Can you solve this puzzle? (Memory) - Page 2

FSBRAM doesn't matter on AMD at all with the integrated memory controller. In fact, AMD doesn't even use an FSB.

Ive noticed your running you RAM in unganged mode, isnt this the board trying to use 3 sticks in a Dual Channel config?

Try removing a stick and running proper Dual Channel at the rated timings and speed.

First and foremost, almost all RAM has a lifetime warranty through the manufacturer. Contact Corsair and see if they're willing to RMA the memory for you. They might request that you send both sticks in.

Second, you're running 3 sticks of RAM. So I would assume that two sticks are running in dual channel, and the other in single channel. That's not good for performance.

Memory will only run as fast as the slowest stick.

its just the difference in memory chips used in the memory, some chips perform better than others at the same settings.

That's not it guys, probably my fault due to my lack of comunication skills. Let me resume:

1. Two 2 GB corsair sticks model CM2X2048-6400C5 XMS2 2GB PC2-6400 800MHz 240-Pin. 4 GB total RAM.
2. One stick fails. So im with 2 GB of RAM.
3. Have 2 spare sticks of this Corsair Memory: CORSAIR XMS2 2GB ( 2 X 1GB ) PC2-6400 800MHz 240-pin.
4.This two Corsair 1 GB sticks has an EPP, the 2 GB Corsair stick doesnt.
5. System running with these 3 sticks, populating 3 slots 0 - 1 - 2 (0/3). Total system RAM 4 GB.
6. Dirt 2 gets 55 fps in benchmark.
7.Swap the 3 sticks of Corsair memory with this Kingstone memory: Kingston HyperX 4GB Kit (2x2GB Modules) 1066MHz DDR2 (KHX8500D2K2/4G.
8. Dirt 2 benchmark loses 15 fps, running at 800 mhz or running at 1066 mhz.
9.Rest of the games drop between 2-3 frames.

Extract: 3 sticks of unmatched Corsair 800 MHZ DDR2 are kicking the @ss of 2 sticks of Kingstone 1066 memory.

Hope this is a bit more clear.

Well, i pulled the IDE cable of a DVD reader. When i booted the BIOS took longer than usual to upload. Ran the benchmarks and got the frames back with the Kingstone memory. This stuff keeps surprising me.

But... after the next boot the BIOS, again, took a while to upload. Ran the benchmarks and missed the frames again.

So i updated the BIOS to the latest ones and the performance went up. So far so good, hope to keep it that way.

Only downside is that now that everst doesnt report te CPU temps correctly. Seems one cant have it all.

Thanks for all the help guys!

Put the Kingston 1066 memory in the proper slots. As in, the same-coloured slots and not the different-coloured slots. Once you're running dual channel you'll get your performance.
