Yeah, I saw that. That's not exactly what I'm talking about though; that thread talks about whether the memory speed makes a difference in real life, I'm talking about whether the memory divider makes a difference. In other words, does it matter if the memory is "in sync" with the FSB or not; that thread skirts that issue entirely, instead focusing on speed.

Well, the FSB in that thread was fixed, the only variable was the divider unless I'm missing your questions. This is the thread I'm talking about, not the one about different multipliers.

Anyway, there was a slight increases using the faster speed (i.e. asynchronous via a divider), but it required higher MB voltages which produces more heat. To me, the slight gains on the real-world apps weren't worth it. That said, I got much higher gains using synthetic benchmarks. It's your hardware, if the extra heat doesn't bother you, rock out with your cock out, man!

Actually, I was thinking of underclocking my RAM to DDR2-667 (from DDR2-800) to be in sync with the FSB if having them synced would be better than a slightly increased memory speed.

What I am asking about is whether it matters if the RAM is in sync is not, not the speed at all. To really test whether that would make much of a difference, you'd need to test different CPU multipliers but the same resultant frequency, one in sync with the exact same RAM at the same speed and one not, and see if it makes a difference. For instance:

Mem 1: DDR2-533
Mem 2: DDR2-667
CPU 1: E6700 (2.6GHz = 10*266)
CPU 2: E6750 (2.6GHz = 8*333)

Then do a matrix of performance of all 4 combinations thereof. If being in sync matters, then the DDR2-533 should perform better with the E6700, and the DDR2-667 should perform better with the E6750, and the other two combinations should perform worse, at least in memory-sensitive benchmarks and applications. If absolute memory speed matters more than whether it's in sync, then the DDR2-667 should win out in both cases. Obviously if you exteme-overclock the RAM to DDR2-1111 like you did it will win out, but that's not the point; the question is for smaller differences in RAM speed, does running 1:1 confer an advantage over a small bump in the speed but having to use a non-1:1 divider. See where I'm going now?

^ mostly, ull see the differenced in benchmarking programs. not in actual programs. so if u get sync of 1:1 it should be good. but if ur rams are running faster, then ull get more performance (as bechmarking programs say). but little difference in real life applications.

Nice guide.
Instead memtest86 use memtest86+. It's based on memtest86 but it's up to date with hardware.

@burebista - right you are. If you look at my screenshot, it is actually memtest+, I just left the plus off the link by mistake. Added now, thanks.

Guide is now version 1.6

• Added a detailed section to help you find the minimum stable CPU and MB vcore settings. Check it out (near the bottom of the guide entitled, “Stress Testing and Minimizing Your Vcores”)!
• Updated the CPU table
• Provided a less than $5 method you can use to shave off some NB load temps (in the thermal management section at the end of the guide).
