AMD nForce2 memory timings explored - Page 7

I know piotke

Just wanted to see if with these timings, the difference would increase a bit more... I like numbers

Seriously, I'm gonna test it too when I've modded my case... Maybe soon

Hiya,

Just read the article on nforce2 memory timings. I'm about to upgrade my system. I have a DFI LanParty NFII motherboard, and am intending to get an AMD XP2500 CPU and overclock up to 3200 speeds. This will mean running a 400Mhz FSB, so therefore need to upgrade my RAM to at least PC3200.

Reading the timing article, would seem that 2-2-11 are the timings I will want to be going for. However, can any recommend a good (and hopefully not too expensive) brand/model of memory which will run at these timings.
I don't mind having to buy a higher spec memory i.e. PC3700 or 4200 but seeing as i'm spending this cash on the upgrade, I just want to make sure I get it right first time!
Intending to put 1GB in the box, so am looking to 2x512MB chips. I'm not particularly bothered about them being matched pairs. Is this a mistake?

Also, i've seen articles saying that OCZ memory doesn't tend to run well in ADM systems. Can anyone explain this?

As you can probably tell, my knowledge on memory is not particularly great. So any help is gratefully appreciated!

Cheers

Don't buy higher memory. PC3700 and above, can handle High Mhz, but at sucky timings. (mostely cas 3)

You need low latency memory for the best performance.
The only ram I found that can do cas 2 2-2-5 or 2-2-11 is memory with winbond BH5 or BH chips. As these chips aren't produced any more, these sticks are very expensive now.

Currently I would recommend Corsair XMS PC3200 Cas 2 LL (low latency), these chips do cas 2 2-3-5. Or Corsair XMS PC3200 CAS 2 (doeing cas 2 3-3-5 I tought)

OR, you can buy Twinmos emory with "xxxx50B" chips.
On the left Winbond BH5, on the right the twinmos "xxx50B" 50D is crap memory.

Concerning OCZ memory, Don't know, I used PC3200 Rev 2.0, and these sticks worked fine overhere. Cas 2 2-3-5

I had a lot of memory up to now, what I can say is, that most cas 2.5 rated memory sticks PC3200 can do 200 Mhz with stronger timings, Cas 2 2-3-5 by example, they just eed a little more voltage (~2.8 Vddr)

For nForceII platforms, timings are crucial, so, you better try to find BH-5 chips if you want heavy overclocking...

Brands: OCZ, Mushkin, Corsair... mostly

Btw, OCZ aren't causing trouble on nForceII mobos, I've got OCZ RAM (but I haven't got the occasion to test my setup, cos I'm waiting for some new waterccoling elements. Not easy to watercool if you don't have the hoses

), and it won't cause trouble (Other people have bought the same RAM and had no trouble).

About the matched pairs, don't worry, normal sticks will easily work together... The matched pairs only guarantee it'll work together at the given specs... But does it justify the price? Your call I'd say...

Strange, I can't edit my post

Well, I wanted to add: don't exceed PC3500

Only corsair made pc3500 If i'm not mistaken, and guess what, these are super sticks, as they all have BH5 chips

I have PC3500 from Geil lying here..

Nice looking sticks, didn't know there was other pc3500, must be recent ?

btw, I can edit ? Prolly because I'm not normal member

Kingston HyperX has PC3500
OCZ has PC3500
Mushkin also... and so on

Thanks for the help guys. Got a chance to get some cheap OCZ PC3500 EL memory, so i'll probably take that option as it reviewed well in the link jmke gave above.
Given that it won't do the ideal 2-2-11 timings. What would be the best suggested settings to try for?
