Any ideas?

I have Asus Formula Maximus II mobo with E8500 3.16ghz core2 duo, 4 sticks of Crucial Ballistix 1GB overclocking memory (total 4 gigs)

I called crucial and got new memory sent out, and the new memory has errors in memtest86 just like the old.

This makes me suspect it is a BIOS setting or setup problem.

ANyone have any idea what it could be ?

Here is my set up:

Ask anything you need to know.

Help is much appreaciated!

Reset all BIOS settings to default and try again. If problems persist, it could indicate a memory controller failure (on motherboard) or a flaky PSU.

Ok

Reset now and test....

Thanks

What is the exact Crucial model number of your memory modules?

What memory Voltage are the modules being operated at?

Are you manually setting the memory timings and voltage or did you leave the settings at [Auto]?

The memory modules are two different sets.

My original set was BL12864al1065.8fe5

1066mhz 5-5-5-15 2.2V


I have it in my hand that is what the sticker says.

The 4 sticks in the PC now are newer and a different build.

I believe the Voltage is rated 2.0 on those. I am running 2.02V now.. manually... it seems to run ok but I still get some errors in Memtest86

I can run CPUZ or anything else if you need more info.

I have not adjusted any memory timings (auto mode) pretty much everything in BIOS

If your previous sticks have been replaced there was no reason to post the Part Number of the modules you don't have.

What is the Crucial Part Number for the memory modules that are currently in the motherboard's memory slots?

Can you post the Memory and SPD tab pages from CPU-Z please?

If the memory modules are working correctly you shouldn't see any errors when you run Memtest86+.

The 'reason' any of us need this info is to help you set the RAM properly: DRAM Voltage, IMC Voltage, CAS timings, and to see if the RAM is being mix-matched a/k/a Compatible.

Ok here is the info from the SPD tab of CPU-Z

4 slots full of 1024MB PC2-6400 (400mhz) Crucial Ballistix Memory Part # BL12864AL106A.8FH5

I really appreaciate your guys help with this!!!

Thank you in advance.

If you need a screen shot just give me some info how to load it on this forum.

You can just type the Part-Number in the post.

1. Set-up a free account with -> http://photobucket.com/
2. Click on "Add a reply" {click 6th button in blue}
...or add with no spaces.
...or PhotoBucket has a pop-up for "IMG Code" that copies the code in bold

If you're doing a window screenshot use the ALT + PrtScn and save the image as Jpeg.

Crucial RAM -> http://www.crucial.com/store/listparts.aspx?model=Maxim... there's NO 2.2v RAM listed??!!

BL12864al1065.8fe5 1066mhz 5-5-5-15 2.2V ; CPU E8500

Let's assume the above is indeed correct. The following assumes {NB} there's no OC CPU.

BIOS:
DRAM Frequency -> DDR2-1066MHz
DRAM Timing -> Manual
CAS -> 5
RAS -> 5
RAS P -> 5
RAS A -> 15
DRAM Voltage -> 2.1v~2.4v {increase by +0.1v and test}
Northbridge Voltage -> {Auto ; failure -> 1.3~1.4v}

Hello Mfusick:

Please run CPU-Z and then click on the About tab.

In the Tools group box you will see a command button labeled Save Report (.TXT). Click on it and save the report file.

Post the contents of that report file to this thread by copying the all of the text in the report file and pasting in your reply as code.

If you take a look at the top of the Reply box you will see the Tool Bar with the View more button. Click on it.

A second Tool bar will appear that has a Code button. Click on it.

Open the report file, that was created by CPU-Z, in a text editor like Notepad. Select all of the text and copy it into the Copy/Paste buffer.

Go back to your Reply window and paste the copied report text where the cursor was left blinking when you clicked on the Code button.

Submit your Reply.

The old memory used to be 2.2V ratings... but this new stuff I have in there comes up with 1.8v and 2.0v.

You sure I should 2.2v ???

I am 2.02 now... (not auto)

also I can control the side bus and a bunch of other things...

Should I have it 400mhz or 333mhz?

When 400mhz is selected I can only choose 667mhz or 887mhz (somthing like this)

But when on 333mhz I can choose 1066mhz.


Make sense?

I will go dig up a link to my owners manual...

Question,
On manual mode I can set the FSB voltage...
but I have no clue what to set them all at. Should I leave everything else auto ?

First, no leave everything else alone, the settings I'm adjusting are focused on the RAM and Memory Controller - voltages and timings - period.

Question, when you purchased the RAM did you buy them Individually <or> in Sets of 2?

ok so even though voltage is listed at 2.0v your saying I should be ok to go higher?

jaquith said:
Hence the 'ranges' ===> DRAM Voltage -> 2.1v~2.4v {increase by +0.1v and test}


I am at 2.02 it the system seem to run stable but I do get errors on memtest. Not immediately like before... but I still get them :( 

I think I will bump up to 2.03v and test again, per your advice. Report back the results later.

They were a replacement set ... crucial sent all 4 in two different shipments.

They are all the same build lot as evidenced on the sticker on them.

It's probably the voltage, and RAM typically has a ±0.2~±0.3v operational range. Sure if you want baby step the voltages...but you want it a little higher than barley or just working to compensate for voltage variations. NO just because you set 2.03v the MOBO can vary ±0.05 or more all day; as your CPU's load changes so does the voltages.

I still get errors but fewer... and the pc runs stable now.

Is there a point in voltage I should stop ?

JEDEC states that DDR2 memory modules must be able to withstand up to 2.3 volts before incurring permanent damage (although they may not actually function correctly at that level).
