Gigabyte EX58-UD5/Extreme Discussion Thread

[SteveRo]

technut36 I Tried X16 and X17 also timings a 8,8,8,24 and 9,9,9,27 - no combination worked Any other ideas? I know I shoul dbe happy with the overclock I have got but it annoys me that my memory is running under it's rated speed

Oh and I haven't been called 'young' for many years

2gb modules have been a problem for some folks when ocing.
You may need gobs of v.
For example my pi 2k memory - when I turn on xmp - it sets the qpi v to 1.555v!!!

Barring adding lots of voltage, send a complete list of your settings, v's, multi's, bclock, ... and lets see if anything looks unusual.

Ok Here goes

F6a
20x190 Turbo enabled
QPI x36 = 6.84GHz
Uncore Auto = 3800MHz
Isochronous support enabled
performance enhance STD
Multiplier 6 = 1140MHz
DRAM timing Auto - this shows 7,7,7,20,1T in BIOS
CPU-Z shows FSB : DRAM 2:6 8,8,8,22,1T
LLC Disabled
VCore - 1.425
QPI 1.395
IOH 1.100 AUTO
DRAM 1.5v AUTO
QPI Pll 1.14v
Dram termination 0.75v AUTO
CH A,B,C Data V Ref 0.75v AUTO
Ch A,B,C Address ref 0.75v AUTO

Tried to manually set Dram Volts to 1.64 and timings to 8,8,8,24 which is where the memory (OCZ Gold 1600MHz) was rated for 1600MHz operation, left everything else the same. This didn't work so tried Uncore at 17x and 16x as you suggested, neither worked

So with turbo enabled your actually getting 21x190?
qpi and uncore look fine, you could actually lower your uncore some I think down to x13 even.
Running things on auto is sometimes not a good thing in that you end up letting the mobo bios decide important things for you.

You might want to learn your default v's and set them manually, same with your qpi and uncore multi's and also your memory multi and timings.
That way you're not guessing at what the mobo set them to - you know because you set them yourself

LLC should be enbled - it is supposed to help keep v's level under load.
I keep qpi v no greater than 1.335 unless ocing.
You could run your mem volts higher, the intel max is 1.65 - perhaps even as high as 1.875v.
One rule that many of us have used is to keep the mem voltage no greater than .5 v higher than the qpi.
So for example - if you set your qpi to 1.335, you could set you mem voltage as high as 1.835v.
This is what has worked for me but as always - YMMV.
Other max v's below.

yo SteveRo im always learning with you What does YMMV mean?

Your Mileage May Vary.

Hi , looking at these boards the UD5 verses the extreme that is , as i am about to take the plunge into i7, just wanted to ask if the extreme version of this board is likely to achieve better memory speeds or better overclocks , thanks

SteveRO - Yes I'm running 20x190 with Turbo enabled. I Had to increase the voltage for qpi (1.335 up to 1.38) when I moved from F5g to F6a. It did fix the double post issue however.
I've been on to OCZ and am going to RMA the memory. I'll try following your suggestions when I get my replacement memory next week, thanks for the input

can i get some advice from you gigabyte ex58 guys?

Hi bacon612

I got the same RAM and CPU but the UD5 mobo. I've got 3.99GHz 21x190although had some problems with the RAM as I couldn't get it to run at 8x190. Saying that OCZ have been excellent - I spent 45 mins on their forum and they organised RMA for me so I'm sending it back after the weekend. There are plenty of people here willing to help you - I lurked for ages and played with my settings before coming and asking for help. BTW I upgraded from a Barton 3000+ so it had been a while for me also!

I've just gone to F5 final from F6a and I'm also needing lower voltages for the same overclock.
