UD5 Overclocking

Robert · 1 Nov 2009 at 14:38

Just built my new rig and it's pretty damn nice...

Dominator 1600/6gb
i7 920 D0
UD5

However it doesn't seem to like overclocking. Tried BCLK 180/1.3 vcore and it just don't take it.

Any advice/template settings that I could use without too much fannying around?

My system came supplied from OcUK with OC 3.6 Ghz if want the bios settings for this I can supply?

QPI is the link you're missing, my box (same components) seems to need more on qpi than on vcore at 200x20.

What version is your ram? I'm trying to source some v3.2 dominator to match the current set, if you bought yours recently and it matches this number it's good news for me

so...what settings do I need to change and to what?

Essexraptor · 1 Nov 2009 at 17:37

check the threads ... 1 guy shows the settings for 3.8 Ghz settings (screen shots)..

Tried the settings in the above post and it just won't work.

It just goes into a reboot cycle

What BIOS are you on?

bluemax · 1 Nov 2009 at 18:22

what memory speed are you running? what cpu vcore are you? what qpi link speed are you? what qpi volt are you? can you take any screen shots of your bios?

Robert · 1 Nov 2009 at 18:24

I'm using the settings visible in the above post and the above PDF - nothing different.

Bios is F7.

RAM is Dominator 1600mhz (3*2)

Are you manually setting RAM timings or using XMP Profile?

Robert · 1 Nov 2009 at 18:30

I left them on auto

bluemax · 1 Nov 2009 at 18:33

i know your mem is 1600 but what is it running at mo!
Firstly change your uncore mulit.what ever your mem multi is your uncore has to be 2x +1 e.g.(mem=8x so uncore =17x)

bluemax · 1 Nov 2009 at 18:33

change you mem timmings! manualy!

Robert · 1 Nov 2009 at 18:34

I have changed the uncore as per the two guides above...

This is really ******* me off now.

Why and what to? They appear to be default...I wouldn't have thought that would prevent me from doing anything or would it?

bluemax · 1 Nov 2009 at 18:36

yes because it make's your system stable!

bluemax · 1 Nov 2009 at 18:37

2nd'ly change your performance enhance to turbo.

Robert · 1 Nov 2009 at 18:38

Well what do I change them to? You can't just tell me to change my timings and leave it there!

surge · 1 Nov 2009 at 18:39

Try
QPI Link x36
Uncore x 18
Isochronous enable

XMP disable (if you have that option)
Memory multiplier x 8

Set RAM timings manually to 9 9 9 24 1T (I'm sure your RAM will do tighter than that, but it should be a safe start)
DRAM Voltage 1.64
