Currently have 4GB 1066MHz DDR2, will adding 4GB of 800MHz DDR2 as a boost work?

post #1 of 14
Thread Starter 
Hey guys, so i need to boost my RAM, i did a post earlier asking for advice about my performance issues and the general consensus is that I need more RAM. Yesterday I ordered 4GB(2x2GB) of 800MHz DDR2 memory, I know DDR2 800MHz is not ideal and It costed the same you'd pay for about 12GB of 1600MHz DDR3 RAM as well due to it not being on the market as much anymore.
But I had a thought today that since I've already got 4GB(2x2GB) of 1060MHz RAM, will adding 800MHz as opposed to getting memory with the same latency(1060MHz) not be compatible or hurt my system's performance?

Thanks smile.gif

IIRC if you do that all the sticks will work at 800MHz. Adding more RAM will not improve performance.
If its performance you're after OC your rig. biggrin.gif

Well in this case, my computer is already using a large amount of RAM and when I try to play high memory usage games like BF3, my whole system slows down and the game is really quite unstable and when I'm playing It can get really jittery and laggy because of this, on top of that my computer takes about 4-5 minutes to load up because of all the processes that run on startup.
I explained the issue earlier in a thread and people said that I need more RAM.

it will only run as fast as the slowest....but the 800 you bought may oc up to your existing ram speed

you already have 4 g of ram so adding 4 more will not be a big performance boost...or any boost at all for that matter....it may help in BF3 but as far as everyday performance you will see no difference....like previous poster said...oc your cpu to make it faster smile.gif

just read your last post...in this case then yes it may help you some wink.gif

can you clean up some of the memory hogging programs?

Just make sure they have the same timing/voltages/etc. The 1066mhz with slow down to 800 mhz. And be forewarned mixing ram can cause instability.

I've already been down the road of attempting to OC my cpu, my mobo, or rather my BIOS is unOC'able... My computer just does not work if I attempt to overclock it and I can't be stuffed to update the BIOS. It's not overall performance I want, I'm aware my computer won't become super quick by adding RAM. My issue is how slow my system becomes and how unstable the game is when playing more recently released games that use an extensive amount of memory, like BF3 because my Physical Memory usage is at 86-98% and is becoming stressed and hot.

Man.. I think i'm going to have to cancel this order and get the 1060 MHz RAM that is like 15 bucks more expensive. That'd be fine right since they're the same?

i remember your situation now...yes you need your ram to match or it will all have to be slowed to 800...not enough options in your bios to try to match them


and again you may try cleaning up some programs that auto start that you aren't using...thats a huge amount of your resources being used up!

Yea, I'm going to probably at some point fresh install Windows 7 and start from scratch. It seems that when my RAM usage exceeds 85% while playing BF3 the game starts going a bit jittery, rubberbanding, stuff like that. And if i minimise the game, it will 1/2 the time crash.

If your ram is getting hot to the touch you need to add more air flow to your case or that points at the ram it self.

Also dont forget that your video card will be the biggest limiting factor as it is in my system, because of the vram. Cause higher the resolution and AA used the more vram that will be used up. For example I get the same performance on my card with 512mb ram at 1440x900 with 4x AA as opposed to 1920x1200 with no AA and that is with my vram topping at 500mb with massive hits in citys but game looks horrible without AA to me.

Also read this thread as they got some good info about what Im talking about your vram being your limiting factor. And could possibly shot them a pm to find out, but it looks like the game it self tho can eat up to 4gb of ram easily which is insane I think.
