i7 930 advice "Pic heavy"

[citizenx13]

Hello OCUK community

I was wondering if anyone is bored enough to have a look at my build below, granted it is almost 5 years old and still going strong most of the time.

It is a i7 930 on a Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard (latest BIOS), I have 3 DIMMs 6 gig total it was pre-clocked by OCUK to 4ghz but at some point in its life it crashed and lost the OCUK profile so I "winged" it and got it stable at 3.93 GHZ

For fun I clocked it back to 4GHZ but after a while it crashed, I have a lot of screenshots of the setting and was wondering if anyone could see at first glance if anything out of place.

I know its not much of a boost but if there is something out of place I could perhaps push it a bit more if i understood a bit better

Temps and volts


Hopefully some relative info:













Please let me know if there is any advice you may provide

Many thanks

Did this challenge grasp any interest?

Looking, give me a few min.

You sir are too kind thank you

1.5v qpi/vtt is waay too much

manually set it to 1.35v

for 4ghz try

21x191 bclk and disable intel turbo boost
8x memory multi = 1528 MHz ram speed
16x uncore freq
manually set cpu voltage to normal (scroll thought cpu voltage list)
set dvid (dynamic vcore) to +0.0750v
set dram voltage to 1.66v in bios
set qpi/vtt to 1.35v

enable all powersaving apart from c1e,disable that

then see what load cpu voltages are in cpu-z while stressing the cpu

do all the overclocking through the bios,dotn use easytune

Thank you very much Wazza, I will do this hopefully Sunday as hosting a LAN party this weekend (I know who has these nowadays) and don't want to have unexpected surprises

Thank you very much for your time I will update you as soon as I have made all the changes in the BIOS and stress tested

Best regards

I have a i7 950 @ 4.2GHz which I use in the living room as an entertainment system, it is essentially the same processor as yours.

I would personally only OC in the bios as software can be fiddly. So I will not give any advice on software overclocking.

I will give you a few ideas to try in the bios. Keep in mind I won't take responsibility for any issues you might encounter. Overclocking is different for each chip. Save your current profile before you start.

Firstly you should try OC with a BCKL of 200Mhz and a multiplier of 20. This should give you exactly 4Ghz and also run your ram at 1600Mhz. Make sure your memory timings are as they appear in the memory timings table pic you posted for the 800Mhz row @ 1.65v.

Depending on your cooler you could try a bit more voltage on the CPU. For reference I am currently using 1.343v. The 3XS pre-overclocked profile I received with the system had it at 1.4v! although stable, surplus to requirements. Please take care when increasing voltage and make sure you have a good cooler. Try increasing it by 0.025v steps, or something similar.

Other points of note:
UCLK frequency, mine is at 3409Mhz, any higher and it won't be stable.
QPI Link Data Rate for me is 7218MT/s any higher is a no go for me.
Look at QPI/DRAM voltage, mine on auto ~1.4v don't go over 1.4v
Look at CPU PLL voltage, mine on auto ~1.8v
Look at IOH voltage, mine on auto ~1.164v

Keep an eye on your chipset temperature.

These are the few points that I felt played the biggest role in finding my highest stable OC with decent temperature and voltage.

Overclocking is not something that can be learned easily. Sure it is done easily enough but to really do it properly you have to do a lot of studying and reading...trial and error
Be methodical and take notes as you try change each setting on its own. There are also a lot more detailed guides elsewhere online.

GLHF!
