Memory upgrade help |
|
|
I was thinking about getting some new RAM. I am currently running 2 gig of PNY pc4200. Will I see a big differance in performance if I go too pc6400? I know its faster but is it worth the upgrade? thanks D.O.A.

you'll see a gain from the added ram, but it will clock down to the lowest speed. generally, you want to run the 4200 anyway, as some systems become unstable with higher speed ram.

I want to replace my pc4200 with pc6400, so it should run @ 800mhz right? My mobo says it will run pc6400 (ASUS P5N-E SLI) I'm just trying to get this system running fast. I didn't see much change between my Intel P4 3.0ghz HT and my Intel core 2 duo e6400 like I thought I would any suggestions would be appreciated D.O.A.
BTW THANKS FOR THE REPLAY 10K

ok, simple clarification.... no, you won't see a gain from the increased clock speed unless you are overclocking your motherboard ALOT.
if running XP it only recognizes 3 gigs. waste of money, imo. put it towards a DX10 card.

To clarify on this a bit more:
1. Not being able to see a full 4 Gigs of RAM isn't limited to XP. Also applies to Vista (Unless you go with the 64bit version).
2. It's not that it only sees 3 Gigs, it actually varies quite a bit based upon your Video card and it's memory. The extra memory you lose, doesn't actually GO AWAY per say, it has to be used to help the memory buffer between your Video Card and your System. Strangely enough, the more memory you have on your Video card, the more memory you'll see vanish from your total RAM. The reason for this is that the data throughput increases the more memory you have on the Video Card, therefore the more of a memory buffer you need between your system and card. From what I read, the 640 Meg cards are only seeing a tad more than 3 gigs, the 256 Meg cards are seeing a little over 3.5 gigs, etc.
Hope that makes sense. Bottom line, go with Vista x64 if you can as this problem is resolved there.

I'm just using the ASUS OC feature have my whole system OCed 20% would I see a difference then?

You will notice a difference with the faster RAM. It may or may not be a day and night difference, but it will be better. Don't mix it with your current RAM or the speed will only be as high as the slower RAM.
I am a big fan of Asus Motherboards. I have had the luxury of trying several speeds and brands of RAM with my systems. I would suggest that you go with two kits of 2 x 512MB Ram ( for a total of 4 sticks of 512MB). Here are the ones that I suggest for your board:
My 1st Choice is Corsair
Model: Corsair 1GB (512MBx2) PC2-6400 DDR2 DIMM Memory Kit
Part #: TWIN2X10246400C4
2nd Choice would be OCZ
Model: OCZ Gold 1GB (2 x 512MB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit
Part #: OCZ2G8001GK
You can pick these up rather cheap. It would be best if you were able to use in another PC or sell your current RAM. Otherwise you are paying for faster and also have money wrapped up in the current RAM. I don't think that is a wise choice. In that case I would save money for a complete system upgrade for the future and be happy with what you currently have.
If you do go with new RAM, make sure you have the latest version of the MB bios prior to installing the new RAM. Sometimes an older bios doesn't support the speeds that the MB advertises. Not always true, but I have seen this a few times. Also use a benchmark of before and after to get a feel for how much the new RAM was different than the old RAM. I would also suggest downloading a free program called CPu-z. It's good for reading where RAM timings are and should be and some other info.

Thanks for the info studdog, I was planning on selling my current ram to a friend. Why do you recommend 4 sticks of 512mb over 2 sticks of 1gig? Just curious

2x1024 pc2 6400 Kingston ram @ newegg $ 88.99 
http://www.newegg.com/Product/Product.aspx?Item=N82E16820134488
and I have no idea why Studdog thinks 4x512 would be better....anytime I or anyone else I know have tried 4 sticks of ram , no matter the density, nothing but problems. More latency ect...

There's no way you should go with 512 sticks. Go with the 1024 sticks and leave yourself room for growth if you sop choose.

I actually wouldn't argue my suggestion, it's just been the best that I have personally seen with several Asus boards. Best benchmarks and most stable from my own experience. Here's some more of why I was thinking that way. It's usually cheaper. When overclocking (as you indicated) you may damage some and it's cheaper to replace a stick of 512MB than 1GB. If one stick fails, it's better to not have all your eggs in one basket. RAM rarely fails, but if it does, a system will run quite nicely on 512MB, where it won't run on 0MB at all. So, to my way of thinking if you want/need 1GB of memory, put in two 512MB sticks whether it's a dual channel MOBO or not." 2GB is the most you can use unless you are using a 64 bit operating system. Like I said it's a suggestion from my own experience, but you can do what ever you want. I was just sharing my opinion, not neccessarily a professional statement. 
Glad you are able to sell the old stuff, that helps. Let us know how it goes with whatever you decide.

That's actually a logical reason for going with 512 sticks I suppose (About being able to run still although crippled if you have RAM issues).
Sorry, didn't think about that.
The only thing I feel that needs correcting is that you mention you can only use 2 gigs of RAM unless you go with a 64bit O.S. (Which everyone should be doing anyways. Time to move forward people). Although it's true that you won't see the full 4Gigs, you will normally see about 3.4 gigs or so for application/O.S. use. This is all explained a bit further in another thread I believe (Or was it in this one further up?).
Oh, I would also argue the memory price comment. RAM is dirt cheap right now. It's a good time to go with 4 gigs right off the bat rather than do it later.

If you want two 1GB or even four 1GB sticks, you might try Corsair: TWIN2X2048-8888C4DF. These are compatible with your MB and would probably be better in the long run considering your 20% system overclocking.
I do agree with using the 64 bit operating system. I tried XP Pro 32 and 64 bit on my current PC. I found the 64 bit to be better.
Here's my current system:
Windows XP PRO 64 bit
Asus P5N32-SLI-SE Deluxe
Pentium 4 3.73 GHz Dual-core Extreme Edition
2 x nVidia GeForce 7900 GTX with 512mb x in SLI
2 Gig (4 x 512) of Corsair DDR2 Pro ram
Two Western Digital Raptor 74 Gig ATA 150 Harddrives in RAID 0
Plus many other goodies.
Here's a link to my system pics:
http://www.uzaclan.net/forums/viewtopic.php?t=5474&highlight=
Again I am not giving a professional opinion, just my own experience with several Asus boards. Here's what happened with my current system: I was able to get the highest average and consistent benchmark scores with four sticks of 512MB. I tried about a dozen different speeds using 1GB sticks and the 512MB sticks. The best I found was actually one set of 1GB sticks of OCZ that was a higher speed than what my motherboard supported. I did not go with it because it would not give a consistent score. The Corsair I went with had a higher average than the OCZ, and hardly varied from test to test. I prefered the consistent scores, I figured it must be a better match or more stable. My tests were done with RAM made to the speed suggestions of my MB and higher speed RAM that was varified to work by the RAM manufacturers. I tried many different settings with the memory. I found that top models of RAM by the Top of the line companies definately was better. Corsair, OCZ, and GeIL were the top ones for me. GeIL was very very stable, but consistently gave me a slightly slower score. These three brands gave me better scores and stable with a larger window of RAM settings. Not sure why, but that was my own experience.
With my other systems I have done tests, but not to the extent of my current system. Again I found OCZ and Corsair to be the best with my Asus MB's. I am only posting this to give you some feed back from my own experiences. I am sure there are people who may know more than me about RAM and will give you better insight, so feel free to not use my input. It won't hurt my feelings any.
