So recently i bough myself a ddr2 533 1gb stick. And put it into my pc. I already have 1gb 533 stick inside and my mobo is www.gigabyte.com/products/product-page.aspx?pid=2466#sp
And whenever i put sticks together pc dosent boot. Both modules are all right and works like new. The slots works fine either. I tryed all possible combinations putting them in and pc dosent boot whenever 2 sticks are inside. I mean they can conflict or something? Please help. Thanks!
 
Solution
Try with the DRAM set to the base timings, and raise DRAM voltage to 1.8, then go to the NB (north bridge) voltage and raise it + 0.07 from it's current setting and give it a try
That's not enough .... are they the same modules ? For example....Corsair Vengeance Pro used Hynix modules up thru version 4.51 IIRC, after that they switched to another brand ....the per 4.51 and post 4.51 don't get along. Also original Dominators at 2400 have CAS timings of 10-12-12-28 .... new ones are 10-12-12-31

Depending on what modules are actually used, they can be difficult..... I once bought two sets of Gskill modules to upgrade 2 different machines Oboth were rated at exact same speed and timings) ..... (one set for each machine) ..... one had Corsair, one has Mushkin. Though the Gskill's would not work in either machine, the Mushkins and Corsair's did. So i put 2 Gskills in one box and the the Corsair / Mushkin in the other.

Not saying it can't work, but the chances are greater the more things that are identical.

Well . The new one is 50-86-86 and idk what the older one is but it says m2oad2g3i4177i1b52
...
Hiw can i fix it if it dosen't fit each other or what should i do?
 
It's extremely old hardware.....finding compatible memory is, as you have seen, going to be quite a chore. Other than trying two identical sticks or dropping speed and / or timings I don't see a solution. perhaps tech support at the memory supplier might be helpful ?

You mentioned i can change timings? How do i do that? Ill place old stick in. Change its timing and place the new one in? Is this possible or am i just dreaming ? About my hardware. I know its ancient and idc about that. I got core 2 duo 2.66ghz and r9 270x . I can do all things like i want to. I just lack some ram... please try to help me out here.

I did it and it worked 20 mins for me. Then pc shat down and didnt turn on after . I pulled out the ram again and now its fine. Then i put it back in and it works fine. ( i think shut down can be due to overclock)
 
Yes, that's oft been my experience with old boxes.

You can set DRAM timings in the BIOS. I always try to get it working 1st at relaxed speeds or timings .... once that passes memtest 86+, I will try doing better w/ higher speed / relaxed timings and perhaps higher voltages.... I have had good success with same module voltage increases but less so when the modules are different. You can usually see what modules you have by looking at the chips themselves .... if you have heat spreaders which don't let you see, they may be mechanically attached (i.e. screws) which you can remove. Glued on spreaders can be a challenge to remove and you may very well damage the modules.
