Windows 7: Lagging Windows clock Not in BIOS

Lagging Windows clock Not in BIOS

Hello all!

I have been experiencing significant Windows clock lag. For 1 minute to pass in Windows ~2-3 minutes pass in real time. I just upgraded my CPU to an AMD A8-7600 and BIOS to 2.4 from 2.1 (ASRock A88XFM2 Extreme 4+) because the previous CPU's (AMD A8-6500) GPU unit died on me (STOP 116 error, Thanks again for the BSOD forum helpers). Checked to see if I have a weak battery - would be strange, since I just bought the motherboard in February. The BIOS clock seems to be running fine. Compared it with realtime and no delays (not even a second) during a 15 minute test.

I have been searching around the net for solutions and found WinTimerTester 1.1.
Ran it and found that my ratio is way off: 1.5-3
Depending on "bcdedit /set useplatformclock true" and HPET enabled/disabled in BIOS.
Also tested the system with DPC Latency Checker and LatencyMon. Both stared out perfectly, but soon started to produce significant errors.

While searching for a solution I realized that my VLC is significantly stuttering, which could also be due to this latency issue. Interestingly MPC-HC does not reproduce this stuttering.

I know that I can force the Windows clock to sync every few minutes - this is what I have enabled now - but this is only an interim solution as video playback is still greatly affected.

Thanks for the help!

When you put in the new cpu did you first thing after that put all the bios settings to defaults, and a cmos battery can be dead at any time. Did you check to make sure your cmos battery was at 3 volts and not just working? Those are things that will screw with the clock it sounds like you have a bigger issue though.

BIOS and pre-boot lagging
While in my BIOS I get alot of lag, it is a mouse controlled BIOS on a custom build less than a year old, its specs can be found under my profile. I have a LinuxMint dual boot and GRUB shows the same amount of lag. I am running my OS off an SSD so I would expect fast boot times like my laptop which...

Laptop BIOS clock running really fast
Hi, Recently I noticed that the clock on my laptop was incorrect. I changed it within Windows several times but it kept going wrong again the next day. I decided to check the clock in the BIOS set up menu and it turns out that the clock is running really fast. I'd say it takes about a second...
