Much appreciated - does anyone else have any tips they might suggest? Many thanks in advance.

I will start you off with some basic bits and let the guys with more knowledge help you out.

Your primary goal is to use the multi x the BCLK to increase the CPU speed.

This is pretty simple to do 133x 26 will give you the stock speed for your chip (non -turbo)

However with Xeons being linked using the QPI link you may need to reduce the default value of this to allow you to over clock the CPU speed since they are no frequency strapping for this

So you have fast ram. Good CPU and no hopefully have an idea of the QPI and BCLK
You already know about the voltages

So personally I would leave pretty much everything on Auto (assume you have windows configured)
Set the ram speed to 1333 and the qpi link to 4.6 (irrc Lowest possible setting) boot windows look at E-Leet and note down all the values.

Then you can start to play off the Volts/temps against the frequencies.

Hopefully some of the other guys have used these chips and can advise about specifics.

Hey there all. :)

I build overclocked machines as part of my job (low latency network engineer), and I've got a project on the go for one of our developers at the moment which involves a machine with the following spec:-

1 x EVGA Classified SR-2 Motherboard
2 x Intel Xeon X5690 CPU's
2 x Corsair Dominator GT 12GB (4x3GB) DDR3 PC3-17000C9 2133MHz Dual/Quad Channel Kit
2 x Noctua NH-D14 coolers
1 x Enermax Netzteil 1200W Platimax Power Supply
1 x Enermax Fulmo GT case
2 x EVGA GeForce GTX 580 Classified Ultra 3072MB
1 x Seagate Barracuda XT 2TB 7200RPM SATA 6Gb/s 64MB Cache
1 x OCZ Agility 3 240GB 2.5" SATA-3 Solid State Hard Drive

Basically, having all the kit now built and implemented, I'm looking to try to learn how to overclock it. I've got extensive experience in building overclocked Sandy Bridge machines (have built about 30 of them running at 5.1Ghz+ in data centre environments), but overclocking the 1366 platform is proving to be a particularly troublesome affair. My understanding is that I should be leaving the base multiplier at 26 as this is default for this chip, but above and beyond this I'm really rather out of my depth. Understand what Uncore/Memory/Vcore/PLL voltages are, and have a cursory knowledge of BCLK overclocking, but am pretty stuck with where to really start. Have had a look at shamino's outline , but am a bit confused as he appears to be using an older BIOS for the SR2? Any tips/pointers you can start me off with would really be appreciated - many thanks in advance.

Cheers,
