post #16951 of 33575
I kind of want a 2nd kit of my RAM just so I don't have any empty slots, is that weird? 8GB is plenty but when I look in the window and see empty slots it's not aesthetically pleasing to me.

I have these:

Crucial Ballistix Tactical 8GB 1600MHz CL8 1.35v
http://www.newegg.com/Product/Product.aspx?Item=N82E16820148656

When I bought them they were $25 cheaper than they are now!

^^ Do I need 32 gb of ram? Hells no, but I didn't want empty slots either smile.gif

Not really for aesthetics, but I was like "eh ram doesn't have an expiration date and I'm sure it'll get used eventually, even if it's 2 years from now".

Plus the 2nd kit happened to be on sale at the time.

I might be wrong, but I thought they put zig zags in the traces to make distance to CPU about the same.

My reading of that review did not give me CL being more important than MHz. CL timings did reduce with speed, but despite that the conclusion was:
Quote:
In the end, we have to recommend what kits our users should be looking for. Taking the DDR3-1333 C9 kit as a base, it seems a no-brainer to go for the DDR3-1600 C9 kit for $5 more. The boost across the board for a negligible difference in price is worth it. The jump up to the G.Skill 1866 C9 kit also provides enough of a measurable boost, although the leap in price from 1600 C9 is another $15, which could be harder to swallow.

As we move into the 2133 C9 kit we tested today, we again across our test bed see a tangible jump in performance. This jump is not as much as moving from 1333 to 1600, but it is there and users wanting peak performance will be happy with this kit, though the size of the user pockets will also have to match.

When it comes to our 2400 C10 kit results, compared to the 2133 C9, it is highly dependant which kit comes out on top. Even if one kit beats the other, it is only by a small margin – not one that can be justified by a $15 jump in the price.

In my benching experience, MHz has always yielded more than CL.

My understanding has been that Mhz goes up and CL goes up at the same time, with them largely cancelling each other out to where it's no difference in non-synthetic loads. The difference being you pay a lot more for the bigger Mhz number. I can't remember the article title, but it showed 2133 CL9 being just as fast as something like 2400 CL11.

I'm thinking of a Tom's Hardware article from a couple of years ago that found CL was more important than Mhz. Not sure if it relevant nowadays, but DDR3 1600 was pretty fast when it was written.

If the CL goes up too much it does tend to lower the increase that higher frequency gives, 2133mhz c11 may be pretty close to 2133 c9, but good memory kits can run 2400 c7 - c9 too, I tend to do best at 2500 - 2700Mhz c9 or c10 on ivy bridge.

A couple years ago memory overclocking was different, the uncore & cpu frequency were untied & the memory clock depended on the chips ability to overclock the uncore.
The uncore had to be double the memory speed at a minimum, & without a $1000 cpu most chips would max the uncore at about 4Ghz unless really pushing things, so 2000 - 2200Mhz memory with tighter timings was a good goal to shoot for benching clocks, 1600 - 1866 was more common for 24/7.

Hey guys... finally found a home for the 680 Thanks again Ivan!

What 7970 or 7950 I wanna bench it so 7970 obviously but what one will have unlocked volts and that I can WC later for the build??
post #16956 of 33575
Other guys probably know what is best for unlocked voltage, for full cover water reference is supposed to be the way to go.
The soldering iron can still unlock voltage on any card, if you plan on ever benching cold, one of the gpus with a beefed up PCB can be handy, reference card VRMs can only take so much. But then available water blocks become more limited... Cards like the Lightning are getting hard to find too.

If ur not benching 7950 is a much better buy..

If your benching then the 7970 lighting or matrix.

...sell NVidia and buy Radeon ? I'm just having some fun, but I just beat the 4x CF Radeons for the absolute World Record in Firestrike Extreme for 4x GPUs (independent of make or model)...I used to be the only entrant, but then this fellow showed up with his Radeons and beat my submission.....so today, I used the delidded Ivy goodness combined with some NVidia Keplers to almost triple his score...may be you should ask Ivan for help to get your 680 back biggrin.gif (now, now, now - just having some fun - I like Radeons smile.gif )
post #16959 of 33575
Yup, I said either of those, use universal blocks, good for ANY gpu you buy in the future. biggrin.gif

The HIS X2 Turbo is a beast of a card, up to par with those.

@Joa3d43: That's one of the few benchies (along with Vantage with the lod tweak and Heaven dx9) where a 680 does best...BUT for most benchmarks and older ones too, 7970 is better. Compute shows its advantage, higher oc capability without a gazillion mods that WILL probably kill your card on ln2 too.

7970s do better in firestrike than 680s, although Titans are up top.
With the allowed tweaks, it is hard for 670s & 680s to keep up to radeon in anything dx11.
