Hi

Computer spec:
Motherboard: Gigabyte P35-DQ6 (new motherboard)
CPU:E6750 stock speed
Ram: Crucial Ballistix PC2-8500 (2 x 1gb)
(gfx card 8800gts)
(psu 600watt working fine)

I have just bought a new motherboard.

When both sticks of ram are installed in dual channel, games freeze after 5~15 minutes and mem test freezes after 10 seconds (memtest using 2 memtests open using 779 mb of ram each).

>>I have tested each stick of ram separately for 12 hours and have found no errors or freezing.

>>When they are both put in, they freeze in 10 seconds.

The default timings are set at 5-7-7-24 with a speed of 1066 mhz. I tried putting the timings to 5-5-5-15 (factory settings) but memtest still freezes.

I have tried putting them into single channel, freezes still.

I tried to put them at 800 mhz but the machine wouldnt even boot. I used the timings 5-5-5-18, but I couldnt find anywhere in the bios to set my voltage for the ram, so I left the main voltage settings on auto.

Heres the cpu-z action shots :)

So I have tried:
5-7-7-24 @ 1066mhz
5-5-5-15 @ 1066mhz
5-5-5-18 @ 800mhz, couldnt boot, dont know how to manualy set voltages, left them on auto or "normal"

Dont know what to do :( Cant take the motherboard back, I can buy new ram because its cheap, but I want to try and get this working. The ram isnt compatable with the motherboard, but, the crucial ballistix PC2-6400 is, which is essentially my ram but underclocked.

:o

I suppose the next step is to try to get the machine to boot at 800mhz. But I dont know how, or unless you people have any other ideas :)

Thanks.

p.s when it freezes, the screen freezes and the mouse doesnt move, all sounds stop, just a complete freeze with the picture still on screen
 
Your running the right voltage through them? default voltage won't be enough... also you might need to up the voltage to the northbridge +0.1v.
 
CTRL +F1 on as soon as BIOS loads.

Advanced settings should magically appear.

Correct voltage + 2.0 V for 8500 (1066)

;)
 
Ok

But, to do that, I have to set the main voltage controls to Manual.

Then there are 6 voltage controls I need to...control.

The bottom 2 are CPU voltage and Core voltage. Core voltage for 2666mhz should be around 1.21V? And CPU voltage is set on normal, as are all the others. Ill take a photo of it...hold on ill edit this post
 
argh how hard is it to take a picture or something "do you want to format this disk?" No, because I just took a picture with it!! :@@@


Control + F1 does nothing, or it just seems to flicker something. How do I check what voltage my ram is running on?Speedfan says 2.204V on vcore2, but im not sure if thats accurate.

AndyOcUk if the correct voltage for 1066 is 2.0 V, why does CPU-Z say 2.200 on the timings table? I would try 2.0 V if I knew how to change it.

I found a random picture of a bios similar to mine (except the values)

At the moment the system voltage control is set to auto, so I cant change any of those settings. They are all on manual, however, except the bottom one (normal CPU vcore) is on 1.25 V.

Dont know how to set the ram voltage from this...

You don't have to control the 6, you're only looking to change the memory voltage, the rest will stay on their auto values.

Look for "DDR18V" under "PC Health status".

Personally I'd be aiming to put 2.2v through it.
 
Had a problem with my Gigabyte P35C-DS3R board a while back, the memory slots started become defective. Anytime I had two or more sticks of memory in the machine it would BSOD after long periods of usage. The only working solution I could think of until I replaced the board was put in a single 2Gb stick and run in single channel.

It just says 'OK' next to DDR18V...

How does the DDR over voltage setting work? I assume it adds 0.05 V to something.

Hmm, strange. What does Gigabyte's easytune 5 utility say its running at?

Presuming the the memory is defaulting to 1.8v you'd need to up the over voltage setting by +0.4v to get it running at 2.2v.

Have you tried the memory running in the other two slots at all?

Also, it might be worth upping the MCH (NB) voltage a notch or two (although I guess you shouldn't really have to if you're not oc'ing).
 
This is all that it says:

I dont know if that is telling me that the voltage is 2.2, or that its just a setting so I can change it....

Ive tried memory slots 1-3, 2-4, 1-4 (this runs in dual channel for some reason) and 1-2.
 
Going by the pic it seems it's already at 2.2v.

Have you tried upping the MCH (NB) voltage a notch or two?

Other than that I'm freash out of idea's as it seems you've tried everything else.

I guess there's always the possibility that the memory isn't compatible with the board, or the board could be defective.

Hopefully Cob or WJA96 will spot this thread as if anyone can help you further it's them.

GL :)
 
I put 0.025 V to MCH(G) and it still froze.

I also want to know if its the ram causing the problem, and that if buying compatable ram would solve the problem. It just seems silly because the Crucial Ballistix PC2-6400 is supported...:mad:
 
I had the gigabyte p35-ds4 which is almost the same as the DQ6 and had the Crucial Ballistix PC2-8500 ram so the compatability should be fine although two sticks failed a year later.
 
Oh ok, thanks for that, ill keep trying...

He says:

6. These boards have a default VDIMM of 1.8v, set the VDIMM to co-ordinate with your ram. The Geil I have is specced as 2.1v so I have mine set to +0.3v

Im assuming, if the voltage settings are set to manual, and irrelevent of what the gigabyte program says, that the ram is running at 1.8V and I need to add 0.3~0.4V to it.

What would happen if, my ram is actually running at 2.2 V and I put it to 2.6 V?
 
It might die very quickly, I remember that I had to add +0.4v to my memory because it defaulted to 1.8v, I used a program called speedfan 4.33 to to check what the memory voltage was running at to be sure.

I would have thought that your board would be at 1.8v by default unless the memory epp profile voltage was picked up by the motherboard rom. I dont know enough. its annoying how gigabyte don't have the exact voltage selections.
 
Ok I put voltages on manual and added 0.4V

Freezes

I found 2 other threads with my exact problem (after searching for 3 days) and they just bought new ram.

So, I think ill just buy some new ram too then...unless somebody can magically make it work =/

Thanks for all your help :)

Now, does anyone know a good, cheap place to buy some ram? =D *joking*

I probably wont buy any crucial ram, but I think its a good idea to stick with 1066mhz because my modules wont even boot in 800mhz. Its a shame that gigabyte list is to small...

A friend of mine had problems with crucial ballistix series. Can't remember which ones, and which board. He just bought some OCZ dimms and problem solved. :p
 
Maybe a bad motherboard? You say it's new? Do you have another one you can test your other components with?
 
Problem solved:

Bought a new motherboard. Similar one actually GA-EP35-DS3L

Ram run (the original crucial ballistix) overnight and got to 2000% on each 779mb test. (before it got to 2.5% and froze).

Thanks for the help.

ALso, my monitors digital port decided to break with my new motherboard, so that took another 8 hours of fustration XD
