Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

Load BIOS optimized defalts, save reboot, make any changes nesessary like disk boot order, then the following changes in M.I.T:

Code:

Performance Enhance...................: [Standard]
Extreme Memory Profile (X.M.P.).....: [profile 1] <<< or profile 2, whichever youhave and/or is the profile for DDR-1066

MCH Core�����.....1.100V...........: [1.200] <<< try up to 1.26v if needed, sometime less is needed, try 1.05-0.95v

DRAM Voltage ��....1.800V............: [2.100]  <<< try 2.06-2.12v

Please post a screen capture of MemSet main(click >>) and SPD(click spd) windows.

Sorry, I was on my lunch break and didn't get the right info!

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

Are you using the latest versions of Prime95 and CoreTemp?
Your problem might be related to using 8GB of memory.
MCH Core = 1.28 might be needed.

Some systems have stability issues even at stock settings.
Using the recommended settings in this post have fixed problems for many forum members when they have problems at stock settings.

We can best help you if you follow steps 1 - 4 in the post to provide detailed hardware information and the screen-shot in step 4.
Once your system passes extended stability testing, we can help you optimize the performance of your memory.

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

Thanks!!

I'll have that info asap, but I also tested the coretemp sensor test with my old dual core 8400 and got the same error at the same point.

If i have EIST enabled it fails, if I disable it it works. This goes for the dual and quad core, so I think it's a mobo issue rather than the processor.

Thanks again!

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

It might be a bios related issue.
Sometimes the latest & greatest beta bios version isn't!!
You might want to try the most recent "final" bios version.
Setting Legacy USB Storage Detect = Enabled sometimes causes problems when overclocking. This might also be an issue with your current bios version with stock settings.

When you're closing Prime95, has the test stopped and you then manually exit the program?

**xenogear74** · 03-15-2010, 07:49 PM

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

Checking in -

I've run Prime95 & OCCT for extended periods and no freezes! I also have run memtest+ for around 12 passes with no problems. So the only two thing I have questions on now are: 1) I have an issue recently [since my upgrades/bios tweaking-update] where when I restart the computer, I'll get a "hiccup" or reboot loop, and when the computer gets out of said loop my bios has been completely reset? I was thinking this might be a bad battery on the mobo? Or possibly the CMOS is just in need of a good clear? It is very peculiar to say the least. Which leads to 2) here are my updated settings, screen shots, etc... should these be tweaked more to prevent this reboot issue? And if not, considering my specs do things look pretty kosher?

I really appreciate the help prof!

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

The cpu clock ratio is missing from your posted bios settings, I assume that you are using 9.0 x 333MHz.
Set tRFC = 78 and see if your problems persist.

I'm aware that the G.Skill forums suggest MCH Core = 1.40 with 8GB of memory. Most EP45 systems are happy with MCH Core = 1.28 - 1.32, possibly up to 1.36.

When there are multiple boot loops, your system will often try booting where the bios applies "safe" default settings. You should see the lowered cpu and memory speeds during the initial boot screen. If you immediately enter the bios and enter the MIT menu, you will be greeted with a red error message box.

You might need to test with only 4GB of memory (and a lower MCH Core setting) and see if the problems still exist.

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

MCH Core 1.4 is not very kosher.
tRFC 13? This is totally unkosher, not for passover or any other day of the year :-)

**xenogear74** · 03-15-2010, 08:27 PM

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

sorry about that, the ratio is 9*333.

I'll change the memory settings and see if that helps.

haha! what would you recommend for the tRFC? i just pulled that number from the EPP profile? I appreciate your feedback!

And i did get the 1.4 number from the g.skill forums.

**Chike** · 03-15-2010, 08:42 PM

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

tRFC in EPP is 68, tWR is 13, so maybe it's just a mistake in the template? Auto settings would ptobably be fine, maybe 70-72 if not.

Well we are not G.Skill and we do care about your system. MCH Core "absolute max" according to intel is 1.21v, I wonder what would they say over volting their ram to 2.29v. Overvolt may be rquired just no need to over do it.

**profJim** · 03-15-2010, 09:17 PM

Re: Question re: bios settings & RealTemp for EP45-UD3P (1.6)

With 8GB of quality 1066 memory, tRFC set to the pre-programmed 533 SPD setting sometimes is too tight.
tRFC = 78 is probably a bit loose, but it's easy enough to tighten it after the system is stable.

From the G.Skill web page for your memory:

*G.Skill guarantees 2 Dimms Dual channel operation would reach announced specification.

They are one of the few memory vendors that posts this realistic statement.
