Single/Double Sided memory issue

[Nikos_abx]

Hello everyone,
i own a CUSL2 with a celeron 366(456). Since now I had a single memory stick , single sided Aim 128 MB PC133 which worked fine on 3-3-3 124FSB (never tried it on 2-2-2 but I didn't care much). I bought yesterday another one, a double sided Huyndai 128 MB PC133 for expansion. I placed the Huyndai double sided on first row and the single sided Aim on second row. Settings : 3-3-3 7T/9T Data driving mode : Normal ( strong also had the same problems) on 124 FSB. And the problems started : Cotinuous hangups, segmentation faults etc on Windows Me. I removed my older one and left only the new one == the system works fine. Result : The sticks don't have problem individually but when they work together. What is the problem ? My motherboard ? The fact that the one is single and the other is double sided ? A BIOS setting ? Please help me on that !

Thanks everyone in advance!

Ãéá óïõ Íéêï,
I have also one single-sided and one double-sided module.The first is a generic 32MB PC100 CAS2 with NEC chips and the second is a Viking 128MB PC133 CAS3 with Hyundai.When they run toghether, at any slots up to 145Mhz 333 7,9 I don`t have problems.Beyond that they start.
Note that NEC can operate stable at 150Mhz and Viking 160 333 7,9 /148 322 7,9/124 222 7,9
Maybe it`s a difference at clock cycle and access time of the chips have(if as you said you`re running at 124Mhz).
Think again of the low mem prices but you won`t get faster with more MB in applications that don`t need much physical memory.If you need speed vs capacity then go for Mushkin rev3(I am going to take mine tomorrow).

Try putting one stick in slot 1 and the second stick in slot 3.

I run two double sided, 128 meg sticks like this at a memory bus speed of 125, mem settings 2-2-2, 5-7.

Rock solid stable.

(Processor is a PIII-600E, OC'd to 1002)

I suggested rev3 because of future change in cpu.
rev 1.5 is fine for 124Mhz(are rated 222 at 133) but I don`t know about Mushkin basic PC133 if can do 222.

PS.Our location is different (ãéá ôçí Viking).

Thanks everyone for the replies, åõ÷áñéóôþ :-)

The reason why I bought the second memory stick is the low price but mainly I am going to work with Oracle which needs memory and I want to have a "comfortable" system. Anyway I arranged a return, I will give back my old Aim PC133 single sided with a Huyndai double-sided , identical with my new one, so I will have two identical sticks on my motherboard. Hope I won't meet any other problems.

if I will , I'll post them here also :-)

Thanks again,
Nikos.

Take raston's advice. I have to run my 2 sticks of 128 double sided in slot 1 & 3. Any other place and I have stability problems in some applications. Weird, but it works.

[Nikos_abx]

Yes it seems very weird, I cannot figure out why this may happen but I'll take your advice though , as you had the same problem with me.

Thanks alot for your help guys!
Nikos.
