Phenom 9850 Quad Bottlenecking GTX 570?

Hello everyone,

I just purchased the GTX 570 (Monster of a card!!) but it seems to be behaving strangly.

Let me start by giving you the spec:

Asus M2N32SLI-DELUXE
AM2+ Phenom 9850 Quad Core @ 2.9ghz
6GB Corsair DDR 2 800mhz
700W PSU

My PSU has a digital readout on the back and under load it is showing as only using 400w under load.

When running fraps the fps are irratic jumping from 20fps - 100fps! Opening credits / videos seem slow and seem worse than with my old GTX 275.

On f1 2010 i used to get 50fps with my old GTX 275 im now getting 20 - 40 with the GTX 570!!

GTAIV is also worse running at about 20fps outdoors but over 120fps indoors and counting up really fast then getting to a certain point and going all the way down again.

DIRT 2 is running at 40 - 50 FPS maxed out on ultra settings (dx11) but microstutter all over the place.

Black Ops runs at 40 - 100fps everything maxed out but again has bad stuttering.

Could my 9850 be that much of a bottle neck?

Any help appriciated.

Daryl
 
What drivers are you using?

The 9850 will be a bit of a bottleneck, being slower than a similarly-clocked Athlon II, but it shouldn't cause it to act strangely like that.
 
Hi,

I have downloaded the latest drivers off the nvidia website.

Some games work great...COD MW2 im getting a silky smooth 90 - 300fps and Bioshock im getting 90 - 200fps.

BUT

In DIRT 2 im getting 40fps and f1 2010 20 - 30fps!!!

Also getting a few display issues where every game stops responding when loading up for about the first 10 seconds before the intro credits.

700W PSU....Jeantech Storm. Its only using 300w under load.

Oh and i've managed to overclock my CPU to 3.11ghz :)
 
dont know if this helps any of you (my system):

OK i'm getting 30 - 70fps in fsx which is fine (i know this is more CPU dependant)

I'm also getting 70fps with dx11 in DIRT BUT its jumpy and doesn't look right. Just trying to patch it.
 
That powersupply is a poor quality unit. More wattage does not mean it is better. Microstutter can be indicative of poor power.

In your case, I would get the following:

CPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103871

PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151095

A newer CPU, which your board supports (see http://support.asus.com/cpusupport/..._mkt.aspx?slanguage=en-us&name=M2N-SLI Deluxe ) and a decent powersupply to ensure clean power.

For reference, that Jeantech PSU is an OEM Sirtec unit, the same thing powering cheap 300-400w thermaltake powersupplies that have problems pushing even that much amount of power.

If you can't spend that much let me know and I'll find an alternative for you :)
 
I've put my GTX 275 back in and i'm getting exactly the same fps in every game as the GTX570 apart from the problems with DIRT2 , F1 2010, and GTA4 are now gone and working at a solid 60 - 70fps.

I'm gonna return the card and think again about what to upgrade.
 
Your CPU is the problem, hands down. No need to return the card, it's quite a bit stronger than a gtx275. Even your 275 is being bottlenecked by the 9850, which is why you get the same FPS.
 
You sure it isn't the poor quality power supply hindering his performance? He is using a Jeantech Storm 700 Watt Power Supply.

Probably.

No need, the CPU and/or PSU is the problem.

I stick by my recommendations I noted previously :)
 
The power supply isn't helping the situation, sure, but the CPU is a huge bottleneck. Even though it was 4 cores, Phenom I architecture is crap and 2.9ghz isn't helping either.

I just recently tested a Phenom 9650 at 2.7ghz and there was only a handful of games it could play decently, and they were the older games. I did try black ops, it did OK but there not noticeable stutter and a FPS bottleneck VIA cpu. Task manager showed CPU usage all 4 cores over 90%.
So basically, any newer game that can utilize more than 2 threads a Phenom will be crap for.


OP- The best CPU your motherboard supports is the Phenom II 945. I highly, highly suggest it as it will fix all you problems.

Update your bios to the newest, and stick that puppy in there. Problem solved...err, maybe get a new QUALITY PSU as well to make sure of that too-

^ +1. Yeah, the Jeantech Storm isn't a great unit, but it's not some Logisys fire-hazard supply. :) I would assume that it would be able to power the GTX 570, but just barely with a safe voltage.

To the OP: For safety's sake, download Speedfan:

Then check your PSU's +12v voltage with the GTX 570. If it's under 11.75v when playing a game, you might have a problem.
 
Speedfan's 12v chart is worthless. Couple times it said my 12v voltage was dropping down to like 5v under load but I checked the rail with a voltmeter and it was 11.97v.

Maybe it was buggy with your hardware, since it's relatively new. Either way, you can't lose anything trying. If the output is something crazy, then we'll just ignore it. :)
 
I've tried it on 4 different boards/setups and it was wrong everytime ;) (two 775 setups, an 1156, and a 1366 setup....3 different power supplies!)

It's worthless.
 
Yeah that Jeantec has to go regardless, low efficiency 72% and rubbish 12V rail amperage. CPU is bottleneck, but PSU has to go too.

Bad luck? :o Okay, so maybe it's often screwed up, but I've always had good luck with it so it can't always be wrong. :)

I was confused for a second. I thought it had relatively high efficiency. I looked up the specs and it said:
Super High Efficiency Maximum 84%
