how tight did you go? I tightened mine up slowly going around to each screw giving it a few turns and then onto the next so the pressure applied was as even as possible all the way around.

I did this until the screws started to feel difficult to turn and then I turned them slightly more until the heatsink seemed to be tight enough that it would never move and i could pick the motherboard up by the heatsink with everything feeling really solid.


When you apply your paste because you can not rotate the heatsink 30 degrees each way to spread it you need to use half as much as you normally would say a 2-3mm grain of rice spread it into a 10p sized circle gently with your finger and then put another 2mm of paste in the middle of that cirtcle but let the heatsink flatten it.

I'm getting 27-30c when browsing the net and around 49-52c 100% load on all cores thats with a 4670k though! but at gigabytes auto overclock 4.3ghz settings that used a stupid 1.35 vcore I was getting 60-65c full load

I tightened the screws in turn to try and spread the paste evenly, and everything felt secure at the time!

I've just tried another run of Prime95 for about 40 minutes after manually setting the fans to maximum and leaving the side of the case off, and Core Temp is showing 76-82 degrees but saying it hit a max of 93 while I was out of the room.

At idle, temps are around 30-35, which isn't too far off what you're getting, but clearly something isn't working correctly to keep it all under control under load. I guess re-seating is the next step - any recommendations on what to use to clean off the thermal paste before re-applying?

Also, how much difference would the orientation of the heatsink fan make? I could only seem to mount it with the fan above or below the heatsink due to the brackets restricting the placement, and the fan is currently pointing down which means it isn't lined up with the front and rear case fans. Could that be driving temps up like this?

So we've got 2 confirmed OEM chips pre tested and sold as new? (one of them faulty)

I recently read a post from an OcUK employee that said that they don't sell OEM chips that have been pre-tested as new. Whats going on?

Do you have a link to this post?

Awesome ! Thanks Rossi~

Yep. Looks like they've been telling porkies. I hope EVERYONE who gets an obviously used OEM processor returns it. Contact 5UB in the customer services sub forum and he'll sort it for you. Hopefully they'll refund delivery costs too.

Just sending an RMA now and I'm sending the CPU back as it should have been received, in a proper plastic protective container and padded envelope.

Lol! I went retail this time for exactly the same reason. Not saying any of its true, but there are too many stories around OEM chips now for me to trust them.

Just checking; OCUK are making a profit from scaring people over selling used as new?

Had my 4770k prime stable last night @ 4.4GHz 1.152V, ~65°C on H100i. Didn't have time to play much after the build, just a quick run around in BF3. But it was sitting below 50° in game and core temp variance was no more than 5°.

I'm going to try pushing more tonight and may well delid, depending on what happens. Its noticeably quicker than my i7 920 though, which wouldn't do much over 3.8GHz. Also quieter as my fans are spinning up so much. There's allot of disappointment aimed at Haswell atm, but I'm quite pleased with it so far.

A big surprise for me was how well Win8 Pro behaved with all the new hardware. I was expecting to have to do a fresh install, which I'll probably do anyway tbh. But I thought I'd try booting up for lols and after installing the chipset drivers from the mobo disk it was fine. No reactivation or any major drama at all.

Not this again!!! I only bin CPU's that are stocked for systems. You buy a retail chip its never been touched or an OEM on the site = same!!!

?

This can interpreted in several ways, however how is it that customers are receiving binned CPU's if they are "are only for systems"?

 

[Westyfield2]

The evidence provided on the last few pages suggests that this may not be the case.

Then a particular retailer has shafted their customer.

I was talking about OEM vs Retail in general, how it leaves the manufacturer.

 

[Westyfield2]

OcUK have stated many times before (remember the whole hard drive flooding price thing?) that stock to be built into systems and stock to be sold as components to customers are two completely different sets of stock.

Not this again!!! I only bin CPU's that are stocked for systems. You buy a retail chip its never been touched or an OEM on the site = same!!!

Interpretation: "I only bin CPU's that are in the set of stock designated for our system builds - this then determines which system build it goes in. If you buy a retail chip then it has never been touched. OEM chips [in the set of stock for customers to buy as components] are also untouched, they are just the same as retail chips apart from the warranty and the fan."


This is why OcUK don't do the dead-pixel check thing on monitors that some other retailers do - as otherwise they'd end up with a pile of stock that can't be sold as new (as it has been opened and tested) and they'll have to sell off cheap as they're the ones that had dead pixels.

I have mine mounted with the fan on the memory slots side which I believe is the "correct" way but I don't think it really matters I'm guessing it's just because the air coming from that side will be a lot cooler.
maybe having how yours does lets the GPU heat effect the cooler a bit but theres no way it should jump from 35-90c

What does your vcore show as in cpu-z when your CPU is at load ? maybe your motherboard detected it wrong.

I think stock should be somewhere around 1.130
1.25 is what people are using for high overclocks which does give really hot temps like 80c+ at high overclocks (on 4670k anyway I'm assuming the voltages won't be to different)

BTW DO NOT USE THE WHITE FLAT PLASTIC SPACERS ON SOCKET 1150

 

[JWildfire]

You know, I don't plan to push this OEM chip that high despite being on water.
If I can get it to 4GHz, maybe even 4.2 i'll be happy enough.
I just want a valid explanation from OC, I've made a webnote.

4ghz is easy.

I upped my vcore to 1.160 from 1.130
set the core to 40 and the uncores to 40 so it doesn't try to overclock the ratio and booted straight in to windows fine getting 5c higher under load and the exact same idle temps.
Every chip should hit 4ghz easy

That guide thing I posted says even the dog chips can hit 4.3ghz although at 90c because they will probably need around 1.25v which some good chips are doing 4.7ghz at
http://forums.overclockers.co.uk/showpost.php?p=24398237&postcount=1427

I guess over 4ghz heat starts to become a big issue but 4ghz at least in my experience is nice and cool still

I'll post the results shortly, just waiting on new water parts to arrive via fedex. Speaking of which where the hell has he got to...

Thanks for the reply. CPU-Z shows core voltage at 1.068 under load - surely that would result in even lower temps, not high ones?

Do you mean the clear plastic spacers for the mounting bracket on the underside of the motherboard? The installation instructions that came with the cooler shows them being use for all socket types so I did use them - should I remove them then?

Same for me in win 7 upgraded from am3

Everything is running nice and windows seems slightly snappier and my games have better FPS so I'm not going to bother doing a fresh install

if you read the instructions it says not to use them with socket 1156 even though the illustration shows them being used. (socket 1150 uses the same holes etc so I'm guessing your not meant to use plastic spacers with 1150 either)
it says with those the pressure might be to much for the board, which suggests to me your cooler is not tight enough or your board would likely have been bent or snapped and this is why your temps shoot up so much

The actual instructions say to tighten to the end of the thread , I'm not sure if I went that far, I'm guessing your likely nowhere near the end of the thread if your using those plastic spacers under the board without issues

Glad I didn't tighten enough to snap the motherboard! Should I be able to just remove the spacers one by one and then tighten the screws again or will I need to fully remove the cooler and reapply thermal paste now? Obviously I'm keen not to make anything worse!

 

[lettuce]

Is this some kind of joke?!

Yes my CPU also has thermal paste smeared all over it like a 5yr old dinner table and signs of use.

Jesus, and I was hoping my situation was a 1 off, obviously not
