P67-C45 overclocking oddity?

Running an i5 2500K on this motherboard with 8 gigs of G. Skill sniper ram (9-9-9-24 @ 1600Mhz 1.5v, but motherboard is running it at 9-9-9-24 @ 1333Mhz 1.38v which results in better perfromance in IBT at least). Bios updated to 1.7 (7673v17).
In the bios I've adjusted the core to 45x, and set the V core to 1.285 manually. CPU-Z shows the vcore jumps up to a max of 1.31 at full load under a stress test. I assume this is because of PLL? The margin seems small enough it's probably safe to leave it, but figure I'll check for feedback as this is my first OC I didn't just give up on.
Also in the bios however, under Core Ratio, it shows 'locked'. CPU-Z and realtemp show the overclocked speed. It never steps down even though turboboost is enabled in EFI. However windows 7 x64, prime95, and GPU benchmarks such as FFIV Benchmark show the CPU as only @3.3Ghz. Is this a display error from EFI or is it just pulling standard info about the SKU and not showing the actual clock?
Based on the gflop and speed in IBT, it LOOKS like it is overclocked (higher clocks from the bios results in higher gflops as long as the voltage and ram stays in a good range), but I'm unaware of any form of game benchmark that I might try to figure out where the error is, as these usually show the OC'd speed. Without any OC, CPU-Z properly bounces between 1.6 Ghz and the 3.3 Ghz on load. I've tried it with both CPU-Z 1.65, and 1.65.2 which is updated specifically for Sandy Bridge support and get the same results.
That's the results of the OC. IBT shows the overclock does seem to be in effect. CPU-Z's stats are 'at idle' however.
Basically: Is there something I've done wrong with the OC that is causing other things to not show the OC? Is there a reason the CPU isn't switching between idle and 'turboed'?
As a footnote, the bios beeps, I'm unsure how to fix 99 and A2 error codes. I fixed the IDE channel one by changing SATA mode to ACHI (which works better for my SSD anyway), but those two I can't seem to solve. It seems to be a result of the EFI change and the bios can't check the things it usually does.
Let me know if there is more information I should include.

Did some poking around and it turns out I was overclocking the base instead of the turbo, and that the random BSODs I was having when the system was 'idle', or just browsing or whatever, was a result of the bios dropping down the vcore due to the processor not doing anything.
Also, by overclocking the turbo it now properly ramps up in CPU-Z, though it has to be an application which taxes it enough to make it want to ramp up first.
Anyone know of a C-State setting I could use to tell the system to go 'full sail' when I do more than just browse the internet and watch a video? I'd prefer to keep the power savings there but only if I can get it to play nice.
Don't suppose I could maybe get a link to the BIOS number codes by Jack or someone? :p
Keep getting 98 99 A2, and I think in one case it's due to my keyboard not being fully supported by the bios (It sometimes doesn't activate on a boot).

R9 290 Black screen with p67-c45 b3

Hi i have p67 c45 b3 1.j version and i have bought a r9 290 but when i turn on the pc i receive black screen " no signal " from the tv...
i saw that probably is a problem about Bios, it is possible?

Even if you don't have an IvyBridge CPU, for R9-290 you need a 5.X BIOS:

Be aware: the BIOS update from 1.X to 5.X is problematic (for your Core i5 2500K)!

MOVED: P67-GD65 Overclocking

Overclocking is at your own risk.
A moderate overclock could be regarded as a set up where you can maintain your power saving features and keep your voltages within the Intel specified values. For the Sandy Bridge CPUs it is recommended to stay below 1,4V.
OC Genie normally provides higher voltages than is really necessary and if you start tweaking yourself you may find for the same voltage, that you probably run at 4,3-4,5GHz. But each CPU is slightly different and you will need to find the upper limit.

P67-GD65 Overclocking

indeed, same with overclocking tbh, never tried it, always been scared of doing overclocking and it invalidates ur warranty with the chip hence i never do it, u think its worth overclocking my 2600k or not, main thing i do is game on it, whats with the oc genie stuff i hear about on the board, think i pressed that and it went to 4.2ghz with a core volt of about 1.35v, is it worth keeping that up and is that voltage save and will it do harm to the chip?
currently it bounces between 1.5ghz and stock speed @1.16v

P67A-C45 (B3) impossible to boot after BIOS

Hi !
I've just assembled my new config and I experience some boot problems:
MSI P67-C45 (B3)
Intel I5 2400S
GSkill 2x4Go Ripjaws
HIS Radeon 6670
Seasonic XSeries Fanless 400W
After assembling, I powered it on for the first time, reached the BIOS succesfully then tried to install an OS from CD and it is impossible to boot it. I tried from several CDs ans USB key without success. From the F11 boot menu, I tried to choose the CD/DVD or the key, without success. Each time the power turned off and the PC rebooted. Everything component seems well detected in the BIOS, CPU is listed, SATA components too...
I checked everything without success... There is one thing that I don't know about is the active phase switching leds. In the MB manual, there are 2 situations listed: OOOX and OOOO but I get another situation as soon as the power is on. The first led is goes on instantly and then the third and fourth so I have the configuration OXOO. I searched the MSI site and the Internet but didn't find if this is a sign of troubleshooting.
Thanks for your help !

On all my mainboards in the 6 series, all the LEDs are lit when in the UEFI/BIOS. This could possibly indicate pin/CPU contact problems in the CPU socket, but not positive of that.
Thx, that's exactly what I was thinking in the first place. One more question, in that case, would it be possible that the BIOS is working just fine with CPU detected ? Because I have no problem in the BIOS, the CPU is well detected, I just can't boot after it... In one hand, BIOS makes me think CPU is OK, in the other hand, the leds make me think something's wrong...

Something weird with the keyboard

Hello everyone, i have this strange problem with my wireless keyboard. Everytime i type down a letter, it appears down as many times as i hold the button. Every letter, except X. It is the only letter that i can only type one time, even if i hold it down for several seconds. I don't think there is something wrong with the keyboard or the specific number, because when I hit it again and again the letter appears. Only when i hold it down it only appears once. I know this is not something to bother about, since i can type the letter, but i am curious to find out why this happens. If anyone could tell me, please, do not hesitate

Quote from: sjay on 18-April-11, 04:52:57
This is due to the manufacturing of the keyboard itself. The way its setup is that the keys that are giving problems are obviously located on a different chip and are being recognized as a different device, therefor fail to start or function at all in lowlevel driver enviroment.
There are threads all over the internet about how these expensive keyboards are causing problems with Win7 because of how they are made. Just don't buy too expensive of a keyboard that has a bunch of extra things because those "extra things" are handled differently then a typical keyboard, which is counted as one device. My Saitek red Eclipse works perfectly fine, though it doesn't have extra programmable macro buttons or anything (and thats why it works). It does have volume + -, mute, and backlight adjustment buttons though.
Surely that cannot be the case. This keyboard works fine with every other motherboard including the lower-end P67S-C45 that I have sitting next to me. Also, lets not confuse the issue, this problem does not affect Windows.

SATA Ports 3, 4, 5 and 6 'Not Present'

yeah, basically the title
Had this P67-C45 since February, with an HDD and DVD in SATA ports 1 and 2 - chucked an SSD in recently on the cable the DVD had been using no problems
new SATA cable arrived for the DVD drive today - plugged it into ports 3, 5 and 6 with no result
in the BIOS all four SATA II ports are marked as 'Not Present'
something is wrong with that
please help

Quote from: ParaDismal on 03-December-11, 02:36:45
B2, but I doubt it's the cougar point issue because these ports have only seen a month or so of use back when I first built the PC and I ran an HDD health test not long before I stopped using them and it came out fine and dandy
If the SATA II controller is enabled in the UEFI/BIOS, then it 'is' a chipset issue. Recommend the mainboard be replaced with a B3. It is possible you may be able to migrate your OS HDD without having to do a fresh install. Depending on your location, a cross ship may be possible that would minimize the down time.

Turbo Overclock with MSI P67-GD55

Hey,
I'm trying to overclock my 2500K, but I don't want it to run always on the OC Clockrate. Now I read it should be possible to change the Turbo Multiplier so the OC only applies when heavy CPU Power is needed. When I check my BIOS and go to Overclock>CPU Features. There I find: core 0 on 37x,1 on 36x, 35x,34. But the problem is, that I can't change these values. Is this locked at the GD55 Motherboard?
System specs:
Latest BIOS version
Intel Core i5 2500K
MSI P67-GD55
4 GB RAM Kingston HyperX 1600Mhz
Samsung Spinpoint F3
Nvidia GTX275

Please read this article to better understand the turbo boost technology. http://www.legitreviews.com/article/1501/2/
The technology applies max turbo boost to 3,7GHz only on lighter loads, i.e. when one core is being used. As sson as more than one core is under load the turbo boost will reduce until under full load the processor will only run at 3,4GHz. This ensures smooth transitioning between loads and a better performance under loads. There is no reason to disable this.
Furthermore, you will find when your PC idles, the clock frequency will actually go down to 1,6GHz or there abouts to conserve energy and reduce heat generation. Under light loads the Processor may run anywhere in between the minimum and maximum defined Intel clock frequencies.
If you were to increase your CPU multiplier to say 40 and leave everything else alone, then the maximum core clock applied will be 4,0GHz, but the PC will still reduce back to idle when there is no load. Give that a try and observe the behaviour. Download CPU-Z to monitor the voltages and frequencies.

MSI P67-GD65 + 3770K overclocking

Hi,
I've used my P67-GD65 for almost 2years now in combination with an Intel Core i7 2600K and I was able to overclock just fine. Ever since I flashed my GD65 to v4.1 and v4.2 to support my new 3770K I can't overclock anymore (aside from Intel's default turbo of upto 39x). Also ECO mode and OC Genie mode are unresponsive in the BIOS.
Does Anyone know how to fix this?
Thanks for reading,
-Blade-

I copied the bios of a forum member that's able to OC his 3770K on his P67 GD55 and I'm stll not able to... It showed him having 45x 100MHz but it only applies 3497MHz for me

P67-GD65, change Turbo multipliers in BIOS for overclocking

Hi,
Here are my specs
Intel Core i5 2500k
MSI P67-GD65 B3, Bios 1E
8GB Corsair ram
I have read a lot on guides and other forums on how it is possible to keep the base multiplier, i.e. at 33 and to go into the CPU features part in the Overclock menu and change the core limit for Turbo multipliers so that the over clock comes into effect when turbo kicks in. As yet, though I haven't been able to pull it off. I have changed the multipliers and increased the watts given in the menu. But still in windows the CPU only goes up to 34 multiplier. Even when I set the multipliers to a relatively tame 40.
Am I missing something here. Is this sort of thing not possible in the new BIOS, because all the guides and topics have referee to old or beta BIOS. Bt I don't want to start flashing them all and screw something up.
So any help will be appreciated. Thanks in advance

http://forums.overclockersclub.com/index.php?showtopic=183670
Please check down below where he shows how he over clocked using turbo, "Latest Successful Attempts using Speedstep Turbo overclocking"
That's basically what I am aiming for. I will be over clocking through the BIOS, I want to leave the base multiplier at 33 which is default for my processor and over clock by changing the turbo multipliers.
I have tried an older BIOS, 1.9. In it using the instructions provided I have been able to do what he mentioned and with prime95 my clock speed runs at 40x.
I'm trying each BIOS to see which one essentially killed this feature. Because in later BIOS this doesn't work and for some reason the turbo multiplier cap seems to be fixed at 60.
A review by Guru3D mentioned a similar way to overclock the board

Overclock P67 Asus - Sandy Bridge

I am trying to overclock my new Sandy Bridge System.
uname : 2.6.37-ARCH #1 SMP x86_64 Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz
mboard : ASUS P8 P67 EVO
In the uefi-bios if one chooses the performance-profile the system should automatically run with appr. 4.5 GHz in turbo-mode after save/reboot.
Stress-testing my system (kernel-compilation, multiple WinXP-vms) all cores show the regular frequency of 3.4 GHz:
cat /proc/cpuinfo =>
cpu MHz : 3435.835 (for all 8 threads)
Are there any tools that correctly monitor cpu-frequency?
What's weird is that my VirtualBox WinXP-images running cpu-z also show the base frequency even under 100% cpu-load, so no turbo-boost here.
Manually overclocking in the bios yields the same lame results.
Any hints are welcome.

The multiplier never exceeds 34x while monitoring with i7z-svn.
Compiling thunderbird-branded from aur I get the following output:

That's it, it never goes over 34.00x. What could be the reason for this?

P67-G45 won't overclock

Hello. I have a P67-G45 that I bought several years ago. Lately, I have been trying to overclock my CPU to about 4.2 ghz or so. Being new to overclocking, I made many mistakes at first, but I think that I have the hang of it now. I set the CPU Ratio to 42 in my BIOS and set the voltage to 1.3. After tweaking a few other things according to a tutorial on an overclocking forum, I restarted my system and opened CPU-Z, RealTemp, and Prime95 to test it. However, when I run a Prime95 test, for some reason my CPU ratio will not go above 3.9. When not running Prime95, it breifly can go to 4.0 or even 4.1 sometimes before going back down to an idle 1.6 or so. What is going on? According to the control center, everything is set to 4.2 (well, 42 I guess), but the multiplier is staying at 39 maximum when running a stress test. You can read this thread over on another forum with full details of my overclocking experience thus far here :http://www.overclock.net/t/1542410/overclock-i7-2600k

It's common to suggest to upgrade BIOS. I recommend not to unless it is essential, and reading the comments on manufacturer site do no harm either.
There are two ways to OC SandyBridge and above CPUs, one is change the clock, and the other is change Turbo settings, so lets try that way.
Load optimized defaults, change vcore as before then set all cores boost ratio (in CPU Features) to 42 (Turbo must be enabled). On my board is enough if I set 4 cores to 42 but would be safer to begin with all of them at 42.
Try with OverSpeed Protection disabled, or enabled and power limits 130 for short and 120 for long.
My CPU runs 4 threads of Prime95 (v28.5 AVX) at about 100W at 4.2GHz. So maybe for testing only, disable hyper-threading.
Another thing may be insufficient vcore maybe? Not sure what safe vcore is for 2600k, so look it up before increasing.
Ok, I tried this all and still got the same results. I enabled Turbo, then changed all the values that you suggested with the ratio at 42 and vcore at 1.3. When running 8 test threads in prime95 I still only get up to 3.9. I tried again, enabling enhanced turbo, but it didn't change anything. The only thing that I did not try was disabling overspeed protection, and I'll try that now, but if it doesn't, what is going on?
