Re: LSD, a little GA-EP45C-DS3R overclocking help?

You should be able to adjust Vcore higher then that for sure. Can you try a high FSB with the ram all on auto except the above voltage settings? And of course up the vcore

And try with MCH 333 this time around and see if you can get any further, I dont think you Heatsink or PSU is any part of the problem. A double or triple boot is just incorrect settings is all nothing to do with power or heat

Most initial issues with P45 seem to me to be ram settings, then once you finally get them started you can change at will. it is just getting that initial manual settings to go is the hard part

Sure thing. I'll put all RAM settings back to auto except voltage. Mine are rated for 2.0-2.1, so would 2.1 be the safer bet here? Also should I set even the main timings to auto? I'm pretty sure another user with this RAM mentioned running 5-5-5-15 insteasd of 4-4-4-12 in order to OC, but I tried that this last time and it didn't seem to be the cause of my not being able to post with higher Vcore. Should I go straight for 402 fsb or try something smaller first like 366?

And try with MCH 333 this time around and see if you can get any further, I dont think you Heatsink or PSU is any part of the problem. A double or triple boot is just incorrect settings is all nothing to do with power or heat

I kinda figured that it would have to run for more than around 3 seconds for heat to be an issue lol. The PSU and HSF coming from an older build just kinda makes me a little nervous, even though I know they arn't total junk. So which should be more likely to get up and running for MCH, 333 or 400?

Most initial issues with P45 seem to me to be ram settings, then once you finally get them started you can change at will. it is just getting that initial manual settings to go is the hard part

Thankfully there are saved CMOS profiles. Otherwise I doubt I could tolerate this process! Hopefully I will have time tonight to give it another shot.

Sure 2.0-2.1 would be better most likely anyway. 2.2 is HOT on the ram, especially with those paper thin heatsinks. I always recommend to never run 2.2V unless you have a fan Directly on the ram. 2.1-2.2 is just the warrantied amount, generally not what is needed and for sure not at stock speeds

Well it depends on what speeds you want to run the ram at, I would say anything over 850-870 MHZ and 444-12 will fail. That does not mean 555-15 is needed though, sometimes 455-12/15 will work, others 544-12/15 will work.

But yes, for starters when overclocking you may want to set 555-15 or 455-15, and trd of 8 or more.

I would say at 405 or so use 400 MCH latch for sure. Please remember to set this only and reboot and voltages Can be applied as well, then trd and reboot. Then the rest can be done more at once. Set very high twtr and twr for starters as well (twtr -12, twr-14)

Ya, I love F11 and F12, lifesaver!!!

Good luck, and when you post back with or without success please post what settings you are using. And what failed

With these settings, it will not post and reboots itself 3 times or so until it finally posts with last good config. It would still post and boot into windows, even with 402 FSB (but instantly fail Orthos) before I enabled No-Execute Memory Protect under advanced settings and
CPU Clock Skew (ps) to 100 instead of 0 and MCH Clock Skew (ps) to 200 instead of 0 under Advanced Clock Control. When I leave those as they were before so that I can still get it to post, if I set CPU Vcore to any value over 1.20625V the system will not post and will reboot until it reverts to last good config. Having all RAM values set to auto does not seem to help, and anytime I try to push the Vcore past 1.20625V, regardless of other settings, it will not post and go into a reboot cycle. As far as the order in which I have changed things, I do the MCH latch, reboot, FSB, reboot, then Vcore and reboot.

Re: LSD, a little GA-EP45C-DS3R overclocking help?

Ya, Auto is not going to get you in there, have you took some time and tried the first settings on page one I gave you lately. Don't give up, set things timingwise high until you get in there, then you will be able to lower then

[Rooster45]

Re: LSD, a little GA-EP45C-DS3R overclocking help?

OK I'll go back to manually setting the ram. Would it work better if I set one at a time and then reboot, or would it be just as good to do them all at once? Also it still looks like cpu vcore will have to be the last thing I set if I'm going to get anywhere...

[Lsdmeasap]

Re: LSD, a little GA-EP45C-DS3R overclocking help?

Set MCH latch, then reboot, then set tRD And reboot. If your tRD is set Low, like 6 or 7, and you are switching to 400 MCH Latch then raise tRD to 8-9 FIRST. tRD is Static tRead Value, just incase you were not sure

Then you can either set the rest all high, or one at a time.

Over 400 FSB use 400 MCH latch, under use 333.

Set tWR and tWTR very high at first, maybe 12 and 14

And then if you still get no where please post your full settings you tried and I will see if I can help you find out why

Just read this so i havn't had a chance to use it yet. did try some other stuff since my last post though.

I manually set my RAM to 5-5-5-15 (another user with the same sticks mentioned needing to do that to oc) hasn't really helped yet lol.I also enabled No-Execute Memory Protect under advanced settings and CPU Clock Skew (ps) to 100 and MCH Clock Skew (ps) to 200 under Advanced Clock Control. I can still post and boot with those now. I also found that I can boot into windows with my Vcore set higher (tried 1.35 in bios which is about 1.31v according to HWmonitor in windows) if my FSB is stock, but it seems I simply can't do both at the same time (as before I can lower the voltage to 1.2v and get into windows with a FSB of 402 but it isn't stable). Not sure if that helps at all but I figured I'd share my new findings anyway. Seems to me you are fairly certain that the problem lies with the advanced RAM timings and making sure I adjust things just so in the proper order, is that correct?

This thing is killing me I hope we get somewhere soon.

Ya, I think proper timings in the right order will help.

What did you mean by this exactly? >>>

I have been running a mild OC all along, with 333 FSB and cpu vcore 1.20V. This is perfectly stable as far as I can tell, so is generally the point I start from when making adjustments. Also all along I have not even been able to post, regardless of other settings that I had tried until last night, with a higher CPU Vcore. Last night I fiddled around some and set my FSB back to the stock 266 and and was finally able to post and boot into windows with a higher cpu Vcore value of 1.35 in the bios. Once I had booted into windows I verified the the higher Vcore had been set by using the program HWmonitor, which showed that windows saw my Vcore as 1.31V (due to "vdrop"). I was kind of excited until I rebooted to raise FSB again and found that I still could not post with a high FSB (over 266) and a Vcore over around 1.2v at the same time.

Re: LSD, a little GA-EP45C-DS3R overclocking help?

Sounds like you need to adjust some other things as well. Please also use CPU-z for actual voltage values. HWMonitor may be right, but I recently was testing some voltages with this for someone else and we noticed that MANY of the values were off in P45.

So, please post for the the highest set of settings (Full list of settings please) that you have got to boot and I will advise.
