Performance issues asus m5a87/FX-8370 caused by vdroop

[aurill]

I have some serious fps drops in games caused by vdroop (if that's how it's called)
I tried to change bios settings (turning on/off llc, cool n quit etc.) and it didn't really help

My specs are:

Motherboard Name Asus M5A87 (3 PCI, 2 PCI-E x1, 1 PCI-E x16, 4 DDR3 DIMM, Audio, Gigabit LAN)
CPU Type OctalCore AMD FX-8370, 4000 MHz (20 x 200)GPU Sapphire R9 290X 4GB
GPU Sapphire r9 290x
DIMM3: Kingston 9905471-017.A00LF
DIMM4: Kingston 9905471-017.A00LF
Disk Drive OCZ-VERTEX3 ATA Device (SATA-III)
Disk Drive WDC WD5000AAKX-001CA0 ATA Device (500 GB, 7200 RPM, SATA-III)
Power Supply Thermaltake TR2 RX Series 650W

You have the new wraith cooler on that chip??

Irregardless that old m5a87 has issues with anything past the 8320@stock speed.

Its 4+1 phase & not really suited to your CPU.

What's the exact issue - assume you're getting clock drops under heavy load ??

Disabling turbocore can help as it also disables APM ,but not guaranteed.

I have Thermalright Macho Rev.B, so the temperature is not really hight.
Clock drops happen under heavy load, when the temperature goes around (55 C)

I'll test it with turbo core enabled.

Looks same (you can see here the drops)

I know this may be caused by motherboard, I just want to make sure it's her fault before byuing a new one.

According to those images you posted, you are massively overloading the power delivery system on your motherboard. I had an Asus M5A99FX PRO R2.0 which has a 6+2 phase power delivery and I never had problems with V droop.

Also, the CPU socket targets 55 Celsius as the point where it starts to throttle. You're not seeing above 55 Celsius because BIOS is hard coded to keep it below that.

You need a better motherboard and a more capable cooler.

I recently bought a new cooler (Thermalright Macho Rev.B) because my old one was noisy and bad. But the thing is it was vdrooping around 70 C (not 55 as now).

Oh, I didn't see you had already upgraded your cooler. I still say your motherboard is a problem though.

So basicly it's caused by old motherboard / 4 pin power supply for CPU (which is not enought for 8370)

and if so

what motherboard would you suggest for this setup?

yes mate ,I did say to disable turbocore though .

before with your old cooler (assuming it was the stock amd downblower) you were sufferring plain & simple cpu throttling due to cpu temps.
What youre now seeing is the board throttling due to the vrm temps ( the vrm's are those 5 black chokes to the rear of the cpu socket)

the downblower cooled the vrm setup so you were hitting a higher temp threshold before.Dropping that tower cooler on there removes that vrm cooling so theyre now overheating under heavy load.
Cpu & socket temps have no direct correlation to vrm temps,apart from a hot vrm setup will heat the whole board area around the cpu & add maybe 5c or so to the cpu temps aswell)

Id argue with a better choice of cooler you would have got away with the board,the thermaltake axp 200 or raijintek pallas would have been far better cooler choices.
Really though its not good enough for your 8370 at the end of the day.

good board ,expensive though,id just go with the ud3p

http://pcpartpicker.com/product/Vrdqqs/gigabyte-motherboard-ga970aud3p

plenty good enough quality for the 8370,inarguably better than 90% of even 990 series boards when it comes to outright vrm setup quality & voltage regulation,

My bad, misunderstood about trubo core.
Now I'm being sad for bying macho b. Do you think it would not be a probleme with ud3p?
I actually had zalman CNPS7500-Cu. May be I should switch back to him.

Thank you for you replies.

the zalman before offered decent board cooling but is nowhere good enough to keep a fx 8 core cool.
the thermaltake you own now is a good cooler & fine for the 8370 but offers no baord cooling.

running the 8370 on the gigabyte ud3p with the macho cooler will not be an issue at all - it will be absolutely fine,the gigabyte has no issues with vrm throttling whatsoever with any fx8*** cpu
make sure it is the ud3p though & only that (the ds3p,d3p,ud3 are not good enough)

Ok, thanks!
I'll reply back after replacement is done.

I installed gigabyte ud3p a few days ago. Your guess was totally right.
It's finnaly working like a charm for me!

Thank you for great advice.
