72hrs of Prime (& Other stuff) later I am pretty confident 510 x8 is stable.

520 x8 is proving harder though to even get to boot, sometimes it just leaves me with a _ in the top left of the screen after POST. If it does boot it locks up once IBT is set to Gas mark 10...

I guess it's going to take more than a lift in MCH Core to sort this one

[Psycho101]

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

I can get hold of a depleated Uranium cooling rod... that might help...... Kidding

I'm confident you have the knowledge to get it to boot if it's possible. I have noticed though that you still have CPU Term on 1.200V. This is good that you've got that far with it on default, but you may need to try raising it. Use al combinations up to 1.4V then try lowering MCH Ref to 0.720 @ 1.2VTT and try 1.22-1.4VTT again.

Good luck!

I know i have a quad so it might be different but my cpu doesn't like more then 1.36V FSB and less the 1.3V for 500+ FSB. And i tried right up to 1.45V. It takes time but you start to see what your cpu does and doesn't like

Great work so far

[Psycho101]

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

I agree. Usually at least a small bump in VTT is needed, but how much depends on the CPU, the Vcore used and the GTL Refs (CPU and MCH) used.

[profJim]

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

Increasing tRD (Static tRead Value) is probably needed above the 510MHz range.
D-an-W has been using tRD = 9 for quite a while.
It will be interesting to see what the 520/1040 cpu/memory speeds will do to the Everest memory/cache benchmarks with looser memory settings.

[D-an-W]

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

Tried a few suggestions last night without any success, I will have more time over the weekend to test further.

It's quite frustrating but I remember once not being able to boot at 450FSB

[jonathankru]

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

Try more vcore. It seems like when i use 1:1 strap i have to give cpu a little more vcore to stabilize.
It helped me do the following

[D-an-W]

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

All efforts failing so far, I hit a similar wall at 480FSB but MCH Core sorted that one out and has been the key to getting 510FSB stable.

The best I can get to pass IBT so far is 513FSB, have any other E8400 owners come across a similar issue?

[grishkafool]

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

As FSB goes up, MCH Core needs to rise. At some point, for me, though, some where around 505FSB, MCH Ref needs to lower a tic as MCH Core goes up.

As CPU Multi goes up, vCore needs to rise. As vCore rises, vTerm needs to rise with it, but not at the same rate. As vTerm rises, MCH Ref rises...

It seems like I get my stability when there is a harmony involving vTerm and MCH Ref. I find stability when MCH Ref stays near or under .808v, in relationship to vTerm.

Can't stress how important this THREAD is.

[D-an-W]

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

Progress @ 520FSB x8!

Working backwards using a 500x9 template I have tested, 20x trials of IBT have just completed without error (Will post template shortly)...

Try the skew! Our motherboard is not limited to a mere 510 FSB.. people get to 600FSB on it.

Try like a 250-400 cpu skew. I think the CPU skew is for FSB overclocks, and the MCH skew is for massive CPU overclocks, from what I am reading.

**EDIT** I was wrong.. I am using a CPU skew of 350 and a MCH skew of 200 for a 515FSB x8 = 4.12Ghz. The CPU skew is for CPU increases and MCH is for FSB increases.
** EDIT**

I've been away for a week on work.. so I've good no updates of my own.
