Q6600 Dverb Test Unusually Low

[TOM@METRO]

I haven’t re-run the Dverb test on 8.0.4b yet but I do know that performance for me was greatly improved by installing a TI firewire card and driver. This was compared to the stock LSI chip and driver on the Asus board and also a VIA PCI card that I have.

I got a TI card for ASUS P6T right away. i7 520 , the old Bloomfield.

Much better performance and stability w / PTLE 7.4 compared to the onboard FW. Don´t ask me why. No errors, nada.

I have the "3GB switch" tweak done - and I only have 3GB of memory. Do you guys actually record the test tone while testing Dverbs? And buss the tone via auxes?

I got 410 old Dverbs this way on 7.4, almost 100 more when not recording / sending the signal to the auxes. BIOS is still default and XP 32 / SP2 stock.




Which way is the right way to Dverb test? I have 8.01 day tomorrow.

Chipset
Model : ASUS X48 Processor to I/O Controller
Front Side Bus Speed : 4x 401MHz (1.6GHz)
Memory Bus Speed : 2x 602MHz (1.2GHz)

Memory Module(s)
Memory Module : G.Skill F2-6400CL5-2GBPQ 2GB DIMM DDR2 PC2-6400U DDR2-800 (5-5-5-15 3-24-6-3)

My Q6600/P5B/DDR800 system is showing a FSB bus speed of 4 x 266 or 1066. The OP is showing a FSB of 4 x 401 or 1600MHz.

My DDR800 memory is running at 2 x 400 for a speed of 800Mhz. The OP is showing 2 x 600 for a speed of 1200MHz.

Whats CPUz reporting the actual RAM speed and timings at?

Is the OP performing the Dverb test the right way? Folks have been known to misunderstand the directions once and a while. EG using the second set of 5 track inserts on a track supposedly gives a performance hit over opening a fresh track.

As stated there nothing obvious in the Sandra report.

Hey there guys.

I am doing the dverb test correctly as far as I can tell, only five dverbs per track etc. Also, I do think the sandra report is my board's capabilities, not what I'm actually running at. Here are all the tabs from my cpuz:

cpu
caches
mainboard
memory (same on slots 1 & 3)
spd
graphics

Also, I'm running the 002r through the agere chipset pci card, and i'm not getting any firewire related errors.

I get to 80 dverbs with my rtas usage at around 83% (which seems absurdly high, it's only around 50-60 with my dual core 2.0ghz laptop) but as soon as I get around 85-90 my system locks up and I get a 9128 error.

Is there anything in my cpuz report that would indicates problem to you guys? I don't see anything unusual.

I've heard that PT sometimes has issues with nvidia cards... Have you turned the hardware acceleration all the way down on it?

Hey there, thanks for the response.

I have tried, but I'm still hanging at like 83 mono new dverbs.

[JonnyGinese]

Did you try adding dithers as the first inserts per channel to make sure it's not denomalizing?

[jmorganmitchell]

I did, and it hung at 60 dverbs while adding a new audio track.

It's got to be a hardware issue of some sort. I just can't figure out what it could be though for the life of me.

One thing that might help would be to set you timing at 4-4-4-12 for DDR2 800 instead of the 5-5-5-15 its clocked at. Your memory may or may not run at those timings but its worth a try.

Try deleting your Prefs before doing the D-verb test Sometimes that can make a differance.

My 002 has been running just fine off the Agere FW for a couple years now.

[JonnyGinese]

umm.. in his cpuz pics the module say 5-5-5-15 for 800

Hey this may be interesting:

After adding another three DDR3 1 G modules, my system chokes on the same sessions that run on 3 x 1 GB.

My test rig is i7 520 / P6T DL / XP32 , absolutely nothing optimized yet. But it works really well... better with 3 GB when loaded with RAM- heavy stuff... I did the "3GB switch" and with 3 GB onboard, PTLE 8.01 can use more than 2,5 G and run fine.

But when I have 6 GB installed, those same sessions will eventually crash while loading RAM. CPU use is higher as well.

Ideas?
