Can someone point me towards a DDR2 timing parameters tutorial?

The HZ, as pointed out by many, is able to overclock above 1000mhz. That's like a Memory worth £300 at the price of £172ish. Bargain!

WOW!! Plus they're £3 cheaper

. Sounds good, thanks guys.

Little question, intel nub here

So: G.Skill 2GB DDR2 LA PC2-5300 (2x1GB) CAS4 Dual Channel Kit (F2-5400PHU2-2GBLA) (MY-012-GS) paired with a E6600, would give me potential for a light green brack under 3ghz clock?

So I'd need some expensive, good stuff for a good oc, with intel having to have a 1:1? I'm used to being skanky with cheap ram and bumping up on a divider, thats simply a no no for intel?

Saw theres a second page! Looks like the gskill HZ 6400 is the one to get

PC5300 is stock at 333MHz, increasing the 2.4GHz E6600 to 3GHz (+25%) for a pretty decent overclock. Since the PC5300 might run a bit over 333MHz, over 3GHz on the CPU should be on the cards.

DDR2 timings are the same as DDR timings in what they do. Slack timings make hardly any difference because of optimisations in the core 2 processor, go for bandwidth. I've got myself some nice PC2-8000

That must have set you back a few coins

Pardon me but I really don't see the point, I mean with the G. Skilz HZ at such a price, perhaps you bought it awhile back?

Damn, those PC2-8000 cost way more than any E6600 and below...

Thanks mate, really helped

Whats the point buying PC2-8000 when for the price you could have saved buying the PC2-6400 HZ kit you could have bought an E6700?

I presume you're replying to monkeypants?

Bwahahahahaha... T'was an RMA from OCZ

Sorry, forgot to mention also that the HZ must be dated May 06 or later. Look out for the 0605 sets as these use the Micron chips, earlier versions use the inferior clocking Elpida ICs.

Hi,
Just recieved some HZ memory from OcUK today. I assume the 0605 is the first part of the serial number? These chips are 0606 black spreader. Do these use the Micron chips or is it just the 0605?

Kesnel · 20 Jul 2006 at 17:31

Any later than 0605 inclusive have the Micron IC, so you're ok with 0606, same month as mine.

ive just ordered some hope they are the latest ones!!

I went for the Team Group DDR2-PC5300 (DDR667) 3-3-3-8 Micron based RAM instead. Was slightly cheaper - uses same chips etc so went with that. And is guaranteed for tighter timings if I don't use 400mhz say.

Im sure I have read that the memory timings are not as crucial to Intel chips as they were on the AMD's.

Im a right in suggesting that Intel's prefetcher masks the latencies of memory and so reduces the importance of tight timings. So if you are using a Conroe, altering the timings will not give you the gains it did when altering the timings on our AMD based PC's.

Basically, yes. It does make some difference but it is more 5% on average only. Still, I didn't buy the RAM for timings really, more for clocking potential and price.

Surely if you buy a mid range Conroe, then DDR2 6400 800mhz is a complete waste since Conroe will never be able to reach the max. bandwidth of this memory which is 12.8gb/s, even when the cpu is oveclocked. The Intel Nforce 590 is going to be limited to DDR2 5300 667mhz and this reaches 10.6GB/s but still more then enough for the fastest Conroe.

The only real benefit I can think of for having faster memory is in situations where hard drives, pci cards, and other i/o devices uses bus mastering to read from memory directly without going through the front side bus. But overall I reckon there will be no difference in performance between running memory at 667mhz or 800mhz.
