Stable E8400 OC - stock voltages

Re: Stable E8400 OC - stock voltages

I've been looking for some stable settings and fortunately you listed the same specs I have so I copied your settings and voila! Things seem to work perfectly for me! Most of the other threads I have read on various forums seem to be more focused more on squeezing every last drop of life out of their components while I was looking for something more along these lines. Noticeable performance increase + 0 change in heat = wonderful! I must say everyone has been extremely helpful to a beginner like me, both members and admins. Thanks!

Excellent! Happy to hear this was a success for you!

Re: Stable E8400 OC - stock voltages

You mind if I jump in on this?

Running the same mb (GA EP45-UD3R) with the E8400. Have 4 Gig of OCZ Reaper that runs at 2.2v and is 1100Mhz.

I'm trying to OC at 4Ghz.

• CPU Host Freq = 450
• SMM - 2.00B = 900 (tried 1066)
• RAM Timings = 5/6/6/18 (OCZ specs)
• CPU VCore = 1.3v (lower?)
• MCH Core = 1.25V (tried 1.1, 1.3)
• DRAM Volt = 2.2v (OCZ specs - also current setting)

I've been testing with OCCT. But either the PC locks up, reboots after about 20 min or OCCT reports an error. Always an error on Core #1. Today, not long ago, I got the same error (not sure what all this means) and I'm still working in Windows. OCCT v3.1 through an error that I submitted to MS. Didn't happen with v3.0.

No idea what to do with some of the other adjustments/timings. This board has way more than I've ever seen.

Using the Xigmatek HDT-S1283 along with Tuniq TX-2 .

Re: Stable E8400 OC - stock voltages

Well at 4Ghz you are going to need to set alot more settings then you mentioned. So if they are in Auto then that may be why you are having issues. Vcore 1.3? Ya, I would think maybe

Please post me a link to your ram and then give me the full settings you are using now and I will advise back on where to start

This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

Re: Stable E8400 OC - stock voltages

Please post me a link to your ram and then give me the full settings you are using now and I will advise back on where to start

Here's the link for the RAM. I'm using the recommended settings:

OCZ Technology | Products | End of Life | OCZ DDR2 PC2-9200 Reaper HPC 4GB Edition

I'll get the info you wanted and post it here before long.

By the way my mb is version 1.1 if that matters.

[SBMongoos]

Re: Stable E8400 OC - stock voltages

This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

Just a couple bits of info. First this mb is v1.1 (as mentioned above), secondly the BIOS is F6.

Also, you'll see I've gone with some of your suggestions earlier and adjusted to 3.6Ghz for now until I get the 4Ghz worked out. But the only MIT changes I made were the changes I mentioned before and no other based on info found elsewhere. I could see it wasn't working out so I found this thread and jumped in.

Either way I appreciate your help!

Re: Stable E8400 OC - stock voltages

About your legacy USB Setting, just some tips. You do have to enable that if you ever want to use Qlfash, and just so you know if that is happening with your Fuze, did you after enabling it go into the Advanced BIOS page and set your correct boot orders leaving the Fuze out (First, second, third) and then go into Hard Disk Boot Priority and move the fuze if shown to the bottom of the list. Just letting you know this may be what needs to done to not have that happen. But it may anyway, just giving you some pointers incase you did not know about those settings.

Yes I'm quite familiar with the setting for this. Let me clarify. The PC would do some odd things. Some times have issues booting correctly, other times I'd be in Windows and have some odd behavior if it did boot. I got stuck on that one (laughed after I figured it out). Called Gigabyte and it was the first thing they mentioned to do and the problem went away.

I'll try your settings today.

Re: Stable E8400 OC - stock voltages

You have a few that show ranges (ex: 54-58). Should I start with the lowest and if I have problems move up? How do I know which to bump up since there are a few shown with ranges?

Re: Stable E8400 OC - stock voltages

Sorry for the late reply, since you bumped your thread it got moved to the back end of my reply methods since I start back on new replies and work forward. And I am still trying to catch up (Two Full pages I wont get to tonight alone)

When I posted ranges you should start with the upper range and work your way backward. Not always will the lower, or all the lower, work for you depending on voltages and the other timings.

Did you ever get into trying anything yet? If so and you have issue, post back what you used that failed and I will advise back

Should we start a new thread?

No, have not started yet as I wanted clarification first.

My next question would be since there are a handful, or so, of these options that have variables (start high and work your way down as you said), how do you know where to start. I can set all of those settings at the upper end but how do you know which to start ratcheting down first, etc.? Seems a little random if you're trying to figure out where a problem exists.

I tend to be pretty methodical in my processes and especially if a problem needs to be solved. I've been known to push the limits a bit and take some risks but it helps to have a process that I understand and/or can learn of course.


Thanks again for helping out.

[Lsdmeasap]

Re: Stable E8400 OC - stock voltages

Na, no need to start a new thread at all. I was just letting you know why I had been so late to reply to you was all.

Sorry about that, I just assume people will play around I guess

You would start by lowering tRD (Static tRead) first, then once you have that as low as you can get it, and do not want to push voltages anymore or tweak/try lower voltages anymore to try to get it to it's lowest then you would do the rest in this order >>>

tRRD
tRFC
tWTR
tWR

So start with tRD first. Start with the top setting (3-4, so 4). Idea to get to the lowest setting where the PC/Windows works fine. Correct. Then does this with the next setting and so on. I'm not sure I'm clear as there are various voltage settings in that list to tweak.

Sorry, just being careful. I tend to be rather black and white about some things.

[Lsdmeasap]

Re: Stable E8400 OC - stock voltages

Yeap tRD (Static tRead Value) first. Did you read the memory sticky I posted, it explains what each one is.

Yeap, start with the higher values, then slowely work your way down one at a time. You can test with "If windows will boot" kinda method but after a few I would test with memtest86+ for some quick single test runs as you start to get them all low.

I usually will run memtest86+ test #2 and #5 for about 20 minutes each or so for a quick check once I think I am getting down there. Then after I think I have them all low as can go and still stable I will run 5-10 passes on memtest86+ and then a few hours on test #5

Voltages is a whole other beast, and that can only be found out by you thru trial and error what works and what does not.

MCH Voltage I would set higher until you are done with tRD tweaking as this one is the most finicky, you may find you need a lower voltage to be stable as opposed to a higher one. But the general area would be where you have it now if you know that is already stable

And really until you are done with it all cause you dont want to lower it after tRD tweaking then need to raise it again due to some other setting, or have it low causing you to think some other setting is failing because it is to low when it is really the voltages that are too low

So you want them all really on the higher side until you are set on what you want for settings, then you can try to lower them all a bit starting with Dram voltage, then MCH, then Vtt, then Vcore

Just get in there and start playing around, you can only harm your PC with extreme voltages, something we have not discussed at all here so you will be fine. Incorrect timings will only fail memtest or cause lower benchmarks, you cannot hurt your board or memory with incorrect timings
