RAM speed

post #1 of 15
Thread Starter 
Hello OCN.

So I wondered if it is actually possible to run a set of RAM which is made for higher speed than your motherboard is capable of running. Because I seen quite a lot of RAMs sometimes cheaper in a 200 MHz faster version. So would a board that can run 1600 MHz also run 2000 MHz, just only running at 1600 Mhz as long as they're sitting in that MB?

Yes it will,but you have to overclock your cpu to reach the higher ram speeds.Faster ram is sometimes cheaper because the timings are slower.So it's not really much faster.If I were you I would get rid of the 4gb of 667 hz. ram and just use your 800.4gb is plenty.

But as I use 64-bit of Windows won't that slow my PC kinda?

Anyone know if it will slow down or buff my PC when I use 64-bit? Just heard that 4 GB+ is recommended for 64-bit.

it wont slow your PC at all, using 64bit or 32bit will make no performance difference unless the application in question (not windows) actually is coded to utilize 64bit architecture. using less then 4gb of ram in a 64bit OS has no performance hit either unless you are hitting the roof on the amount of ram you have.

i also agree with djsi38t, having the slower ram in your system is forcing the faster ram to run at the slower clock speed as well. so if you don't actually NEED 8gb, i would take out the 667hz, you will see a performance boost when you do that.

Okay so toke out the slow RAMs, but my Windows experience index fell down now lol. Both CPU, memory and GPU score. Only my HDD score of 5.9 maintained old score.

You don't need to worry about that slower ram(If you like to take risks)

There is a neat tool called SPDTool (you'll find it google it)

I made a copy of my ram Spd profile from my 800mhz Kingston DDR2 PC6400 ram and Flash them to my cheaper Samsung PC5300 DDR2 667 ram profile(What can I say? I had a set of PC5300 DDR2 ram and just not using them is not an option, it'll just be wasted money and I'm too cheap to want to purchase another set of 800mhz DDR2 ram)

And I got both set of ram to run at 800mhz =] in fact I even overclocked it at 240FSB speed so all my ram was running at 960mhz DDR2 with 6-6-6-18-24-2T Timings all at its rated 1.8volts

Go read all about it on techpowerup forums(google SPDTool), heck it works and I've ran my Cheap samsung PC5300 ram with the Kingston PC6400 ram flash for a good 2 almost 3 years now and never ran into a problem_

But please do this at your own risk & always Make a backup of the original SPD file on your slower ram just in case you mess up and need to reflash the slower stick back to its orginal clock speeds and timings_

Please Note** During flashing your slower ram sticks with the faster ram sticks profile, the program will go (Not Responding) This is perfectly Normal, just leave it for a good few minutes, it'll say success after it starts responding again_

Crysis 2 seems to take quite a lot of stuff. used 47 % of my 8 GB yesterday. So bet 8 GB would be best to stay with. But this tread was most to know if I could use PC3-10666 or PC3-12800 (or higher maybe) on MSI P67 boards - which only runs at PC3-10600. Because 10600 ones seems to be used by few, and therefor more expensive. But I like MSI's boards as they have good features to a good price

Also would there be a limit on how much higher PC3-XXXXX you can run on a slower board?
