TCCD Memtest86+ Entry Guideline

[Onepagebook]

** This entry guideline is written by my friend Chonshon.
Testbed：
CPU : K8 S939 3000+
CPU Cooler : XP-120
MB : DFI LANPARTY UT nF4 Ultra-D bios：310-1
RAM : G.SKILL TCCD-LA 440 256MBx2
Power : ZIPPY 500W
VGA : ELSA 6200TC
H.D. : Seagate 160GB 8MB
OS：windows sp1

Get in the bios Dram section first
Set the proper parameters:



Vdimm choose from 2.6v

Enable the memtest86+



Now set the timing of your ram, I set from the most aggressive options:





save bios and leave then system will boot into memtest
we can run the test 5 first
**note: When you run test 5, you need to give your system good air flow. this test product lots of heat.
If you are not aware of this, then the test is not going to be acurate!

press "c" enter to the menu:



then enter 1


press 3 get in to test menu


press 5




enter 0 to start the test you choose


so for the 2.6v apparently is not suitable for this.
************************************************** ***************************************
So now, we will need to back to bios and find the proper Vdimm for that.



get 2.7V：error on the 21st round.


2.8V：error on the 1st round, see, higher voltage is not really useful for TCCD


2.9V：error on the 5th round


From the results above, we can choose the 2.7v for you to test on the DDR600 2.5-3-3-5.

Now we're gonna find the dram drive strength


all the tests above I was using level 5
now we can try level 6~8
level 6


level 7：error until 36th round


level 8: error until 25th


so now, we decide that we can pick the level 7 as dram drive strength

[Onepagebook]

now we will try Tref




3120 cycles


3632 cycles：70 passed no error


3684 cycles


4128 cycles


4196 cycles


4672 cycles


So we see that 3632 cycles with 70 passed no error.

until now, you can just say your Ram only pass half of memtest!
What about the other half? yes, it's test 8#!
In general, I can say, if your setting can get 30 pass error free on test 8, then you are all set for memtest.
(certainly with test5 40 pass error free.)



see here is I got 27 STD passed error free? over 4hours.



Some times your memtest error is not because your ram, that's because yourair flow is not good enough.

Thank you for reading this.

nice guide...

very nice, too bad we dont have a windows version of memtest86+ for those of us who dont have a dfi and rely on A64 Tweaker to adjust these settings.

[Jamo]

great guide, good information as always - good to see you back friend :thumbsup:

Nice Thread OPB and The author, very helpful

[Jackass]

you can have it here

thanks but I have that one I meant one more similar to this one anyhow keep up the good work.

[LowRun]

Thanks a lot for this guide, it'll come in handy when i'll get the missing parts for my rig.

Great guide OPB

excellent guide for TCCD, but keep in mind that passing memtest doesn't necessary mean the windows would be just as stable, in the past I have had memtest on 5 and 8 error free for 24 hours but sometime can't boot into xp, gets random BSOD, or 3dmark failed to bench. Once you're done with memtest there's still a series of tests that are recommended to be run to ensure 100% system stability, such as prime95, superpi 32m, 3dmark in loop and whatnot.

Yes so that's why the topic is "memtest 86+ guide" not memory stable guide!

[Mtemel]

Its thanks to people like OPB and his freind the autor of that guide that make this place worth comming to,

a great help !!!!

Thanks alot for the guide

[chunkylover77]

Good guide OPB. Thanks.

[Necromonger]

Yet, another great guide, thanks, OPB and Chonshon.

[S0nic]

great guide, reminded me that I need to record the results I get instead of going crazy changing numbers all over the place and banging my head against the wall..

[Bennah]

Thanks OPB and your friend Chonshon.

Very helpful information. I havnt used memtest that much... will start to use it to test stability of my new mem when they arrive.

[Nanobot]

Great guide,well done !

Can anyone tell me what the tref 3632 value cycle reads using A64Tweaker ?

I cant find out since my DFI is getting RMA'D and the MSI Neo4 Plat/SLI has different values in bios.

Nice guide

[pershoot]

hey opb. in my environment, for some reason, test #8 takes less voltage then test #5. if i give #5 .1 voltage to pass, test #8 will bomb.

this is with bh5.

any suggestions?

for BH5 play around with Trc, Trfc, Tref, Drive strength, Drive data strength and chipset and LDT voltage - using 310 official or 331-3 beta bios is best for me

[pershoot]

thx i been playing with them and more for weeks, hehe. just cant get a definitive stable mark. either im doing something horribly wrong, or i am just very unlucky.

[TEDY]

great guide !!!

make one for 1A4T=BH-5
