|
 |
First of all I`d like to know whether upgrading my RAM from 2GB to 4GB would have a noticeable effect on performance @ 1920x1080. Secondly, how much of that 4GB would go unutilized in a 32bit Windows 7. Finally, I gathered from the big hardware post that brand and cost don`t really matter much when it comes to RAM, so would this: http://atf.ee/arvutikomponendid/malud/apacer_ddr2_pc6400_800mhz_2gb_au02ge800c6nbgc/ work allright with a Asus P5B-Plus Vista Edition mobo.

Glad to see someone using my hardware post!
Of that 4 GB, 1 GB would be unusable leaving you with 3. You probably would notice it, although it depends on the game and how you use your computer.
Brand indeed doesn't matter that much, although A-brands tend to cause less problems; I also recommend to use two identical chips, going for 2x2GB. What do you have now?
Check the QVL for your motherboard to see what's been tested to work, and get 4GB of those chips. I couldn't find a P5B Plus Vista Edition, so I'm assuming you meant the P5B Premium Vista Edition, the QVL for that can be found here: http://dlsvr.asus.com/pub/ASUS/mb/socket775/P5B%20Premium/P5B_Premium_Vista_Edition.pdf
Looking at the list, it seems no 2GB modules have been tested, so your best bet would be to get one of the Kingston 2x1GB kits I reckon, but 2GB might work just fine, QVL's are never complete. All depends on what you have now though!

That's not entirely true.
3.2gb will be used be available to the OS.
There will be 819mb of the 4gb unused in a 32bit system.
The gains will be clearly visable to you but not 100% of the time.

Right now I have 2 sticks of A-Data 1GB 800MHz DDR2. Would be a shame if I cant use them. Would a 2GB A-Data stick be similar enough to avoid conflicts? Oh and I do have a P5B-Plus Vista Edition mobo. Here`s a pic of its box I found on the net:  Spoiler: | |

Strange, can't even find that on ASUS' website o_O
Anyway, what I meant was getting 2x1GB instead of 1x2GB, doesn't have to be the same as your current set. Your motherboard has 4 DIMM slots right? So you've now used 2, just use the other 2 for the other 2 GB. You're not gonna go beyond 4GB anyway, and even if you were, you wouldn't do it with this board 
Bigger chips aren't better (or worse for that matter), and by using 2x1GB you get the benefit of dual channel on that pair as well. Again, not something you'll notice straight away, but when using memory intensive stuff (Photoshop is an easy example) it does help a little.
@ Slizza: I know that, you know that, but most people don't give a shit as Windows reports 3GB, and it's close enough for those

You can mix the sticks up. performance usually goes with the speed of the slowest stick.
You will lose dual channel mode and likely there will be a further slight performance hit from the mismatched sticks.
It should still be faster overall than just running the 2gb like you are now.

Ok. So from what I understand if I get 2x1GB I will get better resuts than buying 1x2GB and that they should also have the same clock as the ones I currently have (800MHz). I´ll just do that then. Would it be worth getting 2x1GB Kingston ram instead of Apacer for an extra 6-8€? Also does the fact that I will probably upgrade to 64bit in the near future to utilize all the RAM have any effect on the RAM I should get (sry for the bad wording)?

So I ordered 2x1 GB Kingston DDR2 800MHz CL6 memory. Now I discovered that the RAM I currently have is CL5. Is this a problem?

No, should be fine. The two channels have separate timings, and even if you mix them up my mistake, the timings will be adjusted to match the slowest set

Finally got 64 bit windows 7 installed. Swear I've never had so many problems with an OS installation. First I burned the disk too fast and I couldn't complete the installation because of that. Of course before I realised that, I tried every possible trick in the book to complete the installation which took me about 2 hours. When I finally zeroed in on my issue I had obiously already formatted my HDD so I had to reinstall the 32 bit version in order to burn another copy. When I finally got the OS installed Windows reports that only 3 of the 4 GBs of RAM I have are usable. You can imagine my frustration by then. Another 15-30 minutes and I found out that I have to enable some remap memory setting in my mobos BIOS. Finally I had overcome every obstacle and had become a user of the 64 bit version of Windows 7.

Next time, use a USB stick mate to install Windows from mate, no burning issues and it's faster
Doing it myself as we speak, so far it's taken about 5 minutes, 75% with copying files, so won't be much longer from here on

Well damn! Another problem. Cpu-z reports my Ram speed as 333,6 MHz while as far as I know DDR2-800 should run at 400MHz and Cpu-z showed that before I added the 2 sticks of Kingston. What am I doing wrong?

Check the BIOS? And you're sure all 4 sticks you have now are DDR2-800?

The BIOS are on auto and yes I am 100% that all 4 are are DDR2-800. I checked the A-Data before I put the Kingston in and the exact Kingston model I bought is kvr800d2n6. Maybe I should force 800 MHz in bios?

Should be safe (400MHz btw, 800 = Data rate), just make sure to set the timings to the SLOWEST chip you have.

Actually I already tried changing the timings to CL6 in bios (without changing the frequency) and all I got was an Overclocking Failed message and after that an automatic BIOS reset.
Also a few screenis to illustrate:

Set all latencies manually. Force 400.

I don't know the layout of your BIOS, but if you have per-channel settings use that. 5-5-5-18 for the channel with the A-DATA chips, 6-6-6-18 for the Kingston channel.
If not, set all 4 chips to 6-6-6-18. The SPDs for your chips are weird btw; the SPD spec for 266 are identical, but above that the Kingston chips get slightly slower timings it seems. Also make sure to check that DRAM voltage is fixed to 1.8v

I'm having problems trying to get my computer to start after changing the timings and frequency. My computer starts but I get a blank screen and nothing happens. After cutting the power and waiting 30 seconds or so my PC starts but I get an overclocking failed message with choices to either enter the BIOS or load default values.
Here are a few pics of my BIOS' layout:
| Spoiler: | |
I changed CAS latency to 6, RAS to CAS delay to 6, RAS precharge to 6, RAS Activate to Precharge Delay to 18 and left everything else untouched. Currently I have SPD enabled. Also in the second pic you can see the options I have for RAM frequency. I presume I have to choose DDR2-800MHz. Sry if the answer is apparent but I'm a noob when it comes to RAM.
PS. Pay no attention to the fact that I have Memory Remap disabled as this right after the BIOS reset and I hadn't enabled it yet.

ra, by default is usually linked to your fsb, which in your case is 333, you have to select unlinked to be able to set it to something else.

The RAM was running at 400MHz before I upgraded it to 4GB so I doubt it's that. Unless I misunderstood you.

Seems your motherboard disapproves of differing timings, got any voltage settings to check?

If I set AI tuning to manual I can set memory voltage. Currently it's on auto. Would there be any point in just leaving SPD on and switching the frequency to DDR2-800? Could it be dangerous?
EDIT: Assuming that I can't get the RAM to run at 400MHz should I return the Kingston and get a CL5 model instead or is the performance hit small enough that I shouldn't bother?
