4Gb G.Skill DDR2 PC2-6400 PQ CL5 series

[Arcane]

Just noticed that G-Skill have released a matched set of 2x2gb 6400 modules, namely the "4Gb G.Skill DDR2 PC2-6400 PQ CL5 series". The 5-5-5-15 timing's aren't the best but it's the first matched set of 2 x 2gb dimms i've come across...anyone had any experience or seen a review?

EDIT: Doh! Wrong section, dons please move to memory...sorry.

Mushkin have had a kit out for some time, ocz have hinted at a 4gb kit too, looked for some reviews, cant find any*

I'm thinking of getting more RAM come Vista 64 time...just want to make sure I'm not downgrading.

 

[Cartho]

honestly 2GB of RAM should be FINE for Vista 64..
Anything more really is overkill, unless you do really RAM heavy stuff like serious 3D modelling etc....

Trouble is, with a 4 x 1gb, you're limiting overclock/speed aren't you? You'd have thought there would be more 2 x 2 packs...

 

[trojan698]

Yeah but the 2x2gb kits have inferior latencies and I doubt they'll clock to anywhere near the same speeds as the 2x1gb kits. Unsure what would be best clocking wise though.

Edit, there seems to be a fair few new 2x2gb kits from GSkill - http://www.gskill.com/en/ddr2.html

That's why I liked the idea of this kit, a 2 stick kit as opposed to filling all four slots...the latencies of 5-5-5-15 are worse than the 4-4-4-12 I'm running but if they clock to their rated speed of 800 then I would have thought the extra ram would negate the lower latencies in terms of overall performance?

 

[melbourne720]

Do latencies have much real world impact in Core 2 Duo systems? I heard they didn't...

Or am I trying to justify going cheap on 5-5-5-15 RAM

Ah but that's why you have 4 slots, no? This guy has 4x1gb sticks sitting pretty at 1ghz, I doubt that's achievable with a 2x2gb kit at this moment in time. http://www.xtremesystems.org/forums/showpost.php?p=1894592&postcount=17
Have a look around the bandwidth section on XS, the kits don't seem to clock too well.

They don't make a huge difference, no, but when the 2x2gb kits are the same if not more pricey than 4x1gb and don't clock as well it seems a bit daft. Fair enough on the A64 platform everyone migrated from 2x512mb to 2x1gb instead of adding another 1gb kit, but that was due to the impact running your kit at 1T had (5-10% performance difference).

Good point...the cost's about the same...if's there's no performance penalty running the 4 sticks then I suppose it's a no brainer until they improve the timings etc on the 2gig sticks...shame I fancied buying some new toys...lol.

Those latency's make baby Jesus cry!
