**OcUK Extreme Haswell bundle - A review!**

Tell him to go for the x-oc, you simply don't get the features it offers on any other board for that price!

Water and roughly 1.33v should net you 5ghz on one of these :)

he ordered his stuff yesterday :D 780gtx water cooled and a corsair 540 2 rads was gunna go with a 7990 but wasnt sure if it fit in the 540 with front rad in.

should be a great fast rig :D
 
Will the Alpenföhn K2 Mount Doom fit in a Coolermaster Cosmos 1000? also I have 2 7970s and an ASUS Essense STX Pci express sound card will they all fit?

Sorry for the dumb questions but help an old man out here :)


I'm seriously tempted with this bundle with the Gigabyte OC board, is there anything wrong with the base MSI one?

My cheque should be clearing today, so I can order my bundle, although l will be ordering with 16gb ram and the asus formular board, but without a cooler, il be using my Corsair h100 I, until I have saved enough money for the new cooler, or perhaps il go full wc again. then I hope to push the cpu some more ,

All ordered cant wait...... feels like Christmas.

Ah hmmmz, now time to start saving again so I can see what my cpu will do.


A question if I may.

What sort of voltages can I expect ? im presuming at 4.6 the voltages (cross fingers) will be pretty low, hense the price?

Usually around 1.3v but you may be able to get it lower.

Don't be fooled by the seemingly high voltage, it will run very very cool in comparison to retail chips!

I have mine watercooled and had it at 1.18v for 4.6Ghz. Have it at 1.28v, 4.8Ghz now on the asus formula and appears stable. It came set at 1.3v.

Only thing I wish was that the temperatures across cores was a little more even but they are all around 50 to 55 running any game so who cares :p (biggest difference is up to 6 degrees between core 2 and 4)
 
You generally get core temp variances on most multi core chips, should only be of concern if the difference is 8-9c+ in which case its reseat time :D

How much of a temp drop did you see going from 1.3 to 1.18v? Seems to scale well have you tried out 1.4v yet?

Just tested it with a run on cinebench and got a difference of 8c :( hmmmm I have re-seated already but just cant see it being a seating issue when it is just 1 core and that core is cooler not hotter?

The drop in volts gave me about 5c I think, cant really remember but it was barely ever going above 50c, I think.

I haven't taken it above 1.3v yet :)... will do when I push for 5Ghz :P

At the moment I only have a 7870XT graphics card so this is all "just because I can" at the moment! (Waiting for the pesky R9-290X) and some more funds! :D
 
Been playing around with my bundle, tried 4.8 with the standard 1.3v set by ocuk but no luck. But been trying up to 1.35v at 4.8 and still blue screens within 10 secs of prime. Not sure if I need to mess with some of the other settings etc. But it's approaching 1.4v just for 4.8ghz so 5.ghz might be a challenge :S

What motherboard/cpu paste/memory are you using please

So guys keep my 4.8Ghz sandy or switch to one of these, what do you think?

The sandy is in a Maximus Extreme V with OCUK's 240mm Fathom cooler.

In all fairness outside of benching you'll notice very little moving from 4.8 sb to 4.6 hw. Though I suppose it depends if you're on a 2500k or 26/700k? If the 2500k, bf4 appears to be crippling 4 thread chips so a move to 8 thread haswell would be sensible. If the 26/700k you should be fine :)

My 4th core is also always 5-8c cooler than my others. I have used two different coolers, one seated by OCuk.

I believe it's got more to do with your IHS seating than your cooler, and that's done in the factory.. so unless you delid, you're gotta go with that. I guess you could say the IHS is not seated properly on the 3 other cores :P

Intel processors have a problem with the IHS anyway on ivy and sandy. The contact is not proper due to the glue being used is too thick.
 
Yay my bundle is on its way......... now which case do I install it into.

Corsair 800d-- Is empty
Coolermaster Cosmos II Ultra - my current rig is in

I will be getting the new Corsair 900d as a xmas present, then watercooling again.

Which ever case I choose to install my new kit into my oldest is having my cpu board ram and whichever case I don't use.

I will be using my Corsiar H100I until I have enough money for the rest of the cooling parts I need.

Is that not grounds for a RMA ?
 
we find that you end up with inconsistent core temps on the majority of chips, even after delidding. It's probably down to the IHS not being totally flat. It's not a fault, it's just how Intel make it
