post #521 of 696
Hi all,

Pretty much a total noob here. Finally got a job (damn recession) so I was able to build a new pc. I'm moving on from an E6600 core 2 duo and I tinkered a little bit with oc'ing it way back but it's been so long and I'm sure stuff has changed.

So anyway, I got myself a z77a gd65 to go with my i5 3570k and 2400mhz ram (hyper x beast). I started off with the oc genie button to see how things go. I'll probably want to do a manual oc (still the best way I assume?) at some point but at the moment I've got a small issue and I wanna try and understand it first before I get my hands dirty. I've been googling around the place but haven't come up with anything yet to sort my problem, so perhaps someone here can point me in the right direction?

With all the oc settings at default (with the oc button pushed for the 1st time) the board does the usual oc to 4.2ghz, however the ram comes up as 2133mhz. It says it's reading the xmp (and correctly sees it as 2400) but it's being adjusted to 2133. I've had a look in cpu-z and it's showing the half of 2133 as expected.

If I change the ram settings to make it run at 2400 it works and comes up in cpu-z as 1200, so all ok there. But the CPU is back down at stock. With the auto oc it seems I can have my cpu at 4.2 or my ram at 2400 but not both?

Any help or advice would be great. I can post settings/ bios screens later this evening when I get home if that'll help...

Thanks all! thumb.gif

For some reason the core speed fluctuates. It shifts between 3999.97 and 4000.03 or thereabouts. Is this normal? I've disabled Speedstep, Turbo and all power saving features in the bios.

The base clock (or BCLK) will naturally fluctuate by minute amounts during usage and is normal. If your total speed is varying by 0.03 MHz total, that means your BCLK itself is changing no more than 0.00075 MHz (since it gets multiplied by 40). I wouldn't worry about it at all.

Nice BIOS setting Rabid1 smile.gif +rep for you mate wink.gif
But when you OC your RAM to 2133MHz why does it use value of 0.85 Volt?? MSI board use to set CPU IO to 1.25 Volt and sometimes 1.05 Volt (default) when we use Auto setting on it. Do you have MSI Control Center screenshot? What does it show? Same 0.85 Volt?
And at CPU Features, you only change Long Duration Maintained to 128 right? And not to change Long Duration Power Limit[W] 77 & Short Duration Power Limit[W] 96.
And that is stable smile.gif I use to set Long Duration Power Limit[W] to +130 and Short Duration Power Limit to +200... like this :




My default Long duration power limit is 95 since it's Sandy Bridge procie with def TDP of 95Watt, and if I use value lower than 130 then it will throttling down clock while I test because when I see CPU package power while stressing is up to 130Watt.
Your setting is new to me ... gonna try it later wink.gif
Btw when we change CPU Adjust Ratio to +40 and beyond it will automatically change Long duration power limit to 200 and Short duration power limit to 250.

I just bought a z77a-g45 board onto which I equipped my 2500k, but for the time being I cannot understand a single thing going on. My previous board (a Z68) had a very different naming scheme for its controls. Anyhow I wish (am supposed) to get a comfortable a 4.7-4.8 Ghz mark with my i5 but as for now I struggle to get to 4.5Ghz lynx stable, besides I encounter throttling of the kind I never encountered before even though I have disabled all power options... As I said this board seems really weird to me, so any pointers I woud really appreciate.

The rest of my system is 8gig corsair RAM @ 1600Mhz (currently running at 1333, 9-9-9-24), corsair H60 cooling and a 70Amp +12v rail PSU (again from corsair), so I don't see why I should be held back.
Thanks smile.gif

Hello
I have a gd55 and just started having a minor issue that I hope someone can give me some advice with. The problem is one of the front panel USB headers stopped seeing any device that is plugged into it. When I plug my iPhone in it shows that it is charging but not connecting. Could this be a bios issue because I haven't updated and on v1.6 or could the header itself be the problem?

Thank you for your help

Ps I should mention that I tried hooking the front USB to another header it worked. It seems to be just the one header that is not working properly.

What case are you using? Are the USB Ports USB3? I have the G43 and there is a problem with the OCGenie and USB3. Might be a problem like that. If it is USB3 try testing the USB3 ports on the back panel and see if they work.

The case is a cooler master haf 912 and its USB 2 that are giving me problems.

Well if all the backports are working and the other USB headers are working then I'd guess it's a faulty USB header. Hope it's just that on not a controller error. Either way I guess it's up to you if it's worth RMAing it. Personally if all the others are still working I'd just leave it. But then again I dunno if I'm completely happy with my board so I might use that as an excuse to trade up.

Thanks for the help. It has apparently decided to start working again so I don't know why it was not wanting to work last night. Again thank you for the help.

Im using the Z77A GD65 motherboard with a i5 3570K and im running 4.9Ghz game stable, that is 5 hours prime95 blend test, all 4 workers succeeded without failing. I will test it further some day, im positive it will manage above 5 hours. Im running 1.4 vcore in bios, and that is around 1.376V during benchmark. I will post my settings soon, for those who are interested. See my sign for cooling. Highest temp was 84C on one core, but mostly around 76-78C on all four cores.

I tried 5Ghz but one worker failed after 45 minutes, and that was with 1.43Vcore in bios. I think I will need around 1.45+ due to the voltage drop to get it 5Ghz game stable. I had it game stable (5 hours prime) at 4.8Ghz with 1.35Vcore (1.33 while full load), so I guess it takes around 0.05V for every 100Mhz increase at those high clocks. The voltage drop is huge on this motherboard, not to mention the lack of offset control.
