The Gigabyte Z87/Haswell Overclocking(OC) Guide - Page 82

post #811 of 3252
Okay finally got this zoned in, at 1.17 and running around 63C under AIDA6 load. Still seeing a lot of wild fluctuation with the individual cores, each of them showing peaks under Coretemp of near 80 but only for a second and then back down into the 60s.

Gear mentioned in this thread:

Just to clarify, at bios voltage of 1.305v I get 1.320 in CPU-Z so that means I need to keep the VIN atleast 0.5 volts higher right? so 1.980 should do the trick ?

I would be interested to know which C-State can affect stability too, never though they could unless its low load stability.

I have not had time to check if I can lower Vcore a little bit. But 1,32v is crashing very quickly.
I have 4,4 GHZ now with 1,34v Vcore , 1,88v VRin, 1,2 Vring now (Bad CPU). Everything seems fine.
My temps are OK but I have delidded !! @4,4 Ghz Cinebench max 67c°, Prime max 69C°, in Games 50-63C° my ambient is about 26-27 C° because of Summer.
The Vcore difference from 4,3-4,4 + 0,09 Ghz at this point is a lot , but I hear this can be normal when CPU reaches its limit.
I wonder if other people have this as well for 100mhz more so much more Vcore ??

Pretty low temps, how much were you getting before the delid and what cooling ?

Before delidding I only tried 4,2 GHz and got up to 80-83 C° easily !
I have a Scythe Mugen 2 ( not the best cooler bud good ) with Arctic Silver under it,
and between CPU die and Heatspeader I have Liquid Pro Ultra.
Liquid Metal the only Solution in my mind between Cpu die and Heatspeader. thumb.gif

I was really happy first time I saw the temps after delid.

The liquid metal works good on delidding but my experience with the heat spreader has not been as good. I have found that just using a good thermal compound of the spreader is more than enough.
post #817 of 3252
I mean I used Liquid metal just on the Cpu die.

Bewteen CPU and Heatspreader I would use only Thermal Paste.
post #818 of 3252
Bah, my chip is not capable of 4.5Ghz even at 1.305v (bios) 1.320(actual) its also hitting 90c on my h.264 testing...

Not entirely sure if this chip is worth delidding for that extra 200Mhz more than I want!

I would sell it and NOT delid if you are not satisfied with its OC capabilities.
Because you can sell it more easy with the warranty.
Did you try 4,5 with 1,32-33v ? will probably get too hot.

By the way I have a new CPU here, will test it tomorrow. Wish me good Luck...

Its already hitting 90c on 1.305 bios voltage, I didnt bother trying 1.320 in bios unless ofcourse I delid.

Btw what do you guys use to monitor temps, RealTemp 3.70 and Tech Inferno version both give out different temp numbers.
