G.Skill - HZ or ZX?

Vanilla_Ice · 3 Aug 2006 at 10:39

Hi,

I'm looking to order the parts to build a Conroe system this weekend. I have been looking at the G.Skill 2GB DDR2 memory kits and I am trying to find out which is the best choice of the HZ and ZX kits. Seeing as there is only a couple of £'s in it.

I will be going with either a E6400 or E6600 and an Asus P5W DH.

Cheers,

ICE

HZ. Ordered 2 kits from here this week.
Both run (so far) 460 FSB @ 4,4,3,12 timings. - This is limited by CPU/Mobo atm

One with 2.0v and the other needing 2.2v.
Great stuff

Hi,

What board are you using and what CPU? Do you have the serial number of the RAM?

I am interested to see how my HZ 'should' clock when I get the system stable. Mine is 0606 I think.

Cheers

Interesting. Why not the ZX? It comes with tighter timings as standard.

BTW I am new to DDR2.

The HZ is the fantastic one with the same chips as the PC8000 and clocks above 1000Mhz with relative ease.

Its very popular over on XS, though there seems to be issues with the gigabyte DS3 conroe board.

I do have the SN, would rather not post it here. Both kits are 0606 though

Mobo was AOpen i975X YDGa, running a T2600 ES. There's certainly more in the ram, hit a CPU FSB limit at 272 though, and theres no other higher upclock dividers available for the ram.

HZ is getting great reviews, and uses different chips to the ZX. The HZ runs a D9 based IC, so should scale well with volts holding fairly decent timings too. The ZX uses different chips (Eplida??) so probably wont clock as high.

The issues with the DS3 are that, until you manually set timings it boots at cas3. Would think 90% of the HZ sticks would run cas3 quite happily at 6400, so not sure whats going on there :confused:

How do the G.Skill's compare against:

Corsair 2GB DDR2 XMS2-6400C4 TwinX
Corsair 2GB DDR2 XMS2-6400C3 TwinX
Corsair 2GB DDR2 XMS2-8500C5 TwinX

Cheers,

Not meaning to hijack topic, but in the same situation myself, almost.

Looking for Conroe X6800 RAM, not looking to overclock, but still don't wanna be using RAM that's not good to go.
Was gonna go for PC2-5300, but with all the talk of PC2-5300 being slower due to it not being sync with the FSB, was pointed towards the PC2-6400 (800MHz). Fair enough.

'G.Skill 2GB DDR2 HZ PC2-6400 (2x1GB) CAS4 Dual Channel Kit' is the one to go for? NR is quite a huge jump cheaper, but seems to be much worse CAS latency (not that I know much of anything about CAS latency, tbh).

If you're not overclocking you may aswell save the money and get the NR, CAS latency doesn't really seem to effect C2D's that much, and you can put the money towards your GFX card

If I can do that, then that's brill, as it's quite a bit more than I was wanting to spend on RAM.

I've been swayed recently by this article

http://www.madshrimps.be/?action=getarticle&number=1&artpage=1962&articID=472

The difference looks huge on paper, though I dunno how it plays out in reality.

I dunno, I may not be OC'ing, but trying to save a few bob by skimping on RAM is something I'd rather not do y'know... false enonomy in my eyes.

Well, I done a boo-boo and selected NR instead of HZ.

So, if you want to wait until my ram is tested witha conroe...

If you weren't OC'ing though, the ZX would be the better choice, yeah?

Well the timings are slower so you would be better with the LA or even some cheap PC4200 but with the ZX being on this week only and cheaper then having a bit of headroom wouldnt hurt
