use this utility to compare the memory and spd screens to make sure your ram is being correctly set in bios

often times auto bios settings don't work quite right

No. Try not. Do... or do not. There is no try.

Some people will state that a few memory errors are acceptable - but IMO, none are. I just don't like the idea of an error occurring while I'm balancing my checkbook or performing an online transaction.

those look like the economy corsairs modules

if the spd table says 5-5-5-18 then adjust bios for them to run at that speed, not 5-4-4-18

lower numbers here are faster, cas wait states, waiting higher values are slower but more stable

you might adjust the memory voltage up slightly to help

SPD in the CPU-Z program under SPD I just downloaded is as follows
at a Frequency of 400MHz
5.0-5-5-18
tRC =22
Voltage =1.8V

MB is a Intel D975XBX2
Bios version is 2212
I see there is version update 2792 out there.
Would it be wise to update?

I changed tRCD from 5 to 4 and tRP from 5 to 4 and raised the voltage from 1.84V to 1.96V
Now they match. but it does not match with CPU-Z SPD
When changing tRCD and tRP, I only had the option of 2,3,4,5

you want to try and get the memory tab and the spd tab to match for the cas settings with cpu-z

auto is usually not to be trusted, might be a bios problem?

all this is hit or miss I am afraid, more of an art than a science

I wouldn't push the memory voltage very high tho

At least the longer pipeline intel memory controllers are tolerant of loose ram timings

If memtest passes after adjusting the cas levels you should be good to go, however if it's still glitching then you need to test each module individually in single channel mode

attach png screenshots of both tabs

too bad everest home free is too old for that motherboard

I will give it a try tomorrow, late here in Japan.
This info
A Channel: 5.0-4-4-18 Slot 0
B Channel: 5.0-5-5-18 Slot 0
Is indicated in the Bios, but I cannot change anything,
I was only able to change the tRCD tRP and the like etc.
DeChew, Thanks so much for your assistance.
Also, I played only once since the changes, but Oblivion did not crash on me, I am hopeful

as we say here in America

oh sh1te!

 Fixed calculation and display of the nominal (TCL-TRCD-TRPTRASMin)
memory timing values in BIOS Setup


your bios is beyond old?

 October 21, 2006


there must have been 20 revisions for that board?

I hate to ever suggest a bios flash to people, but in your case I see no way around it

it's the way of the samurai

The bios seems to be a bit outdated. I have XXXXXXXX 2212 and version XXXXXXXXX2792 is the latest as of 9/6/07. Yes there are tons of updates since.
I have the latest version on a USB stick and will do some reading and do the update soon, but we both must agree that if I do it , I do it without the katana(Sword)
I also plan to do memtest when my wife leave the house. I will report results after that
Good Day

It's suggested that you only updated the BIOS in short jumps (2 or 3 revisions at a time), even if it takes several to get up to date. Testing after each one will let you know if the issue is fixed or not - then you can stop updating it.

Just FYI - BIOS flashes are Easy....Easy to do and Easy to mess up. Proceed with care!
1) Triple check to ensure that you have the correct version/file
2) Ensure that there is no way that the flash can be interrupted (kids, cats, power surges, etc)
3) Do not press anything on the keyboard unless you're 100% sure it's the right thing to do. Print the instructions out so you have a reference while the flash is going on - otherwise just sit on your hands while it does it's work.

Good luck!

i booted up today after the changes for the first time
First time My monitor showed nothing so I booted again.
I got to windows and ran oblivion and got the BSOD and it shut down and restarted on its own.
I changed 5.0-4-4-18 back to 5.0-5-5-18 and left the voltage at 1.96V
I am running memtest now and got an error at 655%. Yesterday I had 4 errors in the same amount of time
I am at 830% and just the one error.
I wonder if I bump the voltage just a little bit more say like about .4 Volts that the ram will run better.
Have not yet updated the bios but have the program on my desktop.
