Z68 Extreme4 Gen3

Hi all,

I've noticed on a few occasions now that my BIOS is missing some settings on my Asrock Extreme4 Gen3 with i5 2500k.





I believe there should be 'GTT Frequency' and 'Voltage Override' under my 'Internal PLL Overvoltage' setting but they dont appear?

Does anything else look missing / not right to anybody, as i cant get it to post passed 4.4ghz..

Thanks,

Pes x

On a side note here's a nice new grainy picture of my board :)

Zoomee, what is the actual Vcore you are having at load with this setting? Can you use AXTU or HWinfo for the reading?

hey mate. Sorry but I dropped watercooling over the weekend and went back to air. I found the following volts were required 4.6 = 1.28v, 4.8 = 1.32v, 5.0Ghz = 1.41v

Now the problem is with temps - even with watercooling I was struggling keeping the temps under 80degrees C when under load (due to having 2 x 5850's in the loop too).

The extra voltage and heat would just degrade the chip quicker so I went back to 4.6 which is easily acheivable. I also noticed at 4.6 I don't need PLL overvoltage and don't get any of the stupid dual -power ups etc. 4.6 is easily achievable on air without pushing limits ;)
 
Seems like Im getting there.
Testing 4.8 at the moment with temps for LinX hitting 72C max. Not bad with a 1.4 Vcore.
I cant believe how low you need to set your vcore to achieve 4.8! is this the fixed setting?
Can you check this while running LinX for me with HWInfo? Im interested in seeing the max value after you start LinX (all mem) and what is it in current value.
 
Hi guys just built my new PC, I was wondering which method is best for updating the bios. There seems to be Instant Flash, DOS and Windows.

Also would using a usb key be best?

Thanks!
 
Got mine up and running Friday night.
Saturday afternoon was spent figuring out why my internet speeds when downloading were jumping around and connection was getting lost at times; eventually took the LAN driver off and reinstalled it straight from the MoBo disk without going through the disk control panel. Seems ok now.
Sunday was spent trying to figure why in 50% of boot ups the sound on my usb sennheiser headphones was messed up, same again, took the usb drivers off but this time let windows 7 put generic drivers on, works fine now but haven't tried the usb 3 ports as I read they are not backwords compatible (they are meant to be) and have no usb devices.

I now have two USB items in device manager without drivers, but I'll look at that later as its running ok without them and I want to make sure that I have the headphone issue stable for a week before I go messing with drivers again.

My verdict on the board:
Looks very nice
I expected a bit better out of the box running and think the fast usb, and fast lan tech caused me issues so would advice not to put them on unless you have tested everything without them first so you know basic functions are working ok.
OC support is superb.
Fast boot is amazing.
No pre-windows startup internet access, loved this on my ASUS.... very handy if things went wrong.
My SSD boot drive seems to be faster even tho I put it on a SATA 2 port, will test it soon to see


All in all I'm happy with the board and will think about upgrading to Ivy Bridge with this board if it turns out to be any good.
 
Guys quick question im planning on buying this board in a couple of weeks and waiting for the next gen graphics cards. I also plan to Sli the next gen when its released will the 8 x 8 x sli rather than 16 x 16 x of more expensive boards make much of a difference when these cards come out?

1 or 2 fps tops mate. A negligable difference ;)

about 1.42volts mate, now that I've got it settled again. Looks like I had to up the Turbo voltage to +0.050 aswell!.

I will honestly say though these boards are very unstable to super high overclocks i.e. 4.8 or 5.0 ghz. If your just after a (very good at that) 4.6Ghz you won't have any problems. Anything higher and you have to get into fine tuning and even then it can be troublesome. they are still new boards yet so I'm cutting ASRock some slack here and giving them a chance to update a couple more BIOS revisions. Seems they are too busy giving the P67 users all the love that we Z68 users ain't had a BIOS revision since back in september :(

I've got my chip finally stable again at 5Ghz @ 1.41 to 1.42v BUT I keep getting that stupid boot loop (PC reboots about three times on startup or restart) which is beginning to get VERY irratating, especially when the missus has been on my PC and doesn't know whats going on :mad:

I don't have any issues at all @ 4.6Ghz - just when I go higher to 4.8 or 5.0 :(
 
Hi all, I am building my first rig with this mobo, and I'm looking to connect 4 120 mm fans.

Can anyone confirm if this is possible to do so on this board or would I need to connect some extra to the PSU?

If so, can someone link me to cables I might need. Much appreciated

2 by the CPU (CPU 1 and 2) - 1 by the ATX connector and 1 by the SATA ports - thats four. And then theres two left in the middle of the mainboard too ;)

Thank you very much for the quick reply.

Forgive my noob status but would this still apply if I used the Antec Kúhler H2O 620 CPU Watercooler?

Edit - (read your post again, nvm!)
 
I made a post on another forum but thought someone from here might be able to help me also.

So I had a go at overclocking and manually tried using some basic settings for 4.5Ghz and when I applied the overclock my pc restarted but wouldnt boot and had the error code 71 which in the manual says "South Bridge DXE SMM Initialisation is started".

I hit the clear cmos button and then tried the auto overclock feature to 4.6Ghz and again applied changes and the same result happened, error 71.

So I tried once more and did the overclock feature to 4.4Ghz and this time it booted and ran an intel burn test for 5 runs and all seems well.

So any ideas why it wont let me go above this?
