GA-EX58-UD3R Motherboard OC Settings Help

paradisiac · 22 Jan 2010 at 19:22

had a quick go at doing an OC, but didnt have time so didnt have too much of a play.
as i know there are a few people on here that use this board, before i delve too deep into it, there are a couple of quick questions.
1. is there any way of locking the ram speed to 1866MHz or will it always adjust with the cpu fsb?
2. what speeds have people got with aircooling?
3. are there any settings i should be aware of that help things

cheers, think thats it.

oh another thing, is it possible to change the multiplier to 21x, and if so, does that mean turbo stops working, or does that then go to 22x?

paradisiac · 23 Jan 2010 at 09:07

anyone?

the_electrician · 23 Jan 2010 at 10:50

the multiplier only goes up to 21x. most people use a multiplier between 19-21x.
you have to disable the turbo manually in bios. This is done to help stability when overclocking. The ram speed can also be manually adjusted.
You should be able to get 4ghz easilly on air.
Try these for starters
CPU Vcore 1.325V
QPI/VTT coltage 1.295v
IOH Core 1.16V
DRAM Voltage 1.640v

and what fsb/multiplier combo?

the_electrician · 23 Jan 2010 at 12:23

multiplier 19x
baseclock 200
= 3.8ghz

20x200=4ghz ect
There has been suggestions that the 20x multiplier is less stable.

CPU Clok ratio 19x
QPI Link speed x36 (7.2GHz)
Baseclock 200
Performance Enhance - standard
XMP disabled
System memory multiplyer SPD - 6.0
Memory frequency - 1200MHz
intel turbo boost - disabled
Cpu cores enabled - all
CPU multithreading - enabled
C1e , C3/c6/c7, thermal, EIST and PROCHOT all disabled
Virtualization - enabled.
Uncore freqency x13 (2600MHz)
Isochronous supprot - enabled
PCI frequency - 100
CIAZ -disabled
CPU clockdrive 800Mv
PIC Express clock drive 900Mc
CPU cliock skew 100ps
IOH clock skew 0ps
DRAM timin schedule selectable - manual
then on all 3 channels set as follows
CAS Latency time 6
tRCD 6
tRP 6
tRAS 19
Command rate 1

Local-line calibration - disabled
CPU Vcore 1.325V
QPI/VTT coltage 1.295v
IOH Core 1.16V
DRAM Voltage 1.640v

everthing else is as at default / auto

Try these for starters for a stable 3.8ghz
You will have to change the ram settings to suit your ram.

my ram is 1866, so should i try to run it at that?

the_electrician · 23 Jan 2010 at 12:31

try a lower freq till u have a stable overclock.

Check out this thread. 3.8 all settings displayed.

ok, off all day tomorrow so might have a play. got a new case coming next week, with 6 12cm fans so hopefully temps wont be an issue.

paradisiac · 24 Jan 2010 at 08:34

well with those settings the pc posted and loaded into windows, will do a quick temp check.

paradisiac · 24 Jan 2010 at 08:35

right im hitting 80 so OCCT fails

will try lowering the vcore?

paradisiac · 24 Jan 2010 at 08:47

had 15mins of OCCT with vcore 1.25 and hitting 79 deg.
will see if i can go lower.

paradisiac · 24 Jan 2010 at 08:49

is there any way of saving the bios as a profile on this board so i can save different setups for quick reload?

paradisiac · 24 Jan 2010 at 09:00

right will i have it running @ 3.7GHz (19x195) vcore 1.20 and its averaging 72 deg under load, peaking at 76 deg, so that will do until i get my new case next week as airflow is very poor in my current one.
cheers for the help

paradisiac · 24 Jan 2010 at 10:33

got it stable at 3.99GHz but the temps are far too high for my liking (88deg) tried to lower the vcore but stability went, so until i get a new case i will settle for 3.7GHz.

prt · 24 Jan 2010 at 17:02

better case with better air flow will help lots. wait till next week before clocking it up more. 88 is a little high me thinks. Got same mobo GA-EX58-UD3R Motherboard it clocks well to about 4.4 is max i got so far.
not messed for a while now

a lot volts for 3.8. my core i7 920 which is not a DO does 1.25 for 3.8

i dropped it down to 1.2 and it was stable, just wasnt happy with temps so dropped to 3.7GHz and its ok, so will wait til the new case comes next week

is there much difference between 3.7-4GHz?

prt · 24 Jan 2010 at 18:29

i running 4.2 24/7 @ 1.295v
tis all water cooled so well cool
