Upgrade question and timing question


Ned

Recommended Posts

Hi, I have 2 questions so I am not sure if this is the right forum or not. I just bought a new system from cyberpowerpc and had tons of problems with BSOD when playing games. Last night I finally had a crash free gaming experience, I found a lot of good info on http://www.overclock.net and I am now stable. However I would like to time my ram chips to get better performance, right now my bios is on auto. I am not sure what setting to use as I have found some conflicting information so I figured I would get the right information here.

 

Here is what is printed on my Ram (2 Sticks with purple graphics).

 

CM2X1024-6400

XMS6405v5.1

5-5-5-12

800 MHZ

1024MB

XMS2-6400

683875 (on #1) 683876 (on #2) all other numbers are the same on both

07310141-0

 

On other side:

Xtreme Performance

DDR2

Memory

 

 

My motherboard:

ASUS P5N-E SLI 650 SLI LGA775 FSB1333 DDR2

 

CPU:

Intel® Core2 Duo CPU E6750 @ 2.66GHz

 

 

When I put the part number in the support sight here it says the timing should be 5-5-5-15 but it says 5-5-5-12 on the sticks. So I am wondering what the right timing and voltage is.

 

Also the crashing stopped when I moved the ram from the black A2 B2 slots to the yellow A1 B1 slots. If I put more memory in the black slots will I get crashing again? I think I would like to get some more memory and wondering what the best way to get 3 or 4 GB total is. Running 32bit Vista Home Premium. If you are interested in the whole crashing tale look here and here .

 

Thanks,

 

Ned

That was just a mistake and it has been corrected but these modules XM2S-6400 are tested set Cas 5-5-5-12 at 1.9 Volts

 

And if you add more than two modules I would suggest setting the memory frequency at DDR667 as well as set the memory Voltage to 2.0 Volts.

I have stuck with the 2 sticks for the last two years but now I am looking to upgrade. My problems before were mainly solved when I started using the other memory slots so I would like to avoid using all 4 slots. So instead of getting 2 more 1 GB sticks I am going to get rid of those (32bit os) and go with 2 2GB sticks.

 

I have the ASUS P5N-E SLI 650i mobo, I went through the configurator and have these choices:

In stock at Newegg and PC Connection

So the Dominator has fans and costs a bit more but there is a rebate so not too much different. Which one should I get?

Any problems hooking up the fans?

 

Thanks

Should I make a new thread?

Wondering weather to buy

 

TWIN2X4096-6400C4DHX

 

or

 

TWIN2X4096-8500C5DF

 

The second one looks better but I am not sure how the fan works and if PC2-8500 works in my mobo. The first one looks like the safe choice but not as fast.

I ordered these TWIN2X4096-6400C4DHX

I read some more of the threads and figured these were the best for me.

I briefly flirted with the idea of getting the 64bit version of Windows 7 when it comes out and getting 8 GB of Ram instead but after reading the about how you have to go down to 667 mhz with all 4 slots filled I decided to stick with 32 bit OS, take out the 2 1GB sticks I have and go with the 2 2GB sticks at 800 mhz. This pc is 2 years old, should be good for another year and then maybe start over with a new case and mobo for a 64 bit machine.

 

Thanks for the help. I will probably be back checking on my BIOS settings when the Ram arrives though :D:

Put them in yesterday and so far so good.

The closest voltage option I had was 2.085 so I used that. The next one up was 2.17 or maybe 2.2+ I didn't write it down but the one I used was the closest.
