Another Gigabyte P35-DS4 revision 2.1 user.

Has the same off-beat, 'staircase' type pattern:-



The mobo is paired up with a Q9450 2.66GHz CPU, which, because it's a new Yorkfield chip with 1333MHz FSB, cannot use BIOS revisions earlier than F9.

Full system specs:
* Intel Q9450 2.66GHz CPU
* Gigabyte GA-P35-DS4 revision 2.1
* 2 x 1GB Corsair DDR2 PC6400 CAS4
* 512MB MSI nVidia-based NX8800GT Zilent graphics
* 2x500GB WD Caviar RE2 SATA-II drives
* Samsung SH-203P DVD-/+ Rewriter
* Mitsumi FDD with multi card reader.
* Corsair 520W HX PSU
* Windows XP + SP2.

I tried it overclocked, and stock clocked. Exact same pattern. I'm using F3, but I tried F1 and F2 and the problem remains. I even did a clean install of XP Pro, without any additional drivers, and the pattern is the same. I, too, have an nVidia graphics card, and SATA II drives, connected throught the Intel chipset. I also have a PATA DVD-RW connected through the Gigabyte (it's actually a jMicron) chip. I've disabled it, but the pattern remains the same.

Yep, I've put mine through the mill. That same pattern is there right after a clean Windows XP install (absolutely nothing else installed), and remains like that at any time onwards (after all chipset/graphics/LAN/audio etc drivers are installed, and after any of the usual XP tweaks are carried out).

Oddly, if I start the DPC monitor ASAP after the Windows desktop has booted up, the latencies are nice and low for a good few seconds before the spikage starts (as shown in the following screengrab), which may be important (before a certain Service is loaded/executed at startup)?

However, I've already disabled every non-critical Service, and disabled every non-critical device from Device Manager (including the usual ethernet/LAN, DVD-RW, onboard audio etc.) to no avail. Have even gone as far as completely disabling USB and firewire, and using a PS/2 mouse and keyboard. Also disabled System.ini and Win.ini from Windows startup.

Already contacted Gigabyte today (waiting for a response). The motherboard is still currently within its short 7-day RMA period too, so I've gotta move quick.

Timo,

Did you direct GigaByte to view this thread so they can see that it is an issue that is causing problems for a number of folks? If they get an idea that news of this is beginning to spread, they may move a bit quicker to find a fix?

It's been a week since I contacted them and still haven't heard anything. I have to decide whether to return it in the next couple of days, too. I'm not really seeing any problems in performance, are you? I know some people are getting dropouts and other problems, especially in Cubase. I'm mainly using Sonar, but also GS3 and Wavelab. I have found I get much better performance in Sonar with WDM-KS drivers than with ASIO drivers, with my Delta PCI soundcards.

Have ammended my support mail to them to include this thread (on the Cakewalk forums) and one on Tom's Hardware about the same issue: http://www.tomshardware.co.uk/forum/247210-12-audio-latency-problem-ds3r

Time's ticking though. It seems to be moving slowly on the Gigabyte front, but I only have around 2 or 3 days left before the RMA period of my mobo elapses. Unsure what to do. Will attempt to do another load of trouble-shooting on the system tomorrow, and also see what Gigabyte say first. Think I'll have to contact Scan.co.uk (my retailer) to ask their advice regards RMAing, too. I think you have 7 days to claim an RMA, and once that has been accepted 28 days are given to send it back to them, which might give a little more time.

Would be great if Gigabyte fixed it, though, the board is otherwise excellent with regards to its connectivity and enthusiast clocking.

Does that motherboard use a P35 chipset? If it does, then I have to believe that if Asus can get that result, so can Gigabyte. Do you see any performance differences between te Asus and Gigabyte boards?

Yup, P35 chipset, minus the onboard TI-based FW controller. The ASUS has a VIA-based FW controller, which is why I decided to toss the GigaByte into the DAW. However, I may just swap this out over the weekend if there's no easy fix for this.

Timo,

I would suggest you send the MB back while you still have the time to do so. Report it as defective, using this and other forum threads as your proof. GigaByte needs to pull their heads out of their a$$es on this issue. They are marketing these boards as high-performance, but they are not performing that way.

...unless the test is not accurate or something.

Is that simply the P5K, or one of the other P5K-* boards? I'm thinking of returning my Gigabyte for the P5K Pro, since I need PS/2 connectors for my KVM switch. I also need firewire and at least 2 PCI slots.

It's really too bad. The Gigabyte seems very well made, and that was the reason I decided on it. I never came across any of these latency problems when researching it before I bought it.

I have both a "P5K" and a "P5K-SE." They both perform the same with the DPC test. The P5K-SE is a stripped down version of the P5K, without a FW controller.

And yeah, bummer about the GigaByte, but I think I may still be able to return mine. If I can't I may try using the P5K-SE with an add-on FW card.

Has the same off-beat, 'staircase' type pattern:-





Mine (see my specs, I have a F12 BIOS) looks alot like this. I just have not loaded my picture anywhere.

Also I have an older Gigabyte 8IPE1000 with a P4 925/on-baord TI Firewire, and a MachSpeed P4MST-890 with a P4 930/ PCI TI Firewirwe that both look very much like Mr. Moon's Asus P5K.

Well, I hate to bail on the Gigabyte motherboard, but I had to make a decision since today was my last day to return it. I sent my first email to Gigabyte about this problem on April 5th, and another one on the 8th, and still haven't heard from them. So I got an RMA for the Gigabyte board and ordered an Asus P5K Pro. I'll let everyone know if it suffers from the same problem, since all the other hardware and software will be the same.

I really like the Gigabyte board, but I have to say it is very annoying that they have not responded to my requests for assistance, especially since I told them I was under a time constraint.

RE: Gigabyte P35 motherboards and DPC 2008/04/18 08:36:32 (permalink)
As of this morning, April 18th, I still have not received a reply from Gigabyte Tech Support about my inquiries on April 5th and 8th. Disappointing, to say the least. I have set up an RMA to return my GA-EP35-DS4, but I'm hoping to have a fix, or at least the promise of one from Gigabyte, before I return it next week because I really like the board otherwise. I have ordered an Asus P5K Pro (P35 chipset), which should arrive Monday, and I'll transfer all of my hardware and software to that board and see if it makes any difference in the actual performance with audio programs. There may be no difference at all, even without DPC latency spikes. If that's the case, I'll have to decide which board to keep and pay a restocking fee to return the other one.

EDIT: Ohhh, I'm sorry Dan I thought you had the DS3P. Just Mr. Moon and Me I guess. But it does seem like they are trying to fix it so maybe you'll get your reply soon. Sorry for the false alarm Dan.


Original Message:

Dan,

I have been waiting longer than both You or Mr. Moon for a bios fix, and they finally sent it last night. It took them long enough, but I can't try it out because I'm leaving town this morning; and have already replaced the EP35-DS3P with an Intel dp35dp (which is running well after the recent BIOS fixes from Intel). Anyway I hope to come home next week and find that it worked for ya'll so I can put this extremely sweet board back in my rig. Here is the link:

Good Luck,

Jason

Hi Jason,

Well that's encouraging news. At least they are working on a fix. I wish I had known that before ordering the Asus board. I hope Mr. Moon can test it and let us all know if it solves the problem.

Yeah, I'll be holding onto my GigaByte board (too late to return it), and will try any BIOS/software patches they release to fix it. If someone could email me to let me know when they release patches, that would be awesome!!

I just grabbed the file and will may try it out later today, once I look it over a bit to make sure it is OK. Not that I don't trust you, but I work in IT security and am a bit wary of BIOS updates and such from non-official sources. If you could post the link to the source of this file, or the relevant site or forums discussions, I'd feel much better about it.

I'll post the results once I try it out.

EDIT: I just got the "official" link via email and so I will probably try this out later today/tonight, depending on how cooperative my 2 1/2 yr old is!





Thanks!!

Hey thanks heaps Jason! Downloaded fine.

I'll try flashing it now. Hopefully I'll be back in several minutes to post my findings!

It's definitely the EP35-DS3P! I used to have a non E version until it died a few weeks back and the shop I bought it from replaced it with this one! I feel lucky I haven't been waiting as long as everyone else here...

Anyway thanks again! Enjoy your weekend

Since you guys will be checking DPC Latencies while you guys are updating BIOSes and drivers, in case you are still left with spikes, here is another tool that may help you sleuth out which device/driver is the culprit. It's an MS utility called RATTV3:

http://www.microsoft.com/whdc/DevTools/tools/RATT.mspx

I just caught this on the other Gigabyte DPC thread, so I haven't run it (I still have old machines, so I don't have this problem yet)! Maybe it can help?
