EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

[pdxer]

Messed up the title?

Earlier today I decided to change the clocks to see how far I could push my e8400 at a 1:1 FSB:DRAM divider. I've had my e8400 stable at 4050MHz~vcore1.3750/VTT1.3200 for some time now thanks to this board-Thank you guys very much-, but that was at a 2.4D, 5:6 divider, taking the CPU and memory out of sync.

This is just experimenting to see how far I raise the CPU multiplier with a FSB of 533 and a 1.375vcore that was keeping the 9*450~1.3750vcore/VTT1.320 stable.

So far, I was able to successfully boot and finish this thread with the below settings-

Vcore1.3750. When I raise the multiplier to 7, * 533 = 3731. it boots into W7x64, but I get a device error stating, "device is not attached" and my resolution is at 1280x860. So I count that a non-successful boot! At 6 * 533(Vcore1.3750) = 3200Mhz, it boots fine with above settings. I guess now to check it with LinX and see if it passes 20.

Correct me if I'm wrong, but to have a successful boot at 7*533 I'll need to up the vcore. There are only two or three bumps to 1.4vcore. I want to avoid that high of a voltage because my machine is on a lot. Even though it's on water cooling I just like being cautious.

Here is CPU & sys temps, VID and timings of 6*533-

It took me roughly 20 minutes to write this thread. My temps are still sys 33c, Core0 33c & Core1 33c.

If you have any information to help make this a stable clock, please advise me!


Thanks for reading, off to LinX now.

Leaving VTT auto at such high FSB may not be a good idea, check ET6 voltage tab for target value.
It is very likely you will need to tweak CPU and MCH refernces, quite surprisingly you didn't have to at 450MHz FSB. Is it Prime95 and for how long stable?
Clock skews may also need tweaking, as well as VTT and MCH Core.

Re: EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

P95 14 hours stable till I decided that was long enough! All I do is play games, watch movies and listen to audio.

EDIT: Just failed LinX at 6min, 40sec.

Back to the BIOS board. I'll put my VTT back to within .05 of 1.3750, making the VTT 1.32. I read through a link I was provided from this board that VTT should not go higher than .07 below vcore, and no lower than .05 below vcore.

Going to check ET6.. Brb!

Kind of hard to read, but VTT is 1.6! That's a bit high is it not?

[Chike]

Re: EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

1.6v VTT, you definatly want to lower that, max safe voltage according to intel is 1.45v I think.

[pdxer]

Re: EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

3200MHz, 1:1 settings-

I thought your VTT was supposed to be lower than your Vcore? That VTT is on Auto anyways, so it need to be set.

I set the VTT to 1.32. That's .055 volts less than vcore and got a BSOD on boot. I then tried 1.28VTT and the system would not even post. So I should try 1.3VTT with CPURefv on "Auto" and see if it prompts or boots? ... brb!

[Chike]

Re: EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

Better boot into memtest86+ before you attempt to boot into windows.
You can try higher VTT but most likely that the references have to be tweked.

[pdxer]

Re: EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

While leaving the CPURefv and MCHRefv on 'Auto', I tried VTT 1.28, 1.30 & 1.32. All gave a BSOD on booting into windows.

I can boot and write this post at 6*533 with the above settings(VTT Auto), while doing a bunch of other things(audio, streams of family guy). So how would you tweak the settings? What voltages would you adjust in what direction to try and get the OC stable? System idle at 33c, room temp 21c.

Is it ok to have a VTT higher voltage then the vcore?

And remember, these are my BIOS voltages on Auto, except for Vcore1.3750, MCH1.30, PLL1.57, DRAMv2.2

[Chike]

Re: EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

It's ok to have VTT higher than voltage though it may not be nesessary. Auto set it to 1.6v and that's way too high.
Try adding MCH Core 1.3-1.32v, and more VTT. It is quite a leap from 450 to 533, if you take it with smaller steps even if not 100% stable it may be easier to know what is needed.

Re: EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

check this out for oclocking/benching a water cooled dual on the board type.
Its quite old but still relevant.
early benching

Hi fsb is fine but usually your cpu speed 1,then fsb if the memory can take it ,then memory speed and timings for somewhere between 9-11gb/s memory bandwidth.
Do u have the water cooling running on other component heatsinks?
Ive never used water cooling so ..no experience of settings.
If you dont set vTT and pll they will go very high at high fsb on auto. 1.7v+ and 1.8v+ I seem to remember up around 500(2000fsb)

Thanks Jim, I'll give it a read...

I was asking questions around other boards, people were telling me to raise my VTT and set my vcore to 1.4. Set MCHRefv & CPURefv to .800 to get my 533*6/2131/3200 to even boot.

Well, MCHRefv & CPURefv voltages of .800 did not work. I was getting BSOD from MCHRefv & CPURefv .760 through .800, no matter what VTT voltage used. So I figured I was going the wrong way. Leaving vcore at 1.4, VTT at 1.36 and MCHcore at 1.34. I dropped the MCHRefv & CPURefv to .740 and it prompts and boots. Writing this post now without "Auto" settings on MCHRefv & CPURefv or VTT. Makes me feel like I'm making process!

Re: EP45-UD3Rv1.1(f12) - E8400co/6 - KHX8500D2K2/4G, going

Looking good so far.
The dual core cpu often requires MCH Ref set 1 - 3 clicks lower than the standard 0.760 setting.
Are you using this procedure when setting MCH and/or CPU ref:

1. Set VTT = 1.20
2. Adjust MCH and/or CPU Ref to the desired setting
3. Re-set VTT back to the desired setting

Keep an open mind on the FSB setting, you might find that the best overall performance will be in the 500 - 550MHz range with minor tweaks to the memory timings when using a 1:1 ratio.
