RAM and motherboard problems

Recommended Posts

a while back i posted my problem here and it was semi-resolved but now has popped back up so I am here to figure it out once and for all.. here is the same post i have made at the ABIT forums

 

***Hello everyone and thanks for your time in advance.

 

Here is the issue.

 

within the last 4 months i bought a new MOBO, CPU and HD

abit av8 VIA k8t800p

AMD athlon 4400+x2 CPU

and a WD80gig SATA

 

and from my old system i was using my corsair xms ddr 400 twinx1024-3200xl memory 512x2

 

MY current problem is that with BOTH memory modules installed i get random crashing (BSOD) in graphically intesne 3D games, it is not my video card as it never gets above 60 degrees or so in there. I'ts pretty much just q4 and COD right now

 

windows keeps telling me it has recovered from aserios error and says its from the RAM. I have ran winmem for about an hour on each stick with no errors and it worked fine in my old board.

 

NOW, last night i got the bright idea to check the manual and see if it wanted the memory installed in any specific way and no it does not, then i alternated slots. still crashed.. THEN i removed 1 moduel and tried it and i have had no crasshes or any type of problems for a good 5 or so hours of gaming.

 

I have the memory setup in the BIOS to whatever the specs are(like auto set but i can't remember the name)RPD or SPD

 

So to me it seems the motherboard doesn't like my memory setup but i need to know if i can make it work as i don't have the cash to get new memory right now and technically it SHOULD work fine.. so if anyone can help or if anyone needs more info I will be checking this quite frequently.

 

Oh, i am also going to post a similar message in the corsair message boards

K, since then someone asked about my PSU, and it's an antec 2.0 480

CAS Latency (tCL): 2

RAS to CAS Delay (tRCD): 2

Row Precharge (tRP): 2

Active to Precharge Delay (tRAS): 5

 

Memory Voltage: 2.75 Volts (Warrantied up to, but not over, 2.90 volts) 2.70 ot 2.80 if 2.75 not available

All other settings to defaults.

 

Test one stick at a time IN EACH SLOT using Memtest86+.

K, I made those changes to the setting and i crashed again with both sticks in. so it's not the settings. I don't have a floppy drive right now so I can't test the memory, I will pick one up tomorrow

 

*EDIT*

how long should i run each stick in each slot for?

I would try and set the memory voltage to 2.8 Volts and you should let memtest run one each module one at a time for 2-3 passes to be sure one is not failing. In addition, what PSU do you have and what do you have the command rate set to?

I don't believe i have an option to set mem voltage in the BIOS

 

the PSU is antec 2.0 480w

 

and I don't know what you are referring to about the command rate

 

*EDIT*

more info,

 

CPU external clocl 204/68/34

multiplier x11

agp ration 6:2:1

 

voltages

CPU 1.35v

AGP 1.55v

DDR 2.80v

 

someone in the abit forums pointed out that the memory controller is on chip.. so that brings another part into the problem

ok..tested the 1 stick at a time.

 

the first stick ran about 4 passes i think around 45 minutes and 0, NO errors,

I put in the second stick and boom.. errors were flying all over.. got 111 in 2 and a half passes.. so i guess problem solved.. now I need to send it in to be replaced i guess

 

Ya see the real problem is i had my RAM tested at my local computer store and well they obviously lied to me.. said it passed perfectly fine.. and thats not the case :(

That could very well be the case. Sometimes people just test it by putting it in a machine and running a few programs off it. The deal with that is, if you plan to do that you definately should do it one stick at a time. Reason being you can have one stick work perfectly and the other have errors. If they are plugged in at the same time you might not always get errors.

Got my RAM back, installed with no problems, ran quake4 for about an hour and was very fast, have installed several programs and no problems (before sometimes missing files would show up) and everything seems to be very stable.. thanks everyone :)
