Poor performance after cold boot

So basically, I just upgraded from a GTX 670 to an R9 290.

The only problem is that after a cold boot, I get very poor performance in 3d applications. I've tested it in dark souls ii and unigine heaven.

The problem actually started while I was still using the 670, a few days after upgrading my case (to a 750d, about a week and a half ago).
I was getting the same poor performance after a cold boot and also driver crashes and one bsod. I tried updating the drivers and re-seating the card.
After re-seating there was one driver crash but then it ran heaven overnight without any problems. I thought the 670 was faulty but now I'm not so sure.

I was planning to upgrade to a 290 anyway and the nvidia drivers were properly removed when I upgraded.
I'm not getting driver crashes or bsods with the 290 but still low frame rates after a cold boot. Latest stable driver (14.4).
The game-play in dark souls ii feels very choppy and the scores in heaven are significantly lower. Once I reboot the problems go away. I'm using custom settings rather than a preset so the scores may look weird.

Any suggestions / help / input would be appreciated.
 
agreed with usb to ssd clean installs of 8.1 are about 10 min now....would definitely cut down a lot of troubleshooting time with weird issues like that
 
Failed hard drive? Or failing, could be a buffering loading issue not related to the cards since you have changed them and have the same problem. Another option would be running memtest on the machine to rule out memory issues
 
Thanks for the suggestions, re install seems to have fixed it.

Edit: Nope, now getting about 2-3 fps in heaven after a cold boot. Also it sometimes takes a couple of attempts to post from cold. After the reinstall the first post and windows boot were very slow and bios screen was a mess (not artifacting like a gpu failure but text was in the wrong place, parts of the screen overlapped each other and were swapped round).

Then you're left with the following. Troubleshoot BIOS/UEFI/Video BIOS, rebuild your system in this new case you just got, replace hardware.
 
I'm going to run memtest tonight but I'm leaning towards a faulty motherboard.
The only other board I've had that became laggy when in the bios was a 680i board, it died pretty soon after.

I've been on the current, latest uefi version for months but the problems started less than two weeks ago and I hadn't changed any settings.
Earlier today I cleared cmos settings and this also fixed the problem temporarily, now it's back, without changing any settings.

power supply?

Don't think so, it's only about a year old and has been rock solid so far. Also I'm not getting any random shutdowns under load etc.

Please could a mod move this to the motherboards section? I think that may be the best place for it. Thanks for your help / suggestions here.
 
have you fix this? i have exctly the same issue wioth my gigabyte z97x gamign 5, with sapphire r290 tri-X, corsair 8gb vengeance 1600 ,always slow fps in cold boot, and i need to restart always....this is shit,,,, i will change motherboard....and if it still not fixed change to nvidia gpu and ram....deserate with weird issue like this...
 
I contacted gigabyte and explained the problem, they sent me a newer bios version.
After flashing the problem was fixed.

I'm not 100% sure that is was the bios, I had previously manually set bclk to 100 and I think this may be the cause.
Since flashing I have left bclk on auto and not experienced this issue again.
 
you got gigabyte mb? , could you tell me model? , i am thinking to email gigabyte too
 
pci-e it confiogured in gen3...anyway soeed is changing dynamicall from 1x to 16x
 
lol guys you are right its something about pci express.... i disable something called DMI gen2 speed to disable and now it take only 15 second from cold boot and no low fps. thx ...the bad thing i already ordered msi z97 gaming 7

Thanks for sharing fix, this is a problem I'd not heard of yet.

A quick google search shows "dmi gen2" to be a bios option. So, when you turn your computer on, press the button for bios setup (typically like DEL or F1, etc.) DMI Gen2 setting is under the "Miscellaneous" tab. Change, save and exit
 
My motherboard is a z97-ar, CPU is i7 4790k, and GPU is Asus Geforce gtx 760 (sorry should've post this in the first place). But I am still unable to find DMI Gen 2 or the "Miscellaneous" tab anywhere in the bios settings. ><
 
I found the settings and disable DMI gen 2 speed but the problem is still here (low fps in game and everything else even dragging application windows around on the desktop there's a delay), and with a restart everything is smooth again. Should I change my PCI express settings to gen 3 instead of auto? Also when I shut down the computer there's an error message pops up: "the application was unable to start correctly 0xc0000142". So I'm thinking the whole problem has something to do with nvidia drivers 344.75 which is the latest version. Any constructive thoughts would be really appreciated. Thanks! ><
 
Did you managed to resolve it? Im having exactly same issue (using R9 285 and latest drivers). Tried all suggested fixes and no luck so far.
 
What I tried so far:
- set pcie bus interface from "Auto" to "3.0"
- windows power plan set to high performance
- unparked all CPU cores (Clicky)
- enabled Overdrive in GPU drivers and set power slider to +20
- tried DMI gen 2 thing in BIOS

Nothing above helped. Im left with two options I guess - fresh win install or try older Catalyst drivers? Any help will be appriciated.

Thanks
 
i managed to "fix" it. Everything works fine when PCIe is set as Gen2 in BIOS. When its in Auto or Gen3 mode than Im getting cold boot performance issues.
 
Update: I've found permanent solution. Once my memory was set to X.M.P. Profile 1 in BIOS (so its running at 2400Mhz) - my card has no issues with PCIe whatsoever.

My GPU: SAPPHIRE R9 285 2GB GDDR5 ITX COMPACT OC Edition (UEFI)
My RAM: Kingston Beast - HX324C11T3K2/16 - DDR3-2400 CL11

Any idea why enabling X.M.P allowed me to run my GPU at "full" PCIe 3.0 mode???

Thanks
