Need help restoring OCUK bundle overclock!

Back in March 2010 I got one of the i3 530 @ 4Ghz bundles and all in all it's been awesome, really quick and stable.

Unfortunately a couple of days ago I lost the BIOS settings and am now struggling to return it back to the same speeds whilst staying prime95 stable. I'm not overly familiar with overclocking these days so not sure what it is I need to be changing to get the last 150Mhz out of the cpu.

To the best of my knowledge it was: -

Vcore = 1.325V
QPI/Vtt = 1.31V
VDRAM = 1.66V

BCLK = 182Mhz
Memory = 1456Mhz
Ratio = 22

I think everything else was set to auto or normal.

When I got the bundle the cpu was getting hotter than expected and typically ran about 70-75°C on load, I reduced the VCORE to around 1.25V and it stayed stable at that whilst reducing load temps to the mid 60s.

I have managed to get it to run an hour or so or prime95 blend torture test at 182 BCLK with 1.2625V but when running it again this morning it failed on anything more than 170 BCLK.

Is there any chance that someone might have the exact settings for the i3 530 bundle so I can set them again.

My PSU is now pretty old so perhaps it's possible that it's not giving stable enough power any more, is there any way to test this out? It's an OCZ modxstream 520 which is a good 7-8 years old now so quite possibly due for replacement but I want to get the BIOS settings right before I spend money that I'm meant to be saving for a wedding in June :D

Any advice would be very much appreciated!


edit: it seems to run the large FFT torture test quite happily, yet will fall over on the blend test within a minute or two. I ran memtest86 and it said no errors, is there anything else I could do to check the ram further?

I couldn't find any OCUK profiles, I'm not sure how the OC'd profile is set but at some point it has been reset. It still retains the 182Mhz BCLK but it seems to have lost any voltage settings.

I have found an article on toms hardware that has settings for OCing the i3 530, I will have a play around with them and see if I can get a stable overclock. If not I will chase up the staff :)

Cheers for the advice!
 
Using the Tom's hardware settings it's now been running prime95 for three hours straight without a hitch. Core temps peaked at 69 but have dropped to 63 so a good 10 less that I was getting !

The main difference with these settings is that the ram is only running at 1092 mhz (182x6) compared to the 1456 (182x8) it was running with the original OCUK bios settings. The core running at the same 4004 mhz but with a much slower QPI link speed, the ram voltage is also lower now. Does it matter that the link speed is slower or does it not impact on the cpu output?

The Tom's guide gives stable settings for a 4.2 and 4.4 overclock so will try them out if my cooler will allow it :)
 
Try with 1.35v qpi/vtt voltage

Leave qpi link speed on auto

And set uncore freq to twice what you ram multi is,you can also use normal CPU v,and set dvid voltage to +0.0700v and enable power saving,CPU should downclock at idle and full speed at load

Stress CPU and adjust dvid to raise/lower load CPU v

Can also use 21x CPU multi and disable Intel turbo boost,that might let you run higher ram freq if you pick a higher CPU bclk

Thanks for the info, will have a look into it when I next have a chance to play at burning out my cpu :D
It's all changed since the last chip I overclocked properly was a single core Athlon64!
