Dammit - did I just buy a dog off Intel???

[Wireline]

Hi

I really hope someone can give me some pointers here, because I have a nasty feeling I have bought a crappy 5820K off Intel-elot (to get that joke you need to have played the national lottery in the UK). None of my gear is ROG apart from a little SLI bridge I bought off Ebay 😉 is it still ok to post here? Mobo is an X99 Deluxe though. Here's the TL;DR of whats up, please feel free to ask questions and I'll fill in:

4.3GHz - 1.32V VCore, 1.9V Vinput, Vcache AUTO, 2 hours stable on AIDA64, <65 degC, unstable immediately on OCCT. 76 degC
4.2GHz - 1.32V VCore, 1.9V Vinput, VCache AUTO, stable on AIDA64 <65 degC, stable for as long as I could bare to run OCCT, but desktop became unstable right after. ~70 degC
4.0GHz - 1.286V VCore, 1.9V Vinput, VCache AUTO, stable on AIDA64 <65degC, and ROG Realbench (barely hits 60), again stable on OCCT but I hate running it. < 70 degC

I tried the ASUS autoclocking, it fritzed out at 4.3, and gave me a barely stable 4.2. With the above, all other BIOS settings are AUTO. So what else can I look at to get this chip stable, or do I just have a dog?

Unfortunately, there is little you can do when you have a below average CPU. It's either live with it or sell it and keep playing the lottery.

Thats what I was afraid of, but that said - does overclocking a Haswell-E really just come down to "whack the voltage to 1.3 and the multiplier to 45 and see how you go"? There is a ton of settings in my deluxe's BIOS, will none of them help? VCCIN etc?

[Chino]

Well, the scaling routines in ASUS motherboards are pretty much the best in the business. For the majority of users, there are two options that need changing. And as you have put it, the multiplier and the Vcore. The rest can be left on Auto.

OK cool thanks. So far I have been using only the software or BIOS to overclock. My TPU switch is still off, does this need to be on, or does using one of the other two methods do the same thing? I did try the XMP switch and it clocked my RAM up to around 2800 from 2666 which was good, though I don't want to run with OC'd RAM.

[Chino]

Anything over 2133MHz is pretty much considered overclocking in Intel's book. So if you bought 2800MHz RAM, you might as well run it at that right? 😛

You can leave the TPU switch off if you're planning to do some manual overclocking. If you want to get more into overclocking, Raja wrote an OC guide that is linked in my signature.

Hmm post disappeared, try again

Lol no I meant my RAM is 2666MHz, and the board OC'd it to 2800 😄

Thanks for the tip on the TPU 😉

If the Ram is Corsair Vengeance 2666 it has two XMP profiles. 2666 and 2800. The board probably used the 2800 profile. You can manually put it back to the 2666 XMP profile if you want. 2800 runs ok but it does put 1.35 volts on the Ram. The 2666 will use 1.20 volts which is stock voltage.

Update: Turns out motherboard was faulty, got refund and will be trying again sometime.
