Hey guys I have two issues so please bear with me and read one
I recently built a new pc with a core i7 860 and gigabyte p55ud4 mobo
My problem is that normally my cpu would go down to 1.2 ghz when im doing nothing tasking. But for the past couple days its always been at 2.9ghz.
I had a previous issue where my cpu never went above 2.0 ghz but a quick search on these forums showed another user with a similar problem and it seemed I had to change my multipliers in the mobo to increase it to stock. With that resolved my cpu jumped to 2.9 when I ran games and such and dropped back to 1.2 when I was just browsing or pc was idle.
However recently it has always stayed at 2.9 ghz. This would not be an issue but it feels wrong because I never overclocked and I am afraid Im ruining the cpu.
For the speed locking issue - your computer is not taking advantage of speed step. This could be a BIOS setting, or a Windows setting. Or, given your second issue, a much bigger problem. First, within Windows open Power Options. (Go to Start and type "Power Options" in the Search programs and files box.) Within the power options window, click on "Change plan settings" next to which plan is currently selected. Now click on "Change Advanced Power Settings". In the power options window that opens, look under Processor power management, then under Minimum processor state. This should be set to a low number to enable idling on your computer, a typical value is 5%.
If that is already at 5%, then check your BIOS to make sure EIST is enabled. In Gigabyte's BIOS, go to MB Intelligent Tweaker (M.I.T.), then Advanced Frequency Settings. What is your CPU Clock Ratio set to? It should be set to 21. If it is not, change it to 21. This could be part of your stability problem if it's not 21. Next, from the same menu go into the Advanced CPU Core Features menu. Make sure CPU EIST Function is set to Enabled. If it is Auto or Disabled, change it to Enabled.
Next to your stability question, this is a good time to ask what settings you have changed in BIOS. Taking another look at your screenshot I noticed that your voltage is very low considering your multiplier and speed. What BIOS options have you changed? Also, what version are you running? You may want to upgrade to the latest BIOS, then from the main screen select Load Optimized Defaults. If you do upgrade BIOS, do NOT use the Windows based @BIOS program. Use the QFlash utility from within BIOS.
I'm glad it was the easy solution! When you open Power Options, which plan is selected? My two main plans are Balanced and High Performance. The minimum processor state for Balanced is 5%, while for High Performance it's 100%. So I keep my computer on Balanced the vast majority of the time.
My CPU stays pretty flat at 1.2 when I am doing very little. However, multiple windows open or application like anti-virus software in the background will make it fluctuate. I would suspect yours is fine and you're just seeing the results of other things running.
I often like to quote bilbat, another forum member, who compares using the @BIOS utility to playing russian roulette. Why should you avoid @BIOS? "@BIOS seems to be able to either overwrite or corrupt the BIOS' boot block"
This is a very frequently discussed topic in this forum. I recently encountered a poster who was advising other members to never update their BIOS. Why? Because he had bricked a board. And what method had he used? Yep, @BIOS. Here's a link to one of the more recent discussions on updating BIOS and the perils of @BIOS if you're interested: http://www.tomshardware.com/forum/270171-30-p55m-boot-m...
And since I looked that up, I'll include my typical instructions for updating BIOS with QFlash:
Updating Gigabyte BIOS with the QFlash utility is fairly straightforward.
1. Download the latest BIOS file from Gigabyte's website
2. Run the file (or double-click it), the file is a self-extracting zip file
3. Copy the unpacked contents onto a USB stick
4. With the USB stick plugged into your computer, restart the machine
5. Enter BIOS
6. Enter the QFlash utility (I believe its F8 but it will say on the main BIOS menu)
7. Choose to update BIOS and then select your USB drive, which will be named something like HDD 0-0
8. When done, back in BIOS choose Load Optimized Settings, then set any RAM V if needed, then reboot and re-enter BIOS and configure the rest of your settings
hey, i have an i7 860 and I am having this same problem as well (stuck at 2.9GHZ). It suddenly started to happen after I flashed my BIOS in order to be able to use OC Genie. (MSI themselves told me to do so). But now I can't acces my BIOS! With OC Genie disabled or enabled, it shows a MSI splash screen which I cannot exit. This means I cannot flash my BIOS either. Under advanced power options, I can only select System cooling policy -> active/inactive... so how do I fix this?
What key do you normally press to get into BIOS? The delete key? Just keep trying - before anything even comes up on the monitor. Hit it repeatedly and for various lengths of time until you can get into BIOS. You'll find the right place and time eventually.
thanks for the comment. but wat I did was enable OC Genie, so it showed the startup screen and the white text. I quickly got into BIOS, and disabled fullscreen logo. Then I somehow magically got rid of the 2.9 GHz. And afterwards I OC my 860 to 3.6 GHz! After 5 min of Prime 95 temps havent exceeded 65 C. During gaming, it never exceeds 50 C. Ekoostik, I saw u have a cm hyper 212 plus, so do I. Have you overclocked? If so, what speed and temps?
I OCed a little. Then I went for a stock underclock. I played around with a lot of settings just to see what I could do. Then I got busy and didn't need much more than the boost you can get from a 1 Thread turbo so I'm back at stock again, with an undervolted Vcore. When pushing a mild OC and stock Vcore, I don't think I ever saw my temps go over 55C with an ambient of ~20C and that would have been under Prime95 and Intel Burn Test load testing.
