I cleared the CMOS (following the information in the sticky), loaded optimized defaults, rebooted, loaded these settings, ran memtest, and was rewarded with 42 errors by test 5, there may have been some in test 4, but I wasn't looking at the time.

 

Let me re-iterate what I know thus far:

-The issue exists only when running both sticks

---Individually, both stick work fine

-The memtest issues always occur between 1800 and 2048 in the "Failing Address" column

---This occurs no matter which order the two sticks are in

-It is not a problem with the Power Supply

---I replaced my Rosewill with a more than capable GameXStram 600

-My voltages run higher than set

--- 2.8 setting, 2.92 reported. 2.7 setting, 2.81 reported.

-MANY Bios setting haven't worked

---See previous posts in thread

-Occasionally, I'll get on a good streak, memtest fine, run Windows stable

---These streaks usually only last 3-4 days before things return to failing memtest and bluescreening windows

 

Anything new to try? I'll borrow a DMM from work tomorrow and get my voltages checked out.

Underclock the CPU to the lowest value. (change the CPU ratio).

What happens?

 

Change memory frequency to 333DDR (166Mhz)

What happens.

 

Do you have another CPU to try?

Ok, I've been having a LOT of trouble with the underclocking. To begin with, I started memtesting this morning with the ratio at 4x, which was 803.7mhz. When I came home from work, the power had gone out during the day, and my computer was off. Upon trying to turn it back on, my computer would freeze while initializing, either displaing "Main Processor: AMD Athlon etc..." or the next line, or "Memory Testing: 2096064 ok". The SPD information would not load, and I had to press the reset button at least 25 times to get it to post, at which point it immeadiately crashed in Memtest, displaying only a blue screen with the green Memtest banner in the top left. The plus sign blinked, but nothing happened.

 

I restarted, tried to get into the bios, but it crashed when I selected Genie Bios Settings. I got back in, set it back to normal, restarted, set back down to a 4.0x multiplier, and finally got into Memtest. I let it run for about 2 hours while I did other stuff around the house. When I got back, the timer was "76:09:16," and Memtest had frozen, but the plus sign was still blinking. There were no errors, but the extremely strange passing of 74 hours was enough of an error for me.

 

So, I haven't yet tried underclocking the RAM to 333 mhz, but I figured I'd leave this report for you to muse over.

 

 

EDIT: When setting the DRAM down to 166 mhz, I selected the proper divider, and when my computer booted, the screen displayed that it was indeed DDR333, but Memtest read it as DDR315, operating at 157 mhz. This is with the processor returned to its normal clock, 2210 mhz.

 

EDIT 2: Memtest froze while running at DDR333 (DDR315) and did the same thing. Timer jumped to 29:55:36, and the testing stopped, but the plus sign kept blinking.

RyderOCZ had this to say at the OCZ support forum:

 

Hello,

 

From the description of your problem....the ram does not seem to be the issue here. Each stick works by itself in Slot 2 (farthest orange from CPU) but fails in Slot 4.

 

Also your memory address never changes right? If one of the modules had an issue, the address would change when you swapped slots because addressing is based on the slots, not the modules themselves.

 

Example: (this is assuming that addressing starts with slots 1 & 2, if they are filled) You have 2GB of ram installed...so you have address ranging from 0 to 2048 MB...the Dimm in slot 2 occupies Addresses 0 to 1024 and the Dimm in Slot 4 occupies Addresses 1025 to 2048. Normally when you have a duff module (or actually a duff IC in the module) when you swap slots...the error would change because now that bad IC is in a different place in the addressing scheme. So it sounds to me like Slot 4 has an issue on the board. Have you tried slots 1 and 3?

Do you follow? Did I make sense?

 

Thanks

 

 

Does his analysis make sense? Could the problem be with an IC on the board?
