Memory Recommendation Request

Hey folks

Wondering if anyone can advise on some DDR3 ram, I'm looking for a 2000mhz tri chan pack totalling about 6gb. My main problem is i don't have £200 on Kingston HyperX and I definately don't have £300 for Dominator.

Is what i'm looking for even possible for less than £200? Lower frequency single channel looks like £150 for 6gb which is... cheaper.

Well, any advise at all, even recommending a different setup at all than 6gb tri, would be appreciated.

Any info on the system this is for, feel free to ask, of course.

Hi.

What site do you prefer for buy the RAM?
April 6, 2010 6:48:08 PM

I shop around, my local place is a bit above average on price. I'm not bothered about buying from anywhere online based in the uk.

If I had to name somewhere, probably http://www.overclockers.co.uk/

I can browse myself though, I was more looking for a recommendation of something I may not have come across myself, and opinion/advice on what actual setup to go for.

My inability to edit posts is rather annoying ><

The main reason i'm posting here is because there are so many combinations, and I can't pick the best of both. I can't go for something like a 6gb tri chan pack of 2000mhz ram.

Do I got for a 2k 4gb dual? 1333mhz 6gb tri chan?
singles, dual, triple
1.3, 1.6, 2k
2gb, 4gb, 6gb

That's what, 81 combinations? I just don't know what to prioritise really, and I may just be irritatingly rambling now, but I feel I may aswell mention its for a gaming rig. Can't think of many other reasons why I'd consider such powerful memory, but hey, if it wasn't obvious.

What are the rest of the components you're considering? The triple-channel RAM kits are only for the Intel LGA 1366 chips. If you're using anything but one of those, you'll want a dual-channel kit.

The price difference between 1600 and 2000 is enough to consider just sitting at 1600.

Trident packs out of stock everywhere I look

Three channel works only with i7 processors. Also, about the frequency we should know if your motherboard has support for higher frequency, what's your mobo?

DDR3 2000 RAM is a waste on most systems since they're all rated at CAS 9. I would just stick with some quality DDR3 1600 CAS 7 RAM. If you're still hung up on wanting DDR3 2000 RAM, see if you can find either of these kits locally:

its for a rampage 2 board (not gonna be able to afford rampage 3 even if I save until its release) and that 2.6ghz i7 for the 1366 socket, since the board is capable, I thought i'd take a look. Barely considered it might even be possible for three dual kits... I dont know if that would actually work though.

How the... sorry, the quote thing seems to have gotten the better of me there, and like I said I can't edit for god knows what reason.

I don't know if you can find this RAM in stock locally, but it's hands down the best 6GB RAM kit IMO. It doesn't get much better than 1600MHz CAS 7 while running at the DDR3 standard 1.5v.

locally? I can barely find it on google. Reviews everywhere yeah, but to actually buy? Not even ebay, ripjaws everywhere. Mostly asia supply or something? I dunno. The price didn't look to hot. But really I can get alot of good options looking at a 1600 tri kit

Just get whatever CAS 7 DDR3 1600 kit you can find that runs at 1.65v or less.

CAS 7 1600 MHz DDR3 is good. the Patriot Viper II Sector V kit I'm using was quite a reasonable price. Might be something to look for (don't know if they have 6gb tri-channel kits for it though).

My son's box has an Rampage 2 Extreme and we stuck a set of Mushkin 998692's in it running at 6-7-6-18 timings. On this side of the pond (US), the Mushkin DDR2000 w/ 8-8-7-24 timings goes for $289

Whereas the Muskin DDR3-1600 w/ 6-7-6-18 Model 998691) go for $269

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Given the above, we should examine why get DDR3-2000 ? Read this.

Most peeps will pop for DDR3-1600 because, most of the time, it provides only a minimal cost increase over DDR3-1333. Using a 920 for example

133 BCLK x 20 CPU multiplier = 2.66 Ghz
133 BCLK x 8 Memory multiplier = 1066 Mhz

167 BCLK x 20 CPU multiplier = 3.33 Ghz
167 BCLK x 8 Memory multiplier = 1333 Mhz

200 BCLK x 20 CPU multiplier = 2.66 Ghz
200 BCLK x 8 Memory multiplier = 1600 Mhz

I get so confused with timings i dont even bother to modify them anymore. Just looked at some guides now to see if I could refresh my memory a little. They talk about timings like 2-2-2-5 and give other examples and say lower can be better but even good ram has timings like 9-9-9-25 and i just wonder wtf is going on when ram has 5x the latency given as examples when i assumed it would be much lower as an 'upgrade'.

I might just buy a 6gb tri chan pack of corsair dominator dhx stuff.

You're looking at some very old guides if they're talking about CAS 2 RAM. Those ratings were for old DDR RAM. The absolute fastest timings available for DDR3 RAM is CAS 6, but they're ridiculously expensive. That's why I suggested CAS 7 RAM. Their prices are good and the performance is also very good.
