Stutter problem that I can't get rid of. Please help.

post #1 of 22
Thread Starter 
The problem is more of a micro stutter but I'm only using one GPU and it happens in many games and benchmarks. Online players skip around, animations are choppy and it looks like frames are being skipped. 120fps looks like 40 fps. This can be felt with mouse movement as well. The system is in my sig and is running at 3.5GHz.

Example with the vantage CPU test showing the planes skip around and even rewind for a split second: I used afterburner to record this and it only lowered the score, it didn't add any extra stutter.





Edit, another video to show what it looks like during the beginning of the first GPU test. The second GPU test stutters as well, the sides of the large ship jiggle at times. The microstutter shows up as large skips in the recording.





A second but probably related problem is short pauses in the game when playing online. The net graph in games shows what looks like a network problem but my ISP has come out to my house many times to test the lines. I have bypassed the router and tried a new modem and these pauses do not change. Valve had me change all of the network settings and then install a program called Vtrace to see if any programs or drivers could be causing this but they couldn't find anything. Valve's conclusion was that something was wrong with my network and not with my PC. Both of these problems happen in windows 8 and vista.

Example of the pauses and gaps in the network graph:





To troubleshoot my GPU,

I RMA'd it through MSI and the replacement changed nothing. I got a third GTX 460, this time from ASUS, again nothing changed. All three of these GTX 460s passed all benchmarks, EVGA oc scanner and OCCT artifact scanner. I tried using the second PCIE slot but again nothing changed. I also went out and purchased a Gigabyte 7850 but it still showed this weird stutter. Both problems exist with my older 60Hz monitor with a replacement dual DVI cable.

To troubleshoot my processor, ram and motherboard

I ran prime95 blend for almost 19 hours, long enough to pass all of the tests with 90% memory usage and no errors were found. I passed 10 runs of IBT at max without an error. It passed OCCT's 1 hour test. I also left the PC to fold overnight but it was still happily folding on a second work unit when I got up. Overnight memtest86+ AND memtest86 came back with no errors. I ran HCI memtest to 1000% without errors. I also made sure to test the stutter problem with everything running stock by loading optimized defaults but that didn't help. I also tried a second memory kit from OCZ that also passes these tests but the stutter was still there. The highest temperature was 61c and that was during IBT.

I flashed to different bios versions including the latest beta bios for my motherboard. I tried disabling all power saving features in the bios.

To troubleshoot my hard drive

The hard drive is currently running in AHCI mode but I have also tried IDE mode. I have also tried using the Microsoft AHCI drivers and the Intel drivers but there isn't a difference between them. Iran the Western Digital advanced diagnostics twice and neither showed any errors. The smart data is also all OK without any warnings. I also replaced sata cables and swapped to alternative sata ports.

To troubleshoot my power supply

I replaced my XFX 650w XXX power supply with the Seasonic platinum 660XP but nothing changed.

To troubleshoot my network

I mentioned this above but ill add it here too. I had my ISP come out and test my lines and they said everything was fine. I bypassed all cable splitters. I bypassed my router and tried a new modem with replacement ethernet cords but the problem remained. I installed an Intel PCI network card in case my motherboards port was failing but yet again, nothing was changed. I even tried using a wireless USB adapter.

To troubleshoot the OS and drivers

I tried the default windows update drivers for my network adapter as well as the newest available from Realtek. I tried clean installing many whql Nvidia drivers in vista and windows 8. I tried reformatting and installing chipset drivers as well as reformatting again without installing chipset drivers. I have tried enabling and disabling HPET in both the bios and windows. With windows using HPET 64 bit the DPC latency is very low. I have 8 tabs open in Firefox, one of them is a 1080p youtube video playing and another one is pandora playing music and the DPC latency is 5-15 in LatencyMon.

To troubleshoot audio

I pulled my sound card out and removed the drivers. I made sure the integrated sound card was disabled in the bios and drivers for it were never installed. Both problems remained without sound.

What's left to troubleshoot? Did I overlook something?

The only hardware that hasn't been swapped out is the CPU, motherboard and the hard drive. Maybe my ISP is lying about my lines being problem free?

I have a 120GB Samsung 840 SSD coming next week but since no errors were found with my current drive I doubt the SSD will fix my problems.

Could the CPU or motherboard be causing this problem but still pass every stress test that I throw at it? Unfortunately I can't find any cheap X58 boards to buy. The benchmark scores seem to be normal and where they should be.

CPU is at 3507 MHz and the ram is at 1336 MHz.

Cinebench 10 = 20264 multithread and 4938 single thread.
Cinebench 11.5 = 6.02 multithread and 1.19 singe thread.

The frustrating thing is that this PC hasn't blue screened or frozen since I have been experiencing these problems. Zero WHEA errors as well. I just don't get it. Please help before I just give up and find a new hobby.

Bump.

Not to be that guy but have you tried reinstalling and formatting but using Windows 7 rather than the not so liked win 8?

Aside from that looks like you've ruled out everything save mobo having a weird random issue that only can be perceived in game stutter and not benchmark scores.

I don't have windows 7 but these problems were still happening in a fresh install of windows vista 64 bit so I don't think the operating system is to blame.

I had a simalur issue ... was about three years back, i ended up buying a new mobo and a new cpu and it fixed the problem ... memory or cpu clock problem or something but I found it better to get rid of the issue and the head ache biggrin.gif


EDIT:

Same CPU you have biggrin.gif I went to a 2500k wink.gif

Sorry to hear that you went through a similar nightmare. I don't want to scrap this old rig just yet though because the CPU performance is more than I need. Maybe when haswell lands.

I just don't understand how the cpu or motherboard can cause this but still pass all stress tests. If you had to guess between the two, would it be the motherboard at fault?

I have a i7 2600 and i get this from time to time i just reboot and it normally fixes it for me

The SSD came in and it didn't solve the problem. So I'm down to just the motherboard and CPU that haven't been swapped out but they can pass all stress tests.... madsmiley.png

Stress tests only fail when you have corrupt data. If the CPU/MoBo is still processing correctly, but doing it slowly, then a stress test won't show a problem. It seriously looks like a problem with the processor, and I'd go ahead and replace both the processor and board at the same time.

Processors have failsafes built in to detect problems that may occur with age, and when those problems occur they correct the error before passing the processed data on. When this happens it slows everything down greatly, but Intel considers it a benefit since the chip is, after all, still working correctly.

Wouldn't that cause benchmark numbers to be lower then? From what I can google, my CPU is scoring what it should be at its clock speed.
