Hey, I have i5 ivy bridge and xfire 6950's

I have a Asrock extream4 board and used the extream tuning unitily and changed the multiplier on the CPU and got the CPU to 4.2 easily without issues. but as this is my first time OC a CPU just wanted to know if just changing the Multipler is ok when overclocking.

Also with the GPU everytime I'm on Catalyst Control Centre and go onto the overdrive part and click accept it disapears and I cant find it untill I restart CCC and then it asks me to accept again. I know MSI afterburner is what I should be using for OCing GPU but it has more sliders than CCC and I kinda like things to be silmpler when it comes to OC'ing =D

By yeah, help here would be great. Thanks
 
Changing the Multiplier whilst OC'ing IB chips is exactly what you're meant to do. If you want to go further than 4.2/4.3 you'll probably have to put the voltage up a bit (I wouldn't suggest using software that auto sets everything for you they usually go pretty vcore heavy and it's just not necessary) It's quite easy to learn to use the bios to OC now adays as well I'd suggest taking a look at a guide or two :)

yeah I've looked at a few guides but got alittle confused. But finding a good guide for Ivy Bridge was proving to be difficuilt

The only reason I haven't done it in the Bios is because my keyboard doesn't work in it :S I have to plug in a different one.

Ah that will be why I got the BSOD at 4.5 =D

though the extream tuning unility changed my Bios settings so it wasn't like CCC where it only oc's when app is running. But I'll try doing it in the Bios later.

Strange. Did you check the for the USB legacy setting? My BWUS works fine in my Asrock BIOS.

I have the corsair K90. also not sure what the USB legacy is. =D

Also do you know what settings in the Bios is for the multiplier. I cant see anywhere in there 'Multiplier' =D

thanks
 
Lol. You have to change the CPU Ratio to ALL then the one below it is the multiplier value should be labeled "All Core". Ahah don't worry about it then I'm sure someone else will tell you what to do to make you're keyboard work in BIOS :p
 
ok I changed the ratio to 43 so it reaches 4200.46mhz. should I change the Voltages or Bus speed? Bus Speed is at 100Mhz and volts 1.088 (Is the highest i've seen it go) =D

Base clock. It use to play a really big part in overclocking but now it's not really used. By default the BIOS should have it set to 100 but since your multi is 43 and your clock speed is 4.2Ghz instead of 4.3Ghz I took a guess that your BCLK is too low. That or you typo'ed :P

Oh yeah that was a typo. I meant to put 42 :D
 
Ahah I see. Just never touch the BCLK and you will be fine. Like I said make sure you're manually putting in the voltage as well auto usually goes pretty voltage heavy. I'd suggest trying 1.1V seeing if you BSOD at all and up by incriments of 0.05V doubt you would have to go past 1.2V for 4.2Ghz though.
 
the voltage keeps changing. shall I just knock 0.05 off a few times?

Or go into the bios and make it 1.2?

Edit. It only reaches 1.92 anyway. Shall I just leave it?
 
go into bios and make it 1.15V run a stress test and see what happens. The reason it changes in CPU-ID and the like is because the CPU does not always use 100% of the voltage available to it.
 
ok, I'll go into bios and do that. BF3 a good enough stress test?? LOL

I tried finding the intel burn test but never managed to find it online anyway. brb :D
 
Just google Intel Burn Test and use one of the links on a site (just make sure its an upstanding site don't want no virus') also get prime95 and BF3 is apparently a pretty good benchmark. A lot of people will run prime/ibt be stable and crash in BF3
 
when i went to change it i got the option of either offset or fixed. which one? also i was able to either add or minus voltage so i need to find out what its currently set at :)
 
Should be Fixed mode. This way you get to choose the voltage you want. (offset confuses me I don't really understand how to use it so I stay away from it xD)
