DDR Ram Question

[NeilV]

Hi All
I am still stuck with DDR ram at the moment! I have 512mb of what I thought was 400Mhz (Silly me believing the label on the module ) Auto Detect says 266Mhz wont run stable @ 400Mhz. Shop was raided and has ceased trading.

Anyway I intend to buy 1Gb of 400Mhz but have seen to different Modules within my price range.

Corsair (VS1GB400C3) 1024MB, DDR400 / PC3200, non-ECC, 184 DIMM, unbuffered, CL3, 64Mx8 DRAMs, Lifetime Warranty

AND
OCZ (OCZ4001024V3) 1GB DDR-400 PC-3200 CL 3-4-4-8 VALUE MODULE (LIFETIME WARRANTY)

I believe the Corsair is CL 3-3-3-7. How much difference would this make?
I intend to remove the SLOW 512Mb that I have currently. Is this the best thing to do? :?

I have a P4 650 OC'd to 3.78Ghz, an ASUS P5P800S MOBO & a GF7600GS 512mb Graphics card, so I am assuming that it is the RAM that is slowing my system down.
PS I am running XP, don't want toslow down the system any further by installing Vista.

Any Thoughts!!!!

Cheers
NeilV

It won't make that much difference, but i'd be willing to bet that the OCZ value-RAM will be more liable to reach the 222MHz that you need. I have some of the (semi-cheapo) OCZ "Premier" RAM, it's very cheap(if you can find it) with timings of 2.5-3-3-7, and can run up to ~244MHz...still at those decent timings. GL

I just found it on Newegg. OCZ Premier 1GB

Thank You 1Tanker.
You very cleverly filled in all the info I missed (Sorry ). I think what you are saying is that to get the 10% FSB increase on the memory I should go with the OCZ module. I am buying from the UK so prices will vary.

Not quite sure about Dual Channel either would 2x512 be better than 1 Gb, bearing in mind that I am running XP & a non-dual core processor, or is Dual Channel something different again :roll:

Iwas going to get 1x1Gb stick so that I could get another later when I had more cash.

Should I look for Higher CL values?

Thanks Again

The 2x512 would be better if you have dual channel capable mobo (haven't looked up specs yet). If you only have 2 slots for memory than the 1 stick would be good for now and 1 stick later (if they are still selling them when you go to buy them later). 2 sticks in dual channel mode should almost always be faster than 1 stick alone of the same total size of memory, so keep that in mind.

The OCZ has slightly looser timings and so should overclock better.I would also get 2X1gig sticks if you can afford it for your dual channel.Besides,XP and other apps,including some games,run better with 2gigs of memory as opposed to 1.Goodluck.

Not seeing anywhere stating that Dual channel mode is available on the motherboard for the DDR. Maybe I'm just not finding it today (alittle tired).

Yeah, you're right. His board doesn't support dual-channel. May as well get 1x1GB stick then, and maybe get another one...later. GL

Last lot of Memory I was going to buy went out of the sale on Friday, now looking at Corsair 1x1Gb + 1x512Mb but they have different Latency, will this be a problem one is 3 one is 2.5, at this point I am not bothered if it all runs at 3 as long as it works.

Should run fine, from what I recall. I believe it will run at the slower rate, but shouldn't matter.
