Bad Corsair memory? say it ain't so! :-(

Hello all,

 

I bought a pair of 1gb memory sticks (TWIN2X2048-6400) for my new motherboard (The infamous ASUS P5B-E). I was getting errors in some games so I ran memtest86 and found I was getting memory errors.

 

So I came to this forum and saw the sticky about this line of motherboards:

 

"Please try and set the tested setting with the Voltage set to 2.1 Volts and Change ‘Write to Precharge delay’ in the BIOS (same page as for latencies) from default 10 to 15. The please disable legacy USB and test with http://www.memtest.org. You can follow the link in my signature for the tested settings for the specific module you have. And all settings not listed should be set to Bios default or Auto!"

 

So I changed these settings, booted back up, and am still getting errors in memtest86. My settings in BIOS are as follows:

 

DRAM Cas Latency: 5

DRAM RAS to CAS Delay: 5

DRAM RAS Precharge: 5

DRAM RAS Activate to Precharge: 12

DRAM Write Recovery Time: 6

DRAM TRFC: 42

DRAM TRRD: 10

Rank Write to Read Delay: 10

Read to Precharge Delay: 10

Write to Precharge Delay: 15

 

And the specifics of my memory are:

CM2X1024-6400

5-5-5-12

800 Mhz

XMS 6405v5.1

 

Also, something weird I noticed in Memtest86, it seemed like only the last bit in each failed memory address was the one that would fail. For example, it would write 08080808 to the address and then read 08080800. I got about 30ish failed memory addresses this way.

 

So do I actually have bum Corsair memory? so weird, cause Corsair is the best! Also, if I RMA this memory, is there any way to get some cross shipped so I won't be without a computer for a week?

 

Thanks!

When you tested them with http://www.memtest.org, did you have Legacy USB disabled?

 

Yes, Legacy USB is disabled and voltage was raised to 2.1 volts.

 

Also, I've run memtest86 a few more times, it keeps coming up with the same thing, whatever sequence it runs, its always the last bit in the byte that is the bad one... bfbfbfbf gets read as bfbfbfb_ (_ is something other than f).

Yes, one of my CMX512-3200C2PT sticks from my 1gig Platinum Series has

failed. It was checked by me and one of my pro geek friends. This is one of the

three Corsair Dual Channel kits I use in my computer builds. The other two is

my old standby 1gig Value Select 3200, and my new 2gig XMS DDR2 6400 kit.

As far as this old geek is concerned, Corsair is the best memory out there. If I

can get a number from the Ram Guy, I'll be able to complete the RMA request,

get it replaced, and then come back to learn from all you young wipper-snappers. Who says you can't teach an old geek some new tricks? I

learn something new about this wacky hobby everyday from someone younger

than me. senior geek

Senior Geek, I think you may have wanted "New Post" not "Reply" :laughing:
