GTX 460 high latency DPC and BSOD issue
  1 / 4    
Hi. I'm new.

I'm Zuri from Poland.
First of all, sorry for my poor english.
I've search all the forum about problem, I noticed similiar a little bit topics, but I would like to expand the problem.
I've noticed this is not only my problem as well.

My setup:

[b]Mainboard:[/b] MSI P35 NEO2-FIR
[b]Power Supply Unit: [/b]Chieftec APS-550C 80+
[b]Processor:[/b] Intel Core 2 Duo E8200 [OC 3,6 GHz]
[b]Memory:[/b] OCZ Technology 2x 2GB DDR2 800MHz Reaper EPP CL4-4-4 Heatpipe
[b]Graphic Card: [/b]Gainward GeForce GTX460 GS 1GB
[b]Audio interface: [/b]TC Konnekt Live
[b]Audio DSP card: [/b]UAD-2 (PCI Ex x1)
[b]Operation system: [/b]Windows 7 x64 Ultimate


First I had a [b]8600 GT[/b] on Windows 7 x64 Ultimate - no issues. Works perfectly. 3dMark06 results:[b] 5500[/b]
Next, I bought [b]HD4850[/b] also on Windows 7 x64 Ultimate - no issues. Works perfectly. 3dMark06 results: [b]12500[/b]

Now I've got a new card [b]GTX460[/b], and I've got following issues:

1.[b] High DPC latency[/b]: about [b]7500us[/b] when it's in[b] Idle[/b].
When [b]GPU[/b] works in [b]3d (games, etc) DPC latency drops to 40 - 60us (sometimes are spikes to 7000us)
[/b]
2. Because of [b]High DPC latency[/b], [b]ASIO buffer size[/b] can't be [b]lower than 224 samples[/b], and Audio Interface must be works on [b]Safe Mode 2[/b]. Sometimes Audio has got [b]glitches[/b].

3. I think because of High [b]DPC latency sometimes[/b] I got[b] BSOD[/b] (I can't remember the code, something like 0x00000001)

4. [b]3dMark06[/b] Score is too low for this card. I've noticed in internet tests, people has about 18000 - 21000 score, I've got [b]16100.[/b]


[b]What I did to solve that problem:[/b]
1. I tried to turned off antivirus. Problem still persists.
2. I unistalled audio drivers. Problem still persists.
3. I unistalled DSP card drivers. Problem still persists.
4. I turned off the ethernet card. Problem still persists.
5. I reinstalled operation system
6. Even I tried to unplug keyboard, mouse. Problem still persists.

And... More interesting... :)

I tried to uninstall [b]graphic drivers[/b]. Issues are gone![b] DPC latency [/b]is low like hell -[b] 20 - 50us[/b], [b]no BSOD[/b].
Audio interface can be runned in Normal Mode (even in 64 ASIO buffer size).
Beautiful clear sound after this operation.

[b]Conclusion?[/b]
I'm sure in 100% that issues persists because of [b]NVIDIA driver[/b]. I read forums about similar problems and It seems [b]NVIDIA drivers[/b] doesn't work good with [b]P45[/b] and lower Chipsets...

I'm very, very unsatisfied... Is there any fix for it?

I'm sure in 100% that issues persists because of NVIDIA driver. I read forums about similar problems and It seems NVIDIA drivers doesn't work good with P45 and lower Chipsets...

Since you already know that the problem lies with the Nvidia drivers and only applies to GTX460 on P45/X48 or lower chipsets, the only thing you can do is wait until Nvidia releases new drivers that fix the DPC latency problem. Nvidia already knows about the problem and has said that they will fix it, although they have not indicated when they will release the fix. If you don't like waiting, return the GTX460 and get something else like a GTX465/470/480 or even go ATI.

As for the supposedly low 3DMark06 score, I think it's the rest of your system (CPU, chipset, DDR2) that's bottlenecking the card. Actually, I think your CPU is good enough, but that P35 chipset and 800MHz DDR2 is killing the GTX460's performance. Also your mobo probably still only supports PCIe 1.1, not PCIe 2.0. Anyway, I believe your score is about right for your system. If you want to reach 20000, get a Core i5 with DDR3 and a modern chipset like the P55 with true PCIe 2.0.

jup this Problem is known by nvidia but nvidia didnt said something about it..i found these issues a long while ago and tried to contact nvidia with no luck, so i went to GIGABYTE since i have my card from them, and see tehre, they were listening and reproduced it, they also get in contact with nvidia..so lets hope they will fix this soon ;)

I didn't know, I got broken card or what... Anyway I'm gonna to buy new mobo with p55, i5 and ddr3. I hope that problem will not return.

PS. This is so funny that I can't do anything with sound producing because of... graphic card (drivers) !

I didn't know, I got broken card or what... Anyway I'm gonna to buy new mobo with p55, i5 and ddr3. I hope that problem will not return.

PS. This is so funny that I can't do anything with sound producing because of... graphic card (drivers) !
[quote name='Beta2013' post='1104749' date='Aug 17 2010, 12:24 AM']jup this Problem is known by nvidia but nvidia didnt said something about it..i found these issues a long while ago and tried to contact nvidia with no luck, so i went to GIGABYTE since i have my card from them, and see tehre, they were listening and reproduced it, they also get in contact with nvidia..so lets hope they will fix this soon ;)

I have a mobo with P55 chipset (MSI P55-CD53), Core i5-750 Lynnfield OCed to 3.3GHz, and 4GB dual channel OCZ XMP Ready Series PC3-12800 1600MHz DDR3. No problems with my MSI Cyclone GTX460 1GB OC, no DPC latency issues, and I can reach 22000 in 3DMark06. The GTX460 and current drivers just seem to like the P55 and Core i5. If you can afford it, the upgrade will be worth it. :)

I'm getting DPC latency spikes as well.

But I'm on an AMD 890GX based motherboard (ASUS M4A89GTD PRO/USB3).

Hmm, I'm starting to suspect that the DPC latency issues in the GTX460 affect all motherboards with chipsets -other- than P55 and possibly H55. I guess Nvidia probably didn't test their drivers in systems that use chipsets other than P55/H55.

On the other hand, occasional spikes is normal depending what the system is doing at the time. The first 3 pics seem okay, but the 4th one is suspect. Was your system doing anything when you took those screen captures, especially the 4th pic? If your system is idling (not doing anything) and you keep getting more red lines than green lines, then for sure you have the DPC latency problem.
