1366 X58 Xeon 5650

Running with 1.4vcore and 1.32v QPI, using a Swiftech H220-X 'proper' AIO cooler but because this is pretty much overkill for the 95W Xeon I can have everything turned way down to near silence using an Aquaero 5 Pro fan controller and still only get max 65c load temps. Though you could achieve close to those temps and near silence with a Noctua D14/D15. PSU is a Corsair RMx 600w. The fans in these don't even start up until you start putting it under load and because I'm using just over 300W at normal load then the fan never comes on.
GPU is a passive Nvidia GT720 so no fan and hard drive is just one 256Gb Samsung 840 SSD which once again makes no noise.

Which means although I can be right next to it I have to check the light to see if it's on. ;)

Nice. I have a D14 but temps get really high at 4.5 / 1.375. What you running bclk and multi at? May not be brilliantly seated or my room might be a bit hotter than your average... but don't think I've the headroom to do any more than 4.5

Ok, so I took the gamble and pushed her to 4.63 all cores with 24x…it would log in to windows, but any load would crash her, and I was already at 1.44v vtt; so I decided to call it a day.

I then dropped the blck to 188 and deducted 1 voltage step whilst also enabling c-states for 25x. I now have a static 4.51ghz that turbo's to 4.68 - 7ish. So far so good - and the rig feels like a new system. Anyhow, Volts are still fluctuating from 1.424 - 1.44 - so I'm a little apprehensive with these figures for 24/7 - which it has been running at since? What are your thoughts?

Also, I'm after some more ram - and I'm completely ignorant on the topic. I wish to buy a 4x8 32gb set, and just use 24gb - does anyone have any recommendations? Can I just use sticks labelled for more modern chipsets and ignore the profiles and set manually; or am I dreaming? Thanks heaps in advance :)

Make sure it is up to 1.65v rated and then shop for ddr3.

I picked up a set of these in a sale. Just dropped them in and set to xmp profile. You could buy a pair and then a single stick of the same ram should you so wish.
 
@Kelt
Hmm, yeah - immediately I think of 3 sticks for tri-channel, but you may be right, as I think some boards could run 4 sticks and keep tri-channel -- something like the usual pattern, but then one in the fourth [or specific ] slot or something; I will have to do some research. But yes, If I can get 32gb to work - absolutely ;)
Cheers @minicle - So as long as I keep to 1.65 rated ram […or does that also include 1.5v, known to overvolt to 1.65 as well] I should be fine irrespective of dual/quad marketting etc.?

Cheers guys, super helpful!
 
Yup. That's exactly what I'm doing, running 4x4gb in tri-channel. You're correct in that you have to put the sticks in specific slots.
 
current setup is an i7 920 (modestly overclocked) & a p6t motherboard. i've read through most of this thread (all 70 odd pages :)) & i'm tempted with switching to a 5650. Although not specifically mentioned, i've a feeling the 5650 would make video encoding noticeably faster (programs like handbrake make 100% use of all cpu cores), while also running cooler.

But i have a dilemma/am uncertain. Would likely be a nice upgrade for me but a few people replying to this thread have mentioned either teething problems getting the setup working or even things like bent cpu pins, especially when their i7 920 has been in place for several years. Then again, many other people make it sound pretty easy.

Given that my current setup is my main pc, does everything i need it to (including playing the latest games), has worked fine for years & i don't really feel the need to upgrade yet, is it worth taking the 'risk' on this (in case something goes wrong during installation). I don't want to mess something up which still works really well for me. I'm using the word 'risk' from the point of view of a newb when it comes to replacing cpu's, updating bios & setting up an overclock ;)

Or, is this the type of thing you'd go for on something other than your main pc if you can afford to get it wrong - you're doing this upgrade as more of an experiment or something to overclock &, if something goes wrong, no big deal because you haven't lost much (money/hardware) & you have another pc you normally use?

Bottom line just do it and don't do anything silly in the physical process and you should be fine.

My original i930 was in for 5 years and lifted out fine. No looking back for sake of those extra cores and lower temps.

I am running 3 x 4gb for 12gb in bank 0 - you would have to check your motherboard manual - but I suspect if you dropped a 4th stick you wouldnt get full benefit from that channel? Try it with 4, if you have any issues remove the stick from bank 1.

Ram rated - 1.5-1.65v would be fine.

It's better to run dual-channel. If you run 4 modules as tri-channel config, only 3 of them will run in triple-channel mode. One will be very slow and run as single channel (you will have 12GB of fast memory + 4GB of slow memory).

For Nehalem/Westmere, there is a tiny performance difference between dual-channel and triple-channel. But dual-channel is much faster than single channel.

What's the best program to show any differences?
 
Check THIS THREAD I posted a while back. You can run 4x RAM modules in 'Flex Mode', three of them run in triple channel and one runs in a kind of hybrid single mode. I'm running it with 4 x 4Gb Corsair Vengeance.
 
I'm running 2x 8 GB and 2x 2 GB and I think that's in the manufacturer-recommended triple-channel and single-channel mode. So basically the first 6 GiB runs in triple channel, the next 12 GiB runs in dual channel, and I guess the last 2 GiB runs in single channel? No idea how it works but it's not slow or anything. Might actually try some benchmarks with it in the two configurations (this and simple dual channel) if I can be bothered.
 
got one of these today paid £40

How comes in Cinebench it shows 4.14Ghz but your CPU-Z shows ~4.5Ghz?

I'd like to see that at ~4.5, that should be good.

My watercooling loop is almost done so hopefully will be able to do some overclocking benchmarks in a week

Turbo Boost most likely. 20x v 22x with high BCLK makes a big difference and some applications won't take account of that in their calculations of clock speed.
