1066 vs 800

[bagguns]

I recently bought a new system (Intel E8500, 4gb-800 ram, motherboard: P45 platinum, vid card: HD4870 1gb) and noticed that the memory was only 800mhz. I was wondering if I would see a performance boost with 4gb of 1066 memory instead if the 800? (It is a gaming pc)

No, you won't. Not even if you overclocked the E8500 by a huge amount.
Of course if you ran it @533FSB then you'll have to run RAM @533Mhz (1066DDR) as well obviously, but the performance increase will come from the overclocked processor only.

Don't worry about memory speed. I have tried running single and dual chanel and it makes no difference in games. Even my dual opteron runs better in COD4 with ddr2 400mz ecc ram than 667mz ram. Don't ask me why, it just does.

could be due to timings...other wise, that is strange, might be slighty unstable in some way? otherwise not sure.


you can always put the FSB:ram ratio up a bit if you want to, but the performace incresse would be minamal unless you touch the timings which is more trial and error

In a lowly 1280x1024 environment when gaming, 2-3FPS gain from increased RAM freq. and tightened timing is about the most you can gain depending on the game. Once you go 1680x1050 or higher that difference is completely eliminated. For a dualcore C2D that is.

+1 for NO to DDR2 1066MHz...
Though the performance can increase with a DDR2 800 with CAS 4...

The other thing to remember is that most 800mz ram will run with 1.8 volts. 1066 ram needs 2.2 to 2.3 volts and runs a lot hotter. The thing with my Opteron is quite funny. The 400 cas3 ram improves the minimum framerate a little compared to the 667 cas5. It could also be because it's occupying all eight slots. I'm using a 24" screen at 1920x1200 so the ram latency is probibly more important than ram speed.

I see no point even in tight timing for average clocked RAM freq. The lack of measurable amount of increase let alone noticeable increase (which is absolutely none) at the cost of potential instability just isn't worth it.
And I need it for my Photoshop work anyway.

The exact opposite applies when I'm doing competitive benchmarking with extreme clocks&cooling. This where every score counts and I do whatever to achieve my target including a few dead hardwares in the process unfortunately through excessive voltage.

No.

Using artificial benchmarks, you'll see a bigger number. Using real applications there's no way you'd be able to tell the difference. I'd advise the faster setting only for purposes of stroking your e~Peen.

you only should get 1066, is if your going over 400FSB so its for overclocking mainly

but if your not, than don't save money, same goes for DDR3 mem no need to get the fast stuff as its only for overclocking
