Am I doing this right? - Screenshots Manual Set Timings

[ghowthoo]

I hope I am doing this right.

I have the G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory.

Unfortauntely my motherboard BIOS doesnt let me change the voltage to my memory. It defaulted to

Memory CLK: 800 Mhz and then memory setting: 400MHz-5.0-6-6-18-2T

http://members.cox.net/ghowthoo/mybios.htm

the 800 MHz and 400MHz kinda throws me off.. I guess one is memory bus speed and the other is memory clock speed... right?

anyway my timings are 5-5-5-15 using 1.8 ~ 2.0 V

so in order to set it in my bios I would need to manually set

TRCD
TRP
TRAS

to 5, 5, and 15? Would I need to set anything else?

Thanks again for the help guys. =)

I think you're better off leaving it as auto because tightening the timing might make your Ram unstable since you can't change vDimm.

aww damn that stinks, do you know the performance difference between the two timings? perhaps if I change the timings the motherboard auto adjusts the voltage with it... I did adjust the timings to 5-5-15 and ran it awhile for 15 minutes but switched it back to Auto so I could consult with you guys before doing it again.

i run on

AMD Athlon X2 3800+ Windsor
Asus M2V Mobo
2gig (2x 1g) G-skill PC2 800 memory
ATI Radeon X1950 PRO 512MB

uh... there's not much of a difference between 5.6.6.1x and 5.5.5.15
You won't notice anything unless you're doing benchmark and stuff. Not a big loss so don't be sad.

No such luck. Check out this post for more info: http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=1249881#1249881

use mem 86 to test the ram in 5.5.5.15 timing. if its error free, then its fine. If it gives you error, then switch back to 5.6.6.18

While memtest86+ (not to be confused with "memtest") is a good test for low-stress conditions, you really need to also test under stressed conditions using something like Orthos before declaring the system stable.

Thanks for the replies guys, I just updated the BIOS and it fixed everything. I didnt have to manually adjust anything. Woohoo!

Well, since we're all here, could you explain the difference? Thanks.

 

[jackluo923]

I think memtest86 + is

a good test for low-stress conditions

and memtest is a program that runs under kubuntu linux or something. There was an option to test your memory when you insert the kubuntu live cd and that program is called memtest.

 

[Mondoman]

They're different programs. memtest86+ does thorough tests including specific bit patterns chosen to maximize detection of any errors, it's currently maintained, it doesn't require an OS, it's free, etc.
There are a number of "memtest" programs out there. I think one is an obsolete (not updated) program similar to memtest86+ and I think another is a Windows program.
When people refer to "memtest" or "memtest86" on this forum, they almost always mean "memtest86+", but it's nice to get the name right so novices don't go off searching for/downloading the wrong thing.
