I currently am using Gigabyte M55S-S3 (Rev2.0) and twin 2X2048 - 6400C4 corsair memory. I have 2gb running flawless, recently i bought another 2 sticks but it doesnt work, getting some answers i look at the Gigabyte link page and see that only another version of the corsair memory works. http://corsair.com/configurator/product ... ?id=120129What it shows that the ram is Latency 5-5-5-18-2T As opposed to my 4-4-4-12. So what i am running now isnt possible at all but yet it works, 4 sticks however doesnt work at all. Is it possible to get 4 sticks running at the latency that is described with the ram that is supposed to work with the mainboard or am i destined to buy another mainboard or ram ? _________________ Opera best browser made by mankind!

I suggest this topic: Please post some result ...if successful booting! Ps: you can run cpuz for more info or CrystalCPUID to tweak yours ram (In windows) Quote: Getting to 3.2GHz with the AMD Athlon 64 X2 5000+ Black Edition was trivial. No need to do anything except change the multiplier to 16 - and presto, you have a X2 6400+!
But moving beyond 3.2GHz... now that was a journey.
But in the end, it was a succesful journey. The best stable overclock I was able to achieve was a very pleasing 3.396GHz. This was achieved by running the chip at 12x283MHz, and the memory at 849MHz. All this was done with air cooling.
To get this result:
* manually set the HT speed to 283MHz for both the processor and the chipset
* set the HT multiplier to 4x - again, for both processor and chipset
* leave the Vcore alone, the automatic settings do a great job (or manually set for 1.45V)
* set the DDR voltage to 2.1V
* choose the "DDR667" memory speed setting, this will map to 849MHz with a 283MHz FSB
* set the memory timing to 4-4-4-12
* manually force the "2T" option
I have to say that I was blown away by this overclock. This was the best OC I've ever achieved with an Athlon X2!
Power Consumption
Due to the lower default Vcore, the AMD Athlon 64 X2 5000+ Black Edition required less power than either of the 65nm or 90nm AMD Athlon 64 X2 5000+'s, and the power consumption was still very good when overclocked. _________________  Lan  Wireless

The 4 sticks do boot btw , but windows is crashing hard and the memory test from the suse X64 dvd did result in errors in last 2 sticks.
But i am unsure if the crashing is hardware related (incompatible) or that latency should be adjusted.

Try the last two sticks on their own to rule out hardware issues. After all, if the two new sticks don't even work by themselves, but your two old ones do, then you clearly have a hardware issue. Then, go down to one of the two new sticks to isolate which stick is having problems. In the event that the two new sticks work fine on their own, then that points you in another direction as well. Basic troubleshooting my friend.

It is not about trouble shooting , it is about a hardware incompatibility.
The 2 sticks alone arent supposed to work by themselfs (see Gigabyte link the PDF file will shows you i got the wrong memory).
What i am wondering is that the 4 of them would work with higher latency even instead of using 4-4-4-12 which the ram is rated at i would use 5-5-5-18 which is what the board seems to be able to support for the other corsair stick which is "approved".

If the first two are supposed to work, but do, then why not try and see if the other two will work on their own? I understand that they aren't supposed to work, but does it really hurt to try?

I have two sticks of the same brand of Corsair RAM. What I noticed is that although it says 4-4-4-12 on the sticks; my BIOS detects them as 4-4-4-18.
They'll run at either; but when I stick in another 2 sticks of ram rated at the same 4-4-4-12 values and try them in the stated 'SLI enabled' mode for my Asus Crosshair motherboard; the system POSTS but windows hard locks or bluescreens.
At first it was just my install of Vista that did, and then my WinXP Sp3 install started to. Fiddling with the settings in the BIOS (increasing times, disabling overclocking) allowed it to boot fully.

5-5-5-18 for AMD, only intell can mix match...
