FPS drop across all games making them choppy/unplayable - HALP PLS! - Page 3

post #21 of 42
You know Im dealing with this same issue right now and have gone through a lot of swapping and testing.
post #22 of 42
I know its extremely unlikely, but maybe try different driver. I know you reinstalled windows, but maybe you used the same drivers as before

on a side note, unless you plan on upgrading stuff in the process I wouldn't start blindly replacing things in the hope that it will solve your problem. with some invested time in diagnosing the issue you can save yourself some money in the long run

Here is what I have tried so far with my problem, (keep in mind I have high FPS during the stuttering).
CPU: PHenom II 6x 1090T
RAM: 4x4 = 16GB DDR3 XMS3 Corsair RAM
GPU: HD 7870 GHZ edition
MOBO: Gigabyte 970A-UD3
SSD: Kingston Hyper X 3k 240GB
750W PSU

Ran numerous tested including Memtest with no errros. Clean Install and all that jazz.
I swapped out all 4 RAM sticks for a 3 set from HTPC, plugged in and had no problem. So started testing out RAM. put original RAM back in 1 and 3 slot only, tested fine. Then tested 2 and 4, ended up with choppiness. Tested both sticks of RAM in slot 2 with no problem.
Meant something going on with slot 4 on the MOBO side.
Decided to test out old video card, 6870 and plugged all four Sticks of RAM into slots. Played for a while without having an issue.
\Going to through my new 7870 into the HTPC and test if there is stuttering. If it stutters it will mean that the GPU is the issue, if not then the MOBO isnt transferring Memory correctly for some reason. Faulty Board.
If it doesnt stutter on HTPC I will also try it in second PCI-e slot to see if it has something to do with PCI-e slot 1.
I can only assume since my 6870 is working fine in the 1st PCI-e slot then there wouldnt be an issue with the MOBO with All four RAM slots filled.

So its a funny conundrum. Could be GPU or could be MOBO, but MOBO works fine with older GPU, but not newer (power draw issue maybe?). Depends on tonights testing. Failing memory in GPU maybe.

Im thinking its more of a hardware issue in line with my problem than software, since all drivers are updated, even the BIOS. and installing older version of these drivers does nothing.
I would think that if it were driver related we would hear a lot more about it and there would be more problems out there to read about.

So did a hdtune last night which came up fine, taking the HDD out of the equation. Didnt have time to run a memtest but the wife is out tonight so I'll get it done then. I also tried running things through my second monitor without much luck (still quite choppy).

@ Bradley
I tried locking my fps like you suggested, still had the same problems unfortunately.

@the d0ctor
Totally agree, Im not really blindly replacing, Ive only got my eyes on things that I have wanted to upgrade anyway.

@Realism
Thanks for posting, your input has been quite helpful, keep us updated on how you go with it mate.

Im leaning towards my problem being related to the mobo, which would be one of the better outcomes as I can pick one up quite cheap.

Can anyone give me some insight as to how hard it is to fully replace my mobo myself (1st timer), I've never messed with one before, only the other components...
post #26 of 42
Replacing MOBO is pretty easy and straight forward, the only tricky part as a first timer may be with applying correct amount of Thermal paste on your CPU plate and not having some squeeze out when you put your heatsink (stock or not) overtop. Pretty easy though if you watch a few youtube vids to get an idea of about how much to use and which way is best for you to spread it on there...Some use a small pea sized amount in center and plop the CPU on there, me personally i like the guarantee of equal spread so I use a business card (card stock is great for this) to thinly spread the paste around so it doesnt squish out.
Wear some non static gloves if you are particular about getting the paste on your fingers or clothes, It may not come out of clothing. (ive got small spot on the kitchen table chair [cloth] wont come out, hope the wife never notices. ) biggrin.gif

Mostly tricky thing for me is installing the CPU cooler to the best of your ability.

Try this. If you have MOBO with 2 PCI-E slots, put your GPU into your second PCI-E slot and tell us how it goes. I tested my GPU on different computer last night with no problems, put my 7870 into the second PCI-E slot on my MOBO and stuttering was almost non existent. Its looking like failing PCI-E slot
post #29 of 42
OP didn't see you try this...

Load up GPU-z and either run a 3d program in a window state in the background or run the GPU-z render option.
Look at the scaling portion of the GPU report.
It should say PCI-e 3.0 x16 (or 2.0 x16)

If it is stuck on PCI-e 1.1 x1 or PCI-e 2/3 x1 then there is most likely a hardware issue.The GPU not staying in the correct state would cause FPS drops in all games. This could either be a Mobo or GPU issue.

Tried the GPU in both slots, same result frown.gif

@Apparition
I'm almost certain this is a hardware issue and I bought a new GPU on the weekend as I thought that was the cause of the problem, however it wast and I'm still getting the same fps problems, hence the assumption its my mobo or the RAM
