Ivy or complete change to skt 2011?

Eeeeeek!

Just asked them in customer service section to change 3820 to 3930K

Figured as I was going X79, I may as well take full advantage getting a six core.

Most expensive CPU I have ever bought!

This system should last me friggin ages though! Hell, the 2500K probably could have lasted me ages :D

Have gone with 3820 and Gigabyte UD3 (because it had the perfect spacing for my cards) and with 10% discount was down to £210 and £135 respectively, and once I sell my stuff, will probably cost me less than just getting 3770K.

Decided may as well get some 16GB Samsung Green ram.

Just couldn't bring myself to pay £400 for 3930K right now.

Only aiming for about 4.5Ghz, and at least it will give me an upgrade path in the future, even if it is only one day picking up a cheap 3930K. But hopefully ivy-e will deliver.

Great choice and a bargain. I got the same but paid a bit more than you (£390 in total).

You will get to 4.5 easily. All I did was set the RAM timings and voltage correctly. Set the Vcore at 1.4v and then up'd the divider (or whatever its callled) to 125%. The pushed the mutiplier up till it wouldnt run prime95. Some people run at 1.45 or 1.5 and seem to get 5.0 but I didnt want to risk that high.

BTW - watch the cooler. My SLI would not fit so I had to point the cooler (Noctua) towards the GPU and not out the back of the case which is not ideal. If you have a bigger case you can prob use the 2nd and 4th slots. My case is too small to use the 4th slot.

You wont be dissapointed.
 
Man, I hate my indecisiveness!

Decided, if not too late, to stick with 3820.

I just don't see myself having much use for the 3930K at present, or being able to notice any improvement outside of benchmarks.

One day I may need the power, but not for some time!

Decided to replace my 64GB SSD boot drive with 120GB instead :)

I spent the money I saved going 3820 instead of 3930K on a 240GB SSD, much more useful for me :)
 
Don't see the need for x79 unless you need the extra cores and/or extra memory slots.

I honestly don't think there'll be much in the way of an upgrade path, IB-E probably won't offer much over SB-E, we might get a few hexacore CPUs later in it's life time but by then Haswell will be just around the corner.

The only real advantage so far about IB-E will be 8-core (16-thread) CPUs. I'm hoping that by the time IB-E comes out, they will have ironed out the current downsides to IB. The simple fact that there is no onboard GPU in IB-E will mean that to make any significant changes from SB-E they will have to focus more on the CPU architecture (as opposed to the main change of IB over SB being the GPU).

Depending on how far off Haswell actually is from launch when IB-E gets released will determine whether or not I upgrade or pick up a second hand 3930/3960.

That pretty much sums up my thoughts.

If I went 3770K Ivy, that would be it. I would have happily if I felt that I was guaranteed 5GHz, but this is looking unlikely.

And going X79 as I have done now has cost me roughly what the upgrade to 3770K would have.

I didn't want to change boards again, but it seemed like the smart thing to do for future proofing and hopefully keeping base system for a long time.

Won't be pushing for insane overclocks, but I will do a bit of testing to see what the system can handle.

And to be honest, am quite looking forward to just running everything stock for some time :D

Just hope Intel don't decide to skip on Ivy-E
 
No longer often get very excited for pc upgrades these days, but was quite excited when got my 7950 and really excited to get this all set up.

Can't believe I have pretty much bought a whole system again.... 3820, X79 UD3, 16GB Samsung Green, 120GB boot SSD and 240GB games SSD.

Oh, and an OcUK mug :D

Going to be a sleepless weekend though...

Can I get tips on how is going to be easiest to try a quick OC to 4.5GHz? While I am not likely to keep the OC at moment, I just need to check I don't have dud CPU/Mobo.
 
Have a read through http://www.overclock.net/t/1189242/...anations-and-support-for-all-x79-overclockers

Should tell you all you need to know about overclocking X79.

However, if my 3820 is anything to go by, you should be able to set the CPU BCLK Strap to 125MHz, the multiplier to 36, and leave the voltages on offset mode, adding maybe .050v or .075v. The CPU can happily manage its own voltages up to it's turbo level + 3 bins, and 4.5GHz is only just over spec for that.
 
Thanks. That will come in handy.

Just need to stop myself from seeing how far it will go, provided I get decent cpu/board :)

Do you run yours at 5GHz 24/7?
 
I did for a week, but I've backed it off to 4.75GHz now for 24/7 running, although I do clock it up for heavy gaming and benching (new drivers, new hardware, etc). I might put it back to 5GHz+ once I've swapped my fans on the radiator and got some more focussed flow over the board VRMs.
 
Will probably get less out of my system, as it's not exactly a top of the line board, but at £135 was, in my opinion, very much worth it.

Knowing I can get 4.5GHz will be enough for me I think.

Just not sure if will be using the Zalman Flex or Kuhler 620 yet. Might have space issues with the Flex
 
ARGH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Something had to go wrong...

For all the money I have just spent getting all this stuff, t never crossed my mind that I would need a new cooler!

Silly, I know. Did find 2 screws which are enough to keep the Zalman Flex firmly in place, so that I feel cojident enough that I can get my windows installation done, but I won't be stressing the system at all.

Normally the place where I can order things to come evening delivery has nothing that can be delivered tomorrow, and have no idea where I can get something locally :(
 
Well, the Zalman is quite secure with the 2 screws I found that fit, so have been doing a bit of OCing, just to check things out.

All the voltages and stuff are far more confusing that the Z68 I had before.

It's currently running at 1.32V without any sort of load line calibration, so under load is dropping to 1.284 under load at 4.375GHz.

Been running IBT on max for a little while now and seems stable at those voltages/clocks, so maybe I have a decent chip on my hands, as if it keeps going at this rate will be able to do 4.5GHz with 1.3V, or maybe even less.

Temps haven't hit 70 yet, which I am sure I can improve once I have a cooler that I can secure correctly.
