Here's the hardware used when scored.
CPU: Intel Core 2 Duo E8600 3.33GHz @ 4.0GHz (but identifies as 3.33GHz, whereas Windows XP correctly identified the speed when overclocked... so I'm not sure if the score reflects the 3.33GHz or the 4.0GHz, not that it's accurate anyway)
RAM: 8GB (4x2GB) Corsair XMS2 DDR2 800MHz RAM (@800MHz @5-5-5-18)
GPU: MSI GeForce 8800GT 512MB OC
HDD: Western Digital Caviar SE16 (now called the Western Digital Caviar Blue) 640GB SATA
If I remember right, these were my scores on Windows 7 build 7000 x86-64 (i.e., the official Beta).
CPU: 6.7
RAM: 6.7 (with 4GB @800MHz @5-5-5-12, it was 5.9)
GPU Aero Performance: 7.9
GPU Gaming Performance: 5.9
HDD: 5.9
That makes an overall rating of 5.9.
As of updating to Windows 7 build 7100 x86-64 (i.e., the official RC release), these were/are my scores.
CPU: 7.0
RAM: 7.0
GPU Aero Performance: 5.9
GPU Gaming Performance: 5.9
HDD: 5.9
That also makes an overall rating of 5.9.
No doubt the GPU drivers are affecting the Aero score, as certain drivers that don't pass certain something max out at 5.9, or something like that from what I read (that's alot of somethings). I'm using the stock Windows drivers (WDDM 1.1 or something). Still, those same drivers didn't max them out at 5.9 in the previous build...
This is on an x64 build too, but the way.
I can't remember the scores for the CPU @4.5GHz, and no doubt they've changed anyway. Basically, I think the CPU goes up and the RAM goes down. I'll test it tonight perhaps and see.
The official bits about it state anything over 2GB does nothing to improve the score, and that beyond that point, only faster memory speed gets a higher score. That was for Windows Vista though. I saw the opposite happen (in build 7000). With 4GB (@800MHz @5-5-5-12 timings), my RAM was rated lower than my CPU. With 8GB (@800MHz @5-5-5-18 timings), my RAM jumped up to match my CPU. In other words, I added more RAM but lowered the speed, the opposite of what should cause the score to jump, meaning it should have went down, but it went up. Then again, this was the 64-bit build, so maybe it scores more for more RAM like that.
Ah, these scores are honestly not an accurate reflection, and from the way reports are going, not consistent either, so that just makes them useless overall.
Edit: Okay, I tested it again @4.5GHz, and the CPU remained unchanged at 7.0 (the RAM went up to 7.1, probably due to the better timings), but the test took alot shorter and only seemed to test the RAM and hard disk? I'm guessing it only retests what is changed, and since it is always detecting my CPU at 3.33GHz no matter what, it won't retest it. I haven't tried it on stock speed yet, but I did in build 7000, and 3.33GHz and 4.0GHz got the same results there too. Is Windows 7 reporting everyone's overclocked frequency in the "My Computer" properties, or does it not do that anymore? If it's supposed to, it's not for me for some reason. Ah, well, I don't really care about these, or any other synthetic, scores much.
