DRAM BIOS Setup Issues: XMP?

[BBorges]

Before you memtest it..... we saw SPD and mem tab...... I'd love to see the CPU tab if you have the time before you commit to mem testing?

Absolutely Allan, here we go:



Now here is a puzzle, i went to CPUz to printscreen the CPU info for you, and i checked the Memory tab for no reason, and the thing is now 666 Mhz. someone is playing a trick on me, ha ha ha.

 A little weird for sure !  you need to get it running stable at any speed to do what Mantis said , and that's run mem test properly over night!.... one stick

 Can you try and forget about /disable XMP completely........... and input the parameters Manually.....all of em!

 I'd go for , try for 9-9-9-27 @ 666 with a touch more at say 1.55/1.60v with one stick in and try to boot to memtest.....and good luck Mr SuLu!

  P.S.....Have you had the CPU out and did this problem set in after that ?

That is correct for a Double Data Rate module that is running at 1333mhz (666*2 = 1333) which is the JEDEC standard speed.

Allan,

I am not sure where the question came from but I have not touched the CPU after the installation on the new board.

Here are the results from MemTest:






What would be the next step? How strict is this test? If needs replacement, should I replace with the same Kingston OR the Crucial memory which lists my mobo?

Thanks guys!

UPDATE

I tried running the system with only the good stick and XMP mode, and the system runs fine at 800Mhz!

I re-run Windows Index and RAM went from 5.9 (533Mhz) to 6.4 (666 Mhz) to 7.0 (800Mhz), and no freeze ups!

I also re-run my Photoshop Benchmark and I got an extra 3.5 secs on the script!!!


This is great, amd I suspect I should only replace the bad stick with a good one and I should be all set, correct? Does that make sense?


Thanks!
BB


PS. I was always under the impression that Dual Channel needed two sticks installed to run, I just realized I can run the system with only one stick installed...

 As bad as this sounds, ... this is a good result!.....Now you know what the problem is!..........Now to address it!

 The good ol days of chucking in any old ram are sadly gone .......in fact memory is usually matched now in double or triple channel kits.

 this is why if it's new Memory, ....you send back what ever was included in the packet (RMA) to the point of purchase for replacement

 Your P.S answer is the system is in fact running in single channel therefore slower then if you had the other stick installed in Dimm slot 2

 Send em both back..... you might loose the PC for a day or two, .... better then getting one stick replaced and finding you're back at where the first post started

Okay guys,

I had received the replacement DRAM only to realize that I had fried the E7500, i guess tweaking the BIOS. Luckily, it was under the warranty. I received today the replacement E7500 (I was running an older Pentium D940 in the meantime).

I am having difficulties setting up the BIOS so that the CPU is optimized and the DRAM is running at XMP. Somehow I suspect the XMP is related to the CPU being used, and though I was able to run the DRAM at 800mHz, I think my CPU does not support it.


Could someone be kind enough to guide me thru the Bios setup for this E7500? I am way over my league here...

This is how it runs with BIOS Optimized settings:


And this is what I have when I try to run at XMP:


I know I am messing up some very basic concepts, regarding Bus speed, FSB, DRAM, and on top of this, I don't know much about XMP. Here are few sticking questions:

1-  How can it be running at 1333mhz FSB if the E7500 only goes to 1066Mhz nominal?
2- How should I set the CPU Host Freq / Clock Ratio and have the XMP mode?
3- How to set the DRAM to run at 800mHz?


Thanks again in advance,
BB

Quick Note:

I am able to foolishly mess around the BIOS, change the Bus speed to 400mhz (      ) and get the DRAM at 800Mhz... but if I do so, the FSB shoots up to 1600Mhz !!  (    ), and the multiplier at 7.0 will give me only 2.8Ghz core speed.

This does not seem right to me, because the E7500 is rated for 1066 Mhz. I would think I should be able to buy new DDR3 XMP and run it at XMP mode without abusing the CPU, or not?

Here is the screenshot:


Is this how things are done or I am missing something here?
