Asus P5N-e sli and 4x 1gb ram problem

It's my first post in here, so I would like to say hello to everybody.

Here is my problem:
I bought about 1 mounth ago Scythe Mugen 2 to my cpu, so I had to remove and put back my ram. After that I have problem with my pc. It crashes while watching movie or playing game or copying (usually if more than 5gb's). Before changing cpu cooler, everything works fine.

My config:
Asus P5N-e sli with HR-05
C2D E6420 2.13@3.2 with vcore 1.35 with Mugen 2
2x 1gb Kingston, 2x 1gb Kingmax (800 Mhz) 5-5-5-15 and vmem ~2.1
EVGA GTS 8800 with HR-03
LC POWER 550W (yeah, if you want say it's crappy, you can, but I tryied with diffrent power supply and it didn't help, so it's fine)
2x Seagate 320 and 500 GB's
1x LG ata DVD burner

Temperature is fine, cpu about 35C, gpu 45C, nb 36C.

If somebody help me, I'll be very happy.
Regards,
Patrick.

ps. sorry for my english.

With orthos, prio 10 my cpu temp is about 42C (core temp), gpu temp while playing is about 50C (gpuz says that). Asus ProbeII shows nb temp about 40C. Thermal paste used in cpu is Arctic Silver 5.

No, I don't think it's mobo. I was very careful when I was putting new cooler.

You know, before I put this cooler, everything works fine, I think it's connected with putting this ram in the right order. Because if there is 3gb's of ram, there is everything ok and it doesn't matter in which slot it's putted (I hope you'll understand me ).

Hello Nils, thanks for your post.

1st. No, there is no bluescreen, it just suspend. I can see my desktop or frame from movie/game and I can do nothing. There is no brutall shoutdown and I have to reset pc.

2nd. No, I don't remember how it was inserted before (my bad).

Thanks again.

I didn't notice you were running two different rams. This is more than likely the problem. You probably mixed the channels when you reinstalled it. Be sure each channel (color coded) has the same type of ram. If you still have problems remove 2gb from the second channel, if you still have problems switch to the other kit in that channel. It is never a good idea to mix ram, always try to get an exact match in all channels.

impossible to tell which ram is which from the pic, but you want the same ram in the yellow channels, and the same ram in the black channels. It should be easy for you to tell which is which just by looking at the labels on the Ram.

start with the rated info at the rated speed, and see if you can tweak from there. Like everything with computers, it is hard to recommend settings since each computer will be slightly different.

Nils I'm trying right now that, what belial2k said.
But one dual channel is the yellow and the black slot, not both same colors (I don't know if I wrote it good, I hope you understand me).

I assume in the after picture the other two ram slots have not been filled yet, but he says he is running 4x1gb, so I assume they are now filled....if I am wrong we have found at least part of the problem.

KSKM KSKM or KMKS KMKS would be the proper order....you need to try KS blank KS blank and if that doesn't work try the KM in the same slots...if that still doesn't work reverse the "blanks"....this will weed out bad ram or bad dimms

KSKM KSKM or KMKS KMKS doesn't work... For now KMKS KSKM works fine.

Yes Nils, I'm going to buy new ram, 2x2 1066 Mhz, but I don't know which one for now. But it still make me nervous, what will be when I want to have 4x2Gb's?

Ok, thanks guys for helping me.

I've got last question. Which 2x2 rams would you recommend to me. I'm looking for 1066 MHz.

Small correction. The Corsair modules are a little bit faster than the OCZ ones as they have timings of 5-5-5-15. However you may find the OCZ ram to be cheaper and as they belong to the Platinum series, I'm sure you lower those timings even a bit more.

Can you give a link to the specs page of your shop or the official site? I find it kinda hard to find any info on them.
Anyway, they run @1000mhz, which is a kind of strange speed. Normally you find 533/667/800/1066 mhz for DDR2 modules. I you are using standard FSB bus speeds like 1066/1333/1600 mhz, you might find it harder to get it running @ exactly 1000mhz.

You're welcome
