Lag during Dota

[FiCtioN75]

Hi guys. My spec is as follows,

Intel Core i5-4690K
AMD R9 380
Samsung 850 Evo 250GB
Kingston HyperX DDR3 2400 C11 2x4GB

I've been running dota 2 seamlessly for over 2 years, now ive booted my pc and launched the game and i'm getting pretty bad intermittent lag during play. I initially thought it was CPU lag as ive had problems with my cooler in the past but having ran a CPU temp programme none of my cores are going above 32 degrees.

Im a bit stumped so I ran a GPU benchmark programme and got the following results

UserBenchmarks: Game 46%, Desk 69%, Work 40%
CPU: Intel Core i5-4690K - 80.9%
GPU: AMD R9 380 - 45.4%
SSD: Samsung 850 Evo 250GB - 92.9%
RAM: Kingston HyperX DDR3 2400 C11 2x4GB - 33.8%
MBD: Asus Z97-K

The memory seems to be running slow and I got this message on the report - Performing below potential (7th percentile) - ensure that a dual+ channel XMP BIOS profile is enabled

I also ran a speedtest and my net was running at 35 download and 8 upload so that kind of eliminates that problem. Im not one for tinkering with anything so nothing has changed since I last had a game 2 days ago when it ran dota perfectly.

Any help would be greatly appreciated, thanks.

post the mem results ie
2 of 4 slots used
8GB DIMM DDR3 clocked @ 2400 MHz

and from multi core

MC Read 30.9
MC Write 33.6
MC Mixed 27
87% 30.5 GB/s

sounds like bios has reset to defaults , switching off xmp profile

Hi, thanks for your quick response. I can confirm that the bios had XMP disabled, which I went ahead and enabled on profile 1, however having launched dota again this doesn't seem to have resolved the issue.

Here are the results having enabled XMP

2 of 4 slots used
8GB DIMM DDR3 clocked @ 2400 MHz

MC Read 16.8
MC Write 16.9

Thanks again lude1962

check dual channel enabled in bios (not sure its an option)
what slots are the chips in ie 1+3, 2+4 ?

 

[FiCtioN75]

I just had a look through the bios and I couldnt see anything which would suggest dual channel wasnt enabled. Although my knowledge of the bios and how to navigate it is fairly basic.

My ram is installed in the 2 slots closest to the CPU cooler, they were marked in the bios as the following.

DIMM_A1
DIMM_A2

Thanks

 

[lude1962]

mem should be in A1 and B1 for dual channel

Should I move one stick over one slot and re-try? I haven't changed the slots since a friend first built the PC so im confused as to why it would start lagging all of a sudden, strange!

 

[lude1962]

you use the 2 black slots (they're colour coordinated 2 black 2 grey, how your friend can get that wrong )

Ok ive changed the ram over however the lag is persisting. Ive re-ran the benchmark with the following results;

Intel Core i5-4690K

Everything seems to be running as expected, im starting to wonder if this is a settings problem, maybe ill try unistalling dota and re-installing. Worth a try?

Thanks for your help, its greatly appreciated.

Well a clean install of Dota hasn't achieved anything. I'm really puzzled by the benchmark test showing me everything is performing as it should be.
